Smoke vent rooflight installation in Great Sankey

Plenty of rooflight trouble starts with a tape measure. Units are often sold by the builder's opening, meaning the hole in the roof, rather than the overall external size, and confusing the two leaves you with a frame that does not suit the opening. Before we fit any smoke vent rooflight in Great Sankey, we measure the opening, the upstand or kerb where there is one, and the finished roof level, then compare them with the maker's drawing. If something is out, you hear about it before the fitting day rather than on it. That single check keeps most jobs like this on track.

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.

Coverage in and around Great Sankey

Jobs across WA5, WA2 and WA1 are part of our normal cover for Great Sankey. 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 Warrington and Newton-le-Willows are covered on the same terms, so a house on the edge of town is no harder to book than one in the centre.

Included in the work

  • Existing vent, actuator and upstand surveyed with the specialist
  • Upstand checked, adapted or rebuilt to the vent maker's drawing
  • Commissioning and sign-off carried out by the specialist before handover
  • Controls and backup power — We confirm the controls, detection and backup power are being dealt with by a specialist.
  • Certified as a system — We only fit smoke vents that are certified to BS EN 12101-2.

What happens on the day

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.

Planning, building control and Great Sankey

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.

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 WA5 and we will come back with a quote or a survey date.

Common questions in Great Sankey

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.

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.

What is included in the price?

The written quote lists it line by line. Typically that covers fitting labour, fixings, sealants, membrane or flashing materials, any upstand work, internal finishing if agreed, and taking away the waste. For supply and fit, the unit itself is included too. Scaffold, lifting gear and any third-party fees, where needed, are shown separately so you can see what each part of the job costs.
