I know a tile guy in our local neighborhood that seems great, i just havent used him.

Suppliers should carry you 60 days.

The tiles has to wrap around all the way to the window where it is just tiles-caulk-window. 

The scope of repairs include: complete renovation of master bathroom, kitchen, and guest bathroom.I spent about $1,700 on materials for the master bathroom (vanity, lighting, tile, grout, 2 medicine cabinets, cement, drywall, etc.).

Any recommendations on the best website or supplier for good quality lower cost cotton sheets and towels?

If it's a simple issue or something where we don't require a formal write-up, it could be $125-200.Then I'll bring in the specialists to get bids.If the problem is solved by putting up beams (bowing walls, typically), I'll bring in my foundation company who specializes in putting up beams and installing drain tile (the bowing issue is generally related to too much ground water pressing against the foundation, and the long term fix is to keep the water out).

We’ve noticed water seeping issues through the shower tiles, causing damage to the sheetrock in our only bathroom on main floor.

I would also replace the old sewer lateral out to the street, which is made from clay tile.

The home has wood floors, tile countertops, claw foot bathtub and a yard with an old-fashioned porch swing.
