Fire stopping in Dibden Purlieu

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

Doing it in-house

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

Fire stopping in Dibden Purlieu

Fire-rated sealant suits many small service penetrations: copper and steel pipes, cables and some small ducts where the tested detail allows. Larger openings and some plastic pipes call for collars, wraps, batts or boards instead. If the detail calls for something other than sealant, we say so rather than force sealant into it. Most enquiries involve penetration schedules that need working through and fire sealant pulled out of the opening, on small duct penetrations where the tested detail allows, pipe penetrations and linear gaps at wall heads. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Dibden Purlieu, that means joint design, primers and backing rod as standard.

Around smaller places like Dibden Purlieu, many commercial buildings are conversions or extensions of older ones, so it’s worth confirming the wall or floor type before choosing the seal. The right product depends on the wall or floor and the services passing through, and we will tell you if the detail calls for something other than sealant.

Every job is signed off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

What sealant work can’t fix

We check first that sealant really is the fix. It won’t put right:

  • Designing or specifying fire stopping, which sits with the designer or fire engineer
  • Gaps in walls that were never built as compartment walls
  • Fire risk assessments, a job for a competent assessor

Not sure which it is? You can call 01277 525 020 or use the quote form and we’ll tell you honestly before you book.

What we seal

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

Penetration seals near Dibden Purlieu

Approved Document B is the English guidance that covers fire stopping around openings and penetrations. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. Our part stays the same: the specified product, installed to its tested detail.

In a hotel such as Fountain Court Hotel, which lies east of Dibden Purlieu, new pipework or cabling through bedroom and corridor walls needs sealing with the specified product. At a university such as Southampton Solent University, 3.7 miles to the north of Dibden Purlieu, labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work. At a healthcare site like Hythe Hospital, which lies north-east of Dibden Purlieu, new services through compartment walls are a constant, and each needs the specified seal.

Dibden Purlieu is about 4 miles south of Southampton, in Hampshire. Our applicators travel to Dibden Purlieu for work on service penetrations, handled exactly as we handle every other area. Our Hampshire coverage takes in 723 places, from busy centres to rural villages.

How the quote is worked out

Sealant work doesn’t have a standard rate, since sites vary so much. What we take into account:

  • The size and state of each joint
  • Which sealant the job calls for
  • Distance, for remote addresses
  • Site requirements such as inductions and permits

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

What we need to price the job

A good diagnosis starts with the right details. Let us know:

  • The postcode of the building
  • Specification clauses that apply
  • Access details, including height
  • Approximate linear metres or a joint schedule

Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to give us a call on 01277 525 020 or send photos by email with what you know.

Leave it or put it right?

Fire stopping is a regular point raised at inspections and handover. Finding unsealed or improvised openings late can hold up a programme. Small buildings around Dibden Purlieu suffer from failed joints as much as large ones. Early resealing avoids the damage that follows a leak.

There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote.

Why us?

  • Specification-led, product-correct work
  • Our applicators hold CSCS cards
  • A fixed quote before work starts
  • Joints cleaned back to sound surfaces

Keeping the joints sound

Your facilities or cleaning team can help the joints last. Pass these on to them:

  • Agree the fire-stopping specification before services go in
  • Report damaged or disturbed seals as soon as they’re spotted
  • Keep product data and details in the fire safety file
  • Include service cupboards in routine inspections

Don’t patch a fire-rated seal with anything outside its tested detail. Repairs need the same product and detail as the original, or a new specification from the designer.

Looking at service areas on a regular cycle pays off. Catching a damaged seal early keeps the fix small; found late, it can be one of many.

Common questions from Dibden Purlieu clients

Would you work within a site like Hythe Hospital?

Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

How does the move away from BS 476 affect penetration seals in Dibden Purlieu?

From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.

Are you CHAS accredited?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

How do I request a quote?

There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photos and a postcode.

Can you work while the building is occupied?

Yes, with some planning. Tell us your site hours and access windows and we’ll plan around them.

Can one quote cover more than one building?

Yes. Several buildings can share a single quote, and you deal with one contact throughout across South East England, Greater London and Scotland.

Do you guarantee your work?

Yes, for 12 months. If our installation fails in that time, we return and fix it.

Diagnose, treat, sign off

Occupied buildings need a little choreography. We sign and contain the area we are in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. For a job in Dibden Purlieu, the main thing is a clear picture of the work, so send photos of each area. You’ll then get a fixed price for the work.

  1. We start with your penetration schedule, drawings or specification.
  2. We plan the sequence of floors, risers and voids with you.
  3. We compare every service penetration with its tested detail before sealing.
  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.

Getting the site ready

  • Make sure the joints can be reached
  • Let building users know which areas are affected
  • Agree which areas must stay open

Getting a fixed quote

Let us know the site, the scope and your timescale, and a fixed quote will follow. The easiest way is to phone 01277 525 020 or email the details over.
