Fire stopping for businesses in Millbridge

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Building owners, agents and FMs in Millbridge

For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, and our applicators hold CSCS cards.

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

About our fire stopping in Millbridge

Where pipes, cables and other services cross a compartment wall or floor, the opening around them has to be closed so fire and smoke can’t move between compartments. Our part is installing fire-rated and intumescent sealant at those openings and along linear gaps, where the specification calls for it. Each seal follows the manufacturer’s tested detail rather than guesswork. The enquiries we see most involve head-of-wall gaps with no fire seal and fire-stopping items raised at inspection or handover, on small duct penetrations where the tested detail allows, linear gaps at wall heads and pipe penetrations. Whoever orders the work in Millbridge, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Rural conversions around Millbridge can put new fire-resisting partitions inside older structures. A penetration seal only performs as tested if product, substrate, service, gap and depth all match the detail.

Every job is signed 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 a job runs

We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. For a building around Millbridge, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.

  1. We ask for the product and detail your designer has specified.
  2. We sort the openings by the detail each one needs.
  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. We walk the completed areas with you and confirm the records agreed at quote stage.

What we need from you

  • Warn occupants and staff about the work
  • Send asbestos survey details if the building is pre-2000
  • Move anything stored against the joints

Getting a fixed quote

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 photos and a few notes.

Advice

Common problems we fix in Millbridge

When a seal departs from its tested detail, the evidence no longer covers it. An oversized gap, too shallow a bead, missing backing or two makers’ products combined are what we find most often.

What tends to prompt an enquiry:

  • Seals that don’t match their tested detail
  • Openings left by services added after handover
  • Fire-stopping items raised at inspection or handover
  • Head-of-wall gaps with no fire seal

In a building such as Church of St Mary the Virgin, any service penetration through a fire-resisting wall should be sealed to the specified detail.

What to look for in a quote

  • Their approach to joint depth and backing
  • How long is the guarantee, and what does it include?
  • Whether primer will be used where the manufacturer specifies it
  • What site paperwork they can supply

Our contractor checklist

Looking after the joints

Regular inspection catches problems early. Specifically:

  • Record which product was used where
  • Make fire stopping part of every scope that crosses a fire-resisting wall
  • Don’t let anyone top up a fire seal with the wrong product
  • Agree the fire-stopping specification before services go in

After every round of M&E works, check that the openings created have been sealed. Building it into each contractor’s sign-off keeps the walls intact.

Keep a register of where seals are and what they are made of. When a new service goes through, everyone knows which product and detail to match, and it helps at inspections.

Where services cross fire walls in Millbridge

Millbridge is about 37 miles from central London. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls; the gaps need the specified seal. In England, Approved Document B covers fire stopping of 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.

Wherever services are added at a hospital such as Chase Community Hospital, 5.7 miles to the south-west of Millbridge, the compartment line has to be made good with the specified product. On estates like Grovebell Industrial Estate (2.2 miles north-west of Millbridge), the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal.

Millbridge is about 2 miles south of Farnham, in Surrey. We cover Millbridge, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Millbridge is one of 379 places in Surrey on our list for service penetrations. We also cover Reading, some 21 miles away.

Work on service penetrations is covered throughout GU10, for business premises of every kind. Streets here include Shortfield Common Road, The Reeds Road and Fifield Lane, and sites on any of them can send details for a fixed quote. If your building is just outside Millbridge, we cover Shortfield Common (1 mile west), Frensham (1 mile south), Tilford Reeds (1 mile north-east), Lower Bourne (2 miles north) and Tilford Common (2 miles east). Nearby towns on our patch include Guildford (11 miles north-east), Woking (14 miles north-east), Camberley (11 miles north), Frimley (10 miles north), Haslemere (7 miles south-east) and Cranleigh (14 miles east).

Surface by surface

Drylining partitions

Holes in board are often cut larger than needed. If the gap exceeds the tested range, sealant alone won’t do, and the detail may call for board patching or another product.

Plastic pipes

Waste and drainage pipes through floors are a frequent case. The detail decides whether sealant alone is enough, and we will never swap a specified collar for sealant.

What sealant work can’t fix

Our job is the joint, not everything around it. Sealant alone won’t deal with:

  • Fire doors, dampers or other fire safety equipment
  • Writing the fire-stopping specification
  • Approving the work on behalf of building control

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

Joints and surfaces we work on

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

Questions we are asked in Millbridge

Can you work on a hospital site such as Chase Community Hospital?

Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Can you work at a site such as Grovebell Industrial Estate, by Millbridge?

Yes. We cover Millbridge and the area around it, including industrial estates, business parks and retail parks such as Grovebell Industrial Estate. A few photographs and the unit address let us price the work.

Will you sign off the seals for us?

No. Approval sits with the designer, principal designer or building control. We will confirm the products and details used, and you can tell us what other records you need at quote stage.

How long before the joints can be used?

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.

Is fire stopping in Scotland covered by different guidance?

Scotland sets its own building regulations, with Technical Handbooks, while England relies on Approved Document B. Either way, we install the specified sealant to its tested detail.

Do you work in Millbridge?

Yes. We cover Millbridge and the rest of Surrey, within our coverage of Greater London, South East England and Scotland. To discuss a job, phone 01277 525 020 or use the quote form.
