Fire stopping for Upper Harbledown sites

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

Surface by surface

Small ducts

Ducts are only sealed with sealant where the detail allows it. The ductwork, its supports and any dampers are for the ductwork contractor.

Cables and cable bundles

New data and power cables are the most common breach we see. We reseal around them to the specified detail, and any bundle too large for sealant alone is flagged.

Fire stopping in Upper Harbledown, done properly

Sealant is the specified answer for plenty of openings, such as metal pipes, cables and some small ducts where the detail covers them. Other openings need collars, wraps, batts, pillows or boards. If the detail calls for something other than sealant, we say so rather than force sealant into it. We work on joints between fire-resisting walls and floors, pipe penetrations and cable penetrations, and the failures we are asked to look at most are damaged fire seals in risers and voids and fire-rated sealant that has cracked or shrunk back. Facilities teams, main contractors and managing agents in Upper Harbledown tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Smaller places such as Upper Harbledown still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. 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. It covers how we prepared and applied the sealant.

Service penetrations in Upper Harbledown buildings

Three care or nursing homes sit less than 2 miles from Upper Harbledown. In a care home, any new pipe or cable through a fire-resisting wall should be sealed to the specified detail. A 2-mile radius around Upper Harbledown takes in plenty of hotels. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close.

In a retail centre such as Whitefriars Shopping Centre, 2.1 miles to the east of Upper Harbledown, any fire-resisting wall between units that is crossed by new services needs sealing to the tested detail. Campus buildings at universities such as University of Kent (to the north-east of Upper Harbledown) see constant changes to data and services, and fire-rated sealant goes in around new penetrations where it is specified.

Signs you need fire stopping in Upper Harbledown

Fire stopping can get squeezed at the end of a programme, or done by whoever is on site. That is how unsuitable products and improvised details end up in compartment walls.

Site and facilities staff are often the first to spot these:

  • Unsealed joints where partitions meet the slab
  • Hidden openings found during inspections
  • Expanding foam used as fire stopping
  • Seals disturbed by maintenance and left open

Workshops and IT rooms at colleges like Canterbury College, 2.5 miles to the east of Upper Harbledown, are re-serviced often, leaving penetrations to seal.

Comparing quotes

  • Proof of insurance
  • Which product they’ll use, and why it suits the joint
  • Can the work be phased to keep areas open?
  • Do they follow the manufacturer’s priming guidance?

Choosing a commercial sealant contractor

Leave it or put it right?

An unsealed opening affects more than fire safety: they also carry noise, draughts and smells between rooms. Sealing them to the specified detail deals with the fire risk first and the building feels the difference. For buildings around smaller places like Upper Harbledown, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.

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

Why appoint us

  • Old sealant cut out, never sealed over
  • Health and safety: CHAS accredited
  • Workmanship guaranteed for 12 months
  • Fixed quotes based on photos, drawings or a visit

Questions about Upper Harbledown

Is a smaller place like Upper Harbledown outside your area?

No. Places such as Upper Harbledown are covered as much as the big towns. We cover Greater London and the counties of the South East. Good photographs up front let us bring everything on the first visit.

Can you seal penetrations in a hotel in Upper Harbledown after a refit?

Yes, to the specification and the product’s tested detail. Work is done room by room so the hotel keeps trading; design and sign-off stay with the designer and building control.

Can you send site paperwork?

Each site asks for different documents, so tell us what you need and we’ll confirm it when we quote.

Do you work to architects’ specifications?

Yes. Send it with your enquiry, and we will price the work to it.

Do you take on multi-site work?

Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.

How do you choose the sealant?

The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.

Do you take on small jobs?

Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.

What sealant work can’t fix

Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:

  • Walls or floors that aren’t fire-resisting to begin with
  • Issuing fire ratings or certificates for seals
  • Openings that need collars, wraps, batts or boards rather than sealant

If in doubt, speak to us on 01277 525 020 or email the details over and we will say what we think before you book.

Surfaces we seal

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

Cost factors for service penetrations

A fixed quote reflects the actual work. It allows for:

  • Phasing around occupants
  • Specialist products, such as fire-rated or hygienic sealants
  • Joint width, depth and condition
  • Location, for remote and island sites

Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

What to include in your enquiry

A good diagnosis starts with the right details. Tell us:

  • Whether the building will be occupied during the work
  • Your programme or deadline
  • The asbestos register, for older buildings
  • Any specification or named product

To get a fixed quote, phone 01277 525 020 or email drawings and photos, telling us the site location and the nature of the job. You can also send details through our quote form.

On site: what to expect

A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself normally takes anything from one day to a planned run of visits, depending on the number of seals and the access, and our waste is bagged and taken away as we go. For a building around Upper Harbledown, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the 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. 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. We walk the completed areas with you and confirm the records agreed at quote stage.

Preparing the site

  • Have the specification and drawings to hand
  • Share the asbestos register for older buildings
  • Let us know about inductions and permits

Getting a fixed quote
