Window replacement questions, answered
Short answers for Philadelphia homeowners.
Who runs this site?
It is an information and referral site that connects homeowners with a local window installer. It is not a contractor.
Do replacement windows require a permit in Philadelphia?
The answer depends on the scope. Confirm with L&I, and with the Historical Commission if the property is on the Philadelphia Register of Historic Places.
What should a written estimate include?
Product name and model, glass package, size of each opening, trim and finish work, disposal, permits, lead-safe work if needed, payment schedule and warranty terms.
How do I check a contractor?
In Pennsylvania, ask for the home improvement contractor registration number and check it with the Attorney General's office. Ask for proof of insurance, and get a written contract.
What about lead paint?
In houses built before 1978, replacement can disturb lead paint. EPA's Renovation, Repair and Painting rule requires certified firms with lead-safe practices.
What if my property is in a historic district?
Contact the Philadelphia Historical Commission before you order windows, because street-facing windows can be reviewed.
Will installers call me?
They may. We cannot promise a response time or availability.
Where do I start?
Read the planning guides and then send a request on the contact page.
