Fire stopping across Messing

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

About our fire stopping in Messing

On a fit-out or refurbishment, we follow the services contractors floor by floor. We work from your penetration schedule or marked-up drawings alongside the manufacturer’s details. Tell us what records you need and we’ll confirm with the quote. We work on service gaps in risers, cable penetrations and joints between fire-resisting walls and floors, and what we’re called in for most is seals that don’t match their tested detail and non-fire-rated filler around services. Whoever orders the work in Messing, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.

Smaller places such as Messing 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 the quote explains what it covers.

Doing it in-house

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

After the work

Your facilities or cleaning team can help the joints last. Share these points with them:

  • Don’t let anyone top up a fire seal with the wrong product
  • Check risers and ceiling voids after each round of works
  • Get seals inspected before ceilings and boxing close
  • Agree the fire-stopping specification before services go in

Store the specified product details somewhere the next contractor can find them. Anyone resealing later needs to know which product and detail were used.

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 instead of being left for someone else.

What sets the cost

Sealant work doesn’t have a standard rate, since sites vary so much. What we take into account:

  • Quantities, in metres or numbers
  • Specialist products, such as fire-rated or hygienic sealants
  • Joint width, depth and condition
  • Distance, for remote addresses

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

What we need to price the job

We can often quote from photographs and a few details. It helps to include:

  • The site address and postcode
  • Anything awkward about access or site hours
  • Photos of the joints, close up and from further back
  • The type of building and who uses it

Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. The easiest way is to speak to us on 01277 525 020 or email a schedule or drawings.

When something else is needed

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

  • Signing off or certifying a building’s fire stopping
  • Walls or floors that aren’t fire-resisting to begin with
  • Plastic pipes whose detail calls for a collar or wrap

If in doubt, call the office on 01277 525 020 or email us and we will say what we think.

Joints and surfaces we work on

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

Questions about Messing

Is a smaller place like Messing outside your area?

Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Good photographs up front let us bring everything on the first visit.

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

References to BS 476 classes are being removed from Approved Document B from 2 September 2029, after which BS EN 13501-2 classification is the route, subject to transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.

How do you choose the sealant?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

Are you CHAS accredited?

Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.

Can you fit around our working hours?

The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.

How do I request a quote?

It works in four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photographs and a postcode.

How long does a typical visit take?

That varies with the scale of the job, but the work usually takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence. Larger or phased jobs take longer, and we will give you a timescale with the quote.

Our process

We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. For a building around Messing, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.

  1. First we confirm the product and tested details named in the specification.
  2. Openings are measured and grouped by detail.
  3. Improvised fillers and failed sealant are removed.
  4. Where the detail needs backing, it goes in at the stated depth.
  5. We gun the sealant in to the specified depth around each service and tool it.
  6. Completed areas are checked with you, with the records agreed when we quoted.

What we need from you

  • Tell us your opening times and when work is allowed
  • Send asbestos survey details if the building is pre-2000
  • Make sure the joints can be reached

Quotes

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

Advice

Signs you need fire stopping in Messing

On a busy project, programme pressure can mean fire stopping is rushed or left to whichever trade is closest. That is how unsuitable products and improvised details end up in compartment walls and later need putting right.

Common reasons buildings call us in:

  • Service penetrations left open after M&E works
  • Fire seals cut back for extra cables and never reinstated
  • Openings found when ceilings come down for a refit
  • Seals that don’t match their tested detail

For a school such as Messing Primary School, penetration sealing fits best at the end of the summer works.

What to look for in a quote

  • Will failed sealant be removed rather than covered?
  • Their pre-qualification and accreditations
  • Their approach to joint depth and backing
  • How they handle RAMS and site documents

Questions to ask before you appoint anyone

Where services cross fire walls in Messing

Messing lies roughly 43 miles out from central London. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls. Fire stopping of openings and penetrations in England falls under Approved Document B. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. What we install is set by the specification, and it goes in to the tested detail.

In a building such as Church of All Saints (messing), any service penetration through a fire-resisting wall should be sealed to the specified detail. For a building at a site such as Threshelfords Business Park, 1.4 miles to the west of Messing, a check of penetration seals after each fit-out is good practice.

Messing is about 5 miles north-east of Witham, in Essex. We send applicators to Messing for service penetrations. 644 places across Essex fall within our area, including Messing. Our London page has more on work in that area, about 43 miles away.
