Deck Cleaning in New Castle County

Deck boards across New Castle County collect mold, mildew, algae, and gray discoloration. Many lots here sit under tree cover. At T&T Powerwash we soft wash every deck, and our deck cleaning lifts all four. Bare wood gets a two-step cleaner and brightener. Composite and vinyl get a light SH (sodium hypochlorite) mix. To get the mildew and gray off your deck, call (302) 415-3285.

The Deck and Railing Types We Clean

Every deck below gets a soft wash. What changes from one to the next is the treatment, the rinse, and how many stages it takes.

Bare Wood (Cedar, Pine, Ipe, Pressure-Treated)

Bare wood gets our two-step process. We apply the cleaner, let it dwell, and rinse panel by panel at low pressure. Then the brightener goes on, and the wood changes almost instantly before a thorough final rinse. It’s the same process we use on bare-wood fences.

composite deck

Composite

Composite boards get a light SH mix that dwells and then rinses away. It’s the same care we give your siding during a house wash.

trex composite deck

Trex

Trex takes that same gentle mix. We give it time to work, then rinse the boards clean.

Vinyl Deck Photo

Vinyl

Vinyl decking is treated with the light mix as well and finished with a full rinse.

Stained Decks

A deck that already carries stain is cleaned like every other deck we handle. It gets a soft wash and never pressure.

Railings (Vinyl, Metal, Wood)

Vinyl, metal, and wood railings are cleaned right along with the deck they belong to.

Why Choose Our Deck Cleaning

A clean deck is only half the job. Here’s what you get when our crew does it.

No Pressure on Your Deck Boards

Pressure ruins bare wood and strips the finish off composite. So every deck we touch is soft washed, and the chemistry does the cleaning instead of force.

The Right Chemistry for Your Deck's Material

One approach doesn’t fit every deck. Bare wood and composite need different treatment, and matching them is how your deck comes out clean without damage.

We Tell You Upfront When a Repair Comes First

We’ll clean any deck that’s structurally sound. If boards are rotting or railings are coming loose, that’s a repair job first. We turn those jobs down to keep our crew safe, and we’ll tell you so plainly.

Every Railing Angle Checked Before We Leave

Railings have angles a quick rinse misses. We look at each one on the way out, because a deck should look right up close, not just from the yard.

How Our Deck Cleaning Works From Estimate to Walkaround

The Free Estimate From Your Address and Photos

Call, text, or fill out our form and tell us about your deck. Most residential quotes come together remotely from your address and a couple of photos you send. Every estimate is free.

One-Tap Approval and Scheduling

Your quote arrives as a link. Approve it with one tap, and we text you a couple of dates and times to choose from.

The Six Steps to Success Checklist and Our Heads-Up

About three days before we come, our Six Steps to Success prep checklist lands in your texts. A reminder follows, then a text when we’re on our way. First jobs start at 9 AM, and later slots carry a two-hour arrival window. If we’re running late, you hear it from us first.

Protecting Your Plants and Clearing the Deck

We pre-rinse the plants around the deck, and the wood itself on bare-wood decks. Anything still sitting on the boards gets moved off before treatment starts.

Treating and Rinsing the Deck

Our soft-wash system applies the treatment for your deck’s material. It dwells, and then we rinse. Bare wood adds the brightener stage on top of the cleaner.

Railings, Furniture, and the Final Walkaround

We rinse your plants again, check every railing, and put the furniture back. Then we walk the deck with you, and anything you notice gets fixed on the spot. You can pay on site or through the invoice link, and we stand behind the work after we leave.

What Deck Cleaning Costs

We price each deck by its material, its square footage, and its railings. Bare wood costs the most, and your free estimate sets the final number.

  • About $100 for a small, fairly clean deck up to $800/$900 for a bare-wood deck that needs the full two-step cleaning. The low end covers a small deck in decent shape, usually added to a house wash. The high end is bare wood that needs every stage.
  • $295 minimum per visit. Every visit carries it, so a deck booked on its own lands right at that minimum.
  • Most decks ride along with a house wash, and one trip costs far less than paying the visit minimum twice.
  • When our schedule slows down, combos that pair your deck with another service can run about 10% off. Ask when you get your estimate.
  • Setting your cleanings on a 6- or 12-month schedule earns a discount as well, so mention it when we quote.

Our Promise If Something Isn't Right With Your Deck Cleaning

If something isn't right, tell us on the day or three days later. We'll come back out, look at it with you, and make it right where cleaning can. Most touch-ups get handled before we pack up. If you spot something after we've gone, a return trip is simply part of the job.

They did a great job, they were professional and super nice. They got rid of a bees nest for me and even came back later that day to help me with a circuit breaker that went off. I will continue to use their services.

They showed up right on time. The supervisor and my husband walked around the outside of the house to discuss potential problem areas while the rest of the crew got set up. They immediately got to work and were very efficient. When the job was complete, we walked around the house again and found they even cleaned our pergola, which we weren’t expecting! Very satisfied with the professionalism of the crew and the quality of work. We would definitely recommend T and T Powerwashing and plan on using them every year.

We love this company. The young men are really friendly and they do an excellent job! My house looks so much better. My roof, that they did a couple of years ago, still looks great. Highly recommend them for all of your power washing needs. 6-10-26 update. Had my concrete pool deck and pool fence power washed today. They both look amazing. My thanks to T&T Powerwash! They look great.

Frequently Asked Questions

Most deck cleanings take between 30 minutes and 3 hours. The material and the size of the deck set the time. A bare-wood deck that needs the full two-step process sits at the long end, while a small composite or vinyl deck goes much faster.

Yes, please move light furniture, décor, and small items off the deck before we arrive. It’s all on the Six Steps to Success checklist we text you ahead of the visit. We’ll move heavy pieces like a grill ourselves, and if there’s a lot to move, expect a fee of about $75. Everything goes back where it was when we finish.
