Is insulating my basement walls worth it?

Basement insulation in Bel Air South lines the inside of your foundation walls so the basement holds its heat through the winter instead of losing it into the ground around the house.

Most calls I get about basements start with cold floors upstairs, a musty smell down below or a power bill that seems high for the size of the house. Some folks are getting ready to finish the space and want the walls planned right before any drywall goes up, which is the easiest time to get it right.

What moves the price is how much wall there is, which material suits your foundation, whether old insulation has to come out and whether a water problem has to be fixed before we start. The schedule mostly turns on that water work and on clearing the walls so we can reach them, and the written estimate I give you after my visit spells out your own figure.

  • Old insulation that's wet or moldy comes out first, and our insulation removal work handles that.
  • We seal the gaps around pipes, wires and the top of the foundation wall while we're down there.
  • If you're finishing the basement later, we plan the insulation now so the framing goes up around it.

What happens after you call about your basement?

I'm the one who comes out to look, and our installers do the work in the order we agree on. Here's how it goes from your first call to the walkthrough at the end.

  1. Call or send us a note

    Call (410) 836-5406, email hi@belairsouthinsulation.com or use the form on this page, and we'll set up a time for me to come see your basement. It helps to jot down where you've seen water and roughly how much wall you want covered.

  2. I walk the basement with you

    I check the walls for water, look at what's on them now and ask how you use the space, then walk you through what I'd do first and why. You get a written estimate that lays out the order of the work, the materials and the price.

  3. Our installers do the work

    Our installers work in the order we talked about, and I check in on the job as it goes. If anything turns up electrical, plumbing or heating work, we bring in a licensed trade for that part.

  4. We go over the finished walls

    Before we leave, I walk the finished job with you, show you what went where and answer whatever questions are left. Satisfaction guaranteed on every job.

How we handle basement insulation

If water's getting in through the walls, that gets fixed before we insulate a thing, because insulation over a leak just hides it and holds the wet against the wall. Rain should also be headed away from the foundation, so I look at where the downspouts empty and how the yard slopes before anything else. Once the walls are dry, we talk through which materials can sit right against the foundation and which ones need to be kept off it, and that choice shapes the rest of the job. For walls that have ever been damp I lean toward foam on the foundation, even though it costs more, because it handles moisture and stops drafts in one layer. A framed wall with batts is fine when the walls stay dry and you're finishing the room anyway.

Foam does a lot of the work in basements. Closed-cell foam insulation, the dense kind that blocks moisture, goes straight onto foundation walls with a history of dampness. Open-cell foam insulation is softer and lighter, and it suits dry walls and the floor framing overhead. If the upstairs runs cold too, attic air sealing, which closes the gaps up top, is often worth a look, since that's where a lot of drafts start.

  • Closed-cell foam on the foundation

    This suits basements where the walls run damp now and then, or where you don't want to give up floor space to a framed wall. It costs the most of the three, and it's the one I recommend when moisture is part of the story.

  • Rigid foam boards glued tight

    Foam panels suit a flat, even wall and often cost less than spray foam, as long as they're stuck down fully with no air gaps behind them and every edge and seam sealed tight. If your wall is too rough for that, I'll tell you and we'll go another way.

  • A framed wall with batts or cellulose

    This suits a basement you're turning into a real room, with walls that stay dry, because the batts or cellulose go inside a stud wall built to keep them off the foundation. It's usually the lower-cost route, but it won't hold up on a wall that gets wet.

What basement insulation looks like on the wall

These photos show the kinds of materials and wall setups we talk through on a basement visit. They're general pictures of the trade, so ask me which one fits your foundation.

  • A worker in protective gear sprays foam insulation into exposed roof framing.

  • An attic with loose yellow insulation filling the floor between wooden joists.

  • White blown-in insulation covers an attic floor beneath exposed wooden roof trusses.

  • A spacious attic has a deep layer of white loose-fill insulation across the floor.

  • A worker wearing a respirator uses a wide hose to remove loose insulation from attic floor joists.

  • Crawl space with a white plastic vapor barrier covering the floor and walls, with exposed joists, insulation, ducts, and pipes overhead.

Basement insulation questions we hear in Bel Air South

These are the questions homeowners ask me most while we're standing at the bottom of the basement stairs. If yours isn't here, call (410) 836-5406 and I'll talk it through with you.

Will insulating my basement walls warm up the rest of the house?

Usually, yes, because a basement that holds its heat tends to keep the first floor above it warmer too. Warmer floors are often the first thing people notice, since nobody enjoys cold feet at the coffee maker.

How much does basement insulation cost in Bel Air South, MD?

Insulation in the Baltimore area usually costs about $1 to $5 per square foot, and that's general pricing across insulation work, not a basement quote of ours. Where your job lands depends on how much wall there is, the material, whether foam needs a cover and whether water repair comes first, and the written estimate after my visit gives you the real number.

What is the best way to insulate basement walls that get damp?

Closed-cell spray foam handles moisture better than any other insulation used on the inside of a foundation wall, and it seals out drafts at the same time. Open-cell foam also seals air well, but it has to go on thicker before it slows moisture moving through the wall, so it's a better fit for walls that stay dry.

Does spray foam in a basement have to be covered?

Yes, spray foam needs a cover, either an ignition-barrier paint, which is a fire-protective coating, or drywall over it. We plan that cover into the estimate so it isn't a surprise at the end.

How do I keep a finished basement wall from trapping moisture?

Keep plastic sheeting and foil-faced sheathing off the inside of fiberglass or other fibrous insulation in a basement, because those layers can trap moisture in the wall. Before the drywall goes up, ask what's covering the insulation, and if the answer is plastic, ask why.

Who can I hire to insulate my basement in Maryland?

Hire a contractor licensed by the Maryland Home Improvement Commission, because only licensed contractors can contract with homeowners for home improvement work, which includes altering or repairing a house. Hiring licensed also puts you under the state's Guaranty Fund, which can repay money you actually lost to poor work or a job left undone, up to what you paid that contractor and no more than $30,000. We're licensed and fully insured.
