When the pad is the problem: old carpet padding in Rosedale

What the pad is doing down there

The pad takes the impact of every step so the carpet backing doesn't have to. It's a big part of why carpet feels soft, and it helps the carpet wear more slowly. When the pad breaks down, the carpet above it starts taking that beating, and you can see it in the traffic lanes.

Pads age on their own, too. Older foam and rubber pads can dry out and crumble even in rooms that barely get used, so a spare bedroom isn't safe just because nobody walks in it.

A crunch underfoot

A pad that's falling apart often announces itself with sound. You may hear a slight crunch or crinkle as you walk, or feel a gritty, uneven surface through the carpet. Sometimes yellowed or brownish crumbs show up along the wall or at a floor vent.

Cleaning won't put a crumbling pad back together, and it won't make the room feel softer. If most of the house crunches, the pad has reached the end of its life, and no amount of vacuuming will change the way the floor feels.

Lanes that feel thin

Walk from the doorway to the sofa, then across a corner nobody uses. If the path feels hard and flat and the corner still feels plush, the pad in the traffic lane has probably compressed. The carpet over it tends to mat down faster, too, because nothing underneath is cushioning it.

Cleaning can pull soil out of those lanes and help the pile stand up for a while. It can't give the pad its thickness back. If the lane feels like carpet laid over plywood, that feeling will still be there after the cleaning.

Ripples and humps

Ripples usually mean the carpet has come loose from the tack strip or wasn't stretched tight enough when it went in. Dragging heavy furniture, a pad that's too soft or too thick and big swings in humidity can all make it worse.

Some carpets relax slightly while they're damp after cleaning and settle again as they dry. But a ripple that was there before the cleaning will be there after it. The fix is a re-stretch with a power stretcher, and that's a job for a carpet installer. Ripples also wear faster than the flat carpet around them, because the vacuum and every footstep hit the raised fold first.

A smell that keeps coming back

This one is the most frustrating. The carpet gets cleaned, the room smells better for a while, and then the old odor returns, often on humid days. That pattern points below the carpet fibers: pet urine that soaked through to the pad, or an old spill that reached the subfloor.

Pad soaks up liquid and holds it, and surface cleaning, even thorough hot water extraction, isn't built to flush out a pad underneath. When urine has soaked the pad or subfloor, replacing that section of pad and sealing the subfloor is usually the real fix. If the carpet on top is in good shape, it can often be cleaned and kept.

Checking without tearing anything up

You don't need to pull back the carpet to learn something useful:

• Lift a floor register in a carpeted room. The cut edge of the carpet and pad is right there. Press the pad with a finger. It should spring back, not crumble or leave dust behind.
• Walk each room slowly in socks and note where it crunches, feels hard or feels lumpy.
• Look along the walls and around vent openings for crumbs or dust that won't vacuum away.

Leave the actual pulling back to an installer. Tack strips are sharp, and a corner lifted carelessly may not lie flat again.

Clean, patch or replace

Here's how the decision usually breaks down:

• Carpet in good shape, pad fine, just dirty: clean it.
• Carpet in good shape, pad bad in one area: have an installer replace that section of pad, then clean.
• Carpet worn and pad crumbling everywhere: put the money toward new carpet and pad instead.
