Homes and rental houses across Midwest City
Most of what we insulate in Midwest City is established neighborhood housing. A lot of it is single-story homes with one attic spread over the whole floor plan, and plenty of them are rentals. I spent years doing upkeep on rental houses around the Oklahoma City area before starting this business, so I know what an attic looks like after a few tenants and a few rushed fixes. We're based in Norman and work this side of the metro often, next door in Del City and up in Edmond too.
Houses like these tend to carry more than one round of insulation laid down by different people, so we find out what the old layers are hiding before anything new goes in. Your price turns on the attic's size, the inches already up there and whether some of it has to come out, and the schedule turns on that plus any city permit, which my written estimate lays out for your house.
Our services in Midwest City, OK
In a single-story house the attic covers every room, and we often find the insulation piled deep in the middle and thin at the edges, right where it was easiest to reach from the hatch. We bring the edges over the outside walls up to full depth and keep the eave vents clear so the attic can still breathe.
When the bedrooms with can lights run hot and the hallway doesn't, warm air is usually slipping through gaps around those lights, the pipes and the attic hatch. We seal those openings first, because insulation laid over a draft works about as well as a sweater in the wind.
Houses that have changed hands or tenants a few times sometimes have insulation that's matted, stained from an old roof leak or full of droppings. We pull that out and clean up before anything new goes in, since fresh material on top just hides the problem.
Rooms that feel drafty along the outside walls often have little or nothing inside those walls. Our wall insulation work fills the empty cavities through small holes we patch afterward, so nobody has to tear out drywall.
Cold floors in winter usually point to a crawl space where the insulation has sagged, fallen or gone missing. I check whether that crawl space has taken on water before we insulate, because insulation under a damp floor won't stay dry or stay put.
The room over the garage and attics with ductwork running through them are where spray foam usually earns its higher cost. Foam seals air and insulates in one pass, so when your ducts live up there we'll talk through whether it's worth it for your house.

How it works when you call us in Midwest City
Call or send us a message
Tell us what you've noticed, like a hot bedroom, a drafty hallway or a power bill that jumped. We set a time for me to come out, and it helps if you're home so you can see what I see.
I look before suggesting anything
I go through the attic or crawl space myself, take photos and explain what's up there before I suggest any work. You get it written up so you can compare it with anyone else's estimate.
We check with the city
Before work starts we check with Midwest City's permit office, and if your job needs a permit we pull it or walk you through getting one. The city says a residential permit is typically reviewed within 3 to 5 days, so we build that wait into the schedule.
We do it, then I check
A crew I've trained fixes whatever has to come first, seals the gaps and puts in the insulation. I go back through and check the finished work against what we agreed on before we call it done.
Midwest City insulation questions
How much does it cost to insulate an attic in Midwest City?
The cost comes down to the size of your attic, how many inches are already up there and whether any old or damaged material has to come out first. How much gap sealing the attic needs and whether you go with blown-in or spray foam move it too. I measure all of that on site and give you a written figure you can hold up against anyone else's.
Do I need a permit to insulate my house in Midwest City?
We check with the city's Community Development department, which issues Midwest City's building permits, before work starts on your house. When a permit is needed, the city's residential checklist says a licensed contractor submits it unless the homeowner is doing the work, so we pull it or walk you through it. Once it's issued, the permit gets posted in a window or another spot where it can be seen, with a copy of the plans kept at the house.
Does an insulation contractor need a license in Oklahoma?
Oklahoma's Construction Industries Board says general contractors don't currently need a state license, but anyone doing or offering licensed trade work needs that trade's license or registration, and you can look up electrical, mechanical and plumbing licensees on the board's site. The board also sends you to the city for local rules, and Midwest City licenses trades such as electricians, plumbers and HVAC contractors. We're licensed and insured, and if your job turns up wiring or ductwork that needs repair, that part goes to someone holding the right license.
How do I find out if my Midwest City house is in a flood zone?
The city's flood zone map shows flood zone outlines for Midwest City and the areas around it, though it notes FEMA last updated them here in 2009. The city's residential permit checklist also asks for flood elevation on sites in or near flood-prone areas. If your house sits low or the crawl space has ever held water, tell me when I come out, because we deal with the moisture before any insulation goes under the floor.
What is the best way to insulate an attic in Midwest City?
For most attics, sealing the gaps and then topping up with blown-in insulation, which is loose fill blown in through a hose, does the job for less money than foam. Spray foam costs more but seals air while it insulates, so I lean toward it when the ductwork runs through the attic. I'll show you which way your attic points and why before you decide.
How long does attic insulation take in Midwest City, and do we have to leave?
With blown-in insulation you can usually stay home while we work, and with spray foam everyone, kids and pets included, stays out until the re-entry time has passed, meaning it's safe to come back inside. That wait comes from the foam maker's instructions, so I give you the figure for the product we'd use, along with how long the crew expects to be up there, in your written estimate.
