What is the average cost to install luxury vinyl plank flooring throughout a finished basement in New Brunswick?

Installing luxury vinyl plank (LVP) flooring throughout a finished basement in New Brunswick typically costs between $4 and $8 per square foot installed, making it the most popular basement flooring choice in the province. For an average 800-square-foot basement, that works out to roughly $3,200 to $6,400 for materials and labour combined.

The price range depends heavily on the quality of LVP you choose. Budget-grade LVP (4mm thick, no attached underlayment) sits at the lower end around $4 per square foot installed, while premium options with a rigid SPC core, integrated cork backing, and a thicker wear layer push closer to $8 per square foot. For a New Brunswick basement, you want a minimum 5mm thickness with a rigid core — thinner products flex on slightly uneven concrete slabs and the click joints can separate over time.

What most homeowners overlook is the cost of subfloor preparation underneath the LVP. In New Brunswick's Maritime climate, concrete slabs wick moisture constantly due to high water tables and seasonal groundwater fluctuations. Installing LVP directly on bare concrete — even with the basic underlayment pad — risks trapped moisture, musty odours, and eventual adhesive breakdown. A Dricore subfloor panel system at $3 to $5 per square foot adds an air gap between the concrete and your flooring, which is the single best investment you can make for basement flooring longevity in NB. With Dricore underneath, your total flooring cost rises to $7 to $13 per square foot, or roughly $5,600 to $10,400 for an 800-square-foot basement.

Before any flooring goes down, you should perform a calcium chloride moisture test or tape a piece of plastic sheeting to the slab for 48 hours. If moisture accumulates underneath, you need to address that first with a vapour barrier, Dricore panels, or potentially interior waterproofing. In areas like Saint John with heavy clay soils, or coastal communities like Shediac with naturally high water tables, moisture testing is absolutely essential.

A few practical tips for NB homeowners. First, purchase 10% extra material beyond your measured square footage to account for cuts, waste, and future repairs — LVP dye lots vary, and matching later is nearly impossible. Second, let the LVP acclimate in the basement for 48 hours before installation so it adjusts to the cooler below-grade temperature. Third, choose a product rated for below-grade installation — not all LVP is rated for basements despite being waterproof on the surface.

Installing LVP on a prepared subfloor is one of the few basement projects a handy homeowner can tackle as a DIY job, potentially saving $1.50 to $3.00 per square foot in labour. However, if your concrete slab is significantly uneven (more than 3mm variation over 10 feet), you will need a self-levelling compound applied first, which is best left to a professional. Get at least three quotes from local contractors — NB pricing varies 30 to 40 percent between companies for the same scope of work.
