How do I plan a NB floor transition into the dining room?

Plan your kitchen-to-dining room floor transition by choosing the right transition strip type, matching your subfloor heights, and selecting materials that handle New Brunswick's humidity swings without buckling or gapping.

A floor transition is one of those details that looks simple but causes real headaches if done wrong — especially in NB homes where seasonal humidity changes cause flooring materials to expand and contract significantly. Getting it right means understanding your specific flooring combination, your subfloor situation, and how NB's climate will affect both materials year-round.

Choosing the Right Transition Type

The transition strip you need depends on what's on each side of the doorway. The four most common scenarios in NB kitchens are:

Same-height floors (e.g., LVP meeting hardwood at the same level) use a T-molding — the most common and cleanest-looking option. Height-difference transitions (e.g., tile meeting hardwood where one sits higher) use a reducer strip, which slopes from the higher floor down to the lower one. If your kitchen flooring ends at a wall or cabinet base with no adjoining room floor, a end cap/threshold finishes the edge cleanly. Carpet to hard flooring uses a carpet bar with a tack strip underneath.

Most transition strips are available in wood, aluminum, or vinyl — match your flooring material as closely as possible for a cohesive look.

Subfloor Height Is Everything

Before you pick a strip, check whether your kitchen and dining room subfloors are at the same height. In many NB homes built in the 1960s-1990s, kitchens were tiled or had vinyl over a plywood underlayment, while dining rooms had hardwood directly on the subfloor — creating a height mismatch of 6-12mm. Adding LVP in the kitchen (typically 6-8mm thick) over that old underlayment can make the height difference worse.

If you have a significant height difference, a self-levelling compound or feathering compound applied to the lower subfloor before installation is the right fix — not a thicker transition strip. A transition strip can only bridge about 10-12mm of height difference before it becomes a tripping hazard.

NB Climate Considerations

This is where NB kitchens differ from the rest of Canada. Your flooring will shrink noticeably in winter when forced-air heating drops indoor humidity to 15-25%, and expand in summer when Maritime humidity climbs. LVP and hardwood need expansion gaps (typically 6-10mm) at all walls and transitions — the transition strip covers this gap while allowing movement underneath.

Never glue or nail flooring tight to the transition strip. The strip should float over the gap, fastened only to the subfloor through its track. If the flooring is locked in place at the transition, it has nowhere to go when it expands — and it will buckle.

Practical Tips

Start by measuring the height of both finished floors before buying any transition hardware. Bring a sample of both flooring materials to your flooring supplier — most can match transition strips closely. If you're installing LVP in the kitchen yourself, leave the transition installation until both rooms are fully floored and you can confirm the final heights. For doorways wider than 900mm, use a longer transition strip cut to fit rather than two shorter pieces end-to-end.

When to hire a pro: The transition installation itself is manageable DIY if you're comfortable with basic tools. However, if the subfloor height difference is more than 12mm, or if you're dealing with an uneven subfloor (common in older NB homes), a flooring professional should assess whether levelling compound or subfloor shimming is needed first — getting that wrong affects the entire floor, not just the transition.
