Our building in Brooklyn has had ongoing water issues for many years. Contractors have tried to repair and fix the issues, costing us time, money, and compromised quality of life. JP Diagnostics were able to locate the multiple sources of water entry, providing a detailed report of water entry and recommended solutions. They were also able to recommend a contractor who does quality work. After the project was completed, Jarrod and his team followed up and was able to locate one area of water entry that still persisted. His work and advice were invaluable to solving our water leak issues and our only regret was not hearing about JP Diagnostics sooner! Highly recommend giving them a call if you have unsolved water entry issues. read more

The owner Nick and his employee Tim diagnosed my problem in no time flat and went above and beyond with extraordinary customer service and got me back on the road in 15 minutes. And the price was amazing. Thanks fellows you got my vote! read more

I used JP Diagnostics on 3/17 and followed Jarrod's recommendations used a contractor he recommended. Some leaks were repaired others still leak. The contractor followed Jarrod's recommendations and when they didn't work he blamed the contractor. Which means if Jarrod gets it wrong he will never be accountable and you will continue to spend money on repairs that you may not have needed in the first place. Jarrod was suppose to set up a meeting between the 3 of us and it never happened. I worked with the contractor myself and Jarrod walked away and stopped taking my calls on 3/28/18 with another year left on his warranty. Jarrod's service's are a waste of time and money take your chances just using a waterproofing contractor. Response to Jarrod's post. You did not recommend what you posted. I have your report you did not recommend removing all the bricks and waterproofing the substrate the only thing you recommended was repointing or using a sealer after your other recommendations failed. I would love to see the emails you are speaking about with this new recommendation. I don't care how many text you get if someone's spending their money on your services you need to respond I had another year left on your warranty and not responding is unprofessional. I posted this 3.5 years later and now you respond 3.5 years later. Look at Sarah M and Jose R reviews he did the same thing to me. It looks like the only way to get a response is to write a review because Jarrod doesn't respond to text or calls. DON'T WASTE YOUR MONEY ON THIS BUSINESS. read more

JP Diagnostics - Text to Jarrod you can see he read the text and did not respond with a text or call. - Plumbing Near Me

Our home was having multiple leaks and I learned of a very special technology that can trace the source of the leak and how to fix it. We hired JP and his team and are beyond grateful for what this technology showed. JP was the most knowledgeable and kind and prompt at my home. His team updated me with ETAs of the reports and took great care of me. I can say with 1 million percent certainty that If everyone used this technology before purchasing any building or home your life would be easier. read more

Creme de la creme of professionalism. I'm a first time homeowner who has had nothing but problems with my roof. Jarrod and the entire team at JP Diagnostics have been great with my (lack of) knowledge when asking questions about process, pricing, etc. Beyond being nice people, the quality of the reports that were issued to me were easy to understand and utilize for my roof repairs/homeowners insurance claims/etc. Can't recommend the team at JP enough. read more

Jarrod from JP Diagnostics investigated a structural leak in my condo building in Brooklyn. Jarrod and his team are trustworthy, professional, and timely -- a combination that's very hard to find in New York's construction and contractor industry. Jarrod returned calls, was on time for appointments, and was thorough in his investigation. We've had other contractors look at the same situation, and within minutes they start with unfounded theories, ideas, etc. In contrast, Jarrod started by collecting data and thoroughly tracing the water leak through the building's structure. During the investigation, he explained what he was seeing but avoided going into hypotheticals or speculation. The report that JP Diagnostics provided came within a week. It was clear regarding their conclusions, and Jarrod was available to take me through it on the phone. That was the only time that he provided additional ideas and suggestions based on his expertise with situations like ours. I found these to be useful and valuable (and they did not immediately call for us to spend more money with him or related entities -- a good sign). I will be using JP Diagnostics again once we have repairs in place, to validate the work. I highly recommend JP Diagnostics and Jarrod for leak detection and waterproofing consulting. read more

