"Had a new front door and sidelights installed. The install team was meticulous — properly foam-insulated, perfectly caulked, and they even touched up the interior trim paint. Looks amazing."

Common Questions

Frequently Asked Questions

Most window replacements are completed in a single day. A typical whole-home replacement of 10–15 windows takes 1–2 days depending on the styles and any unforeseen framing issues. We aim to have your home fully weather-tight by the end of each work day, so you're never left with open openings overnight.
Yes — always. We provide a detailed written quote that itemizes every product, service, and cost before any work begins. We do not start a project without your written approval of the quote. There are no surprise charges; if something unexpected comes up mid-project, we discuss it with you before proceeding.
We carry a selection of Canadian-made and Canadian-certified vinyl windows and fibreglass/steel entry door systems — all rated for our climate zone. We're happy to discuss specific product lines during your in-home consultation. Our focus is on ER (Energy Rating) performance appropriate for Zone 6/7 Alberta conditions, not on promoting a single brand.
Yes. We offer ENERGY STAR Most Efficient certified windows and doors for homeowners who want to maximize energy savings or qualify for government rebate programs. ENERGY STAR products for Zone 3 (Alberta) must meet strict ER and U-factor thresholds — we'll let you know which options qualify during your quote visit.
For renovation projects that require a building permit (basement developments, structural changes, additions, etc.) we manage the permit application process as part of the project. Permit costs are included in your quote. For window and door replacements, permits are generally not required, but we verify local requirements for your specific municipality.
Every project comes with two layers of protection: the manufacturer's warranty on the products themselves (typically 20–25 years on sealed window units, lifetime on frames and hardware) and our workmanship warranty covering the installation. If anything related to our installation fails, we come back and fix it — no argument, no charge. Warranty documentation is provided in writing at project completion.
