Customers frequently cite punctual scheduling, clear communication, and reasonable pricing as key benefits of A-Proseal’s services, which include foundation crack repair, crawlspace encapsulation, and drain tile installation. Reviewers note that the team explains processes in detail and completes work efficiently, often within days of the initial inspection. However, isolated low-star reviews indicate that some clients experienced a lack of communication regarding quotes, feeling that their time was wasted without receiving a response or job acceptance.

I have called on A-Proseal for various projects at my house at different times, because they do honest work at a reasonable price, and they are responsive, professional, and skilled/careful/neat in their work. They were recommended by some people in my neighborhood, and based on my experience with them, I highly recommend them as well.
We had a great experience working with Fernando and his team. They installed a waterproofing membrane for us at a very reasonable price, and the work was done professionally and carefully.
More recently, we experienced a separate water intrusion issue that was unrelated to the waterproofing work they had previously completed. Even though it wasn’t caused by their work, Fernando was incredibly kind and spent over an hour with us doing water tests and trying to trace the source of the leak.
We truly appreciate his professionalism, kindness, and dedication, and would highly recommend him to anyone looking for waterproofing work!

A-Proseal saved the day on my basement project. I needed 24 cracks filled on the walls of my basement before we could frame and insulate the walls. The contractors were ready to start and A-Proseal got their whole team of guys to come on a Saturday on short notice! They did an amazing job and I can't express enough gratitude. Their prices were lower than many of their competitors and they use actual epoxy to fill the cracks and bond the concrete rather than poly foam which just an inferior solution.
Response from the owner · 4 months ago
Dear Eddie
Thank you so much for the kind words regarding your basement project. I am glad our team could make it out on short notice this past Saturday
We take pride in using high-quality epoxy to ensure a permanent bond for the concrete, and I am happy to hear you are satisfied with both the results and the pricing. We appreciate your business and the positive feedback.

A-Proseal did a fantastic job repairing the cracks in our basement. Recently, they completely repaired one of our basement window wells. With all of the recent rains we have had, there were no leaks or water in our basement. They are highly professional, explained the process in detail, and thoroughly answered our questions. I would highly recommend A-Proseal! The company's name should be A+Proseal because they do A+ work!

Frank ConstantLocal Guide · 44 reviewsiTotal number of Google reviews Frank has written across all businesses on Google Maps, not just this one.
We had a few cracks in our foundation, one of which was major and required carbon fiber straps. In 36 years here, we never had any water issues, just cracks. A-Proseal was highly recommended by the owner of a different waterproofing company who was retiring.
The scheduled inspection process was smooth and informative. The quote was very fair. The team was on time for the scheduled work. They were conscious of cleanliness and dust, and made sure we were totally satisfied before wrapping up their work. The transferable lifetime guarantee is important. We are 100% satisfied with the process, the cost, and the finished product.
