When to Replace Your Windows
Windows typically last 20-30 years, but performance declines well before total failure. Signs that replacement is overdue include visible condensation between glass panes (indicating seal failure), drafts near closed windows, difficulty opening or closing windows, visible rot in wood frames, and rising energy bills. In the Lower Mainland, failed window seals also create moisture pathways into the wall cavity, compounding the damage beyond the window itself. Tomron Construction provides honest assessments, we will tell you which windows need immediate replacement and which can wait.
Our Window Installation Approach
We install windows to perform flawlessly for decades in the Lower Mainland climate. That means meticulous attention to the flashing and sealing details that most installers rush through. Every window opening is properly prepared with head flashing, sill pan flashing, and flexible membrane at the jambs before the new window is set. We test-fit, level, shim, and secure each window, then complete the exterior trim and interior finishing. If your window replacement is part of a larger siding or envelope project, we sequence the installation to ensure perfect integration with the surrounding wall assembly.
Window-to-Door Conversions
Want to open up your living space with a new patio door or garden entrance where a window currently sits? Tomron Construction handles window-to-door conversions that require structural modification, including header installation, framing adjustments, and proper integration with your home's exterior. The result is a seamless transition that looks like the door was always part of the original design.
Energy Efficiency and Glass Performance
Modern windows are engineered for energy performance. Double-pane glass with argon gas fill and low-E coatings is the standard for new installations, blocking heat loss in winter and solar heat gain in summer. Triple-pane glass takes performance further, delivering R-values up to R-8 and significant noise reduction. The glass sealed unit is just as important as the frame: we work with Vitrum Glass, Western Canada's largest glass fabricator, to ensure every sealed unit meets the highest performance standards. During your consultation, we help you choose the right glass package for your home's orientation, climate exposure, and energy goals.
Rebates and Savings
Window replacement is one of the most eligible upgrades for BC and federal energy rebate programs. CleanBC, Canada Greener Homes, and utility-specific programs from FortisBC and BC Hydro offer rebates that can significantly reduce your project cost when you install qualifying energy-efficient windows. Tomron Construction is experienced with the rebate application process and can help you understand what you qualify for before you commit.

A single window replacement typically takes a few hours. A whole-house window replacement can take 2-5 days depending on the number of windows, accessibility, and whether the frames require modification.
Retrofit (or insert) installation fits a new window into the existing frame, which is faster and less disruptive. Full-frame replacement removes the entire window assembly down to the rough opening, allowing inspection and repair of the surrounding structure. We recommend full-frame when there is evidence of moisture damage or when new siding is being installed.
Yes. Modern double or triple-pane windows with low-E coatings can reduce heat loss through windows by 30-50% compared to older single-pane or failed double-pane units, noticeably lowering heating costs in the Lower Mainland.
