Des Plaines houses and what's usually up in their attics

Des Plaines gives us a real mix of work, from older houses near downtown to ranches, split-levels and two-story homes on quieter blocks, with apartment and commercial buildings in between. It's much like the housing we see next door in Mount Prospect, and quite different from the larger homes we insulate out in South Barrington.

Up in the attic, that usually means a house that's been worked on more than once. We'll find a layer of old batts, some loose fill someone blew in on top, and maybe a can light or a bath fan that went in later without anyone sealing around it. Before we add anything, we need to know what's there and whether it still works, because new insulation laid over a problem only hides it.

Insulation services we offer in Des Plaines

We do the full range of insulation work in Des Plaines. That covers sealing and topping up attics, removing old insulation, insulating crawl spaces and basements, and spraying foam where it makes sense. Most jobs start the same way. I come out, look at the attic, crawl space or walls, and work out what order the job should go in, because the right fix depends on what's already there and where the air is moving. Commercial buildings get the same look before we price them.

  • Spray foam insulation

    Spray foam earns its cost in Des Plaines attics where the furnace ducts run through the cold space or the rafters are tight. We spray it where it seals and insulates at once, and we'll tell you when loose fill would do the job for less.

  • Attic insulation

    Most of the cold upstairs rooms and high winter bills we're called about in Des Plaines start in the attic. We check what's there, seal the gaps, clear the eave vents and add insulation evenly out to the edges.

  • Blown-in insulation

    Plenty of older attics here have a thin or uneven layer that's settled over the years. We blow in loose fill, insulation that goes in through a hose, to an even depth once the gaps are sealed.

  • Home insulation

    When a house has drafty rooms, cold floors and a power bill that keeps climbing, the cause is rarely in one spot. We look at the whole house, attic to crawl space, and fix it in the order that gets you the most for your money.

  • Insulation removal

    Old insulation soaked by a roof leak or full of droppings has to come out before anything new goes in. We vacuum it out, clean up the space and check what's underneath before we insulate again.

  • Crawl space insulation

    A crawl space under an older Des Plaines house is often why the floors above feel cold in winter. We insulate it after checking for moisture, because insulation in a damp crawl space just holds the water.

  • Wall insulation

    Older houses here can have walls with little or nothing in them, which you feel on an outside wall in January. We fill those cavities with as little patching as the house allows.

  • Air sealing services

    Air sealing, closing the gaps before any insulation goes in, is where most drafty houses start to feel different. We seal around pipes, wires, can lights and the hatch so the insulation isn't fighting a draft.

  • Basement insulation

    Basements in Des Plaines often have a bare rim joist, the wood band sitting on top of the foundation, where cold air pours in. We seal and insulate those spots and the walls so the space holds its heat.

  • Closed-cell foam insulation

    Closed-cell foam, a dense foam that also blocks moisture, fits rim joists, crawl space walls and other spots that see dampness. It costs more than other options, so we use it where that moisture control really matters.

    Explore service

  • Open-cell foam insulation

    Open-cell foam is softer and lighter, and it suits rooflines and indoor spaces where moisture isn't the worry. We use it when sealing an odd-shaped space matters more than packing in the most insulation per inch.

  • Commercial insulation

    Offices, shops and apartment buildings in Des Plaines leak the same way houses do, just on a bigger scale and in harder places to reach. We look first, then plan the work around your tenants or business hours.

  • Crawl space vapor barrier

    A dirt or damp crawl space sends moisture up into the house and into any insulation down there. We lay a vapor barrier, a heavy sheet that keeps ground moisture down, before we insulate.

  • Vapor barrier installation

    Where a wall, basement or crawl space needs one, a vapor barrier keeps moisture from soaking into the insulation. We put it on the right side for our cold winters, since on the wrong side it traps water in the wall.

  • Attic air sealing

    In a lot of Des Plaines attics, warm air escapes through the tops of interior walls, the bath fan and the hatch. We seal those openings before topping up, so the new insulation actually holds the heat in.

    Explore service

  • Retrofit insulation

    Retrofit means adding insulation to a house that's already built and lived in, which describes most of what we do here. We work around finished rooms, old wiring and whatever earlier crews left behind.

Working in Des Plaines: permits, licenses and what moves the price

Before we start an insulation job in Des Plaines, two things get sorted out. One is whether the city needs a permit, and the other is what your job will really involve.

Who signs off on the work here

In Des Plaines, the building official issues permits for altering or repairing a house, and the city's building and code enforcement division runs the code. Insulation isn't on the city's list of finish work that skips a permit, so I don't guess. I check with the city for each job, because a permit only goes out once the work meets the code and the fees are paid.

We take care of any permit and paperwork the work calls for, so you don't have to chase it. What you can check is the contractor. Des Plaines requires building contractors to hold a city contractor license, and anyone doing work there that needs a building permit is treated as one, so it's fair to ask any contractor about it, us included.

  • Ask any contractor whether they hold a Des Plaines contractor license.
  • We check with the city about a permit before we set a date.
  • Permit paperwork is ours to handle, not yours to chase.

What moves the price and the schedule

The price mostly turns on what's already up there. If the old insulation was soaked by a roof leak or is full of droppings, it has to come out first, and that's real work. After that it's how many gaps need sealing, whether we're blowing in loose fill or spraying foam, and how easy the attic is to reach from the hatch.

