Cost factors for service penetrations

The price varies from site to site. Expect it to depend on:

  • Removal of failed or old sealant
  • Whether the work must be split into stages
  • Location, for remote and island sites
  • The product specified

Pricing service penetrations depends on quantities, condition and access, plus any specification you’re working to. Ask us for a fixed quote.

Details that help us quote

For an accurate fixed quote, we need a clear picture of the site. Send us:

  • The postcode of the building
  • Whether the building will be occupied during the work
  • Specification clauses that apply
  • Clear photographs of the problem areas

About our fire stopping in Fullwell Cross

On a fit-out or refurbishment, we follow the services contractors floor by floor. We work from your penetration schedule or marked-up drawings and the specified product data. Tell us what records you need and we’ll confirm with the quote. Most enquiries involve service penetrations left open after M&E works and fire seals cut back for extra cables and never reinstated, across small duct penetrations where the tested detail allows, service gaps in risers and pipe penetrations. A single leaking joint is often how a building in Fullwell Cross first comes to us: we look at the rest while we are there and tell you what we find.

In a London area such as Fullwell Cross, buildings are refitted often, and every new cable, pipe or duct through a fire-resisting wall or floor leaves a gap. Each service penetration gets fire-rated or intumescent sealant if that’s what is specified, laid to the product’s tested arrangement.

The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Compartment walls and floors in Fullwell Cross

With tenants changing and fit-outs following, London buildings see service routes altered again and again. We seal to the specification and the product’s tested detail, working within the building’s permits. Approved Document B is the English guidance that covers fire stopping around openings and penetrations. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. Our part stays the same: the specified product, installed to its tested detail.

In a hotel such as London Chigwell Prince Regent Hotel, which lies north-west of Fullwell Cross, new pipework or cabling through bedroom and corridor walls needs sealing with the specified product. Wherever services are added at a hospital such as King George Hospital (1.6 miles south-east of Fullwell Cross) the compartment line has to be made good with the specified product.

Fullwell Cross is about 2 miles east of Woodford, in Greater London. Anywhere in IG6, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Fullwell Cross is one of 764 places in Greater London on our list. For work in that direction, see our London page, about 10 miles away.

How the job changes by surface

Metal pipes

Copper and steel pipes are a common service penetration for fire-rated sealant. Pipe diameter, annular gap, sealant depth and any pipe insulation all have to match the detail and we confirm each before sealing.

Risers and ceiling voids

Openings above suspended ceilings are easy to miss. We work through the areas on your schedule methodically and tell you about openings outside the list.

When something else is needed

Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be any of the following:

  • Fire risk assessments, a job for a competent assessor
  • Walls or floors that aren’t fire-resisting to begin with
  • Openings that need collars, wraps, batts or boards rather than sealant

If you’re not sure, just call the office on 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
  • Pipe penetrations
  • Joints between fire-resisting walls and floors
  • Linear gaps at wall heads
  • Service gaps in risers
  • Small duct penetrations where the tested detail allows

How a job runs

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. In Fullwell Cross, most buildings stay in use during the work, so we agree zones and timings with the building or facilities manager. Phased work keeps the rest of the building in use.

  1. The specification and schedule come first, so we know which details apply.
  2. Access, permits and the order of areas are agreed with the site team.
  3. Each opening is checked for wall or floor type, service, gap and depth.
  4. Foam, ordinary sealant and debris come out first.
  5. The specified backing and sealant go in to depth and are finished neatly.
  6. Anything outside the detail is reported to you rather than sealed.

Before we start on site

  • Flag any permit to work we’ll need
  • Share the asbestos register for older buildings
  • Explain the parking and delivery arrangements

Advice

Your questions answered

Is Newbury Retail Park, near Fullwell Cross, within your area?

Yes. Our area takes in Fullwell Cross and its surroundings, with estates and business parks such as Newbury Retail Park included. A few photos and the unit address let us price the work.

Do you seal service penetrations in hotels around Fullwell Cross?

Yes, where the specification calls for fire-rated sealant. It goes in to the manufacturer’s tested detail for the wall or floor and the services passing through, and we’ll tell you if the detail calls for a collar, wrap or batt instead.

Do you seal on top of existing sealant?

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

Can you quote from photos?

Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we’ll arrange a visit before quoting.

Will you quote for a small job?

Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.

Do you take on multi-site work?

Yes. A group of buildings can go on one quote, with one point of contact across South East England, Greater London and Scotland.

Do you cover Fullwell Cross?

Yes. We take on work across Fullwell Cross, and the same phone number covers every area.

Keeping the joints sound

Cleaning and maintenance staff play a part too. Share these points with them:

  • Ask the designer to confirm details early on refits
  • Don’t let anyone top up a fire seal with the wrong product
  • Leave fire sealant to cure fully before covering it
  • Check risers and ceiling voids after each round of works

After every round of M&E works, check that the openings created have been sealed. A short check at the end of each job saves a long hunt later.

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.

Signs you need fire stopping in Fullwell Cross

Most open service penetrations are left by later work. New cabling, rerouted pipework or a data route drilled through a riser leaves an opening that nobody returns to. Across several fit-outs, the openings add up.

These are often picked up first by site or facilities staff:

  • Damaged fire seals in risers and voids
  • Openings found when ceilings come down for a refit
  • Expanding foam used as fire stopping
  • Improvised or mixed-product fire seals

Residences at universities like University of Portsmouth Walthamstow Campus, 4.4 miles to the west of Fullwell Cross, have compartment walls that must be resealed whenever services change.

Questions to ask before you book

  • Will RAMS and insurance details be available?
  • Their public liability cover
  • Do they follow the manufacturer’s priming guidance?
  • Are they CHAS accredited or on Constructionline?
