Ryan Sinclair Stoney
Sole Owner
Exceeded Expectation
*Superior Skill and Talent
Ryan Stoney and crew, Lewis and Nick, are true craftsmen
-They used a Laser Level to assure that their tile is laid with precision accuracy.
-They sculpted the edges of quarter round as if it were a piece of art framing in the flooring
- Ryan researched crown moulding & wooden framing to find the perfect match to the rest of the house
-Ryan identified major hazards leftover from a previous and subpar contractor, then proceeded to help us fix the botched work without gouging or taking advantage of the situation
-Ryan's meticulous eye for perfection has transformed our previously botched remodel into a work of art.
*Reliable and Trustworthy
-Ryan was always on-time and showed up to work everyday without fail
-Ryan provides detailed and clear invoices that leave nothing up to question
*Excellent Customer Service and Communication Skills
-Ryan communicated any issues and concerns he had, then explained in detail our options and costs
-Ryan and team, Lewis and Nick, were a pleasure to have inside my home. They were kind, thoughtful and clean. I have two small children and they were incredibly respectful and did not use crude or foul language around my family, they are clean cut and genuinely awesome men. My husband and I are excited to have them come back to redo another bathroom!
Personal note: I consider myself incredibly lucky to have found Sinclair Builders. It's rare to find this level of quality, knowledge, and expertise.
