Guide ranges. The first visit is charged and priced before booking; any new glass is priced in writing before work starts. Scaffold, access towers or a crane are priced separately if the job needs them, and building control fees, where a job needs them, are shown as their own line.
Covering SE21 and neighbouring districts
Distance is rarely the deciding factor. A roof in Brixton, 2 miles from Dulwich, gets the same survey, the same written quote and the same fitting process as one in SE21, SE24 and SE22. What changes the price is the job itself: size of unit, roof type, access and lifting. Camberwell, around 2 miles out, is treated the same way.
What we do on the day
- Measuring visit to size the glass and identify its make-up
- New unit set on packers, then beaded, capped or bonded as designed
- Frame rebate cleaned and checked for damage, corrosion or failed seals
- Matching the glass make-up — We identify the existing glass so the replacement performs at least as well.
- Can the glass come out? — We check whether your rooflight has removable glass or a bonded unit before booking a fitting visit.
How the glass is replaced
The second visit is the quick one. With the new unit made to size, the fitters take the old glass out, check the frame and drainage paths, and set the new glass on packers so it sits square and drains properly. Seals and cappings are renewed where needed, the area is cleared, and you are shown what was done.
Do you need permission in Dulwich?
Two sets of rules matter in England. Planning: a rooflight on a house is normally permitted development if it projects no more than 0.15 m and stays below the highest part of the roof, but flats, listed buildings and Article 4 areas need checking. Building regulations: new openings need approval for the structure and energy performance, and a replacement is a controlled fitting. We are not registered with a competent person scheme, so we notify replacements to building control with a building notice and put the council's fee on the quote.
What to send us
Photos of the problem glass from inside and out, a rough width and length, and whether the rooflight opens or is fixed are enough to price the first visit. Add the postcode and how the roof is reached, and tell us if more than one unit has misted.
Common questions in Dulwich
Can you replace just the glass in my rooflight?
Often, yes. If the frame, gaskets and drainage are sound, a new sealed unit can go into the existing frame. If the frame has failed, is distorted or leaks around the edge, replacing the whole rooflight is usually the better answer, and we tell you that.
Can I upgrade the glass while it is being replaced?
Usually. Solar-control, self-cleaning, toughened or laminated glass can be specified as long as the frame can take the thickness and weight. We check that on the measuring visit and price the options side by side.
Is the measuring visit charged?
Yes. The first visit measures the existing glass and checks the frame, and it is charged. We confirm that price before you book. The fitting of the new glass is then priced in writing, so you see the full cost before anything is ordered.
