How long does laminate flooring last in a New Brunswick home?

Quality laminate flooring typically lasts 15-25 years in a New Brunswick home, though actual lifespan depends heavily on the product quality, installation conditions, and how well you manage NB's seasonal humidity swings. Budget laminate may show wear in as little as 7-10 years, while premium AC5-rated products in well-maintained environments can approach 30 years.

The single biggest factor affecting laminate lifespan in NB is moisture management. Our Maritime climate creates a 30-50% relative humidity swing between the dry heating season (20-30% RH from October to April) and the humid summer months (potentially above 65% RH from June to September). This annual cycle repeatedly stresses the HDF core and click-lock joints of laminate flooring. Over years of expansion and contraction, joints can loosen, edges can lift, and the surface layer can begin to separate from the core — especially in homes without humidity control.

NB homeowners who run a humidifier in winter (keeping RH above 35%) and a dehumidifier or AC in summer (keeping RH below 55%) will see significantly longer life from their laminate floors. Without humidity management, expect to lose 5-10 years from the product's rated lifespan, particularly in coastal communities like Saint John, Shediac, and Bathurst where ambient humidity runs higher year-round.

Product quality matters enormously. The AC (Abrasion Class) rating tells you about wear resistance: AC3 is rated for residential use, AC4 for heavy residential and light commercial, and AC5 for heavy commercial. For a busy NB household with kids, pets, and winter boot traffic, AC4 is the minimum — it resists scratches, dents, and wear far better than AC3. The wear layer thickness also varies: budget laminate may have a wear layer as thin as 6 mil, while premium products run 12-20 mil. That extra thickness directly translates to years of life.

The underlayment and installation quality also affect longevity. Proper underlayment with an integrated vapour barrier protects the HDF core from subfloor moisture — critical in NB homes, especially those with crawl spaces or concrete slabs. Correct expansion gaps (8-12mm around all perimeters) prevent buckling during summer humidity spikes. Poor installation that skimps on these details can cut a floor's life in half.

One important limitation: laminate cannot be refinished. Unlike hardwood, which can be sanded and refinished 3-5 times over a 50-100 year lifespan, laminate is a one-life product. Once the wear layer is gone or the surface is damaged beyond cosmetic repair, the entire floor must be replaced. At $4-$8/sq ft fully installed in NB, replacing a 1,000 sq ft laminate floor runs $4,000-$8,000 — a significant cost every 15-25 years compared to hardwood refinishing at $3-$6/sq ft.

For maximum laminate lifespan in NB, choose AC4 or AC5 rated products, install with quality vapour-barrier underlayment, maintain indoor humidity between 35-55% year-round, use entry mats to catch winter grit and salt, and clean with a damp (not wet) mop.
