# Bottom Up Builders **Trade:** Windows / Siding / Gutters · **Address:** Randolph, MA · **Languages:** English **Rating: 3.8/5** (low confidence) — from 5 reviews across 2 sources. 100% of sentiment-scored reviews read net-positive. Last 6 months: 2 reviews, 0 negative. ## The honest read Bottom Up Builders is a Randolph, MA carpentry outfit run by Jason Puopolo, who says he's spent 25 years in carpentry, roofing, siding, and window and door work before running his own six-employee shop for the past six years. Deck work is what keeps coming up: in 2022 reviews, two homeowners described full deck renovations — one composite deck extended and rebuilt through rain and past sunset, the other completed with patient, detailed communication throughout. A more recent review, from June, praised a stairs-and-balusters install finished quickly and described as going above and beyond expectations. Reviewers across both eras single out the same thing: Jason walks customers through their options himself and stays responsive from the first call to the final job. It's a solid call for deck, stair, and general carpentry work in the Randolph area; ask directly about current pricing and lead times for roofing, siding, window, or door jobs, since the reviews on file are mostly about deck and stair carpentry. **Strengths:** - Deck craftsmanship — 2022 reviewers praised full deck renovations - Responsive communication — reviewers cite clear, patient updates throughout - Fast turnaround — a 2026 review praised a quick stairs and balusters install ## Claims & citations Every claim below is backed by real evidence rows — uncited claims are dropped in code before publication. - Thumbtack rates the business 5.0 stars from 9 ratings _(confidence: high)_ - [Thumbtack](https://www.thumbtack.com/ma/randolph/custom-dog-house-builders/bottom-up-builders/service/443647764847968277?spotlightWebMarkupEnabled=1) — “Thumbtack: 5.0★ from 9 ratings” - A June 2026 reviewer praised a fast stairs-and-balusters installation that went above and beyond expectations _(confidence: high)_ - [Thumbtack](https://www.thumbtack.com/ma/randolph/custom-dog-house-builders/bottom-up-builders/service/443647764847968277?spotlightWebMarkupEnabled=1) — “Bottom up builders did such an amazing job installing stairs/balusters for us!
