We install ProVia Aspect all-vinyl and ProVia Aeris wood-clad vinyl replacement windows. Both are custom-manufactured to your opening sizes. Full product guide →
ProVia Aspect is a premium all-vinyl replacement window with multi-chamber frame construction for superior thermal performance and structural rigidity. Energy Star certified, available in a full range of profiles and grid configurations. Custom-manufactured to your exact opening measurements — no filler strips or adapter frames. The right specification for most residential replacement projects.
ProVia Aeris is a wood-clad vinyl window — vinyl exterior with a real-wood interior that can be painted or stained to match interior trim and millwork. For homeowners who want authentic wood interior aesthetics alongside vinyl exterior durability, Aeris is the premium interior finish upgrade in the ProVia lineup.
Tigard's valley fog conditions and aging housing stock create a specific window replacement case. These are the three reasons ProVia is the right answer here.
Tigard's Tualatin Valley bowl fog creates sustained moisture at exterior window surfaces through the wet season. ProVia's superior IGU construction uses high-durability spacer systems designed to resist the sustained exterior moisture exposure that causes premature seal failure in standard builder-grade windows.
Tigard's swing from cold, wet winters to warm, dry summers places real demands on window frame construction quality. ProVia Aspect all-vinyl with multi-chamber construction is engineered for Pacific Northwest temperature cycling — Energy Star certified and a substantial upgrade from the aging builder-grade frames common in Tigard's 1960s–1990s housing stock.
Oregon requires CCB-licensed contractors for window replacement. Left Coast Exteriors holds CCB License 217914. We coordinate City of Tigard Building Department permits and final inspection on every project.
Authorized Dealer status means we're trained to ProVia's installation standards and can offer the full manufacturer warranty — including the installation component. Builder-grade installers cannot offer this backing.
ProVia windows are custom-manufactured to your exact opening sizes. We measure each opening precisely, order to specification, and install without filler strips or adapter frames that compromise thermal performance and appearance.
We address the full window opening: exterior flashing, interior air sealing, and trim restoration. A ProVia window installed without proper air sealing and flashing doesn't deliver the thermal and moisture performance the product was designed for.
We assess every window in the home — seal failure, hardware condition, frame integrity, and energy performance. Written assessment with photos provided.
Each opening is measured to the nearest 1/8 inch. ProVia windows are custom-manufactured to these measurements — no standard sizes, no adapter frames.
Custom windows typically have a 4–6 week manufacturing lead time. We manage the order and scheduling — you get one call when everything is ready.
Most full-home replacements (10–15 windows) complete in 1–2 days. Each opening gets proper flashing, air sealing, and interior trim restoration.
We demonstrate operation of every window installed. Written warranty documentation covers both the ProVia product warranty and our installation workmanship.
Window replacement in Oregon may require a City of Tigard permit depending on scope. Like-for-like replacement may qualify for exemption; size changes require a permit. Oregon CCB-licensed contractors make the determination — we handle applications where required. CCB License 217914.
ProVia Aspect all-vinyl replacement windows run $800–$1,400 installed per window. ProVia Aeris wood-clad vinyl runs $900–$1,500 per window. A full-home replacement of 10–15 windows typically runs $12,000–$25,000 depending on product and scope. Written itemized estimates provided after free measurement.
Key replacement indicators: fogged glass between panes, visible drafts or cold air infiltration, windows that won’t open or lock, interior condensation running down glass, or visible frame damage. We assess the full window condition and provide repair vs. replace guidance at the free consultation.
ProVia windows are custom-manufactured to your opening sizes — lead time is typically 4–6 weeks from order to installation. Installation of a full home (10–15 windows) typically completes in 1–2 days. We measure, order, permit, and schedule in one project scope.
