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 !"

"We had our kitchen and primary suite renovated by Jamaal and his team at Yusra Design and we couldn't be happier with the decision. We really wanted a cohesive process of design phase through the build and the team was beyond our expectations on delivering exactly that. Through the entire process we were in great hands and the communication was excellent. They executed on the timeline that was communicated from the start of the process and the quality of the work and materials was top notch. We love both of our new spaces and would recommend Yusra to anyone that is looking for a competent and thorough team to help build their dream space."

"Nice owner, hack job crew. Hired to replace siding and trim. Manager of the project was fired a few times during work and it really shows. So many small details are either unfinished or poorly done. Amateur cuts on the trim left gaps and old trim was not prep for paint or just left unpainted. They also smeared silicone to cover screws on the front face of the shingles, the whole house looks like it's covered in bird droppings. Plus they also damaged the roof and electrical boxes. Who knows what other things they skipped on, left me with a time bomb of problems that will takes years to show. I would not recommend. "

FAQs for addition to existing structure building service projects in Winthrop, MA

You can typically raise your roof by four to eight feet, depending on your home's structure and roof design. The exact amount depends on factors like roof slope and framing support. Raising the roof creates additional interior space, enhances natural light, and increases your home's value. Consult a professional to determine the feasible height increase for your home.

Yes, you need a building permit to raise your roof. Obtaining a building permit ensures your project complies with local building codes and safety regulations. A professional contractor can assist with the permit and inspection process and ensure all legal and safety requirements are met. Your contractor will be familiar with building codes in your area, which can differ between cities or states.

While it's possible to raise a flat roof, it requires extensive structural modifications. Flat roofs lack the attic space and support structures of pitched roofs, so raising them involves significant engineering to ensure safety and durability. This process can be complex and costly, so professional assessment is essential before undertaking a project of this magnitude.
