How To Select A Contractor
Choose a contractor to fix a radon problem just as you would choose someone to do other home repairs. It is wise to get more than one estimate, to ask for references, and to contact some of those references to ask if they are satisfied with the contractors' work.
Use this checklist when evaluating and comparing contractors. All these areas should be a yes:
Will the contractor provide references or photographs, as well as test results of before and after radon levels of past radon reduction work?
Central Kentucky Home Inspections Inc. will provide references and photographs of our past radon mitigation jobs, We have been installing radon systems since 1986 and have not had one mitigation job that did not lower the radon levels to below the EPA’s action level.
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?
CKHI will explain the work that will be involved in installing the radon mitigation system and how long it will take to complete it. Most mitigation jobs can be installed in one day and the jobsite is kept clean during and after the work. If the radon system is installed on the outside of the home we try to put the system out if sight and paint the piping outside. We do let you know how the mitigation system will work to lower the radon levels in your home.
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 type of radon reduction system should be used and in some cases are necessary, especially if the contractor is unfamiliar with the type of home structure or the anticipated degree of difficulty. See "Radon Reduction Techniques" for more on diagnostic tests.
If diagnostic is needed we will have to charge for it, but most homes we mitigate we don’t have to do diagnostic testing. David McLean has a builder’s background with a firm knowledge of how homes are built old and new. We do give free estimates for homes in our area but we do have a small charge to travel to areas outside our normal service area, this fee is taken off the mitigation price.
Did the contractor inspect your home's structure before giving you an estimate?
CKHI will not give a radon mitigation estimate without looking at the home, there are so many factors that are different in each home and needs to be taken into consideration when designing a radon system.
Did the contractor review the quality of your radon measurement results and determine if appropriate testing procedures were followed?
Central Kentucky Home Inspections likes to see the past radon test results and may advise the owners to take more radon measurements before installing a radon mitigation system. Real-estate radon testing is different; This test should be performed by a certified radon testing professional and be conducted in an EPA approved location under EPA approved conditions. Most real-estate driven radon test only use one test to determine if radon mitigation work is needed.
Compare the contractors' proposed costs and consider what you will get for your money, taking into account: a less expensive system may cost more to operate and maintain; a less expensive system may have less aesthetic appeal; a more expensive system may be best for your home; and, the quality of the building material will affect how long the system lasts.
Does the contractor's proposal and estimate include:
Proof of state certification, professional proficiency or certification credentials?
David McLean is appropriately certified in Radon testing and Radon Mitigation by HEHA National Radon Proficiency Program, the leading certification program for radon professionals in North America, recognize by the EPA. Visit NEHA web. Sight at radongas.org to make sure radon testers and mitigations are certified.
Proof of liability insurance and being bonded, and having all necessary licenses to satisfy local requirements?
Central Kentucky Home Inspections Inc. carries liability insurance, workman’s comp. and is a Licensed Lexington, Kentucky contractor. We are a BBB member with an A+ rating.
Installation of a warning device to caution you if the radon reduction system is not working correctly?
Suction monitors are installed on our radon mitigation system, this give a visual indication the radon system is working. The EPA does suggest the homes with active radon systems are tested for radon every two years.
Testing after installation to make sure the radon reduction system works well?
CKHA test the radon levels in the home after the radon system is installed and does not ask for any payment on guaranteed jobs until the radon level in the home is below the EPA action level.
A guarantee to reduce radon levels to 4 pCi/L or below. And if so, for how long?
Most homes we can offer a Five-Year guarantee. There are some homes we cannot offer guarantees due to the type and age of the home. The radon levels will be lowered to below the EPA’s action level in most of the homes we do not guarantee.
We do not want to build into a guaranteed radon mitigation proposal added charges for work that may not be needed in older or complex homes. When we give a Five-Year guarantee we stand behind it and do not require that we test the home for an added fee each year.
