"We had a blockage somewhere in our plumbing line and couldn't use our upstairs toilet for over a year. Our contractor Ben Sviri from Creative Home Remodeling Group came out to our condo with his plumber to assess it. Not only did they find the blockage (PVC pipe), they also removed it and patched it up the same day! We definitely recommend them with any home project you may have."

"It went great! I would highly recommend KN Remodeling. We had a master bathroom remodeling done. Turned an outdated bathroom, into a tranquil, and relaxing place to bathe. Nathanel was very professional and handled this project with an open mind to meet our expectations. The project was also managed in a timely manner, it was truly wonderful to see my vision come to life!"
