Fixed Casement Windows
Fixed casement windows are an excellent choice for homeowners who want to add style and elegance to their spaces. They look like traditional casement windows with a sash, but the sash is fixed and does not open, offering a sleek, uninterrupted view.
Structurally sound and designed for durability, fixed casement windows are often combined with operable casement or awning windows to create functional and visually appealing window arrangements. With superior airtightness and double or triple-glazed sealed units, they provide energy efficiency, low maintenance, and a timeless addition to any home.

The Installer Who Became the Owner
Before I started Perla, I spent years physically installing windows and doors for large companies across the GTA. I was the one on the ladder. I was the one cutting the frame, sealing the edges, making sure it was level and tight. And I saw things that bothered me. Rushed jobs. Gaps left unsealed. Installers told to finish faster so the company could book the next sale. Homeowners paying premium prices for work that would fail in 3 years — and nobody would be accountable. That’s why I started Perla. When you hire me, you’re not getting a salesperson who hands your job to a stranger. You’re getting the owner — someone who has done this with his own hands, who knows every mistake that gets made, and who won’t let it happen on your home. Every window I install, I ask myself one question: would I accept this in my own house? If the answer is no — we fix it before we leave. — Denys Diachenko, Founder & Installer
