"This isn’t the first time County remodeling has done work for us! I added above windows, siding and doors because they did that a few years ago for us, and were great to work with. We were happy to have them back to help remodel our basement and add a shower to our bathroom. They did great work! My bathroom is exactly as i had envisioned in my head. I absolutely love it!! The quality of workmanship and materials used is above and beyond my expectations. Respectful of property, friendly, easy to work with. Will definitely hire again! Thanks for your great work as always!"
