Why Full-Frame Pella Installation Matters
Weatherguard exclusively performs full-frame window replacement when installing Pella windows. This method removes the entire existing window and frame, allowing our team to inspect the rough opening for moisture damage, apply proper spray foam insulation, install new flashing tape, and ensure a completely airtight seal.
Full-frame installation is especially critical in Colorado where extreme cold can cause condensation and moisture problems around improperly sealed windows. Insert (pocket) replacement leaves the old frame in place and may hide underlying moisture damage, reduce glass area by 1-2 inches per window, and compromise the thermal seal. Our full-frame approach maximizes the energy performance and longevity of your Pella investment.
Pella Warranty Coverage
Pella offers a limited lifetime warranty on most window products, covering glass, frame, and hardware. When installed by a certified installer like Weatherguard Construction, your Pella windows are backed by both the manufacturer's product warranty and our own workmanship guarantee.
Pella's warranty covers defects in materials and manufacturing including glass seal failure (fogging between panes), frame warping or bowing, hardware malfunction, and finish failure. Our installation warranty ensures proper fit, sealing, and flashing for the life of the windows.
Pella Energy Efficiency and Performance Ratings
Energy efficiency is a top priority for Colorado homeowners, and Pella windows consistently earn some of the highest performance ratings in the industry. All Pella window lines are ENERGY STAR certified for the Northern climate zone, and many exceed the minimum requirements by a significant margin.
Pella offers advanced glass packages including their InsulShield Low-E glass with argon gas fill and optional triple-pane configurations. Triple-pane glass with dual Low-E coatings and argon or krypton gas provides U-factors as low as 0.17, dramatically reducing heat loss during Colorado's coldest months. This level of insulation can reduce heating costs by 25-40% compared to older single-pane or failing double-pane windows.
For homeowners pursuing green building certifications or maximum energy savings, Pella's Advanced Low-E insulating glass paired with the Impervia fiberglass frame creates one of the most thermally efficient window assemblies available in the residential market. Weatherguard's installation team ensures proper air sealing and insulation around every window to maximize the energy performance of your Pella investment.
The Weatherguard Pella Installation Process
Every Pella window installation by Weatherguard follows a methodical process designed to ensure perfect results. Our process begins with a comprehensive in-home consultation where we measure every opening, discuss your style preferences and performance priorities, and help you select the ideal Pella series and options for your home.
On installation day, our factory-trained crew arrives with all materials and completes a thorough pre-installation walkthrough. We carefully remove existing windows, inspect and repair the rough opening framing, apply waterproof membrane and flashing tape per Pella's specifications, and install each new window with precision leveling, shimming, and fastening. We finish by applying low-expansion spray foam insulation around every frame, installing interior trim, and conducting a thorough quality inspection including operation and locking checks on every window.
Most whole-home Pella window replacement projects are completed in 2-4 days depending on the number of windows. We protect your home's interior with drop cloths and plastic sheeting, and leave every room cleaner than we found it.
