uPVC flush sash windows for Harrow jobs

A flush sash window is usually chosen for how it looks, so the details matter: hinge type, handle style, glazing bars and the woodgrain finish are all listed separately on your quote so nothing is left to assumption.

Many period houses are in conservation areas or are listed. Planning rules for windows are set by the local council, so check with the planning department before ordering for those properties.

• Trickle vents concealed in the frame where specified
• Matching run-through sashes for a balanced sightline
• Double glazed as standard, triple glazing available

Measuring tip

Flush sash frames are deeper than standard casements, so check the reveal depth and any existing timber sub-frame before you finalise sizes, and note it on your schedule.

Regulations for jobs in Harrow

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.
