Choose your level of clean
Whether your windows need routine upkeep or a first-time deep restoration, we match the level of clean to your space - safely, thoroughly, and without disruption.
Maintenance clean (regular)
Ideal for quarterly or biannual upkeep. We clean glass, frames, tracks, and sills to prevent buildup and maintain long-term clarity.
Deep restoration clean (first time)
Includes razor-blade removal of old paint overspray, tree sap, and heavy oxidation. Intensive deep scrubbing of blackened tracks and sills to restore original color.
Post-construction
A delicate operation requiring precision. We remove cement, silicone residue, and plaster dust using specialized solvents and non-abrasive techniques. We also safely remove stickers and adhesive residue.
Screen & fixture care
We remove your dirty screens, scrub them with "Screen Magic" solution (or wash them outdoors), dry them, and reinstall.
We also hand-clean chandeliers and hard-to-reach areas with heavy dust buildup.
The "white-glove" protocol
What happens inside your apartment during a visit.
MOST OF THE WORK HAPPENS INSIDE
In an apartment we tilt sashes in, reach past window guards and work over hardwood and radiators. The steps below are the same on every visit.
OUR 3-STEP PROTECTION PROCESS:
- Step 1
Preparation:
Before a bucket enters your home, we lay down surgical-grade drop cloths and apply protective tape to sensitive areas if needed.
- Step 2
The Wash:
We use biodegradable, pH-neutral soaps and micro-abrasive scrubbers that remove city grime without scratching tempered glass.
- Step 3
The Finish:
We hand-dry every edge, wipe the sills, and ensure no drips are left behind.

Tools & standards
We don't use cheap chemicals or dirty rags. Every tool in our kit, from biodegradable soaps to fresh rubber blades, is selected to protect your property and ensure a scratch-free finish.
Biodegradable solutions
We use Unger™ and Titan™ professional soaps that cut through grease but are safe for pets, kids, and expensive landscaping.
Fresh rubber only
Old squeegees scratch glass. We swap our rubber blades daily to ensure a perfect glide and zero micro-abrasions on your windows.
Ladder hygiene
Our ladders are equipped with rubber “socks” (stand-offs) so they never chip your interior paint or dent your exterior siding.
Deionized purity
For exteriors, we use purified water technology (WFP) that dries spot-free without chemicals, keeping your plants safe.

Apartment window cleaning questions
-
How much does residential window cleaning cost in NYC?
Residential window cleaning pricing depends on window count, accessibility, and property type:
Property Type Price Per Window Typical Total Studio/1-BR Apartment (6-10 windows) $12-$20 $120-$200 2-3 BR Apartment (12-20 windows) $10-$18 $180-$360 Brownstone/Townhouse (20-40 windows) $15-$30 $450-$900 Single-Family House (25-50 windows) $12-$25 $400-$1,000 High-Rise Condo (10-15 windows) $15-$25 $200-$375 Variables include storm windows, safety guards, window size, and access complexity. Most residential window washing services charge per window (both sides), not per pane. We provide free phone estimates – just count your windows or send photos for an exact quote.
-
Is professional window cleaning worth it for an apartment?
The inside glass most people can do themselves. The outside is the problem: in most NYC apartments it means reaching out of the window, and windows that don’t tilt in can’t be reached from inside at all. A typical 2-bedroom takes our crew about 90 minutes, tracks and sills included.
-
Who is responsible for cleaning apartment windows - tenant or landlord?
It depends on the lease. Many NYC leases leave windows that can be cleaned from inside to the tenant, and exterior work that needs lifts or rope access to the building. If you rent, check the lease or ask the managing agent before booking exterior cleaning.
-
How do you clean windows in a high-rise apartment?
If the sash tilts in, we clean both sides from inside the apartment. If it doesn’t, the outside needs access from the exterior, and in many buildings management arranges that for the whole facade. Tell us about window guards when you book: they change how a window can be cleaned.
-
Do I need my building's approval?
Most co-op and condo managing agents want a certificate of insurance before any contractor comes in, often naming the building and the management company as additional insureds. We send it before the visit. Some buildings also limit contractor hours or require the service elevator, so mention that when you book.
-
How often should residential windows be cleaned?
Twice yearly – spring and fall – is the baseline for NYC homes. Spring cleaning removes winter salt and pollution. Fall service clears summer dust before heating season. Increase to quarterly if you’re near heavy traffic, ground-level, or have construction nearby.
-
Can you clean windows without me being home?
For existing clients – yes, with arrangements (building super, lockbox, household staff, smart locks). New clients must be present for first service so we can document window conditions and verify professionalism. We require someone 18+ on premises if children or pets are home for safety. Ideal arrangement: be present first 15 minutes for walkthrough, then leave. Return for final inspection. This balances your schedule with quality service delivery.
