How we handle fire stopping in Hanworth

Most of our fire stopping work happens after the building is up. New cable runs, replaced pipework and extra data routes all punch holes in compartment walls, and they are easy to forget. Those on your schedule are closed with the specified product. We work on cable penetrations, pipe penetrations and service gaps in risers, and what we are called in for most is fire-stopping items raised at inspection or handover and fire seals cut back for extra cables and never reinstated. Facilities teams, main contractors and managing agents in Hanworth tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Converted and extended buildings around places like Hanworth can mix old and new construction, so it’s worth confirming the wall or floor type before choosing the seal. The right product depends on the wall or floor and the services passing through, and we’ll tell you if the detail calls for something other than sealant.

A 12-month guarantee applies to all our work. Should something we installed fail, phone 01277 525 020 or email drawings and photos and we will come back to it.

Quoting for work in Hanworth

There’s no standard rate for sealant work, since sites vary so much. What we look at:

  • Quantities, in metres or numbers
  • How accessible the joints are
  • The site’s rules and procedures
  • Distance, for remote addresses

No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Details that help us quote

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

  • Anything awkward about access or site hours
  • Where the site is, with the postcode
  • A wide shot and a close-up of the area
  • Your programme or deadline

Tell us about the building, the joints and when you need the work done, and we’ll put a fixed quote together. The easiest way is to give us a call on 01277 525 020 or send photos by email.

Leave it or put it right?

An improvised seal can look finished while offering no tested performance. The fix is to remove it and reinstall to the detail. In a smaller place such as Hanworth, getting a contractor back for a second visit takes time, so we’d suggest renewing all the joints that are going, not just the worst.

A quote for service penetrations depends on quantities, condition and access. Call for a quote.

Penetration seals near Hanworth

Hanworth lies roughly 30 miles out from central London. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls. Hanworth is part of, or right next to, Bracknell, which was built as a planned town. Decades of new cabling and pipework in planned-town buildings can leave openings in compartment walls to seal with the specified product.

In a building such as St Michael and St Mary Magdalene's Church, any service penetration through a fire-resisting wall should be sealed to the specified detail. Workshops and IT rooms at colleges like Newbold College of Higher Education, 2.4 miles north of Hanworth, are re-serviced often, leaving penetrations to seal. Large healthcare estates like Broadmoor Hospital (to the south of Hanworth) change their services often, so penetration seals are worth checking after M&E work.

Hanworth is about 1 mile south of Bracknell, in Bracknell Forest. Hanworth sits inside our coverage and the rest of Bracknell Forest, with the same fixed quotes and 12-month guarantee as everywhere else. Across Bracknell Forest, 48 places are covered, including Hanworth. We also cover Reading, some 10 miles away.

Our process

A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself usually takes a single visit for a short list of penetrations, or a phased programme for a whole building, and we clear our waste as we work. What matters most for a job in Hanworth is a clear list of what needs doing, so send photos of each area. A fixed quote follows.

  1. We ask for the product and detail your designer has specified.
  2. Openings are measured and grouped by detail.
  3. Improvised fillers and failed sealant are removed.
  4. Mineral wool or other backing is fitted where required.
  5. We gun the sealant in to the specified depth around each service and tool it.
  6. Completed areas are checked with you, with the records agreed when we quoted.

Before we start on site

  • Have the specification and drawings to hand
  • Clear stock, furniture or equipment away from the joints
  • Send asbestos survey details if the building is pre-2000

Get a fixed quote

Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. Smaller jobs need nothing more than photographs and a few notes.

Surface by surface

Plastic pipes

Plastic waste pipes through slabs come up often. Whether sealant alone is acceptable depends entirely on the tested detail, and we won’t substitute it for a specified collar.

Cables and cable bundles

Data cabling added after handover is a regular cause of open service penetrations. Openings around new cables are resealed to the detail.

Keeping the joints sound

Regular inspection catches problems early. Specifically:

  • File the specified details where the next contractor can find them
  • Look above ceilings when tiles are lifted for other jobs
  • Arrange inspection before areas are covered up
  • Make fire stopping part of every scope that crosses a fire-resisting wall

After the work, brief anyone else working in the area that the openings are now sealed. If a seal has to be opened for a new service, it should be reinstated to the same detail using the same product.

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

Your questions answered

Will you plan work around the academic year at somewhere like Newbold College of Higher Education?

Yes. We plan campus work around teaching, exams and residence turnarounds. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Will you take on work at estates like Longshot Lane Industrial Estate, close to Hanworth?

Yes, sites like Longshot Lane Industrial Estate are within our area, along with the rest of Hanworth. Send details of the unit and the work through our quote form for a quick quote.

Is Hanworth in your area?

Yes. Hanworth is in our area. For a quote, call the office on 01277 525 020 or email us.

What do you charge?

Every job gets its own fixed quote. To get one, give us a call on 01277 525 020 or email drawings and photos with a description of the work.

Do you work to architects’ specifications?

Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.

How long will the new sealant last?

It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.

Is sealant suitable for all service openings?

No. A sealant’s evidence covers set services, gaps and wall or floor types. If an opening falls outside, it needs another solution.

Honest limits

Being straight saves everyone time. New sealant won’t cure:

  • Plastic pipes whose detail calls for a collar or wrap
  • Writing the fire-stopping specification
  • Approving the work on behalf of building control

If you are not sure, just call the office on 01277 525 020 or send photos by email and we will give you a straight answer.
