Underlayment and Moisture Barrier in San Francisco, CA

Underlayment is invisible once the floor is down and it decides how that floor sounds, feels and lasts. It levels minor subfloor variation, deadens sound between storeys, and in the case of a moisture barrier it stops vapour rising out of a concrete slab into the flooring above.

Concrete passes moisture continuously, including slabs that read completely dry to the touch. Installing over a slab without a barrier is how floors cup, adhesive fails and laminate swells from underneath months after a faultless installation.

Hardline Surface Co. tests and specifies across San Francisco, CA before anything is laid.

One thing worth knowing: many click-lock floors arrive with a pad already attached to the plank. Adding a second underlayment beneath that is too much cushion, and the joints fail because the planks flex more than the locking system tolerates. More is not better here.

Underlayment And Moisture Barrier FAQs

Frequently asked questions about Underlayment and Moisture Barrier

Questions we hear most often about Underlayment and Moisture Barrier in San Francisco, CA.

Talk to a real person
What wear layer do I need for luxury vinyl plank?
12 mil for bedrooms and low traffic, 20 mil for pets, children and entry halls. Total plank thickness is not the number that matters, and a thick plank with a thin wear layer scratches within a year.
Porcelain or ceramic, which should I choose?
Porcelain absorbs under 0.5% water and suits wet areas, exteriors and freeze-prone spaces. Ceramic costs less and is perfectly good for dry indoor floors, walls and backsplashes.
Why does my tile quote include floor preparation?
Because tile cracks on an uneven subfloor, and large format needs flatter than most people expect. A quote without preparation is not cheaper, it is incomplete, and the cost arrives later as failed grout and lifted corners.
Do I need underlayment over a concrete slab?
You need a moisture barrier. Concrete passes vapour continuously even when it reads completely dry, and skipping it is how floors cup and adhesive fails months after a perfect installation.
What is the best floor for a laundry room?
Sheet vinyl. It arrives in one continuous piece with no seams, and seams are exactly where water reaches the subfloor when an appliance fails.
