What to check before you hire
Worth checking yourself
Always confirm credentials and quotes with the business directly before hiring.
Be wary of high-pressure 'today-only' discounts and a salesperson who won't leave. A reputable window or door firm gives you a written, itemised quote you can take away and compare against others.
Never pay the full price up front; a modest deposit with the balance on completion is normal. Ask what deposit protection or insurance-backed guarantee you get if the firm stops trading before fitting.
Get the specification in writing (frame material, the glazing units and their energy rating, and any trickle vents) so you can check you got what you paid for.
