Window Cleaning

Interior and exterior window washing, screens, tracks and hard-water stain removal.

the guide

Squeegee or water-fed pole

Cleaners either hand-wash with a squeegee, which also handles interiors, or use a water-fed pole that scrubs exterior glass with purified water and leaves it to dry spot-free. Poles keep crews off ladders for upper floors; hand work reaches details poles miss.

What affects the price

The number and size of windows, divided panes, storm windows, height and access, whether interiors, screens and tracks are included, and how built-up any mineral staining is.

Ladders, insurance and your house

Window cleaning means ladders against siding and gutters and crews near landscaping. Ask how they protect both, and confirm liability coverage — and workers’ compensation if they have employees, which Pennsylvania requires of most employers.

Rules and paperwork in Pennsylvania

  • Pennsylvania does not issue a statewide license for this trade. Some municipalities register or license it locally, which is one reason to confirm requirements with your own municipality.

Sources: Pennsylvania Department of Labor & Industry. Rules change — confirm current requirements with the agency and with your municipality.

Questions to ask before you hire

  1. Do you clean by hand, with a water-fed pole, or both?
  2. Are screens, sills and tracks included?
  3. Are you insured for ladder work on my house?
  4. What is your Pennsylvania Home Improvement Contractor registration number?

Frequently asked questions

How often should windows be cleaned in my town?

Many homeowners schedule exterior cleaning once or twice a year, typically in spring after pollen season and again in fall. Homes near busy roads or under trees get dirty faster.

Can hard-water spots be removed?

Often, with specialty cleaners or polishing. Spots left for years can etch the glass permanently, so fixing the water source — usually a sprinkler hitting the window — matters as much as cleaning.

Do I need to be home?

Not for exterior-only work if the crew has access to the yard. For interiors, clear sills and move furniture away from windows before they arrive.
