      G & J waterproofing did an excellent job installing a new drain system and pump in my basement. Their employees were exceptionally polite and neat. After the job they cleaned up and made sure everything was in order. Would definitely recommend using them.

      We got a number of bids but everyone else wanted to do a lot of things that we felt weren't needed and that over doubled the price. This was a one-day job, and everything was done that we contracted for. They didn't try to up sell us.

      G&J waterproofing did a great job in my garage to secure a caving in wall. They were efficient and did a great clean up and they were very nice. I would recommend them to anyone.

      We had waterproffing and interior French drain installed in our basement and garage in May, 2022. The work was done very well and completed in appeoximately one week, the estimated time given. The basement and garage were then treated for mold by *********, a partner of C&J. We are very pleased with the system which functions as promised during heavy rain events keeping basement and garage dry.

      I have a home in the Northside that is over 100 years old and it had water damage in the basement and all the floor joists needed to be replaced, so I knew I had a big problem on my hands. I was recommended G&J from the structural engineer(who is one of the best engineers in the city), so I felt confident. After speaking with *****, he was quick to give an estimate and tell me exactly what needed to be done. The project was done close to the timeline given(big projects like this always fluctuate a day or two). ***** was very communicative with me throughout the whole process, especially since I do not live in ********** anymore. All of the work that said would be done was completed and(waterproofing the basement, all new floor joists, new floor installed). ***** and team do great work and I can feel comfortable now that our foundation is solid. Highly recommend!

      I have a Hundred plus year home in Carnegie. The previous owner heavily painted the basement to hide the water damage over the years. As we had a lot of heavy rain this summer the paint start fading and the basement started to show water. I had numerous contractors come to the house telling me the problem and how to fix it. G&J gave the most comprehensive analysis and explanation to the problems and solutions. They did not try to tell me extra equipment that wasn't needed. When I suggested some extra work they told me they would be happy to do the work but it really wasn't necessary.They completed the job. It took more time due to complications but they did not charge any extra. I would recommend them. There business is very busy so you just have tp work around there schedule.
