Velux & Skylights in South London

Velux Installation — What the Job Involves

We cut the opening between rafters (or modify rafter positions with structural trimming for larger windows), form the internal lining from plasterboard, install the Velux window with the manufacturer-specific flashing kit, and make good internally and externally. The flashing kit is critical — it is engineered to integrate with specific tile or slate profiles and creates a weathertight seal that a generic flashing cannot match. We are trained Velux installers and use the correct kit for every installation. This is why our Velux windows do not leak — and why many fitted by general builders do.

Choosing the Right Velux for Your Property

Velux offer centre-pivot (the standard opening), top-hung (opens outward from the top for better views), conservation-style (flush fitting for heritage properties), flat-roof versions, and fixed non-opening units for light only. Sizes range from 550×780mm to 1340×1400mm. Electric and solar-powered operation is available. We survey your roof pitch, rafter spacing, room size and building regulations to recommend the optimal window type, size and position for maximum light and ventilation while meeting planning requirements.

Common Velux Problems We Fix

Condensation between panes means the sealed unit has failed — replacement glass is available without replacing the whole window. Leaking is almost always a flashing problem, not a window problem — incorrect installation or degraded flashing kits cause 90% of Velux leaks we attend. Stiff mechanisms can usually be freed and re-lubricated. We carry common Velux parts and can repair most issues on the first visit. Full window replacement is only necessary when the frame itself is damaged or the window is more than 25 years old and multiple components have failed.

South London's Housing Stock and Velux & Skylights

South London's housing diversity means velux & skylights is never one-size-fits-all. Victorian terraces in Brixton and Peckham have different roof types and failure patterns than 1930s semis in Bromley and Croydon. Georgian townhouses in Camberwell and Blackheath require heritage-grade materials that conservation areas mandate. Post-war estates in Thamesmead and New Addington present entirely different challenges again. We have worked on every property type across every South London borough and specify materials and methods appropriate to each.

This depth of local knowledge means we diagnose faster, specify correctly first time, and deliver repairs that last. A national company sending a subcontractor who has never worked in South London cannot match that. We live here, we work here, and we understand what these roofs need.

South London Borough-by-Borough Coverage

We cover every borough south of the river. In Lambeth — Brixton, Clapham, Streatham — the dense Victorian terraces with their Welsh slate roofs and butterfly roof box gutters present specific challenges that require specialist knowledge. In Southwark — Peckham, Camberwell, Dulwich — the mix ranges from workers' cottages to grand Georgian townhouses on Camberwell Grove, with conservation area restrictions in Dulwich mandating natural materials. In Lewisham — Brockley, Catford, Forest Hill — Victorian and Edwardian stock dominates, with the Ravensbourne valley creating humidity conditions that accelerate slate nail sickness. In Greenwich — Blackheath, Woolwich, Eltham — Georgian heritage properties sit alongside the largest concentration of 1930s semis in South London. In Bromley — Beckenham, Petts Wood, Chislehurst — substantial 1930s and Edwardian houses with complex roof forms and heavy tree coverage require regular maintenance. In Croydon — Thornton Heath, Purley, Selsdon — the sprawling 1930s suburban stock faces particular challenges with hip tile mortar failure across thousands of hipped roofs. In Wandsworth — Battersea, Putney, Tooting — Thames-side humidity accelerates metal corrosion on the riverside properties while the Edwardian stock further south has its own distinctive repair demands.
