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

Insulating an unheated garage can still be worth it. For instance, insulating an attached garage can help with heat loss from your house in general, and it can also make it easier to store electronics in your garage without worrying about them being exposed to extreme temperatures.

If you use your detached garage as a workspace, insulation can still make a difference. Plus, you can use space heaters and a window unit AC to help condition the space while you work without installing heating.

The most energy-efficient windows are double—or triple-pane windows with low-emissivity (Low-E) coatings and gas fills between the panes. These windows reduce heat transfer, prevent drafts, and help maintain a consistent indoor temperature. But if replacing windows isn’t in your budget, pairing your existing windows with insulating window treatments can still make a noticeable difference in home comfort and monthly bills. 

Polyisocyanurate foam, or polyiso for short, has the highest R-value per square inch: 6.5 to 6.8. Polyiso is a rigid foam that comes with a reflective foil on both sides to serve as a radiant barrier. Given its high R-value, rigid foam is usually meant for foundations and basement walls.

Insulation is professionally installed by measuring spaces, cutting materials to fit correctly, and placing them without gaps for optimal thermal resistance.

Whether or not you need to insulate exposed ductwork depends on state and local building codes. There is no national requirement for duct insulation. Even if your local codes don't require it, duct insulation can be useful to increase the efficiency of old, thin, or flexible duct materials. Ducts should also be insulated in basements and ceilings to avoid condensation.
