Re-side or repair a New Brunswick cottage?

For most NB cottages showing widespread siding deterioration, a full re-side is the smarter investment — but targeted repairs make sense when damage is isolated to less than 20-25% of the exterior surface.

The decision comes down to three things: how much of the existing siding is compromised, what's underneath it, and how long you plan to keep the cottage. Patching failing siding on a cottage that sees seasonal temperature swings, coastal humidity, and years of deferred maintenance is often a short-term fix that delays the inevitable. That said, if your cottage has solid original cedar shingles or older wood siding with only a few damaged sections, a skilled carpenter can do targeted repairs that buy you another decade at a fraction of the cost.

The honest reality with NB cottages is that the siding conversation almost always leads to a bigger one. When contractors start pulling off old siding — especially on cottages built before the 1990s — they regularly find rotted sheathing, missing or degraded housewrap, inadequate insulation, and sometimes structural surprises around windows and corners. Budget a 20-25% contingency on any cottage re-side for exactly this reason. A job that quotes at $15,000 can easily run $18,000-$20,000 once the wall assembly is exposed.

Repair vs. Replace: The Cost Comparison

Targeted siding repairs on a typical NB cottage run $1,500-$6,000 depending on the number of sections involved, access difficulty, and whether sheathing repairs are needed underneath. A full re-side on a modest 800-1,200 sq ft cottage exterior costs $8,000-$18,000 for vinyl, $12,000-$22,000 for LP SmartSide engineered wood, or $14,000-$25,000 for fibre cement (HardiePlank). Those ranges reflect the full job — removal of old siding, housewrap, any sheathing repairs, new siding, trim, and caulking.

If your repair quotes are coming in above $5,000-$6,000, get a full re-side quote for comparison. The gap often narrows enough that the full replacement pencils out — especially when you factor in the new warranty, improved energy performance, and not having to revisit the project in three to five years.

NB-Specific Considerations for Cottages

Maritime conditions are brutal on cottage siding for a specific reason: cottages sit unheated through NB winters, meaning the wall assembly goes through the full freeze-thaw cycle without the moderating effect of interior heat. This accelerates moisture infiltration behind siding, paint failure, and wood rot at a faster rate than a year-round home. Cottages near the Bay of Fundy, Northumberland Strait, or any lake or river exposure face additional wind-driven rain and humidity that shortens siding lifespan further.

For coastal or lakefront NB cottages, fibre cement or engineered wood siding outperforms vinyl over the long term. Vinyl can become brittle in extreme cold and is more vulnerable to impact damage from wind-driven debris. HardiePlank and LP SmartSide both handle NB's humidity swings and freeze-thaw cycles well, hold paint longer, and resist rot and insects. If budget is the priority, premium vinyl (at least .044" thickness) is still a solid choice — just ensure it's installed with proper expansion gaps, because cottages see wider temperature swings than year-round homes and vinyl needs room to move.

Practical Steps Before You Decide

Start by probing the siding and sheathing around windows, corners, at the base of walls, and anywhere you see paint failure or discolouration — these are the highest-risk zones for rot. A flat-head screwdriver pushed firmly into wood siding should meet solid resistance; if it sinks in, you have rot. Check the condition of the housewrap or building paper underneath any loose sections. Look at the caulking around every window and door frame — failed caulking is often the entry point for the moisture that causes the rot you're seeing.

Get two or three quotes from contractors experienced with cottage work specifically. Cottage re-sides have different logistics than year-round homes — access, seasonal scheduling, and the likelihood of finding hidden issues all affect pricing. Schedule exterior work for May through September in NB; caulking and siding adhesives need consistent temperatures above 10°C to seal properly, and you don't want a half-finished cottage exterior heading into October.
