Basement Waterproofing Portfolio

In June 2022, Capstone Waterproofing performed an awesome job waterproofing my basement. Joe exemplified optimal professionalism.

He was very patient with explaining the work to be performed and responding to all my questions. The team that was selected to provide my service, arrived on time and completed the job timely as promised.

They left my basement as cleaned as before their arrival. I am very satisfied with the outcome of the job performed and I would highly recommend Capstone Waterproofing.

This has to be the best experience by far of all the contractors we have worked with! I can’t say enough about the great people who worked on our property! Joe kept us informed through the entire process.

His knowledge eliminated our stress right from the beginning! The finished product was superb! His crew went above and beyond our expectations!

An A+ rating is still not good enough ! Capstone Is amazing in every way!

I am grateful for the talent and expertise of Capstone Waterproofing. The owner genuinely loves what he does, is patient with questions, and willingly provides education so customers are able to make wise choices.

From estimate to completion, Capstone Waterproofing was timely and responsive. The estimate was scheduled quickly, the quote provided promptly, and each day of work began timely. The quote had enough detail to be confident in my decision to trust their approach to protecting my home.

I especially liked that the Project Manager was Onsite and available to address deviations to schedule and ensure optimal performance.

For example, they anticipated rain near the end of the project and changed the schedule to accommodate. In addition, I received videos/photos of each stage of repair. Seeing the water leaving my property, now replaces the anxiety/memory of sump pump failure and flood.

Contacted this company as I found mold growing in my basement. I lived in the home for years and wonder why I continued to have headaches all the time. Didn’t know what the cause was.

Once Capstone came into my home and ran tests they found my issue. Quickly set up a plan to clear out the mold and stop it from coming back. The work was excellent and completed in a timely fashion. I will definitely be using Capstone in the future.

Capstone was wonderful to work with: they were quick, professional, clean, and responsive.

The work was high-quality. They were transparent about the whole process, and the cost was reasonable compared to other estimates.

I loved how honest they were and how they explained everything they were doing as they were doing it. It’s so important to know what’s going on with your house.

I am forever grateful for the work they did to waterproof our basement and fortify our foundation.




If you want a company that shows compassion and is passionate about their work then Capstone Waterproofing Solutions is the company to seek.

I experienced water damage in my basement and only learned through Joe and Clyde’s seek and discovery consultation that the water damage was due to a crack in the foundation in the basement wall.

Joe went over the whole process verbally and in writing as well as provided educational material to further explain what happened in my situation and the process of resolving the issue. I was in total awe because I had three other waterproofing companies to provide a consultation and quote and NONE of the other companies did a seek and discovery let alone provided material to further educate me on the problem I was experiencing.

Joe kept me informed on everything. Joe and his team is very professional, always on-time, reliable, and informing. They did a fantastic job in correcting the issue. The team was very professional in the work they performed in the inside and outside of the home looks great.

I highly recommend Capstone Waterproofing Solutions to anyone that need their services.


Ria Jackson


We discovered water in the basement thinking the origin was a crack in the foundation, so we contacted Capstone. Everyone was extremely professional from the first phone call through the consult and assessment.

Joe called prior to arriving and arrived right on time. After a thorough assessment, he patiently explained what he discovered and answered my many questions.

The issue was not a waterproofing issue, but he did make some recommendations on how to proceed with our issue. He also shared some maintenance tips and other useful information.

Joe was extremely professional and provided excellent customer service.
