How Thermline works

How the process works in 4 simple steps

1. Tell us about your home and project

Start at Get matched. You share basic project details, such as the part of the home you want to improve, the insulation type you are considering, your ZIP code, and how to reach you. If you are not sure what you need yet, that is okay. Many homeowners start with a problem like hot rooms, cold floors, drafty walls, or high energy bills.

2. We review your request and match you with local installers

Thermline is a free matching service. We are not an insulation contractor, and we do not install insulation or inspect homes. Based on the details you provide, we help connect you with licensed, insured insulation installers who serve your area.

3. You speak with installers and compare options

The installer explains what they recommend for your home, such as attic insulation, wall insulation, crawlspace or basement insulation, air sealing, blown-in insulation, batt insulation, or spray foam. Ask what R-value the job is expected to reach. R-value is a simple way to measure how well insulation slows heat flow. A higher number means more resistance to heat movement, but more is not always better once you reach the recommended level for your climate and home.

4. You choose what happens next

You decide whether to move forward, who to hire, and when to schedule the work. Before you pay a deposit, get the price, scope of work, materials, and target R-value in writing. You can also use our guide on how to vet an insulation installer to help compare companies.

You stay in control

Thermline helps with the connection. You make the decisions.

• You choose whether to request matches.
• You choose which installer to speak with.
• You choose whether to get one estimate or several.
• You choose whether to move forward at all.
• You pay the installer you hire directly, not Thermline.

Always verify that any installer you consider is licensed and insured. Ask for the full job scope in writing before any deposit, including the insulation type, the area to be insulated, and the R-value the job will reach. Follow local permit and code rules.

If you want help understanding typical pricing before you compare estimates, see our insulation cost guides. Remember: any prices you see online are only typical ranges and estimates, not quotes. The real cost depends on the area insulated, the R-value target, the material, the home's age and access, removal of old insulation, and your region.

What it costs you

$0. Thermline's matching service is free for homeowners.

There is no fee to tell us about your project. There is no fee to get matched. There is no fee to compare installers.

If you choose to hire an installer, the project cost is between you and that installer. Thermline does not set the project price, collect your final payment, or guarantee a specific cost. If rebates, utility programs, or tax credits may apply, confirm current details and eligibility directly with the program, your utility, or a tax professional.
