What direction should I lay hardwood planks in my New Brunswick home?

The general rule is to lay hardwood planks parallel to the longest wall or the main source of natural light in the room, but structural considerations in your NB home may override aesthetics. Getting the direction right affects how your floor looks, how it performs structurally, and how it handles New Brunswick's significant seasonal humidity swings.

Structural orientation comes first. For nail-down or staple-down hardwood installations over a wood subfloor — the most common method in NB homes — the planks should run perpendicular to the floor joists. This distributes the load across multiple joists and creates a stronger, more stable floor assembly. In most NB homes, floor joists run the short direction of the house (side to side), which means hardwood planks typically run the long direction (front to back). If you are unsure which way your joists run, check the basement or crawl space, or look for the nail lines in your existing subfloor — the nails penetrate the joists and reveal their direction.

If you have a plywood subfloor that is at least 3/4 inch thick and in good condition, you have more flexibility — the plywood provides enough structural support that you can run planks in either direction. This is also true for engineered hardwood installed as a floating floor, which does not fasten to the subfloor at all.

Once structural needs are met, consider aesthetics. Running planks parallel to the longest dimension of a room makes the space feel larger and creates a natural visual flow. In narrow hallways, planks running lengthwise make the hallway feel less cramped. For rooms with a strong natural light source — a large window or sliding door — running planks toward or away from the light minimizes the visibility of seams and surface imperfections. Light hitting planks from the side (perpendicular to the length) highlights every joint and any slight height differences between boards.

In NB open-concept homes, which have become increasingly common in newer builds and renovations, maintaining a consistent plank direction throughout the main living area creates a cohesive, spacious feel. Choose the direction based on the dominant visual line — usually front door to back wall or toward the largest window grouping. If your open-concept space has a hallway connecting to bedrooms, continuing the same direction into the hallway and bedrooms creates seamless flow.

A few NB-specific considerations. In older New Brunswick homes — particularly pre-1970s construction common in Fredericton, Moncton, and Saint John — the original subfloor may be diagonal board sheathing rather than plywood. Diagonal subfloors actually allow hardwood to run in any direction, which gives you full aesthetic freedom. However, these old board subfloors often need a 3/8-inch plywood overlay ($1.50–$3.00 per square foot) before hardwood installation to create a flat, stable nailing surface.

For homes on crawl spaces or pier foundations — still common in rural NB and older neighbourhoods — the subfloor may have subtle unevenness from frost heave and seasonal movement. Running planks perpendicular to the joists helps bridge minor imperfections and creates a stiffer floor assembly that resists deflection.

Avoid running planks parallel to a long, prominent wall if that wall is not perfectly straight — the gap between the first row and the wall will vary visibly and look like a poor installation. In older NB homes where walls are rarely perfectly square, snap a chalk line parallel to the room's centre line and work outward in both directions, trimming the first and last rows to split any irregularity evenly. This is one of the reasons professional installation ($3–$6 per square foot for labour) is worth considering for hardwood — experienced installers know how to handle the quirks of New Brunswick's older housing stock.
