Here's what I can do for your home.
Outside Window Cleaning: This is the cheapest and simplest deal. The outside of the window gets cleaned, then the frame gets wiped down to remove any excess solution.
Inside and Outside Window Cleaning: This is the most popular. It includes the outside of the window but the inside of the window gets cleaned as well.
In and Out with Tracts and Sills: This is the best deal. It includes everything mentioned before, but I open the window and clean the tracts and scrub the bottom sill.
For your business, it's important to keep your windows cleaned on a regular basis. Most storefronts get their windows cleaned every 2 weeks. For larger commercial buildings, I'm limited to 4 story buildings at the moment. Call 724-472-7000
