Frequently Asked Questions About Floor Repairs

Q: Why do floors squeak more in winter?

A: Low humidity causes wood to contract, creating gaps between boards and subfloor. Heating systems dry indoor air. Humidifiers help maintain 30-50% humidity. Some seasonal squeaking is normal and resolves in spring.

Q: Can I install new flooring over damaged subfloor?

A: Never install over damaged substrate. Compromised subfloors cause premature failure of new flooring. Repair all damage first, ensure flat and solid. This prevents warranty voids and ensures longevity.

Q: How do I match old hardwood for repairs?

A: Take sample to flooring suppliers for matching. Consider harvesting boards from closets for visible repairs. Custom milling available for unique profiles. Refinishing entire floor ensures uniform appearance.

Q: Why did my tile crack with no impact?

A: Usually indicates substrate movement or inadequate support. Other causes: house settling, improper installation, or expansion issues. Investigate cause before repair or problem recurs.

Q: Should I repair or replace water-damaged laminate?

A: Laminate doesn't tolerate water well. Small areas: replace affected planks. Widespread damage: full replacement recommended. Address water source first. Consider waterproof vinyl plank alternatives.

Q: How long do floor repairs typically last?

A: Properly executed repairs match floor lifespan. Squeaks: permanent if addressed correctly. Tile: 20+ years with good substrate. Hardwood: indefinite with maintenance. Quality of repair determines longevity.
