Terrible restoration after plumbing replacement - How should I fix it?

[Vickevoff]

Hello,

I have a condominium that underwent a plumbing renovation before I bought the apartment. After a previous plumbing job with a really poor restoration, there are now large holes in the lower and upper corners of the kitchen. What's the easiest way to repair these holes?

I'm thinking of spraying in some expanding foam and then applying a thicker layer of joint compound, thinking that the foam will provide some resistance to press the compound onto. Does this sound like a good solution or how would you have done it?

Exciting.......what's inside the cavity if you shine a light in? Feels more like something for the association to fix that?

Exactly. That shouldn't be accepted. They should come back and finish it.

I haven't looked too closely, but a drainage pipe is visible in the upper corner and in the lower corner, I suspect my own pipes to the bathroom run.

The pipe replacement was done about 10 years ago, i.e., 8-9 years before I bought the apartment. I feel that I don't necessarily need to involve the association since it was done so long ago, and it's probably something I can relatively easily fix myself.

Hi,

I have a condominium that underwent a pipe replacement before I bought the apartment. After a previous pipe replacement with really poor restoration, there are now large holes in the lower and upper corner of the kitchen, how can I best repair these holes?

I'm thinking of spraying in some sealant foam and then applying a thicker layer of house fixer, thinking that the foam will provide some resistance to apply the fixer onto. Does this sound like a good solution or how would you do it?

I would choose sealant foam/fixer.
It can take weeks/months/years to sort out neglect from a previous contractor.

Ah, I understand how you're thinking.
I would have filled it in with plaster. Foam filler is a pain to work with, and there's a risk of damaging the construction when you fill a deep hole like that.

Hello,
I would probably buy a backer rod or use fiberglass insulation to have something for the plastering to adhere to.

As you mentioned, there's no point in talking to the association since this concerns the apartment's surface layer, and it's usually the condo owner's responsibility for maintenance. You bought the apartment as-is and therefore accepted this defect, which is not something the association can pursue as a warranty claim against the contractor now.

Foam sealant should not be used, it is flammable.
Use mineral wool and gypsum plaster.

If the fire protection is compromised, it is the association's responsibility...

there is fire foam BRANDSKUM SIKA BOOM 420 FIRE 750 ML (bauhaus.se)

but I would have used insulation and repair mortar

I would have used plaster mix any day of the week. If mixed correctly, it becomes relatively "viscous" and can be applied without major problems even on the ceiling. The advantage of plaster mix is its quick setting time, I can usually refill the hole after an hour, by then it has set. So several small batches with plaster mix do the trick, easy to sand and easy to mix. If I don't need much, I mix with a "paint stir stick" in an old yogurt tub/ice cream tub.
