Customers say: True professional

"I recently hired Luke to remove asbestos-containing linoleum from the original hardwood floors in my home, and I couldn’t be more impressed with the results. From start to finish, his professionalism, attention to detail, and respect for my home was outstanding. He handled the asbestos removal safely and efficiently, keeping me informed throughout the process. The final result blends seamlessly with the rest of the home, preserving its character and charm. The floors now look absolutely priceless, as if they were always meant to be showcased. If you’re looking for a skilled, reliable, and detail-oriented professional for asbestos flooring removal, I highly recommend Luke. His work truly transformed my space."

"I was selling my home and he was one of the people who gave me an estimate, which was far below the competitor's and he walked me through the process that this would entail, he just didn't come by and said "ok this is how it's going to be and this is how much you'll pay", he actually spent time with me and explained everything, worked with me to finish the job promptly and I am happy with the outcome!"
