Locally owned business with over 12 years of experience. Custom Paver Patios, walkways, retaining walls, and driveways. We also offer full clean up landscaping, hardscaping, and stone work. Passionate about serving our local community and continuing to deliver great customer service. Feel free to call or text with questions regarding your projects. Look forward to working with you on all your home endeavors.

"M&L Landscaping Construction is absolutely incredible! You will not regret hiring Leo and his team for your project. I first hired Leo for one job, and after seeing the quality, precision, and care in his work, I immediately brought him back for a second. The first project included pavers, a retaining wall with built-in seating, a garden bed, patio/paver installation, fence installation, and a composite deck with stairs. The second project was for my rental property and involved an insurance claim to repair the facade of the house. That work included installing stone veneers on the front of my home, constructing a new deck with a roof, building a stone wall with fencing, and completing a blacktop driveway. What truly sets M&L apart is not just the beauty and craftsmanship of their work, but the professionalism, organization, and integrity behind it. Leo’s team is respectful of your property, punctual, and incredibly hardworking. They take pride in what they do and it shows in every detail—from layout precision to cleanup after completion. Equally impressive is how Leo manages the business side of things. He’s communicative, transparent, and extremely reliable—qualities that are rare to find in the contracting world. He provides clear timelines, fair pricing, and proactive updates, so you always know where things stand. Having worked with many contractors over the years, I can confidently say that M&L Landscaping Construction is top-notch from start to finish. I was so impressed that I even referred my parents for their driveway paver installation—and, just as expected, it came out beautiful. If you’re looking for a trustworthy, skilled, and professional landscaping and construction team, hire M&L Landscaping Construction. You’ll be glad you did!"

Carpenters, Plumbers, Electrician, Plasters and All license professional and Insured.. 100% Job guaranteed.

"Pedro and his team were excellent. They were professional and timely, hard-working and meticulous, and trustworthy. Best of all (at least for me), is that Pedro is VERY responsive and his team is assigned to get your job done and done correctly. They show up on time every day, and were willing to work late into the evening to hit the project milestones. Pedro was 100% clear about the costs, and he made sure I fully understood the areas where the costs were not known or where the costs could possibly change. For example, he said, "If you open up this wall, I'm not sure what we are going to find." I told him to proceed and his team opened up that wall and found that the previous contractor had installed literally zero insulation. Pedro met with me, reviewed what his team had found, went over all of our options, gave me his recommendation, and only proceeded when I completely approved the additional work that would be done and the additional cost entailed. Pedro is a true partner and his team does great work. I cannot recommend them enough. My wife and I have already booked them for another job renovating a first floor porch and creating a roof over the open-air second floor porch."

Jeff Veglia Remodeling was established in 1987 offering full scale remodeling and tile services. This business was built on honesty, integrity, and quality to all clients. Our reputation is based on superior quality at a competitive price and most importantly we listen to our customers. We serve Massachusetts. Please email or call rather than Message Center on Angie's List.

"Veglia Remodeling was wonderful to work with. Jeff gave me an estimate for the labor/work on my bathroom remodel. He also suggested vendors to work with and suggested meeting them to choose materials (which was the other cost of course). That was very helpful. Jeff was always available via text or phone. Mostly text. He was the point person if I had concerns. Always gracious. Happy to weigh in if I wasn't sure about something. He has a number of people who he works with and they were all very professional and everyone always cleaned up when they left for the day. I felt very fortunate to have Jeff commit to my project since my bathroom is extremely small (two people standing in it is a crowd) and it can be tough to find someone who will work on a small project."

Call us Today!!! With over 100 years of combined experience D & R Construction offers a wide range of residential and commercial services. Our focus is on client satisfaction and providing high quality work at a fair and affordable price. Many construction companies have a set hierarchy where owners, project managers, and employees each fall within their respective category. Here at D&R we challenge that hierarchy set up. The owner gets just as dirty as the laborer, and the carpenter gets to know the client just as well as the owner. At D&R we all work together to be the BEST decision a homeowner ever made! We look forward to earning your business.

"In 2021, I hired Eric to fix a water leak in my basement. I paid approximately $8000. Three months after the work was done, there was leaking again. He came over and told me that this was a different leak. After I saved up enough money, I was referred to an expert in basement leaks/foundations. He came over and completed the work. When he was doing the work, he proactively asked me who did the work previously. He said he was clearly not done by someone with knowledge of foundations. I have tried to resolve with Eric. At a minimum, I deserve a refund"

"I hired Long Roofing Products to replace my roof. From the beginning the sales man lied to me, telling me that they could take off my Gutter Helmets and put them back on correctly. This was lie #1. They have null and voided the warranty of my gutter helmets, because they were not supposed to touch them and according to Gutter Helmets all the roofers know this. lie #2 there were missing pieces on the ends of my gutter helmets to prevent the birds from getting into the gutters. The salesman told me they would order the piece from Gutter Helmets and replace it. This was never done. I have contacted them several times and they continue to tell me they will fix it and they never do. I would NEVER recommend them, I would only tell you NOT to use them. They talk a big game but never follow thru with their promise's."

FAQs for second story addition building service projects in Chelsea, MA

For many homeowners, building up is worth the expense because it provides the extra bedrooms or living areas that can’t be accommodated within the existing footprint. A larger, updated home often commands a higher resale price, recouping a sizable share of the project cost while allowing you to stay in the neighborhood you love. Run the numbers with a real estate agent and contractor to ensure the expected return and day-to-day benefits align with your goals.

Whether it makes more sense to build up or out depends on your lot, budget, and local code. Building up preserves yard space and involves less foundation work, but you may need to vacate the home during construction. Building out avoids staircases and can proceed while you stay put; however, it encroaches on the yard and may face setback limits. Compare both options with your contractor before making a decision.

A structural engineer will first inspect the existing foundation for cracks, footings, and load capacity. Depending on the findings, the crew may pour new concrete footings, install steel or concrete piers, add reinforced beams, or tie additional rebar into the slab. These upgrades redistribute the weight of the new floor and bring the structure up to code. Your contractor will outline the specific reinforcement plan and timeline once the engineering report is complete.
