Leamington Spray Foam Insulation
Leamington, Ontario · all of Essex County
Leamington Spray Foam Insulation provides attic insulation, basement insulation and crawl space insulation to the Leamington area.
Spray foam does two jobs at once. It insulates, and it seals the gaps that batt insulation leaves behind. That second job is where most of the comfort and most of the saving comes from.
We also install garage, new construction, insulation removal, commercial and greenhouse spray foam insulation. Every quote starts with somebody coming out to look at the space.
Give us the building, the room and the season it goes wrong in. Somebody will come and look at it. Or call (226) 286-5239.
Quotes are written and name the product and the installed thickness, not just a total. The number does not move unless the scope does.
If the code wants drywall or an ignition barrier over the foam, that cost is on the quote from the start rather than turning up after the work is done.
We take moisture readings before spraying. If the honest answer is drainage rather than insulation, we say so and decline the job.
Lifts are built up rather than one heavy pass, so the foam cures the way it is supposed to.

Attics through to packhouses. Each one specified against the moisture and the access we find, not off a rate card.
An attic is the cheapest comfort you can buy in most Leamington houses, and it is usually the first thing we look at. Warm indoor air rises, finds every gap in the ceiling, and takes moisture with it on the way out.

Most calls about a cold garage in Leamington are really calls about something attached to it. The bedroom above it, or the kitchen wall it shares with the house.
View Garage Insulation
Closed cell spray foam applied straight onto the foundation wall does three jobs at once. It insulates, it seals the air, and at the right thickness it is its own vapour control layer.
View Basement Insulation
Crawl spaces cause more comfort complaints than anything else we deal with, and almost all of them come down to one design assumption that no longer holds.
View Crawl Space Insulation
The insulation decision changed when the 2024 code came into force. The R-values went up and, more importantly, the emphasis moved toward airtightness and whole-building performance.
View New Construction Insulation
Insulation does not last forever, and in a damp climate it often does not last as long as people expect. When the existing material is wet, mouldy, rodent damaged or flattened, it has to come out before anything new goes in.
View Insulation Removal
Commercial buildings have a different insulation problem to a house. They are large, often steel framed, and usually holding a temperature a long way from the outside air.

