How to Hire a Garage Door Installer: Complete Vetting Guide
This guide is written for the homeowner, not the contractor. No sales pitch, no lead generation forms. Just a practical framework for finding someone who will do the job right at a fair price.
Where to Find Installers
Manufacturer dealer locators
Clopay, Amarr, and Wayne Dalton have dealer locator tools on their websites. These are authorised dealers who have completed manufacturer training and can offer full product warranties.
Neighbour referrals
The single best source. A neighbour who had a good experience with an installer can show you the finished work and tell you about the process. Ask about price, timeline, and cleanup.
Hardware store referrals
Home Depot and Lowe's partner with specific installation contractors. These contractors are pre-vetted but may cost 10% to 20% more because the store takes a cut.
Online review platforms
Google Business, Yelp, and BBB reviews. Focus on reviews that mention specific details about the work, not just generic praise. Look for patterns in complaints (delays, hidden charges, poor cleanup).
Contractor matching services
Angi, HomeAdvisor, and Thumbtack connect you with local installers. You will get multiple quotes quickly, but be prepared for follow-up calls and emails. These services charge the contractor a lead fee, which may be reflected in the price.
Licence and Insurance Requirements
These are non-negotiable. An unlicensed, uninsured contractor may be cheaper, but the risk to your home and wallet is not worth the savings.
Contractor Licence
Required in most states for garage door work. Verify the licence number through your state's contractor licensing board website. The number should appear on all paperwork.
How to verify: search "[your state] contractor licence lookup"
Liability Insurance
Minimum $1,000,000 in general liability coverage. This covers damage to your property during installation (dropped door on car, damaged drywall, scratched floor).
Ask for: Certificate of Insurance (COI)
Workers' Compensation
Covers injuries to the installer while working on your property. Without it, you could face a personal injury claim if a worker is hurt.
Required in most states for businesses with employees
15 Questions to Ask Every Installer
Print this list or save it on your phone. Ask each question and note the response. A contractor who answers all 15 confidently and specifically is worth paying a premium for.
How long have you been installing garage doors?
Look for 3+ years of dedicated garage door experience, not just general contracting.
Are you licensed and insured?
Ask for the licence number and verify it online. Confirm liability insurance ($1M minimum) and workers' comp.
Can I see your proof of insurance?
A legitimate contractor will have a certificate of insurance (COI) ready. If they hesitate, that is a red flag.
What brand of springs do you use?
Quality springs (Dasma-rated, oil-tempered) last 15,000 to 20,000 cycles. Cheap springs fail in 5,000 cycles.
What is your labour warranty?
1 year is the minimum. Good contractors offer 2 to 5 years. Get it in writing.
Who will actually do the installation?
Some companies send subcontractors or day labourers. You want to know who is doing the work and whether they are trained.
What is included in your quote?
Removal, disposal, hardware, weatherstripping, opener reconnection. Get every item in writing.
How do you handle unexpected issues?
Good answer: written change order with your approval before any additional work. Bad answer: 'we will figure it out.'
What is your typical timeline?
A standard replacement should be scheduled within 1 to 2 weeks and completed in one day.
Do you pull permits when required?
For new openings and structural work, permits are legally required. Skipping permits creates liability for you.
What is your payment schedule?
10% to 20% deposit, balance on completion is standard. Never pay in full upfront.
Will you clean up the work area?
Professional installers remove all debris, packaging, and the old door. Get this confirmed in writing.
Do you have references I can contact?
A contractor who cannot provide 3 recent references may not have enough satisfied customers.
What happens if the door is damaged during installation?
The contractor's insurance should cover damage. Get their answer in writing.
Do you offer maintenance packages?
Annual maintenance ($75 to $150) extends door life significantly. Not required, but worth asking about.
Red Flags
Any one of these should make you pause. Two or more should send you to the next contractor on your list.
Door-to-door sales
Legitimate garage door companies do not send salespeople to knock on your door. This is almost always a high-pressure sales tactic with inflated prices.
'Today only' pricing
A real price does not expire at midnight. This tactic prevents you from getting competing quotes, which is exactly why they use it.
No written quote
A verbal price has zero legal standing. If they will not put it in writing, do not hire them.
No licence number on materials
In licensed states, the number should be on the quote, invoice, business card, and truck. Missing means potentially unlicensed.
Full payment upfront
10% to 20% deposit is normal. Full payment before work starts removes your leverage if something goes wrong.
No physical business address
A contractor operating only from a cell phone and a truck is harder to hold accountable if problems arise.
Cash only, no receipt
This usually means they are not reporting income and may not be carrying insurance. You also lose your payment record.
Refuses to show insurance
If a worker is injured on your property and the contractor has no workers' comp, you may be liable. Never hire an uninsured contractor.
National Chains vs Local Companies
Neither is universally better. Your best choice depends on what you value most.
| Factor | National Chain | Local Company |
|---|---|---|
| Price | 15% to 25% higher | 15% to 25% lower |
| Warranty | Strong, backed by corporate | Varies, depends on the company |
| Response time | Usually 1 to 3 days | Often next-day or same-week |
| Quality consistency | Standardised training, uniform quality | Varies widely, check reviews |
| Flexibility | Rigid pricing, limited negotiation | More willing to negotiate and customise |
| Brand selection | May push their own brands | Usually offer multiple brands |
| Emergency service | 24/7 availability common | Often limited hours |
Major national chains include Precision Door Service, Overhead Door Corporation, and A1 Garage Door Service.
