Homes near Silver Lake’s waterfront deal with steady humidity and geese, and both leave their mark on the siding and walks nearby. The damp air coats vinyl siding in a film of algae, dirt, and mildew, and the geese leave their own mess across the walkways. Here in Dover, our team at T&T Powerwash takes care of both. We clear the film off the siding and clean the walks on houses and storefronts across town. Whether you’re downtown, up in The Hamlet, or down in Woodbrook, call us at (302) 415-3285 and we’ll get your siding and walks clean again.
Most of what we clean in Dover is homes, with a steady commercial side. The crew standards stay the same on both. What changes is the scheduling and the access.
Subdivisions like Clearview Meadow are mostly vinyl-sided houses and townhomes, and downtown has its rows of brick townhouses. Siding of every kind gets a soft wash from us, never pressure.
Most homes and most concrete do well with one cleaning a year, and spring is when a lot of Dover homeowners book it.
Along Route 13 (DuPont Highway), we can take on properties such as storefronts and strip retail. Restaurants, apartment complexes, HOA common areas, and new builds fit too.
Commercial jobs start with a site walk and a talk about budget, so the dirtiest areas go first. You get a line-item quote, a COI and W-9 on request, and an invoice when we finish, with net 30 accepted.
Two things set our work apart, one for homes and one for businesses.
Our cleaning agent is SH (sodium hypochlorite), and we let that chemistry do the work instead of cranking up the pressure. On roofs, we bag the gutters and rinse the shingles afterward, the way ARMA guidelines call for. Plenty of crews will spray SH on a roof and drive off. For us, the real job is making sure your landscaping comes through alive. Your siding ends up with no pressure marks, and nothing stays on the shingles to wash into your beds at the next rain.
Restaurants, drive-throughs, storefronts, and parking lots get cleaned overnight, from late evening into the early morning, working around your traffic. You never have to close to get clean, so your revenue stays protected. Not many companies our size take on night work.
A house wash is the job we’re booked for most, and nearly all our residential work runs through the same six steps.
Call, text, or fill out the form. We price most homes remotely from the address, street view, or a couple of photos you text us. Pavers, complex roofs, and commercial sites get an in-person walk. Your quote arrives as a Housecall Pro link you approve with one tap, and we text you a couple of dates to pick from.
About three days out, we text you our Six Steps to Success checklist. Move small items, latch the windows, switch off outdoor lights, and turn the spigots on. Leave heavy things like a grill to us. A reminder follows, then an on-the-way text. First jobs start at 9 AM; later visits get a two-hour window.
Our lead technician walks the property for problem areas, with you or around your day. The second technician hooks up to your spigots (two is ideal) and checks every window is shut. A whole house wash uses about $10 of water.
We pre-rinse your plants and landscaping first. Then our soft-wash system applies a mild mix of SH and surfactant to the siding, windows, and trim. We let it sit long enough to break down the growth and grime. On the vinyl-sided homes in The Hamlet and Woodbrook, the treatment does the cleaning and the siding never sees pressure.
We rinse the siding, windows, and trim thoroughly. Your plants get rinsed again and treated with our plant neutralizer. Most homes take 45 minutes to two hours from start to finish.
We walk the property with you at the end, and anything you notice gets handled on the spot. Pay on site or through the invoice link, and expect a check-in down the road about your next cleaning.
We price each job by its size, the number of stories, the surface, and how easy it is to reach. Most homes get quoted remotely, and commercial sites get a site walk first. Every visit carries a minimum, so bundling a few things into one trip costs less than spreading them out.

|---|---|---|
| Visit Minimum | $295 minimum per visit | Applies to any visit, so small jobs cost far less added to a house wash |

| Exterior Cleaning for HOAs | Neighborhood group rates run about 30% off standard individual pricing | Ten-home minimum, with a little more off for 55+ communities; two or three neighbors booking the same day get a smaller group discount; HOA-wide contracts run 30 to 40% off per-home pricing |
| Other Commercial Services | Custom quote | Building Washing: Custom quote after a site walk, priced on size, height, lift needs, and tenant coordination, with night and rush work costing more. Parking Lot Cleaning: Custom quote by square footage and lot type, with greasy lots costing more. Exterior Cleaning for Apartment Complexes: Priced per building, with volume pricing for multi-building properties. |
Bundling always wins, since one visit beats the minimum on separate trips. A roof cleaning booked with a house wash saves about 10%, or $150 to $200. Customers on a set 6- or 12-month schedule get a recurring-schedule discount, and every roof cleaning comes with a free gutter inspection.
Here’s what we promise, service by service.
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. Stubborn stains get an honest explanation, never a promise we can’t keep.
If we clean your roof, it stays clean for two years, asphalt, cedar, tile, or metal. That’s our guarantee. Most roofs actually stay clean four to five years.
Your panels come out spot-free, guaranteed. Pure deionized water, a soft boar’s-hair brush, nothing else.
We test a spot first. If our strongest rust remover can’t make a difference, we don’t charge you for the rust removal.
We back our graffiti removal with a satisfaction guarantee. Most graffiti comes off completely on nearly every job. If someone else’s pressure washing already scarred the surface, we’ll say so upfront.
Awnings come out clean without affecting the look or color of the fabric. Torn fabric gets cleaned around, never put under pressure.
We guarantee the area will be ready for use when we’re done, dust, dirt, mud, and debris cleared. Paint on blacktop or heavy paint on glass needs more than cleaning.
As the state capital, Dover has a civic core the towns around it don’t, with brick government buildings, churches, and townhouses packed into the downtown blocks. We treat every property here like it belongs to a neighbor. From the capitol district out to the DuPont Highway, these are the places that give Dover its shape:
Our work takes us from the downtown townhouses and Overlook on Silver Lake out to The Hamlet, Woodbrook, and Clearview Meadow.
Every estimate is free, and we get it back to you quickly. Give us a ring at (302) 415-3285, Monday through Friday between 8:00 AM and 4:00 PM. Whether it’s a townhouse near The Green or a storefront on Route 13, tell us what needs cleaning and we’ll put a number on it.
