Jackson Brothers Spray Foam serves Peterborough and Peterborough County from our shop in Havelock, about thirty five minutes east. Most of the insulation companies advertising in Peterborough are based in the city and work outward. We work the other way: we are a rural crew that also covers the city, and we know the townships around Peterborough as well as we know the city itself.
We install 2lb closed-cell spray foam, attic insulation, and complete insulation solutions for homes, cottages, farms and commercial buildings across Peterborough and the surrounding townships, including Douro-Dummer, Otonabee-South Monaghan, Cavan Monaghan and Selwyn. Whether it is a century home in East City, a farmhouse outside Bridgenorth, or a cottage on Chemong Lake, we bring the same closed-cell approach: insulation, air seal and vapour barrier in one application.
Why Peterborough County homeowners call Jackson Brothers
We know the rural side of the county. A lot of Peterborough-based contractors focus on the city. We are based just outside it, in Havelock, and we cover the farms, cottages and small towns around Peterborough as our everyday territory, not an afterthought.
We know farm, cottage and older-home construction. Stone foundations, uninsulated crawlspaces, metal-roofed outbuildings and lake cottages all need different approaches than a standard subdivision build, and closed-cell spray foam is usually the right fix for all of them.
Straight answers on rebates. Insulation upgrades may qualify under Ontario’s Home Renovation Savings Program. We will tell you plainly what your project qualifies for. No inflated promises.

Services that We Offer
We provide a full range of insulation solutions for residential, agricultural and commercial buildings across Peterborough and the surrounding county:
- Closed-Cell Spray Foam: 2lb closed-cell polyurethane foam for basements, crawlspaces, rim joists, cathedral ceilings and full building envelopes. The highest R-value per inch available, with built-in air sealing and moisture control.
- Attic Insulation: Under-insulated attics are the single biggest source of heat loss we find in area homes. We top up, air seal and bring attics to current standards, often the fastest payback of any upgrade.
- Attic Insulation Removal: Old, damp or rodent-damaged insulation is removed safely and completely before new insulation goes in, so nothing gets sealed into your home.
- Batt + Poly & BIBS: For new builds, additions and garage conversions, we install fiberglass batt with poly vapour barrier and blown-in blanket systems to suit the project and budget.
- Intumescent Paint and Fire Barrier Coatings: Where code requires a thermal barrier over exposed spray foam in shops, barns and storage buildings, we apply code-compliant coatings so the project passes inspection.

Serving Peterborough and the county around it
We cover the City of Peterborough along with Douro-Dummer, Otonabee-South Monaghan, Cavan Monaghan, Selwyn and Smith-Ennismore-Lakefield. That includes Bridgenorth, Ennismore, Lakefield, Keene, Douro, Norwood and Havelock, plus the cottage areas around Chemong Lake, Buckhorn Lake and Rice Lake.
Whether it is a home in the city, a farm on the outskirts, or a cottage on one of the lakes, call us for a free assessment: (705) 995-2176.
