There is such a difference when you have a plumbing company do your work and amateurs or do it yourself. Sometimes there is a short wait but it is worth it. Everyone is very friendly aside from being professional. read more

Outstanding customer service. Excellent work - so professional. They were thorough in diagnosing our issue and did a great job on the repair. read more

In the middle of a freezing cold winter, my pipes froze and water was leaking into my dining room. The woman that answered the phone and set up the visit was so sweet and kind. I think she could tell I was freaking out! Carlos came. He was one of the nicest people that has ever come to my house. He explained every single thing to me, twice, since I know zero about pipes and plumbing. I hope I never have to call an emergency plumber to my house, but I'll be calling them for any issues I have forever!!! read more

Our water heater in the basement failed on a Friday and the Stimmler team responded promptly, helped us decide which replacement heater to use, and by Saturday afternoon we had a new heater in place and fully operational! The crew was very professional and courteous and we recommend Stimmler highly. read more

Andy and his crew installed a new HVAC in our home. Everything went great and it was effortless on our part! crew was professional and courteous and they cleaned up afterwards. we have used Andy for other plumbing jobs and all were done to our complete satisfaction. they are a family owned company in business for years and I would highly recommend them. read more

Always responsive and friendly. Honest and dependable family business. I had them do a lot of work in my home from HVAC and plumbing. I wouldn't go anywhere else read more

Spoke to two people who confirmed they had availability in the afternoon to come fix our boiler which failed in the middle of the night. This was great because of the short notice and we were happy to have it fixed The afternoon comes and they didn't show up. Nobody called to let me know. I called 4 separate times, left a message and no call back. Didn't even bother to call the following morning to reschedule. This was GREAT because I had told other companies NOT to come because I was EXPECTING Stimmler. So, instead of a morning without heat, we are now on day 3. How hard is it to call someone back just to let them know?? Was it really too much of a hassle to have some common decency? If their communication is any testament to this companies work I don't suggest even attempting to call them. Because it seems like they honestly don't care. read more

Don't do business with this company. They misdiagnosed my heating issue, caused me to take several days off work and then tried to charge me for something no one told me about up front. Had to get another company to come out (Summers Quality) that correctly diagnosed the issue and took care of it quickly. After disputing the charge with the owner, he proceeded to make a claim to impact my credit. read more

We have a Bosch tankless water heater, that was not working intermittently. We call Bosch and they asked that we call one of their local certified technicians. Of all the Bosch certified technicians GJ Stimmler was the only one within the right radius of service and were able to come. Andrew Stimmler, on the first visit came and opened up the heater to diagnose the problem and had to call Bosch to troubleshoot it. After 3 hours of troubleshooting he told me that after talking with Bosch, I needed to change some parts which he already told Bosch about, and I just had to call Bosch and pay for it, which I did right away. He closed up all the parts and I noticed that he didn't connect the water connection back to the unit, and when asked he just connected it back without any explanation and left. Issue 1: After he left, I opened a faucet in the bathroom and the hot water heater started leaking all over!! When I called him back he didn't respond for a long time, and finally after sending a video of my leaking "like a waterfall" unit, he finally told me that while opening up the unit, the "o-ring" broke the seal, and tried to blame me for asking him to connect the water back on (even though he never explained to me in the first place why he wanted to leave the water disconnected or that he broke the o-ring seal during diagnosis). He refused to come back to fix the problem and just gave me instructions on how to disconnect the water from the unit and put a bucket underneath to collect the leaky water!! I had already paid him for 3 hours worth of work, and now I had a leaky unit with a bucket underneath!!! He refused to come back to fix it that day or day after, and said he would come only after the parts arrived. Issue 2: After the parts arrived, we scheduled a day for him to come replace the faulty parts and fix the unit. He doesnt come himself but sends 2 of his employees, who arrive about 2 hrs late without as much as a courtesy call to inform me they were delayed or arriving late. Once they arrived they informed me that the parts that arrived were the wrong parts!!! Mind you, Andrew and Bosch made the call on what parts were ordered, and I just called in to pay for it. When I made a comment that, between Andrew Stimmler and Bosch they had to figure it out, and get the right parts, he said what I said was offensive and quit the job!! I had to call again to beg him to tell me what the right parts were so I could call Bosch to order and find some other plumber to fix this!! So, he basically caused my water heater to leak, didnt tell me about it, worked with Bosch to order the wrong parts and then quits because I had the "audacity" to call him out on his mistakes!! Now I am stuck because there is no other plumber who is knowledgeable of Bosch Tankless Heaters within my service area. I have to now look at options to replace my entire unit!! Andrew Stimmler is a blight on any honest, hard-working plumber and please avoid him at all costs!! read more

Our water heater kept leaking and it slowly started to become worse, so we called and a very friendly lady answered the call and coordinated Andrew's visit to check out what's going on. It was clear that we needed a new heater and two days later, his crew showed up and replaced it. This was probably one of the most hassle-free experiences I have had so far, the work was done excellently, the pricing was good (the lowest estimate in the area) and the staff was friendly and respectful of our interior. I'll definitely recommend Stimmler G J & Sons to friends and family! read more

I live in Baltimore but have a rental in Philly. I need a plumber a friend recommended Stimmler and Sons I am very happy they did.

