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 Gravesend we cover
Gravesend and the districts around it, DA11, DA12 and DA10, all sit inside our working area. So does the ground between Gravesend and Swanscombe (3 miles), and on towards Grays (3 miles). When a fitting team is booked, their travel is already in the quoted price, so it does not turn up as a surprise line on the final bill.
On the day, we cover
- Existing vent, actuator and upstand surveyed with the specialist
- Controls, detection and wiring handled by the smoke-control specialist
- Upstand checked, adapted or rebuilt to the vent maker's drawing
- Free area at the stair head — We check the free area the vent must provide before choosing a replacement.
- Certified as a system — We only fit smoke vents that are certified to BS EN 12101-2.
From arrival to clean-up
Fitting days start with a look at the sky. If rain is due, the order of work changes so the roof is never left open to it. A typical day for a smoke vent rooflight runs like this: set up access, protect the room, open up the roof or prepare the existing kerb or frame, check sizes, fix, seal, then finish inside. On jobs that take more than a day, the opening is weather-sealed overnight. The last hour goes on tidying, waste removal and a walk-round with you.
Do you need permission in Gravesend?
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.
Before you get in touch
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 DA11 and we will come back with a quote or a survey date.
Common questions in Gravesend
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.
How does payment work?
Payment terms are set out on your written quote before you accept it. Depending on the job, that may mean a deposit, stage payments for larger work, or payment on completion. The contract is with S&K Property Investments and Improvement Ltd, part of the S&K Group. Nothing is added without your agreement: if something unexpected comes up, we discuss it and agree any change before carrying on.
Do you cover Gravesend?
Yes. Fitters travel to addresses in Gravesend and the surrounding districts, including DA11. 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.
Tell us your postcode, DA11 or close by, and what you want fitted. We will reply with the next steps and a quote.
