Why Hire a state-licensed or NEHA Certified Mitigator?
EPA recommends that you have a qualified contractor fix your home because lowering high radon levels requires specific technical knowledge and special skills. Without the proper equipment or technical knowledge, you could actually increase your radon level or create other potential hazards. A mitigator licensed by NEHA or your state must undergo special training and adhere to higher standards.
How To Select A Contractor
Choose a contractor to fix a radon problem just as you would for other home repairs. Get more than one estimate and ask for references, and to contact some of those references to ask if they are satisfied with the contractors' work. Also, ask your county or state consumer protection office for information .
Use this check-list when evaluating and comparing contractors and ask the following questions:
| Yes |
No |
|
| |
|
Will the contractor provide references or photographs, as well as test results of 'before' and 'after' radon levels of past radon reduction work? |
| |
|
Can the contractor explain what the work will involve, how long it will take to complete, and exactly how the radon reduction system will work? |
| |
|
Does the contractor charge a fee for any diagnostic tests? Although many contractors give free estimates, they may charge for diagnostic tests -- these tests help determine what radon reduction system should be used, but are not always necessary |
| |
|
Did the contractor inspect your home's structure before giving you an estimate? |
| |
|
Did the contractor review the quality of your radon measurement results and determine if appropriate testing procedures were followed? |
-
Do the contractors' proposals and estimates include:
| Yes |
No |
|
| |
|
Proof of liability insurance, being bonded and licensed? |
| |
|
Proof of state and/or NEHA certification? |
| |
|
Installation of a warning device to caution you if the radon reduction system is not working correctly? |
| |
|
A guarantee to reduce radon levels to 4 pCi/L or below, and if so, for how long? |
| |
|
A description of materials to be used? |
Ok, I picked a mitigator, now what?
Expect a contract before any work starts. Carefully read the contract before you sign it.
The contract should include:
- The total cost of the job, including all taxes and permit fees; how much, if any, is required for a deposit; and when payment is due in full.
- The time needed to complete the work.
- An agreement by the mitigator to obtain necessary licenses and follow required building codes.
- A statement that the contractor carries liability insurance and is bonded and insured to protect you in case of injury to persons, or damage to property, while the work is done.
- A guarantee that the contractor will be responsible for damage and clean-up after the job.
- Details of warranties, guarantees, or other optional features, including the acceptable resulting radon level.
- A declaration stating whether any warranties or guarantees are transferable if you sell your home.
- A description of what the contractor expects the homeowner to do (e.g., make the work area accessible) before work begins.
