Are there advantages to using a contractor to do ENERGY STAR Home Sealing for me? Follow

Yes. A contractor will have advanced testing tools and products to help them find hidden leaks and seal them up quickly. Even if you are a do-it-yourselfer, in some cases you may need to call in a contractor for certain parts of the job (e.g., if you have old electrical wiring, roof damage, attic ventilation issues, or if you need to address recessed can lights in the attic floor). A professional can also perform a combustion safety test after air sealing to make sure your furnace, boiler, or water heater are venting properly after sealing.
