Carpet Replacement Guide: Costs, Options, and Timing

Updated March 2026 · By the FlooringCalcs Team

Carpet remains the most popular flooring choice for bedrooms, family rooms, and basements thanks to its comfort, warmth, sound absorption, and affordability. But knowing when to replace carpet, what to look for in new carpet, and how to budget for the project can be confusing. This guide walks you through every step from recognizing when your carpet needs replacing to choosing the right product and getting it installed at a fair price.

When to Replace Your Carpet

Most residential carpet lasts 5 to 15 years depending on quality, traffic, and maintenance. Signs that it is time for replacement include matting or crushing that does not recover after cleaning, permanent stains that resist professional cleaning, visible wear paths in high-traffic areas, a persistent musty odor (indicating mold or mildew in the pad), and significant discoloration from sunlight.

Carpet that has been properly maintained and regularly cleaned can last toward the upper end of its lifespan. However, even well-maintained carpet eventually breaks down at the fiber level, losing its resilience and ability to bounce back. If your carpet is over 10 years old and showing wear, professional cleaning will provide diminishing returns compared to replacement.

Pro tip: Before replacing carpet throughout your home, have one room professionally deep cleaned. If the results are dramatically better, cleaning the rest may buy you a few more years. If the cleaned room still looks tired, replacement is the right move.

Carpet Types and Price Ranges

Polyester carpet is the most affordable at $1 to $3 per square foot. It offers vibrant color options and good stain resistance but tends to mat and crush faster than nylon. It is best for low-traffic rooms like bedrooms and guest rooms. Olefin (polypropylene) is similar in price and is inherently stain-resistant, making it popular for basements and indoor-outdoor applications.

Nylon carpet costs $3 to $7 per square foot and is considered the best all-around carpet fiber. It offers superior resilience, durability, and a long lifespan. Brands like Stainmaster and SmartStrand use nylon or nylon-triexta blends. Wool carpet is the premium option at $8 to $20 per square foot, offering natural beauty, durability, and hypoallergenic properties but requiring more careful maintenance.

Pro tip: For the best value in high-traffic areas like living rooms and hallways, choose nylon carpet with a face weight of at least 35 ounces per square yard and a density rating above 2,000. These specifications indicate carpet that will hold up for 10-15 years.

The Importance of Carpet Padding

Carpet padding is the unsung hero of a comfortable, long-lasting carpet installation. It provides cushioning underfoot, absorbs impact that would otherwise wear the carpet fibers, insulates against heat and sound, and extends the carpet lifespan by 50 percent or more. Skimping on pad quality to save a few dollars is a false economy.

Standard residential padding is 7/16 inch thick with a density of 6 pounds per cubic foot, costing $0.50 to $1 per square foot. Premium padding at 1/2 inch thick and 8 pounds density costs $0.75 to $1.50 per square foot. For stairs, use a firmer, thinner pad (3/8 inch, 8-pound density) for safety. Memory foam padding ($1 to $2 per square foot) provides the most luxurious feel.

Pro tip: Always replace the padding when you replace the carpet. Old padding harbors allergens, odors, and moisture damage. Even if it looks fine, its cushioning ability has degraded. New carpet on old padding will underperform.

Installation Costs and What Is Included

Professional carpet installation costs $3 to $6 per square foot for labor, which typically includes moving light furniture, removing old carpet and pad, installing new pad and carpet, and basic cleanup. A full project for a 500-square-foot area including mid-range nylon carpet, standard pad, and installation costs $3,000 to $5,500.

Additional costs to budget for include: old carpet removal and disposal if not included ($1 to $2 per square foot), furniture moving for heavy items ($25 to $75 per room), stair installation ($15 to $30 per step), subfloor repair if damage is found ($2 to $5 per square foot), and new tack strips if existing ones are damaged ($0.50 to $1 per linear foot).

Pro tip: Big box stores like Home Depot and Lowes often run free installation promotions. Read the fine print: "free installation" usually means free labor with a minimum carpet purchase and may not include removal, moving, or stairs.

Smart Shopping and Negotiation Tips

Carpet is one of the most negotiable home purchases. Dealers have significant markup, especially on name brands. Get quotes from at least three sources: a big box store, a local carpet retailer, and a flooring warehouse outlet. Prices for the same carpet can vary by 30 to 50 percent between retailers.

Timing your purchase matters. Memorial Day, Labor Day, and Black Friday are traditional carpet sale periods with 20 to 40 percent discounts. Year-end clearances in December and January can yield even deeper discounts on discontinued styles. Carpet remnants and closeout rolls offer the best prices of all, often 50 to 70 percent off, if the size fits your room.

Pro tip: Ask for the carpet style name and fiber specifications, then comparison shop. Some stores use proprietary names for the same manufacturer carpet, making comparison difficult. The fiber type, face weight, and density specs allow accurate cross-shopping.

Frequently Asked Questions

How much does it cost to carpet a 12x12 room?

A 144-square-foot room with mid-range nylon carpet ($4/sq ft), standard padding ($0.75/sq ft), and professional installation ($4/sq ft) costs approximately $1,260. Budget options start around $700 and premium options can reach $2,500 or more.

How long does new carpet last?

Budget polyester carpet lasts 5-8 years. Mid-range nylon carpet lasts 10-15 years. Premium nylon or wool carpet can last 15-25 years. Quality padding, regular vacuuming, and professional cleaning every 12-18 months maximize lifespan regardless of fiber type.

Should I carpet or use hard flooring?

Carpet excels in bedrooms (comfort, warmth, sound), basements (insulation, comfort on concrete), and playrooms (safety for children). Hard flooring is better for kitchens, bathrooms, entryways, and formal living areas. Many homes use a combination based on room function.

Can new carpet be installed over old carpet?

It is not recommended. Installing over old carpet prevents proper stretching, hides potential subfloor issues, creates an uneven surface, and traps allergens and moisture. The cost savings of skipping removal ($1-$2/sq ft) are not worth the compromised result and shortened lifespan of the new carpet.

What carpet is best for allergies?

Contrary to popular belief, carpet can actually improve indoor air quality by trapping allergens that hard floors leave airborne. Choose nylon or polyester with low-VOC backing, use a HEPA-filter vacuum twice weekly, and have the carpet professionally cleaned annually. Avoid wool if you have a wool allergy.
