I needed a new sump pump for my crawlspace, and I wanted quotes for a moisture barrier. I received four quotes: one high, one low, and two in the middle. I went with a middle quote, E-Mora Construction, and I'm so glad I did! I was anxious for the sump pump work to be completed before the rains began. Although E-Mora Construction had a full schedule, they managed to squeeze me in and completed the work ahead of schedule. The workers were great, and tidied up after work finished for the day. The sump pumps and moisture barrier were installed in two days. Ernesto Mora himself came to offer the initial quote, and returned once the work was completed for a final inspection, and to collect payment. When my electrician went into the crawlspace to install a dedicated circuit, he came out and said that if it were his house, he'd be "very happy with the work, and I've been in a lot of crawlspaces!" read more

Ernesto is a true professional! Came out to inspect the sump pump situation and provided helpful suggestions. He honored his warranty on his job with no charge. Will be calling him back in a few months to do a proper crawl space clean out and drainage. read more

Reached out to check availability in order to decide how to move forward and got a bit of attitude. Have to provide phone number and address to even talk to me. No thank you. UPDATED from 1 to 5 stars - Thanks to Ernesto's reply, we talked again and he came out for a quote. We haven't received the quote, but he was very detailed and gave us a lot of great tips. He seems very responsible and we were probably too harsh in the initial review. Will update the review as our experience grows. read more

Just phoned E. Mora Company from seeing ad on yelp. needed information on my laundry room water leak. I talked to Ernesto, owner... Blown away by what a gentleman he was and the information he gave me . He was totally honest and up front with what the problem was --- 99% and what to do. He Said not that big of problem and to just get my plumber to put in a sump pump. He said he would be happy to do it but being I have a good plumber already that knows sump pump installation his company is in Dublin I'm in Pacifica. He said he travels all over but just go with my plumber. I now have an appointment with my guy to install sump pump! Bottom line is Ernesto was "Not " a Dollar Hounddog! A integrity honest guy !

I'm a long-time sump pump installation & maintenance customer and E Mora also covered our dirt crawl space with thick sealed sheeting -- they do AWESOME work! read more

Worked with Ernesto and team to install two sump pumps and a moisture barrier in crawl space. Ernesto was very helpful, explained what was needed and overall I thought offered the best value compared to other crawl space companies in the area. We opted for the 20ml thick barrier and his team were able to fasten securely to the foundation walls despite our crawlspace having limited access space in places. Pumps were fitted with water alarms and hooked up to sub-panel by Andy (Anaya Electric) who Ernesto recommended and was easy to schedule with. Overall very pleased with the work done and excellent customer service. Work is also backed by solid guarantees which are better than competitors. read more

Ernesto is one of the remaining business owners who takes his work and words seriously. We had an issue where crawlspace gets flooded with water whenever it rains, tried multiple companies and estimates with limited success. Ernesto came over provided an estimate for sump pumps and draining (it was expensive) but it did fix the water issue. As any project there were hiccups along the way and even warranty work, Ernesto and his team always followed through to come over and ensure the project is working as expected read more

We recently worked with Ernesto and his team to do some trenching work and install sump pumps in our crawl space. From the initial estimate until inspection, everything was perfect. Ernesto is fair, honest, and communicates and sets expectations clearly. The work was completed early, with everything spotless and quality focused. We would gladly work with E-Mora Construction again and would highly recommend them to anyone considering crawl space work. read more

Ernesto and his team always do a great job! They did a nice moisture barrier installation and recently came back to swap out the sump pump for something different that I wanted. read more

Really glad that I had Ernesto and his team come out to waterproof our crawlspace. Problem we had: Our area has a high water table. When we first moved in, we noticed taht even with a slight rain, there would be an inch of water covering the entire crawlspace. We were living on a lake. Estimate: Ernesto came out to do an estimate. Compared with others we asked, he was more thorough and went through the entire crawlspace area that the competitor's hadn't checked. I really appreciated that he was able to show us photos of what was going on under the house. He showed us the residual lines left by water in all corners of the house. It's tough work belly crawling through a concrete crawlspace! Proposal: Ernesto was able to price match other estimates we had gotten from competitors. We ended up getting 3 sump pumps and thicker plastic covering. He showed us a schematic of how he was going to place the sump pumps strategically to drain low areas in the crawlspace and also how he was going to tie all the sump pumps to an existing french drain going into the street Project: The team did their work within a week. Ernesto was communicative through the entire process and easy to reach. His team doesn't do electrical work, so we hired their recommended electrician who was also very thorough in their work as well. Result: Ernesto stands by his work. You get a signed 5 year warranty for the workmanship. Now that the rains have come, looking into the crawlspace, it's nice and dry. Also, when one of the sump pump water level alarms went off, Ernesto was able to diagnose the problem quickly. Very happy with the results! read more

