Expert Window Installation and Replacement – No Shortcuts
Known as one of the top window companies in Oshawa, we use premium-grade materials, modern sealant systems, and Energy Star-rated components. Our services include:
Window Installation
We start with detailed structural measurements and install insulated vinyl or composite-framed windows using low-expansion polyurethane foam. Each Energy Star-certified window includes argon-filled glass units, multi-chambered frames, and stainless steel spacers. Every install is sealed with nail flanges, drip caps, and flashing for water protection. With Low-E and triple-pane glass options, our installations keep Oshawa homes quiet, energy-efficient, and comfortable year-round.
Window Replacement
Our window replacement service brings your home up to date without disturbing its structure. We remove the old windows and install fusion-welded frames that hold up in Canadian winters. Our upgrades include Low-E glass, argon gas, thermal edge spacers, and reinforced sashes. We re-caulk, re-trim, and re-insulate for a seamless retrofit or full-frame installation. It’s all about long-term savings and performance, without the fuss.
