How To Replace Window & Door | West Coast Windows and Doors

Our Six-Step Process

Every project follows the same proven path — the same journey you can track in real time through our customer portal.

Consultation & Estimate

Estimate

Visit our Concord showroom by appointment or schedule an in-home consultation. We assess your needs, discuss product options from Andersen and Anlin, and provide upfront, straightforward pricing — no gimmicks.

Contract & Order

Contracted

Once you're ready to move forward, we finalize the contract and place your order factory direct. A down payment secures your project, and our team begins preparing detailed specifications for manufacturing.

Production & Blueprint

Production

Your windows and doors are manufactured to exact specifications by our partner factories. Blueprints are finalized and every detail — from glass type to hardware finish — is confirmed before scheduling.

Scheduling

Scheduled

When your products are ready, we coordinate an installation date that works for you. You'll receive clear communication about timing and what to expect on installation day.

Professional Installation

Installing

Our own long-term employees handle the installation — never subcontractors. Our factory-trained installers are bonded, certified, and committed to leaving your home clean and respected.

Completion & Satisfaction

Completed

After installation, we conduct a walk-through inspection with you. No job is considered complete until you are absolutely satisfied. We follow up with a customer satisfaction survey to ensure every detail meets our standard.

Know Who's Coming to Your Home

If you're having windows replaced, make sure you know who's coming to your house to do the work. Many window contractors don't use their own employees as installers, instead subcontracting the work. Even if the contractor is insured, it doesn't mean the subcontractors are.

“Make sure the contractor you're doing business with is fully and properly licensed and experienced, and has the proper insurance,” says Richard Beil. In particular, check that their workers' compensation insurance is enforced and their contractor's license is valid and not suspended.

Another priority is longevity. We recommend you show preference for companies that've been in business for some time, with long-serving employees and a good track record for reliability. “It's pretty evident that a company that's been in business for a long time is more likely to remain in business, because they're established both financially and in their marketplace.”

Questions to Ask Before You Buy

Before hiring any window contractor, consider asking these questions. We welcome every one of them.

Do you have any unresolved complaints at your local Better Business Bureau or the California State License Board?
Are you properly licensed with the California State License Board?
Do you offer lifetime/transferable warranties?
Are your installers bonded and certified?
Do you have liability insurance?
Are you classified as a window glazing contractor or just a general contractor?
Do you have references in my neighborhood?
How many years have you been in business?
Do you service what you sell?
Do you have factory-trained installers?
Do you buy factory direct?
Are you a Circle of Excellence Andersen Dealer?
