Hello Houzz friends. We have a new build with 10ft ceiling on 1st floor. We currently have 5 1/4” baseboard as part of builders standard size and want to upgrade to 7 1/4” … the builder came back with labor up charge of 3K+. 1st floor is about 2000 sqft. This doesn’t even include material cost! I would’ve thought the labor to install a 5” and 7” would be the same so wasn’t expecting more labor charge. Does this make sense to you?
