The natural luxury fiber — beautiful, breathable, expensive. Typical installed cost, durability, where it works and how to care for it.
Wool carpet is carpet made from real sheep's wool — the same natural fiber used in wool sweaters, not a synthetic plastic like most carpet. The wool is spun into yarn and tufted into a backing to form the pile you walk on. It's naturally springy, breathable and fire-resistant, which is part of why it costs more than synthetic carpet.
Wool has been the benchmark synthetic fibers get measured against for a century. Its scaled, crimped structure gives it natural resilience that just keeps springing back, and it's naturally flame-resistant without any added chemistry.
The lanolin in the fiber buys some time on a fresh spill, but wool is also highly hygroscopic — it absorbs and releases moisture from the air around it, which is exactly why a spill left too long stains where a synthetic fiber would simply have shed it. Wool is the most expensive mainstream fiber, and it's vulnerable to alkaline cleaners, moths and too much direct sun.
Wool is usually specified as a loop, and a claw that catches a loop pulls a run that can't be repaired invisibly. If you want wool with a dog in the house, specify cut pile. Urine is also chemically hard on wool, and the alkaline cleaners used to treat it damage the fiber.

Wool insulates by nature, which works against a system trying to push heat up through it. Workable with a thin, radiant-rated pad; not the natural choice.
Stretched broadloom — tools run roughly $80–$180 to buy
A room in a day, if the stretch goes right the first time. The technique is identical to any broadloom carpet, but wool costs more to get wrong and is less forgiving of a rushed seam. Most wool jobs are worth hiring out for that reason alone.
New Zealand wool (typically 32–37 micron) is the residential standard for carpet — coarser than apparel wool, which is what gives it bulk and resilience.
Wool self-extinguishes and has a high ignition threshold, which is why it appears in aviation and hospitality spec without added flame retardants.
Wool can absorb up to 30% of its weight in moisture without feeling wet, buffering indoor humidity swings.
80/20 wool-nylon is a common hospitality spec: most of wool's look and hand with a meaningful jump in abrasion resistance at a lower price.
Modern wool carpet is typically treated with a permanent moth-resist agent. Confirm this on any wool you specify.

Budget for professional cleaning as a line item. Wool rewards proper maintenance with 30+ year service and punishes the wrong chemical instantly.
Each feature paired with the benefit it delivers. A spec on its own tells you nothing about whether it is worth paying for.
Resilience without chemistry. Wool recovers from crushing better than any synthetic, which is why 30-year-old wool carpet still looks like carpet.
Repels water-based spills long enough to blot them, giving you a genuine grace period that synthetics without a treatment don’t offer.
Self-extinguishes and ignites at a high threshold with no added flame retardants, which is why it appears in aviation and hospitality specifications.
Absorbs up to 30% of its weight in humidity without feeling damp, buffering indoor humidity swings that would otherwise stress wood floors and furniture.
End-of-life disposal isn’t a landfill problem, and the raw material regrows on the sheep every year.
The specifications below decide how this floor performs. Ask for them in writing — a sample board and a price per square foot do not tell you any of it.
Wool Carpet runs $8.00–$22.00 per square foot installed in 2026 — $6.00 to $18.00 for material and $2.00 to $4.00 for professional labor. Spread across an expected 20 to 40 year service life that works out near $0.50 per square foot per year. Regional variation of 20 to 40% is normal, and demolition, subfloor prep and trim are extra.
20 to 40 years, assuming it went into an appropriate room over a properly prepared substrate and gets the maintenance it needs. Budget for professional cleaning as a line item. Wool rewards proper maintenance with 30+ year service and punishes the wrong chemical instantly.

Vacuum 2–3× weekly — wool sheds loose fiber for the first several months, which is normal. Blot spills with cool water and a wool-safe (pH 5–8) spotter. Critically: never use high-ph / alkaline detergents — they dissolve the fiber's protective scales.
