Sliding door repair is a small, fragmented industry, quality and honesty vary a lot between companies. These seven questions filter out the ones likely to upsell you or leave you with a weak warranty.
1. "Do you specialize in repair, or mainly sell replacements?"
Companies that primarily sell new doors have less incentive to recommend a $200 repair over a $2,500 replacement. A repair specialist's business model depends on fixing what's actually broken.
2. "Is the estimate free, even if I don't move forward?"
A genuinely confident company doesn't need to charge you just to find out what's wrong. If there's a trip fee regardless of outcome, that's worth knowing upfront.
3. "Is the warranty in writing, and what exactly does it cover?"
Ask for the specifics: how many months, parts and labor or just parts, and whether there's a fee to schedule a warranty visit. Vague answers here are a red flag.
4. "Can you show proof of licensing and insurance?"
A legitimate contractor should have both readily available and be comfortable providing them before work starts, not defensive about the question.
5. "What specific hardware will you install?"
"New rollers" can mean $8 plastic wheels or $40 stainless heavy-duty rollers. The price difference is usually justified by how long the hardware actually lasts, especially near the coast.
6. "Will I get an itemized invoice?"
An itemized breakdown of parts and labor protects you if something needs warranty service later, and it's a basic sign of a transparent business.
7. "What happens if you can't fix it?"
The best answer is simple: you don't pay, and they tell you honestly if replacement is genuinely the better option instead of forcing a repair that won't hold.
