Fire stopping for commercial buildings in Great Saling

We should be clear about what we do and don’t do. The designer, fire engineer or building control decides which fire stopping is required; sign-off sits with them too. What we bring is careful installation of the specified sealant, to the maker’s guidance. Most enquiries involve penetration schedules that need working through and old intumescent sealant that has split away, on joints between fire-resisting walls and floors, small duct penetrations where the tested detail allows and pipe penetrations. Looking for mastic applicators who cover Great Saling? We’ve been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.

Smaller places such as Great Saling still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.

Every job is signed off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Site staff or a sealant specialist?

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

Great Saling: questions and answers

Is Great Saling too small for you to travel to?

No. Small places get the same service as large ones. We work across Greater London and the South East. Good photographs up front let us bring everything on the first visit.

Would you work within a site like Braintree Community Hospital?

Yes. We work in healthcare settings as well as offices and schools. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Do you work in Scotland as well as England?

Scotland sets its own building regulations, with Technical Handbooks, and England uses Approved Document B. Wherever the site is, our work follows the specification and the tested detail.

Will you sign off the seals for us?

No. Sign-off isn’t ours to give, and we don’t hold a third-party installer certificate. We work to the specification and the manufacturer’s installation guidance.

How do you choose the sealant?

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

How long will the new sealant last?

Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.

Will you quote for a small job?

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.

Our process

Working in a building that stays open takes some planning. The work area is signed and kept contained, with routes through the building left open and move on in phases so staff and visitors can carry on around us. If others near Great Saling need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

  1. First we go through the drawings, schedule or specification for the seals and ask about anything unclear.
  2. Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
  3. Unsuitable fillers and loose debris are taken out of each opening.
  4. Mineral wool or other backing goes in wherever the detail asks.
  5. Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
  6. Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.

Before we start on site

  • Share the asbestos register for older buildings
  • Move anything stored against the joints
  • Send your site hours and access windows

Owners, agents and contractors

If you look after buildings for someone else, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.

Where services cross fire walls in Great Saling

For England, the fire stopping of penetrations is dealt with in Approved Document B. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. Either way, we install the specified product to its tested detail. Central London is about 37 miles from Great Saling. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls.

Industrial units on estates such as Goulds Farm Industrial Estate (to the south-east of Great Saling) often separate offices from warehouse space with fire-resisting walls, and new services through them need the specified seal. At a healthcare site like Braintree Community Hospital, which lies south-east of Great Saling, new services through compartment walls are a constant, and each needs the specified seal. Older community buildings such as Church of St James that have been rewired or given new heating can have service gaps through walls worth checking against the specification.

Great Saling is about 4 miles west of Braintree, in Essex. Anywhere in CM7, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. Great Saling is one of 644 places in Essex on our list. We also cover London, around 37 miles from Great Saling.

What sealant work can’t fix

Before quoting, we check that sealant is the right answer. It won’t put right:

  • Approving the work on behalf of building control
  • Walls or floors that aren’t fire-resisting to begin with
  • Fire risk assessments, a job for a competent assessor

Not sure which it is? You can call the office on 01277 525 020 or email the details over and we’ll tell you honestly before you book.

What we seal

  • Pipe penetrations
  • Service gaps in risers
  • Joints between fire-resisting walls and floors
  • Small duct penetrations where the tested detail allows
  • Cable penetrations
  • Linear gaps at wall heads

What affects the price in Great Saling

These are the things that shape the price:

  • Distance, for remote addresses
  • Phasing around occupants
  • Removal of failed or old sealant
  • Joint width, depth and condition

What a job costs comes down to the quantity of joints, what has to come out first and how the joints are reached. Call for a fixed quote once you have the details.

What we need to price the job

There’s no need for a formal survey. A few details are enough to get going:

  • What the building is and how it’s used
  • When you need the work done
  • A wide shot and a close-up of the area
  • The product your specification calls for

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to speak to us on 01277 525 020 or email us with what you know.

Aftercare for building managers

After handover, these steps help:

  • Check risers and ceiling voids after each round of works
  • Arrange inspection before areas are covered up
  • Brief every trade that openings they make must be sealed
  • Settle who seals which penetrations at the start of a project

Give the sealant its full cure time before ceilings, boxing or decoration go over it. Some fire-rated sealants accept paint and some don’t, and the data sheet says which.

Specify fire stopping early on refits, not as an afterthought. Details can then be picked to suit the actual pipes, cables and ducts.
