Arched doorways were popular in Phoenix homes built from the 1970s through the 1990s — you see them constantly in Ahwatukee, older parts of Chandler, and mid-century Glendale neighborhoods. They were a design trend that felt upscale at the time. Now a lot of homeowners want them gone. The clean lines of a square or rectangular opening look more current, photograph better when listing a home, and work better with modern trim styles.
The good news: removing an arch and converting it to a square opening is absolutely doable. The less-good news: it's not as simple as it looks, and the final result lives or dies on the framing, the drywall work, and the texture match. If you're in Phoenix and considering this project, here's what you're actually getting into — and why this is a job worth hiring a licensed drywall contractor for.
Planning the framing layout before any drywall is cut
Arches in residential drywall aren't structural. They're a finish detail — a curved piece of drywall (typically flexible 1/4-inch drywall or a pre-bent arch form) attached to light framing at the top of the opening. They have nothing to do with load-bearing; the structural header sits above them, doing the actual work.
This is important to understand because it means removing an arch doesn't affect the structural integrity of the opening. You're working with finish materials and framing — not anything load-bearing. That said, the opening framing still needs to be evaluated. Some arched openings were framed with rough-cut lumber that curves — those need to be reframed square before drywall goes on. Others have straight framing with a curved drywall piece attached — those are more straightforward.
The distinction matters for estimating the scope and cost of the job. A contractor needs to see the existing framing before they can tell you exactly what's involved.
The first step is carefully removing the existing arched drywall. This means cutting away the curved section and any flexible drywall that forms the arch. Depending on how the arch was originally installed, there may be metal bead, wood backing, or a pre-formed arch form that also needs to come out.
On older Phoenix homes, the arch may have been plastered or built up with multiple coats of compound — thicker than a typical drywall finish. That adds material to remove and can widen the patching zone once it's gone.
The framing inside the opening is exposed at this stage. If it's already square (just the drywall curved over it), you're in good shape. If the framing itself is curved or irregularly cut, it gets reframed before anything else happens.
Having the right materials on hand before the first coat goes up
If the framing needs to be squared, a contractor will add blocking or sister studs to bring the top of the opening to a straight horizontal line. This is straightforward carpentry — nothing exotic — but it needs to be done right. Framing that's even slightly out of square creates visible problems in the finished drywall: corners that don't meet cleanly, tape lines that shift, or trim that gaps on one side.
The height of the new square opening is set at this stage too. You can choose to keep the opening at the existing arch peak (which gives you maximum height), or drop it slightly to a standard door height if you're planning to add a door or trim. That decision should be made before framing, not after.
Once the framing is square, new drywall goes in. For the sides of the opening (the "jamb" faces), this is typically a narrow strip — often 4 to 6 inches wide, matching the wall thickness. For the top of the opening, a flat horizontal piece replaces what was curved.
Corner bead goes on all exposed corners — the outer edges of the opening where the drywall meets the room. Metal or vinyl bead creates a clean, durable edge that takes compound well and holds up over time. In a doorway that gets regular traffic, the corners will get nicked occasionally — bead makes that damage minor instead of structural.
Then comes taping and multiple coats of joint compound. This is where a lot of the skill lives. The new drywall patches need to be feathered into the surrounding wall so the transition disappears. Any existing compound or paint buildup on the walls around the opening needs to be accounted for. This typically means at least two coats of compound, sanded between coats, with a final skim if needed.
The drywall finishing process on an arch conversion is more involved than a simple patch because the affected area is large. You're essentially refinishing portions of two or more walls around the opening, not just filling a hole.
This is where arch conversions either look seamless or look like a patch job. Arizona homes almost universally have textured walls — orange peel, knockdown, skip trowel, or Santa Fe finishes. Whatever your home has, the new drywall needs to match it exactly.
Texture matching is a skill that takes time to develop. The variables are significant: spray pressure, material consistency, gun distance, ambient temperature and humidity, and how existing texture has aged. Phoenix's heat accelerates compound drying, which changes how texture behaves compared to other climates. A contractor who does this work regularly in the Valley has dialed in those variables. Someone who doesn't do it often will struggle to get a blend that holds up under raking sunlight — which is the harshest test of texture work there is.
You can also ask whether the contractor does a full-wall texture application (rolling compound over the entire affected wall and re-texturing) versus a spot blend. A full-wall approach is more labor-intensive but produces a more seamless result, especially if the existing texture has faded or the repair area is large.
A clean square opening reads as a design feature, not a repair.
A straightforward arch-to-square conversion — where the framing is clean and just the curved drywall needs to go — typically takes two days. Day one: demo, any reframing, new drywall hung and first coat of compound. Day two: sanding, second and third coat, texture, prime. Paint happens after the contractor is done, either same day or as a separate appointment.
If the framing needs significant work, or if there are multiple arches (a hallway with several arched openings, for example), add a day. If a full-wall texture approach is used, factor in additional drying time — especially in summer, when the AC fighting Arizona heat can drop indoor humidity and accelerate drying faster than expected.
This is not a one-day job if you want a quality result. Contractors who promise to demo, patch, texture, and prime in a single day are either skipping coats or not letting material dry properly. Rushed compound work cracks. Rushed texture work shows.
Some homeowners convert an arch to a square opening so they can add a door where there wasn't one — closing off a room for privacy, adding a barn door, or installing French doors. If that's the plan, the rough opening dimensions need to be set correctly at the framing stage. Door rough openings follow standard sizing (typically 2 inches wider and taller than the door slab). The drywall contractor coordinates the opening size with wherever the door is coming from. The door installation is typically a separate step after the drywall is complete and primed.
If you're planning to add a door, say so at the beginning. It changes the framing approach and the final dimensions of everything.
For most Phoenix homeowners, yes. Arched doorways date a home visually. Square openings read as clean and intentional. If you're preparing to sell, buyers and agents consistently prefer updated interiors, and an arched hallway can feel like a renovation flag. If you're staying, you're looking at this every day — living with something you don't like is its own cost.
The project lands somewhere between a straightforward patch repair and a full room remodel in terms of scope. Done right, the seam between old and new disappears entirely. Done wrong, you're looking at visible patch lines every time light hits the wall at an angle.
