I'm a renter - how to FIX cracked bath/shower/walls & window ?

Jma what are the walls made of?

Jma, I would ask the landlord to take care of this. Unless you caused the damage, I would expect that this would be fixed or I would put the cost of the repairs in escrow (and deduct that amount from the rent) until it is fixed. Damages or issues with health and safety features (a shower and windows are both) are legitimate reasons to withhold rent until corrected or replaced.

was this damage done before you rented the space or after? you should notify your land lord. they are responsible for the repair- only if you noted it on the move in day check list. if you didn't note it, you'er going to notify the land lord and most likely, they will pay a pro to fix it. with you picking up the tab for the repair. rental units can be inspected periodically, if your land lord does nothing you can call your local housing authority. if hey find the place in violation, the land lord has x amount of days to make repairs.

don't do anything about fixing, until the report comes back.

i spent 1 year managing an apt. building........never again.

This is NOT your responsibility unless you caused the damage. Get it fixed and then deduct the cost of repairs from your rent. In most (maybe all?) states it should hold up in court. I'd check it out.

Not sure where you live so can't speak to laws in your area. I know that in my area renting from a person is different than renting from an apartment complex. If your landlord believes the inside is your responsibility, you may be able to deduct the cost of grout, tiles, etc. from your rent as long as you provide a receipt. The sweat equity is on you but the physical - permanent - improvement to property is on landlord.

I would think that if the faucet is broke then the landlord should have fixed it. Landlord never jump to fix anything and now he knows you can fix stuff so he is taking advantage. BTW don't use the tub and shower until the caulk and grout is fixed or the wall behind will get wet and the tiles will end up falling off. Some of that looks like black mold and I would think that he should cover that. You are in a tough spot right now with wanting things fixed and the landlord not fixing.

I owned a 3 family house for 23 years. Yes...I would have been responsible to repair and maintain that bathroom!! By no means should the tenant have to deal with the mess and the expense. If it was that way when you looked at the unit then the person showing it should have said it would be repaired before you moved in. I think a maintenance worker for the landlord needs to come in and take a look. Good luck with this!
