Request an estimateYuma: single-story homes, hot attics
Yuma has a bit of everything: older block and stucco houses near downtown, long streets of single-story ranch homes, newer subdivisions on the edges, and plenty of manufactured homes and winter rentals. We're based south of here in San Luis, and the Yuma calls sound a lot like the ones at home: a hot back bedroom, a room over the garage nobody uses in July, a power bill that climbs every summer.
A lot of these houses keep the ductwork in the attic, so the air you're paying to cool picks up attic heat on its way to the vents. In the older ones the insulation up there is usually thin and packed down, and that's where we start.
What we deal with on jobs inside Yuma
Inside Yuma city limits, permits come from the city's Building Safety Division, and most projects there need one. The city's list doesn't name insulation either way, so before we start we check with that office, and if a permit is needed we pull it and set up the inspections. That can shape the schedule more than the attic does, because the permit has to be paid for and issued before work begins, and the inspector has to see the work before anything covers it.
One thing you can check yourself is the business license, because a contractor from outside city limits needs a City of Yuma business license to work inside the city. Price moves with what's already in your attic and how much sealing it needs, and I look at both in person before I write anything up. The same crew also works in Somerton and the cities around it.
Services in Yuma, AZ
Attic insulation
Many Yuma attics hold a few inches of old, packed-down fill under a roof that bakes all summer. We build it back to an even depth, edges included.
Blown-in insulation
Blown-in insulation is loose fill sent through a hose, and it suits the open attics over Yuma's single-story homes. We seal the gaps first so it isn't fighting a draft.
Attic air sealing
Desert dust leaves dark streaks wherever air leaks in around can lights, pipes and the attic hatch. We seal those gaps before any new insulation goes down.
Spray foam insulation
When the ductwork sits in a Yuma attic, spray foam under the roof deck pulls it inside the cooled space. It costs more, so that's where we recommend it.
Insulation removal
In older Yuma homes, fill soaked by a roof leak or fouled by rodents has to come out, or new material just hides the problem. We vacuum it out first.
Commercial insulation
Shops, offices and rentals in Yuma run their cooling most of the year, and that shows on the bill. We work around business hours so tenants can stay open.

Frequently asked questions
How much does it cost to insulate an attic in Yuma, AZ?
I give your price after I've been up in the attic, because what's already there decides most of it. The big swings are whether old fill that's flattened, wet or full of droppings has to come out first, how many gaps need sealing, and whether the job is a top-up of loose fill or foam under the roof deck. You get your own figure in writing once I've walked you through what the house needs.
What causes hot rooms in a Yuma house?
Usually it's the attic. Yuma averages about 76 degrees across the whole year, so the roof heats the attic for months on end, and thin insulation, open gaps or ductwork up there pass that heat right down into the rooms. The room over the garage and the bedroom at the end of the longest duct run usually feel it first.
How do I tell if my attic in Yuma needs more insulation?
Look in from the attic hatch, and if you can see the tops of the ceiling joists, there isn't enough up there. A tape measure pushed down into the fill tells you how many inches you have, and fill that's flattened, stained or thin out by the eaves is doing less than it looks. If you'd rather not climb up in the heat, I'll check it at the estimate.
How long does permit review take for insulation work in Yuma?
For homes, the city's permit review usually takes about 5 work days, and commercial projects about 15. When a job needs a permit, we build that wait into the schedule so the crew isn't sitting on a start date.
What happens if insulation work starts before a permit in Yuma?
The city adds an investigation fee on top of the permit fee, set by the building official at $50.00 or more, and it's owed whether or not a permit is issued later. That's why we check with the city before the crew starts, not after.
How long will the insulation crew be in my Yuma house, and do we have to leave?
With blown-in work and air sealing you can usually stay home, and the crew's time up there comes down to how much old material comes out first and how much sealing the attic needs. Spray foam is different, so everyone, kids and pets too, stays out until the foam maker's re-entry time, how long before it's safe to come back in, has passed, and we tell you that time before we start. Before we seal any house tighter, I check that the gas appliances still vent the way they should.
