"I hired KJ Drywall to frame, insulate, and sheetrock/texture a basement bedroom. Kevin did a great job. He was very knowledgeable about what needed to be done. He worked very hard and completed the job in a good time. He seems pretty efficient. We had a plumbing issue during his work, and he had someone out to fix it within about 45 minutes. The repair was made in Avery professional manner. Long story short, this fellow and his help were very good to work with, very fair with the price, And Kevin seems like just a really good guy. Glad to have worked with him."
