Same with enclosing a garage, putting tile in the shower, installing quartz countertops.  

Give Home Depot a shot.Alternatively, see if you can find a pre-bullnosed granite slab supplier within driving distance.

Painted 100% of the interior and exterior window trim, replaced the front door, added tile floors in the bathroom and kitchen, painted bathroom vanity and replaced all fixtures, put in new quartz countertops on original cabinets, all new light fixtures, door knobs and handles throughout.

Mostly cosmetics - New kitchen & bath, flooring, new AC, tile, paint, fixtures What was the outcome?

Broken tile, cabinets hanging off the wall, dry wall holes, etc. 

Here is a quick scope of work: -New plumbing, electrical, roof, HVAC-Fixed foundation issues-Remediated termite damage-Added a bathroom and bedroom-Converted carport into a 2 car garage-New LVP flooring and tile floors in bathrooms-Full kitchen and bathroom renovation-High end finishes throughout (to match the area)-Converted to city water What was the outcome?

If given the option I would opt to replace it with luxury vinyl tile. 

I replaced the sum-pump and installed porcelain tile throughout the basement, just to make sure.

Many builders "and SMART investors" form "Builder/Investor Buying Groups" where they share subcontractors and suppliers to increase their collective purchasing power and CLOUT when it comes to having their jobs done when they want them.If I just had one kitchen sink to replace, the plumber may "get to me when he can", but if my team and I can keep a few of his crews busy month after month after month, I can pretty much count on him replacing that sink for me anytime I need it.And Remember, Economies of Scale applies not only to purchasing power, but KNOWLEDGE too!  

so I hired contractor  to remodel bathroom and he contracted it out to another contractor  who's cotracts bad contractors to to work.I had to have them gut the bathroom again  and do it again.it still wasn't done properly due to they put up drywall and they didn't even prime walls  so paint comes off,the tile is 2 diffrent colors when supposed to be all white,the drain pipe is not to code and looks like cap so I had to fire them.now he wants to be paid in full and said if don't will put lien on house .I don't feel that they completed the job correctly. there wasn't sign contract with this contractor .I would be willing to pay for one set of materials  but nothing  more since I have to find another  contractor  to do it correct .what are my options ?
