About Yuma, AZ
Yuma is where we're based, and most of our calls come from here and the cities around it. In one week we might be in an older block house near downtown, a stucco home in one of the newer subdivisions and a metal shop building the owner wants cooler before summer. We also head south to Somerton and San Luis, where a lot of the houses are built much like the ones here.
A lot of Yuma homes are single story with a low roof and an attic you crawl through instead of walk, and the air handler and ducts often sit up there too. That shapes the job, because the tight space near the eaves is where insulation ends up thin and where vents get buried if a crew isn't careful.
Services in Yuma, AZ
Attic insulation
Many attics we open in Yuma have old fill that's settled flat, deep in the middle and nearly bare along the eaves where the roof comes down low. We even it out and carry it all the way to the edges, keeping the eave vents clear so the attic can still breathe.
Attic air sealing
Hot attic air pushes into the house through gaps around can lights, plumbing pipes, ceiling registers and the attic hatch, and new insulation can't stop a draft still coming through underneath it. We close those gaps with foam and caulk before anything else goes down, because that order is what makes the rest of the job pay off.
Spray foam insulation
When the air handler and ducts live in the attic, your air conditioner is pushing cold air through the hottest space in the house all summer. In that case spray foam insulation on the underside of the roof can bring the ducts inside the insulated space, and I'll tell you at the estimate whether your attic is one of those.
Insulation removal
Insulation that got soaked by a roof leak or filled up with droppings doesn't get better when you bury it under new material. We bag and vacuum the old stuff out first, and if the roof is still leaking I'll show you where before anything new goes in.
Commercial insulation
Metal shops, warehouses and buildings with flat commercial roofs take the Yuma sun all day, and a bare metal roof passes that heat straight down to whoever's working under it. We insulate those roofs and walls with foam or another material that suits the building, and we work around your business hours where we can.
Wall insulation
The room over the garage and the bedroom on the west side are the ones people tell us never cool off, and thin or empty walls are often part of the reason. We check what's inside those walls and fill them where it makes sense, once the attic and the air leaks are handled.
What to know about permits and pricing in Yuma
Inside Yuma city limits, permits come from the city's Building Safety Division, and when a job needs one it has to be issued before we start, so the permit can set the schedule more than the work does. Some addresses that say Yuma sit outside the city, so I check whether yours falls under the City of Yuma, Yuma County or another city, and when a permit is needed we handle the paperwork and line up the inspections. If a company from outside the city is bidding your job, ask whether they hold a City of Yuma business license, since the city requires one for outside businesses working inside its limits, and we're fully licensed and insured.
What moves the price here is mostly what's already up there: how many inches you have, whether old insulation has to come out, how many gaps need sealing, how much room there is at the eaves and whether ducts in the attic make foam the better pick. The schedule turns on the same things, plus a permit if your job needs one and any roof leak that has to be fixed before we cover anything. We do the same work out in Fortuna Foothills, where the first question is often which office your address falls under. Your written estimate spells out what we'll seal, what we'll install and what has to happen first.
Yuma, AZ properties and local conditions
Yuma summers make the attic the hottest room on the property, and in many homes here the air handler and ducts sit right in that heat, so the air conditioner cools the air and then sends it through an oven on the way to your rooms. A thin or uneven layer overhead shows up as a bedroom that won't cool down and a power bill that climbs every June. We start with the leaks around lights, pipes and the hatch, then bring the insulation up evenly, and when the ducts are up there we'll talk through foam at the roof line.
Yuma gets only about 3.28 inches of rain in an average year, so when we find wet insulation it's usually a roof leak, a sweating duct or an air conditioner drain line, not the weather. I'd rather show you that and get it fixed than lay fresh material over it.

How it goes when you call us in Yuma
Call or send the form
Call (928) 248-2654 or use the form, and we'll pick a time for me to come out. Someone should be home so I can get to the attic hatch, closets and garage.
I inspect and write it up
I go into the attic, walls or crawl space myself, see how many inches are up there and take a careful look at gas appliances and the old insulation before anyone touches them. You get a written estimate that says what we'll seal, what we'll install and what has to happen first, so you know what you're paying for before we start.
We line up permits first
When your job needs a permit, we file it and wait for the city to issue it before work starts. City review generally runs 5 work days for homes and 15 work days for commercial buildings.
Install, walk through, clean up
My crew and I seal the gaps first and then put in the insulation, and if it's spray foam I'll tell you ahead of time when to leave and when you can come back. When we're done I walk through it with you, and we clean up before we leave.
Frequently asked questions
Do I need a permit to add insulation to my house in Yuma?
The City of Yuma's permit list doesn't name insulation either way, so the Building Safety Division is the office to ask about your address. The city says most projects need permits and that remodel, electrical and mechanical work generally needs a permit and an inspection, while its no-permit examples are things like fencing, painting and minor repairs. If your job touches wiring, the air handler or the ducts, that question will come up, and we settle it before we start.
What happens if insulation work starts before a permit is issued in Yuma?
The city adds an investigation fee on top of the permit fee, set by the building official at a minimum of $50.00, and it's owed whether or not a permit is issued later. The city also wants fees paid and the permit issued before work begins, and all work inspected before it's covered and before the next step starts. That matters with insulation, because insulation is often what covers the work, so we wait for the permit before we begin.
How much does attic insulation cost in Yuma?
There isn't one price, because the cost comes down to what I find in your attic. A clean attic that only needs gaps sealed and a top-up costs the least, while pulling out wet or dirty insulation, fixing what caused it or choosing foam over loose fill all raise it. I'll give you the number in writing after I've been up there.
How long does attic insulation take in Yuma, and do we have to leave the house?
For blown-in insulation, loose fill we blow through a hose, you can usually stay home, and I'll tell you at the estimate how long we expect to be up there. Spray foam is different, because everyone, kids and pets included, stays out until the foam maker's re-entry time has passed, the wait before it's safe to come back in. If old insulation has to come out first, that adds time, since it has to happen before anything new goes down.
What is the best way to insulate an attic for Yuma heat?
Seal the gaps first, then bring the insulation up evenly all the way to the edges while keeping the eave vents clear. Foam costs more and seals air while it insulates, but in most attics sealing and topping up loose fill gets you more for the money. The exception is when the air handler and ducts are up there, and then foam under the roof is usually worth it because it puts the ducts on the cool side.
Should old insulation be removed before adding new insulation in my Yuma attic?
It should come out if it's wet, moldy, full of droppings or crushed, because fresh material laid over it keeps the problem in your ceiling. Dry, clean insulation that's just thin can usually stay and get topped up. If I find a leak or pests behind the damage, I'll show you before we cover anything.
