What do dome rooflights in East Grinstead involve?
Dome rooflights in East Grinstead means polycarbonate and acrylic domes for flat roofs, new or replacement. We cover the RH19 district and the rest of West Sussex, with a survey before any price is fixed.
Larger gardens in much of the South East mean deeper rear extensions, and deeper rooms need light from above rather than only from the doors. Dome rooflights suit schools, flats and commercial flat roofs.
East Grinstead is around 12 km from Crawley, and we survey and fit throughout that part of West Sussex, including the RH19 district.

Common questions
Do domes leak?
Leaks are usually at the upstand seal or the membrane. Replacing the dome and resealing often fixes it.
Why has my dome gone yellow?
UV breaks down older plastics over time. Modern domes have UV-protective layers, but all plastics age.
Are domes safe to walk on?
No. Treat any rooflight as fragile unless it is specifically certified non-fragile, and never stand on it.
