What’s included

  • Move or cover nearby furniture and plants
  • Power wash the deck at appropriate pressure for wood
  • Spot-treat mold or mildew with a wood brightener if needed
  • Allow the wood to dry fully before applying sealant
  • Apply one to two coats of penetrating deck sealant

How it works

1

Wash & treat

We power wash the full deck surface and apply brightener to any sections with mold or heavy weathering.

2

Dry & assess

We allow drying time — typically 24 to 48 hours — and check that the wood is ready to absorb sealant properly.

3

Seal & finish

We apply the sealant by brush or roller for even penetration, finishing all board faces and cut ends.

Problems we fix

  • Gray, weathered decking that looks old and tired
  • Mold and mildew spots particularly in shaded sections
  • Splinters from dried-out surface fibers
  • Sealant from a previous application peeling and flaking
  • Water beading poorly on boards that have soaked up previous seasons' rain

Deck Power Washing & Sealing in Columbia — FAQ

Can the washing and sealing happen the same day?

Not typically — wood needs 24 to 48 hours of drying time after washing before sealant will absorb properly. We usually schedule washing and sealing on back-to-back days or across two visits.

What type of sealant do you use?

We work with penetrating oil-based and water-based sealants. The right choice depends on your deck species and whether you want a clear or tinted finish.

How long will the sealant last?

Most quality sealants hold up well for two to four years under normal use, with exposed horizontal surfaces wearing faster than vertical railings.

My deck has old stain peeling off — can you still seal it?

We need to strip the old peeling finish first before new sealant can penetrate. Stripping adds time and cost but is necessary for a result that lasts.

Deck Power Washing & Sealing across Columbia

Columbia's long, hot, humid summers are hard on homes — HVAC strain, swollen doors, deck and fence wear, and moisture around windows and caulk are all common. Older in-town neighborhoods bring hardwood floors, plaster and original millwork, while the Northeast and the Lake Murray side add newer builds with their own needs. Our pros are comfortable with both.
