Flawless Development & Construction was an excellent choice. Everything from pricing, planning, communication, timelines and building permits went smoothly. Our town has a rather lengthy approval process for building and Flawless came through perfectly in every step and passed all inspections the first time though. Our finished double deck came out better than expected. We've received many compliments on the new construction. We have other projects to do for our house and will gladly work with Flawless again. Excellent all around!

About Flawless Construction & Development
Welcome to Flawless Construction & Development! Before reaching out, please read this carefully: We invest significantly in every lead, so we kindly ask that you do NOT request an estimate if: • Your project budget is under $10,000 – we are currently focusing on larger projects. • You’re simply collecting quotes with no clear intention to proceed. • You’re not planning to move forward within the next 3 months. • Your main deciding factor is price – we focus on delivering value, not being the cheapest. At Flawless Construction & Development, we’ve built a strong reputation with 120+ verified reviews and over 450 hires on Thumbtack because we believe communication and transparency are the foundation of a great customer experience. We don’t need to mention quality — because for us, quality is the bare minimum. We are fully insured with Liability and Worker’s Compensation, and properly licensed with both Home Improvement Contractor (HIC) and Construction Supervisor License (CSL). All of our crew members are trained and certified under OSHA and Lead Safety regulations to ensure a safe and professional job site. Our pricing is competitive — not the cheapest, but fair — reflecting the structure, safety, and support we offer to provide you with the best possible experience.
Reviews
The porch came out great! Everything looks fantastic. Murilo and his team are easy to work with, and responsive.
Outstanding at every stage. Competitive pricing incredibly well made proposal. Though the reason I'd recommend Flawless 1000x over is the quality of work and attention to detail. Even the inspector was impressed. Fantastic job and a very honest business I will be working with them again
We recently had Flawless Construction help us with some Ipe wood deck repairs, cleaning, and re-finishing/painting. It looks beautiful! They breathed new life into the look of our deck. It's important to mention how pleasant the entire experience was. Communications was pro-active, personalized, and timely. The team had me check the work and did not stop until I was happy with some final details. That is the level of professionalism and service I loo for and FC delivers.
We hired Flawless Construction (Murilo Vieira) to install a TimberTech Prime+ Coconut Husk deck at our home in Burlington, MA. The experience was extremely disappointing. The project took more than double the expected time, failed three inspections, and caused damage to our home (Subcontracted electrician drilled a hole through the exterior wall and through interior plaster wall requiring hole repair and repainting). The work was partially completed by subcontractors, which contributed to inconsistent quality and lack of oversight and there was no general contractor on site which were both outlined specifically in the contract. Shortly after completion, the deck showed defects like chipping and splitting. A TimberTech senior specialist reviewed the installation and confirmed it was not done according to manufacturer specifications, including incorrect fastening systems, improper fastener placement, and missing structural support. We gave the company an opportunity to fix the issues under a formal remediation plan, but the second attempt was also done incorrectly, with continued structural problems, poor workmanship, and additional damage. We ultimately terminated the contract and now must pay to have the deck rebuilt properly. We have extensive photo documentation of both the original installation and failed remediation. We hired him because of all his 5 star reviews and his many promises, but do not hire for decking projects.
Flawless Construction is one of the best companies I've worked with - relable, efficient, high-quality, conistent, respectful. Every person we interacted with seemed to genuinely want to do their best and this showed in the quality of the final product - a beautiful new deck at a fair value, that was built quickly and passed inspection with compliments from the building department. After working with many contractors on different properties, I can say that Murilo runs this company as if he is building it to fill the dire need for reliable trully trustworthy construction businesses that put the interests of their clients first. I am planning to hire them again.
Murilo and his team did an amazing job on our renovation! The job was a full basement finishing with a full bathroom and laundry that has added so much functionality to our house in Salem, NH. Murilo was great to work with and from the beginning was accommodating with our budget, some building constraints, and some quirks from the original home. In planning, he suggested changes to scope that ultimately fit our budget and shared a layout early on. We worked with him on upgrading our original plan to get a full tiled shower and he was able to problem solve our radon meter and water main to be fully accessible. He also helped us troubleshoot some issues we had with ice dams from the harsh 2025-'26 winter that threatened the project. He was available every time we needed and made the project run as smooth as possible, and even helped through slow inspections through our town. His team was super helpful with the day-to-day work. They brought us into any decisions, but generally they were quiet and unobtrusive to our everyday. Very friendly and helped to make suggestions on materials or how to install things that would meet our expectations. A few of them helped me dig out after all the snowstorms that year! Great team, great final product. The project added so much functionality and value to our house since it was so well done.
