Carpet to Plank Flooring in Garden Grove

A Garden Grove home with old carpet through the hallway and living room. In August 2026 we pulled the carpet and pad, prepped the subfloor and installed wood-look plank flooring.

Before

Under the carpet, the hallway subfloor was covered in old adhesive and tack strip. That has to be scraped and leveled before any floating floor goes down, or the planks will click and flex.

Installation

Planks laid in a staggered pattern through the living room and hallway, cut in place with a plank cutter to keep dust down.

Why the subfloor decides the floor

Under the carpet the hallway was covered in old adhesive and tack strip. Both have to come off, and the slab underneath has to be flat, before a floating floor goes down. This is not a finish detail. A plank floor laid over a subfloor that is not flat will click underfoot where it bridges a low spot, and over time the joints work against each other until they separate.

The flatness a given floor needs comes from the flooring manufacturer’s own instructions rather than from the installer, and it varies by product. What does not vary is who carries the risk when it is ignored: most manufacturers void the warranty for installation over an out-of-tolerance subfloor. Scraping, patching and grinding is the least visible part of a flooring job and the part that decides whether the floor is still quiet in five years.

Floating, glue-down or nail-down

Three ways to attach a floor, and the right one depends on the subfloor more than on the product.

• Floating. Planks lock to each other rather than to the slab, over a thin underlayment. Fastest to install, tolerates minor slab movement, and the floor can be lifted later. Needs an expansion gap at every wall and a flat subfloor to stay quiet. This is what went down in Garden Grove.
• Glue-down. Planks bonded directly to the slab. Quieter and more solid underfoot, better over radiant heat, and the usual choice for wide planks that want to move. Slower, messier, and it makes the next replacement a bigger job.
• Nail-down. Only over a wood subfloor, which rules it out on the slab-on-grade construction common across Southern California. Standard for solid hardwood where there is a crawlspace or a raised floor.

LVP, laminate and engineered wood

Wood-look flooring is three different products, and the names get used loosely, which is how people end up disappointed.

• Luxury vinyl plank (LVP). Entirely synthetic and waterproof through the full thickness. The right answer in kitchens, bathrooms, laundries, and anywhere on a slab where moisture is a question.
• Laminate. A printed layer over a fibreboard core. Hard-wearing and inexpensive, but the core swells if water sits on a seam. Fine in bedrooms and hallways, a gamble near plumbing.
• Engineered wood. A real wood wear layer over plywood. It looks like hardwood because the surface is hardwood, and it is far more stable than solid wood over a slab. Depending on the thickness of the wear layer it can be sanded and refinished once or twice.

For this house the hallway and living room ran together, so using one product across both was the decision that mattered most — a transition strip in the middle of an open run reads as a mistake even when the floors either side are good.

What plank flooring needs underneath

Replacing carpet with plank flooring does not normally need a permit, but three things decide whether the finished floor is flat and quiet: the subfloor is flattened to the manufacturer tolerance, moisture is measured and a barrier used where the floor sits over a slab, and transitions and baseboards are planned before the first plank is laid. See flooring for the materials we install and Orange County for where we work.

Questions homeowners ask about replacing carpet with plank

Can plank flooring go straight over old carpet, pad or tile?

Not over carpet or pad — both come out, along with the tack strip. Over existing tile it is sometimes possible, but only if the tile is sound, bonded and flat, and it raises the finished floor height enough to affect doors, appliances and thresholds. On this job everything came out and the slab was prepped bare.

Why does a new floor click or feel hollow?

Almost always the subfloor rather than the planks. Where a floating floor bridges a low spot it flexes, and the locking joint makes a noise. It is why the scraping and levelling matters more than the product choice, and why it is worth asking any flooring bid exactly what it includes for subfloor preparation.

Do the baseboards have to come off?

Not necessarily. A floating floor needs an expansion gap around the perimeter, which is either hidden by removing and refitting the base, or covered with shoe moulding against the existing base. Removing and refitting looks cleaner; shoe moulding is quicker and cheaper. Both are legitimate. What is not legitimate is closing the gap up tight, which is what makes a floating floor buckle.

Is LVP actually waterproof?

The plank is. The assembly is not automatically. Water that gets through a seam and sits on the subfloor still causes problems, and a floating floor can trap it. Waterproof means the plank will not swell, not that a leak underneath it is harmless.

How long does a job like this take?

The installation itself is usually quick — a hallway and living room is normally a matter of days. What extends it is subfloor preparation: scraping old adhesive, patching, levelling, and letting patching compound cure before planks go down. A bid that allows no time for that is not planning to do it.

What should a flooring proposal list?

Removal and disposal of the existing floor, subfloor preparation including levelling, the product and its thickness, the underlayment, transitions and thresholds, and how the perimeter gap is finished. Our flooring page covers the materials we install across Los Angeles and Orange County.
