Caulk and weather sealing in Houston

Caulk and weather sealing in Houston keeps water out and cool air in. We remove old caulk, clean the joint and apply fresh sealant at tubs, showers, windows and doors. It is a small job with a big payoff on your power bill and your walls.

  • Black or pink mold along a tub or shower seam
  • Caulk that is cracked, peeling or missing
  • Daylight around an exterior door
  • A draft near windows in winter
  • AC running longer than usual
  • Water stains under a sink or around a tub
  • A door sweep that no longer touches the floor

Good to know in Houston

Houston air stays humid most of the year, so tubs and showers grow mold on weak caulk fast. A sealed door and window set also helps the AC, which runs hard from May through September.

Questions about caulk and weather sealing

How long does caulk last?

Quality silicone in a bath often lasts several years. In a humid house, check it each year.

Can you fix mold in the caulk line?

We remove moldy caulk and replace it. If mold has spread behind the wall, we tell you and suggest a specialist.

How long before I can shower?

Most silicone needs 12 to 24 hours to cure. We tell you the exact time for the product we use.

Will this lower my power bill?

Sealing leaks helps. The amount depends on how leaky the house was.
