Window and Door Installation Services That Fit Right, Work Smoothly, and Hold Up Over Time

Doors and windows aren’t just part of the exterior—they’re part of how your space functions every day. They affect your comfort, energy use, noise levels, and even long-term maintenance costs. At Sirius Construction, we provide window and door installation services designed for real performance—tight fits, clean finishes, and no loose frames or leaks.
 We don’t cut corners or rush through openings. Every unit is measured, installed, and finished like it’s protecting our own space—because quality matters where it counts.

Built for Tough Weather, Built for Real Use

 Extreme temperatures, shifting seasons, and heavy storms—these are things your windows and doors face every year. And if they’re not properly installed, you’ll feel it fast.
 That’s why we start with your property’s orientation, exposure, and wall type before we even bring in materials. Our weatherproof door installation process is focused on creating long-term protection against leaks and drafts. It includes:

• Precise flashing and sealing of all rough openings
• Correct threshold, drip edge, and insulation choices
• Flexible foam and shims to handle seasonal movement

From frame alignment to caulking joints, we ensure nothing is left loose or vulnerable.

Sliding Glass Doors That Slide Like They Should

 Sliding doors are a customer favorite—but not when they stick, rattle, or let in a draft. That’s why our sliding glass door installers take the time to prep, level, and install every unit like it’s the only one that matters.
 You can choose from:

• Double or triple-pane options for better insulation
• Custom sizes for non-standard or unique spaces
• Retrofit or new-construction installations

We’ll keep your space clean during install and ensure your door glides, locks, and seals perfectly before we leave.

Openings That Add More Than Just Light

 A window or door should be an upgrade, not a future repair bill. Our window and door installation services are designed to protect your structure while enhancing energy performance. That means stronger framing, proper sealing, and units that actually last through freeze-thaw cycles, direct sun, and everyday use.
 Our team installs:

• Casement, fixed, bay, and sliding windows
• Entry, patio, and side doors
• Custom-fit and energy-efficient models

We also install foam insulation around all units and test every latch, lock, and hinge before sign-off.
