We had our bathroom remodeled by Ridgeline Remodeling Group and couldn’t be happier. We’re in Matawan and went with a full tub-to-shower conversion plus new tile and vanity. The crew was on time every day and kept the job site clean, which mattered a lot since we only have two bathrooms. The whole project took about 3 days, right in line with what we were quoted. Communication was easy throughout, no surprises on cost or timeline. Would recommend them to anyone in the area looking to redo a bathroom.

Response from Ridgeline
