Service Area FAQ's

Do you serve homeowners outside the Tri-Valley?

Yes. Custom Exteriors has been based in Pleasanton since 1997, but our AAMA Certified Master Installers complete projects throughout the Bay Area — from Central and East Contra Costa County to Oakland, San Francisco, and the South Bay. If your city isn't listed above, contact us to confirm we serve your area.

Do I need to visit the Pleasanton showroom to get an estimate?

No. The showroom lets you see and handle full-size window, siding, and door displays in person, but it isn't required. We offer free, no-pressure in-home consultations across our full service area, so homeowners in San Jose or San Francisco get the same on-site estimate as those in Pleasanton.

Is pricing or installation quality different depending on location?

No. Every project is completed by the same AAMA Certified Master Installers using the same Infinity from Marvin windows, James Hardie fiber cement siding, and ProVia or Therma-Tru entry doors, regardless of city. Pricing is based on project scope, not location.

How is "Extended Service Area" different from the other regions listed?

Extended Service Area covers locations like Benicia and Tracy that fall outside our core Bay Area regions but are still within reach of our installation teams. These projects are scheduled the same way as any other, free in-home consultation, same AAMA Certified Master Installers, same product lineup, just confirm availability when you contact us, since scheduling in these areas can have longer lead times.
