Saving Ontario's barns since 1975 — full structural restoration, board replacement, heritage preservation, and protective coatings under one roof.
When an Ontario barn starts to lean, sag, or rot, the cost of inaction climbs every season. A loose board lets in moisture. Moisture rots the sill plate. A rotted sill plate transfers load to beams that were never designed to carry it. Within a few winters, a barn that needed a thousand dollars of board work needs tens of thousands of structural repair — or it doesn’t survive at all.
At North Pro Barn Painting, we’ve spent fifty years stopping that cascade. Our family has been repairing, restoring, and painting barns across Southern Ontario since 1975. We work on everything from 1880s heritage bank barns in Grey County to working dairy barns in Oxford County to modern pole sheds outside Barrie. Every repair we make is engineered to last decades, not seasons.
This page covers our complete barn repair and restoration service — structural work, board and timber replacement, heritage preservation, and the protective painting and coating work that finishes every restoration we do. If your barn needs help, this is the team that has been doing it longer than almost anyone in Ontario.
Our barn repair work falls into four broad categories. Most projects involve some combination of all four.
Beams, posts, sill plates, rafters, knee braces, and load-bearing connections. We diagnose what's failing, replace what can't be saved, sister or reinforce what can, and bring your barn back to a state that handles Ontario's snow loads, wind loads, and freeze-thaw cycles. This is the work that keeps a barn standing.
Rotted boards, missing board-and-batten, weathered hemlock or pine siding, blown-off panels after a windstorm. We replace damaged sections with matched material — including old-growth-pattern boards for heritage projects where character matters — and we install with screws and proper fasteners that don't back out the first hard freeze.
Bank barns, timber-frame barns, pre-1900 structures with hand-hewn beams. These barns are worth saving and they're worth saving properly. We work with reclaimed and dimensionally-matched wood, traditional joinery where appropriate, and restoration techniques that respect the original builders' work. This is the heart of what we do.
A restored barn is only as durable as the coating that protects it. We finish every restoration project with industrial-grade polyurethane or elastomeric coatings engineered for Ontario's freeze-thaw climate. As experienced Ontario barn painters, we use Korzite, Sherwin-Williams, Cloverdale, and Benjamin Moore products selected for the substrate and exposure of your specific building.
Most barn deterioration in Ontario follows the same pattern. Knowing what to look for is the first step.
The freeze-thaw cycles between February and April are the most punishing time of year for a barn. Water gets into hairline cracks, freezes, expands, and pries the wood apart. We see this damage most often at the sill plate, around door frames, and at any point where the barn meets the foundation.
Old square nails, rusted-out screws, and shifted hardware mean panels that flap in the wind, doors that don’t close, and roofs that lift in storms. We re-fasten with weather-rated screws and rebuild door tracks where needed.
When a corner sinks, when a beam splits, when a wall begins to bow — these aren’t cosmetic issues. They mean load is being transferred to parts of the structure that weren’t built for it. Catching this early is the difference between a repair and a rebuild.
We work primarily with Korzite, Sherwin-Williams, Cloverdale, Benjamin Moore, and Dulux industrial product lines. Specific product selection is part of every estimate.
Every project follows the same disciplined process. This is how we deliver work that lasts.
We come to your property at no cost. We walk the building inside and out, identify failing components, document what we find with photos, and give you a written estimate that breaks down repairs by priority. You decide what gets done now and what can wait.
We work around harvest, calving, planting, and biosecurity requirements. We've been on enough working farms to know that disruption costs money — and we plan accordingly.
Pressure washing, sandblasting, scraping, and rust treatment. The quality of preparation determines how long the finished work lasts. We don't shortcut this step, ever.
Repairs and replacements happen in sequence — structural first, then siding, then trim and detail work. We use the right material for the right application and we document every step.
Sprayed and brushed application of premium polyurethane or elastomeric coating, in the colour you choose. We apply to manufacturer specifications for film thickness, recoat windows, and weather conditions.
You inspect the work with us before we leave. If something isn't right, we make it right. Every project is backed by our family guarantee.
CALEDON, ONTARIO
If you own a pre-1950 barn in Ontario, you’re holding a piece of agricultural heritage. Bank barns, gambrel-roof barns, and timber-frame structures were built with materials and techniques you can’t replicate at any reasonable cost today. Saving them is worth doing.
Our heritage restoration work includes:
We’ve restored barns across Grey County, Wellington County, Perth County, Oxford County, and the Niagara region. Many of these buildings now have another fifty years in them — and look the part.
We provide barn repair and structural restoration across Southern Ontario, including:
If you’re in Southern Ontario and you have a barn that needs work, we’ll come to you.
Costs range widely depending on the scope. Simple board replacement and recoating projects start around $5,000 to $15,000. Full structural restoration of a heritage bank barn can run $40,000 to $150,000+. We provide free on-site estimates so you get accurate numbers based on your actual building.
Almost always repair, if the structure is sound. A new pole barn of comparable size costs $80–$150 per square foot in Ontario. Restoring an existing barn typically costs a fraction of that and preserves a building that can't be replicated. We'll give you an honest answer after inspecting your barn.
A typical restoration project runs four to twelve weeks depending on scope, weather, and access. Heritage projects can take longer. We schedule around your farm operation.
Structural and interior repair work continues year-round. Painting and coating work pauses from late November through early April when temperatures and humidity prevent proper coating cure. Winter is the ideal time to book spring and summer painting projects — our 2026 schedule fills up fast.
In most cases, yes. We work in sections and around your operation. Biosecurity protocols, livestock schedules, and equipment access are all part of how we plan a job.
Every project is backed by our family guarantee. Specific warranty terms depend on the scope of work and materials used — we put it in writing before the job starts.
