If you have had a flood or a pipe has burst in your home, there’s a good chance the subfloor may be damaged and need to be replaced. Follow these steps to help you replace it if your skills are up to it. If you are less experienced or do not have enough time, I recommend asking a professional for help. In some situations, the subfloor damage can be challenging to check and replace if needed.
It’s always a good idea to get a good look at things before you start any repairs. Be sure to pull up the flooring in your home so you can have a good look at the subfloor. Once you know how bad the damage is, you can come up with the best way to repair or replace it.
Take some time to inspect the area and mark the parts that need to be replaced. You may not need to replace the entire floor, but you will need to work on the damaged sections. You should measure and mark with a piece of chalk or a marker.
Use a saw to cut out the damaged areas. Be sure to make your cuts clean so you can easily fit in the new subfloor. The more accurately you measure and the straighter you cut the damaged pieces, the easier adding the new subfloor and the better the finished result will look.
Put your new flooring in the proper location. Be sure to secure it in place and pound flat any screws or nails that could be sticking up. The new subfloor should fit right in the space of the old portions that were removed.
If you plan to install new flooring over the sunflower, you can do so. Be sure to clean up the area to ensure no dust or dirt could prevent the new flooring from adhering to the subfloor or cause lumps and bumps that might lead to more damage.
The subfloor may not need to be replaced as long as you are able to remove the water quickly. It takes some time for the water to get under your surface flooring and damage it. By removing the water quickly, you won’t have to worry about it damaging the subfloor. Of course, it also depends on the type of subfloor. When it is, for example, made from concrete, you have less to worry about.
If you notice the water has been on your subfloor for a while, you may need to replace the subfloor. Before you start working on your floor, be sure to check for some of these issues that will tell you the repairs are necessary:
Check the floors to see if any parts look uneven. You may notice that some areas appear to be sunken in, or some parts are higher than others. It could mean the subfloor is damaged and will need to be replaced.
If you step on the floors and feel them moving, it may mean you need to replace the subfloor. The subfloor can be soft in some places and may give out when any weight is put on it. It can take some time for the floors to become soft or loose enough to shift, but once it starts to happen, it can affect the entire floor.
There are many reasons your floors may squeak, but if you recently had a flood or a leak and there is a chance the water could have gotten into the subfloor, the squeak could be a sign that it’s time to replace it. The squeak will likely get worse as time goes on, and it could be really noisy in your home.
You likely have furniture in your room, and if you notice that it no longer sits right and seems to be tilting or uneven, it may mean the subfloor is weak. Furniture is heavy, and if the flooring is soft, the furniture may be sinking into it and even poking through it. Even if the leak or floor didn’t occur in the same room, it might have spread to that area and made that subfloor weak.
If you notice cupping on your floor, it could mean that there is still water in the subfloor or that the subfloor has become so weak it can no longer support the flooring in your home, and it is starting to buckle from the weight. In some cases, you can make repairs, but you may need to replace it if it is severe.
If you are in a house that has more than one floor, and you notice the ceiling above you is leaking, it may mean that the flooring on that floor is damaged and needs to be replaced. A leak could cause this in a pipe or a flood in the bathroom.
You may not even know there is damage to the floor until you see the water dripping from the ceiling. This might also mean that you need to replace your ceiling.
You won’t always see signs that your subfloor is damaged and needs to be replaced. Sometimes you will smell the signs first. If you walk into your room and notice there is a musty or moldy smell, it may mean that the water has made it down to your subfloor.
Mold may be growing and causing the smell, or there may just be water inside the subfloor that you can smell when you walk into the room.
Will the Wet Subfloor Dry Out?
Your subfloor will dry out in time, but the sooner you can dry it, the less likely there will be as much damage. The longer the water is left on the subfloor, the more likely the floor will swell and become damaged.
Once the subfloor has absorbed enough water to swell, it may have to be repaired or even replaced. Always act quickly if and when you see water on your floors so you won’t have to worry about it soaking into the subfloor and causing more costly damage.
If you think there could be moisture in your subfloor from a leak or flood, you may be worried about what the moisture will do if it’s there for a long time. There are a few ways to remove the moisture from your subfloor so it doesn’t become damaged.
