Spray foam insulation
Spray foam seals air and insulates in one pass, so it earns its higher cost where ductwork runs through a hot attic or a bonus room keeps leaking air no matter what you try.
Insulation Contractor in Apex, NC - Cooler Bonus Rooms and Warmer Floors
Sealcraft Durham Insulation Company is an insulation contractor based in Durham, NC. In Apex, we seal air leaks and insulate attics, walls, crawl spaces and bonus rooms, and we pull out old insulation that's gone bad.
Sealcraft Durham Insulation Company handles attic and wall insulation, air sealing, which closes the gaps air slips through before any insulation goes in, crawl space work, spray foam and old insulation removal for homes in Apex, plus commercial work for property managers. Most Apex calls start with a hot upstairs, a drafty room over the garage or cold floors.
What we find in Apex attics and crawl spaces
A lot of the Apex houses we're in are two-story homes in newer neighborhoods, many with a bonus room over the garage. That room has attic on several sides and an unheated garage under it, so it runs hot in summer and cold in winter. Usually the fix is sealing the gaps around it and filling the spots where the insulation was left thin, not a bigger air conditioner.
Older houses closer to the middle of town tend to have a few inches of tired insulation up top and a crawl space underneath. Before I recommend anything, I measure how many inches are already there and look for soaked or matted spots and droppings, because new material laid over a bad layer just keeps the problem. Then I explain what I found in plain terms.
Apex is one of the cities around Durham we work in, along with Cary and Morrisville next door. The houses there look a lot like the ones in Apex, so the same habits carry over. If you're on the edge of town and not sure we come out to you, just ask.

Insulation services we offer in Apex
Attic insulation
If your upstairs runs hot and the attic has only a few inches left, we seal the gaps first, then bring the depth up evenly, right out to the edges where it's usually thinnest.
Blown-in insulation
Blown-in insulation, loose fill blown through a hose, settles around trusses and wiring in tight attics, and it's usually the most practical way to top up an older layer that's still dry.
Home insulation
When the whole house feels drafty and the power bill keeps climbing, we look at the attic, walls and crawl space together and tell you which one to fix first and why.
Insulation removal
Insulation that got soaked or full of droppings has to come out before anything new goes in, or you just bury the problem. We bag it in the attic and haul it away.
Crawl space insulation
Cold floors over a crawl space usually mean the insulation under them has sagged or fallen. We deal with the moisture that pulled it down, then put it back so it stays up.
Wall insulation
Exterior walls in older houses are sometimes empty or half full. We fill them through small holes from inside or outside and patch the holes when we're done.
Air sealing services
We close the gaps around can lights, pipes, wiring and the attic hatch so your insulation isn't fighting a draft. It's often the cheapest step in the job and usually where we start.
Basement insulation
Where a house has a basement, insulating its walls keeps the floor above warmer and makes the space more comfortable to use, as long as any dampness is handled first.
Closed-cell foam insulation
Closed-cell foam, a dense foam that also blocks moisture, fits rim joists and crawl space walls, where damp air is the issue and soft insulation would just soak it up.
Open-cell foam insulation
Open-cell foam is softer and lighter, and it suits the underside of the roof deck when we're bringing attic ductwork inside the insulated part of the house.
Commercial insulation
Property managers call us for offices, suites and storefronts. I learned this trade on commercial crews, so warehouse ceilings, office buildings and metal walls are familiar work for us.
Crawl space vapor barrier
A crawl space vapor barrier, heavy plastic laid over the dirt, keeps ground moisture from rising into the floor framing. We lap and seal the seams so it stays put.
Vapor barrier installation
In walls, basements and other spots, a vapor barrier on the wrong side can trap moisture instead of stopping it, so we work out where it belongs before we put one in.
Attic air sealing
Before new insulation goes in your attic, we seal the wire holes, top plates and hatch, because loose fill alone won't stop warm air from rising through those openings.
Retrofit insulation
If your house is finished and lived in, retrofit work adds insulation without tearing it apart, working through the attic, small wall holes or the crawl space.

(919) 246-8605Permits, licenses and price on an Apex job
Who issues a permit depends on where your address sits. Homes inside Apex and in its ETJ, the area just outside town limits where the town's development rules still apply, follow the Town of Apex permitting steps, and homes in unincorporated Wake County go through the county. When a job needs a permit, the start date waits on it, so that's often the first thing that sets your schedule.
Apex doesn't require a business license, so there's no town license for a contractor to show you. What you can ask is whether they're licensed and insured, and we are. Before we start, we check with the permit office that covers your address, and where a permit is needed, we handle the paperwork and meet the inspector. We keep that habit everywhere we work, from Apex up to Hillsborough.
