Our Materials

Built for Southern California

Industry-Leading Waterproofing Partnership with OSI

We’ve partnered with OSI to ensure every installation provides maximum protection against moisture intrusion. Our OSI-certified installation methods have been specifically developed for Southern California’s unique climate challenges, creating a superior seal that protects your home and maximizes energy efficiency.

Premium Installation Materials Built to Last in San Diego

Every installation includes only the highest-quality materials selected specifically for your home’s needs and our coastal environment. From corrosion-resistant fasteners to marine-grade sealants, we use products built to withstand San Diego’s salt air, UV exposure, and temperature fluctuations.

Tailored to Your Home’s Unique Needs & Your Preferences

We don’t believe in one-size-fits-all solutions. Our material selection is tailored to your individual needs and your home’s specific requirements, from the type of exterior cladding to the level of sun exposure. Every home presents unique challenges, and we adapt our approach accordingly.

The 360 Process

Step 1: Initial Consultation

Your journey begins with a comprehensive in-home consultation where we:

Determine the Best Products for Your Home and Needs: Our product specialists evaluate your specific requirements to recommend the ideal windows and doors from our curated collection of premium brands.

Determine the Best Installation Method for Your Home and Needs: Step by step, we’ll show you how the installation will be completed using our OSI-certified methods. We’ll explain whether retrofit or new construction installation is best for your situation.

Take Measurements: Initial measurements are taken to ensure accurate pricing and identify any unique requirements.

Make Detailed Selections: Together, we’ll finalize every detail on any hardware, colors, and options for your selected brand.

Build Your Quote: Your product specialist will build the quote and present pricing along with payment options.

Step 2: Technical Measure

Final measurements are taken by a qualified member of the team to ensure absolute accuracy before ordering.

Step 3: Ordering

Our multi-step verification process during our ordering procedure ensures we get it right the first time.

Step 4: Installation Day

On installation day, our team takes care of everything:

We Protect Your Home: We treat your home like it’s our own, taking careful measures to protect your property throughout the installation process.

Professional Installation: We follow OSI-certified methods for proper installation and waterproofing.

Complete Clean-Up: We remove all debris and the old units, leaving your home clean and organized.

Step 5: Quality Inspection & Walkthrough

After installation is complete, we perform a thorough quality inspection and walkthrough with you to ensure everything meets our high standards and your expectations.

Step 6: Follow-Up and Warranty Support

Our relationship doesn’t end at installation. We provide ongoing follow-up care and warranty support to ensure your complete satisfaction.

Installation Methods

Retrofit Installation

Perfect for existing homes, retrofit installation involves replacing your old windows and doors while preserving existing frames and finishes when possible.

New Construction Installation

New construction installation involves complete frame replacement and can be used for both new builds and existing homes.

Important Note: New construction can also be done on existing homes. To determine which installation method to use, our team will consider your preferences and the needs of the home itself. We go over all of this during the consultation to ensure you make the best choice for your situation.

Frequently Asked Questions

How long does the entire process take from consultation to installation?

The timeline varies based on product selection, project scope, season, and current demand. We’ll provide a specific timeline during your consultation so you know exactly what to expect for your project.

What’s the difference between retrofit and new construction installation?

Retrofit installation replaces your old windows and doors while preserving the existing frames and interior/exterior finishes when possible — it’s typically faster and less invasive. New construction installation involves complete frame replacement, offering a fresh start that can address any underlying structural issues. Both methods can be used on existing homes, and we’ll recommend the best approach based on your home’s condition and your preferences during the consultation.

Do you really use OSI-certified installation methods for every job?

Yes, absolutely. Every installation our team performs follows OSI-certified methods specifically developed for Southern California’s coastal climate. This isn’t just a marketing claim — our installers are trained and certified in these techniques to ensure maximum protection against moisture intrusion, air leakage, and the harsh effects of salt air and UV exposure.

What happens if measurements are off or something doesn’t fit correctly?

Our multi-step verification process is designed to prevent this. We take initial measurements during consultation, then a qualified technician returns for a final technical measure before we order anything. This double-check system ensures absolute accuracy. In the rare event an issue arises, we handle it immediately at no additional cost to you.

How do you protect my home during installation?

We treat your home like our own. Before any work begins, we carefully protect floors, furniture, and surrounding areas. During installation, we contain dust and debris, and we complete a thorough clean-up before we leave, removing all old units and installation waste. 

What’s included in the final walkthrough?

After installation is complete, we perform a comprehensive quality inspection with you present. We’ll show you how to operate your new windows and doors, explain care and maintenance, review warranty information, and ensure every detail meets both our standards and your expectations. You’ll have the opportunity to ask questions and address any concerns before we consider the job complete.

What kind of follow-up support do you provide?

Our relationship doesn’t end at installation. We provide ongoing follow-up care to ensure you’re completely satisfied and help with any questions that arise. We also manage all warranty support — so if you ever need service, you work directly with us, not the manufacturer. We handle the coordination and make sure any issues are resolved quickly.

Can you match my existing window or door style?

Absolutely. During your consultation, we’ll work together to select products that complement your home’s architectural style. Our curated collection of premium brands offers extensive options for colors, hardware, grid patterns, and finishes. Whether you’re matching existing windows or creating a whole new look, we’ll help you make selections that enhance your home’s aesthetic.

What if I need to reschedule my installation?

We understand that life happens. If you need to reschedule, just contact us as soon as possible. We’ll work with you to find a new date that fits your schedule. We ask for reasonable notice to avoid unnecessary delays in your project timeline.

What payment options do you offer?

We offer multiple payment options to fit different budgets, including financing plans. Your product specialist will present all available options during your consultation, along with any current promotions or special offers. We believe in transparent pricing with no hidden fees.

How far in advance should I schedule my consultation?

We recommend scheduling as soon as you’re ready to start exploring your options. Keep in mind that the entire process may take several weeks, so planning ahead ensures you can complete your project on your preferred timeline.
