Every window installer will tell you they do quality work. Here's what actually differentiates the companies that back that claim from the ones that don't.

‍

For homeowners throughout the East Bay and San Francisco Bay Area, our commitment doesn’t end when the job is finished. Since 1997, Custom Exteriors has remained dedicated to standing behind our work and the products we install, providing ongoing support that reinforces our focus on long-term performance, accountability, and homeowner satisfaction. Our decades of experience and hundreds of five-star reviews reflect the trust local homeowners place in our team and the consistent quality we deliver on every project.

• Superior Products – We offer windows that are made by industry-leading manufacturers, like Infinity from Marvin, and designed to provide exceptional beauty, strength, security, durability, and energy efficiency, so you’ll receive the utmost value for your investment.  
• AAMA Certified Master Installers – We treat your home like our own. We have a team of our own, never subcontracted AAMA Certified Master Installers who will provide a flawless, airtight installation for comfort and soundproofing benefits.  Our team meets the installation standards that manufacturers require to honor the product warranty, so your warranty doesn't have a hidden loophole.
• Unmatched Warranties – We will stand behind your new windows with an unbeatable labor warranty, in addition to the manufacturer’s warranty, so you can have total peace of mind.
• Full-Time Employees, Not Subcontractors - Our installers are Custom Exteriors employees. They've been on our team for years, trained to our standards, and accountable to us — not to the lowest bidder on a job board. When reviewers name Roman, Benny, Tadeo, Marcial, and Robert by name, that's what a consistent, employee-based team looks like.
• EPA Lead-Safe RRP Certified - Required for renovation work on homes built before 1978, and common in established neighborhoods across Pleasanton, Walnut Creek, Livermore, and Oakland. Before installation begins, our team confirms whether lead-safe procedures apply and follows them.
• Local Showroom in Pleasanton - Our Pleasanton showroom exists for one reason: so you're not making a major decision based on photos and PDFs. Most exterior contractors don't have one. Ours has full-size window and door displays, fiberglass and vinyl side by side. so the difference is obvious before you sign anything.
