The basement is next. Make the walls right before the drywall hides them.
Closed-cell foam for basements, rim joists and rooms over garages in Bradford West Gwillimbury, sprayed by CAN/ULC-S705.2 certified applicators and left ready for the Town’s inspection.
Spray foam insulation Bradford houses need is shaped by how new so many of them are. A lot of the work here is a house only a few years old, with a bare concrete basement the family has decided to finish, or a bedroom over the garage that never quite warms up. That follows from how fast the place has grown.
To be clear about which Bradford this is: the town of Bradford in Ontario, part of the Town of Bradford West Gwillimbury in south Simcoe County. Between the 2016 and 2021 censuses, Statistics Canada counted Bradford West Gwillimbury going from 35,325 people to 42,880, a rise of 21.4%. The County of Simcoe’s own summary of those figures puts that among the fastest growth of any municipality in the county, behind only New Tecumseth, and roughly double the 11.2% for Simcoe County as a whole. Private dwellings in Bradford West Gwillimbury reached 13,907 in 2021.
Growth like that leaves a lot of houses that are new enough to have a code-built envelope above grade, and a lot of owners who are now spending money below grade. That is where spray foam does most of its work in Bradford, and it is also where the Town’s building department is paying attention.
The numbers behind it
The chart below is the County of Simcoe’s reading of the 2021 census, trimmed to the south and central municipalities. Bradford West Gwillimbury sits second. Barrie, where we are based, grew at about a fifth of that rate over the same five years.
We are not quoting the census to sound local. It changes what a Bradford job is. A house built in the last two decades already has the above-grade walls and attic the Ontario Building Code asked for when it was built, so the call is rarely “insulate everything.” It is one room, one floor or one wall, and it is usually happening because the owners are adding living space to the house they already have rather than moving.
What the calls are about
Each of these is a place where foam’s air seal does something a batt cannot, and where we will still say so if a cheaper product would do.
Foundation walls and the rim joist above them, sprayed before the studs are closed in. In a Bradford basement finish this is the part the inspector looks at, so it is the part that has to be complete and documented on the day.
A bonus room or bedroom above an attached garage has cold air under its floor all winter. Spraying the floor cavity from below seals it and insulates it in one pass, and in a Bradford subdivision house that is often the only cold room left.
The Ontario Building Code, Article 9.10.9.16, asks for an air barrier between an attached garage and the house so exhaust and fumes stay out. When that wall or ceiling is opened for other work, closed-cell foam closes the gaps around wires and pipes that drywall alone leaves.
A heated garage is only practical to keep warm when the envelope is sealed. Foam handles irregular framing well. If you are building a new detached garage, the Town requires a permit for accessory structures over 10 square metres, so that conversation starts with the Town, not with us.
The permit
Here is the part that catches people. The Town’s homeowner building guide says a permit is required for interior basement finishing, and it names insulation in the list of work that permit covers, next to framing, electrical, plumbing and mechanical. Spray foam on a basement wall in Bradford is permitted work when it is part of a finish, not a weekend upgrade the Town ignores.
The Town’s Basement Finishing handout, updated in 2026, sets out the application:
If the basement is meant to become an accessory dwelling unit, the Town says the separate ADU permit process applies instead. On top of the fee, Bradford West Gwillimbury holds a refundable security deposit of 10% of the construction value, at least $500 and no more than $2,000, and releases it once the permit has had its final inspection.
The Town’s forms make the permit the owner’s application, or an authorized agent’s. What a spray crew controls is whether the insulation stage is ready when the inspector arrives.
The order of work
The Ontario Building Code, Division C, Article 1.3.5.1, lists the stages a permit holder must notify the building official about. One of them is the substantial completion of insulation and vapour barriers. In plain terms, the inspector wants to see the foam before anything covers it. Bradford’s building division says an inspection may be scheduled up to 48 hours after it is requested.
We come to the house in Bradford and get into the basement or under the garage room. The written quote names the area, the product and the thermal barrier the space will need.
