"Roberto and his crew did an outstanding job! We usually do all of our hedge abs shrub trimming ourselves, but with a few other projects going on we hadn’t gotten them all season long and they were seriously overgrown. Since we COULD do it ourselves, we had a limit on what we were willing to pay, so we were getting several quotes … most of which were higher than we had hoped. Roberto worked with us on the pricing, which was good news because now it was off of our plate! His crew was there the early next day … fast, friendly, courteous, conscientious and neat! We are now looking to have Roberto and his crew back to take a few more projects off of our plate too! If you want a great job, at great price, by a great crew … we highly recommend Roberto’s Affordable Lands aping!"

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."

American Precision was founded by Estenio Lima and Sara Yoffe. Estenio is a licensed construction supervisor and skilled master carpenter who has built, renovated, and restored some of the most beautiful homes in Massachusetts. Sara, the daughter of a contractor, is a lawyer by training and holds both a construction supervisor and real estate broker license. She began her career in real estate and construction in 2018, first by focusing on her family’s portfolio of properties. Sara manages over 150 homes and apartments in Cambridge, Charlestown, and Quincy. Estenio and Sara began collaborating in 2018, developing properties for APD's sister company, Cambridge Prime, and started American Precision in 2021. American Precision specializes in renovation and restoration of existing properties to fit the needs of both homeowners and developers.

"We had the pleasure to work with American Precision Developers over the last 2-3 years. They worked on three separate large projects: (1) a main-level kitchen, dining and living room remodel, (2) basement refinish and mudroom rebuilt (3) bathroom, primary bedroom and family room remodel. Both Sara and Estenio listened carefully to our needs and preferences and offered suggestions based on their experience and desire to provide a high-quality finished product. The craftsmanship and attention to details in the finished spaces are truly impressive. On the main level they transformed a boxy layout into a modern, open-concept kitchen, dining and living room. The bathroom, primary bedroom and family room are now beautiful functional spaces tailored to our needs. APD did a great job on waterproofing and finishing the basement and mud room that are now inviting and well-designed spaces. ADP has an amazing team. We highly recommend them !"

FAQs for second story addition building service projects in Somerville, 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.
