The Brands We Install

Milgard & Ply Gem Windows

We primarily install two trusted window brands — Milgard for homeowners who want premium Pacific Northwest-engineered quality, and Ply Gem for those who need reliable, energy-efficient windows at a more accessible price point. Both brands are ENERGY STAR® certified and meet Oregon's energy code requirements.

Premium Brand★ Our Top Recommendation

Milgard Windows & Doors

Designed for the Pacific Northwest

Milgard is our premier window brand — a Pacific Northwest company founded in Tacoma, Washington in 1962 that has spent over 60 years engineering windows specifically for the wet, variable climate of the region. Milgard windows are known for exceptional quality, beautiful design, and one of the best warranties in the industry.

Why we recommend it: Milgard is built for Oregon. Their windows are engineered for the Pacific Northwest's specific climate challenges — high rainfall, temperature swings, and coastal salt air. When you choose Milgard, you're getting a product designed for exactly where you live.

Ply Gem Windows

Reliable Performance, Accessible Price

Why It Matters

What New Windows
Do for Your Home

Reduce Energy Bills

Single-pane or failed double-pane windows are one of the biggest sources of heat loss in Oregon homes. Modern double or triple-pane Low-E windows can reduce heating costs by 15–25%.

Reduce Outside Noise

Triple-pane glass and laminated glass options dramatically reduce traffic noise, neighborhood sounds, and wind — making your home noticeably quieter.

Stop Drafts & Moisture

Failed window seals, rotting frames, and poor weatherstripping allow cold air and moisture into your home. New windows with proper installation eliminate drafts and condensation problems.

Protect Interiors from UV

Low-E glass coatings block up to 84% of UV rays — protecting hardwood floors, furniture, and artwork from fading without noticeably reducing visible light.

Time to Replace?

Signs Your Windows
Need Replacing

Drafts or cold spots near windows even when closed
Condensation or frost between the glass panes (failed seal)
Difficulty opening, closing, or locking windows
Visible rot, warping, or deterioration in frames or sills
Noticeably higher heating or cooling bills
Outside noise is louder than it used to be
Single-pane glass — no longer meets Oregon energy code
Windows more than 20–25 years old

Oregon Energy Code

ENERGY STAR® Pacific Northwest Requirements

Oregon falls in the ENERGY STAR® Northern Climate Zone. Replacement windows must meet minimum performance thresholds to comply with Oregon's energy code and qualify for utility rebates.

U-Factor≤ 0.27

Measures heat loss through the window. Lower is better.

Solar Heat Gain Coefficient (SHGC)≤ 0.40

Measures solar heat admitted. Lower reduces summer cooling loads.

Visible Transmittance (VT)≥ 0.30

How much visible light passes through. Higher means brighter interiors.

All windows we install meet or exceed Oregon ENERGY STAR® requirements. We handle all permit and code compliance.

Window Styles

Window Types We Install

We install all major window styles — from the everyday double-hung to architectural bay & bow windows. Every installation includes proper flashing, insulation, and weatherproofing.

Double-Hung Windows

Most Popular

The classic American window — both the upper and lower sashes slide vertically, making them easy to clean from inside the home. Double-hung windows are the most versatile choice for Oregon homes, fitting virtually any architectural style from craftsman bungalows to modern farmhouses.

  • Both sashes tilt in for easy interior cleaning
  • Excellent ventilation control — open top, bottom, or both
  • Fits virtually any home style
  • Available in single or double-pane glass
  • Wide range of frame colors and finishes
  • Most cost-effective replacement window option

Best for: Bedrooms, living rooms, traditional homes

Casement Windows

Best Seal

Casement windows are hinged on one side and swing outward with a crank handle — like a door. When closed, the sash presses tightly against the frame, creating one of the best weathertight seals available. This makes them an excellent choice for Oregon's rainy climate where air and water infiltration are constant concerns.

