📞 Call Now: 0172 223 9611Velux window installation and flashing repair across Harnham and surrounding SP2 villages. New roof light installation, EDW and BDX flashing replacement, leaking Velux diagnosis — and planning advice for properties in Harnham's conservation areas or with permitted development restrictions.
The standard EDW flashing kit has a service life of 10–15 years in average UK conditions. Given chalk escarpment, south-westerly exposure on upper ground and upper escarpment: accelerated ridge mortar; lower streets: water meadow humidity, properties in Harnham on exposed elevations or south-west-facing slopes — especially given lime mortar on Victorian terraces; lead valleys on Old Harnham Road properties — experience shorter EDW service life. We recommend the upgraded BDX or BFX flashing kit on all exposed positions in the SP2 area for extended service life.
Most Velux installations fall within permitted development for Harnham properties and do not require planning permission, subject to standard conditions (not projecting more than 150mm, not on principal highway-facing elevation). Properties within Harnham's conservation areas or listed buildings have additional restrictions — we check the planning position for your specific property before any installation is confirmed.

📞 0172 223 9611Rooflights leak at the flashing kit, not usually the glass — so a leaking Velux is often a fitting or flashing problem rather than a faulty window.
When it is not the answer: A leaking rooflight often needs only a new flashing kit, not a whole new window — we'll check before quoting a replacement. Read the full guide.
We check the window, the flashing kit and the surrounding tiles or slates.
Itemised quote for a new flashing kit, a like-for-like swap, or a new install.
Usually a single day per rooflight.
We fit the window and manufacturer flashing kit, integrating it with the covering and underlay so it's fully weathertight.
Internal reveal made good if agreed, site cleared, guarantee handed over.
| Job | Typical duration |
|---|---|
| New flashing kit only | Half a day |
| Like-for-like replacement | 1 day |
| New rooflight install | 1–2 days |
| Multiple rooflights | 2–3 days |
We keep the opening covered and weathertight at all times; heavy rain can pause a mid-swap.
Rooflight work runs from scaffold or a tower for safe access to the slope. Scaffold is specified for: new installs, multiple units, or steep slopes - always itemised in your written quote, never a hidden extra, and we arrange it.
A mix of Victorian villas and inter-war and post-war housing close to the Cathedral view; some period stock. Pavement scaffold and skip permits go through Wiltshire Council; allow a few working days on streets like the older lanes off Harnham Road near the watermeadows where space is tight.

If a fault appears in covered work, we come back and put it right. No quibbling, no re-charge.
Some internal access needed and a little plaster make-good on new installs; external work is quick and tidy. You do not need to stay home for external work - we just need power and access agreed in advance.
