A 2024 customer said the company delivered their home in just under 10 months from contract to closing, after more than 50 change orders to the signed contract. That 2024 customer also said Greg kept everything on or ahead of schedule. On its BuildZoom profile, the company says it was founded in 2009 and serves Danbury, Brookfield, Newtown, Southbury and surrounding areas, with help on land acquisition, design, construction and house renovation. A 2025 customer who decided to build a new house said they put their trust in Greg Carnrick, and that Greg's team, especially Dan, helped them make choices in customizing it. In 2024, a customer who described taking on "quite the project" said Greg was available to answer questions or stop by after they moved in. A 2023 reviewer who has had a business relationship with Greg Carnrick for almost 10 years said they awarded GRC Construction the contract to build a new home for them on Candlewood Lake. A 2023 BuildZoom reviewer said Greg listened to what they wanted and worked with them on the little things throughout the build. **Strengths:** - Many change orders — a 2024 customer made over 50, delivered under 10 months - Design choices — a 2025 customer said Dan helped customize their house - Help after move-in — a 2024 customer said Greg answered questions afterward ## Claims & citations Every claim below is backed by real evidence rows — uncited claims are dropped in code before publication. - 4.7 stars from 12 Google ratings _(confidence: high)_ - [Google](https://www.google.com/maps/search/?api=1&query=GRC%20Construction%20LLC&query_place_id=ChIJf0WXfjOut08RsYkmer_ObQc) — “Google: 4.7★ from 12 ratings” - BBB grade of A+ _(confidence: high)_ - [Better Business Bureau](https://www.bbb.org/us/ct/sandy-hook/profile/custom-home-builder/grc-construction-llc-0111-110093873) — “Better Business Bureau grade: A+” - Says on its BuildZoom profile it was founded in 2009 and serves Danbury, Brookfield, Newtown, Southbury and surrounding areas _(confidence: medium)_ - [BuildZoom](https://www.buildzoom.com/contractor/grc-construction-llc-ct) — “About (BuildZoom profile, verbatim): Founded in 2009, GRC Construction LLC is licensed for both remodels and new home construction.
