Foundation Recovery Systems, founded in 1992, is a subsidiary of Groundworks, a family of companies that offers superior, proven solutions for your foundation repair, structural repair, crawl space encapsulation, dehumidification, and concrete leveling needs. They currently maintain offices in Kansas City, Moberly, Springfield, and St Louis. Foundation Recovery Systems is a recognized accredited member of the Better Business Bureau and devotes its years of experience, industry knowledge and specialized training to help customers protect their homes or commercial buildings from water damage, concrete sinking, and foundation failure.

"As far as we can tell, the work was effective at stabilizing our foundation, and the on-site crew led by Luke was great, informing us of their progress along the way. However, we expressed in advance our concern about protecting some of our landscaping. We were assured the crew would have boards to cover landscaping on which removed dirt would be piled. This turned out not to be the case. I’ve had quite a bit of expense and labor to restore landscaping that was damaged during the work. This damage could have been avoided. Foundation Recovery sends out $500 coupons to advertise for their work. My attempts to contact Joe and FRS to honor even a part of the $500 coupon to help defray my landscaping costs have gone unanswered. Our salesperson, Joe, was not present during the work and has not been responsive to our followup inquiries. We are very disappointed in the poor customer service from Foundation and its representatives. I cannot recommend this company based on their failure to address our up-front concerns, lack of response to our followup requests, and the false advertising that is associated with the coupons."

Insulation questions, answered by experts

STC (Sound Transmission Class) ratings tell you how well something blocks airborne noise. It’s a single number that sums up how much sound a material, like a window, can stop across regular speech frequencies. The higher the number, the better the sound reduction. A typical single-pane window hovers around STC 25 (where you can hear normal conversations), while well-sealed, double-pane options can push past STC 45 (which blocks out loud speech and most music). Just keep in mind that STC doesn’t cover everything—low rumbles like bass or thunder can sneak through—so pairing methods are always ideal for the most peace and quiet.

A plastic vapor barrier should completely cover your basement to prevent water from penetrating through the walls. This typically goes before installing insulation to prevent moisture from building up and becoming trapped on the inside of your insulation, where it can collect and lead to mold damage. Installing insulation after the vapor barrier allows for any moisture to exit the walls for better ventilation.

Yes, doggie doors, like all entrances, can let both hot and cold air into your home. However, as with any door in your house, you can take steps to weather-strip your pet's entrance to prevent air leaks.

The most obvious con of injection foam is the cost. It’s much more expensive to install than fiberglass or spray foam, but it may be your only option (unless you want to remove entire walls around the home). Another con is that it involves drilling into existing material, which has to be repaired after the foam is injected. Some injection foams are made from products that aren’t environmentally friendly, and improper installation can lead to trapped moisture, which can lead to expensive mold remediation down the road. 

The primary downside of radiant barriers is their limited effectiveness in cold climates. They are designed to reflect radiant heat, making them less beneficial in cooler conditions where heat retention is more important. 

Radiant barriers require proper installation to maximize effectiveness. Incorrect placement can lead to minimal benefits. They also do not provide insulation, meaning they should be used in conjunction with traditional insulation for optimal energy efficiency.
