We are a family owned and operated home improvement company with over 20 years experience. We specialize in kitchens, baths, and basements Our commitment to you is: Quality work at an affordable price with personalized attention to your needs.

"From time I read his reviews of other's I couldn't wait to meet JERRY. After having weekly consultations we were convince we made the right decision without meeting with anyone else. His ideas and suggestions matched our thoughts perfectly. There was no rush on his part for us to make a quick decision. Our original idea was to only have a center island installed and possibly refurbished our 45 year cabinets. But his price quote and latest design in cabinets, plus removing an existing wall that separated the dinning room and kitchen will provide more light and space, plus it will upgrade our home to more of a modern look. To meet a contractor unknown for the first time it was a joy to have chosen DAUGHTRY CONSTRUCTION."

"Brian and his crew did a great job on our bathroom. We had it completely remodeled not just renovated from the walls, the ceiling, the floor and all plumbing fixtures totally removed and replaced. They were very helpful and worked with us on the changes we had requested even after work had started. The project took a little longer than expected but our house was built in the 1900's so it took a little more TLC than most. We were happy with the end results."
