Trusted Attic Insulation Services in Wilmington, OH

If you have noticed that your home struggles to stay warm in winter or cool in summer even with a modern heating and cooling system in place. For residents in Wilmington, OH, the culprit is frequently the attic — a space that is consistently overlooked despite its enormous impact on energy performance. Our team at Thervex Insulation Co delivers professional insulation installation and upgrades with the depth of knowledge that only a specialist can provide.

No two attics are exactly alike, so our technicians never simply arrive and start installing without understanding what the space actually needs. Our team documents current insulation depth, locates bypass areas, evaluates airflow, and determines the thermal improvement required to bring your home up to current energy efficiency standards before recommending any specific solution. This diagnostic-first approach is what separates Thervex from contractors who simply blow in material without evaluating what is actually needed.

Once we have a complete picture of your attic's current condition, we recommend the most appropriate insulation type for your specific situation. Blown-in fiberglass or cellulose delivers maximum coverage in irregular spaces and around obstructions. Spray foam excels in hard-to-reach areas where air sealing is the primary goal. Batt insulation remains the right choice for straightforward open joist bays that are easily accessible. Residents of Wilmington, OH who schedule an assessment consistently experience significant reductions in heating and cooling costs within the first full season.

Air sealing is performed before insulation on every Thervex project because it is foundational to achieving maximum thermal performance. Drafts, bypasses around plumbing penetrations, gaps at electrical junction boxes, and open soffits can negate much of the benefit of new insulation if not addressed first. Our technicians seal these bypasses completely before any insulation material is placed so that the thermal envelope of your home is as complete as possible from the very first day after installation. The pairing of quality air sealing with correctly installed insulation is what produces the dramatic energy savings that Wilmington, OH homeowners experience after a Thervex project.

The company was built by founder Preston Galvez a credentialed professional who spent years conducting energy audits for a utility-sponsored weatherization program. Preston's career gave him a granular understanding of how attic insulation deficiencies drive energy waste and comfort problems in American homes. He launched Thervex specifically because he saw how hard it was for homeowners to find contractors who executed insulation work correctly. He holds Building Performance Institute certifications and personally mentors each new technician on proper installation techniques and air sealing best practices.
