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.

"We ordered over $20,000 in windows, doors, and interior trim from wilke. Things went well until the person that we ordered everything from abruptly was no longer there. We were assigned another salesperson who seemed disinterested in seeing the project through. All three of the sliding doors wilke sent out had issues. I first informed wilke of the issues 08/07/17. They came out a few months later and fixed two of the three doors. I called them and told them that they forgot to fix the sliding door in our master bedroom and that the door in our living room had broken again. They sent someone out a second time (a few months later) but it was with the wrong parts. It is now 02/23/18 and they still have not fixed the two doors that have been broken for over 6 months. They blame the delay on not being able to get the parts but in reality, they did not even order the correct parts until we escalated the issue to upper management. We are now waiting for the parts to come in and wilke to hopefully fix the sliding doors. But they are estimating that to be in March. I went with wilke because of their claim of customer service. I will never go back again and I hope anyone reading this does their homework."

FAQs for attic insulation installation projects in Fenton, MO

The best attic insulation depends on where you live, the project stage, and your budget. New builds often benefit from structural insulated panels for top-tier efficiency, while homes in very warm regions can see big cooling savings with reflective insulation. Blown-in, loose-fill, and spray foam all excel at filling odd spaces in finished attics. Talk with a certified local pro to match the material to your climate, space, and wallet.

You’ll only need a licensed electrician if the project calls for moving existing wiring or adding new fixtures. For straightforward insulation jobs, your insulation installer can work around current cables. That said, never start insulating until a pro has checked any questionable wiring. If you suspect damaged or outdated circuits, book an electrician first to keep the project—and your home—safe and code-compliant.

Without air sealing, even the best insulation can underperform. Gaps let heated or cooled air leak out, forcing your HVAC system to work harder and driving up energy bills. Sealing those cracks before adding insulation locks in conditioned air, keeps moisture at bay, and helps the new material hit its full R-value. Ask your insulation pro to tackle sealing first so you enjoy consistent comfort and lower monthly costs.

Among readily available options, structural insulated panels and rigid foam boards top the charts with R-values that can reach 8.0. They’re ideal for new construction or very cold climates where maximum thermal resistance matters most. If you live in a milder zone, blown-in or loose-fill insulation may deliver plenty of performance at a lower price. Weigh the upfront cost against energy savings—and lean on a local pro’s guidance—to pick the smartest fit.
