If you are replacing some wood siding that has become damaged by wood rot, then it is important for you to take steps so that your repaired areas do not suffer the same fate in the future. By taking certain steps while making your repairs, you can easily prevent future wood rot problems in your home's wood siding. Follow these time-tested tips to keep your wood siding wood rot free:

Tip: Always Countersink Screws and Use Wood Plugs

When you are repairing the wood siding on your home, it is vital that you use galvanized screws since they will come into contact with storm water. Since each screw's hole poses a water-leak damage area on your house, you should take the extra time and countersink each of the screws down into the wood. Fill each screw head's hole with a wood plug and glue it into place using a quality, exterior-rated wood glue product. This extra step will keep water from leaking down into the screw holes along your new siding and causing wood rot.

Tip: Prime All Sides of Wood Used on the Exterior of Your Home

Any wood that you use on the exterior of your home needs to be properly sealed by painting it with a primer. Before you install any new wood siding, you should first paint all sizes of each piece with an oil-based primer. Take special care to prime the ends of the lumber, since they are very absorbent and are often the location where wood rot starts. Since the primer will soak into the ends of your wood siding pieces, you can paint the ends with multiple coats of primer. Even if you choose to use a pressure-treated lumber for your home's siding, you still need to paint it with primer. Once installed, your home's new wood siding then needs to be painted with an oil-based paint.

Tip: Keep Wood from Having Contact with the Ground

Finally, it is vital in preventing wood rot on your home's siding that you keep all wood from having any contact with the ground. Wood in contact with the ground will absorb water and never truly dry out after a storm. If the wood stays wet for an extended period of time, then it develops dry rot and will need to be repaired again. Additionally, you must trim back any vegetation that comes into contact with the wood siding for the same reason.