Amazing! Broken water valve (the main) leaking into the basement during the shutdown due to the Coronavirus! Stimmler to the rescue! Within an hour of my initial contact with Gail, Jeff and James were here. From accessing the curb box to the replacement of the broken valve, there was nothing simple about this job. Yet, Jeff and James got it done. Want to personally say thank you again for working though all the obstacles & getting the job done on this miserable day! Every representative I dealt with today was professional and courteous. (And the price came in lower than expected! How often you ever hear that?!?!). Thank you Jeff and James & Stimmler Plumbing & Heating!! read more

What a rip-off! Do not use this plumber. They installed a new toilet about 1-1.5 yrs. ago. I called them because the base was wobbling - not even a year old. I called again because the toilet runs for no apparent reason, but I can count on it to run every time I sit on it. They came by and refused to repair because the one year guarantee had expired. They do not stand behind their work and customer service is horrible. WOULD NOT RECOMMEND! read more

Been using this company for years since Andrew Stimmler's father used to run the business and after he passed away. Just had another hot water heater put in after the previous one leaked after 8 years which is normal. The replacement hot water heater that Andrew Stimmler put in does not make enough hot water. Since 1971, we have had a 40 gallon Bradford White hot water heater serve our house always providing enough hot water. He will not stand by the warranty and do the testing for the company. He says that he is "Out if the loop." Bradford White does not come out and do any testing. They require the installer to do it. After all these years using this pluming company, they have let us down. "Buyer Beware." read more

Bought a house and needed the furnace/boiler checked prior to the winter season. Was also having some issues with the system in general. I called the company that had serviced the equipment for years (The previous owner had highly recommended) and they no showed on me twice but called me back to see if I wanted to buy a service plan. (!?!). That was enough for me. I started the hunt for a new Heating guy. Out of desperation I asked a friend for a referral and she recommended G.J. Stimmler and sons. (She raved about them and how honest they were) I'm very happy that she referred them. In no time, I had the owner Andy and his assistant on my doorstep and the furnace was being cleaned and inspected. They identified the cause of my problems and replaced an electrical part. The bill was very reasonable and I never felt like they were rushing to get to the next job. This is a local, family owned company that's a couple of generations in the making. I can see why they have endured. The entire time they were working, Andy answered my barrage of questions about hot water heating systems in general and my 36 year old boiler in particular. I asked when it should be replaced. Clearly, there are no high pressure sales tactics here. I was told my system is past it's normal "useful" life of 30 years but that it's been very well maintained and does not look it's age at all. He said it was a coin toss and that the boiler could last for a few years more or die in a few months. There's just no way to know. He simply suggested putting money away as and when I can and planning for a new system down the road. On top of that, when I asked him if he knew of a good tree service, he gave me a name and number that worked out fantastically. What sealed the deal for me was about a month later, I called the emergency line because my furnace went out. Andy diagnosed the problem over the phone based on my description and told me what to do. Heat restored. Zero charge. These are the only guys I will use from now on. I cannot recommend them enough and I see their truck in the neighborhood a couple of times a week at least. Irrelevant but interesting - I recently looked at some of the yellowed paperwork and instruction sheets that are tacked to the basement wall near the furnace. (Most pamphlets are for equipment long since removed but they date back to the early 60's.) These documents were added to over the years by Obsessive owners as new parts were installed/equipment replaced and they have apparently remained untouched for decades. Being a history nerd, I took them down and sifted through them and discovered that my boiler was installed (in 1980) by none other than G.J Stimmler and Sons. Irony! That just gives me warm fuzzies. One generation of a family business installed the equipment, the current generation will (eventually) take it out and replace it. Full circle.... read more

These guys (and the lovely woman who answers the phone) have helped me in several, separate plumbing crises over the past year of owning my new house. Each time I've called, they've been prompt and thorough. The guys always take the time to explain to me what was happening, how they were going to fix it, and what it would cost. I feel extremely confident in the work they have done. Having plumbing scares as a new homeowner can be exhausting, but I feel grateful to have Stimmler and Sons as my go-to plumbers. read more