We insulate the parts of a growing operation that should be insulated, and we are straight with growers about the parts that should not be.
View Greenhouse and Agricultural InsulationIt seals as it insulates. Foam expands into the gaps around joists, wiring, plumbing and top plates, which is where the air actually moves.
Closed cell foam is its own vapour control layer at the right thickness. In a lake climate that matters as much as the R-value.
It holds its shape. Batts sag, settle and get pushed aside. Foam is bonded to the substrate and stays where it was sprayed.
It does not absorb water, it does not feed mould, and rodents cannot nest in it.
Closed cell adds real racking strength to a wall. Useful anywhere, and Essex County gets more tornado warnings than most of the country.
It fits awkward shapes. Rim joists, brick ledges, the angle where a knee wall meets a roof deck. Batts never fit those properly.
Describe what the room does in February and what it smells like in August. Between those two answers the product picks itself.
The short rule: closed cell wherever moisture is on the other side, open cell where it is not.
Closed cell spray foam runs about R-6 to R-7 an inch, blocks vapour once it is thick enough, and belongs on foundation walls, crawl space walls, rim joists and anything agricultural or refrigerated.
Open cell is around R-3.5 to R-3.8 an inch, costs less, and does not control vapour at all. It suits interior partitions, sound damping and ceilings under conditioned space.
Getting this backwards is the most common fault we are called out to fix.
Depth is the number people ask about. Gaps are the number that matters.
A bathroom fan venting into the attic, an open chase around a plumbing stack, the top plate of every interior wall. A deep layer of insulation with a hole in the middle of it is still a hole.
This is the part that separates a good insulation job from a cheap one, and it is why we take readings before quoting rather than pricing off square footage.
Attic insulation is the cheapest comfort in most houses. Heat rises out through the ceiling, and warm damp indoor air goes with it.
Attic spray foam goes either across the attic floor with the roof left vented, or onto the underside of the roof deck to bring the attic inside the building. Which one depends on how the roof is built and whether there is ducting up there.
Around here it earns its keep in August as much as February. A dark roof drives heat down into the top floor all afternoon.
Basement insulation done with closed cell sprayed straight onto the concrete gives you an air barrier and vapour control in one pass, with no cavity behind it to trap moisture.
That last part is the point. The usual assembly, studs held off the wall with batts between them and poly over the front, leaves a gap of still air against cold concrete. Humid air finds it and condenses there. You smell it before you see it.
Rim joists come with the job. Small area, large share of the leaking, cheapest square footage on the quote.
Most crawl spaces were built vented, on the theory that outside air would dry them out. In a humid climate it does the opposite.
Sealing one means closing the vents, sheeting the ground, and foaming the perimeter walls and rim rather than the joists overhead. The space then sits at the same conditions as the house above it.
Floors get warmer, the musty smell goes, and the framing stops cycling wet and dry through the year. South of town, where a lot of houses sit on crawl spaces instead of basements, this is the single most common job we do.
Most cold garage insulation complaints are really complaints about the room above it or the wall it shares with the house.
That shared wall matters most. It separates living space from a room where a vehicle runs and chemicals sit on a shelf, so it needs sealing for air quality as much as comfort.
The header above the overhead door is usually the worst single gap in the building, and it takes very little foam to fix.
The 2024 code raised the numbers and put far more weight on measured airtightness. An assembly can hit its nominal R-value and still fail a blower door test.
Foam does the sealing and the insulating in one operation instead of relying on a separate membrane being installed perfectly. Flash and batt is often the sensible middle ground on above grade walls.
Book us for new construction insulation at framing stage. The window between rough-in inspection and drywall is tighter than most people expect.
We do not spray over insulation that has failed. Foam bonds to whatever is underneath it, so spraying onto a damp compressed batt seals a wet problem inside a wall where nobody can inspect it.
Wet, mouldy, rodent damaged or flattened material comes out first. It is quoted separately so you can see what that part costs.
If what you have is dry and doing its job, we will tell you it can stay. See how insulation removal works before booking a new install over old material.
Nobody sprays foam on glazing and we would not suggest it. The building exists to let light in.
What does get insulated is everything around the growing area. Headhouses, grading and packing rooms, boiler rooms, cold storage, north gable ends, and perimeter curtain walls below bench height.
With energy curtains handling the roof, the walls become a disproportionate share of the loss, so perimeter work usually pays back fastest. Worth knowing in a town with two thousand acres under glass. See our greenhouse and agricultural insulation and commercial and cold storage insulation pages for the full scope of that work.
A musty smell that shows up in July rather than January.
Floors above a crawl space that feel cold and slightly damp underfoot.
North-side rooms that never come up to temperature whatever the thermostat says.
Bills climbing while the equipment stays the same age.
Rodent runs, matted batts, or insulation gone grey and flat.
Across Ontario in 2026, open cell runs somewhere around one and a half to two and a half dollars a square foot, closed cell roughly three to seven. Those are market ranges, not a quote for your building.
Getting to the work drives the total harder than the foam does. A basement you can stand up in and a crawl space with eighteen inches of headroom might swallow the same material, but one takes a crew twice as long on their backs.
There is a floor on what we can quote. Very small jobs carry a minimum, and you hear that figure before anything is booked.
This surprises most homeowners and a lot of quotes leave it out. Foam in an occupied space cannot be left exposed. It needs a thermal barrier over it, and half-inch drywall is the standard accepted assembly.
Where a space is not normally lived in, an attic or a crawl space, a tested ignition barrier of lesser thickness will usually satisfy the requirement.
If a quote you are comparing does not mention this, ask. It is a real line item.
The 2024 code has been in force since January 2025. For a new build in this zone with high efficiency heating, the current figures are roughly R-50 for a ceiling with an attic, R-31 without one, R-24 above grade walls and R-20 basement walls.
Basement walls nearly doubled, from R-12. That is the change that most often sends a builder toward foam.
Figures vary by compliance package and equipment. Always defer to the building department.
The Home Renovation Savings Program runs to 30 November 2026, delivered by Save on Energy with Enbridge Gas.
There is a standalone attic stream that needs no energy assessment, and a larger multi-measure stream that requires one before work starts. Those two get confused constantly, and being sent for an audit when you only want the attic done wastes your money.
We are not the program administrator and we do not quote amounts. We will tell you which stream your job fits.
Leamington's long, humid growing-season climate is only one piece of the picture, and it helps to see how crews elsewhere plan around their own local conditions. spray foam insulation in Milton works a drier inland climate with a very different moisture profile. insulation services contractors in Saint John deal with a coastal Atlantic climate that brings its own vapour-control questions. Windsor attic insulation specialists face a similar Great Lakes humidity load a short drive west. spray foam contractors services in Bradford plan around a colder inland winter than Essex County typically sees. Every one of these climates asks a slightly different question of the same material.
We come out and look. Moisture readings, substrate temperature, and a check on where the air is actually moving.
You get a written quote naming the product, the installed thickness and the price on one page. If the code wants drywall over the foam, that is on the quote rather than turning up later.
On the day the space is cleared and masked, anything failed comes out, and the crew sprays in lifts so the foam cures properly.
We trim back anything proud of the framing, clean up, and give you a re-occupancy time before we leave.

It cannot, and an installer who tells you otherwise wants the sale more than the outcome. Foam controls air and vapour. Standing water under pressure goes straight past it, and it replaces nothing that drainage does.
Where water is still coming in, the outside gets sorted first. Ground falling away from the wall, downspouts discharging well clear, weeping tile actually running. Insulation comes after that.
In occupied space, yes. The code requires a thermal barrier over exposed foam and half-inch drywall is the standard assembly. In an attic or crawl space, a tested ignition barrier of lesser thickness will usually do.
Get it priced in at the start. It is one of the more common surprises on a cheap quote.
Properly mixed foam has finished curing and off-gassing by the time we hand the space back, usually the same day for residential work.
A chemical smell that lingers for weeks means off-ratio foam, where the two components were not mixed correctly. That does not cure out and cannot be sprayed over. It has to come out.
Because the problem is humidity, not cold. Warm outdoor air carries a lot of moisture, moves inward through the foundation, and condenses on the first cool surface it finds, usually the concrete behind the insulation.
Winter dries a house out. Summer loads it up. Being this close to Lake Erie makes it more pronounced than it would be inland.
Not the glazing. Foam is opaque and the structure exists to let light in.
We insulate the headhouse, packing and grading rooms, cold storage, boiler rooms, north gable ends and the perimeter curtain wall below bench height. On a heated range the perimeter work usually has the shortest payback on the site.
