Labor. The labor fees to install subflooring are usually between $25 and $30 per hour, but may vary based on your location and whether the job is straightforward or complex. Additional work—like removing existing flooring and subflooring, hauling old materials, or preparing a surface—costs extra.
The long beams that provide the main structural support for the floor can cost $200 to $500 per room or $10 to $67 per square foot to repair. A full replacement costs $5,000 to $20,000. If you're only repairing individual joists, expect to pay $100 to $300 per joist.
Larger houses and two-story houses may take longer. The cost of labor is typically between $4 and $10 per square foot. Materials run between $3 and $6 per square foot. Demand and urban builds tend to increase the cost of labor.
Subfloor replacement typically costs about $3 to $10 per square foot. This range can vary based on labor costs, which will add $25 to $30 per hour, and the type of subflooring you choose.
Subflooring can last a very long time. Under normal conditions, a subfloor can last as long as the house itself. However, should a subfloor be damaged or defective, it may only last 20 to 30 years. Should this be the case, a homeowner might need to peel back the layers of flooring and get to work.
The average cost of installing hardwood floors is $3–$10 per square foot for materials and $3–$8 per square foot for labor, totaling $6–$18 per square foot.

On average, the house framing cost per square foot is $7 to $16. This includes $4 to $10 framing labor cost plus $3 to $6 per square foot for materials.
Overall, interior walls framed with drywall tend to cost between $20 and $30 per linear foot, an estimate that does not include the additional costs of drywall screws, joint compound and joint tape.

Most of the time, the repair is pretty straightforward. A contractor will locate the broken joist and reinforce it by attaching a second joist next to it with structural screws and glue. The repair typically costs $250 to $300, according to experts who've done this type of work.
To avoid buckling, subfloor panels should be spaced with a 1/8-inch gap at all edges and ends to provide room for naturally occurring expansion. Tongue-and-groove edges on many premium floor panels, such as Weyerhaeuser's Edge Gold® OSB panels, are designed to self-gap.
Standard spacing for joists on 16-inch centers is ideal for most residential applications, while 24-inch centers are allowable under some conditions. For applications that require additional structural support, such as floors with heavy loads, closer joist spacing may be required.
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.
We do not recommend trying to remove and replace the rotten floor joist yourself. Once you identify the problem, or if you want to call professionals to find the problem, you can be sure that highly-trained contractors will do the best job possible.
In fact, framing is an intricate process that requires high-quality materials and skilled labor, making it a valuable investment in preserving your cherished memories. One of the key factors that contributes to the cost of framing is the use of high-quality materials.
Framing an entire home costs between $7 and $16 per square foot. So, a standard 2,000-square-foot home costs between $14,000 and $32,000. Framing a two-story house costs $3 per square foot more than a single-story house, so you'll need to factor in this additional cost if you plan to install a multi-story home.
When moisture penetrates your flooring, it can cause mold, mildew, and the potential for water damage. A moisture barrier helps control the water vapor's movement to help protect your floors. Therefore, if you're installing floors in an area that sees moisture, even a little, a vapor barrier is needed.
If the sub-floor has rotted or spongy in any way, it will need to be removed. However, if the sub-flooring appears strong and solid but simply wet, ventilate the area and allow time for the sub-floor to dry. It all depends on the amount of time the water was left to saturate the sub-flooring.
A subfloor is the bottom-most structural level of your floor. A good subfloor needs to be durable, level, at least 1 ⅛ inches thick, and free from residue.
A common sign of compromised joists is uneven floors. But these could be the result of flooring or subflooring defects. “Bouncy” floors are a very common sign of rotten floor joists. A musty or damp smell in certain rooms of your house is a clue to the presence of mold or decay.