In general, ventilation is key. If you plan to use natural ventilation, always know that this only works if the humidity outside is at an average level. If you live in a humid area, you probably need to use other measures like a dehumidifier or your AC.
Here are a few measures to get the moisture out of a subfloor:
While this could be a slow process, you can let the room air dry without other measures. It will likely take some time for all the moisture to leave the subfloor, and it could have already caused damage by the time it dries.
You can help move the air around in your room by opening the windows. With air circulation, your subfloors are more likely to dry faster. Since you need to work fast, anything that can help move the moisture out is a great option. Opening the windows will pull out any moisture and help it dry faster.
Fans can also help dry out a room or a subfloor. If you are able to set up commercial fans, they may work even faster. Personal fans can also work if that’s all you have. The fans will help move air around in the room and reduce the chance of the subfloor getting so wet that it starts to swell or allow mold to grow.
As long as you are able to change them out as needed, you can use towels to help pull out the moisture that may be in the subfloor. Once the towels are saturated, you should remove them and put down dry ones to continue to absorb the water.
● Remove Moisture From A Subfloor: Dehumidifier or your air conditioner
A great way to quickly remove moisture from your subfloor is by using a dehumidifier or your air conditioner system. This is particularly true if you live in an area where the humidity outside is high.
You can use a residential dehumidifier, but I always recommend renting a commercial dehumidifier. They can remove a lot more water per hour than a residential dehumidifier.
A dehumidifier pulls in the moisture from the air and dries it out to release dry air back into the room. When used with a fan, this can be highly effective at drying out the drywall quickly.
Suitability of Wet Plywood Subfloors
Even after getting wet, plywood subfloors can remain suitable for use. The key lies in ensuring they are properly installed and tightly fitted together with nails or screws. This robust installation minimizes the potential for negative impacts that moisture can cause.
• Dealing with Slight Warping
During the drying process, it’s common to notice slight warping on the edges of the subfloors. However, this shouldn’t be a cause for concern. In most cases, the warping can be corrected by simply nailing or screwing the edges back to their original position.
• Replacing Bowed Plywood Subfloors
In instances where moisture damage has caused significant bowing in the subfloor, prompt replacement is advised. It’s best to cut out the affected areas and replace them to prevent further damage.
• Creating Optimal Conditions for Drying Indoor Plywood Subfloors
Creating the right conditions for drying a plywood subfloor can expedite the process significantly. There are a variety of ways to achieve this: increasing room temperature, turning on the heating, opening a window, or using a dehumidifier.
All of these will go a long way toward reducing humidity and creating an environment conducive to drying.
• Dealing with Outdoor Plywood Subfloors
Drying plywood subfloors outdoors presents a different challenge, as weather conditions are unpredictable. However, the emphasis here should be on mitigating water exposure during construction rather than fixing issues after exposure.
• Handling Minor Water Leaks on Subfloors
Generally, sporadic minor water leaks are unlikely to cause long-term damage. However, it is advisable to clean up spills promptly and to dry the wood as fast as possible to prevent moisture from spreading.
• Timing and Considerations for Sealant Application
After a leak, indoor subfloors typically dry out in a couple of days, depending on the severity of the leak. It’s crucial to ensure the subfloor is fully dry before applying any sealant or installing a finished floor. This wait is necessary to prevent trapping moisture underneath, which can lead to damage in the long term.
• Moisture Reduction Tactics
Apart from increasing the room temperature, other moisture reduction tactics such as mopping up excess water, using a dehumidifier, or opening a window can aid in reducing the subfloor’s moisture content.
• Importance of Ventilation
Ventilation plays a pivotal role in the drying process; it should not be overlooked. Without proper airflow, residual moisture may lead to wood rot. For a deeper understanding of the role of ventilation, you could read up on this article on
Barrie Home Inspection the website here.
• Preventing Dry Rot and Mold Growth
Boosting the airflow under the subfloor can prevent dry rot and mold growth. In severe leak cases, removing a plank to allow airflow can speed up drying.
