Spray foam insulation in Escondido CA - an attic sealed against heat and drafts
Hot upstairs, drafty rooms or ducts baking in the attic? We spray foam where it fits your house so air stops leaking through.
Have us check your attic first
Call (442) 281-9783 or send the form, and I'll start by looking at what's already up there, because foam sprayed over a problem only hides it.
Is spray foam the right insulation for my Escondido home?
Spray foam insulation is foam our crew sprays under the roof, into walls or under floors in your Escondido home, where it insulates and stops air in one layer, so drafts and attic heat stop working their way into your rooms.
Most of the calls I get come from older houses where the upstairs runs hot, the room over the garage never feels right and the ductwork sits in the attic all afternoon, and that's the kind of house foam helps most. The price moves with how much area gets foam, which type we use, whether old insulation has to come out first and how easy the space is to reach, and the schedule mostly turns on the permit and the time your household spends out while the foam cures. Your written estimate gives you the price for your house and the steps in order.
Why Escondido homeowners call ThermaFit for spray foam
I look at every job myself
I go up in the attic or under the house before you get a price, and our installers spray with me checking in. You talk to the same person from the first look to the end.
Insulating homes since 2020
We've done this work for six years, mostly in older houses where nobody's sure what's up in the attic. We find that out first, because fresh foam over a soaked layer keeps the problem.
Licensed and insured for city permits
We're licensed and insured. When Escondido issues a permit, the city wants the contractor's active state license, city business license and workers' comp proof, so we line that up before your start date.
On a foam job, the order of the work matters most, because foam sealed over a leak or a wet spot just hides it. Get in touch or call (442) 281-9783 to set up a visit.
How we do spray foam insulation
Before anyone sprays, I go over with you which parts of the house get foam and how that changes the way moisture moves there, because foam stops air and some types stop water vapor too. If the job seals the attic by closing its outside vents, we plan how moisture gets out of it as part of the same work. Old insulation that's soaked or full of droppings comes out first, then our installers spray, and where foam stays exposed and the foam maker or the building code calls for a cover, we add a coating or drywall over it. We also help you plan where your household will stay while the foam cures.
Foam costs more than loose fill, and it earns that when the ductwork lives in the attic. If your ducts are somewhere else, I'll usually tell you that sealing the gaps and topping up with blown-in insulation, loose fill blown through a hose, gets you there for less. Both fall under our attic insulation work, and plenty of houses end up with foam where it counts and loose fill everywhere else.
Foam under the roof deck
This suits a house with the furnace or ducts in the attic, because it pulls that whole space inside the insulated part of the house. Any air the ducts leak still goes toward heating or cooling your rooms.
Foam in the room over the garage
Rooms with odd framing and air coming up from the garage are hard to fix with loose fill. Foam in the floor and walls there is often worth the extra cost.
Dense foam under cold floors
Closed-cell foam, the dense kind that also blocks moisture, can suit a crawl space or the rim around the floor framing where damp air gets in. We talk through that area on its own.
How do you know your house could use spray foam?
Upstairs stays hot
Bedrooms upstairs hold the heat long after sunset, which usually means attic heat is pushing through thin or leaky insulation. Until it's fixed, the AC keeps running hard and the power bill keeps climbing.
Ducts in a hot attic
You can see ductwork running across the attic, and the vents blow warm for a while after the AC kicks on. Every leak up there is cooled air you paid for, lost to the attic.
Drafts at lights and hatch
You feel air moving around can lights, the attic hatch or pipes coming through the ceiling. Insulation alone can't stop that, so the draft and the dust keep coming in until the gaps are sealed.
Cold floors over the crawl space
Floors feel cold in winter and the crawl space smells damp. That often points to air and moisture coming up from below, and waiting lets it work into the framing.
What happens after you call us about spray foam?
Call and set a visit
You call or write, and we set a time for me to come look. I note what's up there and what comes first, then send a written estimate with the steps in order.
Set the date and spray
Once you say yes, we set the date and take care of the permit side when there is one. Our installers do the spraying, and I check in along the way.
Walk the finished work together
Before we leave, I walk you through what went where and how the space looks now. You'll know which areas got foam and which type went in each one.
Spray foam questions we hear
These are the questions Escondido homeowners ask most before foam goes in. If yours isn't here, call and ask about your own house, and I'll tell you what I'd look at first.
How much does spray foam insulation cost in Escondido?
Installing spray foam in the San Diego area usually costs about $3,000 to $11,000 per job, and that's the going rate around here, not our price. Where your house lands depends on how much area gets foam, which type and whether old insulation has to come out first, and your written estimate gives you your own figure.
How much can an insulation contractor ask for up front in California?
Under state contractor board rules, the down payment can't be more than $1,000 or 10 percent of the contract price, whichever is less. Later payments are listed in the contract and match the work completed or the materials delivered.
What is the best way to choose between open-cell and closed-cell spray foam?
Choose by area, since closed-cell foam can be used in any climate and open-cell foam stops air but lets water vapor pass through. Both stop air, so the choice comes down to how moisture should move in that spot, and an attic roof deck and a damp crawl space can call for different answers.
How long do we have to stay out of the house after spray foam insulation?
Federal safety guidance says everyone in the household should be out of the house for at least 24 hours, and that's a minimum, not a target. Indoor conditions or the work days may need adjusting so the space suits spraying, so ask us how we'll set up and schedule the work before you book a place to stay.
Do I need a permit for spray foam insulation in Escondido?
We find out for you before the job by checking with the city or county building office, and when a permit is needed we take care of it and the inspections that go with it. The city says energy code compliance is always required, and some jobs also need energy calculations, figures that show how the house meets the code.
Is a sealed attic safer in a wildfire area of Escondido?
Building science guidance says unvented attics are significantly more fire safe in wildfire areas, because embers and ash get into vented attics through the vents. Parts of Escondido are mapped as moderate, high or very high fire hazard zones, so check the city's fire severity zone map to see where your house sits.
