Fire stopping across Farnborough

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

What affects the price in Farnborough

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

  • The product specified
  • The site’s rules and procedures
  • Whether the work must be split into stages
  • Distance, for remote addresses

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

Details that help us quote

A good diagnosis starts with the right details. Let us know:

  • Drawings or a marked-up plan, if available
  • The product your specification calls for
  • The postcode of the building
  • Whether the building will be occupied during the work

Need a figure for a tender or a budget? We’ll quote against your scope and drawings you can plan around. For a chat about it beforehand, give us a call on 01277 525 020 or use the quote form.

Fire stopping in Farnborough, done properly

For main contractors, our fire stopping package slots in after the M&E trades have finished in an area. We work from your penetration schedule or marked-up drawings and the specified product data. Tell us what records you need and we will confirm with the quote. If you have openings left by services added after handover and open linear gaps along the top of fire-resisting walls, we can put it right, on cable penetrations, joints between fire-resisting walls and floors and small duct penetrations where the tested detail allows alike. A single leaking joint is often how a building in Farnborough first comes to us: we look at the rest while we’re there and tell you what we find.

In a town like Farnborough, penetration seals normally need attention after other trades have been through. Checking after M&E works is good practice, and we will seal what’s found where fire-rated sealant is the specified product.

Building owners and contractors get the same cover: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

After the work

After handover, these steps help:

  • Put resealing into every M&E and fit-out package
  • Record which product was used where
  • Ask the designer to confirm details early on refits
  • Include service cupboards in routine inspections

Keep the product data and installation details with the building’s fire safety information. It makes later repairs much easier to match.

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

Site staff or a sealant specialist?

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.

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

What the job involves on each surface

Risers and ceiling voids

Risers and ceiling voids hold most of a building’s service penetrations. Access to these areas is planned with you in advance.

Metal pipes

Metal pipes conduct heat, so their details often call for extra measures along the pipe, and some details add wrapping or a set length of insulation. We follow whatever the detail requires and flag anything we can’t match.

Diagnose, treat, sign off

We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. In a town such as Farnborough, most jobs are single buildings. We start with your photos, drawings or a site visit, then send a fixed quote.

  1. First we confirm the product and tested details named in the specification.
  2. Openings are measured and grouped by detail.
  3. Improvised fillers and failed sealant are removed.
  4. Where the detail needs backing, it goes in at the stated depth.
  5. Fire-rated or intumescent sealant goes in around the services and is tooled off.
  6. We walk the completed areas with you and confirm the records agreed at quote stage.

Before we start on site

  • Tell staff and tenants when we will be in
  • Agree which areas must stay open
  • For older buildings, check the asbestos register before work

Honest limits

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

  • Fire doors, dampers or other fire safety equipment
  • Designing or specifying fire stopping, which sits with the designer or fire engineer
  • Large openings beyond what any sealant detail covers

If you are not sure, just ring 01277 525 020 or send photos by email and we’ll give you a straight answer.

Surfaces we seal

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

Fire stopping around Farnborough: points for this area

Farnborough lies roughly 32 miles out from central London. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls. Farnborough has three care or nursing homes no more than 2 miles away. Care homes rely on fire-resisting walls and floors, and maintenance work that breaks through them leaves openings to seal. We install fire-rated sealant to the tested detail where it is specified.

For a building such as Church of St Christopher, new heating or data runs are the usual reason penetrations need sealing. Hotels like Village Hotel, 0.6 miles to the south-east of Farnborough, are refurbished in phases, and each phase can open up compartment walls. On a hospital site such as Frimley Park Hospital (2.1 miles north-east of Farnborough), fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits.

Farnborough is about 31 miles south-west of City of Westminster, in Hampshire. Any commercial site in Farnborough is covered. Our Hampshire coverage takes in 723 places, from busy centres to rural villages. Reading is covered too, around 14 miles from Farnborough.

Your questions answered

Can you work around term dates at a campus such as The Sixth Form College Farnborough?

Yes, holiday working periods are the norm on campus jobs. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Can you work in a care home near Farnborough with residents in?

Yes, with the manager deciding the order and timing of rooms. Any site rules, from signing in to infection control, are agreed before we start.

Can the sealant be colour-matched?

Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We will confirm the colours available for the specified product.

Can you handle several sites?

Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.

Does the weather affect the work?

For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.

Who decides which product is used?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

How do I request a quote?

There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photos and a postcode.
