repairing a rotted exterior door
Without any protection, like a recent coat of paint, a wooden exterior door will eventually begin to rot. This process is sped up by all of the moisture in the air created by Toronto’s seasonal changes. Regardless of whether it’s an interior or exterior door, rotted door frames are no good. Read on to find out how to fix a rotted door frame including the door and trim.

1. Set-up To Repair the Rotted Door

First, locate the hinge pins on the exterior door and slide them out. Place the door on a fairly flat surface with the damaged area facing upwards. With a putty knife, scrape away any old loose paint. This will make it easier to see the entire door and what areas need repair. If you find any rot, pry it up with a screwdriver for easier removal. Be careful of your eyes as paint and wood chips may fly off. Use safety goggles if preferred.

2. Drill & Fill for Repair

With your drill, make 1/4″ holes in, but not right through, the damaged surface of the exterior door. Try to space the drilled holes about 1″ apart from each other. Having mixed up some two-part wood hardener, put it in a squeeze bottle and fill in the 1/4″ holes. You can use a paintbrush to spread it around all the damaged spots. If you are leaving your exterior door outdoors, cover it with a garbage bag or plastic tarp.

3. Epoxy Time for Rotted Door Repair

Using an epoxy wood filler for rotted door repair can be a little toxic, so it’s best to use protective gloves on your hands as well as a face mask. A well-ventilated area is also necessary when using epoxy.

Take two separate stir sticks and label one “A” and the other “B”. Put stir stick “A” into the epoxy and stir stick “B” into the epoxy hardener. Make sure they are kept separately.

Put a small amount of epoxy resin on some scrap wood using the “A” stir stick and then an equal amount of hardener beside it with the “B” stir stick. Now use a third stir stick to mix them together on the wood. Pusing a putty knife, you want to push the filler into the drilled holes. Also fill in any other gaps with the wood filler. Allow to dry for about 5-10 hours.

4. Sand & Paint the Door Frame

Use a medium grit sandpaper to sand down the excess wood filler until it is smooth against the exterior wood door. Use a finer grit sandpaper to polish it again.

Using a wood primer, prime the door and let it dry. Then paint it to protect it from any further damage from rot, leaving it good as new!
