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.
Where our fitters travel
Distance is rarely the deciding factor. A roof in Watford, 4 miles from Rickmansworth, gets the same survey, the same written quote and the same fitting process as one in WD3, WD18 and WD1. What changes the price is the job itself: size of unit, roof type, access and lifting. Chalfont St Peter, around 4 miles out, is treated the same way.
Included in the work
- Commissioning and sign-off carried out by the specialist before handover
- New vent fitted, sealed and weathered into the roof
- Existing vent, actuator and upstand surveyed with the specialist
- Upstand and weathering — We check the upstand suits the new vent and that the roof around it is sound.
- Free area at the stair head — We check the free area the vent must provide before choosing a replacement.
A typical installation day
On the day, you need to be in at the start and at the end. In between, the fitters get on with it. They will want the room below cleared where possible, a parking spot if you have one, and somewhere to set the unit down safely. After checking the opening and the upstand or flashing, they fix a smoke vent rooflight, seal it and finish the inside. Packaging and any old unit leave with them unless the quote says otherwise.
Regulations for Rickmansworth 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.
What to send for a quick quote
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 WD3 and we will come back with a quote or a survey date.
Common questions in Rickmansworth
Do commercial rooflights need planning permission?
Like-for-like replacements on commercial buildings rarely need planning permission. New or larger rooflights on non-domestic buildings and blocks of flats usually need checking with the planning authority, because householder permitted development rights don't apply. We tell you what we know about your building and point you to the right team.
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 upstand height and roof pitch does smoke vent rooflight fitting need?
It depends on the product. Manufacturers usually specify a minimum upstand height above the finished roof surface, and a minimum pitch on the glass so rain runs off. We follow the maker's figures for your unit rather than a rule of thumb. If your existing kerb or roof falls short, we explain the options, such as raising the upstand or choosing a unit with built-in pitch.
