We specialize in patios, walkways, stone walls, steps and more.

"From the moment I submitted the request through Angi to the end of the project, this company was responsive and transparent throughout the entire journey. The concrete holding our front steps together was eroding, which caused water to seep in and create pockets under the granite slabs. The steps were literally coming apart. Additionally, our front wooden threshold leading into the home was rotting. Blue Bones Construction did a beautiful job restoring the steps and replacing the rotted threshold. They arrived on time, cleaned up after themselves, and the work was high quality. I would definitely recommend this company."

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"

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.
