Frameless structural rooflights in Mitcham: what is involved?
Thinking about frameless structural rooflights in Mitcham? The short answer: minimal glass rooflights with no visible frame from inside. The longer answer depends on your roof, which is why we survey before we price.
Mansard and loft conversions are common across London, and roof windows are often set out alongside dormers on the rear slope. In Mitcham, as anywhere, frameless structural rooflights are the usual choice for rooms where you want sky without a visible frame.
From Mitcham to Morden, Wimbledon and Streatham, the same survey-first process applies: measure, specify, fix the price, then fit.

Planning, building control and Mitcham
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line. A rooflight on a side-facing slope must be obscure-glazed, and fixed shut unless the opening part is more than 1.7 m above the floor.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.

Frameless structural rooflights in Mitcham: questions
How is it lifted onto the roof?
Larger panes go up with a vacuum lifter, a hoist or a crane. We plan access at survey.
Will I see the edge of the glass?
From inside, the reveal is finished up to the glass so the edge is hidden. From outside you will see the glass and its edge seal.
Can it open?
Some frameless designs include a sliding or hinged opening element, but most are fixed. Pair with an opening unit if you need ventilation.
How do I book a survey in Mitcham?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Do I need to be at home for the survey in Mitcham?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
