Our radon mitigation guarantee for York, PA homes is simple: if your clearance test after installation does not come in below 4.0 pCi/L, we keep working at no charge until it does. Every system is installed by DEP-Certified Installers and built to Pennsylvania's mitigation standards.
This page explains what the guarantee covers, how our certification works, and how to check any contractor before you hire them. It is the trust page behind our York radon mitigation service, so you can see exactly what you are getting in writing.
PA DEP certification: number provided on every written quote
What our clearance guarantee includes
The guarantee is written into your quote before any work starts. Here is what it covers:
- A clear target. The clearance test must come in below 4.0 pCi/L, the EPA action level.
- More work at no charge. If the first result is not below 4.0 pCi/L, we come back and fix it. That can mean added sealing, a second suction point or a stronger fan.
- A retest at no charge. After any added work, the home is tested again so you have a result on paper.
- Written proof. You get the test result, a description of the system and the label details for your records or a home sale file.
The guarantee does not depend on a specific number of visits. We keep going until the clearance target is met. Our full radon mitigation system installation process is designed to hit that target on the first try, so return trips are the exception.
When the guarantee applies
The guarantee applies to every new active system we install in York and the surrounding York County area. It covers the clearance test that follows installation.
It also helps to know what it does not cover. Radon levels in any home can rise and fall over time. Big changes to the house, like finishing a basement, adding an addition or cutting new holes in the slab, can affect how a system performs. The EPA and PA DEP both recommend retesting at least every two years and after major renovations.
If an older system someone else installed is not keeping up, we can help with that too. Our radon fan replacement and system repair service covers any brand of system.
How the guarantee works, step by step
- Written quote. We inspect the foundation and give you a written price that includes the guarantee terms.
- Install. Most homes are done in one day. The system includes a fan, sealed piping, a gauge and a permanent label.
- Clearance test. The test starts no sooner than 24 hours after the system is running and within 30 days, following EPA guidance.
- Result below 4.0 pCi/L. You get the written result and system paperwork. The job is complete.
- Result at or above 4.0 pCi/L. We diagnose why, make the fix at no charge, and retest until the result is below 4.0 pCi/L.
Why PA DEP certification matters
Pennsylvania is one of a small number of states with its own radon certification law. Under the Radon Certification Act and 25 Pa. Code Chapter 240, anyone who tests, mitigates or runs a lab for radon on someone else's property must be certified by the PA Department of Environmental Protection. Homeowners testing their own homes are exempt.
To earn mitigation certification, an individual must complete a DEP-approved radon mitigation course, pass a DEP-approved written exam, and have relevant experience. The state's regulations set certification to last two years, after which it must be renewed. Certified firms must also make sure their people get continuing education every two years.
Here is how the main credentials compare:
| Credential | Who issues it | Required to work in PA? |
|---|---|---|
| PA DEP radon mitigation certification | PA Department of Environmental Protection | Yes, for anyone mitigating for others |
| PA DEP radon testing certification | PA Department of Environmental Protection | Yes, for anyone testing for others |
| NRPP certification | National Radon Proficiency Program (private) | No, not on its own |
You can look up any certified tester or mitigator in the DEP's radon services directory, which you can reach from the PA DEP Radon Division page.
What the guarantee means for your price
A guarantee only means something if it is in writing and the price does not jump after the fact. Our quotes list the system, the sealing work and the guarantee terms together. Our standard system is priced at $935 to $1,320.
Pennsylvania cost guides commonly cite roughly $800 to $2,500 for a standard system. Where your home lands depends on the foundation, the number of suction points and the pipe route. For a full breakdown, see our guide to radon mitigation cost in York.
Why this matters in York
York County is in EPA Radon Zone 1, the highest-potential group of counties on the EPA radon zone map. Many York homes have stone, block or mixed foundations that leak more soil gas than a newer poured slab. That makes a well-built system, and a guarantee that covers the hard cases, more important here than in many other places.
Seasons matter too. In winter, houses are closed up and warm air rising inside tends to pull more soil gas in. A system that clears in summer still needs to keep working in January. That is one reason we size fans and suction points for the house, not the minimum.
Why choose us
State certification you can check
Pennsylvania law requires PA DEP certification to mitigate radon for others, and that certification only comes after a DEP-approved course, a DEP-approved exam and documented experience. Our installers are certified, and our number is printed on every quote and on the label fixed to every system. You do not have to take our word for it. Look us up in the DEP radon services directory before you book, and compare us with anyone else you are considering.
A guarantee written into the quote
Many contractors promise to "get it down." Ours is written into the quote, with a clear number: below 4.0 pCi/L on the clearance test. If we miss it, we keep working at no charge until we hit it. That covers extra sealing, added suction points and fan changes. Because the terms are written before you sign, you know exactly what happens if the first round of work is not enough, and there is no surprise invoice for the fix.
Systems built to 25 Pa. Code 240.308
Pennsylvania sets specific rules for radon systems in homes three stories or less. The exhaust must point straight up and end at least 10 feet above the ground and 10 feet from operable windows and doors. The fan cannot sit in a basement, crawl space or living space. Floor-wall cracks and openings must be sealed, and the system must carry a permanent label. Every system we build follows those rules and includes a gauge you can check at a glance.
Frequently Asked Questions
How do I verify a radon contractor is DEP-certified?
Search the PA DEP radon services directory by the person's name or certification number. Red flags include a missing number on the quote, a number that does not match the name, or a crew that cannot show proof of certification. Here is how to choose a radon contractor in PA.
Is NRPP certification enough in Pennsylvania?
No. NRPP is a national private credential, but Pennsylvania requires its own PA DEP certification for anyone who tests or mitigates radon for others. A contractor can hold both, but DEP certification is the one the law requires here. Read more on NRPP vs. PA DEP radon certification.
What happens if my radon is still high after mitigation?
Under our guarantee, we diagnose the cause, then add sealing, another suction point or a stronger fan at no charge. We retest after each fix until the result is below 4.0 pCi/L. For the common causes and fixes, see radon still high after mitigation.
How long is the warranty on the fan and the system?
There are usually two warranties. The fan maker covers the fan itself for a set period, often around five years. The installer covers workmanship and, with us, the clearance result. Ask for both in writing. Learn more in radon system warranties explained.
What standards does a PA radon system have to meet?
25 Pa. Code Chapter 240 sets the rules. The exhaust must vent straight up, at least 10 feet above ground and 10 feet from operable windows. The fan cannot sit in living space or a basement, and the system needs a permanent label. See Pennsylvania radon mitigation standards.
When is the clearance test done?
The clearance test starts after the system has run at least 24 hours and within about 30 days of installation, following EPA guidance. Closed-house conditions apply during the test. Most short-term tests run at least 48 hours. Get the details on retesting after radon mitigation.
