Trusted by Local Families
Built for Homeowners Who Expect Clear Glass, Tight Seals, and Work Done Right
Energy Savings
Cleaner Look
Better Security
Drafty frames let cold air seep through. Condensation gathers between panes that should be clear. Seals crack and fail, and every time the wind picks up, you feel it inside the house.
Wait too long and the problem spreads. Energy bills climb. Frames warp. Water damage creeps into walls. The repairs you put off today turn into bigger, costlier fixes tomorrow.
PNW Prestige Exteriors helps Renton families and businesses upgrade comfort, energy efficiency, and curb appeal with window installations and repair that last. From single-pane drafts to failed seals, we handle every detail of your window project with clean workmanship and honest answers.
Each installation covers proper flashing, level alignment, and weatherstripping so your new windows perform through rain, temperature swings, and daily use. We also repair broken seals, replace cracked glass, and adjust hardware when a full replacement isn’t necessary yet. Our crew brings fiber cement siding, door replacement, and trim skills to the same site, so upgrades coordinate smoothly.
You get punctual arrivals, drop cloths that protect your floors, and debris removal before we leave. Every window is tested for smooth operation and a tight seal, and you’ll know how to maintain it long after we’re gone.
Energy-efficient installations and expert repairs that restore clarity, seal out drafts, and improve comfort year-round.
Secure, weather-tight entries that operate smoothly and make every arrival feel like you’re stepping into a well-built home.
Durable cladding that stands up to rain, protects against moisture intrusion, and keeps your exterior looking sharp for years.
Precise trim work that completes the look, resists rot, and frames your home with clean lines that hold up through changing seasons.
Clear glass, properly sealed panes, and smooth operation give you unobstructed views and bright rooms that feel bigger.
No drafts, no condensation between panes, and stable indoor temperatures even when Renton weather swings.
Quality frames and hardware stay square and hold up to rain, keeping you from repainting or adjusting latches every season.
The installers arrived on time, measured every opening twice, and replaced all six windows in less than a day. No mess left behind, and the difference in temperature control was noticeable that same evening. They even adjusted one frame that had settled slightly over the years.

We needed one door and two window replacements after a leak damaged the frames. The crew walked us through material choices without pushing the most expensive option, finished the work in two visits, and made sure everything sealed properly before they left.

Every frame is leveled and plumbed so sashes open smoothly without binding.
Caulk and backer rod seal the perimeter and prevent drafts through frame gaps.
Insulated glazing with argon fill reduces heat transfer and lowers your monthly energy use.
Quality locks and hinges stand up to daily operation without loosening.
Interior trim is caulked and touched up so each install looks finished inside and out.
Homeowners across the greater Seattle region count on our window installation and repair expertise. We know how Pacific Northwest weather affects frames, seals, and glass, and every installation is designed to handle rain, wind, and temperature swings year after year.
Most single-window replacements take two to four hours. Multi-window projects usually finish in one to two days, depending on the number of openings and frame conditions.
Yes, if the frame and sash are solid. We replace the insulated glass unit while keeping your existing frame, which saves time and cost compared to full replacement.
Absolutely. We install vinyl, fiberglass, wood, and composite frames. Each material has different durability and maintenance needs, and we walk you through the trade-offs during the estimate.
Condensation between panes, difficulty opening or closing, drafts around the frame, and visible rot on sills usually mean replacement. Cracked glass or broken hardware can often be repaired.
Yes. The glass itself carries a manufacturer seal warranty, typically ten to twenty years. Our installation work is covered separately under a workmanship guarantee that protects against leaks and fit issues.
