The Ranking
Our top 10 window companies in Edmonton
Edmonton homes ask a lot of their windows. Winters run long and cold, with stretches far below freezing, and summer sun hits south and west glass hard. Much of the housing stock dates from the postwar bungalows through the 1970s and 1980s, with plenty of older frames still holding original single or early double glazing. Replacing them is one of the more visible ways to cut heating bills, and it is also where a bad installation shows up first as drafts, fogged units and frost on the inside of the glass.
Start with the rating labels. Look for Energy Star certification for Canada's northern zone and ask for the NFRC or CSA A440 performance numbers on the quote, including U-factor and the glass package. Triple pane is common in Edmonton, but a good double pane with a warm-edge spacer can be enough for some budgets, so ask for both prices. Vinyl, uPVC and fibreglass frames each behave differently in cold swings, and the companies below carry different mixes.
On permits, check with the City of Edmonton before work starts, particularly if the opening size or structure changes. Homes built before 1978 may have lead-based paint on old wood frames. Health Canada guidance says to avoid sanding or scraping old paint, so ask any installer how they handle demolition dust and disposal.
On licensing, Alberta does not issue a provincial licence for window and door replacement, so there is no state-style licence number to look up. Instead, ask each company for proof of liability insurance and Workers' Compensation Board coverage, confirm its City of Edmonton business licence, and get the warranty in writing. Rebates and financing, including the City of Edmonton Clean Energy Improvement Program and the provincial Seniors Home Adaptation and Repair Program, can change the real cost, so ask who handles the paperwork.