• Drying Outdoor Subfloors After Rain
Outdoor subfloors that have been heavily rained on should ideally be left to dry naturally under sunny weather conditions. If long-term rainfall is expected, untreated plywood sheets should be taken inside or covered to protect them from water exposure.
• Recommended Types of Plywood
For the best protection against water damage, WBP plywood, Marine Grade plywood, or pressure-treated plywood come highly recommended owing to their superior water resistance compared to other types of plywood.
• Protecting Subfloors from Moisture
Covering subfloors when they’re not in use, especially overnight and during periods of high moisture, is critical. Various materials like rosin paper or fan fold insulation with Luann on top can be used to cover subfloors. Consequently, seams should be taped to prevent any water seepage.
• The Drying Process of OSB
In many construction or renovation projects, it’s critical to understand that Oriented Strand Board (OSB) dries slower than plywood.
This difference stems from the unique characteristics of the materials used in OSB’s manufacture. To ensure effective drying, it is crucial to understand and follow appropriate procedures.
• Surface Moisture Removal From OSB
Eliminating surface moisture accumulated on OSB can be achieved by sweeping or sucking. The excess water should be swept off or vacuumed up when identified.
This is an essential first step before proceeding to other drying methods. It is important not just for the drying process but also to guarantee the material’s integrity.
• Water Draining in OSB
For larger puddles of water, more stringent approaches may be necessary. One recommended technique is drilling holes into the OSB to facilitate water drainage. This effective method can help diminish the total water content within the material, speeding up the drying process.
• Use of Carpet Drying Fans in OSB Drying
The use of carpet drying fans is a common and highly effective method for drying out OSB. These fans are designed explicitly for the job and help to significantly speed up the drying time by promoting proper airflow. This plays a crucial role in removing moisture trapped deep within the OSB layers.
• Attention to Detail: OSB Joints, Corners, and Edges
When working with OSB, never neglect the finer details. Particular attention should be dedicated to drying the joints, corners, and edges of the OSB. These areas are notorious for retaining moisture and, if overlooked, can lead to mold or rot problems which can compromise the structural integrity of the OSB.
• Moisture Testing of Dried OSB
Once every precaution and procedure has been pursued, bringing out a moisture meter is a critical step to confirm that the OSB is now sufficiently dry. The OSB must be moisture-free to meet safety standards and ensure efficient performance.
• Repairing Moisture Problems in Existing Homes
Addressing a wet subfloor in an existing home involves first fixing the source of the water leak or moisture problem. Without resolving the moisture issue at its origin, the subfloor may continue to get wet and cause problems.
• Checking Existing Home Subfloor’s Moisture Levels
It is also advisable to pull up sections of the finished floor to test the underlying subfloor’s moisture level in an existing home. Persistent dampness can lead to the growth of mold and can compromise the structure. If the moisture level is above 20%, the affected subfloor needs full and immediate attention.
• Removing the Finished Flooring in Existing Homes
Depending on the moisture level, it might become necessary to remove the finished flooring to expose the entire affected subfloor. This allows for a detailed investigation of the dampness and a more efficient resolution of the problem.
• Handling Structurally Compromised OSB
If the OSB in a wet subfloor appears structurally compromised, the recommended action is removal. A damaged OSB can impact the integrity of the entire structure and poses a safety risk.
• Use of Commercial Fans and Dehumidifiers
Drying out the remaining damp OSB in an existing home can be achieved using powerful commercial fans and dehumidifiers. These machines promote effective evaporation, considerably bringing down the moisture levels within the subfloor.
• Moisture Tests Post Drying
Upon completion of the drying process, it is advisable to run another moisture test. This step ensures that the subfloor is dry and thereby prevents potential structural issues in the future.
• Final Stages: Replacement and Finishing
Once the wet subfloor issue is resolved, it’s time to replace any removed OSB and install the finishing materials. This step signifies the successful restoration of the subfloor and its complete readiness to support the home structure.
For more in-depth guidance and resources, I strongly recommend visiting a site like the National Wood Flooring Association’s official website, a reputable .org site that offers valuable guidance on dealing with wet and damp wood materials.
