Choosing uPVC windows involves more than picking a frame colour. The system, opening style, glass and fitting work all form part of the proposal. Start with how you want each room to work, then compare the available options.

Choose an opening style for each room

Think about reach, cleaning access and the space around the window. Opening sections and fixed panes can be arranged differently according to the system. Ask for a drawing so you can see what moves and where the handles sit.

Compare the frame and finish

Look at a real sample of the proposed frame where possible. Check the appearance of the joints and the finish on both faces. Colour choices vary by system, so record the exact inside and outside finish in the specification.

Select the glass for its purpose

Tell us if privacy, heat loss or outside noise is a concern. Ask which glass is proposed and what information supports any performance claim. Compare information for the complete window as well as the glass.

Allow for regular care

uPVC windows still need cleaning and checks of their moving parts. Follow the instructions for the frame finish, seals, hinges and locks fitted to your windows. Ask for those documents with the order.

Compare the full price

Check the product, glass and finish alongside delivery, fitting, VAT and work around the opening. An initial estimate can be prepared from photos and approximate measurements. After you accept it, the final survey checks the details needed to confirm the order.

Questions

Is every uPVC window the same?

No. Frame systems, glazing, opening arrangements and fittings differ. Ask for the proposed product to be named on the quote.

Will new uPVC windows stop outside noise?

Ask what sound-reduction evidence applies to the proposed window. The result depends on its specification and installation, together with other sound paths in the building.

Can I choose different finishes inside and outside?

Ask which combinations are available for the selected system. Record the agreed choice in writing.

Send photos, rough inside measurements and your postcode for an initial estimate. Tell us which rooms and opening styles you are considering.
