Rug pads: which kind for hardwood floors, the 80% rule in NYC apartments, and what to do with the pad when the rug is washed

Most people buy a rug pad once, cut it to fit, and never look at it again until the rug comes up for a wash or a move. That's usually when they find out it was the wrong one: a waffle pad that has crumbled into orange dust, a rubber pad that left a cloudy rectangle on the floor, or a thin gripper that does nothing for the neighbor downstairs. Here's how to pick a pad that suits the floor, what to check when the rug is out, and how the 80% carpet rule in a lot of New York apartment leases fits in.

What a pad is actually for

A pad does three jobs, and different pads are good at different ones:

• Grip. It stops the rug sliding when someone steps on the edge, and stops a runner from creeping down the hall.
• Cushion and wear. It takes the grinding of feet and furniture legs, so the rug's back isn't rubbing directly against the floor and grit. That's easier on both.
• Sound. A dense pad soaks up footsteps and dropped toys. In an apartment, this is often the reason the pad is there at all.

It also lets air under the rug, which matters on a basement slab or anywhere a spill might sit.

The main types, and where each one fits

On hardwood: avoid the pads that mark the finish

Most hardwood in NYC apartments and older houses has a polyurethane finish, and some rubber and plastic pads react with it. Plasticizers and some additives in PVC and synthetic rubber can move into the finish over months, and the result is a hazy or yellowed patch in the shape of the pad, sometimes with a waffle pattern pressed into it. Many flooring makers' care guides say to avoid plastic, adhesive-backed and “tacky” pads for this reason, and some exclude that kind of damage from their warranties.

What to look for instead: felt, felt with solid natural rubber, or a pad sold as safe for finished floors. If you don't know what your floor is or who made it (common in a rental or a prewar co-op with old parquet), felt or felt-and-natural-rubber is the safe default.

Two other floor points:

• Freshly refinished floors need to cure before a pad and rug go down. Finish makers usually say a few weeks; check the product your floor guy used. Putting the rug back the day after the last coat is how pads get stuck to floors.
• Radiant heat under the floor: thick felt insulates it. Use a thinner pad, and check the heating system's guidance if the room runs cold with the rug down.

Sizing and thickness

• Cut it a little smaller than the rug, about an inch in from each edge, so the pad doesn't show and the rug's edges slope down to the floor instead of making a ledge to trip on. Most pads cut with heavy scissors.
• Measure the rug body, not the fringe. The fringe should lie flat on the floor past the end of the pad.
• Thickness: around 1/4 inch suits most rugs and still lets doors swing over. Thicker felt helps with sound but can catch a door or a dishwasher drawer, so check clearance before you buy. A thin flatweave on a thick pad feels spongy and wrinkles more easily.
• Runners: a thin rubber or felt-and-rubber pad, trimmed the same way. A runner on bare wood is the rug most likely to slide out from under someone.

The 80% rule in New York apartments

A lot of NYC leases and co-op house rules say floors must be covered with rugs or carpet, typically 80% of each room, with kitchens, bathrooms, closets and often foyers left out. There's no citywide law; it comes from your own lease or building rules, so read the clause. Some buildings only count rugs, some ask for padding too, and some say “rugs or equally effective noise-reducing material.” In practice it usually comes up after a downstairs neighbor complains, and management may ask to inspect.

If you're covering floors for this reason, the pad matters as much as the rug. A thin flatweave on a plastic gripper doesn't do much for footsteps. A felt pad, or felt with natural rubber, under a rug that reaches close to the walls does far more. In a bedroom over someone else's living room, it's worth going thicker.

The rule also matters when a rug goes out for cleaning. A full wash means the floor is bare for about two weeks (pickup to return is normally 7–10 business days). If you've had noise complaints or your building is strict about inspections, a few things help:

• Send one big rug at a time and leave the pad down. A pad alone muffles some noise and keeps its place in the room.
• Put a spare or summer rug down while the main one is out, if you have one.
• If you've talked to the neighbor below before, a short note saying the rug is out for cleaning for two weeks tends to go over better than silence.

Washing several rugs together saves on pickup (every rug in one booking counts toward the $250 free-pickup threshold), but it leaves more floor bare at once. Weigh that against how touchy your building is.

When the rug goes out for a wash: what to do with the pad

The pad stays home. It isn't measured or priced, and the rug rolls tighter and travels better without it. Use the time it's gone:

1. Lift the pad and look at the floor. Grit and fine dust work through a rug and collect under the pad. Vacuum or dust-mop the floor before anything goes back down.
2. Check for residue. A sticky film or crumbs from an old pad usually come off with a plastic card and the cleaner your floor maker recommends. A cloudy or yellowed patch that won't wipe away is in the finish, and that's a floor refinisher's job, not a cleaning one.
3. Look at the floor color. Wood under a rug is often a different shade from the boards around it that got sun. That's the floor aging unevenly, not damage, and it usually evens out slowly once both areas get the same light.
4. Decide whether the pad goes back. Replace it if it's crumbling, flattened hard, stuck to the floor, a PVC waffle on a finished floor, or if it smells. A pad that soaked up pet urine or a leak will put the smell back into a freshly washed rug. The pet urine guide and the wet rug guide cover why.
5. Vacuum a pad that's staying. Both sides, then let it air out flat for a day.

When the rug comes back, lay the pad down first on a clean, dry floor, then unroll the rug over it pile side up. Turning the rug 180 degrees from where it was spreads out the wear from the walking path and the window side.

Getting the rug out of a Manhattan building

Pull the pad out first; then roll the rug from a short end with the pile facing in. If your building wants a service elevator reservation or a certificate of insurance for anyone collecting items, sort that out before booking. Our page on Manhattan rug cleaning with pickup covers doormen, service elevators and building documents, and the pickup prep guide covers rolling and tying. Pickup is usually within 48 hours of booking, or on a later date you choose.

What it costs

Standard washing is priced from the rug's measurements, width times length in feet without the fringe. Pickup and return are free when the cleaning subtotal is $250 or more, and $50 total below that. If furniture sits on the rug, the optional furniture service is a flat $50 and doesn't count toward the $250.
