Spray Foam Insulation in Milton, Ontario
Super Sprayers insulates homes and rural properties across Milton, about 35 minutes from our downtown Guelph shop via Highway 401. Since 2018 our certified crews have completed more than 800 spray foam jobs, and Milton brings us a very particular kind of work. Most of the town was built in the last 25 years, and the most common call we get from Milton homeowners is about one specific room in the house.
Milton was one of the fastest-growing communities in Canada through the 2000s and 2010s, adding neighbourhoods like Hawthorne Village, Beaty, Dempsey, Clarke, Harrison and Willmott in quick succession. Houses built at that pace were insulated to the code minimum of their day, and many share the same weak spots: a bedroom over the garage that never warms up, basements with half-height blanket insulation and attics that could use a top-up.
The town isn't all new, though. Old Milton around Main Street has brick homes from the 1800s and early 1900s, and the countryside toward Campbellville and the Niagara Escarpment is horse country, with barns, indoor riding arenas, hay storage and equipment shops. Our installers are CUFCA certified, WSIB covered and follow the CAN/ULC-S705 installation standard on every one of those buildings.

Cold Rooms Over Garages in Milton's Newer Neighbourhoods
If your bonus room over the garage is always a few degrees colder than the rest of the house, you are far from alone in Milton. The batts in the floor under that room sag, cold garage air washes underneath, and the heating duct running to the room loses its heat on the way. More heat from the furnace doesn't fix it.
We open the garage ceiling, spray closed cell foam against the subfloor and seal the ducts, then close it up again. The process is explained on our between-floor insulation page, and our garage insulation page covers the rest of the garage.

Upgrading Builder Basement Insulation
Many Milton basements came with a blanket of insulation covering the top part of the foundation wall and poly over it. Before you finish the basement, that blanket should come off. Spraying closed cell foam directly to the concrete gives a continuous layer from floor to ceiling and removes the need for plastic.
See our basement spray foam page for how it works and what it costs.

Heritage Homes in Old Milton
The older streets around Main Street, Martin Street and Mill Pond have brick houses that predate the subdivisions by a century. They need a gentler approach, focused on the attic, rim joists and basement, with walls insulated only during renovations. Heritage properties may have rules about exterior changes, although interior insulation usually isn't affected.
Horse Farms and Rural Properties Around Campbellville
The rolling land near Campbellville, Mohawk Park and the escarpment is home to horse farms, riding arenas and hobby farms. Steel-clad barns and arenas sweat, drip and let the wind straight through. Closed cell foam stops the condensation and drafts, and a protective coating goes over it where people and animals are present.
Our agricultural spray foam page covers barns, arenas and farm shops in detail.

Milton Homeowner Questions
Why is the room over my garage always cold?
The batts under the floor have sagged, letting cold garage air flow underneath the room, and the duct feeding it loses heat in the cold cavity. Spray foam from below fixes both.
Should I spray foam before finishing my basement?
Yes, it's the best time. The builder blanket comes off, foam goes on the concrete and you frame in front of it with no poly needed.
Do you insulate horse barns and indoor arenas?
Yes. Steel-clad barns and arenas are well suited to closed cell foam, with a coating where required.
