Fire stopping in Maze Hill, done properly

A lot of fire-stopping work comes after M&E installation, a refit or a tenant fit-out. New cable runs, replaced pipework and extra data routes all punch holes in compartment walls, and they are easy to forget. We close the openings listed on your schedule, using the specified sealant and detail. If you’re dealing with fire-rated sealant that has cracked or shrunk back and penetration schedules that need working through, we can help. One point of contact handles commercial sealant work in Maze Hill from the first photographs to the final walk-round, whether it’s one building or several.

After a fit-out or new cabling in a London building, risers and ceiling voids are where open service gaps tend to be found. If sealant is the specified product we fit it to its tested detail, and if the detail needs something else, you will hear it from us.

The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Common questions from Maze Hill clients

Will you plan work around the academic year at somewhere like University of Greenwich?

Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Do you cover business parks and estates near Maze Hill, such as Angerstein Business Park?

Yes. We cover Maze Hill and the area around it, including industrial estates, business parks and retail parks such as Angerstein Business Park. To start, just phone 01277 525 020 or email the details over with the unit, the joints involved and your access times.

Do you take on multi-site work?

Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.

Can you seal any opening with fire-rated sealant?

No. It depends on the tested detail for that wall or floor and service. Collars, wraps, batts and boards exist for openings sealant doesn’t cover, and we’ll tell you when that applies.

What will the job cost?

Every job gets its own fixed quote. To get one, call the office on 01277 525 020 or email us with a description of the work.

How do you choose the sealant?

A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Is any job too small?

We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.

Fire stopping in Maze Hill: the local picture

The area within 2 miles of Maze Hill holds a good number of hotels. In hotels, bedroom and corridor walls are usually fire-resisting, so services added in a refit need sealing with the specified product. In London buildings, frequent fit-outs and M&E changes are a common reason fire stopping gets breached. Where fire-rated sealant is specified, we install it to the tested detail under the building’s permit-to-work arrangements.

For a site team at a college like Bellerbys College London, 1.1 miles west of Maze Hill, fire-rated sealing is best scheduled after the summer works. For an estates team at a campus like University of Greenwich, which lies west of Maze Hill, summer M&E works are normally followed by a round of penetration sealing.

Maze Hill is about 1 mile north-east of Greenwich, in Greater London. Anywhere in SE10, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. Maze Hill is one of 764 places we cover in Greater London.

Commercial sites across SE10, SE3 and E14 are covered for service penetrations. We cover commercial and managed buildings on Webb Road, The Avenue and Hardy Road. Sites close to Maze Hill are covered too, including Greenwich (1 mile south-west), Vanbrugh Park Estate (1 mile south-east), Westcombe Park (1 mile east), Blackheath (1 mile south) and Isle of Dogs (1 mile north-west). Further afield, our area takes in London (4 miles west), City of Westminster (7 miles west), Marylebone (7 miles west), Kensington (9 miles west), St Pancras (6 miles north-west) and Shoreditch (5 miles north-west).

Local landmarks in Maze Hill

Our process

At the end of each section, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. Where the sealant needs time to cure before use, we tell you and sign the area. Planning a London job such as one in Maze Hill starts with access. Send the building rules and access times with your enquiry.

  1. We start with your penetration schedule, drawings or specification.
  2. We plan the sequence of floors, risers and voids with you.
  3. Each opening is checked for wall or floor type, service, gap and depth.
  4. Foam, ordinary sealant and debris come out so the seal starts clean.
  5. Backing and fire-rated sealant are installed to the detail and tooled.
  6. We tell you about openings that need a different product.

What we need from you

  • Arrange parking or a loading space
  • For older buildings, check the asbestos register before work
  • Send any specification or drawings in advance

Do you need fire stopping in Maze Hill?

Some service penetrations were never sealed at all. They come to light during inspections, refits or when another trade lifts a tile.

Most enquiries start with something like this:

  • Improvised or mixed-product fire seals
  • Fire-rated sealant that has cracked or shrunk back
  • Unsealed openings around new pipes and cables
  • Non-fire-rated filler around services

In a hotel such as King William Hotel, which lies north of Maze Hill, new pipework or cabling through bedroom and corridor walls needs sealing with the specified product.

What your quote should include

  • Their public liability cover
  • Their approach to joint depth and backing
  • How they handle RAMS and site documents
  • Whether their applicators hold CSCS cards

How to choose a sealant contractor

General trades versus a specialist

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

Keeping the joints sound

Your facilities or cleaning team can help the joints last. Pass these on to them:

  • Look above ceilings when tiles are lifted for other jobs
  • Brief every trade that openings they make must be sealed
  • Settle who seals which penetrations at the start of a project
  • Check with the data sheet before painting over fire sealant

After the work, brief anyone else working in the area that the openings are now sealed. Any seal cut back for a new service needs reinstating to its tested detail using the same product.

Write fire stopping into the scope of any work crossing a compartment wall or floor. That way the opening is sealed while the trade and access are still there.

What shapes the price:

  • How much existing material needs removing

  • Induction, permit and paperwork requirements

What to include in your enquiry

A good diagnosis starts with the right details. Tell us:

  • Rough lengths or quantities, or drawings if you have them
  • Whether an asbestos survey exists
  • How the joints are reached, and at what height
  • The type of building and who uses it

Need a figure for a tender or a budget? Send the scope and any drawings, and we’ll return a fixed quote you can plan around. If you have questions first, phone 01277 525 020 or email the details over.
