Escondido insulation contractor since 2020

ThermaFit Escondido Insulation Services is an insulation contractor based in Escondido, CA, licensed and insured, and we've been insulating attics, walls and crawl spaces since 2020. I came to this work after years of running crew schedules for a busy company, then learned the trade alongside an experienced installer, and I still come out to look at every job myself. We offer 16 insulation services and have pages for 12 of the cities we work in. You can read more about us and how we work.

What to expect from our insulation crew

A good insulation crew looks before it sells, works in the right order and keeps you posted. Here's what that looks like on a job with us, from the first visit to the walkthrough.

  • Problems fixed, not covered

    We check the attic, crawl space or walls first and tell you what needs fixing, so you aren't paying to bury a leak or droppings under new insulation.

  • A schedule we share

    We set the dates with you and send updates as the job moves, so you know when we're coming without having to call and chase us.

  • Permits handled for you

    We check with the city or county building office on every job, and when a permit is needed we take care of it and the inspections.

  • Other trades come first

    If a roof leak or plumbing problem should go to another specialist first, we say so plainly and help you plan our work around theirs.

Insulation contractor services in Escondido, CA

ThermaFit Escondido Insulation Services is an insulation contractor in Escondido, CA, and our 16 services cover a hot upstairs, drafty rooms, cold floors over a crawl space and an attic nobody's checked in years, so your rooms hold their temperature and the power bill stops creeping up. The price mostly comes down to what's up there now: how many inches you have, whether old material has to come out first, how many gaps need sealing and which material you choose. The schedule turns on that same prep, plus whether your job needs a permit and an inspection. Your free on-site estimate lays out the steps in order, in writing.

  • Spray foam insulation

    We spray foam into walls, rooflines and odd-shaped spaces, where it expands to fill the cavity and seal air at the same time. It's often the right pick when your ductwork runs through the attic.

  • Attic insulation

    Is it hot upstairs, or is the room over the garage never comfortable? We check what's in your attic, fix what's wrong underneath and bring the coverage up evenly all the way to the edges.

  • Blown-in insulation

    We install blown-in insulation, loose fill sent through a hose, into attics and closed walls. The layer goes in even and reaches the eaves without burying the vents that let the attic breathe.

  • Home insulation

    For homeowners who want the whole house looked at, we go through the attic, walls and floors and tell you which spots are costing you the most comfort.

  • Insulation removal

    Old insulation that got soaked, crushed or full of droppings stops working, and new material laid over it keeps the problem. We vacuum it out and clean the space so you start fresh.

  • Crawl space insulation

    Cold floors usually trace back to an open crawl space underneath. We insulate under the floor and seal the gaps so the rooms above stay warmer.

  • Wall insulation

    Does an outside wall feel cold to the touch? We fill empty or thin walls in finished homes, usually through small holes we patch afterward, so the drywall stays put.

  • Air sealing services

    We do air sealing, closing the gaps around pipes, wiring, can lights and the attic hatch before insulation goes in. That way the new insulation isn't fighting a draft.

  • Basement insulation

    We insulate basement walls and the rim joists, the framing along the top of the foundation, so the space below the house holds heat instead of leaking it.

    Learn more
  • Closed-cell foam insulation

    Closed-cell foam is a dense foam that also blocks moisture. It suits spots where dampness is a worry, like crawl spaces and rim joists.

    Learn more
  • Open-cell foam insulation

    Open-cell foam is softer and lighter than closed-cell. We use it to fill attic rooflines and interior walls, where it also quiets noise between rooms.

  • Commercial insulation

    For property managers and business owners, we insulate offices, shops and rental units. We set the schedule around your tenants and your hours.

  • Crawl space vapor barrier

    A crawl space vapor barrier is heavy plastic laid over the dirt and sealed at the seams. It keeps ground moisture away from the floor framing and the insulation above it.

    Learn more
  • Vapor barrier installation

    We install vapor barriers on walls, floors and other spots where moisture could reach the insulation, placed on the side that keeps condensation out of the framing.

    Learn more
  • Attic air sealing

    Most attic drafts come through a handful of openings: the hatch, can lights, plumbing vents and wiring holes. We seal those first so the insulation on top can do its job.

    Learn more
  • Retrofit insulation

    Retrofit insulation adds insulation to a house that's already built and lived in, without tearing out walls or ceilings. It's how most older homes get brought up to date.

Insulation work in Escondido and around it

ThermaFit Escondido Insulation Services is based in Escondido, CA, and we work in many cities around it, including Poway and Valley Center. The 12 cities below each have their own page, and if yours isn't on the list, call and ask.

How an insulation job goes with us

  1. Call or write

    You call (442) 281-9783 or send the form and tell us what you're noticing, like a hot upstairs or cold floors. We get back to you within one business day to set a time for me to come out. It helps to know roughly how old your house is.

  2. I look and write it up

    I go up in the attic or under the house, note how many inches are there and what shape it's in, and spot what needs handling first. Then I send a written estimate with the steps in order. It's free, with no pressure and no obligation.

  3. We do the work

    Once you say yes, we set the date together and take care of the permit side when your job needs one. Our installers do the work, and I check in along the way so the steps happen in the order we agreed on.

  4. Walkthrough before we go

    When the work is finished, we walk you through it before we leave, so you see what went in and where. If your job had a permit, we handle the inspection that goes with it. Keep your estimate as a record of what was done.

Insulation questions we hear a lot

These are the questions Escondido homeowners ask most before we climb into the attic. If yours isn't here, ask us about your own house when you call.

How much does attic insulation cost in Escondido?

There's no honest number until someone looks, so I come out, check the attic and send a free written estimate with the steps in order. An attic that just needs a top-up costs less than one that needs cleanup and sealing first. Call (442) 281-9783 to set a time.

Do I have to pay to remove old insulation before adding new?

Only if it has to come out, which is usually when it's been soaked, crushed or filled with droppings, because new insulation over it just hides the problem. If the old layer is dry and clean, we usually leave it and add on top.

How long does insulation take, and do we have to leave the house?

It depends on the size of the space and how much cleanup and sealing come first, so we give you the timing when we set the date together. With blown-in insulation you can usually stay home, but with spray foam you, the kids and the pets stay out until the re-entry time the foam maker sets for coming back safely.

Do I need a permit to add insulation in Escondido?

It depends on the job, so we check with the city's Building Division or the county building office before we start, and when a permit is needed we take care of it and the inspections. Separately, California requires a licensed contractor for any job that needs a permit or costs $1,000 or more in labor and materials.

How do I get my house ready for the insulation crew?

Clear a path to the attic hatch or crawl space door and move anything stored right below it, so our installers can get in and out cleanly. We'll tell you anything else your job needs before the date.

What if something doesn't seem right after the insulation is done?

Call us at (442) 281-9783 and tell us what you're noticing, and we'll get back to you within one business day. Our work is backed by our satisfaction guarantee, and the walkthrough at the end means you already know what went in and where.

Is spray foam or blown-in insulation better for my attic?

For most attics, sealing the gaps and topping up blown-in insulation is the better buy, unless your ductwork runs through the attic. Foam costs more but seals air while it insulates, which pays off when the ducts are up there. I'll tell you which fits once I've seen yours.

Does an insulation contractor need a business license to work in Escondido?

Yes, the City of Escondido requires a city business license from anyone who does business in the city, including contractors based somewhere else. That's separate from the state contractor's license, so it's fair to ask any contractor about both.

Tell us what's going on in your attic

Tell us what you're noticing and how old your house is, and we'll reply within one business day to set a time for me to come look. The estimate is free, on-site and no obligation.
