# Abacus Building & Remodeling Inc.

**Trade:** General Contractor / Remodeling · **Phone:** (774) 482-2127 · **Website:** https://www.abacusbuilding.com/ · **Languages:** English

**Rating: 3.6/5** (low confidence) — from 1 reviews across 4 sources.

## The honest read

Abacus Building & Remodeling is a Brewster-based general contractor run by Scott Collum, who is also the on-site project manager; the company describes itself as family-owned and says it has served the Lower Cape — including Orleans, Harwich, Chatham, and Provincetown — for over 25 years, specializing in custom home building, additions, and remodeling, including historic building work.

Scott's Massachusetts construction supervisor license is active. The company's website also lists a home improvement contractor registration number, though that one hasn't been independently verified.

The only written review on file is from 2024: a homeowner said Scott made the process seamless, praised the team's skill and attention to detail, and said the job finished on time.

With just one review to go on, there isn't much of a track record yet to draw broader conclusions from — worth asking Scott directly for references from recent projects before committing to a larger job.

**Strengths:**
- Verified license — Massachusetts construction supervisor license is active
- On-time delivery — one reviewer praised a smooth, on-schedule project
