Welcome to WOW! Window Cleaning by Len Oniskey.

We have been cleaning windows in the Bucks County area since 1992 the old fashioned way - with squeegees and mild detergent to ensure a high-quality finish without harm. We serve over 2,000 residential and commercial customers each year. Fully insured, we are available annually, monthly or weekly. Whatever you need, we can help.

We service Central and Upper Bucks County, Montgomery County, the Main Line, Southern Lehigh County and Northampton County in Pennsylvania. In New Jersey we service Mercer, Hunterdon, Sommerset County and Warren County. We also service the Jersey Shore in July and August.
