However, it plays a major role in supporting certain types of flooring, like hardwood floors or carpeting, which can't be attached directly to the floor joists in your home. A subfloor can last up to 30 years but does eventually need to be replaced.
How Long Does Subfloor Last? Subfloor typically lasts 30 years or more, but if it is consistently exposed to moisture you may need to replace it sooner.
There are many signs that your damaged subfloor should be replaced with a new subfloor. These include squeaks and other noises, cupping or warping, cracked or popped tiles, sagging or unevenness, the smell of mold or mildew, or bubbling tile.
Taking all these factors into account, subfloor material costs can range from as low as $2.50 per square foot for plywood to as high as $10 per square foot for Amdry or Barricade. Common subfloor materials include plywood, oriented strand board (OSB), Amdry, DRIcore, Barricade, Warmboard, and concrete.
Signs may include loose flooring pieces or a floor that is undulating and uneven in areas. Wet or water-damaged subfloors that are structurally unstable can cause long-term problems with your home, and simply replacing the wood floor on top will not fix the problem.

Does homeowners insurance cover subfloor? In general, homeowners insurance covers subfloor water damage. However, it must be caused by one of the perils listed in your insurance policy.
While it may seem tempting to replace the subfloor from underneath if your home has access from the basement to this area, it should always be replaced from the top.
What are the costs to fix sagging floors and subfloors? The typical costs for repairing sagging floors start at $1000 and can go up to $10,000, with the average rate being around $300 per square foot. But this can vary depending on the extent of the damage and materials needed to get the job done.
Given the complexity of subfloor repairs, you should really stick with a carpenter for this project. But if you want to install a new subfloor or underlayment over sound floor joists, hire a local flooring contractor for this step.
Replacing subflooring is a relatively complicated task that requires precise measurements. You'll need to make sure all of the parts of your floor are structurally sound. That said, you don't always need to replace the entire subfloor. If only a portion is damaged, you can patch it.
An uneven subfloor is most likely to be the culprit for that spongy feeling if the issue is not evenly distributed but confined to specific areas – particularly if you can rule out causes such as water damage if, for instance, the flooring is newly installed.
Subfloor mold can appear as dark spots or patches beneath flooring materials like carpets, vinyl, or laminate. It often grows on plywood or OSB substrates, common since the 1950s. The presence of subfloor mold can be hinted at by a musty odor.
Safety factor is a measurement with which your floor was designed to support loads without collapsing. Most homes have a safety factor of 40 PSF (pounds per square foot).
Plywood is the most common subfloor and is a popular choice because of its strength, durability,and ease of installation. Plywood subfloors are made of layers of wood veneer that are then glued together. Plywood can be used with a variety of flooring materials.
For an average-sized room of 300 square feet, expect to spend about $900 to $3,000 on the cost to replace subfloors, or $3 to $10 per square foot. Most homeowners spend about an average of $1,560. Laying down a new style of flooring, like marble or linoleum, might require a new subfloor.
Does home insurance cover foundation movement or sagging floors? Foundation damage caused by shifting or settling earth or sagging floors caused by rotting floor joists are typically not covered by homeowners insurance. If the damage is caused by flooding or an earthquake, you'll typically require separate coverage.
It's difficult to assess if the sub-floor is rotting until carpets or tile are pulled back and an inspection is conducted. However, if the sub-floor feels spongy and sags when walking across the floor, this is a sign of a rotted sub-floor.
Generally, no. Insurance would cover a sudden loss event. A slow leak causing rot over an extended period of time is not a sudden loss event.
A wet subfloor doesn't always need to be replaced, but it must be thoroughly dried and assessed for damage. Use fans and dehumidifiers to dry it out. If the subfloor is swollen, warped, or has mold growth, replacement is necessary.
You have the top layer that is your floor covering (Hardwood, Laminate, Vinyl, Carpet, etc.), next you have the underlayment (usually a thin layer of fiber, foam, rubber), below that you have your subfloor (plywood, OSB, concrete), and lastly you have the joists which are the foundation to your floors.
Home and condo insurance typically covers floors and carpet if the damage was caused by a covered peril. Scratches, dents, spills, and other mishaps may not be covered.
A flooring contractor can replace subfloor.
Whether a homeowner is replacing rotted subfloor resulting from water damage or patching smaller sections that have deteriorated over time, a structurally sound, flat surface is required to serve as the support for tile, hardwood, or vinyl flooring.
Most homeowners pay between $1,000 and $8,500. Costs vary greatly depending on the type and extent of the damage. Sagging floor repair costs an average of $1,000 to $8,500.
