Fire stopping across Leeds

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Maintenance after handover

Cleaning and maintenance staff play a part too. Share these points with them:

  • Include service cupboards in routine inspections
  • Get seals inspected before ceilings and boxing close
  • Leave fire sealant to cure fully before covering it
  • Treat an open penetration as a priority repair

After every round of M&E works, check that the openings created have been sealed. Building it into each contractor’s sign-off keeps the walls intact.

A simple record of seal locations and products helps. It tells the next contractor exactly what to reinstate.

How we handle fire stopping in Leeds

On a fit-out or refurbishment, we follow the services contractors floor by floor. To price a package, speak to us on 01277 525 020 or send details through our quote form with the schedule or marked-up drawings. Tell us what records you need and we’ll confirm with the quote. We work on service gaps in risers, linear gaps at wall heads and cable penetrations, and the failures we’re asked to look at most are penetration schedules that need working through and open linear gaps along the top of fire-resisting walls. Most enquiries from Leeds start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.

Smaller places such as Leeds still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.

Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

What affects the price in Leeds

Your fixed quote is built from the real scope. It allows for:

  • Induction, permit and paperwork requirements
  • Joint width, depth and condition
  • Distance, for remote addresses
  • Quantities, in metres or numbers

The specified product makes a difference, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site rules also count.

Details that help us quote

Diagnosis starts before we arrive. Tell us:

  • The type of building and who uses it
  • When you need the work done
  • Specification clauses that apply
  • Clear photographs of the problem areas

Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to call 01277 525 020 or send photos by email with what you know.

Surface by surface

Risers and ceiling voids

Voids hide a lot of unsealed openings. We work through the areas on your schedule methodically, and note anything we find that isn’t on it.

Drylining partitions

Holes in board are often cut larger than needed. An oversized hole may be outside the sealant’s range.

Common questions from Leeds clients

Is Park Wood Trading Estate, near Leeds, within your area?

Yes. We cover Leeds and the area around it, including industrial estates, business parks and retail parks such as Park Wood Trading Estate. Photos and a short description are enough for a first look.

What does the BS 476 change mean for fire-rated sealant in Leeds?

Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.

Can the sealant be colour-matched?

In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.

Do you work in Leeds?

Yes. Sites across Leeds are covered.

Can you fit around our working hours?

Give us your site hours and any access windows in your enquiry, and we will plan around them. You can reach the office between 8am and 5pm, Monday to Friday.

Do you take on small jobs?

Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.

Can the building stay open while you work?

Yes, as long as we plan it. Tell us your site hours and access windows and we’ll plan around them.

How a job runs

On arrival, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before anything is cut or cleaned, and the work normally takes a single visit for a short list of penetrations, or a phased programme for a whole building. Jobs in and around smaller places like Leeds are normally planned as a single visit, so photos and measurements up front really help. Then the right materials arrive with us.

  1. The specification and schedule come first, so we know which details apply.
  2. Access, permits and the order of areas are agreed with the site team.
  3. Each opening is checked for wall or floor type, service, gap and depth.
  4. Foam, ordinary sealant and debris come out.
  5. The specified backing and sealant go in to depth and are finished neatly.
  6. We tell you about openings that need a different product.

What we need from you

  • Let us know about inductions and permits
  • Let building users know which areas are affected
  • Share the asbestos register for older buildings

Advice

Why it’s worth doing now in Leeds

Sealing behind the M&E trades area by area beats a sweep at the end. While the area is still open, every opening is easy to see and reach, and the right detail can be checked at the time. For buildings around smaller places like Leeds, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote and we’ll explain how it’s made up.

Why appoint us

  • Our applicators hold CSCS cards
  • Products installed to the manufacturer’s instructions
  • Clear, fixed quotes
  • One number for every site we cover

Do you need fire stopping in Leeds?

Some seals fail because the wrong product went in: expanding foam or a general-purpose sealant pushed into a gap to tidy it. It may look closed, but it has no tested fire performance in that position, so it has to come out.

Site and facilities staff are often the first to spot these:

  • Fire-stopping items raised at inspection or handover
  • Openings left by services added after handover
  • Fire seals cut back for extra cables and never reinstated
  • Head-of-wall gaps with no fire seal

Residences at universities like Canterbury Christ Church University (to the north-east of Leeds) have compartment walls that must be resealed whenever services change.

Comparing quotes

  • Whether primer will be used where the manufacturer specifies it
  • What site paperwork they can supply
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Is the sealant right for the movement and the substrate?

How to choose a sealant contractor

Where services cross fire walls in Leeds

Approved Document B is the English guidance that covers fire stopping around openings and penetrations. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. What we install is set by the specification, and it goes in to the tested detail. Several hotels sit less than 2 miles from Leeds. In hotels, bedroom and corridor walls are usually fire-resisting, so services added in a refit need sealing with the specified product.

Colleges such as Kent Police College (to the west of Leeds) add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product. Where a unit on an estate such as Park Wood Trading Estate (1.9 miles west of Leeds), has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail.

Leeds is about 4 miles east of Maidstone, in Kent. Commercial clients in Leeds use us for work on service penetrations. Leeds is one of 931 places in Kent on our list for service penetrations. Sites around London have their own page, about 35 miles away.

If you need fire stopping in ME17, the process matches everywhere else we work: send details, get a quote, we seal, guaranteed. Among the streets we cover are Brogden Crescent, Forge Lane and Gloriette Avenue. Close to Leeds, our area also takes in Ashbank (1 mile north-east), Broomfield (1 mile east), Eyhorne Street (1 mile north-east), Chartway Street (2 miles south) and Kingswood (2 miles south-east). A short drive away, we cover Maidstone (4 miles west), Ashford (13 miles south-east), Sittingbourne (9 miles north-east), Tonbridge (15 miles west), Faversham (13 miles east) and Minster (15 miles north-east).
