How we handle fire stopping in Rookley Green

For main contractors, our fire stopping package slots in after the M&E trades have finished in an area. To price a package, speak to us on 01277 525 020 or email a schedule or drawings with the schedule or marked-up drawings. Tell us what records you need and we’ll confirm with the quote. We work on pipe penetrations, linear gaps at wall heads and small duct penetrations where the tested detail allows, and the failures we are asked to look at most are unsealed joints where partitions meet the slab and fire seals cut back for extra cables and never reinstated. Looking for mastic applicators who cover Rookley Green? We have been sealing commercial buildings since 2005, with CSCS-carded applicators.

Rural conversions around Rookley Green can put new fire-resisting partitions inside older structures. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.

We stand by our work: 12 months, guaranteed. That covers our preparation and application.

Fire stopping in Rookley Green: the local picture

For England, the fire stopping of penetrations is dealt with in Approved Document B. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. What we install is set by the specification, and it goes in to the tested detail.

On a hospital site such as Whitecroft Hospital (1.8 miles north-west of Rookley Green), fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits.

Rookley Green is about 3 miles south of Newport, in the Isle of Wight. We cover Rookley Green and the rest of the Isle of Wight, with the same fixed quotes and 12-month guarantee as everywhere else. 125 places across the Isle of Wight fall within our area, Rookley Green among them. Our Portsmouth page has more on work in that area (14 miles or so).

Rookley Green: questions and answers

Do you take on work at healthcare sites like Whitecroft Hospital?

Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Is a smaller place like Rookley Green outside your area?

Not at all. Rookley Green is within our area. We cover Greater London and the counties of the South East. Good photos up front let us bring everything on the first visit.

Do you certify or sign off fire stopping?

No. Sign-off belongs to the designer or building control, not the installer. We’ll confirm the products and details used.

Is any job too small?

We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.

Can one quote cover more than one building?

Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.

Do you seal on top of existing sealant?

No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.

How long does a job like this take?

The duration is planned around your programme and the access we are given. We will give you an estimate of time on site when we quote.

Looking after the joints

Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:

  • Report damaged or disturbed seals as soon as they’re spotted
  • Settle who seals which penetrations at the start of a project
  • Keep general-purpose fillers away from compartment walls
  • Check risers and ceiling voids after each round of works

Give the sealant its full cure time before ceilings, boxing or decoration go over it. Some fire-rated sealants accept paint and some don’t, so check the product data first.

Specify fire stopping early on refits, not as an afterthought. The designer can then choose details that suit the services planned, and installation follows the programme.

What the job involves on each surface

Small ducts

We seal around ducts only within what the tested detail covers. The ductwork, its supports and any dampers are for the ductwork contractor.

Plastic pipes

Waste and drainage pipes through floors are a frequent case. Whether sealant alone is acceptable depends entirely on the tested detail, and we won’t substitute it for a specified collar.

Signs you need fire stopping in Rookley Green

A common fault is a product that was never fire-rated in the first place: builders’ foam or ordinary silicone used to fill a hole. It may look closed, but it has no tested fire performance in that position.

Clients usually get in touch after noticing one or more of the following:

  • Seals disturbed by maintenance and left open
  • Improvised or mixed-product fire seals
  • Unsealed openings around new pipes and cables
  • Old intumescent sealant that has split away

Where a unit on an estate such as New Barn Industrial Park, 1.7 miles north-east of Rookley Green, has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail.

What your quote should include

  • How the joint faces will be prepared and primed
  • Whether old or failed sealant will be cut out, not overlaid
  • Who will actually carry out the work
  • How long is the guarantee, and what does it include?

How to choose a sealant contractor

How the quote is worked out

Each job is priced on its own details. The main factors are:

  • Location, for remote and island sites
  • Any access equipment needed
  • Specialist products, such as fire-rated or hygienic sealants
  • Whether the work must be split into stages

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we will put a fixed figure on it.

Before you send an enquiry

The more we know, the firmer the quote. When you get in touch, include:

  • Anything awkward about access or site hours
  • Asbestos survey details if the building is older
  • Drawings or a marked-up plan, if available
  • Any dates the work must fit around

Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. To get it moving, speak to us on 01277 525 020 or email a schedule or drawings.

Site staff or a sealant specialist?

Redoing a failed joint normally costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

Diagnose, treat, sign off

We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Rural sites near Rookley Green may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.

  1. First we go through the drawings, schedule or specification for the seals and raise any questions before we price.
  2. On site, each opening is checked against the tested detail it is meant to follow.
  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. We apply the specified sealant to the depth and around the services as the detail shows.
  6. Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.

What we need from you

  • Send your site hours and access windows
  • For older buildings, check the asbestos register before work
  • Move anything stored against the joints

Quotes

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. For smaller jobs, photos and a description will do.
