Andrew Wynn is director of Hippo Home Care, which helps homeowners proactively care for their homes to catch issues before they become costly repairs. He joined staff writer Jura Koncius last week for the Washington Post's Home Front online chat. Here is an edited excerpt.

Q: How do you know you need a dehumidifier? Where is the best place to put it?

A: Dehumidifiers are generally good in areas where the humidity level is consistently more than 60%. This is common in basements and in humid climates.

Q: It looks as if we'll be working from home for the foreseeable future, so it seems time to turn my table into an official office space. Is this a bad time to have someone come in and assess what it would take to create some built-ins?

A: A better time than ever, in my opinion. Reputable, licensed pros are taking all of the right precautions when entering homes, and given it's summer, you can run fans and keep your windows open while they're there to keep air circulating.