Imagine that for some crazy reason a company like Apple or Google or Tesla decided to jump into the leak detection business. That's how I'd describe JP diagnostics, because they leverage cutting edge technology and are light years ahead of the typical contractor in terms of their thoroughness and professionalism. When other contractors came to look at the stubborn leaks in my property, they basically stared at it for a few minutes and said something like "Gee I don't know, it could be this, it might be that . . ." From JP Diagnositcs I got a an extremely detailed and professional looking report that looks like it was prepared by a Wall Street law firm or investment bank with infrared photos etc that appear to pinpoint the exact cause and location of my leaks. What's more, Jarrod took the time to discuss his report with me at 10PM -- that's a refreshing change form the typical contractor that tends to bark at you and ask you if you know what time it is if you call them after 4PM. My only caveat is that because I just received the report yesterday, haven't had the chance to implement the recommendations contained therein. However, I'm highly confident that the report is accurate. It's much like when you read an article in, say, The Wall Street Journal, where you don't personally verify all of the information contained therein, but you still know that it's accurate. That's the way I feel about the report I received form JP Diagnostics. I only wish that the company offered a broader range of services -- they appear to focus on leak detection -- so that I could call upon them more often, as they are truly a pleasure to work with. If you're in need of leak detection services, look no further. Your search is over. Hire them. read more

I contacted JPD after getting referred by a roofing company that was unable to figure out where my leak was coming from. JP was very responsive through e-mail and arrived on time for the appointment and paid for his services accordingly. In terms of his services, his diagnostic was completely wrong and almost cost close to $10,000 on getting a window waterproofed when the problem was actually the flashing of the roof. It felt like he was rushing to leave and didn't bother going up to the roof to do his scan. I would probably recommend him for internal leaks in bathrooms. In terms of the tools, it was a FLIR scanner that could have been bought with the amount that I was charged. 09/21/21 Update: Jarrod has been issued a refund read more

Our 8 unit co-op has wasted so much money. We put in a new roof and waterproofed our walls yet we are still left with leaks or rather floods in most of our units. We hired JP. Jarrod of JP's biggest asset above a thorough, complete and thoughtful report,  is that he is a decent human being.  He has never been late and is actually always early. He is completely respectful to each unit he enters. He communicates clearly and promptly. He diagnosed the interior and exterior thoroughly and came multiple times when the results were unclear. I have already recommended JP to 3 of my friends' buildings.  As a co-op board member, I have to deal with every type of contractor and JP continues to be at the top of my list.  They have even extended our guarantee as Covid/Omicron life during winter made it impossible to continue actual repair work. Jarrod continues to answer questions patiently and promptly as we are preparing for repair. Jarrod's kindness and decency, I think, will create gratitude and loyalty in his clients. I now have to hire an engineer and try to make the Roofering and Masonry company accountable, but I have little hope. I wish I could hire JP to do all the work! read more

Pinpoint accuracy every time. We've used JP three times on separate water infiltration issues at our townhouse. And the analysis has been accurate every time. We have shared the analysis with JP recommended contractors and they have used it to rectify the water infiltration. read more

We have used JP Diagnostics on two separate occasions so they really deserve 2 reviews from us....But, I was slow to write the first one. Jarrod came out promptly when I was at my wit's end with a continuous bath tub leak/ repair cycle. Finally, I looked up waterproofing and he came up! What a brilliant technology! I was being offered to rip out my brand new bathtub, breaks walls and closets- and with some quick pictures and diligent report, Jarrod saved me from all that! He identified the exact area where the water was cascading, what needed to be done, and knock on wood we are going on 6 months with no leak from that tub! Now, we developed a strange leak on our first floor apartment. Directly above the leak we have, a fridge with a water line, an HVAC AC unit, a washer dryer, and a bathroom adjacent to that. Four possible culprits! This would be maddening. I quickly remembered JP Diagnostics and called them for help. Guess what? NONE of those were the culprit! The leak was coming from 2 AC units on the 3rd floor!!!! I would have never figured that. The way the water is cascading down, it is bypassing my 2nd floor ceiling and going down to the first. If it wouldn't be for Jarrod and his team, this would be an extremely expensive proposition looking, probing and figuring out this leak! I don't have enough words for a thank you. Only that I hope I won't need to use you guys again, but if I do, I will always remember to call you first! Beside extremely useful technology, Jarrod is pleasant, punctual and an absolutely the nicest, most professional contractor I have ever dealt with! Thank you, thank you, thank you! Here are some images to help you understand how this all works! read more

In a previous review I gave one star. It was based on JP Diagnostics's inaccurate attributing a drain system failure to our building which does not have a drain system in the area they analyzed. They will correct and rewrite their report to reflect it was the drain system in the building contiguous with ours with whom we share a common wall. Would have been good if they'd written the report correctly in the first place. read more