Your price mostly comes down to how big the attic is and how easy it is to reach, whether old insulation has to come out first, how many gaps need sealing and whether foam makes sense or loose fill will do. The schedule turns on the permit, on any removal, and with foam, on the wait before you can come back inside. Your own figure comes in the written estimate.
Why Apex homeowners have us look first
I learned this trade on commercial crews, spraying foam and fitting board in warehouses, schools and office buildings, and most of the problems I saw there came from a step someone rushed. I started this business in Durham in 2013 to bring that care to houses. I come out to your Apex house myself, look at the attic and crawl space, and write the estimate before anyone touches a thing.
Our trained installers do the work with a crew lead on site, and they work in a set order. We seal around can lights, pipes and the attic hatch first, so the new insulation isn't fighting a draft, then lay it evenly all the way to the edges, where it's usually thinnest. We're licensed and insured, and our promise is simple. Satisfaction guaranteed.
I'll also tell you when foam isn't worth it. Foam costs more and seals air while it insulates, but sealing the gaps and topping up loose fill usually wins, unless your ductwork runs through the attic. If you want that kind of straight answer about your house, call (919) 246-8605 or send our contact form.
How Apex houses and ground shape the job
Apex has its own mix of houses and ground, and a few things about the place change how we plan the work, how we clean up and what we ask you to keep an eye on.
Runoff heads to Jordan Lake
Apex sits in the Jordan Lake watershed, and the town points out that water running through town ends up in a lake people drink from. So when we pull out old insulation, we bag it inside the attic or crawl space, carry it out sealed and haul it off. We don't leave loose fiberglass or foam scraps in the yard where the next rain can wash them toward a storm drain.
Crawl spaces on Piedmont ground
Apex is part of Wake County's Piedmont, and a lot of the houses we see here sit over crawl spaces on bare dirt. Moisture rising from that ground is usually what pulls insulation down from under the floor and leaves it hanging. We fix the moisture first, usually with a vapor barrier over the dirt, and only then put insulation back where it can stay dry and in place.
Ductwork up in the attic
Many Apex houses run their heating and cooling ducts through the attic, which puts them in the hottest part of the house all summer. When we're up there, we seal the duct joints we can reach and make sure loose fill doesn't crush flexible duct flat. I'll show you photos of what the ducts look like before we talk about whether they change the plan.
Keeping the eave vents open
Most roofs we see in Apex pull fresh air in at the eaves and let it out up high. When insulation gets blown right over those eave vents, the attic stops breathing and moisture starts showing up in the framing. We set baffles, short channels that hold the insulation back, at each vent before any loose fill goes in, so the air keeps moving.
Questions Apex homeowners ask about insulation
How much does attic insulation cost in Apex, NC?
Your price comes down to the attic's size and access, the condition of what's already up there and the material you choose. A dry layer that only needs sealing and a top-up keeps the cost down, while removing soaked or contaminated insulation, choosing foam and working in tight, hard-to-reach attics push it up. I write it out and walk you through each line.
Do we have to leave the house while you insulate?
With blown-in or batt insulation, you can usually stay home, and we keep the mess to the attic and the path to the hatch. Spray foam is different. Everyone, kids and pets included, leaves while it goes in and stays out for the re-entry time, which is the wait the foam maker sets before people come back, and we follow it.
How long will the insulation crew be in my attic?
It depends mostly on how much prep the attic needs, because sealing gaps and pulling out old material take longer than laying new insulation. A bigger attic, more removal and more openings to close all stretch it out, and foam adds the re-entry wait. I'll tell you how long your job should take when I write the estimate.
How do I get ready for insulation work in my Apex house?
Clear a path to the attic hatch or crawl space door and move anything stored around it, because we need room to work and run a hose. Put pets in a closed room and leave space in the driveway for our truck. If you know about roof leaks or animals that got in up there, tell me before we start.
How do I find out who handles permits for my address in Apex?
Wake County's iMAPS property search will tell you. As Wake County planning explains, you enter your address or parcel number, and the Jurisdiction entry shows the agency you'd go through. We check this before every job anyway, so you don't have to look it up yourself unless you want to.
Where do I submit permits to the Town of Apex?
New town development permits and applications go through the town's new MyServices portal, and you'll need to create an account to use it. If your insulation job needs a permit, we handle that paperwork and meet the inspector, so most homeowners never have to log in at all.
What does a business moving into an existing space in Apex need from the town?
It goes through three town steps in order, starting with a Certificate of Zoning Compliance from Planning, then a Commercial Permit Application with Inspections, and last a Fire Inspection Plan Review. That applies whether or not you renovate. If insulation is part of your build-out, we can plan our work around those steps.
