Need fire stopping in Jennett's Park?

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Common problems we fix in Jennett's Park

Physical damage is another reason seals stop doing their job. Maintenance work can knock a seal, cut it back for an extra cable or remove it with an old pipe.

Typical triggers for a call:

  • Unsealed penetrations discovered above suspended ceilings
  • Snag lists that include open service penetrations
  • Unsealed openings around new pipes and cables
  • Damaged fire seals in risers and voids

Theatres, wards and plant rooms at sites like Heatherwood Hospital, 1.9 miles to the east of Jennett's Park, all have compartment walls crossed by services.

What your quote should include

  • What the guarantee covers, and for how long
  • Their approach to joint depth and backing
  • Will RAMS and insurance details be available?
  • Are they CHAS accredited or on Constructionline?

Choosing a commercial sealant contractor

Fire stopping for commercial buildings in Jennett's Park

A lot of fire-stopping work comes after M&E installation, a refit or a tenant fit-out. New cable runs, replaced pipework and extra data routes all punch holes in compartment walls, often unnoticed. We close the openings listed on your schedule, using the specified sealant and detail. We work on cable penetrations, service gaps in risers and small duct penetrations where the tested detail allows, and what we are called in for most is fire-stopping items raised at inspection or handover and openings left by services added after handover. Whoever orders the work in Jennett's Park, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.

In places the size of Jennett's Park, fire-resisting walls and floors are found in schools, care homes, health centres and mixed-use buildings. Around those penetrations, fire-rated sealant is installed if specified, with depth, backing and gap all as tested.

A 12-month guarantee applies to all our work in Bracknell Forest. If an installation problem shows up, ring 01277 525 020 or email us and we’ll arrange a return visit.

Diagnose, treat, sign off

The first thing on site is a walk round with your contact, 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. If neighbouring businesses or buildings around Jennett's Park need work too, visits can be combined. Mention the building’s opening times and we’ll work within them.

  1. We read the specification, drawings or penetration schedule you send.
  2. Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
  3. Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
  4. Mineral wool or other backing goes in wherever the detail asks.
  5. Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
  6. If an opening needs something other than sealant, we tell you instead of improvising.

Before we start on site

  • Agree which areas must stay open
  • Let building users know which areas are affected
  • Send any specification or drawings in advance

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. For smaller jobs, photographs and a description will do.

Related advice

Jennett's Park: questions and answers

Can you work on a hospital site such as Heatherwood Hospital?

Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.

Can you seal around new services in a hotel near Jennett's Park?

Yes. We install fire-rated and intumescent sealant where it is specified. Work is done room by room so the hotel keeps trading; design and sign-off stay with the designer and building control.

Is Jennett's Park in your area?

Yes. Jennett's Park is in our area and the rest of Bracknell Forest. For a quote, give us a call on 01277 525 020 or use the quote form.

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.

Can you quote from photographs?

Many jobs can be quoted from photos, drawings or a joint schedule. Where they aren’t, we arrange a site visit.

What happens if old sealant might contain asbestos?

Managing asbestos is the dutyholder’s responsibility, so we’ll ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.

Do you seal on top of existing sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.

How the job changes by surface

Metal pipes

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

Small ducts

Ducts are only sealed with sealant where the detail allows it. Dampers and ductwork systems themselves are outside our work.

Cost factors for service penetrations

Your fixed quote is built from the real scope. It allows for:

  • Travel to remote or island sites
  • The site’s rules and procedures
  • Whether the work must be split into stages
  • How much existing material needs removing

Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.

What to include in your enquiry

Diagnosis starts before we arrive. Let us know:

  • Clear photographs of the problem areas
  • Approximate linear metres or a joint schedule
  • The product your specification calls for
  • Access details, including height

A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Share whatever details you have and we will fill any gaps with a visit.

Compartments and services around Jennett's Park

Bracknell, one of the planned towns of the twentieth century, takes in or adjoins Jennett's Park. Decades of new cabling and pipework in planned-town buildings can leave openings in compartment walls to seal with the specified product. Jennett's Park lies roughly 28 miles out from central London. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls.

Colleges such as Newbold College of Higher Education, 2.6 miles north-west of Jennett's Park, add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product. Office fit-outs on sites such as Bracknell Enterprise Centre, 1.4 miles to the west of Jennett's Park, add cabling and pipework through fire-resisting walls, and fire-rated sealant goes in where the specification calls for it.

When it isn’t the sealant

A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is any of the following:

  • Openings that need collars, wraps, batts or boards rather than sealant
  • Designing or specifying fire stopping, which sits with the designer or fire engineer
  • Gaps in walls that were never built as compartment walls

If in doubt, ring 01277 525 020 or use the quote form and we’ll say what we think.

Joints and surfaces we work on

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

Aftercare for building managers

For the best life from the joints:

  • Ask the designer to confirm details early on refits
  • Record which product was used where
  • Put resealing into every M&E and fit-out package
  • Leave fire sealant to cure fully before covering it

Once the seals are in, tell other trades they exist and must not be disturbed. If a seal has to be opened for a new service, it should be reinstated to the same detail.

On fit-outs, get the fire-stopping specification agreed before the services go in. Details can then be picked to suit the actual pipes, cables and ducts, and installation follows the programme.