If you're looking for a company to install a sump pump in your crawl space these guys do an excellent job.

E-mora Construction was excellent to work with! In both quality of work and communication with the staff and team. I have had water entry in the basement since we purchased the house. The team came in and implemented a basement drainage, moisture barrier, and improved sump pump configuration. We're several rains into this season and the basement is dry! Thank you Ernesto and team! I'd also like to add that they were flexible as well. I had a piece in which I wanted to pour fresh concrete to improve stability, and he was willing to pause the job and come back later so that I could have a more robust basement solution. Highly recommend! read more

Ernesto came to my house all the way from Merced to repair a sump pump that I thought was broken and I thought needed to be replaced. He said I did not need one. He inspected it and gave me that recommendation. Now that's a first I've had a recommendation where somebody was not trying to upsell or hustle me.. I took him underneath the house he climbed under and gave me some tips on what I'm supposed to do to call a handyman for a very small job and not a plumber to fix some rubber hose down there. because it will be too expensive if I used a plumber. If ever anyone needs a sump pump repair or installation this is the guy. Honest And very knowledgeable. He knows his stuff. Thank you Ernesto.! read more

I called Ernesto asking for a quote for fixing foundation problems of a potential home purchase. Ernesto was very generous with his time and walked me through the whole process. I would definitely recommend him to my friends and families. read more

How did I never write a review for Ernesto? This guy is 100% solid, knows his business and does impeccable work. My crawl space was a muddy dark horror show. I did have some clown before him "seal my crawlspace". It was a complete joke. When Ernesto and team were done, you could almost move in under there. Glistening white and not a smudge of mud. I really don't know how he did it working amongst all the dirt and mud. And, in the years since, I've occasionally had questions about the crawl space, some related to his work and some unrelated. And this guy responds immediately over and over again and stays on the conversation with me to fix my issues and provided great help. The best in the business. read more

We hired E Mora's services to seal our crawlspace after it got flooded during last year's heavy rains. Their crew is booked months in advance. However the wait was worth it. We are happy with the service and our crawlspace is transformed from a stale and dusty space to clean and sealed. They charge for the initial inspection but it is worth it as Ernesto saw a couple of unrelated issues with our plumbing and informed us. After the work was done he walked me through how to maintain the sump pump. Ernesto is one of those rare guys who will exceed your expectations. Recommended without any hesitation. read more

E Mora Construction installed two sump pumps and a vapor barrier in our crawlspace. From the very beginning, it was a pleasure working with Ernesto. He is the real deal - a truly honest small business owner who has the best interest of his clients in mind. He took the time to explain to me what the issue was, what was needed, and did not try to oversell me on anything. E Mora's prices were very competitive and the quality of work was top-notch. Furthermore, it was very easy to communicate with Ernesto throughout the entire process. He always promptly got back to me. I highly recommend Ernesto and his team. read more

Our contractor recommended Ernesto to install a moisture barrier under our house. We are very satisfied with the workmanship. He's An expert with everything related to crawl space. He provided several suggestions to prevent future water damage, broken pipes and animal infestation. He identified problems we never knew about and recommended the appropriate steps that we should take. I never knew we had a massive void under our garage floor until he found it and suggested we fill it. I highly recommend using him. I wasn't home when his crew did all the work, but I'm still so amazed by how quickly they finished the job in such little space. read more

Really good service, quality work and very responsive. They really cleaned up our crawl space and made it so much more pleasant. Replaced sump pump, and provided periodic inspections. Really useful during all the storms this year. read more

