The Eichler Standard

Window Wall and Glass Upgrades for Eichler Homes

Eichler houses are famous for their floor-to-ceiling window walls and open, light-filled spaces. In Hayward’s climate, updating these glass walls is key for comfort and efficiency. At GMJ Construction, we modernize Eichler windows with energy-efficient, dual- or triple-pane glazing that meets California codes while preserving the classic Eichler look. Our Eichler home restoration team carefully replaces old single-pane panels with insulated glass walls, reducing heat gain in summer and heat loss in winter. We also handle sliding patio doors and skylights — integrating advanced frames and weatherproofing that boost comfort without altering Eichler charm. Learn more about energy-efficient upgrades for Eichler homes to see how modern windows can improve your home’s comfort and value.

Siding Replacement and Exterior Cladding

The exterior siding on Eichler homes — often grooved redwood or plywood — gives them their mid-century character. Over time, wood siding can warp, rot, or fade. Our experts at GMJ provide professional Eichler siding installation to restore or refresh your home’s facade. We offer solutions from like-for-like wood siding to durable fiber-cement panels cut with the classic grooves. For owners looking for a different look, we install stucco finishes and modern cladding options that match Eichler lines.

Proper installation is crucial: our crews install weather barriers and flashing to prevent moisture intrusion and dry rot in Hayward’s weather. Check out our guide on installing siding on a house for insight into the process. With GMJ handling the full job — demoing old boards, repairing framing, adding insulation, then putting up new siding and trim — your Eichler’s exterior will be protected and stylish for decades.

Other Exterior Upgrades and Curb Appeal

Beyond windows and siding, we help Eichler homeowners with any exterior project to boost curb appeal and function. Need a new driveway or patio? Our team pours and finishes driveways in concrete or asphalt — we cover concrete vs. asphalt driveways and can recommend the best choice for your site. We handle exterior painting in mid-century-friendly palettes, durable fencing, decks, and pergolas that fit the Eichler aesthetic.

Our ADU construction team can even convert a carport or garage into a stylish living space while matching the original post-and-beam lines. Any addition — like enclosing an atrium or adding skylights — is done with respect for Eichler design principles. You can see the results in our projects gallery, where Bay Area Eichler exteriors have been transformed without losing their character. From new concrete patios to custom landscaping with drought-tolerant plants, our focus is making your Eichler’s outside look as good as the inside.
