Carpet Installation Cost (2026)

The two numbers on the sample tag

Face weight is the weight of pile yarn on a square yard, backing and adhesive excludedFC-FaceWeight. Buy up rather than down:

• 25 to 35 oz for a bedroom or guest room.
• 35 to 50 oz for living and dining rooms.
• 50 to 70 oz and above for stairs, family rooms and commercial-grade trafficNFD-FaceWeight.

A second retail scale puts its middle boundary at 30 oz rather than 35FC-FaceWeight; order to the higher number. Under 30 oz, published service life falls below seven years; from 40 oz it reaches twelve and beyondHG-Carpet.

Density is the number dealers volunteer less often: face weight times 36, divided by pile height in inches, with 3,600 the published minimum for a living areaPMC-Density. A tall pile with little yarn in it computes low — and flattens in a traffic lane.

Fiber sets the ceiling

What the warranty asks of you

• The cushion decides the texture cover. Get HUD UM 72a, Class 1 into the written quote — one retailer's program honors that part of its warranty only over cushion meeting the federal specificationStainmaster-Warranty-Lowes.
• Cleaning is a duty. Plan on professional cleaning every 12 to 18 monthsCRI-FAQ and keep the receipt: the same program wants a hot-water extraction at your expense within 30 days before a claimStainmaster-Warranty-Lowes.

AllowancesDG-Roll; the order quantities are our arithmetic on them our arithmetic. Wall by wall, the method is in the measuring guide.

Roll width decides more than your tape does

Twelve feet is the standard broadloom width and the deepest stocked; 13.5 ft is worth asking about when a room lands just past 12 ft; 15 ft covers the most rooms without a seamDG-Roll. A room 10 ft wide, cut from a 15 ft roll, leaves 5 ft of width behind — 33 percent; the identical room off a 12 ft roll leaves 2 ft, or 17 percentDG-Roll. So ask which widths your style comes in before you commit to a color.

Where the seams go

Say where you do not want a seam before the order goes in. The count is arithmetic — room width divided by roll width, rounded up, gives the strips, and the seams are one fewerHowMuchStuff-Seams — but the placement follows the standard: seams run lengthwise, with traffic along them rather than across, out of raking light and not running square to a doorwayCRI105-Seams. Adjacent strips of the same broadloom lay with the pile leaning the same way unless the specification says otherwise, and pattern, appearance and economical use of the roll may all decide which way that isCRI105-PileDirection.

A professional measure runs $35 to $55, or nothing with an orderHG-Carpet. Take it: your figure sizes the budget, theirs sizes the order.

Included

• The carpet, at the grade you pick.
• The pad, priced as a required line at $0.46 to $1.17 per sq ft.
• Tack strip at $0.05 to $0.07 and doorway transitions at $0.02 to $0.13 per sq ft.
• The labor: cushion laid, carpet cut and seamed, power stretched onto the strip, finished at walls and doorways.

Not included

• Tearing out the old floor, moving furniture, stairs and subfloor preparation. All four start switched off, so turn on the ones your job needs before you hold this number against a bid.
• Hauling the old carpet and pad away, which stays a separate question even after tear-out is switched on: the published rate behind that switch covers pulling the carpet and disposing of it in one figureHG-Carpet, while a national calculator lists removing the carpet and carpet debris disposal as two options you tick one at a timeHomewyse-Carpet. Have the haul-away named inside the tear-out line before you sign.
• Baseboards off and back on, and doors trimmed to clear a thicker floorShaw-Costco.
• Seam tape, which is sold by the running foot rather than by the square footQ4-SeamTape — ask whether the bid carries it.
• Moisture or lead testing, permits and sales tax.

Buy the cushion on two numbers

Cut pile in a house takes cushion no thicker than 7/16 inch at about 6 lb of density; Berber and low-profile goods want 3/8 inch at 8 lbCRI-Select. The thickness ceiling comes from the residential installation standard, which names no density of its own and requires the cushion to match the carpet maker's specification for that productCRI-105-FullText. Ask for both in writing.

Ask for Green Label Plus on both samples

Ask for the Green Label Plus mark on the carpet and on the cushion, and get both onto the written quote before you compare two prices. The mark identifies low-emission goods and sits on the cushion sample as well as on the carpetCRI-FAQ; the two are separate products from separate makers, so a label on one says nothing about the other.

Behind the mark sits a test rather than a promise. Certified goods are measured against 35 individual compounds under the California CDPH standard method, each held to half its chronic reference exposure level and formaldehyde held to the full one; total volatile organic compounds are measured and printed on the certificate without being a pass mark of their ownCRI-GLP-Protocol. Read that as an emissions specification and nothing wider — one retailer puts it in its own warranty text that it does not represent its carpet will improve health or allergy conditionsStainmaster-Warranty-Lowes.