  • Hinged on side — cranks open outward
  • Superior weathertight seal when closed
  • Excellent ventilation — full opening captures cross-breezes
  • No rail in the middle — unobstructed views
  • Ideal for hard-to-reach locations over counters or sinks
  • Available in single or double-pane configurations

Best for: Kitchens, bathrooms, contemporary homes

Sliding Windows

Low Profile

Sliding windows (also called gliding windows) open horizontally — one panel slides along a track while the other remains fixed. They're a clean, modern choice that works especially well in contemporary homes and in locations where an outward-swinging window isn't practical (near walkways, patios, or decks).

  • Horizontal sliding operation — no outward swing
  • Clean, contemporary appearance
  • Easy to operate — no cranks or latches
  • Great for wide openings and panoramic views
  • Ideal where outward clearance is limited
  • Low maintenance — fewer moving parts

Best for: Contemporary homes, wide openings, patios

Picture Windows

Maximum Light

Picture windows are fixed — they don't open — but they deliver maximum glass area, unobstructed views, and the best thermal performance of any window type. Because there are no moving parts or operable hardware, picture windows are extremely energy-efficient and virtually maintenance-free. Often combined with operable windows on either side.

  • Fixed — maximum glass area and views
  • Best thermal performance (no operable gaps)
  • Virtually maintenance-free
  • Ideal for capturing specific views or maximizing light
  • Often combined with casement or double-hung flankers
  • Available in custom shapes and sizes

Best for: Living rooms, great rooms, view-facing walls

Bay & Bow Windows

Architectural Impact

Bay windows project outward from the exterior wall, typically with a large center picture window flanked by two angled side windows. Bow windows use four or more windows in a gentle curve. Both styles add architectural character, create interior shelf or seating space, and dramatically increase natural light. A premium upgrade that adds real curb appeal and resale value.

  • Projects outward — creates interior shelf or seat
  • Bay: center picture + two angled side windows
  • Bow: four or more windows in a gentle curve
  • Dramatically increases natural light
  • Significant curb appeal and resale value
  • Custom sizing and configuration available

Best for: Living rooms, dining rooms, master bedrooms

Awning Windows

Rain-Ready

Awning windows are hinged at the top and swing outward from the bottom — like an awning. This unique design lets you keep the window open for ventilation even during light rain, since the glass itself acts as a weather shield. Popular in Oregon for exactly this reason. Often installed above or below other windows for added ventilation without sacrificing privacy.

  • Hinged at top — opens outward from bottom
  • Can stay open during light rain
  • Excellent ventilation without sacrificing privacy
  • Great for basements and high wall placements
  • Often paired with picture windows for combo units
  • Strong weathertight seal when closed

Best for: Bathrooms, basements, rainy climates like Oregon

Glass Options

Glass Packages &
Performance Specs

The glass unit is the heart of any window's energy performance. We offer double-pane, triple-pane, and specialty glass options — all meeting or exceeding Oregon's ENERGY STAR® requirements.

Standard

Double-Pane Low-E

  • Double-pane insulated glass unit (IGU)
  • Low-E coating — reflects infrared heat
  • Argon gas fill between panes
  • U-Factor: ~0.30 | SHGC: ~0.25
  • Meets ENERGY STAR® Pacific NW requirements
  • Condensation-resistant warm-edge spacer

The baseline for any quality window replacement in Oregon. Dramatically outperforms single-pane glass in energy efficiency and comfort.

★ Our Recommendation

Enhanced

Triple-Pane Low-E

  • Triple-pane insulated glass unit (IGU)
  • Dual Low-E coatings for maximum performance
  • Krypton or argon gas fill
  • U-Factor: ~0.20 | SHGC: ~0.22
  • Superior noise reduction vs. double-pane
  • Ideal for Oregon coast and high-rainfall areas

Our most recommended upgrade for Oregon homeowners — the additional cost pays back in energy savings and comfort, especially in colder inland areas.

Specialty

Impact, Tempered & Obscure

  • Tempered safety glass (required by code in many locations)
  • Obscure/frosted glass for privacy
  • Laminated glass for sound attenuation
  • Impact-resistant glass for coastal areas
  • Decorative glass — grilles, patterns, art glass
  • Custom tints and coatings available

Required by Oregon building code in certain locations (within 18" of a door, in bathrooms, stairways). We handle all code compliance.

