Thermline is not an insulation contractor

Thermline helps homeowners learn about insulation options and request introductions to local installers through our free matching service. We are not an insulation contractor, general contractor, energy auditor, or licensed home-performance company.

That means we do not perform installation work, inspect your house, diagnose building problems, pull permits, supervise job sites, or guarantee the work of any installer you may contact through our service.

The information on this site is general homeowner education. It is meant to help you ask better questions and compare options. It is not a substitute for an on-site evaluation by a qualified professional who can see your home, measure the space, and review local code requirements.

Costs on this site are estimates, not quotes

Any pricing information on Thermline is provided as a typical range or estimate, not a quote, bid, contract price, or guarantee. Real project cost can vary a lot from one home to another.

Your actual price may depend on:
- the area being insulated
- the insulation material used
- the R-value target for your climate and home
- the age and condition of the house
- access to the attic, walls, crawlspace, or basement
- whether old insulation must be removed first
- air-sealing or other prep work
- local labor rates and regional market conditions

R-value is a simple way to describe how well insulation slows heat flow. A higher number means more resistance to heat moving through the area. But more is not always better forever. There can be diminishing returns after the recommended level for your climate zone. For general cost education, you can review costs. Always get the exact scope of work, material type, and final R-value the job is expected to reach in writing before you pay a deposit.

Rebates, utility programs, and tax credits can change

Information about rebates, utility incentives, and federal energy-efficiency tax credits is provided for general awareness only. Programs change. Amounts, deadlines, covered products, income limits, and eligibility rules can vary by utility, state, zip code, and tax situation.

Because of that, Thermline does not guarantee that any homeowner will qualify for a rebate, incentive, or tax credit. We also do not file applications or tax forms for you.

Before making a purchase decision, confirm current program details directly with the utility, agency, rebate administrator, manufacturer program if relevant, or a qualified tax professional. You can also review our terms and privacy pages for more information about how our service works.

You must verify installers, permits, and job details yourself

Homeowners should hire licensed and insured insulation installers where required and should verify the license and insurance themselves before signing an agreement. Do not rely only on verbal claims.

You should also confirm:
1. the exact areas to be insulated
2. the material being installed
3. the target R-value after the work is complete
4. whether removal of old insulation is included
5. who is responsible for permits, if permits are required locally
6. the cleanup plan and warranty terms
7. the payment schedule and deposit amount

Safety, code compliance, permit requirements, and final installation practices are the responsibility of the installer and, where applicable, the homeowner. Follow your local building department's rules and ask questions if anything is unclear.

By using Thermline, you understand that we provide information and introductions only. Final hiring decisions, contract review, and project oversight are your responsibility.
