There were ripples in my 20 year old carpet. I called Roy Lomas Carpets and they sent out a technician to stretch the carpet. He did an amazing job. He pulled up the carpet at the wall and pulled it across the room. I was in shock at how the carpet moved and the ripples went flat. The technician explained that depending how long the carpet was rippled, even though the carpet was flat it may be creased. He explained that with vacuming and light cleaning the creases should come out. He removed all large pieces of pad and carpet then asked it I had a vacumm to get the small pieces. I told him I would take care of the clean up. After we vacummed and put the furniture back, the carpet looked like it had just been laid. I would call Roy Lomas Carpets for any service I need on my carpet in the future. The service was done in a professional manner, they worked around my schedule, showed up when they said they would and the price was reasonable.
