Request an estimateSomerton: single-story homes, ducts overhead
Somerton is up the highway from us in San Luis, and it keeps its own character, a city with long-running traditions where people still pay attention to what goes on at City Hall. Most of the houses we go into here are single-story, some older and lived in for a long time, some newer, along with a few small shops and offices that property managers call us about.
On a one-story house, the attic carries everything: the insulation, the wiring to the ceiling lights and, on a lot of homes here, the ductwork. So a Somerton job usually comes down to what's already up there, how tight the attic is to move around in, and whether those ducts change the right answer.
Working in Somerton: permits, licenses and price
Somerton's city code requires building permits for the work its building rules cover, so before we start, we check with the City of Somerton on whether your job needs one, and if it does, we pull it and set up the inspections. Any contractor you hire here should hold an Arizona contractor license from the state, which is separate from the city's own business license, so ask about both. If you have questions about the city's rules, ask us and we'll point you to the right office.
We do the same work in Yuma and the cities around it, but every city has its own rules, so we don't assume what applies there applies here. Price moves with the size of the attic, how many inches are already up there, whether old insulation has to come out first and how many gaps need sealing. The schedule turns on the permit, if there is one, and on whether removal comes before the install. I look at your attic in person and go over what it needs before I write up the estimate.
Services in Somerton, AZ
Attic insulation
Older attics here often have a few thin, packed-down inches, thinnest at the edges. Our attic insulation work brings the depth up evenly without burying the eave vents.
Attic air sealing
Hot rooms usually trace back to gaps around can lights, pipes and the attic hatch. We seal those first, so new insulation isn't fighting a draft.
Spray foam insulation
When ductwork runs through the attic, foam on the roof deck puts those ducts inside the insulated space. It costs more, so we suggest it only where the ducts justify it.
Blown-in insulation
Blown-in insulation is loose fill blown through a hose, and it tops up an attic with little mess below. Once the gaps are sealed, it's usually the right call.
Insulation removal
Old insulation that got soaked or filled with droppings has to come out before anything new goes in. Laying fresh material over it just buries the problem.
Commercial insulation
Property managers call us about shops and offices with high power bills and hot back rooms. We look at the roof space and walls and quote what the building needs.

Frequently asked questions
Will insulating my older house in Somerton mean bringing it up to code?
Not by itself, because Somerton's building rules don't require changes to a house that was already built under a lawful permit or other lawful approval. The new insulation work is its own question, and whether it needs a permit is something we check with the city before we start, the same as on every job.
What building code covers houses in Somerton, AZ?
Houses in Somerton fall under the International Residential Code, which the city adopts as its own building code with some local changes. The energy rules, the part that touches insulation, come from the International Energy Conservation Code.
Who licenses insulation contractors in Somerton, AZ?
Contractors working in Somerton are licensed by the state through the Arizona Registrar of Contractors, not by the city. State law bars contracting without a license, apart from the few people it exempts, and the city's business license is a separate matter on top of that. We're licensed and insured.
How much does attic insulation cost in Somerton?
Your price comes from what's already in your attic, and you get it in writing from a free on-site estimate. Sealing the gaps and topping up with blown-in usually costs less and does the job, while foam earns its higher price mainly when the ductwork runs through the attic. I'd rather tell you that than sell you foam you don't need.
How long does spray foam take before we can go back in the house?
You stay out until the re-entry time passes, which is the wait the foam maker sets before anyone comes back inside. I tell you that wait at the estimate, before anything is booked, so you can plan for the kids and pets. Blown-in loose fill is different, and you can usually stay home while we work.
How do I check the flood zone for my house in Somerton?
Look up your address on FEMA's flood map viewer, which FEMA calls the best place to start for official flood hazard maps. It's worth checking before crawl space or vapor barrier work, or anything else flooding could affect.
