Double Glazing FAQs
How long does double glazing last?
A well-fitted uPVC or aluminium window typically lasts 20 to 35 years. A sealed glass unit can mist sooner if its seal fails, but that’s a straightforward glass-unit swap, not a full window replacement.
What are the benefits of double glazing?
Better thermal insulation, reduced outside noise, stronger multi-point locking, and less condensation than single glazing.
Do I need planning permission to replace my windows?
Most standard residential replacements fall under permitted development rights. Conservation areas and listed buildings can be exceptions — we’ll advise on your survey.
How long does window installation take?
A typical installation takes one to two days for an average-sized home, depending on the number of windows and the specification.
Do you work on commercial properties?
Yes — we work with domestic homeowners and commercial customers throughout Southampton and Hampshire.