"Free installation" is a discount on one line

Where a retailer advertises free installation, the labor leaves the invoice but not the price — it is folded into the carpetDG-Prices. Removal at $0.50 to $1.50 per sq ft, furniture at $25 to $75 per room and transitions at $15 to $50 apiece stay where they were; across 1,000 sq ft the gifted labor is worth $500 to $1,500DG-Sale.

Conditions the standard requires

Check these before the crew arrives — ignored, they are the quiet cause of callbacksCRI-105-FullText.

• HVAC running, indoor temperature between 65 and 95 degrees F, relative humidity no higher than 65 percent, substrate surface at 65 degrees F or above.
• Those conditions held for 48 hours before the work, right through it, and 72 hours after — and never below 50 degrees F in the finished room later.
• Materials acclimatized in the room for at least 24 hours.

An empty, unheated house in February is a reason to move the date.

Mistakes that cost money

• Laying it without a power stretcher. The standard rejects substitutes that puncture the backing and names the outcome: wrinkling, buckling, a secondary backing that comes apartCRI-105-FullText.
• The wrong cushion. Too thick or too soft brings wrinkles, open seams and structural damage to the carpetCRI-Select.
• Re-stretching around the furniture. The room comes out empty and the floor is stretched mechanically in all four directionsCRI-FAQ — a vacancy, not an afternoon.
• Tack strip pinned the wrong way. Pins face the wall, never the roomDG-Strips.

Clear lamps, electronics and breakables yourself, whoever moves the furnitureShaw-Costco, and settle who takes the baseboards off. Before 1978 that question has a legal edge: the federal renovation rule exempts work disturbing 6 square feet or less of painted surface per roomEPA-RRP-FAQ, and baseboards are where a carpet job crosses it.

A power stretcher rents for $53.85 a day or $123.70 a weekRentall-Stretcher, and the standard makes its use mandatory — a knee kicker is a corner and stair tool, not a substituteCRI-105-FullText,HG-Carpet. One guide prices a DIY job at $1.25 to $6.00 per sq ft against professional labor of $0.50 to $1.50HG-Carpet. Carpet laid badly wears faster and voids the manufacturer's coverHG-Carpet, which is the line that should decide it.

Three questions surface the differences that matterHG-Carpet:

Then time the purchase. A promotion moves the material line 20 to 40 percent, closeout goods run 40 to 60 percent below list, and in a room under 200 sq ft a remnant saves 50 to 70 percent — the largest single discount on this pageDG-Sale. Ask your dealer for the date of its next promotion rather than planning a year around a calendar: one guide points to January, Memorial Day weekend and the week around Black FridayDG-Sale, another to fallHG-Carpet. Volume is the other lever: a 2,000 sq ft job carries far more weight at the counter than one bedroomDG-Sale. Whatever the discount, never pay in full up front and never default to the cheapest bidHG-Carpet.

Then plan for what you are buying. Carpet lasts 5 to 20 years depending on fiber, traffic and care, with cleaning at $25 to $70 per room and re-stretching at $50 to $80 per room along the wayHG-Carpet. If that does not suit the room, vinyl plank installs at $4.75 to $13.25 per sq ft, hardwood at $7.50 to $14.50 and engineered hardwood at $6.25 to $15.25; the flooring cost hub has the rest.

Published per-step figuresHG-Carpet. For the flight as a whole, budget that $130 to $585 and keep $600 in reserve once it turns onto a landing — that is where published figures for a full flight top outHG-Carpet.

Order for the wrap, not for the bare figure. Tread plus riser comes to about 4.06 sq ft a step, or 52.8 sq ft over 13 steps, before the front edge is folded over anything; installers add roughly 6 inches a step for the nosing wrapSQFC-Stairs. The measuring guide works a flight through end to end.

The labor follows from the standard: a nosing radius of 3/4 to 1 inch keeps the edge from cutting through carpet and cushion, waterfall installation sets tack strip on the tread and again on the riser, and cap-and-band uses none on the riserCRI-105-FullText. Fifty square feet of stairs is hand work an open bedroom four times the size never asks for.

One clause belongs in the decision as much as the price does: including stairs shortens one retailer's texture retention and wear cover by ten years, and pet stains on them fall outside itStainmaster-Warranty-Lowes.

Carpet's figures rest on four inputs: list prices for 23 carpet products from 3 dealers, collected in August 2026; federal wage statistics for carpet installers by state; our own August 2026 survey of cushion, tack strip and doorway transitions; and 6 documented sources for labor hours, several of which never state a crew size. How these numbers are built carries the whole chain, and the flooring cost hub carries the other floors we price. These are modeled national and state-level ranges, not quotes.