I couldn't be happier with with JP Diagnostics, from my first phone call to my last. The company is knowledgable, and extremely affordable. Jarrod was on time, professional and courteous. The company uses some really high tech equipment and Jarrod was more than thorough. He actually found two seperate water leak sources coming from the apartment above mine that we didn't realize was occurring, which makes complete sense now. The reports that he gave us in conclusion were so accurate that our insurance company even made comments on how impressed they were. Hopefully I won't have to use Jarrods company again, but with our upstairs neighbors with three kids, who knows! Highly recommend JP Diagnostics. read more

2.5 stars. I have water coming up through my basement floor but was confused about how to fix it. I contacted JPD and talked to a staff person who said they'd call me back. They never called me back. I called back 5 days later and made an appointment. In the first five minutes of walking into the house, before performing any diagnostics, the owner of JPD recommended cleaning out the basement drains ("Why don't you just clean them?"). He then conducted infrared diagnostics and drone pictures in about 30 minutes. I received the report 7 days later, along for recommendations to contact either a roofer, a waterproofer, or a contractor to clean the drains and drainage pipe. It cost $500+. I replied, asking why this would not be more appropriate work for a plumber. No answer. I also wanted to understand the relationship between the tests and the recommendation. Most of the report was full of boiler plate language. No explanation for the relation between these tests and the recommendation was forthcoming, just: "That's what we concluded." Of the 2 recommended service people, one (the roofer) called me back. He confirmed what I suspected: cleaning the drainage pipe is a job for plumbers, not roofers. So I called Roto-Rooter to clean out the drain pipes. It has helped but not completely. I thought initially that the owner was a nice guy and would have considered hiring them again, but then I received a patronizing, passive-aggressive reply suggesting that I had voided my warranty by posting an honest review. I am disappointed by JPD's lack of professionalism and inability to communicate clearly and kindly. It says quite a bit about his judgment that he would post such a reply while admonishing me for not contacting him privately. read more

I contacted JD Diagnostics for a leak issue that our contractor tried to solve for months. Jarrod from JD Diagnostic has been extremely helpful identifying the source of the leak, but also was extremely efficient, professional and responsive. He really took the time to explain the results and even help us to find the right person to do the repairs. I would highly recommend their service and keep their contact info for the futur. read more

Don't do anything with your leak until you call Jarrod. We wasted thousands of dollars "fixing" our leaks to no avail. Once we found Jarrod he found the leaks and prescribed the repair. We haven't had a leak in that area since! We have had other leaks, (typical for NYC new construction), and Jarrod has come to the rescue every time. Stop wasting your time, money and mental health trying to find the source of your leaks. JP Diagnostics will get the job done competitively and correctly. read more

JP is a life saver. He's been to our house twice now, once for the basement, and once for a leak over the front door. The first time JP came over, he spent over and hour examining and photographing the basement, then got back to us 2 days later with a thorough report. Since it was a complicated issue, he came back to our house to explain the issue in person, patiently answering all our questions until we understood exactly what was going on. Having the report was so helpful- we could send it to contractors so they knew exactly what the problem was. No needlessly tearing apart the house to try to find the leak. The second time, JP came over to check out the front door, did a thurough examination, and got back with the report quickly. He even recommended a couple contractors to get quotes from. When the initial fix didn't work, he came back free of charge, met with the contractor and me at the house, and continued to problem solve. JP looks for the RIGHT solution, not the most expensive or the easiest. He's also great to work with- arrives on time, responds to email quickly, and stays with you until the problem is solved. I recommend Jarrod to everyone I meet who has a water issue. read more

M Coaxum I have a leak in my condo apartment in three different places. The leak in my unit is off and on. Jarrod came in and took pictures of my entire apartment. He was very courteous, professional and showed empathy for my plight. During one of our hurricanes this past summer, rain was coming into my apartment very fast. I became upset and called Jarrod that Saturday. Nia was kind enough to inform me that the report was sent to me the day before. The report showed several origins of what could be the source of the leak and several repairs that needed to be done. Jarrod was able to conclude his findings, even though he didn't have access to the unit above me. Jarrod decided to come back to my unit, after my phone call that water comes while raining. I appreciate this gesture to add this component to further investigate what could also be going on in my apartment. Jarrod hasn't made the visit yet, but I am quite sure, all will prevail, thanks to J. P. Diagnostics. read more

