Window Cleaning
in Baltimore, MD
Crystal Clear Glass Across Baltimore
From the Ground Up
Pollen season alone coats every window in the metro area with a film thick enough to notice from the curb. The humidity rolling off the Chesapeake Bay, exhaust from the I-95 corridor, and years of mineral buildup from rain only make it worse. Rowhouses, colonials, and multi-story homes all deal with the same problem: glass that loses its clarity faster than most homeowners realize.
At Baltimore Pressure Washers, we handle exterior and interior window cleaning using a water-fed pure water pole system that keeps our crew on the ground for most residential jobs. The pole reaches up to 70 feet, covering the vast majority of homes in the area without a single ladder touching your siding. Deionized water does the cleaning and the rinsing, so nothing is left behind when it dries. No soap, no chemical residue, no streaks.
If your windows are overdue for a proper cleaning, call (443) 531-6660 or request a free quote online. We respond quickly and walk you through everything before the appointment.

Why Homeowners Trust Our Window Cleaning
No Ladders on Most Jobs
Our water-fed pole system covers most residential homes from the ground, which means less risk to your property, less disruption to your day, and faster results overall.
Pure Water, Zero Residue
We clean with deionized water that contains no minerals, no soap, and no chemical additives. It evaporates completely clean, leaving nothing behind on the glass.
Twice as Fast as Traditional Methods
A job that takes a ladder-and-squeegee crew five hours or more takes our system roughly two. That speed advantage translates directly into competitive pricing for you.

Clean Windows Make
From Setup to Final Rinse
Our 6-Step Process
1
Property Assessment and System Setup
We start by evaluating window count, height, access points, and any signs of oxidation or mineral staining. Once the scope is confirmed, the multi-filter pure water machine is connected and primed so every drop that touches your glass is fully deionized.
2
Exterior Scrub With Pure Water
The carbon fiber pole, fitted with a horse-hair brush designed for glass, is extended to the first windows. We work the brush across each surface from top to bottom while pure water continuously rinses the glass and lifts dirt, pollen, and grime from the surface.
3
Self-Finishing Rinse and Oxidation Treatment
After scrubbing, a final rinse with deionized water flows down each window and evaporates without leaving any residue. No squeegee, no towel dry. For windows showing oxidation haze or acid rain deposits on south- and east-facing sides, we apply One Restore before rinsing.
4
Screen Cleaning and Interior Sill Prep
Screens are removed at $1 per screen or by you beforehand at no charge, then cleaned on the ground. For interior jobs, we vacuum each window sill to remove loose dirt, pet hair, and debris from the track, then scrub it with a cleaning solution until the track and channel are completely clean. Furniture must be cleared from window areas before we arrive.
5
Interior Glass and Frame Detailing
We apply a cleaning solution to the glass with a scrubber, squeegee it for a streak-free finish, and wipe down each window frame by hand. Our crew works room by room at a careful pace to avoid any mess inside your home.
6
Final Walkthrough and Inspection
Before any invoice is generated, we walk the completed work with you. Every window, every sill, every frame. If something isn’t right, we address it on the spot before any payment is processed.
Window Cleaning Pricing
Exterior window cleaning is priced by time, not per window. Our hourly rate falls between $150 and $200, and a standard 35-window home typically takes about two hours. That puts most exterior-only jobs in the $300 to $400 range, though final pricing depends on a few variables.
Factors that affect your quote:
Interior window cleaning starts at a $299 minimum and scales with window count. The interior process is more involved, covering sill vacuuming, frame wipe-downs, and hand-tool glass cleaning, so most interior jobs run between two and four hours. If you’re bundling window cleaning with a house wash or deck cleaning on the same day, we offer a 5 to 10% discount per service.
Your Glass, Guaranteed
Our guarantee is simple: you inspect the finished work before we bill you. That inspect-before-bill model applies to every job, interior and exterior. If something isn't right, we fix it on the spot before any payment changes hands.
We don't attach a calendar-based warranty to window cleaning because pollen, rain, nearby construction, and pet activity all affect how quickly glass gets dirty again. What we do guarantee is that the work meets your standard before we leave the property.
Frequently Asked Questions
Do you clean windows on tall or multi-story homes?
Yes. Our water-fed pole reaches up to 70 feet from the ground, which covers most homes up to five or six stories without a ladder. For buildings up to approximately eight stories, we use hanging staging or lifts. If a job goes beyond that, we connect you with a trusted high-rise window cleaning specialist.
Do I need to remove my window screens before the appointment?
That’s up to you. You can remove them yourself at no charge, or we’ll take them out and reinstall them at $1 per screen. Either way, we clean them on the ground for a thorough result.
Do you use chemicals on the windows?
Not under standard conditions. We clean exterior windows with pure deionized water only. The one exception is One Restore, a window-safe acid we use on windows with oxidation staining or mineral deposits. That’s applied on a per-window basis at an additional charge.
Do you clean interior windows too?
Yes, and it’s a separate service. Interior cleaning starts at $299 and scales with the number of windows. The process covers sill vacuuming, sill scrubbing, frame wipe-downs, and scrubber-and-squeegee glass cleaning. You’ll need to clear furniture from the window areas before we arrive.
Should I get my windows cleaned at the same time as a house wash?
We recommend waiting to see how your windows look after the house wash first. About 85% of the time, windows come out clean enough from the rinse alone. If you do decide to add window cleaning on the same day, a 5 to 10% bundle discount applies per service.
How often should I have my windows cleaned?
That depends on your environment and preference. Most homeowners in the area go annually. Homes near construction, high-traffic roads, or with heavy tree coverage may benefit from every six months. In lower-exposure settings, every two years works just fine. You’ll know when it’s time.
What is the white haze on my windows that won't come off?
That’s usually frame oxidation bleed. Aluminum window frames, especially on south- and east-facing sides, break down from UV exposure and leave a chalky residue on the glass. Standard cleaning won’t remove it. We treat it with One Restore, a window-safe acid product, at an additional per-window charge.
Can you clean windows in cold weather?
Exterior window cleaning can be done at 37°F and above. Interior cleaning can be scheduled any time of year since we’re working inside a conditioned space.
What if I also need post-construction window cleaning?
We handle post-construction cleanup as part of our full range of services. Whether it’s construction dust, paint overspray, or general debris on the glass, we can address it.
How long will the results last?
It depends on what’s around your home. Pollen, vehicle exhaust, nearby construction, and heavy tree coverage all speed up re-soiling. We don’t push a set schedule. Most customers tell us they can see when it’s time, and that’s the right call.
