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.
Hillsboro's Tualatin Valley humidity and 2000s housing stock create a specific window replacement case. These are the three reasons ProVia is the right answer here.
Hillsboro's position in the western Tualatin Valley creates persistent morning fog and elevated ambient humidity through most of the year. These conditions stress window seals from the exterior while interior temperature differentials stress from inside — the combination accelerates seal failure in standard vinyl IGUs.
Hillsboro's temperature swing from cold, wet winters to warm, dry summers makes vinyl frame construction quality a real performance consideration. ProVia Aspect multi-chamber vinyl construction is engineered for Pacific Northwest temperature cycling — Energy Star certified and a substantial upgrade from the aging builder-grade frames common in Hillsboro's 2000s developments.
Oregon requires CCB-licensed contractors for window replacement. Left Coast Exteriors holds CCB License 217914. We coordinate City of Hillsboro 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 Hillsboro permit when changing window size, type, or framing. Like-for-like replacement in the same opening may qualify for an exemption. Oregon CCB-licensed contractors handle permit determination — we make that call and pull required permits as part of every project. CCB License 217914.
ProVia Aspect all-vinyl replacement windows run $800–$1,400 installed per window for standard residential sizes. 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, size, and framing repairs needed. Written itemized estimates provided after free measurement.
Both are high-quality ProVia replacement windows. Aspect is all-vinyl with multi-chamber frame construction — Energy Star certified and the right specification for most Hillsboro homes. 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. Aeris is the premium interior finish upgrade for homeowners who want authentic wood aesthetics inside without exterior wood maintenance.
A full-home replacement of 10–15 windows typically completes in 1–2 days once product is on-site. ProVia windows are custom-manufactured to your opening sizes — lead time is typically 4–6 weeks from order to installation. We measure, order, and schedule installation in one project scope.
Window replacement often connects to adjacent exterior work.
