D&S Floor covering services the northern virginia area since 1999! We are a local small business willing to serve! We also offer financing! Come stop in anytime, shop at home or visit our website at www.dsfloorcovering.com
"Bought a home that needed top to bottom renovations, including almost 2000 sq ft of new hardwood, another 2000 of old hardwood floors/steps/banisters refinished, another 2000 of luxury vinyl installed, and carpet steps ripped out and replaced with hardwood. Of ALL our MANY contractors (tile, electric, painting, handymen, etc), Masood was the one person who's team showed when he said he would 100% of the time, did a great job the FIRST time (one crew ripped up old carpet and installed all the hardwood in ONE day, and another crew installed the vinyl in ONE day as well - honestly, I didn't think that much could be done in so short a time). He provided great pricing and wonderful service, advising me which flooring would be more durable and ordering in a flooring I liked best rather than pushing me into something easier to get. Masood is very easy to work with and made sure everything was done well. We had used him at a previous house and been happy there as well, but the new flooring in this house made a huge difference. Highly recommend D&S!"

Batt insulation excels in vertical installations because it remains firmly in place and delivers consistent thermal performance. Blown-in insulation performs exceptionally in spaces such as attics, efficiently filling gaps in irregular areas.
Employing both insulation types according to their strengths enhances your home’s overall energy efficiency and comfort by providing a tailored solution for every space.
Start by measuring the square footage of the space, then match that area with the insulation thickness you need to hit your target R-value. Add a buffer for waste and odd-shaped spots so every cavity is covered.
Once you have a rough count, run it past a local insulation pro—their on-site advice will fine-tune the numbers and help you avoid costly miscalculations.
Old insulation that is dry, intact, and mold-free does not require removal before adding new insulation; stacking new insulation over it maintains effective thermal performance and boosts energy efficiency.
If the insulation is damp, moldy, or deteriorated, removal is necessary to eliminate health risks and ensure maximum effectiveness of the new layer. A professional insulation contractor will assess your situation and recommend the most effective solution.
Installing insulation in an average-sized home using batts or boards requires five to 12 hours. Using spray foam or blown-in insulation requires two to five hours. These timeframes are determined by the area’s size, accessibility, and whether old insulation must be removed.
Complex projects and hard-to-reach spaces demand extra time. Hiring an experienced insulation professional ensures that the installation is completed efficiently and correctly.
Insulation is measured by R-value, which defines how effectively it resists heat flow. A higher R-value provides superior thermal resistance, ensuring your home remains warm in winter and cool in summer.
Choosing the correct R-value is essential for maximizing energy efficiency and comfort, and it directly impacts long-term utility savings. Professional guidance determines the optimal R-value for your specific climate.
