Who we are

Crawl space reconditioning is the heart of the business. Everything else grew around it.

Watertight Waterproofing is owned and run by Zach Roberson. The core of the business is crawl space reconditioning, which is all of the moisture control, insulation and repair work that makes the space under a house dry and healthy again. Around it sit basement waterproofing, mold remediation and joist and beam repair, because homeowners want one crew that can handle all of it.

The technician who inspects your house is the one who explains the plan. Our people work in protective suits and respirators when the job calls for it, and they leave the site clean. And when you call, someone answers.

How we work

Four things you can hold us to

We show you, we do not tell you

Photos and video of what we find under the house, before you decide anything.

One number, in writing

A scope and a price you can read. Options where there are real options. No surprises on the invoice.

A lifetime transferable warranty

On our work. It stays with the house, which is worth real money when you sell.

Fair on price

We will beat any reputable company's price on the same scope. We would rather do the job well than pad it.

Not a marketing shoot. This is what a week looks like.
