Fire stopping across Furze Platt

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

Fire stopping in Furze Platt

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. We close the openings listed on your schedule, using the specified sealant and detail. We work on pipe penetrations, service gaps in risers and cable penetrations, and the usual reasons a site gets in touch are snag lists that include open service penetrations and damaged fire seals in risers and voids. Facilities teams, main contractors and managing agents in Furze Platt tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Around Furze Platt, penetration and linear seals tend to be one-building jobs. Send the specification, drawings or photos of the openings and we’ll quote to suit.

We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Building owners, agents and FMs in Furze Platt

We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Sites in Furze Platt can sit alongside others in a wider programme across Windsor and Maidenhead.

Hospitality, education, healthcare, office and retail clients book us directly too. We plan around the way the building is used, so the building keeps working while we do.

Why deal with it now?

An open or wrongly sealed service penetration lets fire and smoke reach the next compartment much sooner than the building was designed for. While the openings can be reached, sealing them is normally straightforward. Left until ceilings are closed or a tenant moves in, the same work costs more access and more disruption. Small buildings around Furze Platt suffer from failed joints as much as large ones. Early resealing avoids the damage that follows a leak.

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

Why appoint us

  • One number for every site we cover
  • Old sealant cut out, never sealed over
  • Products installed to the manufacturer’s instructions
  • Our applicators hold CSCS cards

FAQs: Furze Platt

Would you work within a site like St Mark's Hospital?

Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.

Can you seal penetrations in a hotel in Furze Platt after a refit?

Yes. We install fire-rated and intumescent sealant where it is specified. Each seal follows the tested detail, and rooms are done in turn.

How long do sealant joints last?

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

Are you CHAS accredited?

Yes. We’re CHAS accredited and a Constructionline member.

Do you work to architects’ specifications?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.

Will you just go over the old 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.

Is Furze Platt in your area?

Yes. Sites across Furze Platt are covered, with one number for every area we cover.

Looking after the joints

After handover, these steps help:

  • Include service cupboards in routine inspections
  • Arrange inspection before areas are covered up
  • Check with the data sheet before painting over fire sealant
  • Agree the fire-stopping specification before services go in

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, by someone who knows the system.

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.

When it isn’t the sealant

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

  • Plastic pipes whose detail calls for a collar or wrap
  • Fire doors, dampers or other fire safety equipment
  • Writing the fire-stopping specification

Not sure which it is? You can phone 01277 525 020 or send details through our quote form and we will tell you honestly.

Service penetrations in Furze Platt buildings

At about 28 miles from central London, Furze Platt is within reach of the capital. Office refits around the commuter belt bring new cabling through fire-resisting walls. There are two care or nursing homes within about 2 miles of Furze Platt. Care settings depend on compartmentation, so service penetrations made during maintenance or refurbishment need sealing with the specified product. Where that’s fire-rated sealant, we install it to the manufacturer’s tested detail.

At a retail site such as Cliveden View Shopping Centre (under half a mile north-east of Furze Platt), walls between units may be fire-resisting, so services added in a refit need the specified seal. Wherever services are added at a hospital such as St Mark's Hospital, 0.7 miles south-west of Furze Platt, the compartment line has to be made good with the specified product. In a hotel such as Bear Hotel, 1.2 miles south-east of Furze Platt, new pipework or cabling through bedroom and corridor walls needs sealing with the specified product.

General trades versus a specialist

Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

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.

Our process

We follow your site rules from the start: signing in, inductions and any permit to work. Once we are cleared to begin, we take the joints in the sequence agreed with you. Work in places the size of Furze Platt is planned as a single visit where we can. Photos with rough sizes let us arrive with everything needed.

  1. We start with your penetration schedule, drawings or specification.
  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.
  5. Backing and fire-rated sealant are installed to the detail and tooled.
  6. Anything outside the detail is reported to you rather than sealed.

Preparing the site

  • Clear stock, furniture or equipment away from the joints
  • Tell us your opening times and when work is allowed
  • Point out any areas we must not close
