# J J Delaney Inc

**Trade:** General Contractor / Remodeling · **Address:** 20 Rascally Rabbit Rd #2, Marstons Mills, MA 02648 · **Phone:** (508) 420-6855 · **Website:** http://www.jjdelaneyinc.com/ · **Languages:** English

**Rating: 3.5/5** (low confidence) — from 0 reviews across 5 sources. A 0–5 star rating built from what customers and the public say (every review and mention weighted by where it was posted, how old, how detailed and how credible it is, shrunk toward a 3.5★ baseline when evidence is thin) plus what the record shows (Reddit recommendations or warnings, a registry-verified licence, how recently they were reviewed, customer work photos, BBB grade, negative news, a revoked licence). Positive record counts only as far as the reviews have earned it; penalties count in full. Confidence describes how much weighted evidence stands behind the number, never the number itself: low when fewer than about five normal reviews' worth of weight (or mentions only) support it, medium up to about twenty, high beyond that across at least two sources. An operator flag for a suspicious review pattern caps a rating at 3.5★ and marks it low.

## The honest read

J.J. Delaney, Inc. is a Marstons Mills custom home builder and remodeler working the mid-Cape — its own site also describes landscape design, property management and a real estate brokerage arm under the same roof. The company is led by Jack Delaney, with Gilman Martiny as project manager; the "40 years of experience" on its Houzz page describes Jack's personal career rather than a company founding date.

The work on display is the high end of Cape building. Its Houzz profile posts four projects — a Hyannis Port new construction, an Osterville kitchen remodel, and a Cotuit demolition-and-rebuild among them — and an architecture write-up credits the firm alongside LDa Architecture and Interiors, Kennerknecht Design Group and Horiuchi Solien Landscape Architects on a family home on Salten Point in Barnstable. In 2014 it took a BRICC Bronze award for best new single-family home under 2,500 square feet.

What you won't find is customer commentary: there are no reviews on Houzz or anywhere else, so the public trail is project portfolios and professional credits rather than homeowner accounts. Houzz lists a Construction Supervisor licence, CS-009961, though that is the directory's claim rather than a registry check.

A fit for custom builds and substantial remodels in the Barnstable–Mashpee area — ask for recent client references and confirm licensing directly, since neither is on the public record yet.

**Strengths:**
- Award-winning build — 2014 BRICC Bronze, new single-family home
- Architect collaborations — credited with LDa Architecture on a Salten Point home
