How to Check Out a Contractor in Pennsylvania Before You Sign

We are a contractor telling you how to vet contractors, so read this with that in mind. It is also the article we would want a member of our own family to read, and every check on it takes minutes.

1. Get the registration number and verify it yourself

Most home improvement contractors working in Pennsylvania are required to register with the state, and registered contractors are issued a number beginning PA. It is meant to appear on their contracts, estimates and advertising.

Ask for the number, then look it up in the Attorney General's registry rather than taking the number on the paperwork as proof. Two minutes.

Ours is PA201169.

Worth being clear about what this is: registration is not a skill licence and it does not mean the state has inspected anyone's work. It means they are on the record, reachable, and carrying the insurance the registration requires. An unregistered contractor is the signal, and not because the paperwork is magic, but because someone unwilling to be on the record is telling you something.

2. Ask for the certificate of insurance, not a yes

Everybody says they are insured. What you want is the certificate, with dates on it that have not passed.

The reason this matters is unglamorous: if someone is hurt on your property working for an uninsured contractor, or a burst line floods the floor below, the question of who pays can land on your homeowner's policy. Ask who the carrier is and ask to see the certificate. Ours is through USLI.

3. Read the estimate for what is missing

This is where most of the useful information is. Cheap quotes are usually not cheaper work. They are less of it, and the rest arrives later as change orders. A quote that is genuinely itemized is easy to compare; a single number on a page is not.

Look specifically for whether these are in or out:

• Permits and inspection fees, and who pulls them.
• Demolition and disposal. Dumpsters and haul-away are real money.
• Substrate repair. Subfloor, framing, drywall behind what is coming off.
• Electrical the job actually requires. A modern kitchen needs dedicated circuits and GFCI protection at the counters; that is not optional and it is often not quoted.
• Which fixtures and materials are allowances rather than chosen. An allowance is a placeholder number, and a low one makes the total look better while guaranteeing the conversation later.
• Paint and trim after the work. Frequently left off.

Then put two quotes side by side line for line. If one is genuinely higher for the same scope, ask why. A contractor who can explain their own number will; that answer tells you plenty either way.

4. Ask what happens when they find something

Older Lehigh Valley houses hide things: knob and tube, a panel that cannot carry a modern kitchen, cast iron drains, a subfloor that has been quietly wet for years. The question is not whether something turns up. It is what happens the day it does.

The answer you want: work stops, they show you, you get a written change order with a price before anything continues. The answer you do not want is a shrug, or a surprise line on the final invoice.

5. Know how deposits are supposed to work

Pennsylvania limits how much a contractor can collect before work begins, and legitimate contractors know that and follow it. Ask what the deposit is, what it covers, and what the payment schedule is tied to.

The pattern to expect: a deposit that holds a place on the schedule and covers materials ordered for your job, then payments tied to progress, not a large sum up front and not the whole thing before anyone has started. If someone wants most of it in cash before demo, that is your answer.

6. Ask for the schedule in writing before demo day

Not "about three weeks." A written sequence: what happens in which week, which days the water and gas are off, and which room is out of use when.

A contractor who has planned your job can produce this. One who cannot has not planned it yet, and that is worth knowing before your kitchen is in a skip.

What none of this tells you

None of it tells you whether the work will be good. That comes from seeing what they have actually built, talking to people whose houses they built it in, and how straight they are with you during the estimate, including whether they will tell you something is a bad idea.

Read all of it with the same eye you would use on us. We would rather answer these questions than have you not ask them.
