The biggest companies can roof a house for the price of the supplies if you go to a hardware store because of volume.

That's literally hours devoted to removing all the plates, scrubbing all the plates, listing the plates that are needed and buying new ones next time I'm at the hardware store, and then replacing all the plates (with outlet gaskets on outer walls). 

In addition to the services, any hardware such as a modem or router that goes along with utilities should also be owned and managed by the homeowner.

Cosmetic issues come next and it's up to you how you want to handle these items (i.e. paint, new cabinet hardware, etc). 

I have a local hardware store which I have an account with.

Some of the failure mechanisms are rusted connection hardware, crack treads, spalling from freeze-thaw cycle, and decay from moisture.  

Cut them some slack and open up your wallet.

That alleviated my concern about a failing unit while protecting my wallet from an unnecessary capital expenditure. 

You can probably get it at most hardware stores. 

The value add was through the rehab that consisted of a new roof, updated the fuse panel to a breaker panel, new LVP flooring throughout, minor bathroom updates and paint, repainting the entire interior, adding new hardware and paint to existing kitchen cabinets along with new countertops and sink, new stove and rangehood, and lots of overall minor deferred maintenance.
