Commercial Building Washing
in Delaware

Your facade says a lot about you and how you do business. A grubby exterior with dirty windows tells your clients that you don’t care about the small details. They might even wonder if you’re cutting corners, which makes commercial building washing services in Delaware so important.

But who has the time? And when you think about it, you need the right techniques and expertise to clean safely. East Coast Window Cleaning is a veteran-owned, fully licensed, and insured company with a sterling reputation. We handle everything from busy gas stations and retail storefronts to large apartment complexes and multi-story office buildings.

A proper wash doesn’t just brighten a property; it helps protect siding, paint, and other exterior finishes. Left alone, mold and algae slowly eat away at surfaces. Routine cleaning keeps a building looking sharp and prevents costly repairs.

Worried about disrupting your business? We can complete our commercial exterior cleaning in Delaware in the evenings or on the weekends for your convenience.

Surfaces and
Building Types We Wash
in Delaware

We work with all types.

Vinyl Siding and Painted Exteriors

We use a soft touch with these surfaces, relying on biodegradable cleaners and sodium hypochlorite instead of pressure. We let the solution sit for a little while and then rinse it thoroughly. We’re extra careful with darker paint colors to prevent fading and protect your landscaping by watering it beforehand.

Brick, Stucco,
and EIFS

These surfaces need more delicate handling. High pressure can damage stucco or weaken mortar, so we use soft washing only, followed by a careful rinse to prevent streaking.

Metal Panels and Commercial Storefronts

We treat metal siding, aluminum panels, and glass storefronts with a streak-free cleaning solution. We leave reflective surfaces and signage polished and spotless.

East Coast did a great job ckeaning our dryer vent. 3 years ago when they did this, they discovered our builder had not vented our dryer to the outside our our home! Thankfully we had it remedied and all is well. If you haven’t had this service done yet, please do. It’s so worth it!

Response from the owner:We are grateful for your review and pleased our service met your expectations. Your feedback is valuable to us.

I highly recommend using East Coast Window Cleaning. This past week, Jason & Noah (employees of East Coast) knocked on my door at the agreed time (a few minutes early even) and began their work. They were courteous and polite. They explained exactly what they were going to do and urged me to ask question if I had any. They made sure that when they entered my house, they put on paper booties to protect our floors. After they left, I checked each window and slider to make sure nothing was forgotten.
I do have to add that Fred (from the office) was also easy to reach by phone and also answered my questions. I felt their pricing was more than fair, and a good deal for all the work they accomplished.

Response from the owner:We appreciate you highlighting the professionalism of Jason and Noah. Your feedback on our service is valued.

We scheduled for East Coast to soft wash our house. They had quoted a fair price. From the start, they were responsive and efficient. Matt and his crew texted to let us know they were one their way so we could be ready for them. Once here the Matt and the crew were outstanding. They kept us informed of their progress and while during their work they noticed our dryer vent was clogged. They were able to clean that out for a reasonable additional fee. Matt also mentioned other things we could do, and offered to do them, but left the decision up to us. We appreciated his explanations and the fact that there was no high pressure sales push, just an explanation of potential future work. At the end of the job they asked if we wanted to do a walk around to inspect their work before they left. As it was raining, we did not do that, but thought it was professional of them to have us check out their work. We highly recommend East Coast and Matt and his crew.

Response from the owner:We're glad you found our team efficient and informative. Appreciate your review of our service.

East Coast Windows does a fabulous job. They do everything outside our house and some things inside.. They are personable, timely, and recently did a fabulous job cleaning our gutters after the big blizzard and now we’re ready for spring. They are immaculate. I recommend East Coast to anyone who wants their house to be safe and clean, and are looking for caring professionals.

Response from the owner:We're delighted to hear about your positive experience with Jayson and our team. Thank you for choosing our services!

Frequently
Asked Questions

Can you still clean my building if we don’t have exterior water access?

Yes, we can still complete the job if there’s no water access on-site. We typically ask to hook up to an exterior spigot, but if that’s not available, we’ll make arrangements to haul in water for the building washing service. Just let us know during the estimate so we can plan accordingly.

Is there any risk of your chemicals staining or damaging my dark-colored siding?

Dark-colored siding can sometimes be more sensitive to certain soft wash mixes. We adjust our chemical blend for each surface type to ensure safe, effective cleaning without streaks or discoloration. We’ve washed hundreds of buildings with dark siding and always spot-test if there’s any concern.

Do I need to be on-site while the commercial wash is being done?

You don’t need to be present during the service. Most of our commercial clients prefer to schedule building washing after hours or on weekends, and we handle everything from setup to post-cleanup independently. We’ll follow up afterward to confirm satisfaction.

How should we prep the property before your crew arrives?

We recommend clearing any loose items like signage, decorations, or equipment near the building exterior. If there are concerns about specific plants or fixtures, let us know in advance. We’ll handle cones and safety setup when we arrive.

What if it rains the day of our scheduled building wash?

Light rain usually doesn’t affect the washing process, but we’ll reschedule if weather conditions are unsafe or reduce service quality. We’ll monitor the forecast and reach out proactively if changes are needed.

How long will the building washing process take for a standard commercial property?

Most commercial building washing jobs are completed within 2 to 4 hours. Larger buildings or those with heavy buildup may take longer. We’ll give you a more accurate timeline after the initial walkthrough or estimate.

Will your soft wash chemicals damage nearby plants or landscaping?

Our team takes specific precautions to protect your landscaping during every building washing. We pre-soak all nearby plants with water, apply a neutralizer if needed, and do a full post-rinse to avoid chemical absorption. This is part of our standard process.

Do you offer recurring building washing plans for property managers or HOAs?

Yes, recurring commercial building washing is available upon request. Many of our HOA and retail clients choose scheduled services for seasonal upkeep or annual cleanings. Just mention it during your estimate and we’ll build a plan around your needs.
