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.
Areas around Pinner we cover
Covering Pinner means covering the people who live and work there, not a single postcode. We take on domestic and commercial jobs in HA5, HA2 and HA6, and are happy to quote further out in Wealdstone and Ruislip. If your address sits between towns, tell us and we will confirm whether it falls in our normal area or needs travel set out separately on the quote.
Included in the work
- Old vent removed with the stairwell kept protected below
- Upstand checked, adapted or rebuilt to the vent maker's drawing
- Certified vent and actuator matched to the opening and controls
- Free area at the stair head — We check the free area the vent must provide before choosing a replacement.
- Upstand and weathering — We check the upstand suits the new vent and that the roof around it is sound.
How a fitting day runs
Arrive and agree the plan. Sheet the floor and furniture. Set up the ladder, tower or scaffold. Check the opening, the upstand or flashing, and the unit against the paperwork. Fix and pack a smoke vent rooflight level. Seal it into the roof. Line the reveal or fit the ceiling trim. Clean the glass, clear the waste, and talk you through it. That is the shape of most fitting days, and for this type of job it usually takes one to two days per vent.
Planning, building control and Pinner
In England, smoke vents for common stairs must be certified to BS EN 12101-2, provide the free area the fire strategy requires (Approved Document B calls for at least 1 m² at the top of a common stair), and have backup power. Smoke vents have their own energy limit, commonly 3.5 W/m²K. Controls and commissioning are handled by a smoke-control specialist, and building control is involved where the system changes.
What to send for a quick quote
Each detail you send takes a question off our list. Photos inside and out show the opening and the ceiling. Rough measurements tell us the unit size. The roof covering tells us how it will be sealed in. Access notes tell us whether a tower or scaffold is needed. A product link, if you have one, lets us check it against the opening. Your postcode, HA5 or nearby, confirms travel.
Common questions in Pinner
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.
Does commercial rooflight work need building control?
Usually. New openings, structural changes and smoke vents go through building control, and on buildings covered by fire safety law that means a full plans application rather than a building notice. We are not registered with a competent person scheme, so replacements we fit are notified to building control. We confirm the route and show any fee on the quote.
Do you cover Pinner?
Yes. Fitters travel to addresses in Pinner and the surrounding districts, including HA5. We do not run an office there; the survey and the fitting happen at your property. A few island and remote postcodes are covered by arrangement; if yours is one, we confirm travel and dates before quoting.
Send a few photos and your HA5 postcode, and we will put together a written quote for the job.
