"I’m a 70 year old Senior. I had sagging at the end of my hall, in my 3-BR ranch home. I got five other quotes, none of which suggests a problem with my foyer or kitchen. They sent out some 20 something young man -that clearly did not know what he was doing to complete my main beam replacement project. I mentioned to David (the 20 something) and his assistant IMMEDIATELY, that my kitchen cabinets had pulled away from the wall and the foyer was tilting. Several times. He assured me that he would run the beam right up under the kitchen between the kitchen and the foyer, to the garage door —to correct it! I had an intense disagreement with him when he tried to leave and did not make any attempt to correct the damage. The damage they had caused. I used my burial money to correct this sagging in the hall-and they left me with a huge problem with my foyer and kitchen that WASN’T THERE BEFORE, that they caused, & knew they caused. Indiana foundation, now Groundworks, sent Blake to my house under the guise of completing my first adjustment to the main beam, and as I had instructed them, to formulate their repair project based on a certified Home Inspection Specialist that I had hired to let me know what, specifically, Ind Found. should do to correct the serious problem they created. They promised to schedule the repair work at that time, but have ghosted to me ever since coming to see the damage they caused and formulate the repair. I have not been able to get in contact with them since; I’ve left numerous v-mails and texts. They have no integrity towards my project and nor will they have ANY integrity towards yours."

We are a family owned and operated company that takes great pride in a job well done. We have been fixing foundations for three generations.

"This company repaired all wall cracks in my basement and installed a drain system on all walls of my basement. This company showed up when they were suppose to and completed the work on my basement in a timely matter. I had to contact this company to come back out after the work was done but come to find out, the problem we experienced was not due to any of the work this company had previously done however they still repaired the problem without charging us anymore money. Would definitely recommend this company to others."

"I know this is a book, but please read before contacting them. I don't consider this project completed but it was the only way that I could write a review. We still have 1 major issue that I can't get them to fix. I was stupid & paid because they said they would be out to fix the encapsulation. Double stupid because I trusted them. 3 months - still not fixed and now we have water in the crawlspace. Phase 1 took 11 days instead of 3 - a lot of crawlspace work (broken water pipe that they did not break.) Phase 2 was and still is a disaster. Scheduled for 13 - took 34 days. New subflooring (2 - 4 ft) was needed on all outside walls, a main beam, jacks.. We still have unlevel floors, we have uneven matching between new and old subfloor (+ other issues). The project manager did fix some of the issues. It took 7 weeks (renters living in the garage, rent free because that was fair), to complete and fix some of the issues. But the wall encapsulation is still laying on the ground - in water."

"I am very disappointed with The Foundation Specialist. Their price quote was more than double that of a competitor, which raised concerns from the start. I canceled the contract within the 72-hour period as allowed under the Federal cooling-off rule, yet more than 10 days later they have failed to refund my $5,500 deposit. I have called multiple times and was repeatedly told that the sales manager would contact me, but no one has followed up. This lack of professionalism and failure to honor a lawful cancellation is unacceptable. Based on my experience, I cannot recommend this company to anyone."

Basement Waterproofing questions, answered by experts

While it’s possible to seal a foundation yourself, it’s not recommended, as it’s a tricky and labor-intensive job. Foundation sealing is best left to the pros to save yourself time, remove the risk of doing it wrong, and keeping yourself safe. Call a foundation repair professional near you to see what the job will cost.

If a crawl space isn’t vented, there can be moisture buildup, which can lead to mold damage, easily destroying the foundation of your home. A closed-off crawl space can trap heat, which can be useful in the winter, but can also trap dangerous gases and prevent clean air from entering the home through the floorboards.

Installing storm windows can protect your home’s interior from heavy storms. Most storm windows are made with enamel-coated aluminum with screens and sliding glass panels. They also make your house more energy-efficient. The average storm window cost is $12,000, ranging between $4,250 and $19,850, depending on mounting, window types, glass types, and frame materials.

The best way to waterproof a basement is to install a properly functioning gutter system and a French drain around the outside of the foundation. The best solution for your home could involve other waterproofing methods that resolve the problem unique to your situation. Depending on your soil type, climate, and other factors, that could include sealing, landscape alteration, interior drainage systems, and more.

The process might take a few days to a week, depending on the method chosen, area size, and weather conditions. Some solutions, like simple interior sealants, may require less time.
