After remodeling my bathroom floor isn't level. Do I ask for compensation?

Factual Questions

Hi, we just had a reputable company add a bedroom, bathroom, and 2nd floor laundry room above our garage. The construction is almost over, but after they installed our two-sink vanity, it’s become obvious to us that the new floor isn’t level because 1) Our project manager said it wasn’t level, 2) There is a gap of between .5 and 1 inch between the floor and the bottom of one side of the vanity, and 3) The person installing the pocket door between the toilet and the sinks said the floor wasn’t level.

Assuming that they can get everything to cosmetically look good by covering up flaws with molding, etc., does this dimish the value of the addition? Do people usually ask for compensation when a floor isn’t level, or is it a fairly common occurrence. This is a brand new part of the house, and they pulled up the roof of the garage as part of putting the addition in, so it seems to me they had the power to make the floor level. Basically, how big of a deal should I make out of this?

Thanks in advance.

I would check the level of the floor side to side and end to end. A difference of more than 1/4" might be passable, but 1/2" woud be excessive in my view. Depending on floor covering they could build it up with leveling compound/cement.

A job that doesn’t pass inspection may not pass inspection by a prospective buyer somewhere down the line.

It’s visibly off? I’d raise a big stink.

Unless they’re planning for the addition to sink on one side soon, or there’s a floor drain, there’s no reason they couldn’t have gotten the framing level. If they couldn’t get the framing level, there’s no good reason they couldn’t shim things and get the subfloor (the plywood) level. If they couldn’t get the subfloor level, see what I’m getting at? With each layer of construction, there are opportunities to fix goofs in the underlying layers.

1/2 to ONE INCH? That’s a lot in the space of a 2 sink vanity. A real lot.

Have you layed a level on it? Perhaps the vanity is messed up. How out of level is the bedroom?

If the vanity is in, I assume the drywall is up?

It’s built over your garage. Was this a room before? Living space?

It sounds to me that they needed to ‘sister’ some new joists onto the existing ones to get things level before they set the floor.

Speaking as a GC-that measure of slope is not acceptable. The lead carpenter missed something, bigtime. I could not look the customer in their face and ask for payment with that degree of error. 1/16" over 8 feet is one thing, but what the OP describes is beyond that.
