We'd rather save it — but safety comes first

We're not quick to do full replacements. If a post can be saved, we'd rather save it. Part of the job is figuring that out honestly: is this a repair that merits saving the post, or does it need to be replaced? A post is holding up a roof, so once rot has taken enough of it that the porch is losing its structural integrity, it gets replaced. Safety comes first, before anything.

Real job: five porch posts in Oakland, NJ

A homeowner in Oakland reached out about his front porch. Two or three of the posts were more than 25% rotted. He'd already tried patching some of them himself, and the patches kept failing, because nobody had fixed what was causing it.

The cause: the posts were sitting directly on the concrete, with no standoff plate underneath. Concrete holds water, and that water wicks straight up into the most exposed part of the post. It rots from the bottom out, no matter how many times you patch the outside.

We went in planning to repair the two that didn't look as bad. On closer inspection, all five had rotted the same way, and the porch was close to losing its structural integrity. So we shored the roof and swapped all five.

Why engineered columns, not pressure-treated

Years ago, pressure-treated lumber was cut from old-growth wood, and it was pretty stable. Almost everything milled today is new growth, and as it dries out it's close to guaranteed to twist, bow or crack. The yards still sell PT posts, but put one in and you'll get the callback. So for posts we go engineered.

  1. Engineered column — structurally stable; it doesn't warp and twist like pressure-treated.
  2. PVC sleeve glued over it — water can never get in and touch the column again.
  3. Factory finish — no paint required. A repair like this should last 10 to 20 years.

Porch post questions, straight answers

Why did my porch post rot at the bottom?

Usually because it's sitting directly on the concrete with no standoff plate under it. Concrete holds water, and that water wicks straight up into the bottom of the post, so it rots from the base out. Patching the outside doesn't stop it, because the cause is still there.

Can a rotted porch post be repaired, or does it have to be replaced?

Depends how far the rot has gone. We're not quick to do full replacements, and we'd rather save what we can. But a post is holding up the roof, so once the rot has taken enough that the porch is losing its structural integrity, it gets replaced. Safety comes first.

Why engineered columns instead of pressure-treated wood?

The old-growth lumber that used to get pressure-treated was stable. Today's is mostly new growth, and as it dries it's almost guaranteed to twist, bow or crack. For posts that means a callback, so we use engineered columns and glue a PVC sleeve over them.

How long does an engineered column with a PVC sleeve last?

The sleeve keeps water from ever touching the column again, and it has a factory finish, so no painting. A repair like this should last 10 to 20 years.
