Buying a Log Home in Ontario (2026): What to Inspect, the Restain Cycle and What It Costs, Insurance and Lenders, and Finding a Log Inspector

The Numbers

October 2026. Restoration prices are quoted plus HST by the companies. The turnkey line is there so you can see what replacing the house would cost; it is not what an old one is worth.

Walk the Outside First. Logs Fail From the Weather Side.

Water does the damage, and water comes from the sky and splashes up off the ground. So start at the corners, the bottom courses and the south and west walls, where the sun and the driving rain are worst. Bring a flashlight, a pocket knife or an awl, and some patience.

• Log ends at the corners. End grain soaks up water like a straw. Dark, soft or crumbly ends, or ends sticking well past the roof overhang, are the first place rot starts.
• Checks facing up. Every log cracks as it dries; that is normal. A check on the top side of a log that faces the weather holds water, and that is where rot gets in. Probe the bottom of the crack.
• The bottom two or three courses. Splash from the roof and the ground soaks them. Look for soft wood, stain worn off, and soil or decking that sits right against the logs.
• Roof overhangs and gutters. Short overhangs on a log house are a maintenance bill on a timer. Check where the downspouts empty.
• Window and door sills, and anywhere a deck ledger is fastened to the logs.
• The finish. Faded, flaking or bare grey wood means the restain is overdue. If the stain comes off on your thumb, assume the price above.

Push the knife in. Sound wood fights you. Rotten wood lets the blade sink like it is going into a block of cheddar. One or two soft spots on an end are a repair; soft bottom courses along a whole wall are a major job and a reason to renegotiate or walk.

Settling, Chinking and Carpenter Ants

Log walls shrink and settle for years as the wood dries, and the house has to be built to let them. The log homes page explains the settling in detail; when you are buying, you are looking for signs that somebody fought it.

• Settling space over windows and doors. There should be a gap above the frames that lets the logs come down without crushing them. Windows that stick, cracked glass, or frames bowing in the middle say the gap ran out.
• Adjustable posts. Posts holding up a roof or a loft often have screw jacks to be let down as the walls settle. Ask whether they have been adjusted and when.
• Interior partitions and stairs built tight to the log walls without a slip joint. Drywall cracks and doors that bind upstairs are the clue.
• Chinking and caulking. Cracked, pulled-away or missing chinking lets air and water in. You can feel draughts along the joints on a cold windy day.
• Carpenter ants. Little piles of coarse sawdust (frass) below a log, or ants indoors in early spring, mean they are nesting in wet wood somewhere. The ants are the symptom; the wet wood is the problem.

What a Log House Costs to Keep

A BC builder’s rule is restain every 4 to 5 years and wash every spring. On a 1,500 to 2,500 sq ft house at $20,000 to $30,000 a restain, that is $20,000 every 5 years, or $4,000 a year, at the low end, and $30,000 every 4 years, or $7,500 a year, at the high end. Over 20 years that is 4 restains at $20,000, $80,000, to 5 at $30,000, $150,000. Those are our arithmetic on the published prices, and they assume nothing else goes wrong.

Use it when you bid. If the finish is gone and the logs need blasting, the Ottawa-area price is $27,500 to $50,000 plus HST, and that is a fair thing to take off an offer, with a written quote in hand to back it up.

1. Ask the seller when it was last stained, with what, and by whom. Ask for the invoice. Products do not always play nicely over each other.
2. Get a restoration quote before you waive conditions, on the same written scope from two or three companies.
3. Plan an addition or a big renovation with a designer who knows logs. Log construction is Section 9.38 of the 2024 Ontario Building Code (it was 9.37 in the 2012 Code; same section, renumbered). It does not mean every log job needs an “alternative solution”, but big spans, tall walls, settling details and heavy roof loads go to an engineer. The renovations section covers permits and planning in general.

Insurers, Lenders and the Log Inspector

Some insurers and lenders treat log houses differently from ordinary frame houses, and their rules change. We are not going to guess at them for you. Ask your insurer and your lender, in writing, before you waive the financing and insurance conditions: will you insure or lend on this house, on what terms, and do you need a specialist inspection?

A general home inspector will look at the roof, the mechanical and the electrical, but log walls are their own trade. We found no published Ontario price for a log home inspection. For scale only, a BC inspector charges from $450 added to a home inspection and $650 standalone; that is a BC figure. Ask any inspector how many log houses they have inspected, and whether they will probe the logs or only look at them.

If you are thinking about building new instead, the log home designs page and the kit vs finished house page show what a log kit costs against a finished log house. The whole family of systems is in the home building systems guide.
