We compared 17 window companies in Philadelphia on Google Maps · 5 listed · How we rank

Many Philadelphia rowhomes are more than 100 years old, so replacing their windows often means fitting new units into old brickwork. The window companies in Philadelphia below hold more than 3,200 Google reviews between them, and none is rated below 4.8, which makes the real decision about the kind of window and the kind of house rather than who has good marks.

Short answer: ARDMOR Windows & Doors, based in Willow Grove, carries the most Google reviews on this page, 4.8 stars from more than 1,400 reviews. Thermal Quality Window & Door Company (4.9, Broomall), Smart Shield Windows (5.0, a service-area business) and Emerald Windows (4.9, North Philadelphia) are all rated higher, with Emerald the one whose site and reviews focus on historic and custom windows.

How the scorecards are built

Every number on this page comes from public Google data on the date shown. Rating is the live Google star average. Review volume is how many customers have rated the company. Confidence weighs the rating by that volume, so a 4.8 from over a thousand people carries more weight than a 5.0 from a dozen. Recency shows how recently people are still leaving reviews. No business can pay to change these numbers.

What changes the price of new windows

We aren’t listing dollar figures because neither the reviews nor the company sites on this page give them. Price per window moves with the frame material (vinyl, wood or aluminum), the glass package, the size and shape of the opening, and whether an old frame or surrounding trim has to be repaired. Windows in a historic district may be limited to certain styles. One reviewer said a picture window came in thousands below other quotes, so collect several estimates and compare what each one includes.

Where these window companies work

Emerald Windows has a North Philadelphia address, while ARDMOR (Willow Grove), Window World of Philadelphia (Horsham) and Thermal Quality (Broomall) serve the city from the suburbs. Smart Shield Windows travels to customers across Bucks County and nearby areas. Need windows near me? Each listing shows a phone number and a map link so you can check the closest option.

Questions to ask before ordering windows

  • Is the quote itemized by window, and does it include removal of the old units and trim work?
  • What warranty covers the frame, the glass and the installation, and who handles a failed seal?
  • How many weeks pass between measuring and installation?
  • Will the crew work around the plaster, brick or stucco around my openings?
  • If I live in a historic district, will you handle matching styles and any approvals?
  • Who exactly will install, an employee crew or a subcontractor?
