📞 Call Now: 0172 223 9611Velux window installation and flashing repair across Andover and surrounding SP10 villages. New roof light installation, EDW and BDX flashing replacement, leaking Velux diagnosis — and planning advice for properties in Andover'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 exposed Hampshire Downs at 80m and open chalk plain, direct south-westerly and northerly exposure, properties in Andover on exposed elevations or south-west-facing slopes — especially given nail sickness widespread across New Town estate concrete tile stock — experience shorter EDW service life. We recommend the upgraded BDX or BFX flashing kit on all exposed positions in the SP10 area for extended service life.
Most Velux installations fall within permitted development for Andover properties and do not require planning permission, subject to standard conditions (not projecting more than 150mm, not on principal highway-facing elevation). Properties within Andover'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.
Victorian terraces near the old town with very large post-war and modern estates around them; extensive concrete-tile stock. Pavement scaffold and skip permits go through Test Valley Borough Council; allow a few working days on streets like the older streets around the centre where space is tight.

No deposit on repairs under £500; staged payments on larger jobs with nothing up front before materials are on site. Repairs are standard-rated; a full re-roof usually attracts 5% VAT.
Covering SP10, SP11 and surrounding postcodes.
Velux and other branded units carry manufacturer warranties; our fitting is guaranteed for up to 10 years.
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.
We plan installs around dry windows and never leave an opening exposed. Test valley town on the chalk; exposed edges catch the wind.
