Request an estimateBuellton: older ranch homes and newer tracts
Buellton is a small city, and the houses we get into here are a mix. There are single-story ranch homes that have been around a long time, newer tract houses, and a line of businesses along the highway. It's much the same housing we work in over in Lompoc, so the problems we find usually look familiar.
The older ranch homes tend to have low attics with thin, settled insulation and old gaps nobody ever sealed. The newer ones usually have more up there but thin edges, so either way the job starts with sealing and evening things out, not just piling on more.
What to know before insulating in Buellton
Building permits and inspections for Buellton come from the County of Santa Barbara Building and Safety Division, which handles them for the city under a contract, so if your job needs a permit, that office sets the pace before we start. You can call their Santa Maria office at 805-934-6230 yourself, and before any work we check with them about your address, and if they say a permit is needed, we take care of the application and set up the inspections. The price mostly turns on what's already in your attic, whether old insulation has to come out first, how many gaps need sealing and how hard the space is to get into, and the schedule turns on those same things plus any permit. I write your estimate after I've looked at the house myself.
We're based in Santa Maria and come down 101 for Buellton jobs, so we load everything the job calls for before we leave instead of running back for it. I've been doing this since I started the business in 2013, and I still come out myself to look before we quote, because the parts of an attic nobody sees later are the parts that matter most.
Services in Buellton, CA
Attic insulation
A lot of older Buellton ranch homes have a few inches of settled insulation that's deep in the middle and thin at the eaves, which is backward. We check how much you have and bring it up evenly out to the edges without burying the vents.
Attic air sealing
Can lights, pipe holes and the attic hatch leak air in old and new houses here alike, and new insulation can't do much against a draft. We seal those gaps first, so whatever goes on top actually does its job.
Insulation removal
When old insulation has been soaked by a roof leak or filled with droppings, putting more on top just keeps the problem in the house. We pull it out, clean up the attic and start fresh.
Crawl space insulation
Cold floors in Buellton's raised-floor homes usually trace back to a crawl space with little or nothing under the floor. We insulate between the floor framing and make sure it's held in place so it doesn't sag down over time.
Wall insulation
Some of the older houses here have little or nothing in the walls, which leaves rooms drafty no matter how good the attic is. We blow insulation into the wall cavities through small holes and patch them when we're done.
Commercial insulation
Buellton has plenty of restaurants, lodging and shops along the highway, and their owners and property managers call us about hot dining rooms and drafty back offices. We handle commercial insulation on a schedule planned around your business hours.

Frequently asked questions
How do I find out if my insulation job in Buellton needs a permit?
Start with Santa Barbara County's permitting page, which answers what type of permit a project will need. We check your address with the county before any work starts either way, so you won't be left guessing.
Can I file a planning application with the City of Buellton online?
Yes, the city's Planning Department accepts the project application, payment, plans such as site plans and elevations, and its required documents by email. Planning is separate from the county building permit, so if insulation is one piece of a bigger remodel, keep in mind that the two sides go to different offices.
How much does it cost to insulate a house in Buellton?
Your price is set by what's in your attic now and what has to change, not by the size of the house alone. Old insulation that's soaked or full of droppings has to come out first, a lot of open gaps take more sealing time, foam costs more than loose fill, and a tight attic slows everything down. Call (805) 268-7108 and I'll come look so you get a real number.
What causes the room over the garage to stay hot in my Buellton house?
Usually it's thin or uneven insulation over that room plus open gaps around lights, pipes or the hatch that let air move straight through. Rooms over garages often get the least attention when a house is built. We seal those gaps first and then bring the insulation up evenly, edges included.
What is the best way to insulate an older attic in Buellton?
For most older attics, sealing the gaps and topping up with blown-in insulation, loose fill blown in through a hose, is a better buy than foam. Spray foam costs more and seals air as it insulates, so it earns its price when the ductwork runs through the attic. Either way, we keep the eave vents clear so the attic can still breathe.
Do we have to leave the house during spray foam insulation?
With spray foam, usually yes, until the re-entry time, which is when it's safe to come back inside. With blown-in or air sealing work, most families stay home. We'll tell you before the job how long to plan on being out, kids and pets included, since it depends on the product we use.
