Might be worth it to use the metal door/window blocks that you generally have to hire a company for. 

You can confirm that they met all requirements, if that is their concern, but ultimately another applicant was chosen. 

I used Bear Metal Welding & Estrada Fence in Evanston (BP doesn't allow me to post the phone number, but you can google it) in the past.

In addition to toilets, look at low flow shower heads and aerators on the kitchen sinks (the metal ones you screw on and can swivel). 

[5] Will you use colored standing seam metal on the porch roof to make it look modern or shingles?

We just bought a place and are looking for some data points/recommendations a) Attic clean-up/sterilization and b) 200 amp main panel upgrade in the San Diego, areaThe quotes we received are basically insane, even accounting for the recent inflation... one guy wanted ~$3500 to clean/sterilize/seal up two metal mesh openings (and that's including a $500 "discount" for doing it before Thanksgiving).

Check the coils and clean them.

Does anyone know a contractor in the Hudson County, NJ area that can quote me to remove metal/Iron bars from several windows in a Multi-family home? 

The two snakes/augers I have each have a "blunt" end of coiled wire, so I am not sure they will work once I get to the job site.
