Why Spray Foam Matters

Get the Maximum R-Value
For Ultimate Home Comfort

Drafty rooms, uneven temperatures, and rising energy bills are often caused by air escaping through gaps traditional insulation can’t fully seal. Spray foam expands into those spaces, creating a tighter thermal barrier around your home.

  • Spray foam expands into cracks and gaps that batt or blown-in insulation may leave exposed.
  • A tighter air seal helps keep heated and cooled air inside your home year-round.
  • It’s especially effective around framing, plumbing, wiring, additions, and other irregular spaces.

Properly applied spray foam creates both an air seal and an insulation barrier in a single application.

When Should I Add Spray Foam Insulation

5 Signs Your Home May Benefit From Spray Foam Insulation

Cold air leaking through an electrical outlet and along the baseboard of a living room wall

Noticeable Drafts Near Walls, Floors, Or Outlets

Cold or warm drafts near walls, floors, or electrical outlets often point to air leaks.

Rooms That Are Hard To Keep Comfortable

Rooms that never quite reach the thermostat temperature can mean poor insulation nearby.

Rising energy bill on a table beside a thermostat and air vent

High Heating Or Cooling Bills

Escaping conditioned air makes your HVAC system work harder and drives up energy costs.

Ice dam and icicles along a snow-covered roofline caused by attic heat loss

Ice Damming Or Uneven Snow Melt On The Roof

Heat escaping through the attic can cause uneven snow melt and ice buildup along the roofline.

Air leaking through gaps around wiring and plumbing holes in wall framing

Visible Gaps Around Framing, Pipes, Or Wiring

Gaps around penetrations in the attic or crawl space are common spots for air leakage.

Spray Foam Insulation In Stittsville

Most Stittsville homes are newer two-storeys, and many have a bedroom or bonus room over the garage that never feels as warm as the rest of the house. Spraying closed-cell foam under that floor is one of the most effective fixes.

Basements are the other big project. Families finishing a basement in Jackson Trails or Fairwinds often spray the rim joists and walls before framing, so the new space stays warm and dry.

Neighbourhoods we serve in Stittsville:

  • Stittsville Village
  • Jackson Trails
  • Fairwinds
  • Crossing Bridge
  • Granite Ridge
  • Westwood
  • Bryanston Gate
  • Poole Creek
  • Fernbank Crossing

What We See In Stittsville Homes

Rooms Over Garages

Jackson Trails, Fairwinds, Westwood

Cold floors above an unheated garage are a classic spray foam job. Closed-cell foam seals and insulates in one step.

Basements Being Finished

Crossing Bridge, Granite Ridge, Poole Creek

Before the drywall goes up is the ideal time to insulate rim joists and basement walls.

Village And Rural Homes

Stittsville Village and area

Older homes often have drafty rim joists and crawl spaces. Spray foam seals gaps batts can't reach.

How Much Does Spray Foam Insulation Cost

Spray Foam Insulation Cost In Ottawa

Typical spray foam project prices in Ottawa, and when it's worth paying more than traditional insulation.

Rim Joists / Smaller Areas

$1,500–$3,000+

Rim joists, a crawl space, or a section of basement wall. Most projects start around $1,500.

Basements, Attics & Larger Areas

$3,000–$8,000+

Full basement walls, an attic roofline, or a bonus room.

Large Or Multi-Area Projects

$10,000+

Several areas at once, whole-home upgrades, or major renovations.

Spray Foam Is Usually Worth It For

  • Rim joists and basement walls, where air leaks and moisture meet
  • Finishing a basement and wanting a warm, dry space
  • Vaulted or cathedral ceilings with little room for insulation
  • Rooms over garages that are always cold
  • Drafty older homes with gaps around framing, pipes, and wiring

A Cheaper Option May Be Enough For

  • Open attic floors with plenty of space (blown-in is often better value)
  • Topping up attic insulation that's already in decent shape
  • Open interior walls where air sealing isn't the main problem

Why You Should Choose Colair For Your Spray Foam Application

A bad spray foam job can leave a lingering smell, shrink away from the framing, or need expensive removal. Here's how we make sure yours is done right the first time.

  • Conditions checked before we spray

    Surface moisture and temperature affect how foam cures, so we check them first instead of spraying and hoping.

