Before you start doing your repairs, you must first know the cause, where the damage is, and what repair you must do. Some signs of foundation damage are gaps and cracks in your house’s interior, such as walls and door frames. Shifting and misalignment are some of the results of wooden foundation damage.

When doing your assessment of damage, start to look at what you think is more exposed to water hazards such as posts near pipelines and waterways. This can save you time searching for potential damages as these parts of the foundations are near the primary cause of damage.

While you are at it, also check for other damage-inducing factors such as termites.

Step #2. Repair or replace

After dealing with the source of damage to your wooden foundations, assess whether the damage needs repair or a replacement. It’s better to look at the type of damage your wood foundation has before doing the replacement.

If the damages are minimal and are limited to water stains and molds, it does not warrant a replacement for your wooden foundation. Just wipe the surface down and apply sealant or a waterproof coating so that moisture won’t further damage the structure and that molds won’t come back.

If you found small cracks on the wood foundation but the structure is still sturdy, you can decide whether to replace or just apply a sealant or filler into the gaps depending on your assessment of the damage. When the damages are pretty disturbing such as wood rot, softening of the wood due to excessive water exposure, and wide cracks, it’s better to replace the structure than patch it up.

When doing the replacement, don’t forget to put temporary braces and posts to support the area where the wood foundation needs replacing. Measure the foundation that needs replacement and cut your replacement accordingly.

Try selecting a wood of premium quality so that the structure would be long-lasting and worthwhile. Place and secure the new foundation in place before taking your temporary posts and braces.


Step #3. Apply protective coats

Ensuring that the newly repaired wood foundation would be preserved from damages, it’s better to apply various wood preserving methods in the wooden structure. Sealants, varnish, and paint primers would do good for your foundation.

Applying these kinds of protective measures will not only preserve your wood foundations from water damage, but also from other damage-inducing sources such as termites. Using preventive measures will always be beneficial in a lot of ways.


Step #4. Finish up

After doing your work on your foundation, it’s time to finish up. Restore back everything in place and secure your job correctly. Also, try to think of some more ways to prevent damages from occurring in your wooden foundations.

Things like setting up drainages, plugging holes and cracks in your roofing, and even landscaping would help. When preventive measures and maintenance are done correctly, the lifetime of any structure or furniture you have will be prolonged.
