"General contractor" gets used loosely — some homeowners mean a roofer, some mean whoever's coordinating a full renovation, and some just mean "someone who can handle more than one thing." We get asked about it enough, in enough different contexts, that it's worth actually explaining: what a general contractor does, when you need one instead of a single-trade specialist, and how to tell a real one from someone who's just subcontracting everything and marking it up.
What a General Contractor Actually Does
A general contractor manages a project end to end instead of you managing it. That means:
- One point of contact — you're not calling four different companies to coordinate a roof, siding, and gutter job that all touch the same part of the house
- Sequencing the work — knowing that gutters go on after siding, not before, and that a roof leak needs to be fixed before interior drywall work starts, not after
- One set of licensing and insurance covering the whole job — not four separate certificates you have to verify and track
- Accountability — if something's wrong, there's no finger-pointing between three companies about whose work caused it
The trade-off is real too: a true single-trade specialist who does nothing but roofing, all day, may go deeper on that one thing than a generalist. For a straightforward single-system job, that's a legitimate reason to hire a specialist directly. The question is whether your project is actually that simple.
When You Actually Need a General Contractor
Storm or Damage Hit More Than One System
Wind and water damage rarely respect trade boundaries — a bad storm that damages your roof often takes gutters or siding with it. Hiring a roofer and a separate siding company to fix related damage on the same house means two companies making assumptions about where the other one's work starts and ends.
You're Touching Multiple Systems in One Project
New roof plus new siding plus gutters, or an exterior refresh that spans several trades — this is exactly where a general contractor earns their fee. Scheduling, sequencing, and matching materials and colors across systems is a full-time coordination job on its own.
You Want One Warranty Conversation, Not Four
When something needs a warranty call five years later, it's a lot easier to make one call to the company that did the whole job than to figure out which of four separate contractors is responsible for the specific spot that's failing.
Full-Service Contractor vs. Specialist: The Real Difference
| Single-Trade Specialist | Full-Service General Contractor | |
|---|---|---|
| Best for | One isolated job (e.g. gutter cleaning, a small roof repair) | Multi-system projects, storm damage, full exteriors |
| Coordination | You manage scheduling between companies | Handled for you |
| Accountability | Split across each company | One company, one standard |
| Pricing | Separate quotes, separate line items | One scope, one estimate |
Neither is universally "better" — it depends on the job. A small, contained repair rarely needs a general contractor. A project that touches more than one system, or where damage isn't fully diagnosed yet, almost always benefits from one company owning the whole thing.
How to Vet a General Contractor in Massachusetts
- Check for a Construction Supervisor License (CSL) and Home Improvement Contractor (HIC) registration — both are required in Massachusetts for most residential work, and both are publicly searchable through the state's licensing lookup
- Ask who's actually doing the work — an in-house crew and a company that subcontracts everything to the lowest bidder are very different experiences, even if both call themselves a "general contractor"
- Get a written scope of work, not just a price — a real estimate spells out materials, sequencing, and what's included
- Ask for proof of insurance — general liability and workers' compensation, specifically, before anyone sets foot on your property
- Read reviews for how they handle problems, not just the 5-star ones — every contractor has an occasional issue; what matters is how they responded
The honest answer to "do I need a general contractor or just a specialist" is usually: if you can describe your project in one sentence about one system, call a specialist. If your sentence has "and" in it more than once, call a general contractor.
How Greg's Construction Approaches It
We're structured around four divisions — Roofing & Exterior, Gutters & Drainage, Renovations & Carpentry, and Junk Removal & Demo — under one company, one crew standard, and one point of contact. That's the actual mechanism behind "full-service": it's not marketing language, it's that the same company that replaces your roof can also handle the gutters that go with it and the cleanup after, without you coordinating between separate businesses. We're licensed and insured across all of it, and Greg still answers the phone directly.
