We highly recommend Basement Expert. Being new to the area we talked with a lot of companies about waterproofing and other house projects and we were initially impressed with Basement expert’s clear communication and they didn’t seem like they were trying to sell us something we didn’t need.
After hiring them, the clear communication continued and we found them to have integrity and take pride in their work. They were also very clear and fair about pricing and definitely earned our trust. We can now rest easy when there is heavy rain knowing that their work is protecting our home and the money we have put into our other improvements!
Vlad of Basement Expert Waterproofing recently diagnosed my basement leak issue. He came with scopes and moisture readers, and was able to not only verify the condition of work I had done previously with another company, but suggest what a reasonable fix would be. He came out the day after I called, and while we had planned to do the job the following week, he was able to complete the job the same day when space opened up in his schedule. I can’t believe it. In the midst of rainy season I got a same day fix with a new rock well and diversion system. These guys are honest, professional, timely, and cost effective. Total pleasure working with them, and they will for sure be the first ones I call if ever I need this type of service again. Thanks Vlad and crew.
We called Basement Expert to come out and take a look at an overflowing gutter drain pipe that was causing water to pool near our foundation during heavy rain. They were very responsive and professional and Vlad and his team were able to come out the next day. When they arrived, they scoped our underground drain pipe and found no issue, but they did note that the gutter itself was not installed correctly and that the adapter from downspout to drain pipe needed replacing. They went to grab supplies and came back right away to fix it. They also didn’t charge us for the work because it was a small fix! I was super impressed with their work ethic, attention to detail, and willingness to help us for free. I would recommend anyone to give them a call if you think they could help you out! Positive Responsiveness, Punctuality, Professionalism
Basement Expert did a great job installing a french drain in my basement rec room, no sump pump necessary. Large room, required 1 short end and 1 long wall foundation footing repair, backyard drainage trench. Waterproofed the wall and replaced the original wainscoting so all that was needed was some paint touch up. Cleaned and disposed of debris, finished in 4 days. Explained the process and estimate was accurate. Recommended.
They are knowledgeable, showed up consistently, and provided updates when unexpected obstacles came along. We have a tricky foundation at the base of a wet hill with poor access and they built complete foundation and runoff drain systems in less than 2 weeks.
These guys just finished our project and we are so happy with a final result! Competitive price, great quality, perfect communication and clean work! Highly recommend!!!
