Sobre Este Material

Carpet is sold by the square yard (9 sq ft) and comes in rolls that are typically 12 or 15 feet wide. The most common fiber types are nylon (most durable, $3–$8/sq ft), polyester (soft and stain-resistant, $2–$6/sq ft), olefin/polypropylene (budget-friendly, $1–$4/sq ft), and wool (premium, $8–$20/sq ft). Carpet pad is essential and adds $0.50–$1.50 per square foot — an 8 lb, 7/16-inch thick pad is the minimum for residential use, while higher-density pads extend carpet life. Total installed carpet costs range from $3 to $12 per square foot including pad and labor. Carpet seams should run perpendicular to windows to minimize visibility. For stairs, add 1.5 linear feet per step for proper tucking. Commercial carpet tiles (typically 24x24 inches) are an alternative that eliminates waste from roll cuts and allows easy replacement of damaged sections. Most residential carpet carries a 10–25 year warranty depending on fiber type and construction.

Consejos de Instalación

• •Always install carpet pad before carpet — it extends carpet life by 50% or more.
• •Run seams perpendicular to the main light source (windows) to hide them.
• •Stretch carpet properly with a power stretcher, not just a knee kicker, to prevent buckling.
• •Use tackless strips around the perimeter, set 1/2 inch from the wall.
• •Leave carpet and pad in the room for 24 hours before installation to acclimate.

Errores Comunes a Evitar

• ⚠Using a knee kicker only — power stretching is required for proper installation.
• ⚠Choosing too thin a carpet pad — 7/16 inch, 8 lb density is the minimum.
• ⚠Not accounting for pattern matching — patterned carpet requires 10–20% extra.
• ⚠Running seams parallel to windows where light highlights the joint.
• ⚠Forgetting to add carpet for closets, hallways, and stairs.
