Frequently Asked Questions
Which service fits your situation
How do I know if my windows need to be replaced?
A repair job — hardware, balances, screens or perimeter sealing — is sometimes all a sound frame needs. We fit replacement windows rather than carrying out repairs, but we will tell you honestly if that is all yours need.
What’s the average cost to replace windows in Dallas?
Replacement — the right call once a seal has failed, because no repair restores the gas fill between the panes. Window replacement →
How long does a window replacement project take?
Installation — new openings, additions, or a whole-home upgrade rather than a like-for-like swap. Window installation →
Can you install custom-sized or uniquely shaped windows?
Not sure? Book a free measurement and we will tell you which one you actually need — including if the answer is that your windows can wait a few years.
Is your work covered by a warranty?
Choosing a style — double-hung, casement, sliding, awning, picture, bay and bow all suit different rooms. Compare window styles →
