Our experienced team oversees each project to guarantee that your new openings are structurally sound and meet your design preferences.

New or Modified Openings

For homes requiring window or door size changes, our construction team can modify the existing openings or create new ones to ensure the perfect fit for your new windows and doors, including:

  • Enlarging window openings to accommodate larger or panoramic styles, such as bay or picture windows.

  • Creating new patio door openings to provide better access to outdoor living spaces.

  • Installing new headers or structural framing to support larger door or window configurations.

Garage Fire-Rated Doors

In addition to window and door replacements, we also install garage fire-rated doors. These specialized doors are designed to meet building codes by offering enhanced fire resistance, creating a secure barrier between your home and garage.

Additional Services

We offer additional services to complement our full-frame window and door replacements. These services provide added convenience and customization to enhance your home’s functionality and style.

We offer pet door inserts for homeowners with pets as part of our new door installations.

Pet door installations are available only with new door purchases, ensuring a secure and proper fit.

We also provide storm doors with select new door installations for added protection and insulation.

For homes that need enhanced room ventilation, piston windows offer a smooth opening mechanism that provides excellent airflow and is easy to operate.

If you need glass replacement, it must be paired with at least one full-frame window or door installation to ensure a comprehensive service.

Frequently Asked Questions

What is your minimum job size?

There is no minimum requirement for the number of units per order! Whether you want to replace a single window or a hundred windows, we’re here to help you get the job done.

How long does a typical window or door replacement project take?

Most window or door replacement projects are completed within 1 to 3 days, depending on the size and complexity of the job. During your consultation, we’ll provide a more detailed timeline based on the specifics of your project.

What is a full-frame replacement, and why is it better than a retrofit installation?

A full-frame replacement removes the entire window or door, including the frame, while retrofit installations leave the existing frame in place. Full-frame replacements offer better energy efficiency, resolve issues with the old frame (such as rot or warping), and result in a more complete upgrade.

What types of materials do you use for window and door installations?

We offer high-quality materials from top manufacturers like Milgard and WinDor. Our windows come in vinyl and fiberglass options, while our doors are available in steel, fiberglass, and vinyl.

What is the warranty on your windows and doors?

The beauty of working with the top window manufacturers in the industry is the support you can expect before, during, and after installation. Our manufacturers offer industry-leading warranties. However, the likelihood that you’ll need to take advantage of these warranties is low.

We offer our exclusive Leak Armor warranty for added peace of mind. For more details on this comprehensive protection, please visit our Leak Armor warranty page.

Do you offer custom-sized windows and doors?

Yes, we offer custom-sized windows and doors to fit non-standard openings. Our team will measure your space and recommend the right products to ensure a perfect fit for your home.

Do you offer glass-only replacement?

We do not offer glass-only replacement unless paired with at least one full-frame window or door replacement. This ensures that your new glass is installed as part of a comprehensive, high-performance solution.

Do you handle repairs for existing windows or doors?

We do not offer repair services for existing doors and windows. We specialize in full-frame replacements, which involve completely removing the old window or door and installing a new, high-quality product for better performance.

Can I supply my own window or door for you to install?

We do not install customer-supplied products. Our installation service includes removing, supplying, and installing the window or door to ensure the highest quality and compatibility with your home.

Do you work on new construction projects?

We’re currently focusing our efforts on providing replacement windows only. The reason behind this is the difference in quality and structure of replacement windows vs. new construction windows. It’s often worth replacing new construction windows with retrofit windows to increase energy efficiency and durability. however, our doors can be installed anytime during your home’s lifetime. Reach out to our customer service team to discuss your circumstances.
