Fire stopping for Rookley sites

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

From enquiry to sign-off

A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself normally 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. Rural sites near Rookley may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.

  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. If an opening needs something other than sealant, we tell you instead of improvising.

What we need from you

  • Share the asbestos register for older buildings
  • Have the specification and drawings to hand
  • Let building users know which areas are affected

Fire stopping for commercial buildings in Rookley

No fire sealant works on its own: its test evidence covers one product in one kind of wall or floor, with set services, gaps, depths and backing. Before we seal anything, we check the opening against the detail it is meant to follow. We work on cable penetrations, pipe penetrations and small duct penetrations where the tested detail allows, and what we’re called in for most is seals that don’t match their tested detail and fire-stopping items raised at inspection or handover. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Rookley it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Smaller places such as Rookley still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.

Whoever the client is, the cover is the same: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Aftercare for building managers

A few simple habits keep the new joints working:

  • Leave fire sealant to cure fully before covering it
  • Keep product data and details in the fire safety file
  • Look above ceilings when tiles are lifted for other jobs
  • Report damaged or disturbed seals as soon as they’re spotted

After every round of M&E works, check that the openings created have been sealed. Building it into each contractor’s sign-off keeps the walls intact.

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

What we can’t put right

Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. It won’t fix:

  • Openings that need collars, wraps, batts or boards rather than sealant
  • Reviewing a building’s overall fire safety
  • Walls or floors that aren’t fire-resisting to begin with

If you’re not sure, just call 01277 525 020 or send details through our quote form and we will give you a straight answer.

Joints and surfaces we work on

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

What affects the price in Rookley

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

  • Distance, for remote addresses
  • The total length or number of joints
  • Induction, permit and paperwork requirements
  • Whether the work must be split into stages

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote.

What to include in your enquiry

A few photos plus some basic facts will normally do. It helps to include:

  • Where the site is, with the postcode
  • When you need the work done
  • How the joints are reached, and at what height
  • Rough lengths or quantities, or drawings if you have them

Need a figure for a tender or a budget? Send the scope and any drawings, and we will return a fixed quote you can plan around. For a chat about it beforehand, phone 01277 525 020 or send photos by email.

Compartments and services around Rookley

Approved Document B is the English guidance that covers fire stopping around openings and penetrations. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. Either way, we install the specified product to its tested detail.

Wherever services are added at a hospital such as Whitecroft Hospital, 1.6 miles north-west of Rookley, the compartment line has to be made good with the specified product. For a school such as Chillerton and Rookley Primary School, penetration sealing fits best at the end of the summer works. On estates like New Barn Industrial Park, which lies north-east of Rookley, the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal.

Rookley is about 3 miles south of Newport, in the Isle of Wight. We cover Rookley and the rest of the Isle of Wight, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. 125 places across the Isle of Wight fall within our area, Rookley among them. Portsmouth is covered too, some 14 miles away.

If you need fire stopping in PO38, the process matches everywhere else we work: send details, get a quote, we seal, guaranteed. Among the streets we cover are Manor Crescent, Niton Road and Main Road, and sites on any of them can send details for a fixed quote. We also cover Rookley Green (1 mile south), Merstone (1 mile north-east), Blackwater (1 mile north), Godshill (2 miles south-east) and Sandford (2 miles south-east). A short drive away, we cover Newport (3 miles north), Ryde (7 miles north-east), Cowes (7 miles north), Sandown (5 miles east), Shanklin (5 miles east) and Ventnor (5 miles south-east). Island and remote sites need extra planning, with travel, ferry crossings where needed and weather to allow for, so give the site location in your enquiry.

Local landmarks in Rookley

We work on buildings around Chequers Inn and the streets around them. The closest station to Rookley is Shanklin station, about 4.7 miles east of the centre. A little further out are Carisbrooke Castle (2.7 miles north-west) and Whitecroft Hospital (1.6 miles north-west). For a walk, there’s Stenbury Down and Alverstone Mead.

Rookley: questions and answers

What happens to BS 476 references for fire stopping in Rookley?

References to BS 476 classes are being removed from Approved Document B from 2 September 2029, after which BS EN 13501-2 classification is the route, subject to transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.

Is Rookley too small for you to travel to?

No. Small places get the same service as large ones. London and every South East county are within our area. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.

Can weather delay the job?

It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

Which sealant will you use?

Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Will your applicators have CSCS cards?

Yes. Should the site need card details in advance, tell us and we’ll confirm them with the quote.

Do you seal on top of existing sealant?

No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.

Can you work while the building is occupied?

Yes, as long as we plan it. Tell us your site hours and access windows and we’ll plan around them.

How the job changes by surface

Small ducts

Some fire-rated sealant details cover small ducts. Bigger ducts and fire-resisting ductwork are normally handled with other products and we flag that rather than guess.

Masonry and concrete

Core-drilled holes are neat; broken-out ones rarely are. Each gap is measured where it is widest so we know it sits within the tested range, and any that don’t are flagged.

Work for main contractors and building owners

Whether you’re a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.

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