"I had my basement waterproofed with Innovative Basement Authority. Bryce J. was my inspector and was very knowledgeable and helpful. He gave me some great advice about my home. Adam S. and Josh W. completed the project and did a phenomenal job. They were courteous, professional, highly skilled, and did a great clean up as well. I was so impressed with the results, I would definitely recommend their services."

"We contacted them for an estimate on our basement. Initial phone call and connection went well, very professional, quick, and prompt. Once the rep was at our home he went into a "pitch" vs. listening to what we said we already knew we wanted. We even had a sketch. Eventually we went to review the space, take measurements, etc. We then started to pick out materials......he brought all the samples but then put together an evaluation based on square foot and overall price of our home and used that based on the square footage of our basement to determine a "fair" value........which was $100/sq ft. That would have equated to over $100,000 basement. Then he said how much "fairer" their price was at the quoted rate. We were too far apart in our estimates which is fine with me, but at the end he said if I obtained a quote that was lower ~ to give him a call and they'd see what they can do. At that point, I believe "no thanks". Give me your best price up front. The entire visit took almost 3 hours. It was a big waste of time for all unfortunately as we had no intent to spend that much.
