Smoke vent rooflight installation in Harlow

A rooflight is not finished when the roof is watertight. The inside matters too: the reveal or lining around the opening, the plaster, the trim where it meets the ceiling. Some installers leave that for somebody else. When we quote for smoke vent rooflight installation in Harlow, internal finishing is listed so you can see whether it is included or left for your decorator. That way a smoke vent rooflight looks right from the room below as well as from outside. We cover Harlow and properties throughout Essex.

Guide ranges for supply & fit; controls and commissioning by a smoke-control specialist. Your price is fixed in a written quote after we have seen photos or surveyed. 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.

Fitting across Harlow and nearby

Jobs across CM20, CM18 and CM17 are part of our normal cover for Harlow. We are not an office on the high street. Our fitting teams come out to the property from wherever they are working that week. Neighbouring places such as Hoddesdon and Ware are covered on the same terms, so a house on the edge of town is no harder to book than one in the centre.

What we do on the day

  • New vent fitted, sealed and weathered into the roof
  • Controls, detection and wiring handled by the smoke-control specialist
  • Old vent removed with the stairwell kept protected below
  • Fire rules near escape routes — We check the roof around the vent for fire rules that affect it.
  • Certified as a system — We only fit smoke vents that are certified to BS EN 12101-2.

How a fitting day runs

Protection comes before tools. Floors, furniture and stairs get covered, and the ceiling below the opening is sheeted to catch dust. Up top, the fitters confirm the opening is square and the upstand or flashing suits what the maker specifies. Fixing follows, then weather-sealing into the membrane, felt or tiles. Only once the roof is tight do they turn to the internal reveal. Time on site for a smoke vent rooflight: one to two days per vent, weather permitting.

Regulations for Harlow properties

A replacement smoke vent in England has to keep the free area and performance the building's fire strategy relies on, using a vent certified to BS EN 12101-2 with its actuator and backup power. We fit the vent and do the roof work; a smoke-control specialist connects and commissions the controls, and we confirm whether building control needs to be notified.

Getting a price from photos

What we cannot see, we have to guess, and guesses make quotes wider. So the more you send, the tighter the price. Useful: shots from the roof or garden, shots from the room underneath, a rough width and length, the roof finish, any access problems, and the product page if you have already ordered. Add the property postcode around CM20 and we will come back with a quote or a survey date.

Common questions in Harlow

Can you remove and dispose of the old rooflight?

Yes. Taking out the old unit is part of any replacement job, and it leaves with the rest of the waste unless you ask to keep it. Old domes, glass and frames go through proper waste routes. If removal turns up a rotten kerb or damaged decking, we show you what we have found and agree the repair with you before going any further.

What if my roof opening is the wrong size for the smoke vent rooflight?

We find out before the fitting day, not on it. If the opening is slightly out, it can usually be adjusted by trimming or by packing out the upstand. If it is a long way off, the choice is between altering the opening and changing the unit. Bear in mind that rooflights are often sold by builder's opening size rather than external size, so check which one your measurement refers to.

Do you need scaffolding to fit a rooflight?

Not always. Single-storey roofs can often be reached safely with ladders, a tower or edge protection. Higher roofs, steep pitches and large units usually need scaffold or a mobile platform, and heavy glass may need a crane. We assess access from your photos or at the survey, and any scaffold or lifting cost is shown as its own line on the written quote.
