Inspect the door for any signs of damage, such as cracks, chips, or warping. Pay close attention to the corners and edges. Check the condition of the seals around the door and frame to ensure they are intact and provide a good weather seal. Test the locking mechanism to ensure it functions smoothly and securely. Also, check the glass for any cracks or damage.
Standard uPVC door sizes in the UK vary, but common widths are 762mm and 838mm, and heights are around 2032mm. To measure your existing door frame, measure the width and height of the opening from brick to brick. It's important to take several measurements at different points to account for any inconsistencies. Consider the threshold height as well. If replacing an existing door, measure the old door itself for reference, but always prioritise frame measurements.
Look for doors with a multi-point locking system, ideally with at least five locking points. Check that the cylinder lock is anti-snap, anti-drill, and anti-bump to prevent forced entry. Consider doors with reinforced panels and frames. Ensure the door meets PAS 24 security standards, which indicates it has been tested against common burglary methods.
When replacing a uPVC door, it must meet current building regulations regarding thermal performance (Part L) and, in some cases, fire safety (Part B). If you are replacing a door with a glazed unit, it must be safety glass. If you are altering the structural opening, you may also need planning permission. It's advisable to consult with a qualified installer who can ensure compliance with all relevant regulations. In some cases, you may need a FENSA certificate from the installer to prove compliance.
Look for doors with a high energy rating, indicated by a U-value. A lower U-value means better insulation. Ensure the door has a good weather seal to prevent drafts. Consider doors with double or triple glazing filled with argon gas for improved thermal performance. Check that the frame is properly insulated and that there are no gaps or cracks that could allow heat to escape.
