"Frangioso is simply the best. We had a tiny project; we were looking for a quartz remnant for a bathroom vanity countertop and they treated us as if we were purchasing ten times that amount. They went out of their way to meet us when they weren’t technically open, walked us through numerous remnants (they had a great selection) and perfectly installed the countertop. I’m a perfectionist and couldn’t find fault with anything. What amazing service and quality in craftsmanship."

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