Pella & Andersen Window Replacement in Longmont, Colorado

Pella and Andersen are the two window brands Longmont homeowners ask for most. Both make excellent windows, but the brand matters less than choosing the right series for your house and installing it correctly. We install both, and we’ll show you where each line makes sense for your budget, your home’s style and Colorado’s sun and temperature swings.

Pella Window Lines We Install

• Pella 250 Series — vinyl windows with strong energy performance at a moderate price. A popular choice for whole-house replacements.
• Pella Impervia — fiberglass windows that resist warping and fading in high-altitude UV and wide temperature swings.
• Pella Lifestyle Series — wood interior with aluminum-clad exterior, with optional between-the-glass blinds and shades.
• Pella Reserve — premium wood windows for historic and custom homes.

Andersen Window Lines We Install

• Andersen 100 Series — made from Fibrex composite, stronger and more stable than vinyl, at an approachable price.
• Andersen 400 Series — wood interior with a low-maintenance exterior cladding. Andersen’s best-known line.
• Andersen E-Series and A-Series — architectural and custom lines with wide color, shape and hardware options.

Note: Renewal by Andersen is sold only through Renewal’s own retail locations. We install Andersen’s dealer-channel lines above, which often cost less for comparable performance.

Pella vs. Andersen: Which Is Better?

Neither brand is universally better. For value-focused replacements, Pella 250 and Andersen 100 are the usual comparison. For a wood-interior look, Pella Lifestyle and Andersen 400 compete closely. For the toughest exterior in direct western sun, fiberglass Pella Impervia and Fibrex Andersen 100 both hold up well. We’ll quote the lines that fit your project side by side.

Installation Is What Makes Windows Perform

A premium window installed poorly will leak air and water. We choose between insert and full-frame replacement based on the condition of your existing frames, then flash, insulate and trim every opening to manufacturer instructions. Because we also do siding and stucco repair, we can fix damaged trim and exterior around the window in the same visit.

Window Replacement Pricing in Longmont

Our installed price is $1,600 per window, and the per-window price drops as you add windows. Premium lines, oversized units, specialty shapes and patio doors are quoted individually. Estimates are free and itemized by window.
