Fire stopping near Sarre

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

How we handle fire stopping in Sarre

On a fit-out or refurbishment, we follow the services contractors floor by floor. To price a package, ring 01277 525 020 or email a schedule or drawings with the schedule or marked-up drawings and the specified product data. Tell us what records you need and we’ll confirm with the quote. If you’re dealing with builders’ foam or ordinary silicone in compartment walls and open linear gaps along the top of fire-resisting walls, we can help, whatever the surface. Most enquiries from Sarre start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.

A job near Sarre is usually planned around one visit, so send the specification and photos first. Design and sign-off belong to the designer or building control; we install what’s specified.

The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we are clear about what is covered before work starts.

Diagnose, treat, sign off

Before we leave any area, the masking comes off, the area is cleaned and every joint is checked. If an area should be left alone while the sealant cures, we say how long and put signs out. For work around Sarre, we aim to finish in one visit, so photographs and measurements up front really help. That way the right products come on the day.

  1. We read the specification, drawings or penetration schedule you send.
  2. On site, each opening is checked against the tested detail it is meant to follow.
  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.

Getting the site ready

  • Warn occupants and staff about the work
  • Share the asbestos register for older buildings
  • Send any specification or drawings in advance

Advice

FAQs: Sarre

What happens to BS 476 references for fire stopping in Sarre?

Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.

Is Hedgend Industrial Estate, near Sarre, within your area?

Yes. Estates, retail parks and business parks around Sarre, Hedgend Industrial Estate among them, are all within reach. To start, just call 01277 525 020 or send photos by email with the unit, the joints involved and your access times.

What hours do you work?

Mention the site’s hours and access windows in your enquiry, and we will schedule the work to suit. You can reach the office between 8am and 5pm, Monday to Friday.

Can you work to our specification?

Yes. Include it with the drawings when you ask for a quote, and we’ll price the work to it.

When is resealing likely to be due?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

How many days will you need on site?

The duration is planned around your programme and the access we are given. We’ll give you an estimate of time on site when we quote.

What if there’s asbestos in the old mastic?

Managing asbestos is the dutyholder’s responsibility, so we’ll ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.

Signs you need fire stopping in Sarre

Fire stopping can get squeezed at the end of a programme, or done by whoever is on site. That is how unsuitable products and improvised details end up in compartment walls.

Common reasons buildings call us in:

  • Openings found when ceilings come down for a refit
  • Head-of-wall gaps with no fire seal
  • Fire-rated sealant that has cracked or shrunk back
  • Damaged fire seals in risers and voids

Hotels like Sarre Court Hotel (to the south-east of Sarre) are refurbished in phases, and each phase can open up compartment walls.

What your quote should include

  • How they handle RAMS and site documents
  • Their approach to joint depth and backing
  • What level of public liability insurance do they hold?
  • Their plan for phasing and protecting the area

Our contractor checklist

How the quote is worked out

Each job is priced on its own details. The main factors are:

  • Location, for remote and island sites
  • The product specified
  • The total length or number of joints
  • Whether the work must be split into stages

Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.

What to include in your enquiry

Diagnosis starts before we arrive. Let us know:

  • Any dates the work must fit around
  • Drawings or a marked-up plan, if available
  • Whether the building will be occupied during the work
  • How the joints are reached, and at what height

Send us photos, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.

Owners, agents and contractors

CHAS accredited and a Constructionline member, we are straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.

Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.

Looking after the joints

Once the work is signed off, these steps help:

  • Brief every trade that openings they make must be sealed
  • Report damaged or disturbed seals as soon as they’re spotted
  • Look above ceilings when tiles are lifted for other jobs
  • Arrange inspection before areas are covered up

Keep the product data and installation details with the building’s fire safety information. Anyone resealing later needs to know which product and detail were used.

Keep a register of where seals are and what they are made of. It tells the next contractor exactly what to reinstate, and it helps at inspections.

When it isn’t the sealant

We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:

  • Deciding what a wall or floor needs, which belongs to the designer
  • Plastic pipes whose detail calls for a collar or wrap
  • Signing off or certifying a building’s fire stopping

If you are not sure, just call the office on 01277 525 020 or email drawings and photos and we will give you a straight answer.

Where we work in Sarre

Where services cross fire walls in Sarre

Central London is about 58 miles from Sarre. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls. Approved Document B is the English guidance that covers fire stopping around openings and penetrations. From 2 September 2029, BS 476 references are being taken out of Approved Document B, leaving BS EN 13501-2 classification as the route, subject to the Government’s transitional arrangements. What we install is set by the specification, and it goes in to the tested detail.

In a school such as St Nicholas At Wade Church of England Primary School, fire-rated sealant goes in around service penetrations where it is specified. On estates like Hedgend Industrial Estate (1.5 miles north-east of Sarre), the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal.

Sarre is about 5 miles south-east of Herne Bay, in Kent. Sarre sits inside our coverage and the rest of Kent, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Sarre is one of 931 places in Kent on our list. For work in that direction, see our London page (58 miles or so).

Commercial sites across CT7 are covered for service penetrations. Buildings on Island Road, Old Road and Chantry Park are within our area. We also cover St Nicholas at Wade (1 mile north-east), West Stourmouth (1 mile south), East Stourmouth (2 miles south), Monkton (2 miles east) and Upstreet (2 miles south-west). Further afield, our area takes in Canterbury (8 miles south-west), Margate (7 miles north-east), Dover (14 miles south), Ramsgate (7 miles east), Broadstairs (8 miles east) and Whitstable (9 miles west).
