Homeowners in Greater Boston — Quincy, Braintree, Milton, Walpole, Hingham, Weymouth — ask us this question every week. And we get it: nobody wants to get a number they can't actually plan around. This guide breaks down what garage door replacement actually costs in 2026, with real numbers for the South Shore market.
What You'll Actually Pay in 2026
For a standard residential replacement in Greater Boston, you're looking at:
- Basic steel door, single-car: $900–$1,500 installed
- Insulated steel door, single-car: $1,200–$1,900 installed
- Insulated steel door, two-car: $1,600–$2,800 installed
- Carriage-house /Designer steel: $2,200–$4,200 installed
- Full-view aluminum/glass: $2,800–$6,000+ installed
These are total project costs — door plus installation. Our installation fee is a flat $189, which covers removal of your old door, haul-away, and a complete safety setup. No surprises.
What Actually Moves the Price
The cost isn't just about the door style. These four factors have the biggest impact on your final number:
1. Door Size
Standard sizes (8×7 single, 16×7 double) use stock or quick-ship doors. Custom openings — anything wider than 10 feet, taller than 8 feet, or irregularly shaped — require custom orders with a 2–4 week lead time and a $200–$600 premium. Measure your opening yourself or include it in your service call — we measure as part of every installation visit.
2. Insulation Level
For Greater Boston homeowners, insulation isn't optional — it's a New England requirement. Here's the breakdown:
| Insulation Type | R-Value | Best For | Cost Add vs. Non-Insulated |
|---|---|---|---|
| Single-layer (no foam) | R-0 | Detached, unconditioned | Base price |
| Polystyrene (2-layer) | R-6 to R-8 | Attached garage, moderate use | +$150–$250 |
| Polyurethane (3-layer) | R-12 to R-18 | Attached/heated garage, everyday use | +$250–$450 |
3. Labor and Site Conditions
Standard replacement on a well-maintained opening is straightforward. But some jobs add time:
- Rotted framing: If the structural members around your opening are water-damaged, we quote repair before we quote the door. This typically adds $150–$400.
- Angle-cut flagstone or old stone headers: Older homes in Quincy, Milton, and Hingham sometimes have masonry that requires a specialist — add $200–$500 to the framing portion.
- Heavy spring tension: Standard residential torsion springs store 200–400 ft-lbs of energy. On oversized or custom-weight doors, the springs are heavier and take more care — no extra cost, just something to be aware of.
4. Whether You're Keeping Your Opener
If your existing opener is less than 10 years old and the bracket/rail are in good shape, we can usually work around it. If it's older, we'll tell you. Budget $350–$700 for a new LiftMaster, Chamberlain, or Genie opener if you need one.
Why Boston-Area Costs Run Higher
You may have noticed that some national websites quote lower numbers — $500–$800 for a new door installed. Those prices exist, but they typically come from big-box retail doors with thin steel, no insulation, and franchise installers who sub out the work.
Greater Boston has three things that affect realistic replacement costs:
- Home age: Many South Shore homes were built in the 1960s–1980s. Their openings aren't always standard sizes, and their framing sometimes needs work before a new door can go in properly.
- Climate: Massachusetts sees 40–60 freeze-thaw cycles per winter. A door with poor weatherstripping or low-grade hardware won't hold up. We use Clopay doors specifically because their weather seals and hardware are rated for New England conditions.
- Labor market: Licensed garage door technicians in the Boston metro area earn more than the national average — which means $99 installation specials are almost always subsidized by inflated door pricing elsewhere in the quote.
How to Get a Number You Can Actually Use
The fastest path to a real quote: submit a service request or call us at (781) 222-DOOR. Tell us:
- Your rough opening size (width × height)
- Whether your garage is attached or detached
- Whether you want to keep your existing opener
- Any style preferences (raised panel, carriage-house, full-view)
We'll come out, measure, and give you a written estimate — no obligation. Most quotes are done the same day.
You can also get a ballpark using our service request and we'll provide pricing on Clopay styles, insulation levels, and sizes for your specific opening.
Our pricing philosophy: We don't pad estimates to leave room for negotiation. The number we give you is the number. If we find something unexpected on-site, we tell you before we proceed — not after the invoice.