Ernesto, Hector and Louis were all professional, friendly and prompt. The work was top notch and performed quickly. Our crawl-space is so much nicer and more useful now, and the air quality inside our house should be healthier for years to come. read more

When I discovered I had flooding in my crawlspace, I was overwhelmed by all the different recommendations on how to remedy the problem. I am so grateful and blessed to have found Ernesto E-Mora Construction! Ernesto is exactly the type of person you want to do work on your house. He is trustworthy, thorough, and knowledgeable. He was quick to respond to my initial inquiry and after his visit I didn't even schedule any other businesses because I was sure I only wanted to do business with him. Even though I had to wait months to get onto his schedule, it was worth the wait. His crew is considerate and hardworking. They installed a sump pump and vapor barrier. Ernesto did a lengthy inspection with me afterwards and taught me so much about my own house! Ernesto & his crew are reliable and dependable. They stand by their work - and so far everything has been working well! I know that if there are any questions or concerns in the future, that Ernesto & the company will be there to help me. read more

E Mora did an interior basement French drain for me a few years ago, because we always have floods in the basement whenever there is a heavy rain. His work proved to be excellent because this year, with the storm and flood everywhere, my basement is dry!!!! So this is a long overdue review for him. Thank you, E Mora! read more

Quickly were able to come out to our home and install a temporary sump pump to get the existing water out from under our crawlspace. Later that week they then came out and installed a permanent sump pump and ran drainage lines to the pump under the home to capture any water that might flow in from any leaks that might occur again. read more

We loved working with Ernesto! We had a damp crawlspace and were looking for ways to fix it, and Ernesto did a thorough inspection of the whole crawlspace and explained everything he saw. He was very honest about what wasn't a big deal and what should be fixed sooner rather than later. It was very low pressure and helped us understand our situation better. We went ahead and had him and his team install another sump pump and a thick moisture barrier in the crawlspace, which they did pretty quickly. Anyone who's had to go into our crawlspace now with the new moisture barrier is always very impressed with how clean it is! Ernesto has also been very responsive to any extra questions I've had afterwards. We're hopeful going into the rainy season that this solution will help us keep the crawlspace and our house drier and healthier. read more

Responsive, serviced one sump pump and diagnosed/replaced another. Efficient, responsive and reasonably priced.

I would highly recommend Ernesto and E Mora Construction. They are extremely knowledgeable and very professional. Ernesto explained to us exactly what was needed to protect the crawl space of our home in Moraga and prevent moisture damage in our crawl space! He spent considerable time explaining the best way to fix the water issue. He was able to fit me in my schedule and provided a lengthy inspection of the home! I would definitely recommend him!!!!! read more

Parade of Storms Update: Happy to report that I peeked under our house this week after the Parade of Storms was over, and our crawlspace is still dry. I recommended Ernesto to my mother in law, who lives at the foot of Mount Tam and used to have a flooded crawlspace and basement every other year. Also still dry. Thank you Ernesto! I only give reviews if I think something is awesome, or terrible. Ernesto is awesome. Highly recommended! read more

Very happy to have E-Mora installing vapor barriers in my crawl space. I have wireless humidity sensors in the crawl space and noticed that the humidity was down from 85% to 62%, it really works! The crawl space is clean and healthy now. Besides vapor barriers, E-Mora reset the sump pump which was improperly installed by another plumbing company in Mountain View. They also installed a new pump in another side of the house, then rerouted the pipes to drain the water to the street. All the work was done in high quality and I'm very satisfied with. The owner Ernesto is very knowledgeable and definitely knows his stuff. He walked with me after the job was complete to make sure everything is done in the right way. I highly recommend E-Mora if you have moisture problem in your crawl space. read more

So, this is the very first guy that did the review of Ernesto and EMora Construction. We had record rains yesterday and our alarm went off in the crawl space. For those of you who are wondering if this really works after 10 years the answer is yes! First time ever the alarm went off and we have never had a problem with our system that Ernesto put in our house. I think he will be the first to tell you that our house probably ranks in the top 10% of worst homes with flooding go on in their crawl space. Super responsive even now after all these years. Long story short that it wasn't anyting wrong with what he installed. The pumps leading into the drains seem to be clogged. I need to snake out the drain and that will more than not do the trick. What did his team do? They actually built a temporary drainage system for the water to be sucked out of my attic. Ernesto and his team are the real deal! They really are like family. I don't question anything they do and there are so detailed in everything they do. Can't imagine why you would ever go to anyone else in regards to the speciality business. read more

