Wow Construction LLC

Eleven of the 41 written accounts about Wow Construction describe a bathroom — gutted, retiled, re-plumbed, or in one 2023 review built from nothing but examples and back in service four weeks later. The Braintree company describes itself as a design-build shop: custom homes, renovations, additions, interior design and built-in storage across Greater Boston and the South Shore, founded and led by Sam, who the site calls an architectural designer and master craftsman. Most reviews name Sam himself — walking a homeowner through structural options for a leaning front porch in a May 2025 review, handing over an itemized quote with the charges broken out in a 2023 review, checking his crew's work each day on a 2022 kitchen tile floor. Outdoor structure is the other steady vein: nine accounts cover decks and porches. A 2023 reviewer described a back deck done in 2020, a 5x16 cement slab rebuilt as a 10x26 pressure-treated deck. A September 2024 reviewer had front entry stairs taken from brick to Trex composite decking and PVC railing. A 2022 reviewer had treads and rails on two small decks swapped for composite. One account runs against the rest, and it is the one to raise before you sign. In a January 2025 review, a homeowner wrote that a master shower built three years earlier had a curb that failed from water leakage and separated, causing severe water damage, and that the curb was saturated and full of mold — and that Sam was nowhere to be found. Two 2023 reviewers describe the opposite handling: one found deck screw plugs sticking up and the owner came out himself; another, gut-renovating a 1975-era bathroom, wrote that errors and omissions were addressed and fixed quickly. BuildZoom's profile lists a home improvement contractor registration for the company along with other Massachusetts license-board entries, and shows 41 of its projects; the state's register is where to confirm the registration yourself. The company's site offers free estimates. For a bathroom gut, a deck or porch rebuild, or an addition where one person has to hold the design and the trades together, this is a Braintree outfit with five years of written history doing exactly that. Ask how callbacks are handled once the final payment clears, and get the shower waterproofing — pan, curb, membrane — spelled out on the contract.
