Open-cell foam insulation in Gastonia NC - a quieter house that stops leaking air

Is open-cell spray foam the right fit for your Gastonia house?

Open-cell foam insulation is a soft spray foam that blocks moving air and insulates in the same coat. Complete Gastonia Insulation Services sprays it in attics, walls and rooms over the garage in Gastonia, NC and the cities around it.

Most people call us about a hot upstairs, a drafty room over the garage or a power bill that won't settle down. Foam costs more than loose fill, and I'll tell you straight that sealing the attic's gaps and topping up the loose fill usually wins, unless your ductwork runs through the attic, because foam under the roof brings those ducts inside the sealed space. The price moves with how much area we cover and how thick the foam goes, whether old or damp insulation has to come out first and what the foam needs over it. I'd rather tell you something needs fixing first than spray over it. The schedule turns on clearing the attic, any permit the job needs and a night or so out of the house while the foam cures, and the estimate gives you the plan and the figure for your house.

What happens after you call about open-cell foam in Gastonia?

  1. Call or send a message

    You call (980) 745-0005 or use the form, and we set up a time for me to come look. We ask for your address early because we work on both sides of the state line, and the address decides which offices cover your job.

  2. I come out and look

    I go up in the attic and check the walls, crawl space or basement, noting what's in the way, from boxes to old insulation to gas equipment. You get an estimate I write myself that shows what has to be fixed first, where the foam goes, what covers it and what it all costs, so nothing shows up later.

  3. We handle permits and repairs

    If you go ahead and the job needs a permit, we take care of the paperwork before anyone climbs a ladder. Then our crew fixes what has to come first, like a damp spot or old insulation that needs to come out.

  4. We spray and clean up

    Our own crew seals and sprays, covers the foam where it needs it and cleans up before we leave. I check the work myself, and you come back in once the wait the foam needs is over.

How we install open-cell foam insulation

Since 2013 we've worked in houses people already live in, so the job usually starts with clearing a path through the boxes. Open-cell stops air well and quiets a room, but it lets moisture vapor pass through, so where we put it matters more than how much. Before spraying, our crew covers any wiring and mechanical equipment in the work area and clears dust off the roof sheathing and framing, because foam won't stick well to a dirty board. Tell us at the estimate if your attic is floored or holds gas equipment, since that shapes the plan. A floored attic is handy for holiday decorations and a headache for foam, because under the state's code rules, flooring beyond narrow walkways and service platforms means the foam needs a full thermal barrier like gypsum board instead of a lighter ignition coating. Not every foam needs a cover at all, so the product we choose and the code decide it together. A gas furnace or water heater up there matters too, because once the attic is sealed, those units should be direct-vent, sealed-combustion models that vent outdoors.

Open-cell usually goes in the attic or the walls, and the crawl space underneath is a separate job, because damp ground needs something that stops vapor. That's where a crawl space vapor barrier does the work, and we often do the two together. For shops, offices and other buildings, we spray open-cell as part of our commercial insulation work.

Open-cell foam questions from Gastonia homeowners

How much does open-cell spray foam insulation cost in Gastonia?

Open-cell spray foam in the Charlotte area usually costs about $0.60 to $0.90 per board foot, which is one square foot of foam one inch thick. That's the area's usual price for the foam, not our price, and your total depends on how much area we cover, how thick the foam goes and what has to be fixed or covered first. The on-site estimate gives you the figure for your house.

Should I pick open-cell or closed-cell foam for my house?

Pick open-cell when you mostly want to stop drafts and quiet the house, and closed-cell when the foam also has to block moisture. Open-cell rates about R-3.6 per inch, R-value being how well insulation slows heat, while closed-cell rates about R-6 per inch, is rigid and hard to compress, and stops vapor at typical thickness. For an attic over living space, open-cell is usually the better buy, and I'll tell you at the estimate if your house calls for closed-cell foam instead.

How long does it take before my family can go back in after spray foam?

Some foam makers recommend waiting 24 hours after spraying before anyone moves back in, though it can vary by product, so plan on a night away. The wait is there because vapors, mist and dust from spray foam can cause asthma, breathing trouble, lung damage, and skin and eye irritation during and after the work. We'll tell you the re-entry time for the foam we use, so you know when the kids and pets can come home.

Who issues building permits in Gastonia NC?

Gaston County Permitting issues construction permits for Gastonia, after the applicant first gets a zoning permit from the City of Gastonia as the city's go-ahead. The county's Building Inspections Department enforces the state building code in Gastonia, so that's who inspects. When your job needs a permit, we check which city and county offices cover your address and handle the paperwork before work starts.

What should I ask a spray foam contractor in Gastonia before hiring one?

Ask whether they're licensed and insured, and whether the crew measures the wood's moisture and checks the weather against the foam maker's guidance before spraying. North Carolina law requires a licensed general contractor once a project's total cost reaches $40,000. We're licensed and insured, and you're welcome to ask me the rest at the estimate.

What causes moisture problems in an attic sealed with spray foam?

Moisture builds up when foam under the roof deck seals the attic and nothing is set up to remove the damp air that collects inside. A sealed, unvented attic becomes part of the conditioned house, so it needs a way to take out moisture like any other room. I plan for that before we spray, because fixing it afterward means working around foam.

  • Commercial insulation

    If you run a shop, office or warehouse that's drafty or loud, we bring the same foam and the same order of work to commercial buildings.

  • Crawl space vapor barrier

    Cold floors and a musty smell from below usually point to the crawl space, and a barrier over the ground keeps that damp out of the house.
