customer: “it’s probably not that bad behind the wall”

me 3 minutes later: “THAT was behind my wall?” 😳🐾

“G&J was referred to me and the overall experience was professional. There were no high pressure sales and I felt very comfortable using them. Their price was fair and I will be referring them to those in need of waterproofing for their basement.”
— Candance

Another 5⭐️ review from a happy homeowner. We believe basement waterproofing should be straightforward, honest, and pressure-free from start to finish. Thank you, Candance, for trusting G&J Waterproofing and for recommending us to others — it truly means a lot to our team. ❤️🖤

Before ➡️ After on this full exterior transformation.

We repoured the damaged concrete steps, rebuilt the failing retaining wall, and poured fresh concrete below to create a strong, stable foundation from top to bottom. Water and shifting soil had caused major deterioration, but rebuilding everything the right way restored both safety and long-term stability.

Solid support, proper drainage, and clean concrete work — all done by G&J Waterproofing.

Starting a brand-new retaining wall project. 🚧

A failing retaining wall can lead to shifting soil, poor drainage, water intrusion, and added pressure against nearby foundations. That’s why proper prep and installation matter from the very beginning.
We’re getting this site ready the right way so the new wall is built for strength, stability, and long-term protection.

“G&J helped us with a really poorly timed water leak in our basement just before we listed our house for sale. I met with the owner on a Monday, and the following week, the whole crew showed up to get the interior French drains and sump pump installed quickly and professionally so we could maintain our listing timeline. The crew worked efficiently and were very friendly! The final step of returning concrete to the floors looks amazing! Communication was great from start to finish, and you can tell they all take pride in their work and customer service. Out of estimates we obtained, G&J was reasonably priced for such quick turnaround of getting the job done. Now we can confidently list and pass the warranty over to the new owners. Thank you G&J!”
— Renee

Another 5⭐️ review from a happy homeowner. We know how stressful basement water issues can be — especially during the home selling process — so our team worked quickly to install a full interior French drain system and sump pump while keeping everything on schedule. Thank you, Renee, for trusting G&J Waterproofing and for the kind words about our crew, communication, and workmanship. ❤️🖤

Before ➡️ After on this garage transformation.

The old floor was failing, uneven, and showing signs of movement. We removed the damaged concrete, installed new wall straps for added structural support, and poured a brand-new floor built to last.

Strong foundation. Solid floor. Proper support. That’s how G&J gets it done.
