Murilo Vieira's crews get asked back. In a July 2026 review, a homeowner said the team returned to correct a minor fix on a deck they had installed the year before; on Thumbtack in May 2026, a customer who had a sunroom torn out for a new deck wrote that when there was an issue with the concrete, the crew came out again and replaced it. Flawless Construction & Development is a remodeling and construction company whose own site says it covers Middlesex, Essex and Worcester counties, gives free estimates, and carries a three-year workmanship warranty. Decks and porches are the job described most often. A July 2026 customer had an old deck demolished and replaced with a paver patio and granite steps; another that month had an elevated deck built around a tree; a June 2026 reviewer had Ipe decking repaired, cleaned and refinished. The same crews finish interiors too — a Salem, NH basement with a full bathroom and laundry in April 2026, and a Medford, MA house that took two bathroom additions, a kitchen renovation and hardwood floor installation in February 2026. Bidding moves quickly. A homeowner writing in February 2026 said Murilo scoped the job on a Thursday afternoon, sent a quote that same evening — the best of the three they collected — and started work the following Monday morning. Larger exteriors land here as well: a Groton, MA project in July 2026 covered full stone veneer across the front elevation and metal roofing over the front and back porches, and a September 2025 customer listed roofing, carpentry, exterior painting and copper gutter installation on one house. Google's 45 ratings average 4.9, and Thumbtack shows 4.9 across 200; Thumbtack also lists a Lead Safety certification. One account runs hard the other way. A Burlington, MA homeowner who hired the company for a TimberTech Prime+ deck rated the job one star in June 2026, writing that it took more than double the expected time, failed three inspections and caused damage to their home. A May 2026 customer who bundled a four-season porch, composite deck, paving, a retaining wall, a driveway and landscaping into one Andover job mentioned hiccups along the way. If your project needs permits, ask who schedules the inspections and get the completion window written into the contract. For a deck, porch, paver patio or basement build-out in Middlesex and Essex county towns, this is a straightforward call — the owner is named directly in many of these accounts, and crews have come back when something needed fixing. Before you sign, pin down what the three-year workmanship warranty actually covers.
The porch came out great! Everything looks fantastic. Murilo and his team are easy to work with, and responsive.
We had a great experience working with Flawless on our front porch addition and paver walkway renovation. The owner, Murilo, was very communicative, responsive, and easy to work with throughout the entire process. He kept us informed, answered all of our questions, and made sure the project stayed on track. The workmanship turned out beautifully, and we’re very happy with how the new front porch and updated paver path look. The finished project has made a big difference in the curb appeal of our home. We really appreciate Murilo and the Flawless team for their professionalism and attention to detail. We would definitely recommend Flawless and would hire them again for future projects.

We hired Flawless Construction & Development for a major exterior renovation on our home in Groton, MA. The scope was ambitious: full stone veneer install across the front elevation, metal roofing over front and back porches, complete PVC trim + fascia + soffit + frieze board replacement, new white cedar shingle repainting, exterior door painting, 22 new shutters, 6" seamless gutters, back sliding glass door replacement, back porch ceiling install, front porch railing, back porch railing on granite steps, front walkway paver install, fence replacement with gates, and more. It touched almost every trade — carpentry, roofing, masonry, hardscaping, painting, plus coordination with electrical work happening in parallel. Murilo (owner) ran the whole thing with clarity and integrity. He was accessible on text every day, transparent about design tradeoffs, and creative about accommodating our unusual asks (LED channel spacing in the walkway, PVC doorbell mounting panel, custom soffit lighting prep). When change orders came up — because they always do on projects this size — he explained the reasoning and priced them fairly. He even absorbed cost overruns on his own end without passing them to us. The crew is what really makes this company. Every single person who worked on our project — carpenters, painters, hardscapers, masons — was professional, polite, respectful of our home and our dog, and cleaned up thoroughly at the end of every workday. The workmanship is high quality across the board. When we found small issues during the punch-list walkthrough, they were addressed immediately, no pushback. Timeline: the project ran about as long as you'd expect for this scope (roughly 4-5 months of active work). Progress was consistent throughout, communication frequent, and the final walkthrough left us with essentially nothing outstanding. The result is transformative. Our home looks completely new — like a magazine spread. Neighbors have stopped by multiple times to ask who did the work. We are already planning to hire Flawless again for interior projects next year, and would recommend Murilo and his team to anyone considering a substantial home renovation. Best contractor experience we've ever had.
We recently had our old deck demolished and replaced with a beautiful paver patio and granite steps. The crew was professional, hardworking, and paid close attention to detail throughout the project. The finished patio exceeded our expectations, and we're very happy with the quality of the workmanship. The price was fair, and the entire process was smooth from start to finish. We would definitely recommend Murilo and his team to anyone looking for quality outdoor hardscaping work.
