Here are some questions homeowners ask before replacing their windows or doors
Prices vary depending on window size, style and glazing type, but most homeowners can expect a straightforward, no-obligation fixed quote within 24 hours of a free survey.
Front door pricing depends on the material (composite, uPVC, aluminium or timber) and any added security or glazing features — we'll confirm an exact price after a quick assessment.
No — we operate a no-deposit policy, and you're never asked to pay until you're 100% satisfied with the completed installation.
Yes — modern uPVC and aluminium windows offer significantly better thermal insulation than older single or double glazing, helping to reduce heat loss.
Energy-efficient windows reduce heat loss through your walls and glazing, which can lower your heating costs over time, especially when paired with A-rated glass.
