Learn moreCapital Wash & Seal runs two kinds of work: pressure and soft washing that lifts years of dirt, algae, and grime off a surface, and sealing that protects the surface once it is clean. Most projects only need one or the other, but concrete, interlock, and wood surfaces are often cleaned and sealed together in the same visit, which saves a second appointment and a second setup.
If you are not sure which service applies to your project, the short version is this: driveways and patios usually start with cleaning, then sealing if the surface is bare or the old sealer has worn thin; siding, roofs, and fences are almost always cleaning only; and decks nearly always need both, since bare wood left unsealed after cleaning weathers fast. Every quote below is written in plain language and priced after a look at your specific surface, not off a generic price list.
Frequently asked questions
I'm not sure which service my project needs. Can you help me figure it out?
Yes, that's normal. Tell us what the surface is and what's bothering you about it – staining, fading, weeds in the joints, a slippery patch – and we'll recommend the right service, or combination of services, in your quote.
Can you combine two services, like cleaning and sealing, into one visit?
Yes, and for most surfaces we recommend it. Cleaning and sealing a driveway, patio, or deck in the same visit means one setup, one appointment, and a sealer applied to a properly prepped surface.
Do you offer any discount for booking multiple services at once?
Bundled jobs are quoted together, and because we're already on site with equipment set up, combining services is typically more cost-effective than booking them separately on different days.
How do I know if I need cleaning only, or cleaning plus sealing?
If the surface still has a visible sealer sheen and just looks dirty, cleaning alone usually does it. If the surface looks dry, chalky, or the sealer was applied more than two or three years ago, it's due for both.
Do all of these services come with a written quote before work starts?
Yes, every service we list includes a free, written quote based on your specific surface and its condition, so there are no surprises once the crew arrives.
Do you offer any recurring or seasonal service plans?
Yes, surfaces like walkways, siding, and driveways that see moss, algae, or salt buildup year after year can be set up on a recurring seasonal visit, so you're not starting from scratch each time.
