Siding & Window Replacement in Lake Oswego, OR
Lake Oswego properties have higher expectations for materials, for craftsmanship, for the finished result. FONZ Construction delivers the level of detail and quality that Lake Oswego homes require, with the honest communication and project management that makes the process smooth from start to finish. Whether you’re refreshing a lakeside home’s exterior, replacing windows throughout a hillside property, or doing a complete exterior transformation, we bring the execution to match your vision.
Lake Oswego’s mature tree canopy is one of its defining characteristics — and a real challenge
for home exteriors. Shade, debris accumulation, and constant moisture create ideal conditions for
moss, mildew, and the kind of long-term moisture pressure that degrades wood siding over time.
We install siding systems designed to perform in exactly these conditions:
James Hardie Fiber Cement
The right choice for most Lake Oswego homes. Moisture resistant, dimensionally stable, and available in profiles and finishes that suit the architectural character of Lake Oswego's neighborhoods.
For premium applications, we use the ColorPlus factory finish line, which provides a consistent, durable color that holds up beautifully in shaded, high-moisture environments.
Cedar Siding
For homeowners who want the natural warmth of wood on a high-end property, we source quality cedar and install it with the precision required to maximize its lifespan.
We're straightforward about maintenance requirements so your investment stays protected.
Windows in Lake Oswego
Lake Oswego homes often feature larger windows and more architectural glass than typical residential construction. We work with these larger openings comfortably proper framing, correct flashing for larger window units, and the attention to detail that prevents the kind of water infiltration that larger window openings are more susceptible to when not flashed correctly. We install premium vinyl, fiberglass, and wood-clad window options appropriate for higher-end properties.
