My husband and I bought carpet and laminate flooring from DeGol brothers in 2004 and had a very good experience with them.
The selection of carpet and flooring at their Wye Switches location is fantastic. In fact, you might even say that there are too many choices, since it took us about two weeks to decide on the carpet!
The salespeople were very helpful, and let us take home many samples.
We also had them install the carpet (we did the laminate flooring ourselves) and were very happy with the work...they arrived on time, and did a nice job.
So if you are looking for a great selection and good installation, check out DeGol's.