JP is very nice, he overbooked me by mistake and agreed to see me the next day, at the time of my choosing. When he came to the house he was very informative. He gave me two referrals to fix my roof. One referral I could not get a hold of, so JP gave me a third one to choose from. I ended up choosing William Liang in Queens Village. I am very satisfied with both men. I feel they were honest and fair. I would definitely recommend JP and William to others. read more

Jarrod wrote that my review was written by a former employee. That is a lie. I am not a former employee but an owner of an apartment in a building in Brooklyn. He walked off the job after being challenged for what he later acknowledged was his own mistake. read more

Jarrod from JP Diagnostics has been extremely helpful identifying the source of a leak that we've been contending with for over two years. Multiple roofers and contractors had misdiagnosed it and suggested spending thousands of dollars on solutions that we know now would not have solved the problem. He has continued to follow up and provide advice as we've dealt with contractors to fix the problem. If you have leaks without an obvious source I would definitely recommend getting JP diagnostics to do testing before spending money with a contractor who will just say, "you need a whole new roof." read more

I wish I could give more than 5 stars! Jarrod at JP Diagnostics helped me pinpoint, to the exact location, the source of a leak that I have been dealing with for years. I only wish that I had known about him sooner. It would have saved me years of headaches, and contractors, and damage. Jarrod was professional and responsive. Even after he completed the job, he was helpful and always took my calls and emails when I needed his advice. Thank you Jarrod! read more

We reached out to JP Diagnostics on the recommendation of a waterproofing contractor who we had come out to look at our home, which needed to be waterproofed. Jarrod has been terrific to work with - prompt, honest, and very helpful. We realized the extent of the issue with his infrared analysis, which has been instrumental in helping us to determine where to focus the repairs. We haven't yet embarked on the repair process, but he has assured us that he will be available to help. We had two options for his service - either pay leak by leak or do a whole-building package. We went with the latter, which also comes with a two-year warranty, which gives us peace of mind to know that Jarrod will come back to re-scan if necessary after the repairs have been done, to make sure we don't have any further issues. read more

We've used JP probably half a dozen times, and the recommendations have generally been on the nose. They will guarantee their work, as well as help out in overseeing contractors to do the work that they recommend. I've referred them to a few colleagues as well. read more

I'd just moved into a new house and had water coming into the basement from no visible point of entry (which was of course utterly disconcerting). Jared responded promptly to my call and guided me through the process of how to effectively solve the problem over several follow ups that made me feel like I was his only client. JP's services and technologies are a miracle and while I hope I never have problems with water again, I'll certainly be calling Jared and JP back if I do. read more

We've had a leak in our roof above our living room and the roofer performing the work couldn't find the leak when trying 4 times. JP diagnostics came by and the leak was found immediately and we were able to remedy the water infiltration in our living room. JP Diagnostics is very professional and reliable. We would highly recommend there services to anyone with a water issue. You'll have complete confidence and satisfaction when hiring them. read more

I called JP Diagnostics to locate several leaks within my unit in Williamsburg. They were on time and efficient with their findings, helping solve the problem and removing the guess work to where the water leaks were coming from. I would definitely recommend them in the future. read more

This company is AMAZING. I have lived in the same 9 story brick condo building for the last 18years and we have ALWAYS had water leak issues. Every year we replace roofs, remove decks, seal cracks, seal bricks ... etc ... always in search of the magic repair that will stop the leaks. And after every nor'easter our building is flooded again! I was introduced to JP diagnostics and after a couple of photo imaging sessions I was astonished to realize that we have been repairing the wrong areas! With JP's technology you can actually SEE the water entry point and identify the source of the leak. I now know that we have wasted thousands of dollars by constantly repairing the wrong issue! I will never make another waterproof repair without getting a JP report first. Not to mention that the owner of the company, Jarrod, is so knowledgeable about his subject AND truly the nicest person you could ever hope to meet. Words cannot express how impressed I am with this service and so thankful to have found it! Thank you Jarrod!!! read more

