Guide FAQ
How wide is carpet?
Standard rolls are 12 ft wide — rooms wider than that need a seam.
Is pad really necessary?
Yes — pad is a third of the comfort and half of the lifespan.
How much does carpet installation cost?
Roughly $3–$6 per sq ft installed including pad in most markets.
What pile for bedrooms?
Medium cut pile (fewer footprints) or textured saxony; skip high loop for pet claws.
Can new carpet go over old pad?
Never reuse pad — it holds a decade of dust and voids warranties.
