Repair Cabinet with Cut-Out Side Wall and Cut-Out Back

Side and Back Panel of Cabinet Had to be Cut Out to Access Behind

A cabinet blocked access to something where a service call to fix something else, resulted in the need to cut through the cabinet. Unfortunately, that service call did not include the repair of this cabinet after the fact. However, fortunately for you and me, is that I get to be productive and fix something, and you get the opportunity to see some ideas on how to fix something like this, if you are looking.

A quick examination of the cut out boards, revealed that they are 3/4" plywood, which led to the thought that the use of pocket holes could potentially be used to reattach the cut out cabinet wall and back, back onto the cabinet.

Notes on How to Repair a Cabinet Where a Side and Back Panel Has Been Cut Out

Assess the condition of the interior cabinet, cutout wall, and cutout back - as well as the ability to accept pocket holes.
Develop plan of action, take notes, and maybe produce a checklist to follow the steps.
Looking at the closer view of the back panel appears to be an unpainted, which means that side wall butted into the back, which means, I can pocket hole attach the side panel to the back panel.
The back cutout cabinet panel appears to be 1/4" or less in thickness, but both ends appear to be reinforced with 3/4" thick plywood. We can use pocket holes to reattach on both sides of the back, but we are also considering to reinforce the middle of the back panel, top and bottom using some custom cut thin strips of wood, using a 18 gauge brad nailer using 5/8" brad nails.
Then, the left cut-out cabinet wall is fully 3/4" in thickness, we should be able to put pocket holes on both sides, top, and bottom.
If everything feels secure, and you're okay with it unfinished looking, we can sand and clean up.
Phase 2: Finishing and Polishing - Use some wood glue and pocket hole plugs to plug up and fill the pocket hole screw holes. Allow time for glue to dry.
Fill all void edges with wood filler. Then allow time to dry.
After initial drytime, use flush cut saw to flush cut all pocket hole plugs.
Do quick light sand (maybe 200+ grit), maybe using manual hand sanding sponge. Then reapply more wood filler if desired or needed.
If added more wood filler, do another light sand and clean wipe down.
If ready and done, can be ready for primer or paint to complete the interior cabinet wall and back repair.

Estimated Cost

$0-40 USD

Relatively inexpensive here if all you are using all consumables that you may already have - it could cost you nothing out of pocket.
On the other hand, if you need to buy every consumable, it could likely run up to around $40 USD easily.

Estimated Time

30 Minutes to Few Days

Depending on Form and Function. If only concerned with Function (Stabiilty and Time Savings Efficiency)- it could be a very fast job. However if additionally looking for Form too - Look to Plug, Fill, Sand, and Painting, as well.

Estimated People

1-2 People

This task can be completed by a single individual, however it's always nice to have some help.

Repair Water Damaged Rotted Framing

Bathroom Renovation Revealed Water Damage

I started on a journey to complete major renovations on my condo that was built in 1969 - and so I also decided to document some of the work, along with taking notes publicly to share with you all, in hopes that it may be of some value to you.

The bathroom was one of the primary rooms that desperately needed repairs and upgrades as the bathtub was all chipped up, shower tiles were dirty, moldy, and cracked in so many places, the toilet was cracked in multiple places, and the vanity probably had 30 layers of paint and wallpaper on it, along with the walls too. And just a plethora of everything was wrong with the bathroom. Needless to say, the easiest thing was to just start over, from the beginning.

Completely gutting the bathroom revealed many atrocities in the original build out, but I believe that is just something to be expected in this day and age. Granted, the bathroom technology back in 1969 in the USA was certainly not as good and standardized as they are now, in 2025. Not to mention, perhaps some maintenance along the way could have prevented some of the current existing water damage to the sill plate along the framing.

I'm not exactly sure when and how the water leaked back there, but the damage could have likely been caused from overflowed water from the vanity counter over multiple days, weeks, and years - or perhaps leaky pipes over years dripping over the sill plate - it was behind the vanity, under the sink, and behind the wall, of course. Nevertheless, I think likely the water damage could have been done prior to my purchase of the property The area had now turned dark, crumbly, and weak, no longer offering any structural support.

This rotted wood certainly needs to get repaired and reinforced before any other work continues in the bathroom renovation.
