Specialty Wood, on Request

From pine and cedar to panelling and MDF, our interior lumber covers the finishing materials that shape a cottage's character inside – trim, ceilings, closets, and feature walls. Each species is chosen for how it performs indoors, holding up to humidity swings, taking finish evenly, and standing up to seasonal use.

What We Carry

  • Close-up view of wooden planks on a deck or flooring.

    Pine

    Straight-grained and easy to work with, pine dries with minimal warping. A reliable, budget-friendly choice for trim, panelling, and millwork, especially well suited to cottage interiors like ceilings, closets, and other conditioned interior spaces.

  • Close-up of wooden outdoor deck with visible wood grain and knots.

    Cedar

    Cedar naturally resists rot, insects, and moisture, making it reliable for exposed exterior work like siding, soffits, and dock structures. Lightweight, easy to work with, and holds paint or stain well, or can weather to a natural silver-grey patina. We stock red and white cedar.

    Panelling

    Panelling, including tongue and groove, shiplap, and beadboard, adds warmth, texture, and architectural character to any wall or ceiling. It's also one of the easiest interior finishes to transport and install on boat-access and remote sites, where materials often arrive by water or ice road.

  • Close-up of white and beige window sills with metal tracks, viewed from inside a room.

    MDF

    MDF offers a smooth, grain-free surface that takes paint, veneer, or laminate cleanly, at a lower cost than plywood. Best suited to conditioned interiors, not cottages left unheated over winter, since it swells with humidity exposure.

    Specialty & Exotic Wood

    From core species like Douglas fir, white pine, and red or white cedar, to true exotics like mahogany and teak, we source specialty and imported wood for projects that call for something the standard lineup can't offer. Ask us about what's possible for your build.

Frequently Asked Questions

  • It really comes down to look, budget, and where the wood is going. Pine is affordable, widely available, and easy to work with, which makes it a reliable choice for trim, panelling, and ceilings. Cedar costs more but brings natural warmth, a pleasant aroma, and better resistance to moisture, so it shines in feature walls and damp-prone spaces. We stock both and can help you match the species to the room and the finish you are after.

  • oth are popular panelling styles, and the difference is in how the boards join. Shiplap boards overlap with a small, even reveal, or gap, between them, giving that clean lined look you see in modern and farmhouse interiors. Tongue-and-groove boards interlock, one edge slotting into the next, for a tighter, more seamless surface. The choice is mostly aesthetic, and we carry both for walls and ceilings.

  • Pine and cedar are the two go-to choices for interior walls and ceilings, and both come in tongue-and-groove, shiplap, and beadboard profiles. Pine offers a clean, budget-friendly look that takes stain or paint well, while cedar adds warmth, character, and natural moisture resistance. The best pick depends on the style you want and your budget. Bring us your project and we will help you match species and profile.
