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."

At Window Nation, we know replacement windows. We’re third-generation window replacement experts who have been lucky to provide homeowners replacement windows, siding, and doors for over fifteen years. We opened our first showroom in Maryland in 2006, quickly growing to serve homeowners in cities across the country – and we’re not stopping there. We’re grateful for every homeowner who has trusted us to upgrade their most important asset: their home. We’ve learned a lot about home improvement over the years, but the most important thing we learned isn’t about window replacement. We learned the home improvement industry isn’t about offering the best windows, siding and doors; it’s about the relationships we build with our customers.

"Professional, timely and best installers we’ve had. Our installers took to time to get everything fit right. They had their hands full with a few doors and windows, due to bad framing from our construction contractor. Our new doors and windows work flawlessly now."

Insulation questions, answered by experts

The most insulative type of insulation for behind drywall is spray foam insulation, but this is the most expensive insulation available. The most common insulation—sometimes considered the best for the value you get for the money—is fiberglass roll or fiberglass batt insulation, which is significantly more affordable but also far less insulative. The best kind of insulation for your house will also vary based on the climate in your area, your budget, and more. A professional insulation company can help you decide which type is best for your home.

Canned spray foam has an R-value of R-3.7 per inch. However, it’s not great for use as insulation. Also known as single-component spray foam, it doesn’t expand as much as two-part types that work for insulating the whole house. Save the canned foam for gaps around doors and windows.

DIY installation is feasible with the right protective gear and knowledge, but professional installation ensures full coverage and maximum efficiency.

The life span of fiberglass insulation can be as long as 80 to 100 years, but because of changing building codes, it’s best to get your insulation checked every 10 to 15 years. Signs of degrading fiberglass insulation include bits of batts on the floor or batts detached from frames. Having optimal, healthy insulation in your home will improve its energy efficiency, lowering your monthly bills.

Depending on where you live and the conditions of your basement, you may not need to insulate your basement. Your best bet is to talk to a basement remodeling company to find out what they recommend doing.

Insulating your basement can help improve your home's energy efficiency, but it will also increase the cost of your basement remodel project. The average cost of installing basement insulation is $2,400.
