Meet Mateus Magno.
Licensed builder, certified project manager — and the person on your side from the first idea to the final walkthrough.








You have the vision. I make sure it gets built.
Magno & Co is a Massachusetts construction company based in Somerville. I came up through the trades — framing, finishing, building things with my own hands — and then learned to run the whole job: budgets, schedules, permits and the crews that make it happen.
Today I step in where most projects get stuck: between the idea and the finished space. Whether you bring finished plans or just a vision, I turn it into a plan, price it, pull the permits under my license, and manage every trade and inspection as your representative — until the project is 100% complete. To date I've renovated and managed over $3 million in projects, from a 3,747 sq ft whole-house renovation in Essex to kitchens, bathrooms, decks and a commercial salon build-out.
I hold an unrestricted Massachusetts Construction Supervisor License, I'm a registered Home Improvement Contractor and a certified MA Lead-Safe Renovator Supervisor, and I'm certified in project management through Buildertrend and Google. I speak English, Portuguese and Spanish, so nothing gets lost between you, your designer and the crew.
Credentials you can check.
What you can expect.
I work for you
My job is to protect your budget, your timeline and your vision — on every decision.
A written plan
Scope, price and schedule in writing before we start. No vague line items, no surprise change orders.
A livable home
Dust contained, finishes protected, lead-safe practices, site cleaned daily. You keep living in your house.
100% complete
I don't walk away at 95%. Inspections, punch list, documents — finished, and I stand behind it.
Somerville, Cambridge & Greater Boston.
Not sure if you're in range? Just ask — if I can't help, I'll point you to someone who can.

Let's make your vision real.
Free consultation, honest advice, and a clear written budget and schedule — then I take it to 100% complete.
