Fire stopping across Tye Green

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

After the work

Keep the joints in good shape with a few simple steps:

  • Treat an open penetration as a priority repair
  • Record which product was used where
  • Make fire stopping part of every scope that crosses a fire-resisting wall
  • Look above ceilings when tiles are lifted for other jobs

Allow the manufacturer’s stated cure time before boxing in or decorating. Not every fire-rated product can be painted, so check the product data first.

On fit-outs, get the fire-stopping specification agreed before the services go in. The designer can then choose details that suit the services planned, and installation follows the programme.

How we handle fire stopping in Tye Green

We are commercial sealant applicators, CHAS accredited and a Constructionline member, with CSCS-carded applicators on site. We don’t hold a third-party fire-stopping installer certificate and we’d rather say that up front. We install the specified fire-rated sealant to its tested detail, and our workmanship carries a 12-month guarantee. We work on pipe penetrations, linear gaps at wall heads and cable penetrations, and what we are called in for most is unsealed openings around new pipes and cables and unsealed joints where partitions meet the slab. Most enquiries from Tye Green start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Barn and farm-building conversions near places like Tye Green often combine new partitions with old walls. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.

We sign every job off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

How the job changes by surface

Masonry and concrete

Core-drilled holes are neat; broken-out ones rarely are. Each gap is measured where it is widest so we know it sits within the tested range, and any that don’t are flagged.

Metal pipes

Heat travels along metal pipework. If the detail needs something beyond sealant, we tell you.

Work for main contractors and building owners

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.

When you manage a building on behalf of an owner, 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.

On site: what to expect

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 your contact hears from us before we move to the next area. Rural sites near Tye Green may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.

  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. The specified backing and sealant go in to depth and are finished neatly.
  6. We tell you about openings that need a different product.

Before we start on site

  • Send asbestos survey details if the building is pre-2000
  • Make sure the joints can be reached
  • Have the specification and drawings to hand

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, call 01277 525 020 or email drawings and photos.

Common questions from Tye Green clients

Is hospital work, at somewhere like Saffron Walden Community Hospital, something you do?

Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Is Tye Green too far out for you?

Not at all. Tye Green is within our area. We work across Greater London and the South East. Good photographs up front let us bring everything on the first visit.

What if there’s asbestos in the old mastic?

Managing asbestos is the dutyholder’s responsibility, so we will ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.

Do the same rules apply to fire stopping in Scotland?

Building standards in Scotland are separate from England’s, and England uses Approved Document B. Wherever the site is, our work follows the specification and the tested detail.

Will you quote for a small job?

Small jobs are welcome alongside larger packages. Photos and a description are enough to start.

What changes on 2 September 2029?

For buildings in England, Approved Document B removes BS 476 references from 2 September 2029. Products are then judged on BS EN 13501-2 classifications. Scotland follows its own Technical Handbook, including clause 2.1.14 on service penetrations.

What about RAMS and site documents?

Requirements differ from site to site, so tell us what you need and we will confirm it when we quote.

Compartments and services around Tye Green

Tye Green lies roughly 38 miles out from central London. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls. Approved Document B is the English guidance that covers fire stopping around openings and penetrations. 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. We install whatever has been specified, to the product’s tested detail.

On a hospital site such as Saffron Walden Community Hospital, which lies north-west of Tye Green, fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits. Holiday works at schools like Wimbish Primary School often leave service openings to seal before pupils return.

When to call us in Tye Green

Physical damage is another reason seals stop doing their job. Maintenance work can knock a seal, cut it back for an extra cable or remove it with an old pipe, and the repair is often skipped.

Look out for the following:

  • Seals that don’t match their tested detail
  • Unsealed penetrations discovered above suspended ceilings
  • Damaged fire seals in risers and voids
  • Unsealed openings around new pipes and cables

Older community buildings such as St Paul's Mission Room that have been rewired or given new heating can have service gaps through walls worth checking against the specification.