We spray once the studs and rough-ins are in, so foam fills behind the wiring rather than being cut around it later.
Lifts go on at documented thicknesses, which is what CAN/ULC-S705.2 requires and what an inspector can check.
Overspray is trimmed and the floor cleared, so the inspection is of the foam, not of a mess.
You or your contractor books the Town’s inspection. Drywall is the usual thermal barrier the Building Code, Article 9.10.17.10, wants over foam in a lived-in room, so it goes up only after the pass.
Choosing who sprays
Foam is one of the few insulation jobs where a bad install is hard to undo. Put these to every spray foam insulation contractor Bradford sends your way, us included.
CAN/ULC-S705.2 is the Canadian installation standard for sprayed polyurethane foam, and it certifies the people holding the gun. Our applicators are certified, and we are a CUFCA member.
A price over the phone for a Bradford basement is a guess. We would rather get into it and measure.
Any foam insulation company Bradford owners hire should be able to answer that in the quote, not at the inspection.
Often it is not. Open, dry stud walls can take batt or BIBS for less, and a good installer says so.
You should get the manufacturer’s re-entry time for your job before work starts, not afterwards.
Ask to see reviews. Ours mention the tidy site more than anything else.
The product
We spray Polarfoam 7300-0 SOYA, a 2 lb closed-cell foam with soya-based content, at roughly R-6 per inch. On a poured foundation that matters for a plain reason: a finished basement gives up floor area to every inch of wall assembly, and closed-cell foam reaches its R-value in less depth than the alternatives. It also bonds to the concrete and acts as the air barrier and, at normal installed thickness, the vapour retarder, which is the layer the inspector is there to look at.
For the room over a garage the same properties apply upside down. The floor cavity is shallow, it is full of joists and ducts, and it is the coldest surface in that room. A sealed layer of foam there tends to be the thing that settles the “why is this bedroom always cold” question, where a batt pushed up between joists leaves gaps for air to move.
Where foam is not the right answer, we will say so. A rim joist and a basement wall are classic foam jobs. An attic that only needs more depth is a different question, and the quote will say which product each area of the house gets.
Barrie-based, on the road to Bradford
We do not have a Bradford office and will not pretend to. We are a mobile contractor based in Barrie, and Bradford West Gwillimbury is one of the Simcoe County communities we cover. Every quote is written at your house, and the foam insulation services Bradford customers book are sprayed from our own rig.
If the foam is part of finishing the basement, yes. The Town of Bradford West Gwillimbury says a permit is required for interior basement finishing, and it lists insulation alongside framing, electrical, plumbing and mechanical work. The application needs a scaled floor plan and a Single Dwelling Unit Declaration, and the Town holds a refundable security deposit of 10% of construction value, between $500 and $2,000, until the final inspection.
Under the Ontario Building Code, Division C, Article 1.3.5.1, the permit holder must notify the building official when the insulation and vapour barrier are substantially complete, so the inspector can see them before they are covered. The Town of Bradford West Gwillimbury says inspections may be scheduled up to 48 hours from the request, so leave that gap between the spray day and the drywall delivery.
Not in an occupied space. The Ontario Building Code requires foam there to be separated from the room by a thermal barrier, usually drywall, or an approved coating where drywall is not practical. We say in the written quote which one your space needs, so the Bradford inspector sees what the plan said.
Most residential jobs we do run one to two days. You stay out of the work area while we spray and until the manufacturer’s re-entry period has passed; for most basements and attics on a lived-in house, people are back the same day. We give you the re-entry time for your job before we start.
No. We are based in Barrie and work out of the truck, quoting every job at the building. Bradford West Gwillimbury is on the list of Simcoe County communities we cover, and our hours are Monday to Friday, 7:30 am to 5:30 pm.
Government and utility programs change often enough that we do not publish one here and let it go stale. Ask when you call and we will tell you what is current for a home in Bradford when you book.
