Client Testimonials
Luis came out and was here for a couple of hours, really trying to find the source of the issue. He actually found three spots in the area where water was coming in! The leak report was very detailed and included pictures, so I understood everything they found and where. The estimates for completing the work were clear. While a bit on the pricey side, the peace of mind that came with everything was worth it imo, and they were able to take care of each issue without me having to spend time finding different professionals, getting multiple quotes, and be available at different times. They did offer a discount off their hourly rate if we had them also repair the damaged interior areas, and they credited back the money spent on the leak test. The interior ceiling and wall look good as new.
It has been 3 months since the repair and the area is still dry - and we have had many downpours since then, so it has been throughly tested! Josh has also texted me to check in every few weeks to make sure everything was still good.
I recommended Dr Leaks to a coworker of mine and so far she has been thrilled with the detailed service as well. I highly recommend Dr Leaks if you want your leak to be dealt with for (hopefully) the final time!
Don’t waste your precious time or hard earned money anywhere else. If you have any signs of water, immediately call Dr. Leaks!!
DEFINITELY entrust Dr. Leaks with your issues! Thank You🙏🏾
Haven't had rain yet, but all went well with leak-report and initial work.
Steven M. and Danny were wonderful--professional, quick, and expert, and the place is clean and tidy, inside and out.
I was also impressed with communication and follow-up by Josh and Hanlon, from Dr. Leak's office.
A+++ recommended if you don't know a leak's source, or if you need everything taken care of by one contractor.
areas. They offered an estimate to also repair, but we ended up going with a different contractor crew for the repairs simply due to cost.
Would highly recommend for anyone trying to find the source of a leak into your home!
Instead i hired Dr. Leaks and they found the leak source within a few hours. It was from a deck directly above the leak. The crew who came (thank you Louis!) were great- on time, worked quickly and efficiently, and I now can finally get this ongoing problem fixed. This was well worth the money and time spent. I very much recommend this service. Had I known about them before I could’ve avoided years of headache and repairs that failed over and over again. Five stars…very impressed.
