## The honest read

Duffy Construction Building & Design is a Cummaquid remodeling and home-improvement contractor run by Brian Duffy, specializing in traditional Cape Cod additions, whole-home remodels, and kitchen and bathroom renovations. The company describes itself as serving Cape Cod for roughly 25 years, though its own website gives two different start years -- 1995 in one spot, 1996 in another -- and its Angi profile carries a '31 years of experience' badge that doesn't match Angi's own About text of 'more than 15 years,' so take the exact tenure with a grain of salt; what's clear is this is a long-running local operation. Public building-permit records list 14 historical permits filed under Brian Duffy's name, including one at the company's own Cummaquid address, which lines up with the identity on file.

The written reviews are sparse but strongly positive and span a long stretch. In a 2010 Angi review, a customer called a full rebuild a wonderful experience with good communication from Brian and his wife. More substantively, a 2021 review describes a customer who hired the company for three major remodeling projects over roughly a decade at a Cape Cod second home, starting with a redesign that transformed a 1,400-square-foot cottage. Houzz and Angi both list additions, kitchens, new homes and bathroom work among the company's services, and Houzz's own profile notes it hasn't collected any reviews there yet.

There isn't much written detail here beyond those two accounts, so it's worth asking for references from recent projects and getting the company's actual years-in-business straight before signing on -- the underlying work described, though, has held up well enough to bring the same customer back three times.

**Strengths:**
- Long-running client relationship — a 2021 review described three major remodels over a decade
- Warm early review — 2010 Angi review praised communication and full rebuild
- Verified permit history — 14 building permits filed under the owner's name

**Concerns:**
- Unclear years in business — website and Angi give conflicting tenure claims

**Where sources disagree:**
- The company's own website gives two different start years for the business -- 1995 in its tagline, 1996 in its body text -- while also claiming 'over 25 years' in business
- Angi's profile carries a '31 years of experience' badge that doesn't match Angi's own About text describing 'more than 15 years'
