How to Vet a Siding Contractor Before You Sign Anything
September 13, 2026 | Home Improvement | No Comments
New siding is a big cheque. For a lot of people, the biggest home cheque outside the mortgage. And you are not really buying boards. You are buying the company that installs them. Choose well and the project hums along and holds up for decades. Choose badly and you spend years paying for somebody else’s shortcuts. A bit of homework up front prevents most of that pain.
Start With the Paper Trail
Begin with paperwork. Any serious exterior company in BC should produce three things without being asked twice. Proof of liability insurance. A WorkSafeBC clearance number. A written contract that nails down scope, materials, and timeline. If a simple request turns into excuses, move on. The good companies expect these questions. Some even seem pleased you asked. It signals you will be a careful client, and careful clients are the kind good companies want.
Ask Who Does the Work
Then find out who is actually swinging the hammers. Plenty of companies sell you the job, then hand it to whichever sub is free that week. Others keep trained crews on payroll, so the people who made the promises are the same people on your ladder. Comparing quotes around here, homeowners tend to notice that Mi Casa Exteriors in Port Coquitlam runs its own installation crews instead of subbing things out. One company from first quote to final walkthrough. Accountability stays simple that way.
About that clearance number, because this one catches people off guard. Insurance protects your property if something breaks. WorkSafeBC protects your wallet in a way most owners have never heard of. Hire a contractor who is not registered or has not paid their premiums, and you can be left holding the bill for what they owe. WorkSafeBC’s guidance for homeowners spells this out and says to get a clearance letter before work starts. The letter is free. Takes a few minutes online. Cheap protection for a project this size.
Watch How the Money Flows
Watch the money next. Be wary of anyone wanting a fat deposit before a single board comes off the wall. The most confident companies flip that risk toward themselves. Some now start at zero deposit and only take final payment once you are happy with the finished job. How a company structures payment tells you plenty about how it expects the job to go.
Read the Warranty Twice
Read the warranty twice, slowly. A one-year labour warranty is close to worthless on an exterior meant to last 30 years or more. Get the workmanship coverage in writing and note whose signature is on it. A warranty signed by the company and the installer together beats a vague line in a brochure. And read the exclusions as carefully as the coverage. Ten minutes in the fine print now beats a dispute later.
Finally, trust the small stuff. Did they show up when they said? Did the quote land on time, in detail? Did your follow-up questions get straight answers? Companies do not get more careful after you sign. Whatever you see during the sales process is the best version you will ever get. Believe it.