  • Applied in controlled passes

    Foam goes on in layers at the right thickness, so it cures evenly instead of cracking or pulling away from the framing.

  • Thickness measured, not eyeballed

    We check depth across the area to confirm it meets the insulation level you're paying for.

  • Trained application technicians

    Our techs are trained in proper spray foam application, ventilation, and site safety.

The Process

What To Expect On Install Day

1

Free Quote

Tell us about your project and we'll give you a price range, visit to measure if needed, and confirm your written quote.

2

Prep & Protection

Floors, windows, and anything not being insulated are covered, and ventilation is set up before any foam is sprayed.

3

Spray Foam Application

Foam is applied in controlled passes to the target thickness. Everyone, including pets, stays out of the work area.

4

Curing & Re-Entry

The space stays ventilated while the foam cures. Re-entry is often around 24 hours; we confirm your exact time before we start.

5

Cleanup & Walkthrough

We clean up the work area, check coverage and thickness, and walk you through the finished job.

Spray Foam Insulation In Stittsville: FAQs

Need a quick answer? Our team is just a phone call away.

Spray Foam Insulation In Stittsville

Before you frame and drywall. With the walls open, we can spray the rim joists and basement walls quickly and you get a warm, sealed space to finish over.

Send us a few details about your Stittsville home and the area you want insulated. We'll reply with a price range and let you know if we need to see it in person first. Financing is available through Financeit.

Closed-cell spray foam resists moisture and acts as an air barrier, which helps prevent condensation. We check for existing moisture problems before spraying, since those need to be fixed first.

Cost & Value

Closed-cell spray foam typically runs about $3–$6 per sq. ft. installed, depending on thickness, access, and prep. Smaller rim joist or basement jobs are often $1,500–$3,000+, larger areas $3,000–$8,000+, and big multi-area projects can go past $10,000.

It's usually worth it where air sealing and moisture matter most: rim joists, basement walls, vaulted ceilings, and rooms over garages. For open attic floors, blown-in insulation is often the better value. We'll tell you which fits your home when we quote your project.

Sealing air leaks and improving insulation reduces the load on your heating and cooling system, which typically lowers energy costs. How much depends on how leaky and under-insulated the area was to begin with.

Yes. Colair offers financing through Financeit, so you can spread the cost of your project over flexible monthly payments. The application is simple and done online, and you'll get a quick decision. Ask about financing when you request your quote.

Energy-efficiency incentive programs change often and eligibility depends on your home and the upgrade. Ask us about currently available incentives when you request your quote.

Safety & Comfort

Yes. Once fully cured, spray foam is stable. The space is ventilated during application and curing, and you stay out of the area until it's safe to return.

Re-entry is often around 24 hours, but it depends on the product, the area, and ventilation. We confirm your exact re-entry time before the job starts so you can plan ahead.

Everyone, including pets, should stay out of the work area during spraying and until the re-entry time has passed. Once cured, the foam is stable. If someone in your home has sensitivities, tell us when you request your quote and we'll plan around it.

There can be an odour during application and curing, which is why the space is ventilated. A properly mixed and applied foam shouldn't leave a lasting smell once it has cured.

Closed-cell spray foam resists moisture and acts as an air barrier, which helps prevent the condensation that leads to mold. We check for existing moisture problems before spraying, since those need to be fixed first.

The Process

Most residential projects take a few hours to a full day depending on the size of the area being insulated.

We install closed-cell spray foam. It's dense, insulates more per inch than other common insulation, and resists moisture while sealing air leaks, which makes it the standard choice for Canadian homes.

It depends on the space. Damaged, wet, or contaminated insulation usually needs to come out, and open walls are cleared before spraying. We'll tell you what's needed when we quote your project.

In most living spaces, building code requires spray foam to be covered by a thermal barrier such as drywall. We'll let you know if your space needs one.

Choosing A Contractor

Ask whether their installers are certified, which product they use, what the warranty covers for both the product and the workmanship, and how long you'll need to stay out of the house. A good contractor will answer all of these in writing.

For very small jobs, like sealing a few gaps or a small patch, a DIY foam kit may be all you need. Larger areas like rim joists, basement walls, and attics need professional equipment, careful chemical mixing, and proper ventilation, and the work needs to meet building code requirements. That's where hiring a professional pays off.

Yes, spray foam can be added to attics, walls, and crawl spaces in existing homes, not just new construction.
