We get a lot of spring moisture in the basement — would glue-down vinyl handle that better than click-lock?

Glue-down vinyl can actually be more vulnerable to moisture problems than click-lock in a basement setting — which surprises a lot of homeowners. The adhesive bond can fail when moisture migrates up through a concrete slab, causing tiles or planks to lift, bubble, or shift over time.

Click-lock LVP (luxury vinyl plank) with a rigid core — specifically SPC (Stone Plastic Composite) — is generally the better choice for Ottawa basements with spring moisture concerns. SPC flooring is 100% waterproof, dimensionally stable, and floats above the slab rather than bonding to it. This means minor moisture fluctuations beneath the floor don't compromise the installation. The floating assembly also allows the floor to move slightly with seasonal humidity changes, which is very common in Ottawa's climate.

That said, no flooring product solves an underlying moisture problem. Before any installation, your contractor should perform a calcium chloride moisture test or a relative humidity in-slab test on your concrete. If moisture vapor emission rates are too high, even the best LVP will eventually show problems. A 6-mil poly vapour barrier (or a premium underlayment with a built-in moisture barrier) is standard practice on Ottawa basement slabs, and in some cases a drainage membrane may be recommended first.

For Ottawa basements specifically, spring moisture is often tied to snowmelt and ground saturation — a very real seasonal issue here. If you're seeing actual water intrusion (not just humidity), that needs to be addressed before any flooring goes down, regardless of product type.
