I was thinking of the savings, and considering a professional company might charge $100-$200 per window installation, I saved quite a bit! Look at the pricing below (estimation):
Silicon Caulk: $3
Use pre-constructed window: $48
DIY using individual blocks: $30
Mortar mix (80 lb): $7
Of course you have to spend the time doing it, but if you're strapped for money, isn't doing it yourself the obvious choice?? A couple things I have discovered in doing this...
- Measure, measure, measure so you get the right size blocks!
- Always allot ample time to prep the sill the window is being placed on; sometimes the sill needs to be repoured.
