LVP vs. Hardwood for a South Jersey Basement

We get asked this question more than almost any other flooring question in South Jersey: should I put hardwood in my finished basement, or should I do luxury vinyl plank? Our honest answer, for almost every basement we have seen in Sicklerville, Williamstown, Blackwood, Turnersville, Washington Township, and Glassboro: do LVP. Here is why, and here is when it is OK to break that rule.

The short version

• South Jersey basements are humid. Many have a water history.
• Solid hardwood swells, cups, and crowns when humidity goes above 65 percent for any length of time.
• LVP is waterproof, dimensionally stable, and looks legitimately like wood.
• LVP costs $4 to $8 per square foot installed. Solid hardwood runs $9 to $14.

Why South Jersey basements are different

The water table in Gloucester and Camden County sits higher than in a lot of the country. Most basements in the area have at least one of these: a sump pump, perimeter drainage, a French drain, a dehumidifier running 9 months out of the year, or a history of taking water during a heavy rain.

Even basements that "never get water" usually sit at 55 to 70 percent relative humidity in the summer. Hardwood manufacturers spec their flooring for 35 to 55 percent. Run it above 65 percent for a season and the boards will cup. Run it through one wet event and the boards are done.

What LVP solves

Waterproof core

The plank is built around a rigid SPC (stone-plastic composite) or WPC (wood-plastic composite) core. Water on top, water from below, the core does not move. We have pulled up LVP from a basement that took 2 inches of standing water during a Nor'easter, dried it overnight, and re-laid the same planks.

Dimensional stability

LVP planks expand and contract maybe 1/32 of an inch across a full board with temperature swings. Hardwood can move 1/4 of an inch. That difference is the difference between tight seams forever and visible gaps in February.

Looks the part

LVP from 2018 looked plastic. LVP in 2026 has embossed grain, beveled edges that line up tile-style, plank widths up to 9 inches, and color matching that holds up at eye level. Most clients we install for cannot tell their installed LVP from real engineered hardwood from a standing position.

When hardwood IS the right call

We will not pretend hardwood never makes sense. Here is when it does:

• Above-grade installs only. Main floors, second floors, finished attic spaces. Not basements.
• You are doing a refinish, not a new install. If you already have hardwood, refinishing it is almost always cheaper than ripping it out for LVP. We do refinishing.
• The house is a high-end resale play. Some Camden and Gloucester County price tiers (think Mullica Hill, Mantua) still see a small resale bump from real hardwood on main floors. Not so much in basements.

What about engineered hardwood?

Engineered hardwood is real wood on top, plywood underneath. It handles humidity better than solid wood, but it is still wood. We have seen engineered hardwood cup in South Jersey basements at 70 percent humidity even with a dehumidifier running. If you are dead set on a wood-look basement floor, engineered is one notch better than solid. But LVP is two notches better than engineered.

The install process for basement LVP

The thing that kills basement floor installs is not the floor. It is the subfloor.

1. Moisture testing

Before we lay anything we run a calcium chloride test or use a Tramex meter on the concrete slab. If the slab is reading above 75 percent relative humidity, we put down a moisture barrier or recommend addressing the source (drainage, dehumidifier) first.

2. Subfloor levelling

Most basement slabs in our area are off-level by 1/4 to 3/4 of an inch across a single room. We grind high spots and float low spots with self-levelling compound before any plank goes down. Skip this step and the floor will click and pop forever.

3. Underlayment

Most click-lock LVP comes with an attached underlayment pad. Over concrete in a basement, we add a 6-mil poly vapor barrier under it. Belt and suspenders.

4. Install

Click-lock LVP installs as a floating floor. We leave a 1/4 inch expansion gap at every wall, run the planks perpendicular to the longest wall, and finish with shoe molding (which we paint to match the baseboard).

Costs we typically quote in South Jersey

• LVP, material plus install, 600 sq ft basement: $3,500 to $5,500.
• Self-leveller and moisture prep, if needed: $500 to $1,500.
• Removal of existing carpet or laminate: $300 to $800.
• Shoe molding paint and reinstall: $200 to $400.
