Top 10 Claims that are NOT covered under Manufacturer’s Warranties
Gapping is caused from a reduction in moisture content since the day of installation. Most commonly, lack of proper humidification being exposed to the wood within the home.
Checking/cracking is also caused from a decline in moisture content from time of install. Most commonly, lack of proper humidification being exposed to the wood within the home.
3- Radiant Heat
Radiant heat can cause excessive shrinkage, gapping, cracking and checking if the system is not running properly. The subfloor temperature should not exceed 82 degrees and RH should not go below 30% (or per manufacturer’s Guidelines for RH levels).
Sidebonding is a condition which has a direct result from reducing moisture content in the wood from low RH levels. Water based finishes are more prone to have this condition over oil base finishes.
Buckling is an event that causes the floor to lift off the subfloor and resembles a tenting look to the floor. The cause of buckling is from excessive moisture exposure to the installed wood floor thus swelling to boards. The boards push against each other until it gives and pops off the subfloor.
Noise within the floor systems are usually related to fasteners. Whether it’s over/under driving fasteners, wrong fastener length or size, broken lower groove or cracked tongue. Another possibility is when the floor is exposed to variations in moisture content from time of install. The floor swells in the summer months and then, once the heat goes on, and lowers the RH in the home, this shrink and swell can loosen the fastener and create noise.
7- Sanding Marks
Sanding marks are a direct result of inadequacy of the floor technician.
Debris/hair/dust may be prevented by a qualified mechanic. If not predominant throughout the floor and can’t be seen from a standing position, it’s not a complaint.
9- Movement – Floating Floors
Movement within floating floors is normal, HOWEVER, many inspections reveal this movement to be excessive because the subfloor flatness is outside the parameters of the NWFA or manufacturers guidelines.
Cupping is a moisture content imbalance throughout the thickness of the flooring. This is a site related problem and usually associated with elevated subfloor moisture. This causes the bottom of the wood flooring to swell while the top of the wood flooring stays consistent thus creating a cupped look.
