Quick Answer
Carpet installation in 2026 runs $3.50 to $11 per square foot installed (HomeAdvisor and Angi 2026 benchmarks), broken down as roughly $2 to $7 per sq ft for the carpet itself, $0.30 to $0.60 for padding, $1 to $2 for labour, and $0.25 to $0.75 for tack strips, transitions, and waste. A 1,000 sq ft house comes in around $4,500 to $9,000 fully installed.
Big-box "free installation" deals usually bundle the labour into a higher carpet price; the all-in number is similar.
Cost Breakdown by Carpet Type
- Polyester (PET): $1 to $3 per sq ft material. Cheap, stain-resistant, mats faster.
- Nylon: $2 to $7 per sq ft. Most durable residential fibre. Resists matting and crushing.
- Triexta (Smartstrand): $2 to $6 per sq ft. Permanent stain resistance, similar durability to nylon.
- Wool: $5 to $15 per sq ft. Premium look, natural, expensive.
- Berber loop: $1.50 to $5 per sq ft. Good for high traffic, pulls if pets snag the loop.
What Drives the Final Number
- Stairs: $2 to $7 per step extra. Waterfall is cheapest; wrapped/upholstered is priciest.
- Furniture removal: $200 to $600 if you want the installer to do it.
- Old carpet haul-away: $1 to $2 per sq yd.
- Padding upgrade: a 7/16 inch 8 lb rebond pad adds $0.20 per sq ft and extends carpet life 3 to 5 years.
- Subfloor repair: $1 to $4 per sq ft for plywood patching.
Money-Saving Tips
- Buy padding separately. Big-box stores upsell padding; specialty flooring shops are often cheaper.
- Schedule in the off season. November to February is the slow window for installers.
- Move furniture yourself. Easy $200 to $400 saved.
- Order remnants for closets and small rooms; carpet stores discount last-roll remnants 30 to 60 percent.
Frequently Asked Questions
What flatness does the subfloor need?
The industry default is 3/16 inch deviation over a 10 foot span (about 5 mm over 3 metres). Floating floors, rigid-core LVP, and engineered hardwood all share that spec. Tile is stricter at 1/8 inch over 10 feet because thinset cannot bridge a wavy slab.
How long should materials acclimate on site?
48 hours for laminate and LVP, 7 to 14 days for solid and engineered hardwood (until plank moisture content is within 2 to 4 percent of the subfloor). Skip it and you risk gapping in winter or cupping in summer.
Does this work over radiant heat?
Most rigid-core LVP, engineered hardwood, and porcelain tile are radiant-heat rated up to about 82F (28C) at the subfloor. Solid hardwood and bamboo usually are not. Always confirm the manufacturer spec before laying.
Is it the same in the UK?
The product categories and installation rules are nearly identical. UK retailers like B&Q, Wickes, Carpetright, and Topps Tiles carry the same Shaw / Mohawk / COREtec equivalents with British Standard labelling (BS EN 13329 for laminate, BS EN ISO 10874 for resilient flooring).
Pro Tips From the Trade
- Order 10 percent waste. Bump to 15 percent on diagonal layouts, herringbone, or rooms with lots of cutouts. Future repair planks need the same dye lot.
- Photograph the install. Subfloor, vapour barrier, expansion gaps, transitions. Warranty claims hinge on documentation.
- Keep one full carton. Same production run, stored flat in conditioned space. It is the only colour-true repair source you will ever have.
- Run planks toward the light. Parallel to the longest wall or toward the main window so seams disappear instead of catching shadows.
- Test moisture. Tape a 2 ft square of plastic to a concrete slab for 72 hours; condensation underneath means a moisture problem to solve before any flooring goes down.
Bottom Line
The product matters less than the prep. A flat, dry, clean subfloor with correct underlayment and proper acclimation will make a mid-priced floor outperform a premium one installed badly. Get those four basics right, follow the manufacturer's spec sheet, and you will not see a single one of the common failure modes (cupping, gapping, lifting, telegraphing) in the first decade.
How Much Does Carpet Installation Cost by Room Size
To put real numbers on how much carpet installation costs in your home in 2026, here are mid-grade nylon estimates installed (carpet + 8 lb rebond pad + labour + tack strips + transitions, 10 percent waste): a 12x12 bedroom (144 sq ft) runs $700 to $1,300; a 15x20 living room (300 sq ft) is $1,500 to $2,800; a 1,000 sq ft second floor with stairs is $5,500 to $9,500. Whole-house 2,000 sq ft starts around $9,000 and tops out near $20,000 for premium wool.
Big-box quotes for "free installation" still cost about the same on the bottom line because the labour gets folded into a higher carpet price. Always ask for the all-in price per square foot, padding included, before you sign.
Quick Buying Checklist
- Confirm the warranty covers your install type (residential vs commercial, DIY vs professional). Most manufacturers void the warranty if a non-certified installer skips moisture testing or acclimation.
- Buy 10 to 15 percent extra from the same production lot. Future repair planks have to match dye and texture exactly.
- Match the underlayment to the product. Wrong foam (too thick or too soft) is the #1 reason click joints fail in year two.
- Plan transitions at every doorway. Reducers, T-mouldings, and stair nosings are easy to forget and three times more expensive after the fact.
- Photograph the subfloor before the new floor goes down. Most warranty claims are denied for lack of install documentation.
Cross-reference the manufacturer's installation guide against the National Wood Flooring Association (NWFA) install best practices before you start. Mismatches between the two are common, and the manufacturer guide wins for warranty purposes but the NWFA guide wins for long-term durability.
