Centre Wellington, about 25 minutes north
Spray Foam Insulation in Fergus and Elora
Super Sprayers insulates homes, farm buildings and new builds across Fergus, Elora and the rest of Centre Wellington, about 25 minutes north of our downtown Guelph shop along Highway 6 or Wellington Road 7. Since 2018 our certified crews have completed more than 800 jobs, and Centre Wellington is some of the most rewarding country we work in. It also has some of the most demanding buildings for an insulation contractor anywhere in our service area.
Both towns were built by Scottish settlers in the 1830s and 1840s using the grey limestone that lines the Grand River and the Elora Gorge. Many of those stone homes, mills and shopfronts are still standing and still lived in, and they can't be insulated the same way as a modern wood-framed house. Solid stone walls need a moisture-aware plan, and heritage properties may come with extra rules.
Around the towns, Centre Wellington is working farm country, with dairy barns, drive sheds and equipment shops on nearly every concession road. And on the edges of both towns, new subdivisions are adding young families every year. Our installers are CUFCA certified, WSIB covered and follow the CAN/ULC-S705 installation standard, whatever the age of the building.

Insulating Limestone Homes in Centre Wellington
A solid limestone wall stays dry because heat from inside the house warms it and helps it dry out through the stone. Insulating the inside face cuts off that heat, so the stone runs colder and wetter through Wellington County's freeze-thaw winters. Joist ends buried in the stone are especially vulnerable.
That doesn't mean stone homes can't be insulated. It means the attic, rim joists and basement usually come first, and walls are handled with a plan for moisture. Our older and stone homes guide walks through the safer order and the options for stone walls.

Heritage Downtowns and Exterior Changes
Downtown Elora and Fergus are full of heritage buildings, and some properties are designated under the Ontario Heritage Act. Interior insulation normally leaves the exterior untouched, so it rarely conflicts with heritage rules. If your work affects the outside of a designated property, such as new vents or siding, check with the Township of Centre Wellington before starting.
Farms and Drive Sheds Around Centre Wellington
From Belwood to Salem and out toward Alma, the farms around Fergus and Elora rely on pole barns, drive sheds and shops that sweat and drip every spring and fall. Closed cell foam sprayed directly to the steel stops condensation and drafts. We schedule farm work after harvest or in winter when equipment can be moved.
See our agricultural spray foam page and metal building insulation page for thickness and pricing guidance.

New Subdivisions in Fergus and Elora
Both towns have grown quickly, with new neighbourhoods on the edges of each. Builders working here can book spray foam for walls, rim joists and basements between framing and drywall, as explained on our new construction page. Owners of newer homes often call us to finish a basement with closed cell basement spray foam.

Centre Wellington Questions
Can you spray foam the inside of a stone wall?
Sometimes, but only with a moisture plan. We look at the wall's condition, drainage and joist ends first, and in many homes we recommend upgrading the attic and basement before the walls.
How far north of Guelph do you travel?
Fergus and Elora are about 25 minutes away and fully within our regular area. Larger farm and commercial jobs further north are booked by arrangement.
Do you insulate drive sheds and workshops?
Yes, they're some of our most common rural jobs. Closed cell foam goes directly on the steel to stop condensation.
