A wall oven only sits right when the platform carries its weight at the exact height
A single wall oven runs well over a hundred pounds and a double runs far more, all of it hanging in a tall cabinet at one exact mounting height. Set that height a half-inch off and the door binds; rest it on something that flexes and the whole face sags. We build the load-rated platform, dial in the height, and make the controlled two-person lift.

Wall ovens are the appliance most likely to fight the cabinet. They weigh well over a hundred pounds for a single and far more for a double, they hang in a tall cabinet at one exact mounting height, and most of that load rests on whatever platform sits below the unit. Set the platform height wrong and the door binds against the cabinet face; build it light and it flexes under a double until the gaps open up. We measure the new unit against the opening, build or rebuild the platform to the manufacturer's height with stock rated to carry the load, square the cutout, and make the heavy two-person lift so the oven seats clean, level, and resting on something that holds.
The problems we actually solve
The platform height is off by a fraction
The mounting height isn't a suggestion — it's the dimension that sets where the door swings and how the flange meets the face frame. A platform set even a half-inch low drops a heavy door into the cabinet below; set high, the controls sit awkward. We set it to the installation sheet and check it with a level before the oven goes anywhere near the opening.
There's nothing under it rated to carry the weight
An oven resting on a couple of pulled-out drawer rails or a thin scrap of plywood is a sag waiting to happen. We build a load-rated platform on cleats so the unit's weight transfers into the cabinet box, not into the trim and the door gaps.
The lift goes wrong solo
Trying to muscle a wall oven into a chest-high opening alone gouges the face frame, scratches the unit, and risks a dropped oven. We bring two people and seat it controlled, with the cabinet edges protected.
Wall Oven Installation, done properly
Confirm the cutout against the new spec
Before anything comes out, we check the new oven's required cutout — width, height, and depth — against the existing opening so we know exactly what carpentry the install needs.
Build the support platform to the mounting height
A plywood platform and cleats sized for the unit, set with a story stick and level to the exact height the manufacturer calls for, so the oven's flange lands flush and the door swings clear of the cabinet below.
Resize and square the cutout
Width and height trimmed to the spec for a single, double, or oven-microwave combo, with cuts kept straight and dust controlled at the blade so the trim kit covers a clean edge.
Coordinate the electrical
Most wall ovens land on a dedicated 240V circuit; combos and some singles may run 120V. We confirm the connection point and breaker fit the new unit and bring in a licensed electrician when the circuit needs to change.
Make the two-person lift and seat it
We hoist the oven onto the platform, slide it home, and anchor it through the face frame so it can't walk forward when the door is loaded.
Align trim and check the level
Trim kit and flush surround set even on all sides, the unit leveled front-to-back and side-to-side, and the door gap checked top and bottom with a feeler gauge so it sits tight to the cabinetry.
What we account for
-
Cutout specs vary by model
Two ovens of the same nominal size can want different openings, and double ovens stack tolerances. We work from the specific unit's installation sheet, not a generic size, so the cutout and platform match the oven that's actually going in.
-
240V circuit and connection type
Many wall ovens are hardwired to a 240V circuit, while some pull a cord-and-plug or run at 120V. The breaker size, wire gauge, and junction box have to match the new unit — worth confirming before delivery day so the install isn't held up by a wiring change.
-
Height, weight, and door clearance
Platform height sets the door height and how the oven vents above. Set it too low and a heavy door drops into the cabinet face; too high and the controls sit awkward. The platform also has to carry real weight, especially for doubles, without flexing over time.
Why the carpentry and the install have to happen together
The thing that sinks a wall oven swap is the platform: the new unit's mounting height rarely matches what's under the old hole, and a platform that carries a single without flexing can sag under a double. Getting that right means building to the manufacturer's height with load-rated stock and then seating the oven onto it the same day — the people who frame the platform are the same crew who make the lift and check the door gap, so the height that gets built is the height the oven actually needs.

- 01
Assess & measure
We start with the appliance spec sheet and the opening it has to live in — width, depth, height, the face frame, utilities, and the cabinet around it. Most fit problems are decided here, before a single tool comes out.
- 02
Protect the kitchen
Floors, countertops, and finished cabinet faces get covered, padded, and taped off first. Blue tape on the edges, moving blankets and ram board on the floor, and a vacuum staged for dust control.
- 03
Install & fit the cabinet
We set the appliance — and when it does not drop in clean, we modify the cabinet to make it: resizing the opening, building a support platform, adding filler strips, or aligning panels and trim for an even reveal.
- 04
Level, test & clean
The appliance is leveled, secured, and anti-tip hardware set where it belongs. We test operation, check every reveal and gap, then vacuum and wipe down so the kitchen is ready to use.

Wall Oven Installation: common questions
Can you install a wall oven that's a different size than my old one?
Yes — that's one of the most common reasons people call us. When the new unit's cutout doesn't match the old opening, we resize the cabinet cutout and rebuild the support platform to the new spec, then set the oven in the same visit instead of leaving you with a hole the appliance won't fit.
Do you install double ovens and oven-microwave combos?
Yes. Single wall ovens, double ovens, and oven-microwave combos all install on the same principle — a platform at the correct height and a cutout matched to the unit — but doubles weigh more and stack tolerances, so the platform and the lift both get sized for that.
Will I need an electrician?
Sometimes. If the existing 240V circuit, breaker, and connection match the new oven, we can land it directly. If the new unit needs a different circuit, breaker, or junction box, we coordinate a licensed electrician so the wiring is done right.
Why does the support platform matter so much?
A wall oven hangs in a tall cabinet with most of its weight resting on whatever sits below it. Without a load-rated platform at the right height, the oven can sag, the door can bind, and the trim won't sit flush. The platform is what makes the install solid and keeps it that way.
How do I know my new oven will fit before it shows up?
Send us the model number, or have us out to measure the opening and check it against the unit's installation sheet — width, height, depth, mounting height, and the circuit. We'll tell you what the platform and cutout need before delivery day, so the oven isn't sitting in your garage waiting on carpentry. Call us and we'll walk through it.

Cabinet Modification
When an opening is a half-inch too tight or a face frame is in the way, we modify the cabinet so the appliance fits — square, level, and damage-free.

Bosch oven installation was flawless. The tech explained everything — gas line connection, ventilation, how to test before first use. Really went above and beyond.
Professional from start to finish. Installed a built-in microwave and wall oven. Everything was level, sealed, and tested before they left. Couldn't ask for more.
Had my new Samsung washer and dryer installed same day I called. The tech showed up on time, was professional, and even leveled the machines perfectly. No leaks, no issues. Highly recommend for anyone in the South Bay.
Finally got my LG refrigerator installed after waiting on another company for 2 weeks. These guys came out the next morning. Hooked up the water line for the ice maker, cleaned up after themselves. 5 stars.
Installed my new dishwasher in under an hour. The old one had a weird fitting issue and they worked through it without charging extra. Honest and fast.
Called at 9am, tech was at my place in the Mission by noon. Installed a new microwave over the range. Clean install, no drywall damage. Will use again.
