After a storm my roof started leaking. There was water coming through the ceiling. It was a Sunday morning . Demi came over that morning to check it out. He gave me a fair price. By Wednesday the roof was fixed. He was on time and professional. I would recommend this company.

My experience was very positive. Demi was very professional and responded quickly to my concerns. He shared photos from my roof pointing out the problematic area. After job was completed he took more photos to compare before and after. I will certainly reach out to Demi for future home repair needs.

Demi was excellent! He fixed my leaking pipe in about 20 minutes. He was very skilled, experienced, and knew exactly what the problem was right away. The price was very reasonable, and the whole repair was quick and professional. I really appreciate his great work and highly recommend him to anyone who needs plumbing services!

Demi is incredible. He is incredibly kind, transparent, and honest about his work. He worked to not just evaluate our project for what we felt was necessary, but he also educated us on his professional suggestions for improvements for our home that made the most sense. From the moment that we met him we appreciated him, his approach and his guidance. When we shopped around, we received a quote that was slightly lower than what he had quoted us, we approached Demi and he met us at the price point that made us comfortable to proceed. He and his team showed up promptly and completed our project with precision, quality and impressive speed. We couldn’t be happier with his work, and we are happy to recommend his services.
