# 4 Base Design And Development **Trade:** Carpentry · **Address:** 108 Illinois St, Worcester, MA 01603 · **Phone:** (508) 292-3448 · **Website:** https://www.4baseconstruction.com/ · **Languages:** English **Rating: 3.4/5** (low confidence) — from 2 reviews across 2 sources. ## The honest read 4 Base Design and Development is a Worcester contractor whose Thumbtack profile lists carpentry, remodeling, painting, decks, fences, doors, windows, cabinets, and related residential and commercial work. Thumbtack lists four years in business and 30 project or media items, while the Massachusetts registry shows an active Home Improvement Contractor license under the related legal name 4 Base Design & Development LLC. In 2023, two Thumbtack reviewers described positive experiences. One review, explicitly labeled as a sample review, describes a new-home design and construction process with multiple options, progress updates, and a finished home. Another homeowner praised a new deck, daily cleanup, and the team's workmanship. The history is small and older, with two ratings from 2023. Before booking, ask for current references and confirm the exact scope, schedule, and trade coverage. The active HIC license is a useful credential to verify directly with Massachusetts, but the limited and dated review record means current performance is not well established. They may suit homeowners seeking carpentry, deck, remodeling, or finish work who are prepared to clarify the project details and request recent examples. **Strengths:** - Deck workmanship — 2023 homeowner praised completed deck - Worksite cleanup — reviewer cited tidy daily cleanup - Broad carpentry — Thumbtack lists multiple carpentry services **Concerns:** - Review depth — only two ratings are available - Review wording — longer 2023 entry calls itself a sample review - Review recency — both available reviews date to 2023 **Where sources disagree:** - The longer March 2023 Thumbtack review explicitly says it is a sample review. - BuildZoom and the state registry identify the legal holder as 4 Base Design & Development LLC, while the public Worcester listing uses 4 Base Design And Development. ## Claims & citations Every claim below is backed by real evidence rows — uncited claims are dropped in code before publication. - Thumbtack lists four years in business, residential and commercial work, and 30 project or media items. _(confidence: medium)_ - [Thumbtack](https://www.thumbtack.com/ma/worcester/custom-dog-house-builders/4-base-design-development/service/474489661074538496) — “30 project(s) shown on Thumbtack” - [Thumbtack](https://www.thumbtack.com/ma/worcester/custom-dog-house-builders/4-base-design-development/service/474489661074538496) — “Thumbtack lists 4 Base Design and Development in Worcester as a 5.0-rated pro with two reviews, four years in business, 30 project/media ite…” - Massachusetts HIC license 208324 is recorded active under 4 Base Design & Development LLC. _(confidence: high)_ - [State License Registry](https://contractorhub.mass.gov/s/hic-contractor-search) — “MA hic license 208324 registry-verified active — registry holder of record: 4 Base Design & Development LLC” - A 2023 homeowner praised a new deck and daily worksite cleanup. _(confidence: medium)_ - [Thumbtack](https://www.thumbtack.com/ma/worcester/custom-dog-house-builders/4-base-design-development/service/474489661074538496) — “5★ I’m so happy with the service I received with 4 Base design, Guilherme and his team did an amazing job.
