Common questions from Snow Hill clients

Is Snow Hill off your patch?

Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Is Silverwood Industrial Estate, near Snow Hill, within your area?

Yes. Estates, retail parks and business parks around Snow Hill, Silverwood Industrial Estate among them, are all within reach. To start, just speak to us on 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.

Is BS 476 being phased out?

For buildings in England, Approved Document B removes BS 476 references from 2 September 2029. Classification to BS EN 13501-2 becomes the expected evidence, though transitional rules apply. In Scotland, the Technical Handbook sets its own guidance, including clause 2.1.14 on service penetrations.

Is sealant suitable for all service openings?

No. Each fire-rated sealant is tested for particular services, gap sizes and substrates. If an opening falls outside, it needs another solution.

What do BS EN 1366-3 and BS EN 13501-2 mean?

The tests are BS EN 1366-3 for penetrations and BS EN 1366-4 for linear joints, and classification is to BS EN 13501-2. EI 60 means integrity and insulation for 60 minutes in the tested arrangement; installing to the detail is what carries that across to site.

What do you charge?

Each job is quoted on its own details. For yours, speak to us on 01277 525 020 or send details through our quote form with a description of the work.

Is the work guaranteed?

Yes, for 12 months. If our installation fails in that time, we return and fix it.

How we handle fire stopping in Snow Hill

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 will confirm with the quote. We work on linear gaps at wall heads, small duct penetrations where the tested detail allows and service gaps in risers, and what we are called in for most is seals disturbed by maintenance and left open and unsealed openings around new pipes and cables. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Snow Hill is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Barn and farm-building conversions near places like Snow Hill 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 stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application.

Honest limits

We check first that sealant really is the fix. It won’t put right:

  • Approving the work on behalf of building control
  • Fire risk assessments, a job for a competent assessor
  • Openings that need collars, wraps, batts or boards rather than sealant

Not sure which it is? You can call 01277 525 020 or use the quote form and we’ll tell you honestly.

Surfaces we seal

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

Fire stopping in Snow Hill: the local picture

Fire stopping of openings and penetrations in England falls under 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. We install whatever has been specified, to the product’s tested detail. A 2-mile radius around Snow Hill takes in several hotels. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close.

On estates like Silverwood Industrial Estate, which lies south-west of Snow Hill, the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal. On a hospital site such as Queen Victoria Hospital (3.7 miles east of Snow Hill), fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits. For a hotel such as Copthorne Hotel Effingham Park, which lies north-west of Snow Hill, penetration seals are worth checking after any refit or services upgrade.

Should maintenance staff do it?

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

Surface by surface

Drylining partitions

Plasterboard partitions are tested as a specific construction. We check that the product’s detail covers that partition type and board thickness before sealing.

Risers and ceiling voids

Risers and ceiling voids hold most of a building’s service penetrations. Access is often tight, so we agree it with you in advance.

Cost factors for service penetrations

There’s no standard rate for sealant work, since sites vary so much. What we take into account:

  • Any access equipment needed
  • Quantities, in metres or numbers
  • Working within restricted access windows
  • Travel to remote or island sites

The product called for affects the cost, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site rules also count.

Before you send an enquiry

We can often quote from photos and a few details. Please tell us:

  • Photos of the joints, close up and from further back
  • Asbestos survey details if the building is older
  • Where the site is, with the postcode
  • Any dates the work must fit around

To get a fixed quote, ring 01277 525 020 or email the details over with the site address and an outline of the work. Our quote form is another easy route.
