Questions to ask a garage door repair company before you hire

Updated November 10, 2026 · KeystoneProGuide editorial team

What should you ask a garage door company before you hire it?

Ask who they are, what the visit costs, what exactly has failed, what the price covers and how the door will be tested when the work is done. The twenty questions below are grouped by the moment to ask them. Each comes from advice published by a consumer agency, the Better Business Bureau, the federal opener standard or one of the cost publishers, and each has a short note on why it matters.

What should you ask on the phone?

What is the full name of your business, and where is it based? The Better Business Bureau says to listen to the name given on the phone, ask for the address, and compare both with the advertisement you found.
What is your Pennsylvania registration number? A home improvement contractor must put its number, PA followed by digits, on advertisements and estimates. The Pennsylvania rules guide shows how to look one up.
Is there a charge for coming out, and does it come off the bill if I go ahead? This Old House puts a diagnostic visit at $50 to $75 and says the fee is usually waived once the work is approved. HomeGuide lists the same question, so that a diagnostic fee does not come as a surprise.
Do you charge more in the evening or at the weekend? This Old House says after-hours work can sometimes double the bill. If the door is safe and closed, a weekday visit is cheaper.
Who will be coming, and how will I know them? Connecticut's consumer protection department, which investigated garage door repair complaints in 2025, heard from homeowners about workers with no identification and unmarked vehicles.

What should you ask once the door has been looked at?

Which part has failed, and why does it need replacing? It is the first question on the list This Old House gives for hiring. The Better Business Bureau says a qualified technician should be able to explain the problem and the solution clearly.
Will you put the price in writing before you start? The Bureau advises a written estimate covering the scope of work, the materials and the costs before any work begins. In Pennsylvania a home improvement contract for more than $500 has to be in writing in any case.
Is that a fixed price, or time and materials? Angi suggests asking whether a company charges hourly or by the task. If the answer is time and materials, the Pennsylvania Attorney General's office says the contractor must give a written cost estimate first, and the bill may not go more than 10% above it without a signed change order.
Are you replacing both springs, and what are the new ones rated for? DASMA, the door manufacturers' trade association, says both springs should be replaced even when only one has broken. This Old House says standard torsion springs are rated for about 10,000 cycles and upgraded ones for about 25,000, so the rating tells you what you are buying.
Do you have the parts with you? HomeGuide suggests asking whether replacement parts are carried on the service vehicle or whether more trips will be needed.
What happens to the old parts, and is there a charge? This Old House includes disposal fees among the costs that can appear on an invoice.

What should you ask about a new door or opener?

Will you measure the opening yourself before ordering? HomeGuide says a contractor must measure in person before giving a final estimate and ordering a door.
Does the price include taking away the old door or opener? Angi says removal of an old door can cost $50 to $200 where it is charged separately, and that you should ask whether it is in the quote. HomeGuide says some companies charge extra to remove an old opener.
Is the new door going on new track? DASMA says an old track may not fit a new door, and that the track designed for the door should be used.
Will the existing safety sensors be reused? HomeGuide notes that some opener estimates leave sensors out and that a new opener may not work with the old ones.
Does this job need a permit, and who applies for it? The Federal Trade Commission lists a contractor who asks you to get the building permits among the signs of a home improvement scam. Angi says to expect the installer to obtain a permit where one is needed.

What should you ask about the warranty?

What does the warranty cover, for how long, and who honors it? The Federal Trade Commission says a warranty must be available to read before you buy, and that anything it does not list should be assumed not to be covered. Ask separately about parts and labor, and whether a claim goes to the installer or the manufacturer. HomeGuide notes that springs rated for 10,000 cycles often carry a 3-year warranty, which is much shorter than the 10 years it says is standard on a door.
Is that promise in writing? The Commission's advice is to get any spoken promise, such as free repairs later, written down.

What should you ask before you pay?

Will you test the reverse and the sensors with me? HomeGuide's list includes asking whether safety features such as auto-reverse will be tested after the repair, and Angi says to test the remote, the sensors and any automatic closing feature before the technician leaves. The federal standard for openers also requires installation instructions that tell the installer to show the user how the manual release works.
How do you take payment, and will the invoice be itemized? The Connecticut department treats a request for cash or a payment app as a possible sign of a scam. The Better Business Bureau says reputable companies let you pay after the work is finished. Angi's advice is to keep the contract and the invoices, which you will need for any warranty claim.

What do the answers tell you?

No single answer settles it. A company that names itself consistently, quotes in writing, explains the failed part and tests the door in front of you has done what the consumer agencies ask for. A company that will not give an address, a price or a registration number has told you enough. How to choose a garage door repair company covers the checks behind these questions, and the guide to garage door repair scams describes what regulators have found when the answers were false.