Frame Options

Window Frame Materials:
Vinyl, Fiberglass & Wood

Vinyl (uPVC)

Best Value

Advantages

  • Lowest maintenance — never needs painting
  • Excellent thermal performance
  • Moisture and rot resistant
  • Most cost-effective option
  • Available in many colors and finishes
  • Lifetime warranty from most manufacturers

Considerations

  • Can expand/contract in extreme temps
  • Limited color options vs. wood
  • Cannot be repainted

The most popular window frame material in Oregon for good reason — vinyl delivers excellent performance, zero maintenance, and strong value. Our default recommendation for most replacement projects.

Fiberglass

Premium Performance

Advantages

  • Strongest frame material available
  • Minimal thermal expansion/contraction
  • Can be painted — color flexibility
  • Excellent energy performance
  • Slim sightlines — more glass, less frame
  • Extremely long lifespan

Considerations

  • Higher cost than vinyl
  • Fewer manufacturers offer it
  • Heavier than vinyl

The premium choice for homeowners who want the best long-term performance. Fiberglass frames are dimensionally stable, paintable, and built to last 50+ years.

Wood

Classic Beauty

Advantages

  • Natural warmth and beauty
  • Excellent insulation properties
  • Can be painted or stained any color
  • Traditional aesthetic for historic homes
  • Structural strength

Considerations

  • Requires regular painting/staining
  • Susceptible to moisture and rot if not maintained
  • Higher cost than vinyl
  • Not ideal for Oregon's wet climate without proper maintenance

Wood windows are beautiful but demand commitment in Oregon's wet climate. We recommend wood-clad options (aluminum or fiberglass exterior, wood interior) for the best of both worlds.

Aluminum

Commercial Grade

Advantages

  • Extremely strong and durable
  • Slim, modern sightlines
  • Ideal for large commercial openings
  • Corrosion resistant
  • Low maintenance

Considerations

  • Poor thermal performance (conducts heat/cold)
  • Requires thermal break for residential use
  • Can condensate in cold climates

Best suited for commercial applications or modern architectural projects where slim sightlines and structural strength are priorities. Thermal-break aluminum is required for energy code compliance.

Our Process

How We Install Your Windows

01

Free Estimate

We measure every opening, assess the existing frames and surrounding trim, and walk you through window style, glass package, and frame material options — with transparent pricing.

02

Remove Old Windows

We carefully remove existing windows and inspect the rough opening, sill, and surrounding framing for rot, moisture damage, or structural issues that need to be addressed before new windows go in.

03

Flash & Seal

Proper flashing and air sealing around the rough opening is critical — it's what keeps water out of your walls. We never skip this step. All installations include code-compliant flashing and foam insulation.

04

Install & Finish

New windows are set, shimmed, and secured to manufacturer specifications. Interior and exterior trim is reinstalled or replaced, caulked, and finished. We clean up completely before final walkthrough.

Common Questions

Window Replacement FAQ

What is the best window type for Oregon homes?

For Oregon's rainy climate, casement and awning windows offer the best weathertight seal. Double-hung windows are the most versatile and popular choice. All should be paired with double or triple-pane Low-E glass with argon gas fill to meet Oregon's energy code requirements.

Should I choose double-pane or triple-pane windows in Oregon?

Double-pane Low-E windows meet Oregon's ENERGY STAR requirements and are a significant upgrade over single-pane. Triple-pane windows offer better thermal performance and noise reduction — recommended for colder inland areas, coastal locations, or homes near busy roads.

What window frame material is best — vinyl, fiberglass, or wood?

Vinyl is the most popular choice for Oregon replacement windows — it offers excellent performance, zero maintenance, and strong value. Fiberglass is the premium option with better dimensional stability and paintability. Wood is beautiful but requires more maintenance in Oregon's wet climate.

How long does window replacement take?

Most window replacement projects are completed in one to two days. A full-home replacement of 10–15 windows typically takes one to two days with our crew. Individual window replacements can often be completed in a single morning.
