Can I install laminate over existing vinyl flooring in my Vancouver kitchen without removing it?

Yes, you can install laminate over existing vinyl flooring in most cases, but there are several important conditions that must be met — and in a Vancouver kitchen, moisture management deserves extra attention. Installing over existing vinyl avoids the cost and mess of removal, and it is a common approach in Metro Vancouver renovations. However, cutting corners on preparation leads to problems that are expensive to fix after the laminate is down.

The existing vinyl must be in good condition. The vinyl needs to be firmly bonded to the subfloor with no loose edges, bubbles, lifting seams, or curling corners. If the vinyl is peeling up, it cannot serve as a stable base for your new laminate. Any raised seams, bumps, or damaged areas will telegraph through the laminate and create visible imperfections and premature wear points. Walk the entire kitchen floor and press firmly on all edges and seams — anything that moves or feels hollow needs attention. Small areas of damage can be patched with floor leveling compound, but if more than 10-15% of the vinyl is compromised, removal is the better path.

The subfloor must be flat within tolerances. Laminate manufacturers require the subfloor to be flat within 3/16 inch over 10 feet (some require 1/8 inch). Place a long straightedge across the vinyl in multiple directions and check for dips and humps. Old vinyl in Vancouver kitchens — particularly in homes from the 1960s through 1980s — often sits over plywood that has developed waves, soft spots, or unevenness from decades of moisture exposure. If the floor is not flat enough, self-leveling compound can be applied over the vinyl in most cases, adding $2 to $5 per square foot to the project.

The critical caution for pre-1990 vinyl: test for asbestos before doing anything. Vinyl floor tiles manufactured before 1990 — especially 9x9-inch tiles — and the black mastic adhesive used to install them frequently contain asbestos. Sheet vinyl from the same era may also contain asbestos in the backing material. If your Vancouver home was built before 1990 and has original vinyl flooring, do not sand, scrape, score, or disturb it without professional asbestos testing first. If asbestos is confirmed, the safest approach is actually to encapsulate it by installing the new laminate directly over top (leaving the asbestos undisturbed), which is an accepted method under BC regulations. However, this must be done with full awareness of what is beneath — document it for future owners. Professional testing costs $200 to $500 and is legally required in BC before removing suspected asbestos-containing materials.

For a Vancouver kitchen specifically, consider the moisture factor. Kitchens generate moisture from cooking, dishwashers, sink splashes, and cleaning. Laminate's HDF core is not waterproof, and installing it in a kitchen — even over vinyl — requires choosing a water-resistant laminate with wax-sealed edges and maintaining diligent spill cleanup. Honestly, if you are already going to the effort of new kitchen flooring, SPC vinyl plank at $5 to $12 per square foot installed is a smarter choice for a kitchen because it is 100% waterproof and can also be installed directly over existing vinyl under the same conditions.

When installing laminate over vinyl, use a quality foam underlayment with an integrated vapour barrier between the vinyl and the new laminate. Do not skip the underlayment — it provides cushion, sound dampening, and moisture protection. Leave 1/4-inch expansion gaps around all walls, cabinets, and islands, and use transition strips at doorways. The combined height of the existing vinyl plus underlayment plus laminate will raise your floor level by approximately 3/8 to 1/2 inch, so check that doors, appliances, and cabinet toe kicks will clear the new height before you begin.

For a kitchen installation — whether laminate or SPC over existing vinyl — professional installation ensures proper transitions around cabinets, islands, and appliances. Vancouver Floor Installers can match you with experienced local contractors for a free estimate.
