Fire stopping near Russell Hill

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

For managing agents and facilities managers

We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Russell Hill can form part of a wider programme.

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.

About our fire stopping in Russell Hill

No fire sealant works on its own: its test evidence covers one product in one kind of wall or floor, with set services, gaps, depths and backing. We match each opening to that detail before any sealant goes in, and we say so if it doesn’t fit. We work on linear gaps at wall heads, service gaps in risers and joints between fire-resisting walls and floors, and what we are called in for most is head-of-wall gaps with no fire seal and old intumescent sealant that has split away. Whoever orders the work in Russell Hill, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Taller residential buildings in London may fall under the Building Safety Act’s higher-risk regime, where fire-stopping records get close attention. We install what the designer or fire engineer has specified, and if you need records of the work, tell us and we’ll confirm with the quote.

Every job we finish is backed by a 12-month workmanship guarantee, in Russell Hill as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

General trades versus a specialist

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Questions we’re asked in Russell Hill

Will you work in a care home in Russell Hill without moving residents out?

Yes. Care settings are planned area by area, at times agreed with the home. Tell us about any infection-control or safeguarding requirements and we’ll work to them.

Do you cover business parks and estates near Russell Hill, such as Lysander Road Airport Industrial Estate?

Yes. We cover Russell Hill and the area around it, including industrial estates, business parks and retail parks such as Lysander Road Airport Industrial Estate. Send details of the unit and the work through our quote form for a quick quote.

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 happens if old sealant might contain asbestos?

The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.

Do you need to see the site first?

Many jobs can be quoted from photos, drawings or a joint schedule. Where they aren’t, we arrange a site visit.

How soon can the area be used again?

That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.

How long do sealant joints last?

It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.

From enquiry to sign-off

Tell us your site hours and access windows and we will plan around them. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. In Russell Hill, most buildings stay in use during the work, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.

  1. We ask for the product and detail your designer has specified.
  2. We sort the openings by the detail each one needs.
  3. Old or wrong materials are cut out.
  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. We walk the completed areas with you and confirm the records agreed at quote stage.

Preparing the site

  • Share the asbestos register for older buildings
  • Explain the parking and delivery arrangements
  • Make sure the joints can be reached

Advice

Common problems we fix in Russell Hill

Some seals fail because the wrong product went in: expanding foam or a general-purpose sealant pushed into a gap to tidy it. It may look closed, but it has no tested fire performance in that position.

Clients normally get in touch after noticing something like this:

  • Open linear gaps along the top of fire-resisting walls
  • Unsealed openings around new pipes and cables
  • Old intumescent sealant that has split away
  • Seals disturbed by maintenance and left open

For a unit at a site such as Lysander Road Airport Industrial Estate (less than half a mile north-east of Russell Hill), new power or data runs between office and warehouse can breach a compartment wall.

What to look for in a quote

  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Whether old or failed sealant will be cut out, not overlaid
  • How the joint faces will be prepared and primed
  • How they handle RAMS and site documents

Our contractor checklist

What sealant work can’t fix

Our job is the joint, not everything around it. On its own, sealant can’t deal with:

  • Deciding what a wall or floor needs, which belongs to the designer
  • Reviewing a building’s overall fire safety
  • Issuing fire ratings or certificates for seals

Not sure which it is? You can phone 01277 525 020 or email drawings and photos and we’ll tell you honestly before you book.

Surfaces we seal

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

Compartments and services around Russell Hill

There are nine care or nursing homes within about 2 miles of Russell Hill. Care settings depend on compartmentation, so service penetrations made during maintenance or refurbishment need sealing with the specified product. Where that’s fire-rated sealant, we install it to the manufacturer’s tested detail. London’s office and residential buildings are refitted constantly, and each round of cabling or pipework can leave open penetrations. Penetrations are sealed with the specified product, to its tested detail, under the building’s own permit rules.

Large healthcare estates like Purley War Memorial Hospital (to the south-east of Russell Hill) change their services often, so penetration seals are worth checking after M&E work. In a hotel such as London Croydon Aerodrome Hotel (0.5 miles north-east of Russell Hill), new pipework or cabling through bedroom and corridor walls needs sealing with the specified product.

Russell Hill is about 1 mile north of Purley, in Greater London. If you are looking for fire stopping in Russell Hill, we can help, as we do across Greater London.

Why act early in Russell Hill

Inspections and handover checks often pick up fire stopping. Late discoveries can delay handover while openings are reopened and resealed, so earlier action pays back. In Russell Hill, each extra visit means more notices, permits and disruption, so cutting the old sealant out fully and doing it right once is the better route.

The price depends on how many linear metres there are, how much old material needs removing and the access. Call for a quote when you’re ready.

Why us?

  • One number for every site we cover

  • Workmanship guaranteed for 12 months
