Build a shortlist the smart way
Start with a handful of candidates from sources that filter for quality.
- Ask neighbors and local community groups for recent, first-hand referrals.
- Check manufacturer websites for authorized or certified local dealers.
- Read reviews across multiple platforms and look for patterns, not one-off complaints.
- Confirm each company has been in business locally for several years — warranty support depends on them still existing.
Aim for at least three companies to quote so you have a real basis for comparison.
Verify credentials before they visit
Screen out the risky operators before you spend time on quotes.
- License: confirm state or local licensing where required.
- Insurance: ask for proof of liability insurance and workers’ compensation — without it, an on-site injury can become your problem.
- Bonding: a bond protects you if the job is abandoned or botched.
- Physical address and real reviews, not just a phone number.
A legitimate contractor will provide this readily; hesitation is a red flag.
Get itemized, comparable quotes
Insist on written, line-item quotes so you compare apples to apples.
- Door make, model, material, and insulation level
- Opener make and model
- New springs, rollers, cables, and hardware
- Removal and haul-away of the old door
- Permit fees if required
- Labor and the labor warranty term
A vague lump sum hides substitutions. If one quote is dramatically cheaper, find out what was left out.
Questions to ask every candidate
Use the same questions with each company to reveal real differences.
- Who performs the work — employees or subcontractors?
- How long is the labor warranty, and who honors it?
- Do you pull the permit, or do I?
- What springs do you install, and what is their cycle rating?
- Do you balance the door and test the safety reverse before leaving?
- What is your policy if something fails a week later?
Clear, confident answers signal a company that has done this well many times.
Red flags and closing the deal
Watch for warning signs, then protect yourself in the paperwork.
- Red flags: large cash-only deposits, no written contract, pressure to decide today, no proof of insurance, or a quote far below all others.
- Green flags: itemized contract, clear warranty, permit handled, references offered freely.
Before signing, get the start date, payment schedule, and warranty in writing. Pay a reasonable deposit — not the full amount — and hold the final payment until the door is installed, balanced, and the safety features are tested in front of you.
