Preventive Maintenance

Using Contractors

The how-to-do-it information here also is useful for homeowners who use a contractor for column repair.

Dealing with contractors is much more successful when you know what needs to be done and how it should be done, even if you cannot do it.

One problem: a contractor may tell you repair is impossible, because he does not know how to do it!

Another problem: a contractor may tell you he knows how to fix columns, when in fact he does not. The danger is that he will do something incorrect.

Knowledge is Power.

Moisture is the main concern. Columns deteriorate when moisture gets trapped inside and cannot evaporate away.

Bases often are the first element to begin to rot. Be sure that water drains away from column bases and does not pool around them.

Keeping columns dry is the principal goal of preventive maintenance.

Caulk at all joints and seams to keep water out. But don't plug vent holes!

Paint. A solid paint film also keeps water out. However, two issues arise about paint.

  1. Heavy build up of paint inhibits moisture from passing through the paint film and escaping from the column.
  2. Some kinds of paint are more permeable to escaping water vapor. Marine paints even blocks moisture escape entirely.

Water vapor is amazing. It can pass through walls, plaster, paint, and wood.

Vent. Hollow columns usually vent out the top into the building framing. If necessary, air vents can be added to columns to let air circulate and evaporate away any moisture inside.
