We recently had Michael inspect a home we’re considering in Shadyside, and I cannot recommend him highly enough. From the moment he arrived, it was clear how knowledgeable and experienced he is. He was incredibly thorough, taking the time to walk us through every detail, especially around the foundation, and explaining exactly what would need to be addressed and why.
What stood out most was his honesty. He didn’t sugarcoat anything or rush through the findings. He gave us a clear, straightforward picture of the home’s condition so we could make an informed decision.
If you’re buying a home in Pittsburgh, do yourself a favor and hire Michael. Knowledgeable, thorough, and honest. Five stars all the way.

My wife and I have been worried that the hairline step cracks in the foundation are going to be a big problem. Michael came out and explained what was likely happening and that he doesn't believe anything needs to be done at this time. I was still a little concerned that it may progress and we wouldn’t know, he offered a monitoring system that can help me reset easy. Thank you so much, Michael!

We recently received services from Keystone Basement Systems. We had a perimeter water guard system, a triple safe sump pump, as well as a clean space vapor barrier installed. I was little caught off guard at first, as the original rep that sold the system is no longer with the company. But Devon came out and put any questions we had to rest.
Honestly, it’s an expensive job and there’s a lot of anxiety that factors in to a wet basement. But I couldn’t be happier with the work that we received from their team. They had a three-man crew for three days, with Gavin being the lead. I have to say, the most comfortable part of the whole process was talking with Gavin, asking him questions, and seeing his work. Julien and Cooper were also champions in protecting our space with plastic, removing concrete, removing parts of our old system and all the additional hard work that is involved in this process.
It’s been about a week since the team was onsite, and we haven’t had an issue with water since they left. I’m very happy with the choices we made for this system. And very satisfied with the entire team at Keystone.

Great service requires great people, which needs to be recognized. Chis Bailey and the team at Keystone Basement Systems are phenomenal! Chris was prompt, polite, knowledgeable, and professional. He was extremely thorough in explaining the different options for our project, and provided variable pricing for those options.
He followed up with our local Borough for the required permit, and kept me informed every step of the way leading up to our installation date. Additionally, he touched base with the installation crew on the day of to ensure things were going smoothly. Much appreciated! I cannot say enough great things about Chris Bailey as a person of service, as he genuinely cares about people, and left a lasting impression on me!
Our installation crew of Rich, Dee, and Gavin were outstanding! All three of them are hardworking, and fun to be around. A supervisor stopped by during our drain installation for quality assurance, and I assured him the crew was doing a great job. Thank you to the entire team at KBS for resolving our water issue.

I wanna give a HUGE shoutout to the crew Rich, CJ, and Luke! GIVE THESE GUYS A RAISE! They work super hard, fast, and are professional! Very clear communication and showed up on time. Also incredibly friendly, informative, and were more than happy to answer any questions I had during the installation of the Waterguard, triple safe sump pump, and dehumidifier. It was a big project and I was thoroughly impressed that they knocked it out in just two days. On top of that, they left my basement cleaner than it was before. These guys really know their stuff and I can’t say enough good things about them. Keystone Basements is lucky to have these guys!
I also want to give a shoutout to the initial inspector Cam! I really appreciated that he didn’t come by to give me a sales pitch and pressure me into anything. He was just straight up about it. Basically said “hey, this is what your problem is, this is what we’d do to fix it. It’s your call.” He’s very knowledgeable and sat me down to go over the exact work to be done. I went the financing route, and he made everything simple and easy. Also gave me his phone number and responded almost immediately whenever I’d have questions leading up to the install.
If you’re curious about having your basement waterproofed, it literally cost you nothing to have them come by and check it out and give you a quote. This has given me much peace of mind, and am really happy with the work!
