How long do hardwood floors last?
The National Wood Flooring Association's own figure is that wood flooring can last well beyond 100 years in service when properly maintained. The 50-year term on a Bruce solid floor covers the finish, not the wood — and sanding, which is exactly how a solid floor reaches its second century, voids that coverage by name.

Typical service life: 100+ years
NWFA's phrasing is that "wood flooring can last well beyond 100 years in service when properly maintained"; its homeowner handbook adds that solid wood "can be sanded and refinished many times." The 150 here only bounds the drawing, not the claim. What actually meters a solid floor is the wood above the tongue and how often it is sanded away.

A solid wood floor tracks the air in the room, not the weather outside — which is why the warranty picks a humidity band rather than a climate zone. Dry-winter heating country and humid-summer coastal country both move a floor; what matters is the size of the swing between them across a year, and a house held near the middle of that 30–50% band will keep a floor flat in either place.
What the warranty paper actually says
Bruce (AHF Products) (50-year limited solid hardwood (America's Best Choice, Bruce Pro, Dundee, Kennedale and other solid lines)) publishes a 50-year limited, non-transferable, conditional warranty. The 50 years is a finish warranty: for that period the factory finish is warranted not to wear through and not to separate from the wood — and the same footnote adds that "Mechanical, chemical, or other modification of the finish, such as sanding or abrading, voids this warranty." The wood itself sits under a separate line, free from defects in grading and assembly "for as long as you own the floor," and the paper allows one to three professional sandings following NWFA procedure. Coverage runs to the original retail purchaser and the document states in capitals that it is not transferable. Full bathrooms with a shower or tub are excluded outright, and holding indoor humidity between 30% and 50% is the owner's side of the bargain.

What shortens it
- Indoor humidity swinging outside the 30–50% band the warranty itself names — boards cup in the damp season and gap in the dry one
- Standing water at under-sink leaks, refrigerator lines and entry doors, which blackens and lifts boards from the edges inward
- Grit tracked in from outside, which works like sandpaper underfoot and thins the finish in the traffic lane years before anywhere else
- Pet claws and unprotected furniture feet, which cut through the finish long before the wood beneath is worn
- Sanding too often or too deep — every pass spends wood that cannot be put back, and thin-milled floors run out of it early
Signs of wear to look for
- Finish gone dull and grey along the walking lanes while the edges of the room still hold their sheen
- Bare wood showing at the pivot points — in front of the sink, at the foot of the stairs, in doorways
- Boards cupped so their edges stand proud of their centers, which is a moisture message from below
- Gaps that open between boards each winter and close each summer, and gaps that no longer close
- Black staining around a fixture or an exterior door, which is water that has been getting in for a while
A floor that springs, sags or moves underfoot across a whole room is a question about the joists and subfloor beneath the wood — that is an inspection question, not a web-page question.
