How to fix wood rot on porch

Yes, unfortunately the cost of many building materials has gone up this much in the last while.

Could you post a picture of the rotting portion so that we can the extent of the damage, and how the damaged areas relate to the rest of the porch structure?

Can you replace the rotted boards with pressure treated?

The best thing is to replace the rotten wood. Since it's a floor, this is a safety issue.

It needs replacing, use pressure treated lumber, until then use a large piece of plywood to cover the damaged part to prevent injury. It will be a difference in height so you may want to place a rug over the lip where the plywood is to smooth the transition, or paint the edge a bright color to draw attention to it.

Hi Toye,

Cut out the Rot and replace with New Timber or fill with wood filler if small amount. Use Preservative.

See if you can find a sawmill and purchase wood directly from them. It won't be pressure treated but the amount you will save, you can purchase the solution and seal it yourself. We just bought 2x6x12 $6 each, compared to $20 for plain spruce fir boards at the local retailer.

You can apply wood hardener, apply filler, then sand it down, prime, and paint them.

Thanks for all the answers, anyone else have any input?

Hello. Are you looking for a structural or cosmetic repair? In areas where we’ve had doorway weather induced rot we have replaced small sections of this rotted wood with scrap custom cut pieces pressure-treated wood caulked and repainted.

If it’s a small cosmetic repair only—-an epoxy putty might be considered.

Try scraping out the rotten parts, then use a wood hardener. After that you can fill it with an outdoor putty or something like Bondo. All told, those would run you about $20.

Lowes sells a product called rock hard putty and the stuff if pretty amazing. You can mold it before it dries. You can sand it after it dries and you can prime and paint over it.

A large can is around $10 at Lowes.
