Fire stopping across Wolverton

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

How we handle fire stopping in Wolverton

The test standards are BS EN 1366-3 for penetration seals and BS EN 1366-4 for linear joints, with results classified under BS EN 13501-2. A rating such as EI 60 only holds when the product is installed as it was tested. So our job is to reproduce that arrangement faithfully. If you are dealing with builders’ foam or ordinary silicone in compartment walls and fire-rated sealant that has cracked or shrunk back, we can put it right, on small duct penetrations where the tested detail allows, cable penetrations and linear gaps at wall heads alike. Looking for mastic applicators who cover Wolverton? We’ve been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.

For a smaller site near Wolverton, we plan to do all the penetrations in one go, with the specification and photographs sent in advance. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.

Our 12-month guarantee is about workmanship, not 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.

Do you need fire stopping in Wolverton?

Linear gaps fail where a fire-resisting wall meets a slab, soffit or another wall. Movement in the frame or slab can open the joint. The tested detail for a linear joint states the width and movement it covers.

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

  • Seals that don’t match their tested detail
  • Unsealed penetrations discovered above suspended ceilings
  • Fire-stopping items raised at inspection or handover
  • Unsealed joints where partitions meet the slab

Hotels like The George & Dragon Country Pub & Hotel (to the east of Wolverton) are refurbished in phases, and each phase can open up compartment walls.

Where services cross fire walls in Wolverton

A number of hotels sit less than 2 miles from Wolverton. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close. Wolverton lies roughly 49 miles out from central London. Office refits around the commuter belt bring new cabling through fire-resisting walls.

Theatres, wards and plant rooms at sites like Park Prewett Hospital (4.9 miles south-east of Wolverton) all have compartment walls crossed by services. In a building such as Church of St Catherine, any service penetration through a fire-resisting wall should be sealed to the specified detail.

Wolverton: questions and answers

What does the BS 476 change mean for fire-rated sealant in Wolverton?

Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.

Can you work on a hospital site such as Park Prewett Hospital?

Yes, healthcare and care buildings are part of our work. We follow the site’s permits, sign-in and infection-control procedures in every area.

How long will the new sealant last?

There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.

How do I request a quote?

It works in four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photos and a postcode.

What do you charge?

We don’t publish prices, because every site is different. With photos or drawings, we can give you a fixed quote.

Do you guarantee your work?

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

Can you fit around our working hours?

We’re in the office from 8am until 5pm, Monday to Friday. Let us know your site hours and access windows, and the work will be planned around them.

How the job changes by surface

Risers and ceiling voids

Voids hide a lot of unsealed openings. We work through the areas on your schedule methodically.

Masonry and concrete

Block walls and concrete floors are common substrates for penetration seals. Dust and loose debris are cleared out of the opening, with backing added if the detail requires it.

Cost factors for service penetrations

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

  • Location, for remote and island sites
  • Phasing around occupants
  • Access and working height
  • The site’s rules and procedures

Pricing service penetrations depends on how many there are, their condition and the access. Call for a quote.

Sending details for a quote

To price the job accurately, we need to understand the site. Send us:

  • Photos of the joints, close up and from further back
  • Any specification or named product
  • The site address and postcode
  • Access details, including height

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.

Work for main contractors and building owners

Whether you are a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.

When you manage a building on behalf of an owner, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.

Diagnose, treat, sign off

Site rules come first: signing in, inductions and any permit to work. With the paperwork done, the joints are worked through in the order agreed with your site contact. For work around Wolverton, we aim to finish in one visit, so we ask for photos and rough sizes first. That way the right products come on the day.

  1. First we go through the drawings, schedule or specification for the seals.
  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. We fit the backing the detail asks for, to the stated depth.
  5. Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
  6. If an opening needs something other than sealant, we tell you instead of improvising.

Before we start on site

  • Explain the parking and delivery arrangements
  • Send asbestos survey details if the building is pre-2000
  • Let us know about inductions and permits

Advice

Should maintenance staff do it?

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

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.
