Floor tile cost and windows cost question

[Joel Owens]

Looking at 12 X 12 tiles at 54 cents a apiece or 18 by 18 for 84 cents apiece.

The area we would be tiling on concrete is the main level.Another unit I own with exact space and layout is already tiled 12 by 12.The whole floor makes up 410 tiles.

We can buy pre-mixed mastic or do it ourselves.The mix yourself is cheaper but I think it is way messier and we might not get the mix just right. How many 18 by 18 tiles would I need versus 410 12 by 12 tiles??

Was thinking 18 by 18 would be cheaper and use less grout and not take as long to cover the area.The flooring place says you use a little thicker mastic and thinner grout lines.Never laid tile before but it seems easy.Anything else needed besides bucket,trowels,mastic,tile cutter,grout,and spacers,and a level?? Tiles of course.

Now windows for the outside are broken. Some are dual pane.First estimate company was high at 2,400 for 18 panes of glass.Next company seems good but I do not know what glass costs.

Estimate is exterior glass windows quantity 11 double panel 15 7/8 by 43 3/4 alum 1/4 and glass 1/16

Double Panel quantity 6 - 28 by 44 Alum 1/4 Glass 1/16

1,700 with labor all in and materials.

Exterior french door glass 20 by 64 all in for 125 parts and labor.
