Getting Algae and Mildew Off New Castle County Siding

House Washing in New Castle County

Algae, dirt, and mildew on your siding are what our house washing at T&T Powerwash takes off. Summers in New Castle County run humid. We soft wash the siding with a mild SH (sodium hypochlorite) and surfactant treatment. Then we rinse everything down, your plants included. To get your siding looking clean again, call (302) 415-3285.

The Siding Types We Clean, Matched to the Material

Every home gets a wash built around what it’s made of. Some materials need a stronger mix, and we adjust before the treatment ever goes on.

Vinyl Siding

Vinyl Siding

Vinyl on single- and two-story homes is the house wash we do most often in the area. It gets our mild downstream mix, time to dwell, and a thorough rinse.

Hardie board fiber cement siding

Hardie Board / Fiber Cement

Hardie board and fiber cement get a treatment mixed for the material. From there it’s the same routine as vinyl: apply, let it dwell, rinse.

Brick

Brick is soft washed with a process matched to masonry. The treatment handles the cleaning, so the pressure stays low.

Stucco

Stucco

Stucco takes a stronger mix than vinyl. A large stucco home with heavy buildup costs more to wash, and we’ll say so at the estimate.

Wood Siding

Wood siding gets a soft wash matched to wood. The chemistry does the work instead of force on the boards.

Metal Siding

Metal siding is soft washed too, with a mix set for metal.

Chalky, Oxidized Vinyl Needs a Different Cleaning

Oxidized siding, that chalky film on older vinyl, needs a different process than a standard house wash, so it's priced separately. It's also the surface most often damaged by high pressure, which is exactly why we soft wash.

Earlier pressure washing tends to make oxidation worse. We regularly get called out to fix pressure marks another crew left behind on oxidized siding. If your vinyl has that chalky film, mention it when you reach out. We'll look at it and price that cleaning at your estimate.

Why Homeowners Choose Our No-Mark House Washing

Here’s what sets a house wash from us apart.

No Pressure on Your Siding

Our soft wash keeps the pressure low and lets the treatment do the cleaning. That’s why a house wash from us never leaves marks on your siding, no matter what the house is made of.

Plant Protection Comes Standard

Your beds and shrubs are part of every house wash, not an upgrade you pay extra for. We protect them by pre-rinsing, diluting, and neutralizing rather than throwing covers over them.

You Hear From Us Before Every Step

Two words come up in our Google reviews more than any others: responsiveness and communication. We answer the phone, we text you a quote you can approve in one tap, you get a prep checklist before we come and a heads-up when we’re on our way, and if we’re running late, you’ll hear it from us first.

On a wash day, that means you’re never left guessing about when the truck pulls up.

How Our House Washing Goes From First Call to Walkaround

A Free Estimate From Your Address and a Few Photos

Call, text, or fill out our form and tell us about the house. We pull it up on satellite and street view, or you text us a couple of pictures. Simple jobs get a price right on the call, and the estimate never costs a thing.

One-Tap Approval and Texted Dates

Your quote shows up as a link. Approve it, and we send a couple of dates and times to choose from.

Your Prep Checklist and the Heads-Up

A few days before we come, you’ll get our short prep checklist, mostly moving small items and closing windows. We’ll handle anything heavy. And because there’s a minimum for any visit, adding the walkway or fence to your house wash costs far less than calling us back for it later.

That checklist is our Six Steps to Success, and it lands about three days out. A reminder follows, then a text once the crew is rolling. First jobs start at 9 AM, and later slots get a two-hour arrival window.

Walking the House and Setting Up

Our lead technician walks the property looking for problem areas, with you if you’re home. Meanwhile, our second technician hooks up to your water and checks that every window is shut tight.

Pre-Rinse, Treat, and Rinse Down

We pre-rinse your plants and landscaping first. Then our soft-wash system applies the mild SH and surfactant mix to the siding, windows, and trim, and we give it time to dwell. Afterward everything gets a thorough rinse, including your plants a second time. Plant neutralizer goes on to finish protecting them.

Final Walkaround and Wrap Up

We close with a walkaround of the house, and anything you point out gets handled before we leave. You can pay on site or through the invoice link. A review request follows, and later on, a check-in about your next cleaning.

What a House Washing Costs, From Stories to Siding Type

Every house wash is priced for the specific home. Size and siding move the number most, and you get the exact figure with your free estimate.

  • Most house washes land between $350 and $600. Where yours falls depends on how many stories the home has and its footprint. Stucco runs higher than vinyl, and dormers that need ladder work add time. Townhomes cost a bit more because of the long hose runs through neighboring units. Rust removal, degreasing, and oxidized siding are priced on top.
  • $295 minimum per visit. It applies to any trip we make, so small add-ons make the most sense on the same day as your wash.
  • Roof cleaning booked with your house wash saves about 10%, or roughly $150 to $200.
  • Off-season combos: pairing two services in one visit, like a house wash and the sidewalk, sometimes runs about 10% off. Ask when you get your estimate.
  • Two or three neighbors booking the same day get a group discount.
  • A set 6- or 12-month schedule earns a discount on each cleaning.

Our Promise to Come Back and Make Your House Wash Right

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 happen during the final walkaround while we're still in your driveway. If something catches your eye after we've gone, a return trip isn't a question.

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

Yes, a soft wash gets your house clean because the treatment breaks down the growth and grime on the siding. Pressure isn’t what does the cleaning. The result also holds up longer than a pressure wash would.

A house wash takes 30 to 45 minutes on a small single-story home and about two hours on a two-story. It only runs past two hours when you add other services to the same visit.

No, we don’t wash mobile or trailer homes. They can’t give us enough water flow, and the wash carries a real risk of leaks.

Yes, we hook up to your outdoor spigots. Two working spigots is ideal, so let us know ahead of time if you only have one. A whole house wash uses about $10 of water. Please make sure the spigots are turned on before we arrive.
