Carousel Carpet in Bowie did our family room several years ago. Did a very good job. I had them back a couple years later to re-stretch the carpet - so they stand by their work.
We used lowes for our house and just after a year the carpet started to get rolls in it lowes said sorry 12 month warranty on labor...
Won't get carpet again from anyone who doesn't offer a good warranty on labor. Carpet has been great. Held up well but it just wasn't pulled tight enough durning the install.
Carpet One in crofton. We had them install a vinyl laminate floor a few years ago. A year and a half after install we had a small problem and they sent someone out the next day to repair it free of charge. Very nice people that stand by there work.
