Exponential Construction Corp is a Framingham, Massachusetts general contractor owned by Jose Andrade, handling kitchens, bathrooms, additions, decks and outdoor living spaces, painting, siding, and masonry patios and stone walls, plus residential and commercial roofing, across Framingham and the surrounding MetroWest and inner-Boston suburbs. One customer traces the relationship back to 2016, when Jose's masonry crew was picked over ten other quotes for a retaining wall, before he later founded the company as a general contractor.
The volume and consistency of praise here is hard to miss: 53 reviews across six platforms from 2021 through 2026, the large majority of them 5 stars, describing everything from full kitchen and bathroom gut renovations to home additions, deck replacements, basement finishing, and repairs after other contractors left a job unfinished. A 2025 review described a major kitchen and bathroom renovation handled professionally start to finish; a 2024 review described a deck replacement and siding repair completed in under three days; and a 2023 review described a large home addition delivered on time, on scope and on budget.
Repeat business shows up again and again in the written record — several customers describe hiring Exponential for a second, third, or even more projects after an initial job went well, including first-time homebuyers who used the company for three separate projects on the same house. Reviewers consistently point to Jose's own involvement and communication as the reason, describing him and his crew as responsive, meticulous, and easy to reach when questions or scheduling changes came up.
The company holds an active Massachusetts home improvement contractor registration, verified against the state registry, and carries an A+ Better Business Bureau rating.
One thing worth a quick question: the company's own web pages describe two different starting points — one saying it has served Massachusetts since 2019, another (the owner's own account) putting the founding in 2015 — so it's worth asking directly how long the current entity has actually been operating if that matters to you.
For a kitchen or bathroom renovation, a home addition, a deck, or a broader remodeling project in the MetroWest area, this is a general contractor with an unusually deep, largely positive review history and a verified state registration behind it.
