uPVC casement windows for Dorchester jobs
If the property needs background ventilation, tell us which windows take trickle vents and we fit them in the frame head before dispatch, which saves routing them on site.
Casements cover most replacement work in the UK because almost any opening can be laid out with a mix of side-hung, top-hung and fixed lights. You give us the sizes and opener layout and each window is made to that schedule rather than chosen from a list of standard sizes.
- Multi-chambered uPVC frame and sash profile
- Friction stays with easy-clean option on side-hung sashes
- 28mm double glazed sealed units as standard, with argon and a low-E inner pane
- Warm-edge spacer bar available on request
Delivery to Dorchester
We deliver to sites and yards in Dorchester as part of our mainland delivery service. Delivery is priced on the quote, so you know the full cost before you place the order. Postcode districts include DT1.
Getting a price
List every item on one schedule with sizes in millimetres, width first. Add the finish and options per line and we price each one.
Open a trade account to order at trade prices. We ask for your business details and how you expect to order, and agree terms when the account is set up.
Measuring tip
Measure the brick opening at three points across and three points high, take the smallest of each, then deduct your fitting gap (usually 10mm overall each way) to give the frame size you order.
Regulations for jobs in Dorchester
Replacement windows in England should meet Approved Document L: a U-value of 1.4 W/m²K or a Window Energy Rating of band B. Approved Document F expects background ventilation to be no worse than before, which usually means trickle vents. Glazing in critical locations must break safely, be robust or in small panes, or be permanently protected under Approved Document K, which in practice usually means toughened or laminated safety glass. Rooms that need an escape route may need an escape window under Approved Document B. Replacing windows is notifiable building work: the installer self-certifies through a competent person scheme such as FENSA or Certass, or the work goes through building control.

Trade pricing is for business customers with an account. You can apply online and request a quote at the same time.
Do you deliver uPVC casement windows to Dorchester?
Yes. We deliver to sites and yards in Dorchester, and the delivery charge is shown on your quote before you order.
Do the windows meet building regulations?
They can be specified to meet the thermal values in the building regulations for where the job is, with trickle vents, safety glass and escape hinges added where the regulations call for them. Your installer is responsible for any notification or approval the job needs: in England and Wales usually through a competent person scheme; in Northern Ireland through council building control; in Scotland, replacement windows in a house do not normally need a warrant but must meet the standards.
