"Called company on Monday and got an appointment for an inspection on Wednesday. That following Monday, the technician arrived and went through each step is sealing off the concrete foundation to the water leak. The fix worked well and was put to the test with the recent record rains. Not one drop of water came into the basement."

"I must say Victor and his team of professionals from Perma Seal did an emaculent job, explained every little detail to my understanding and l didn't have to keep asking questions..l would definitely recommend him and his team to anyone who needs their home waterproofed, and l will request him and his team if l ever need similar work again..5 STARS TO VICTOR AND HIS TEAM*****"

"Devin Rhoades was excellent at explaining in detail about our needs and possibilities in fixing our support wall and encapsulating our crawl space and draining the water away from our house. He was well informed on all aspects of our situation. I would recommend Devin and Chicago Basement Systems to anyone needing help with basements or crawlspace issues."

"Jason and team did a great job.  Jason came out within a day or two from my initial email and we discussed all the options/services they provided (liner, concrete, crack repair, and spray foam insulation.  I really appreciated how he discussed the pros and cons of each solution and his low pressure style.
ABC Crawlspaces prices were the the lowest of all the bids I got and I was even told by other insulation companies if I could get closed cell insulation for that cost that I should go for it.  The best thing was their service and quality of work.  It is rare to find a company that has fair prices and good service, but ABC Crawlspaces is one of those companies.  We are very happy with all they did for us and our basement is much more usable and the air quality has improved dramatically.  Thank you Jason!"

"We have a 1920s bungalow with a cinderblock foundation and routine seepage issues.  Interior drain tile was also an option but with a partially finished basement, I think ultimately would have been more expensive after putting walls back together, etc..  And, personally i'd rather stop the water before it enters the house.  I felt as though i was getting the "cookie cutter" solution from the other highly rated angies list waterproofers and they definitely like to nickel and dime on their expensive battery backup systems.  Chuck spent a considerable more time at the house, didn't give us the BS sales presentation with all of the pamphlets, gave us a timely quote, and ultimately just made us feel the most comfortable.  
The job went very well and I wouldn't hesitate to use High Tech for additional jobs in the future.  Chuck is very professional and responsive, easy to work with.  It took a while to coordinate with the excavator which is subbed out, but we were in no big rush and everything worked out great.  The job took four days.  We've had some heavy fall rains and not a drop of water in the basement.

"We have had 2 good rains since the cracks were repaired and haven't had a drop of water in the basement. Everyone we dealt with was very professional and knowledgeable. Very pleased."

"Excellent! Job was done in 2 days! Basement is very very dry!"

"We had a different person who came out before them who was horrible and then I tried Crawlspace/Basement Waterproofing Solution because they were reasonably priced and they worked with me on scheduling their time so that they would be there when the electrician are there. They worked together with the electricians and were all done. They were wonderful. It was an all-day project but everybody worked together. Everybody showed up, everybody cooperated, and it was all done in one day with a big job. They were very good with the whole thing. The price was really good deal and all they have to do is seal from the outside to the inside. The biggest thing for us is that, they were here when everybody is here to do one thing. They are really good and we only had one problem but it was all filled up. This company gave exactly what we needed, showed up when they are supposed to, and did a great job. It was perfect. I would recommend right away to anybody before anybody else.  We were very impressed with them."

"We experienced water in our basement for the first time due to our sump pump failing. We went to Home Advisor and found AUS. They responded quickly late in the evening and a few hours later we had a new sump pump installed and water quickly began recede from our basement. Our tech was amazing and very professional. He left our home just before midnight and had more homes to do. We were very pleased with the quality and timeliness of the repair and would definitely recommend AUS again."
