Do you replace window seals for a small job?

Seals can sometimes be replaced, but if the sealed unit has failed, replacing the unit is usually needed. a window-specialist will assess the most effective option. Share the age of the property, access, and what you want to change so the Window Specialist can plan the right approach.

What is a sealed unit?

A sealed unit is the double glazed glass component that sits within the frame. If it fails, condensation can appear between panes. It can often be replaced without changing the frame. It helps to note any existing issues, recent work, and the areas involved.

Can you fit safety glass?

Yes, safety glass can be fitted where required or preferred, such as in doors or low level glazing. a window-specialist can advise on suitable options. Ask what is included, how long the work may take, and what happens if extra issues appear.

How do you measure for new windows?

a window-specialist will measure the openings to ensure a precise fit. If you are requesting a quote, approximate sizes and photos are still helpful for an initial estimate. Photos and measurements can help the Window Specialist give clearer guidance.

Will new windows match my existing ones for a small job?

Matching is usually possible, but exact matches depend on material and availability. Provide photos and details of the existing style so the Window Specialist can advise. If relevant, confirm how services will be isolated and when they will be restored.

Can you work on rooflights?

Some window-specialists handle rooflights. Share the type and access details so they can confirm whether it is within scope. Share the age of the property, access, and what you want to change so the Window Specialist can plan the right approach.