Heater malfunctioned on the coldest night of the year (1/7/2018) and called Stimmler and Sons. They got back to me within 10 minutes. Andrew came out and quickly diagnosed the minor problem and had the house warm in no time! I would recommend Stimmler and Sons to everyone. read more

After reading a few previous reviews, I decided to call Stimmler GJ & Sons. The woman who answered the phone could not have been any kinder - and I received a return phone call within the hour AND Andrew showed up almost immediately. My son is in the process of buying his first house - and Andrew could not have been any more informative, patient and thorough than I would hope for someone to be- explaining all of the plumbing and heating issues. NEVER did I feel pressured to do any work, in fact, he was so honest, he told me I could wait and handle a few small issues with a trip to home depot! If honesty is an important factor in hiring a plumber - call this company. read more

Let me start by sayng anyone who does NOT call Stimmler & Sons for their plumbing issues is foolish and missing out on what is truly the most IMPRESSIVE all around "service" experience I ever had. Let me start from the beginning. Andy Stimmler called back within hours of my online request for a free estimate. He even called 2x after hours/on a weekend. Andy was pleasant, kind, and readily available to come out and check my issues that had been deemed "severe and unfixable without tearing out the entire bathroom" for multiple years. Countless other plumbers (and friends who know plumbing) over seven years ALL told me I had to tear out my entire bathroom and pay upwards to $10,000 for the plumbing and reconstructing the bathroom, and that didn't even include new bathroom items or any upgrades. And I would not and could not do that financially or otherwise for multiple reasons! But the problem got to a point where we were showering in water up to our calves/knees and the tub wasn't draining for hours. It was no longer tolerable! So I prayed...and contacted Andy's. We made an appointment for a few days later flexible to my schedule. Andy called ahead with a reminder and showed up on time to evaluate my multiple plumbing issue(s). He was informative of all possible scenarios, he outlined all things he would "try" and all things that COULD happen and how he/we would handle it on each level. It was so obvious he was going to try every single thing possible to avoid any major home changes or outrageous bills or even home owners having to get involved. For the first time in years I felt confident it could be fixed and that someone would "spend time" really trying to FIX the issues rather than just say "this is really bad and you just need to rip out your bathroom" and get every cent they could to fix the problems. Andy said "This could be bad and could be worse than even I know, but I am going to do anything and everything I can as if it were MY OWN HOUSE to make sure it is the fastest easiest and least expensive fix for you". As if this wasn't enough, before leaving he even checked out my heater and hot water heater and gave me a lot of helpful tips/advice! We set up a date to start services a few days later. He even rescheduled at my request without issue when I had a family emergency. The day the work was to be done, Andy called ahead and arrived on time with several trucks of men. They came in and started laying tarps to protect my kitchen from dirt debris and possible water. Over the next few hours I tried to hide...but I did hear a few things. I heard Andy say to his guys something was way worse then he thought but he was going to really try everything he could. I heard Andy say some part was in a bad spot and way harder than he expected. I heard Andy say he was almost at the end of trying things and he was going to try one more thing despite thinking it may not work or would cause awful damage as a result of fixing the problem. Well guess what...IT WORKED! Now, the work may have resulted in a pinhole leak...or the pinhole leak wasn't already there. So then the guys began working on the pinhole leak. They worked on it for a long time, then added a chemical based goop that hardened like concrete to seal the leak and prevent continued/future leaking. They waited to test it repeatedly, and then two guys came back hours later to retest it, clean up again, and test water, drains, pipes again. In fact I even called after them after they left because I saw water in the tub and thought there was an issue but it was my mistake. The guy came back in and stayed long enough to show me over and over how amazing my drain worked and how all the issues were fixed. Not only did they fix all the problems previously told nothing could fix the issues short of tearing out the entire bathroom, but they also upgraded to PVC pipes in the vicinity of the problem area to help prevent future issues. Now if ALL that is not enough to make you use these guys...then came the bill!! I don't feel comfy sharing the bill but I will say after quotes of $8,000-10,000 by tons of other plumbers and that was only to fix issue and rebuild bathroom...THIS bill was exactly 96% lower to the penny!! YOU DO THE MATH! Needless to say, I am BEYOND thankful and impressed and a loyal customer FOR LIFE. I will tell anyone and everyone to call Stimmler's!! I have already posted two huge shout outs on FB and sent out mass email/texts telling people they MUST call Stimmlers...end of story! I literally cried while they were here and when they left and saw things worked!! I couldn't believe the time energy and effort they put in to fix issues NO ONE could/ would fix for SEVEN years!! So many dif plumbers came out and so many friends who know plumbing came out. EVERYONE said unable to fix or must rip out entire bathroom. Stimmler's ripped out NOTHING!! #TEAMSTIMMLERS read more
