Family owned & operated, majority of work is by customer referrals. Two employees, no criminal records or use of sub contractors. Owner is on the job site. Cost determined by the job. We do not have a showroom because we prefer to pass on the savings to our customers by keeping our overhead low. Quality Wood Flooring offers installation of wood flooring and also refinishing of existing floors. We can also provide and install Luxury Vinyl Products. We can provide the raw material with job site install and/or finishing. We also can provide pre-finished flooring, or you can provide the material and we install it. We prefer not to show color samples when bidding the job site finished flooring, instead we show the stain colors on your floor after sanding, in your lighting, to get the true custom color you desire. We are a member in good standing of the Better Business Bureau. We service the entire St. Louis and Metro east area. Free estimates over the phone, or in person, if you are within 50 miles. We are insured and most of our business is from word of mouth. We book up quickly, so please try to contact us as soon as possible to get on our schedule. We try to accommodate our customers as much as possible, and will work some weekends to fit people in, but unfortunately, we cannot guarantee to be available for you, unless you give us adequate notice. We can be booked up at least a month in advance, but schedules change, and can be adjusted, so do not be afraid to call, and we will try and accommodate you.

FAQs for insulation install or upgrade projects in Saint Louis, MO

Yes, insulating an unfinished basement delivers meaningful benefits even if you don't plan to finish the space. Proper insulation reduces heat transfer through basement walls, which can account for up to 30% of a home's total energy loss. 

This improvement enhances comfort throughout your home while potentially reducing energy costs. Insulation also helps manage moisture levels, protecting your home's structure and improving indoor air quality.

Rigid foam board and spray foam insulation provide superior moisture resistance for basement applications. These materials create effective vapor barriers while delivering high R-values per inch of thickness. Rigid foam boards resist water absorption and can withstand occasional dampness, while spray foam creates an airtight seal that blocks humidity infiltration. 

For basements in humid climates or with moisture concerns, these options outperform fiberglass or wool alternatives.

Insulating basement walls provides the greatest benefit by reducing heat transfer through your foundation. This approach helps maintain consistent temperatures throughout your home and keeps floors above the basement warmer during cold weather. 

Ceiling insulation might be appropriate if you specifically want to isolate the basement from living spaces above. In most cases, addressing the rim joists and exterior walls delivers the best performance for energy efficiency and moisture management.

Many building codes require vapor barriers when insulating below-grade spaces like basements. These barriers help control moisture migration through foundation walls and floors. Certain insulation types, including rigid foam and spray foam, provide inherent vapor barrier properties. When using fiberglass or wool insulation, a separate vapor barrier becomes necessary. Always check local building codes for specific requirements in your area.

Signs that basement insulation needs replacement include persistent cold spots, unexplained increases in energy bills, visible moisture damage, musty odors, or mold growth. Physical deterioration, such as compression, sagging, or discoloration, also indicates potential problems. 

In older homes with outdated insulation materials, upgrading to modern options with higher R-values can significantly improve performance. When in doubt, professional inspection can help determine whether repair or replacement represents the best approach.
