Tell us the job in 30 seconds. No pushy sales, no call-out fee.
Single-storey rear extensions are widespread across Totton's 1960s and 1970s housing stock — and many of these extensions have felt flat roofs now being replaced with GRP. A skylight integrated into a new GRP flat roof is the ideal time to install — it is included in the flat roof programme rather than requiring a separate return visit. We routinely include skylights in flat roof replacement quotes for Totton extension properties.

Request Free QuoteVelux window installation in Totton requires the correct approved flashing kit for the roof covering in place. The concrete interlocking on Calmore estates, clay tile and slate near the older town centre across Totton's housing stock requires different flashing geometry for each product type. On concrete interlocking tile — the most common type in Totton's estate housing — the flashing profile must match the tile profile precisely. An incorrectly specified flashing on any tile type will leak in its first wet winter. We use manufacturer-approved kits for all tile types.
Most single Velux installations in Totton are permitted development — no planning permission required. Restrictions apply to front or principal elevation windows in conservation areas, windows projecting more than 150mm above the roof pitch, and any work on listed buildings. We advise on planning implications at the survey stage for all Totton and SO40 properties before providing a quote.
Single-storey rear extensions in Totton can be significantly improved by integrating a fixed-light or opening skylight into the flat roof. If your flat roof is being replaced at the same time, including a skylight in the programme is the most cost-effective approach — no separate return visit and the skylight can be seamlessly integrated into the new GRP or EPDM system. We quote for combined flat roof replacement and skylight installation across Totton and all SO40.

A roof window transforms a dark Totton loft or extension, but it must be installed and flashed correctly or it becomes a leak. Here is what to know.

Roof-window installation needs scaffold or towers for safe external access and flashing, itemised in the quote. Scaffold is specified for: all pitched-roof window installations above single-storey - always itemised in your written quote, never a hidden extra, and we arrange it.
Totton and Calmore have large post-war estates where scaffold access is straightforward but permits run through New Forest District Council. Pavement scaffold and skip permits go through New Forest District Council; allow a few working days on streets like Commercial Road, Rumbridge Street, the older streets near the Test where space is tight.

One or two days with some cutting noise and internal making-good; we sheet the room below and clear up fully. You do not need to stay home for external work - we just need power and access agreed in advance.
