What We Do

Creating New Openings That Work With Your Home's Structure

A new door opening or custom window opening installation is more than a cosmetic change. It involves precise structural work to ensure your home's integrity is fully preserved while the new space functions exactly as intended. Our team assesses load-bearing considerations, framing requirements, and finish details before a single cut is made. We serve homeowners in Placentia, Fullerton, Tustin, Santa Ana, La Habra, Orange Park Acres, and across the greater Orange County area, bringing the same level of artisanal precision to every project regardless of scope.

Why It Matters

Structural Door and Window Installation Done With Precision

When you invest in structural door and window installation, the quality of the execution directly affects your home's value, energy performance, and long-term durability.

Design Possibilities

Architectural Window Modifications Built Around Your Vision

New openings give you the freedom to rethink how your home looks and feels. From south-facing window walls that flood a living space with light, to wide pivot door openings finished in Accoya or Mahogany, to bay window cutouts with custom corbels, the design options are as varied as the homes we work in. Our architectural window modifications are planned carefully so the finished result looks intentional, not retrofitted. If you have a specific vision in mind, or simply want to know what is possible for your space, our team is ready to walk you through it.

Your Questions, Answered

Common Questions About New Window and Door Openings

  • What does the process look like for adding a completely new window or door opening to an existing wall?

    The process starts with an on-site consultation to assess the wall in question, including whether it is load-bearing. If it is, a proper header must be installed to carry the structural load before the opening is framed out. From there, the opening is cut, framed to the correct dimensions for the chosen door or window unit, and finished with appropriate trim and weatherproofing. Showcase Door & Window handles each phase carefully to make sure the structural work is sound and the finished result looks clean and intentional. Every project is assessed individually since no two walls or homes are exactly alike.

  • Can you handle both the structural opening work and the supply and installation of the door or window unit?

    Yes. Showcase Door & Window can handle both the structural opening work and the installation of the door or window unit itself. We work with a wide range of materials including Accoya, Mahogany, Alder, iron, fiberglass, and high-performance vinyl, so there are plenty of options depending on your design goals and budget. We can also install products you have already sourced yourself if you prefer to supply your own unit. Either way, the structural work and the final installation are handled with the same level of precision and care.

  • How do I know if the wall I want to open up is load-bearing?

    In general, walls that run perpendicular to your floor joists or that sit directly above a foundation wall or beam are more likely to be load-bearing. However, the only reliable way to confirm this is through a hands-on assessment of your home's framing. Our team evaluates this as part of the consultation process before any work begins. If the wall is load-bearing, we factor the appropriate structural support into the project plan. Skipping this step is one of the most common causes of costly problems after an opening is created, and it is something we take seriously on every job.

  • What types of door and window openings does your team work with?

    We handle new openings for a wide variety of door and window types, including pivot doors, French doors, bifold doors, sliding doors, bay windows, picture windows, south-facing window walls, and custom shape windows. Whether you are looking for a dramatic 50-inch wide pivot door entry finished in stained Accoya or a series of picture windows to bring light into a north-facing room, the scope of what we can create is broad. Our team serves homeowners across Anaheim, Villa Park, Brea, Irvine, Tustin, Orange Park Acres, and the wider Orange County area.

  • Could adding a new opening affect my home's energy efficiency?

    It can, in either direction, depending on how the opening is planned and what product is installed. A poorly framed or sealed opening can introduce drafts and heat transfer that raise your energy bills. On the other hand, a well-executed opening fitted with a high-performance unit, such as a window with dual low-e3R glass, can actually improve your home's thermal performance. We pay close attention to proper sealing, flashing, and insulation around every opening we create so that energy efficiency is not compromised. For south-facing walls in particular, the right window placement and glazing can make a noticeable difference in comfort.

  • How long does a new window or door opening project typically take to complete?

    Project timelines vary based on the complexity of the structural work involved and the type of unit being installed. A straightforward new window opening in a non-load-bearing wall can often be completed in a single day once materials are on hand. A larger project, such as creating a wide opening for a bifold door system or a south-facing window wall, may take several days to ensure the framing, installation, and finishing are all done correctly. During your consultation, our team will give you a realistic timeline based on the specifics of your project so you can plan accordingly.

  • Do you serve areas outside of Anaheim for new opening projects?

    Yes. While Anaheim is our home base, Showcase Door & Window serves a broad service area that includes Brea, Fullerton, Placentia, Orange, Villa Park, Tustin, Santa Ana, Irvine, Orange Park Acres, La Habra, and surrounding communities throughout Orange County. We also extend our services into parts of Riverside County and Los Angeles County. If you are unsure whether your location falls within our service area, reach out and we will let you know.
