New Construction Rough Mechanical without Windows - pro advice needed

Jsmmao's picture

 Hello Everyone,

I am in the process of building a custom home and the builders have had some delays in ordering select materials. Mainly the windows and doors. The house is fully framed and roofed but we are waiting for the windows and doors to arrive soon. They decided to install all rough mechanical (electric, plumbing, HVAC) while we wait for the windows to arrive. I am not a builder buy any means, but I know they usually don't do this stage until the windows are on. With that being said, my question is: can having the rough mechanical installed prior to the windows and doors being installed have any negative effects? Also, I noticed that the plumbing that goes to the roof still doesn't have a boot over it so water can penetrate through the gaps and get that portion of the home wet. Other than that, doesn't seem to be any other leaks and there are porches around the whole home.

Any help would greatly be appreciated. I am also scheduling and independent inspector to do a pre drywall inspection to make sure everything is functional. My wife and I are very concerned however and was hoping for some insight.

So long as the window and door openings are covered with plastic or some such to keep out the dust and bugs, what do you think is going to happen to the mechanicals?

Water in ductwork or furnace?

If they're looking for something to do, how bout the roofing?

I'd say its not untypical. Window and door makers are behind demand and taking longer than normal. Builders are trying to keep jobs moving and customers happy so they do what they can do which is roughs. Obviously no harm to the plumbing and not much p[ossibility of harm to the electric. I assume the roof is dried in? In my experience doing the AC at this stage is not uncommon although the threat of theft is probably the builders biggest concern. I wouldn't be worried about it if it were me. I've never seen a roughed in house with plastic over any opening at any point in constrution and it would make no difference anyway. Water coming in around the vent will mostly run down the pipe and make a small puddle on the floor.

Thank you all for your insight. Yes, I was mostly concerned about the HVAC and electrical. Wasn't sure if the water could damage it and of course theft. They do not have anything covering the windows so they're open to the elements but not much rain gets in. The roof is shingled so keeps all the water out except for the few puddles from the open plumbing that's missing the flashing/boot.  Thanks again
