We install with the same precision flashing standards we bring to roofing and siding, because these systems only work together. Whether you're replacing aging windows as part of a full exterior renovation or installing a statement entry door, the install sequencing with your siding and roofing determines how well the whole envelope performs. - High-performance, energy-efficient glazing - Precision flashing and weatherproof sealing - Custom sizing for renovations and new builds [Request a Quote →](https://www.stoikexteriors.ca/pages/contact) [See Our Work →](https://facebook.com/stoikexteriors) Under the Surface ## Every Window, *Installed to Shed Water* A window is only as good as the opening it's set into.

FAQ ## Common *Questions* Why is flashing detail so important around windows and doors? Windows and doors interrupt your exterior envelope, so the flashing and sealing detail is the difference between a tight building envelope and a slow, hidden water problem. We install with the same precision flashing standards we use for roofing and siding. Should windows and doors be installed with siding or roofing work? Sequencing your window and door install with your siding and roofing determines how well the whole envelope performs, so we coordinate these together whenever a project includes more than one. Do you install energy-efficient windows? Yes, we install high-performance, energy-efficient glazing suited to Alberta's temperature swings. Can you custom size windows and doors for a renovation? Yes, we handle custom sizing for both renovations and new builds, including statement entry doors.
