Velux window installation, replacement and leak repairs. Serving Lewisham (SE13, SE6, SE4, SE8) and surrounding areas with free quotes and a 10-year guarantee.
Victorian terraces throughout — particularly dense in Brockley, Catford and along Lewisham High Street. Edwardian properties in Honor Oak Park and Forest Hill. Major post-war estates including the Pepys Estate. 1930s semis in Hither Green and Downham. Modern developments around Lewisham Gateway.
For velux & skylights specifically, this housing mix creates distinct demands. Welsh slate on Victorian stock, clay tiles on Edwardian, concrete tiles on 1930s and post-war estates, flat bituminous roofs on post-war blocks. One of South London's heaviest slate-roofed boroughs. — and each roof type requires different materials, methods and experience to repair or replace correctly.
The Ravensbourne river valley from Bromley through Catford to Deptford Creek creates a humidity corridor. Properties in the valley bottom around Ladywell and Catford Bridge experience notably damper conditions than higher ground at Brockley and Honor Oak. For velux & skylights work, this means materials and methods must be specified for Lewisham's particular conditions — not generic South London assumptions.
Slate nail sickness across Brockley and Catford Victorian stock is the dominant repair call — original iron nails now 120–140 years old failing across entire streets. Box gutter failures on butterfly-roofed terraces in Deptford and New Cross cause concealed leaks. Flat roofs on rear extensions are a constant repair source.
Every velux & skylights job in Lewisham starts with a proper inspection — from the roof, not the pavement. We photograph the issue, explain the cause, and give you a written quote with no hidden costs. Most minor work is completed same-day. Larger projects are scheduled within days and we keep you updated throughout.
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.
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.
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.

The Ravensbourne river valley from Bromley through Catford to Deptford Creek creates a humidity corridor. Properties in the valley bottom around Ladywell and Catford Bridge experience notably damper conditions than higher ground at Brockley and Honor Oak. These conditions directly affect how we specify materials and methods for velux & skylights work. A repair that holds in sheltered Camberwell may not survive the same winter on an exposed Lewisham roof without the correct specification for local conditions.
