Window Installation & Replacement in the Bay Area
Builder-grade windows reach the end of their service life around the twenty year mark: seals fail, glass fogs, and a west-facing wall turns the afternoon into an expense. We replace them with Anlin windows built in California, sized to your exact opening, installed with proper flashing and full weather sealing. Most whole-home replacements take one to three days on site.

What to Expect: Our 5-Step Installation Process
We've refined our process over 25 years and hundreds of Bay Area installations to deliver a smooth, transparent, and friendly experience. From your first call through the final walkthrough, you'll know exactly what's happening, when it's happening, and who to contact with questions. Here's how your project will unfold.
Free In-Home Consultation
We meet at your property to assess your current windows, understand your aesthetic and performance goals, take precise measurements, and recommend the ideal Anlin products for your home's architecture and your budget. We also review HOA requirements and architectural guidelines where applicable.
Detailed Proposal & Contract
Within 48 hours, you receive a transparent, itemized proposal with product specifications, glass packages, frame colors, hardware finishes, grid patterns, pricing, and a clear project timeline. No hidden fees, no pressure — just a detailed plan you can review and approve at your pace.
Custom Manufacturing & Scheduling
Once approved, we place your custom order with Anlin's California factory. Every window is built to your exact specifications. We coordinate delivery and schedule your installation date so everything arrives on time and in pristine condition.
Professional Installation
Our licensed, uniformed crew arrives on schedule, protects your floors and furnishings, removes old units, and installs your new windows with precise fitting, proper flashing, and full weather sealing. We work room by room to minimize disruption to your daily routine.
Final Inspection & Walkthrough
We test every window for smooth operation, inspect all seals and finishes, clean the work area thoroughly, remove all debris, and walk you through the completed project. Your satisfaction is our standard — we don't leave until everything is perfect.
Cost Expectations
We believe in transparent pricing with no surprises. The cost of your project depends on several factors — here's what to expect when budgeting for a window replacement in your Bay Area home:
- Per-window pricing typically ranges from $400 for a standard slider to $5,000+ for a custom bay or bow window, depending on series, size, and glass package
- Whole-home replacement of 15–25 windows in Bay Area homes generally ranges from $15,000 to $50,000+ depending on product selection and customization
- Premium glass upgrades — SR50 Sound Reduction, First Guard Security, or 4X Tempered Safety — add to the per-unit cost but deliver significant comfort and security value
- Custom frame profiles, sculptured grids, and specialty geometric shapes increase per-unit pricing but are often essential for architectural consistency
- Second-story installations, stucco exteriors, and homes requiring architectural review or HOA coordination may involve additional labor and project management time

Questions Homeowners Ask Before Working With Us
Here are the questions we hear most often from homeowners in Lafayette, Danville, Los Gatos, and across the Bay Area before they decide to work with Tadek Construction.
For homes in San Ramon, Danville, Pleasanton, and the Tri-Valley, whole-home window replacement typically ranges from $15,000 to $50,000+ depending on the number of windows, the Anlin series selected (Catalina, Panoramic, or Coronado), glass packages, and customization. Per-window pricing ranges from $400 for a standard slider to $5,000+ for custom bay or bow windows. We provide a detailed, itemized proposal after your free consultation so you know exactly what you're investing in.
The installation itself typically takes one to three days on site. However, because every Anlin window is custom-manufactured to your exact specifications in their California facility, the manufacturing lead time runs four to eight weeks. We provide a clear timeline during your consultation and keep you updated throughout. Most of our clients are pleasantly surprised at how smooth and fast the installation phase is — we work efficiently room by room to minimize disruption.
It depends on your home's orientation and your comfort priorities. Infinit-E standard glass comes on every window and provides excellent solar protection for the Bay Area's temperate climate. SunMatrix Low-E is a 4-layer coating that blocks 99% of UV rays — we recommend it for south- and west-facing exposures to protect furnishings and artwork. The Anlin Sound Package reduces outside noise by up to 50%, ideal for homes near busy corridors or flight paths. We'll walk you through the options during your consultation and bring physical samples so you can decide with confidence.
Yes. Many of the communities we serve — including Blackhawk, Diablo, and Rossmoor — have HOA or architectural review requirements. We're experienced in preparing the documentation these committees need, including product specifications, color samples, and installation plans. Your project coordinator handles this process for you as part of our service.
We specialize in full window replacement rather than repairs. When builder-grade windows reach the twenty-year mark, seals have typically failed and the glass is fogging — at that point, repair is a short-term fix that doesn't address the underlying failure. Replacing with new windows gives you a lifetime warranty, proper flashing, and full weather sealing. Anlin is our primary partner, and we also install Milgard, Andersen and Pella — we quote whichever line fits the house and the budget. If you're unsure whether your windows need repair or replacement, we'll give you an honest assessment during your free consultation.