I've personally recommended Jay at JP diagnostics to over a dozen customers of mine, as the owner of Royal Renovators Inc. a roofing and siding company. When we can't find the leak, we call JP. A previous customer of ours had received an infrared report from JP and sent it to us for help fixing the leak discovered. I and our team were so impressed by the level of detail of the report, where the water was coming from, which direction it was traveling in, and JP incorporates his own knowledge to give advice on whether it's the roof, or masonry, or what. So it's not just a thermal imaging report, it's that plus advice which is a huge premium. For a few hundred bucks, you'd be penny pinching and stepping on your own toes to not call JP to find and diagnose a leak before hiring a contractor, unless you believe the leak source is so obvious or you want a full replacement of the area. JP comes out himself to personally do the infrared test, he doesn't hire others to do the on site work while he secretly possesses all the knowledge and experience. If you call and he doesn't answer, he may be on site, if you want his services leave him a voicemail. JP contributes enormously to the waterproofing industry in our region, NYC metro area, and he deserves every one of 5 stars. read more

I cannot recommend JP Diagnostics and Jarrod enough. Extremely professional, thorough and punctual. He was able to diagnose the issue with extreme accuracy and then provide a detail report. I will use JP for all my leak detection issues in the future. read more

I've lost many countless nights of sleep worrying about where the leak in my wall was coming from. I've had many contractors come in only to leave not wanting to take the job because they weren't confident where the problem was. I found Jay on Yelp and boy, was he a life saver. He was able to tell me not only where the problem was, but also how to remedy it. I wish I had found him sooner. If you have a stubborn leak, JP Diagnostics is your answer. read more

Jarrod, the principal at JP Diagnostics, was a picture of efficiency and determination to get at a solution to basement window water leaks in my Brooklyn townhouse that had vexed me for two years. He combined expertise in thermographic imaging with a can-do approach to identifying contractors to waterproof the vulnerable areas which showed up in the images. He pointed me in a very specific direction for a solution, while waterproofing contractors had recommended only the expensive approach of process of elimination. I would recommend him highly. read more

This is the best service. I would of spent tons of money trying to find where these leaks were coming. I'm so happy the only thing I did was call Jarrod. It's the best money ever spent. I now know exactly what has to be done. He even referred someone that can help fix it. Jarrod was helpful, clear, on time and I would strongly suggest before trying to figure this out on your own, call the experts. read more

I called JP Diagnostics to detect a leak in my community. The community is not large. He came out a few weeks later and did his test. A few days later he sent a very detailed report as to where the leak is. I hired a contractor to repair the leak. When the contractor came onsite, they found the leak to be over 100 feet from where the leak was reported to be by Jarrod of JP diagnostics. When I reached out to Jarrod he got real defensive and unprofessional. He feels he completed the job, he did provide a service but unfortunately he did not pin point the leak we were looking for. He asked me to email him and he said he will speak to his partner to see if they can do anything for me. After multiple emails and phone calls he has not responded back to me. Two weeks later and still have not heard anything. I don't usually post on here but Jarrod's unprofessional approach and the fact that he could not detect a leak 3 feet away from where the water was coming out of the ground has me on here. read more

Jarrod has inspected our coop building and done an excellent job. He accommodated our schedule, answered numerous questions via email, and issued a detailed report. We can highly recommend him. read more

JP Diagnostics should be the first call for any leak issues. My experience with Jarrod has been top notch - thorough analysis, on time for appointments, easy to reach and communicate with, and patient with explanations. I would highly recommend JP Diagnostics and again, they should be the first call. It will end up saving you money, time, and frustration. If the need arises, I would definitely use JP Diagnostics again. read more

We were purchasing a 2-family house in Brooklyn but were having doubt around the basement foundation water leak fix the seller was supposed to take care of. The stained wall and skirting boards were painted over just 2 weeks before closing and it was needless to say very difficult to judge whether there's an active water leak or not by just looking at it. We brought in JP diagnostics - Jarrod is excellent, accommodated to our last minute needs for the assessment (literally one day prior to closing) and used his non-invasive toolkit to take infrared photos in all questionable areas. His report put us at easy going into closing and helped us with our negotiation greatly. We would highly recommend them. Jarrod is super friendly as well and he even followed up on closing day to see if we had additional question to be answered and wished us good luck closing!! Any future water leak issue to seek source, we'd not think twice and would use him again. read more
