Old windows cost you money every month. Drafts, heat loss, condensation between panes, frames that stick or won’t lock these aren’t minor annoyances. They’re signs that your windows have reached the end of their useful life and are actively working against your comfort and your energy bills. FONZ Construction replaces windows throughout the Portland metro area with energy-efficient products installed with the precision that actually delivers the performance on the box. We’re a local contractor not a national franchise with a sales team on commission and we give you honest recommendations, clear pricing, and work that’s done right.
Energy Savings According to the U.S. Department of Energy, inefficient windows can account for 25–30% of residential heating and cooling costs. Modern double- and triple-pane windows with low-E coatings and argon gas fills dramatically reduce heat transfer in both directions keeping warmth in during Oregon winters and heat out in summer
Comfort Cold radiating off single-pane glass in January, drafts at the frame, rooms that never feel warm enough these are quality-of-life issues that new windows fix immediately
Condensation & Moisture Condensation between panes means the seal has failed and the insulating gas has escaped. The window is now performing close to single-pane. Fog that won’t clear isn’t just ugly it’s a sign the window isn’t working
Noise Reduction Multi-pane windows with proper sealing reduce outside noise significantly. If traffic, neighbors, or the neighbor’s dog are audible inside your home, window quality is part of the equation.
Home Value Window replacement consistently ranks among the higher-ROI home improvement investments at resale. Updated, efficient windows are a visible upgrade buyers notice and value.
The most common residential window style both sashes tilt in for easy cleaning, universal fit for most openings, and a classic look that suits everything from historic Portland craftsmans to newer builds.
Hinged on one side, cranked open like a door. Casements provide the tightest seal of any operable window style when closed (the frame compresses against the sash), and excellent cross-ventilation when open. A great choice for Oregon's mix of rainy and temperate seasons.
Hinged at the top, opening outward from the bottom. Awning windows let you ventilate even in rain — which makes them arguably the most practical operable window style for the Pacific Northwest. Popular in kitchens, bathrooms, and as accent windows above fixed panes.
Clean, minimal, easy to operate. Sliding windows are a good solution for wide horizontal openings where a double-hung or casement wouldn't fit the architecture.
Maximum light, maximum view, maximum energy performance. Fixed windows don't open, so there's no operable seal to degrade over time. Ideal for living rooms, feature walls, and any opening where ventilation isn't the goal.
Architectural focal points that add interior space, natural light, and strong curb appeal. Bay windows (typically three panels, with angled side units) and bow windows (four or more panels in a curve) are transformative upgrades that increase how a room feels.
Box-style windows that extend outward, creating a small interior shelf bathed in light from three sides. Popular in kitchens for plants and herbs.
Choosing the right glass matters as much as choosing the right frame. We walk you through:
Double-pane with low-E coating and argon fill is the right choice for most Oregon homes it delivers strong thermal performance without the cost premium of triple-pane. Triple-pane makes more sense in extremely cold climates or for homeowners targeting peak energy performance.
Low-emissivity coatings are microscopically thin metallic layers applied to the glass. They reflect infrared heat back to its source keeping interior heat inside in winter and blocking solar heat gain in summer. Standard on virtually all quality replacement windows today.
The space between panes is filled with argon (or krypton in high performance units) instead of air. These gases conduct heat more poorly than air, improving the window's thermal resistance. Argon is cost-effective and standard; krypton is used in thinner profiles where you need maximum performance in less space.
Required by code in certain locations (within 18 inches of a door, in bathrooms, near stairs). We ensure your installation meets all applicable code requirements.
The most popular choice for replacement windows low maintenance, good thermal performance, resistant to moisture and rot, and available in a range of colors. Modern
vinyl frames are far better than early-generation vinyl products.
Premium performance. Fiberglass expands and contracts at nearly the same rate as glass, which means better long-term seal integrity. Stronger, stiffer, and dimensionally more stable than vinyl, with a slightly higher cost
Wood interior for that warm aesthetic, aluminum or fiberglass exterior cladding for weather resistance. The right choice for homeowners who want the look of wood inside without the maintenance exposure of exposed wood outside.
The best window on the market performs poorly with a bad install. This is not a small caveat it’s the difference between a window that delivers on its specs for 30 years and one that develops problems in 3.
Improper flashing allows water to work behind the frame at the sill and head the #1 cause of window-related water damage
Missing sill pan means any water that gets into the rough opening has nowhere to drain
Poor shimming leads to frames that rack, sashes that bind, and locks that don’t engage
fully
Incorrect sealing lets air infiltration defeat the thermal performance you paid for
Skipped vapor barriers create moisture issues in the wall assembly over time
Our installation crews are trained to do this right because a window that fails isn’t just an inconvenience, it’s a moisture intrusion event waiting to damage your wall framing and
insulation.

do great work. We were very happy with everything start to finish.
