Enjoy Natural Lighting with VELUX Sun Tunnel Skylights

Serving San Francisco and East Bay Since 1983

Natural light provides a unique ambiance that could be just what you need for your property. VELUX Sun Tunnel skylights are an innovative solution to provide natural sunlight for essentially any building, bringing powerful, warm lighting to every corner.

Mares & Dow Construction & Skylights installs VELUX Sun Tunnel skylights for both residential and commercial properties.

Beautiful Indoor Spaces with Natural Light

VELUX Sun Tunnel skylights capture daylight at the roof and channel it down through a highly reflective tunnel to disperse it throughout interior spaces. This unique design provides pure, natural sunlight without any color shift to make interior spaces warm and welcoming.


This innovative technology allows for natural lighting in spaces where traditional skylights may not be feasible. With VELUX Sun Tunnels, hallways, bathrooms, laundry rooms, and more can enjoy the same beautiful ambiance as primary living spaces.
