8 Trades In-House · One Project Manager · One Warranty Across Trades

One Massachusetts Crew. Eight Trades. One Warranty.

Pro Build Home Services & Construction is a Massachusetts-licensed multi-trade contractor delivering construction, roofing, HVAC, plumbing, electrical, weatherization, outdoor, and specialty work since 2008. Same project manager from quote to commissioning. Same workmanship guarantee across every trade we touch.

Why Pro Build Exists

A Massachusetts homeowner shouldn't have to be the project manager.

Pro Build Home Services & Construction was founded in 2008 in Boston, Massachusetts on a single observation: every meaningful Massachusetts renovation is multi-trade, but the contracting industry isn't built that way. The kitchen remodel needs a panel upgrade. The bathroom triggers a gas line relocation. The new heat pump needs ductwork that touches the addition. Five trades, five contractors, five warranties, one homeowner playing project manager.

So we built the team that wasn't out there. Pro Build holds the Massachusetts CSL, the Mass Save HPC authorization, the EPA Section 608 Universal certification, the master plumbing license, and the master electrician license — every credential that matters, in-house. One quote. One timeline. One project manager. One warranty across every trade we touch.

Meet The Founder

Kevin Sullivan built this team.

Kevin Sullivan, Master Construction Supervisor & Mass Save Heat Pump Contractor, started Pro Build in 2008 after fifteen years in Massachusetts construction watching the same problem repeat: a competent GC subbing out the trades that mattered most — heat pump install, panel upgrade, lead-safe demolition — to one-truck operations the homeowner never met and couldn't hold accountable.

Today Kevin reviews every Pro Build estimate personally and sits in on the project kickoff for any project over $50,000. The Mass Save HPC authorization is in his name. The Master CSL is in his name. Every Pro Build crew member trains under his commissioning checklist before joining a job — covering code-compliant rough-in, refrigerant brazing standards, panel labeling, lead-safe containment, and final-walkthrough QA.

Massachusetts Construction Supervisor License
Unrestricted CSL — structures up to 35,000 cubic feet, structural alterations, gas appliance installation, mechanical systems
Mass Save Heat Pump Contractor (HPC)
Authorized to file every Mass Save heat pump rebate on the homeowner's behalf — at no extra cost to the project
EPA Section 608 Universal
Refrigerant certification covering R-410A, R-32, R-454B — every refrigerant in active service today
EPA RRP Lead-Safe
Required for any work disturbing painted surfaces in pre-1978 homes — most Boston housing stock falls under this rule

The Pro Build In-House Test

Five questions every Massachusetts homeowner should ask before hiring a GC.

Most Massachusetts general contractors will tell you they "handle everything." These five questions separate a real multi-trade contractor from one who'll sub out the work that matters most. Ask any GC quoting your project — including us.

  1. Who actually holds the trade license?A real multi-trade GC has the CSL, the master plumbing license, the master electrician license, the Mass Save HPC, and the EPA 608 — in their company's name. If a separate company shows up to install the heat pump or upgrade the panel, that's a sub. Pro Build holds every license in-house, every time.
  2. Are the crew members W-2 employees or 1099 subs?Subcontractors are 1099. They aren't your contractor's employees — they're independent vendors with their own liability policies and their own warranties. Pro Build crews are W-2 employees, working under our liability and our warranty. Same uniform, same truck, same chain of command.
  3. Is there one project manager — and is that person yours?A real multi-trade GC assigns one project manager who owns the timeline, the change orders, the inspection schedule, and the rebate paperwork. If you're calling the HVAC sub directly to ask when he's coming back, you're the project manager now. Pro Build assigns one Lead Construction Supervisor per project — yours from quote to commissioning.
  4. Is there one warranty across every trade?When the work is split across subs, every trade has a separate warranty. The roofer warranties the roof. The HVAC sub warranties the system. The GC warranties the framing. If something fails at the seam — a heat pump line set leak that damages new drywall, say — nobody owns it. Pro Build warranties every trade we ran for five years, in writing, signed by a Master CSL.
  5. Who files the Mass Save rebate paperwork?Mass Save heat pump rebates only flow through an authorized HPC partner. If your GC isn't an HPC, the rebate filing falls to whichever HVAC sub he hired — and the homeowner often loses thousands waiting for paperwork nobody owns. Pro Build files every Mass Save application directly. You sign the homeowner authorization. We do everything else.

Why we wrote this down.If a competing contractor passes all five questions, hire them with confidence. If they don't, you now know which seams are going to fail mid-project. Either way, you're a smarter buyer.

Massachusetts Credentials

Six licenses. One company.

Every credential Massachusetts law requires for the work we do — held in-house, never rented from a sub. Verifiable through the Massachusetts state registry on request.

Frequently Asked About Pro Build

The questions Massachusetts homeowners actually ask before hiring us.

Straight answers, no upsell. If your question isn't here, the free 5-minute quote form sends it directly to a Lead Construction Supervisor.

How long has Pro Build been in business in Massachusetts?
Pro Build Home Services & Construction has operated continuously in Massachusetts since 2008 — over 17 years of multi-trade contracting under the same Construction Supervisor License and the same founder. Our office is in Boston, MA, and we serve every major Massachusetts city and the entire Greater Boston metro area.

Do you really do all eight trades in-house, or do you sub the work out?
All eight trades in-house, with W-2 employees working under one Construction Supervisor License. We hold the master plumbing license, master electrician license, Mass Save HPC, EPA 608 Universal, and EPA RRP Lead-Safe — every credential each trade legally requires. The five-question In-House Test above is exactly how we measure ourselves and how we recommend you measure any contractor quoting your project.

Are you licensed and insured to work in Massachusetts?
Yes. We hold an active Massachusetts Construction Supervisor License, Home Improvement Contractor registration, $2 million general liability insurance, full workers' compensation as required by Massachusetts law, EPA RRP Lead-Safe certification for pre-1978 properties, EPA Section 608 refrigerant certification, and Mass Save Heat Pump Contractor authorization. Every license is verifiable through the Massachusetts state registry on request.

What's the difference between Pro Build and a typical general contractor?
Most Massachusetts general contractors hold the construction supervisor license and sub out everything else — HVAC, plumbing, electrical, insulation. The homeowner ends up coordinating four or five separate companies with four or five separate warranties. Pro Build holds every trade license in-house. Same project manager, same warranty, same accountability across every trade we touch. The whole architecture of the company is built around making "one quote, one timeline, one warranty" actually true.

We serve over 50 Massachusetts cities and towns including Boston (all 23 neighborhoods), Worcester, Cambridge, Newton, Brookline, Somerville, Quincy, Lynn, Lowell, Framingham, Plymouth, and the entire Greater Boston metro.
