About our fire stopping in Tilford Reeds

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. We work to the product’s tested detail for every seal. Site teams most often ask us about snag lists that include open service penetrations and unsealed joints where partitions meet the slab, on service gaps in risers, small duct penetrations where the tested detail allows and linear gaps at wall heads. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Tilford Reeds, preparation and product choice get the time they need.

Around smaller places like Tilford Reeds, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.

We stand by our work: 12 months, guaranteed. That covers our preparation and application.

Tilford Reeds: questions and answers

Is a hospital such as Farnham Community Hospital somewhere you can work?

Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Can work at a site such as University for the Creative Arts fit around teaching?

Yes. Education sites normally want the work in vacations or in phases during term, and we plan to suit. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Are you members of a third-party fire-stopping installer scheme?

No. We are not members of a third-party fire-stopping installer scheme. We are CHAS accredited and a Constructionline member, and our applicators are CSCS-carded. If your contract requires third-party installer certification, we are not the right fit for that package.

When can the area be used after sealing?

Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.

Does weather matter for sealant work?

Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.

Are you insured?

Yes. We’re fully insured, and the certificate can go with your quote.

Will you sign off the seals for us?

No. Sign-off isn’t ours to give, and we don’t hold a third-party installer certificate. Our part is fitting the specified product to its tested detail, and any records you need can be confirmed with the quote.

General trades versus a specialist

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

What sealant work can’t fix

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

  • Construction that lacks the fire resistance the seal relies on
  • Fire doors, dampers or other fire safety equipment
  • Large openings beyond what any sealant detail covers

If in doubt, ring 01277 525 020 or email drawings and photos and we will say what we think.

Joints and surfaces we work on

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

Surface by surface

Metal pipes

Metal pipes conduct heat, so their details often call for extra measures along the pipe, and the tested detail may ask for insulation beyond the wall. If the detail needs something beyond sealant, we tell you.

Linear joints

Linear joints run along the head of a wall, at a slab edge or between two fire-resisting elements. BS EN 1366-4 testing sets the joint widths, depths, backing and movement a seal covers and the installation has to fit inside those limits.

Why act early in Tilford Reeds

Inspections and handover checks often pick up fire stopping. Finding unsealed or improvised openings late can hold up a programme. One visit to deal with every failing joint makes more sense than several trips to a place like Tilford Reeds. Send photos of each area and we’ll quote for the lot.

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.

After the work

Cleaning and maintenance staff play a part too. Pass these on to them:

  • Ask which product is in place before decorating
  • Put resealing into every M&E and fit-out package
  • Don’t let anyone top up a fire seal with the wrong product
  • Get seals inspected before ceilings and boxing close

Add risers, plant rooms and ceiling voids to routine fire-stopping checks. Watch for cracked sealant, new services with no seal and openings that have grown.

Ask every contractor who works in risers or voids to report openings they create. Small habits like this stop openings building up.

Where services cross fire walls in Tilford Reeds

Central London is about 36 miles from Tilford Reeds. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls. Fire stopping of openings and penetrations in England falls under Approved Document B. 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. Either way, we install the specified product to its tested detail.

Hospital estates such as Farnham Community Hospital (to the north of Tilford Reeds) are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail. Campus buildings at universities such as University for the Creative Arts (2.9 miles north-west of Tilford Reeds) see constant changes to data and services, and fire-rated sealant goes in around new penetrations where it is specified. For a building at a site such as The Sands Business Centre, 2.3 miles to the north of Tilford Reeds, a check of penetration seals after each fit-out is good practice.

Diagnose, treat, sign off

A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. On site, the work typically takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence, and we clear our waste as we work. Smaller jobs around Tilford Reeds can be grouped with others nearby. You’ll have a fixed quote before work starts.

  1. The specification and schedule come first, so we know which details apply.
  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. Unsuitable material is removed and the opening cleaned so the seal starts clean.
  5. The specified backing and sealant go in to depth and are finished neatly.
  6. Anything outside the detail is reported to you rather than sealed.

Before we start on site

  • Confirm the product named in the specification
  • Clear stock, furniture or equipment away from the joints
  • Tell staff and tenants when we’ll be in
