What make & model is your new water heater?

Definitely use the LED bulbs but be sure that they are dimmable. The light output is much, much better than any other type of bulb. I know that they are more expensive but the CFL-type bulbs burn out much too quickly.

I wholeheartedly agree with Susan, wood behind a stove is a safety hazard.

If they were included, file a suit in small claims which you may win but never collect. Give the builder a final warning, in WRITING (email or certified), that you will be going online and posting comments about your negative experience.  

I agree, no less than 4/12 but the sheathing must be layered 100% with Ice & Water memebrane first.

No need for s econd mositure barrier which is what the paper-face is. Just roll out unfaced insualtion atop the existing. Or, as an option, rent a blower and use loose-fill insulation. 

Who is the builder sub-contracting the work to? THere are companies that do nothing but gutters. THere are also siding companies who handle the gutters. 

This is a project I know we can help you complete. PLease call me at 440.974.8082 so we can discuss the project in further detail.

Thank you,

I would build a stud wall and get rid of the recessed niche. Once done you will have plenty of support in securing the TV mount.
