"We're in process of getting bids on a deck/exterior office space remodel. They were very responsive to our initial request, and we talked to one of the owners of the company via phone and in person within 7 days of our outreach. The project is probably too small for their level of services, but we will definitely consider using them for a future, more complex interior home renovation. They were very nice and giving of their time and expertise, and their build process seems very professional and polished. We had an excellent experience with them."

"David and his team were professional, diligent, creative and prompt. They immediately identified the issues and guided us from design through permitting. He went above and beyond and we couldn’t recommend any higher."

"I contracted with Quality Improvements to build a large deck. The build site is on rough sloping terrain. Mr Mariano Siles oversaw the project and in fact did most of the work. He was very personable and patient in explaining to me the challenges and his proposed solutions. His exceptional attention to detail resulted in a beautiful 400sf deck built to code and absolutely level. I would enthusiastically recommend Quality Improvements to anyone."