We recently had our basement finished with Flawless construction, and we couldn’t be happier with the results. From the initial consultation to the final walkthrough, the entire process was smooth and well-organized. The team was professional, punctual, and patient to work with. The quality of workmanship is excellent — clean finishes, great attention to detail, and everything was done exactly as discussed. Any questions or small changes we had along the way were addressed quickly and professionally. The crew kept the space clean and respected our home throughout the project. In fact, the team’s recommendations for the overall basement design and layout helped us design it even better for a toddler-friendly play space. Their input was thoughtful and practical, and it made a big difference in how functional the space turned out. Our basement has been completely transformed into a beautiful, functional living space. We would highly recommend Murilo and his team to anyone looking for basement finishing or home renovation work.
We recently completed a major renovation of our first single-family home with Flawless Construction Company, and we couldn't be happier with the results. Murilo, the owner, and his team were professional, dedicated, and a pleasure to work with throughout the entire process. One of the things we appreciated most was Murilo’s willingness to listen to our input and adjust the project details accordingly. He genuinely cared about our vision for the home and made sure it was reflected in the final outcome. Fixing the flooring on our second floor turned out to be a much more challenging task than anticipated. It required extra time and effort, but Murilo and his team handled it without a single complaint or request for additional charges. They simply got the job done — and did it perfectly. Now that we’ve been living in our renovated home for a few weeks, we can confidently say the quality of their work holds up. This review comes from real, lived-in experience — and we’re extremely satisfied. We highly recommend Murilo and Flawless Construction to anyone looking to turn their house into their dream home.
Our new deck surrounding our pool is gorgeous. Its quality work done right.
I used Flawless construction for getting fence installed. Murilo, Iago and the crew did an amazing job putting up the fence. They were extremely professional, polite and did an incredible job. Due to some issue I had them move the fence and they worked through it without hesitation or asking me to reschedule the job. The crew worked almost 12 hours everyday for 5-6 days to get the project completed. They arranged all the material so as to not make a mess and also cleaned up every night. Would definitely recommend them for your construction needs.
I hired Flawless Construction for some hardscaping work. They quickly demolished my old deck and installed new granite stairs with a beautiful stone veneer around them. The crew was respectful and worked consistently from start to finish, only pausing on rainy days. I’m very pleased with the final result and would definitely recommend them.
We would definitely recommend Flawless Construction. Murilo responded to our job right away, was very easy to work with, and worked within our budget. His crew was polite and professional, arriving early and working throughout the day. We could not be happier with the results. Before and After
I just wanted to drop a huge thanks to Murilo and his team for the fantastic job they did finishing my basement. It looks amazing with the new bathroom, two windows, and all the walls and floors sorted out. He and the team have always been reachable and ready to listen and understand my needs. Also, be patient to deliver a quality job. Your attention to detail and how you stuck to the schedule really made the whole process smooth. I’m super happy with how everything turned out. You and your team rock! I’ll definitely recommend you to anyone looking for renovations, and I’m looking forward to working together again in the future.
We had a great experience working with flawless construction. We are happy with our basement remodel project. The work quality is fantastic with great value! We will definitely go with them for any home improvement projects.
This company of remodeling construction experts were right on point!
Very detailed quote with walking through all the steps of the project, and great suggestions to make our basement improvement perfect.
Exceptional !! Murilo, Luigi and their team are simply the best. I got multiple quotes to finish the basement, put in recessed lights and replace the front door. Out of handful of quotes, Flawless quote stood out not only in $ terms but also in process, communication and scoping. Glad, I choose Flawless. There were few changes to initial contract but Murilo was quick to bring those to my attention with scoping. He and his team went above and beyond in delivering best output. They are polite, easily reachable and puts lot of efforts to understand what you want and do the work with outmost dedication. The cleanup process they follow after every day(literally every day) work is worth mentioning. I high recommend Flawless if you are planning any kind of renovations.
I can't say enough about the amazing job Murilo, Luigi, and their team did in refinishing our basement. From beginning to end great customer service and they answered all our questions promptly during the project putting us at ease. We highly recommend them and would work with them again.
All around outstanding! Professional, communicative, thorough! Murillo was very transparent about pricing and the process. They started and finished on time! Has that ever happened in the history of home renovations?! A miracle! It was as if they renovating their own home. It was obvious to me they wanted everything done properly start to finish. I really can't recommend them highly enough. You will feel very pleased.
