Hire someone reputable to redo all that properly with proper cover plates, proper laundry wall set up etc. Your flex hose for the dryer should be solid once it is in the wall and even better is solid all the way.

Flex dryervents are not to code, the water line shut offs have to be reachable no matter how fancy the laundry room is. Not sure about the 220 and the plugs on the upper wall what are they for ? Yes they need backplates . Get a proper installer before you really have issues.

Unfortunately, you need a reputable contractor to come in and re-do the job correctly.

Reading your comments this morning and it’s so hard to hear. It was a reputable contractor who did the job unfortunately and after a

All that money spent idk what to do now

You unfortunately will need to spend some more to do this right .

It looks as if it was a concrete wall, maybe a basement, and a new wood framed wall was furred out, but none of the MEP was brought out with it. It appears this project is beyond the abilities and knowledge of the person who did it. Things more in line with proper install and would qualify for a "pinterest" look:

• The 120V outlet needs an extension ring;
• The dryer transition duct may be flexible (but a very poor choice), but has to stop at the wall and mate to a rigid 28ga sheetmetal duct from the wall face to the exterior discharge hood;
• The gas line may be flexible from the shutoff valve, and I don't believe the way the valve is in the access hole contradicts code. However, a better install that works perfect here would use a gas outlet box;
• The washer drain line doesn't appear to be durable and fastened (it may blow out) going into a waste pipe parallel. And, I can't see the piping behind the wall, but a minimum height and size of standpipe must be there. Also, if the water supply and waste pipes were to be adjusted a little, another instance of a washing machine outlet box would have worked with the furred out wall.

So I did contact the contractor back. He is claiming it is a mechanical room so it is up to code for that area. But I completely disagree but he is coming back to fix it or at least sending licensed plumber and electricians and I almost want to say show me your license ID when they walk through the door because idk who to believe anymore

Your contractor is just making excuses, by this work he doesn't actually know anything. You have specific codes that apply in various ways to mechanical rooms and laundry rooms. It is not a matter of just "complies because it is a mechanical room." For instance, in the U.S.:

• NEC 314.20 would require a flush mounted box be no deeper than within 1/4" of the drywall finish (hence an extension ring);
• IRC M1502 calls for the in-wall sheetmetal duct and limits the transition duct (hence the foil slinky must be pared back);
• IPC 406.2/802.4.3 requires the washing machine drain in a standpipe with air gap (hence I doubt the piping inside the wall is right considering his aptitude);
• IMC 409 governs the gas shutoff valve access, that may be ok in terms of explicit code, but maybe not with an inspector though;
• IRC G2407 requires combustion, ventilation, and dilution air for gas appliances;
• If this is an exterior wall or any wood on concrete, IRC R317 requires that wood in contact be treated, and IRC N1102 requires insulation in a specific method. If there is a gap between the new wood framed wall and original wall, IRC R302.11 requires fireblocking.

Building something seems easy, but it is not even for a simple task. Professionals providing those services up their game, homeowners that want things right pay professional prices, sign contracts that hold those professionals accountable, and arm themselves with information so they are not a deer in headlights.

Update on the laundry room. He completely took the tape off the dryer vent and installed drywall. It’s just sitting in the wall now. I had to cut a bigger cutout to attach it properly before I can finally start my laundry. Knowing I’ll put my own flooring down. Didn’t even lay a tarp and compound mud all over the floor when they repatched. Also fixed electrical but guess what. Somehow killed the outlet on the other side of the wall which has our tv printer and mini freezer!!!!!! Not calling them back this time to fix anything.