Ernesto from E-Mora Construction did a excellent job installing sump pumps in my crawl space. They are full automatic, including battery backup. I can see their status on my phone and I get an email if there is any problem with them. A terrific job done on time and at a competitive price. read more

Called early this year to schedule an appointment. They fit me in their tight schedule. Ernesto showed up and gave lots of helpful maintenance tips and things to look out for. He knows his stuff and is extremely willing and helpful on sharing his insights and advice. He was honest and said We would not be needing his services. We will definitely use him again to help inspect other future properties. Just like all the other reviews, he is absolutely fantastic. As a property owner, you always want a list of professionals you can truly trust and rely on, contractors who do honest good work and go above and beyond in their job. He is absolutely someone I intend on working with in the future for general property inspections and water issues. I highly recommend them and will be happy to refer them to anyone who has moisture issues. read more

From start to finish this is a excellent business!!! Ernesto knows everything about Crawlspace sealing there is to know. They keep you informed and do excellent work in a timely fashion. The enclosed Crawlspace has completely changed the comfort level of our home !! It's so much warmer and drier Thank you Emora Construction!! Awesome job!!! read more

I'm very happy with E Mora Construction's work with regards to my crawlspace. They were very communicative and respectful during their time working underneath the house. They kept everything clean and they always cleaned up after they were done for the day. I wish all contractors are like E Mora when it comes to caring for the whole house. They thoughtfully protected every part of the house which got affected by dust. They also worked proficiently. It was like clockwork. Now, my crawlspace looked clean and organized. The sump pumps work well. I know I'm in good hands. I highly recommend E Mora for any crawlspace encapsulation work. read more

I was shopping around for crawlspace encapsulation. I have called other places that come out and do crawlspace inspection to decide what I need. Most guys come out and do a free inspection. E-Mora claimed that they do 'free' inspection but it is actually not the case. They want $200 upfront payment to come out. Although they said they would deduct the money if you decide to use their service. But you would be running the risk of loosing your $200. After back-and-forth emailing finally they told me it would be about $4-$5 per sqft. They may or may not provide better service than other places and they claimed that they use 20-mil material which is usually an overkill. I'll suggest to look the other way. read more

I waited to write this review to see how their fix for our constantly leaking basement is working. It's working perfectly. The next Test will come when the rains start up. (Our house is on an underground creek). If the system E Mora has installed isn't enough to handle the increased volume then they will come back and add to the original sump system. Their prices are so reasonable I won't mind paying for them to come back. Taking this wait and see approach shows great integrity on their part and keeps prices low for the home owner. I must add that the workers and the owner are very nice and easy to work with. The owner is quite charming in fact. read more

These guys are true professionals. You can tell when people don't do a job correctly and own up to it and fix an issue without question or denial. I had them install a sump pump basin and it worked okay but it was later was still spreading out in my crawlspace. So I gave em a call and they checked it out and immediately they told me they need to make it deeper and they'll have a crew out that weekend to adjust the work. It's rare to find someone who stands by their work, really lucked out with them! read more

Ernesto came to our house yesterday and investigated our damp basement. He was smart, courteous, and had a range of options for getting our basement dry, with some different ways we could manage it. He recommended products for mold control, baseboarding, and alternative solutions for the vents-- he showed us problems we didn't know were problems and showed us that some of the things that we **thought** were problems were no big deal. He gave us advice with the ultimate recommendation that we may not need his services for a year or two. It takes a rare businessman who will give that kind of advice. Thank you Ernesto! Looking forward to working with you soon (or if we follow your advice, maybe in a year or two)! read more

A truly professional company. They made the process of encapsulating our crawl space so easy and pleasant. The work crew was on time and professional. They protected our floors and hallway with plastic sheets. They answered all our questions and Ernesto himself came to inspect the final work that his crew did. We are extremely happy that we went with Ernesto and his team and we highly recommend their company. read more
