Older homes and rentals across Del City
Del City is mostly older, single-story houses on close-set streets. A lot of them are brick ranches with low attics you cross on your hands and knees, and a good share are rentals. I spent years doing upkeep on rental homes around the Oklahoma City area, so these attics are familiar, and they look a lot like what we find next door in Midwest City and over in Warr Acres. We're an insulation contractor based in Norman, and in Del City we hear from homeowners, landlords and property managers alike. Decades of roof repairs, new light fixtures and plumbing changes leave holes in the attic floor, and the insulation is usually piled up in the middle and thin out at the eaves, where the roof comes down too low to reach easily.
Price and schedule usually turn on the same things here: how much old insulation is up there, whether it's wet or full of droppings and has to come out first, and how many gaps need sealing before anything new goes in. If the city wants a permit or an inspection, that adds a step to the schedule. My written estimate puts down your own house's figures, because in an older Del City house, what's already in the attic decides most of the job.
Our services in Del City, OK
Older Del City houses collect holes in the attic floor around can lights, plumbing pipes and the hatch, and that's usually where drafty rooms and a high power bill start. We seal those gaps before any insulation goes in, because insulation laid over a draft is like a sweater with the wind blowing through it.
In a low ranch attic, the insulation tends to end up deep in the middle and thin at the edges, where nobody wanted to crawl, and that's backward. We blow in loose fill evenly out to the eaves and set baffles, short chutes that keep insulation off the vents, so the attic can still breathe.
Rentals and older houses often have insulation that was soaked by an old roof leak or taken over by mice and squirrels. We bag it out and clean up before new material goes in, because fresh insulation over a mess just keeps the mess.
Cold floors in the back bedrooms usually mean the house sits over a crawl space where the insulation has fallen down or was never there. We replace what's missing under the floor and seal around the pipes and wires that come up through it.
Some older Del City houses have little or nothing in the outside walls, which you feel as a cold wall behind the couch in winter. We can blow insulation into closed walls through small holes and patch them, so nobody has to tear out drywall.
Not many Del City houses have a basement, so when one does, it's often a cold, damp room nobody quite trusts. For basement insulation, we look for where water is getting in first, because insulation against a wet wall only hides the problem.

What happens when you call us about a Del City house
Call or send a message
Call (405) 561-8031 or fill out the form and tell us what you've noticed, like a hot back bedroom or a drafty hallway. We'll set a time for me to come out, and on a rental we can meet a tenant or a property manager instead of you.
I walk the attic myself
I go through the attic or crawl space, take photos and explain what I see before I suggest any work. Then I write it up so you can hold it next to anyone else's estimate.
We fix, seal, then insulate
A crew I've trained handles whatever has to come first, like pulling ruined insulation, then seals the gaps and puts in the new material. If the job needs a Del City permit, we pull it or walk you through getting one before work starts.
I check it before we're done
I check the finished work against what we agreed on before we call it done. If the city has to inspect, that inspection must be booked at least 48 hours ahead, so we set it up while the work is still going.
Del City insulation questions answered
Who do I ask about a permit for insulation work in Del City?
The city's Permits Desk takes residential permit applications in Del City, and it's the place to ask whether your insulation job needs one. We check with the desk before any work starts, and when a job calls for a permit, we pull it or walk you through getting one. The desk is open Monday through Thursday from 7:30 AM to 5:30 PM and Friday from 7:30 AM to 11:30 AM.
Does an insulation contractor need a city license to work in Del City?
Del City has its own Residential Contractor License, and a contractor gets it only after showing general liability insurance with at least a $50,000 limit, plus workers comp insurance or an exemption. The state's Construction Industries Board doesn't license general contracting, but anyone doing electrical, plumbing or mechanical work in Del City needs both a state and a city license, which matters if your job means moving wiring for a light or a bath fan. We're licensed and insured, and it's fair to ask any contractor to show you their paperwork before they start.
Can I insulate my own attic in Del City or do I need a contractor?
If you own the house and live in it, the city may approve you doing basic remodeling work yourself, as long as you get the permits and inspections it requires. Rental houses are different, since the city requires licensed contractors on rental property, so landlords should plan on hiring the work out. Either way, I'm glad to come look and tell you what should come first.
How much does it cost to insulate an attic in Del City?
The cost comes down to what's already in your attic and what has to happen before new insulation goes in. Hauling out soaked or dirty material, sealing a lot of gaps, a cramped low attic and choosing spray foam all push the price up, while a clean attic that just needs sealing and a top-up keeps it down. Foam costs more and seals air while it insulates, so in most houses I'd seal the gaps and top up with loose fill, unless the ductwork runs through the attic, where foam usually earns its price.
How do I know if my attic needs more insulation?
Look up through the hatch, and if you can see the tops of the ceiling joists, the wood beams the ceiling hangs from, there isn't much insulation covering them. Rooms that run hotter or colder than the rest of the house, drafts around light fixtures and a power bill that keeps climbing are the other usual signs. When I come out, I check how many inches you have in the middle and at the edges and show you the photos.
How long before my family and pets can go back inside after attic insulation?
With blown-in insulation, loose fill blown through a hose, you usually don't have to leave at all, and we cover the area under the hatch and clean up after. Spray foam is different, because the foam maker sets a re-entry time, the wait before people and pets come back in while it cures. If foam is part of your job, I'll tell you that wait before we schedule, so you can plan where everyone stays.
