Most homeowners assume the price on the showroom tag is the price they’ll pay. It rarely is. The right carpet supplier bundles padding, tack strip, transitions, stair work, and old-carpet removal into a quote that can swing your final cost by $1,000 or more on an average house. Knowing how suppliers differ before you walk in saves you from the upsell and gets you a floor that actually lasts.
The Three Types of Carpet Suppliers
Your options fall into three buckets, and each has a clear trade-off. Big-box retailers like Home Depot and Lowe’s carry national brands, run frequent installation promotions, and offer financing, but their installers are subcontractors you never meet until the day of the job. Pricing runs roughly $2 to $5 per square foot for the carpet itself, plus $0.50 to $1 per square foot for installation.
Local flooring dealers and independent showrooms sit at the higher end on sticker price but often beat the big boxes on total value. They carry mill brands such as Shaw, Mohawk, and Stainmaster, employ their own crews, and stand behind the work directly. Online suppliers like Carpet Express or FlooringInc round out the field, shipping mill-direct rolls and carpet tiles at 20% to 40% below retail, though you arrange your own installation.
What a Carpet Supplier Should Quote Beyond the Carpet
A complete quote has at least eight line items. If your supplier only gives you a per-square-foot number, push for the full breakdown so nothing surprises you on installation day.
- Carpet: $2 to $7 per sq ft depending on fiber and face weight
- Padding: $0.30 to $0.75 per sq ft; 8-pound, 7/16-inch rebond is the residential sweet spot
- Installation labor: $0.50 to $1.50 per sq ft
- Tack strip and seam tape: usually $0.10 to $0.25 per sq ft
- Stairs: $5 to $15 per step, more for wraparound or box installs
- Furniture moving: $50 to $200 flat, often waived in promotions
- Old carpet removal and disposal: $1 to $2 per sq ft
- Transitions and metals: $5 to $20 per doorway
Reading Carpet Specs Like a Pro
Suppliers throw around three numbers that determine durability: face weight, density, and twist. Face weight measures ounces of fiber per square yard; 35 to 45 ounces handles a busy family room, while 50-plus suits stairs and hallways. Density, calculated from face weight and pile height, matters more than weight alone. A tightly packed 35-ounce carpet outperforms a fluffy 45-ounce one.
Twist level, listed as TAC (twists and tufts), tells you how well the carpet resists matting. Look for 5 or higher in frieze and textured styles. Ask any supplier for the manufacturer’s wear rating, typically a 1-to-5 PAR (Performance Appearance Rating) scale. A 3.0 or above is appropriate for whole-home use.
Fiber Types and Where They Belong
The fiber drives both feel and price. Nylon is the workhorse, the most durable and resilient choice for high-traffic homes, and it carries the highest cost at $3 to $7 per square foot. Polyester (PET) feels soft and resists stains well at $2 to $4 per square foot, but it crushes faster under heavy furniture.
Triexta, sold under the Mohawk SmartStrand name, blends nylon-like resilience with built-in stain resistance and works well for households with pets and kids. Olefin (polypropylene) is the budget berber and outdoor option; it shrugs off moisture and bleach but mats quickly indoors. Match the fiber to the room rather than the showroom lighting.
Vetting Your Supplier and Installer
Before you sign, confirm the installer is certified by the Certified Flooring Installers (CFI) program or carries manufacturer training. A poor installation voids most carpet warranties, so this matters as much as the carpet itself. Ask whether seams will be power-stretched with a knee kicker and stretcher rather than simply rolled, which prevents the rippling that shows up six months later.
Check that the supplier files your warranty registration; many texture and stain warranties require professional installation and a registered receipt within 30 to 60 days. Read the fine print on labor warranties too. Reputable local dealers back installation for one year; big-box subcontractors may offer less.
Timeline and Ordering Tips
In-stock carpet from a big-box store can be installed within 7 to 10 days. Special-order mill carpet runs 2 to 4 weeks, longer for custom colors. Order 5% to 10% extra material for pattern repeats, stairs, and future repairs, and keep a remnant rolled in the garage.
Measure your rooms yourself before the in-home estimate so you can sanity-check the supplier’s square footage. Carpet sells in 12-foot-wide rolls, so a 13-foot-wide room forces a seam and extra waste. A good supplier will plan seam placement away from sightlines and high-traffic paths, which is the kind of detail that separates a professional carpet supplier from a vendor just moving boxes.
Pro Tips to Save Money
Time your purchase around major sale windows: the months after the winter holidays and Memorial Day weekend routinely bring free-installation or buy-one-room promotions. Never pay full retail on padding; upgrading to 8-pound rebond costs pennies more per square foot than the builder-grade 6-pound and roughly doubles the carpet’s lifespan and comfort underfoot.
Finally, get at least three written quotes on identical specs. Suppliers price the same Shaw or Mohawk style very differently, and showing one quote to another dealer is the fastest way to a discount. With the breakdown in hand, you control the conversation instead of the salesperson.
Questions to Ask Before You Sign
A short list of pointed questions separates a thorough supplier from a careless one, and it surfaces hidden costs before they appear on your invoice. Ask each of these during the in-home estimate and write down the answers so you can compare bids fairly.
- Is the installation cost included, or quoted separately per square foot?
- Who actually installs the carpet, in-house crews or subcontractors?
- Does the price include moving furniture and hauling away the old carpet and pad?
- What padding grade is included, and what does an upgrade to 8-pound rebond cost?
- How are stairs and transitions priced, and are they in the quote?
- What is the labor warranty, and does the manufacturer warranty require professional installation?
- What is the lead time, and is the carpet in stock or special order?
A supplier who answers these clearly and puts them in writing is one you can trust. Vague answers or a refusal to itemize the quote are red flags that the final bill will climb on installation day. The best carpet supplier earns your business with transparency, not just the lowest sticker price.
To sanity-check any quote yourself, measure each room’s length and width in feet, multiply for square footage, and add 10% for waste, seams, and pattern matching. A 12-by-15-foot bedroom is 180 square feet, so you’d order about 198 square feet. Carpet is sold by the square foot at retail but priced by the square yard at the mill, so divide square feet by 9 to convert. That 198 square feet equals 22 square yards.
Knowing your own numbers keeps a supplier honest and helps you spot an inflated estimate. If a salesperson’s measurement comes back 20% higher than your careful figure, ask them to walk you through it; legitimate extra material for seam placement and stairs is reasonable, but padding the order to inflate the bill is not. A reputable dealer will gladly show their measurement diagram.