The schedule turns on the permit check and on what we find. Removal, foam and a tight attic all take longer than a straight top-up. I'll tell you what I can see from the hatch and what I can't know until we're working, and the estimate is where you get the number for your own house.

  • Old insulation that's wet or dirty comes out before anything new.
  • Foam costs more than loose fill but seals air as it goes.
  • Hard-to-reach attics and rooms over garages take more time and care.

What we check for in Des Plaines attics and crawl spaces

These are the problems we look for on nearly every house we see in the northwest suburbs, Des Plaines included. Each one decides whether new insulation actually helps or just covers up trouble.

  • Old insulation that's gone bad

    If the insulation up there was soaked by a past roof leak or has mouse or bird droppings in it, laying more on top keeps the problem in your house. We look at it first, and if it's bad, it comes out before anything new goes in.

  • Gaps around lights and the hatch

    Can lights, plumbing pipes, wire holes and the attic hatch are where warm air slips out of the house. Insulation laid over those gaps still lets the air through, so we seal them first and the insulation finally gets to do its job.

  • Eave vents buried in insulation

    An attic needs air coming in at the eaves and leaving up high, or moisture builds up and shows in the wood framing. We keep those vents open with baffles, simple channels set at the eaves, so the attic keeps breathing after we add depth.

  • Deep in the middle, thin at the edges

    Insulation tends to pile up in the middle of an attic, where it's easy to reach, and run thin over the outside walls, where the heat loss is worst. We work the coverage all the way out to the edges so the rooms along the outside walls feel the difference.

  • The room over the garage

    The room over the garage is usually the coldest in winter and the hottest in summer, because it has outside air on more sides than any other room. We check the floor under it and the walls around it, since that's usually where the fix is.

How we handle insulation jobs in Des Plaines

We've been an insulation contractor in Hoffman Estates, IL since 2017, and we take on Des Plaines jobs the same way we take on the ones close to home. Here's what that looks like.

We find the problem before adding insulation

I started out selling insulation jobs for another company, and I kept climbing into attics with the installers because the sales pitch didn't explain what I was seeing up there. That's still how I look at a house. Where is the air getting in, where is the heat getting out, and what's already up there that nobody checked?

So the order matters to me. We deal with wet or dirty insulation first, then seal the gaps, then clear the vents, and only then add insulation. If your house doesn't need much, I'll say so, and if a job isn't worth doing, I'd rather tell you that than sell it to you.

  • I look at most jobs myself

    When you call about a house in Des Plaines, I usually come out myself to look in the attic, crawl space or basement. Our installers do the work after that, following the plan I put together from what I saw at your house.

  • Permits checked for every job

    We check with the city for every job and handle any permit and paperwork the work calls for. You won't be the one calling the office to find out what's needed or chasing paperwork while the work waits.

  • Licensed, insured, working since 2017

    We're licensed and insured, and we've been doing this work across the northwest suburbs since 2017. Your satisfaction, guaranteed, and if something about the job doesn't sit right with you, I want to hear about it.

  • A straight answer, then your call

    Some houses need a full job and some just need a few gaps sealed and a little more insulation. Call (847) 380-5407 or use the form, and I'll tell you which one yours is before you spend anything.

Insulation questions we hear from Des Plaines homeowners

These are the questions people in Des Plaines ask most when they're thinking about insulation, from cost to the city's permit rules. The answers are short, and I'm glad to go deeper in person.

How much does it cost to insulate an attic in Des Plaines?

The cost depends on what's up there now, how big the attic is and what it needs, so I won't guess at a number before I've looked. The biggest swings usually come from whether old insulation has to come out first and whether foam makes sense over loose fill. Sometimes the smart money goes on sealing gaps and a modest top-up, and I'll tell you if that's your house.

Can I pull my own insulation permit in Des Plaines?

Yes, if you own and live in a single-family home, Des Plaines makes an exception that lets you get the permit yourself. You have to apply in person, or an agent can apply in your name with an original Power of Attorney recorded by the City Clerk, and for an existing house you agree to live there for 12 months. Otherwise the city issues permits only to licensed contractors registered with it, and the city's residential code spells out the details.

How long does a Des Plaines building permit stay valid?

Unless the building official approves otherwise, a Des Plaines construction permit can be canceled if work doesn't start within 60 days of being issued. The same goes if work stops for 60 days once it's started, or if no inspection is requested for 60 days. When a job needs a permit, we plan the work so it doesn't sit.

How do I know if my Des Plaines attic needs more insulation?

Check how many inches are up there and how evenly they're spread, because a thin or patchy layer is the most common reason upstairs rooms run cold. The age of the house matters too, since older houses usually got whatever was standard back then plus whatever later owners added. Winters here are long, with about 121 nights a year at or below freezing in the Chicago O'Hare records, so a weak attic costs you for months.

Is spray foam or blown-in insulation better for a Des Plaines attic?

For most attics here, sealing the gaps and topping up with blown-in insulation is the better value. Foam costs more, and it seals air while it insulates, so it earns its price when your ductwork runs through the attic or the space is too tight for loose fill. I'll tell you which one your attic calls for and why.

Do we have to leave the house during insulation work in Des Plaines?

For air sealing and blown-in work, you usually don't have to leave, though you'll want kids and pets kept away from the crew and the attic hatch. Spray foam is different, because you're out of the house until the re-entry time, the wait before it's safe to come back, has passed. The foam maker sets that wait, and we'll tell you before we start so you can plan around it.
