How to Choose a Mold Remediation Company in Pennsylvania
Getting quotes for mold work and not sure who to trust? Pennsylvania doesn't license mold companies, so nobody has checked the one quoting you. Our local mold specialist comes out, looks at the job and puts the price in writing.
Why Pennsylvania Doesn't License Mold Companies
Pennsylvania has no mold license, no required mold certification and no state mold standard, which the Department of Health confirms on its own fact sheet. A company can start quoting mold work tomorrow without proving it knows how the job should be done.
Mold removal isn't licensed in Pennsylvania the way asbestos removal is, so the checking falls to you rather than to a state inspector.
What the Law Does Require of a Mold Contractor
The Home Improvement Consumer Protection Act covers contractors doing $5,000 or more of residential work a year. Mold remediation isn't named in the act, but a company removing mold from your house is doing residential work on it, which is what the act covers. Those contractors register with the Attorney General, renew every two years, and carry at least $50,000 of personal injury coverage and $50,000 of property damage coverage.
The registration number has to appear on every contract, estimate, proposal and advertisement the company puts out in Pennsylvania. If there's no number on your quote, ask why before you go any further.
You can check any number yourself on the Attorney General's contractor search, or by calling 1-888-520-6680. The Attorney General states on the same page that registration is not an endorsement, so a number tells you the company has filed paperwork and paid a fee, and nothing about the standard of its work.
Six Questions to Ask a Mold Company Before You Hire
Ask any mold company these six questions and you'll soon know how they work. That goes for our local mold specialist too, so ring round, ask the same things and see how the answers compare.
Where's the water coming from, and is fixing it in the price?
Mold is the symptom. If nobody mentions the leak, the drainage or the humidity, you'll be paying for the same wall again next year.
What's coming out, and what's staying?
A quote should name the materials being removed, the ones being cleaned in place and anything left alone. Vague scope, vague job.
How will you keep it out of the rest of the house?
Ask about sheeting, doorways and air filtration. Cutting into moldy drywall without sealing the room spreads spores everywhere.
Is testing afterwards part of the price?
Some include a final check, some charge for it, some skip it. Any of those is fine as long as you know which before you sign.
Are you IICRC certified?
The IICRC writes the S520 standard that proper mold work follows. Pennsylvania doesn't license mold companies, so this is the closest thing to a qualification.
What's your Pennsylvania contractor registration number?
Anyone doing more than $5,000 of home improvement work a year has to register with the Attorney General. It takes a minute to check.

What Has to Be in a Mold Remediation Contract
Any residential job over $500 needs a written contract, and the law lists what belongs in it.
The registration number
Every contract, estimate, proposal and advertisement a Pennsylvania contractor puts out has to carry it, so a quote without one is the first thing to question.
The price and the work
The total price, a description of what's being done, and the approximate start and finish dates all belong in writing before anyone begins.
The deposit
The deposit goes in as its own figure, and any special-order materials are listed separately from the rest of the price.
The Attorney General's number
The toll-free line for the Bureau of Consumer Protection has to be printed in the contract so you can check the company yourself.
Your right to cancel
The contract has to tell you that you can cancel within three business days of signing, without penalty.
The act sets two limits on what a contractor can ask you to pay before the work starts. A contractor cannot take any payment at all before the contract is signed, and on jobs over $5,000 the deposit is capped at a third of the price plus the cost of any special-order materials. Mold jobs generally run between $1,500 and $6,000, so on a $4,000 job the deposit shouldn't be more than about $1,300, and the cost guide breaks the ranges down room by room.
If the contract is missing something the law requires, it isn't enforceable against you. A contractor who can't enforce the contract can't hold you to the price or the payment schedule if the work turns out badly.
Your Three Days to Cancel a Mold Contract
You can cancel a home improvement contract within three business days of signing, without penalty and without giving a reason. Contractors used to argue that the cancellation had to be in writing, and in April 2026 the Pennsylvania Supreme Court ruled on that argument. The court held that no writing is needed, and what matters is whether the contractor received actual notice inside the three days, so telling them clearly on the phone counts.
Send an email as well, because a dated message removes any argument about when you canceled.

Certifications Worth Asking a Mold Company About
The IICRC writes the S520 standard that mold remediation should follow, and the 2024 edition is the current one. Pennsylvania doesn't require it, so a company that holds S520 certification went and got it when nothing made them.
The second certification isn't optional at all. If the house was built before 1978 and the work will disturb painted surfaces, the firm has to be EPA Lead-Safe certified under a federal rule, whatever Pennsylvania does or doesn't require. Around 48% of houses in Gettysburg borough were built before 1940, so the rule reaches a good share of the work done in the county, and mold in old Gettysburg homes covers what else changes in a house that age.
Before the work starts
Ask for both
A company that holds IICRC certification and EPA Lead-Safe certification will have the paperwork for each and can send you both.
What to Do If a Mold Job Goes Wrong
Complaints about home improvement work go to the Attorney General's Bureau of Consumer Protection on 1-800-441-2555. Contractors working without registration face civil penalties of $1,000 or more.
Keep everything in writing from the start: the contract, the change orders, the invoices and the dates. A complaint backed by paperwork gives the Bureau something to act on, where one based on a conversation at the door gives them nothing to check.
Hiring a Mold Company Questions
Does a mold remediation company need a license in Pennsylvania?
No mold license exists in Pennsylvania, so no company can hold one. What they do need, if they do $5,000 or more of residential work a year, is registration with the Attorney General, and you can check that yourself on the contractor search.
Can I cancel a mold remediation contract after signing it?
You have three business days from signing, with no penalty and no reason needed. Since the Pennsylvania Supreme Court's 2026 decision, canceling by phone counts as long as the contractor clearly receives the message inside those three days.
How much deposit can a mold company ask for?
Nothing at all before the contract is signed. After signing, on a job over $5,000, the deposit is capped at a third of the price plus the cost of any special-order materials.
