With summer afternoons well into the triple digits, glazing is a cooling-cost decision as much as an appearance one. A great many valley homes still carry the builder-grade aluminium or early dual-pane windows they were built with.

Hiring windows & doors in Temecula — what to know

Will new windows actually cut my cooling bill?

In this climate they can make a real difference, particularly on west-facing glass taking the full afternoon sun. Low-E coatings are aimed squarely at exactly this problem.

What is the fogging between my panes?

A failed seal in a dual-pane unit. The glass unit can usually be replaced without replacing the whole window frame.

What licence covers window replacement?

A C-17 glazing licence. Some window work is also done under a B general building licence.
