Why act early in Lordswood

The longer openings stay, the more there tend to be: every new cable or pipe adds another. Keeping on top of it after each round of works keeps the job small and avoids a much larger catch-up later. Sealant hardens, cracks and loses grip with age, UV and movement. Renewing it in good time keeps the building weathertight.

A quote for service penetrations depends on how many there are, their condition and the access, plus any specification you are working to. Ask us for a fixed quote.

About our fire stopping in Lordswood

Where pipes, cables and other services cross a compartment wall or floor, the opening around them has to be closed so fire and smoke can’t move between compartments. Our part is installing fire-rated and intumescent sealant at those openings and along linear gaps, where the specification calls for it. We work to the product’s tested detail for every seal, not a rule of thumb. We work on service gaps in risers, linear gaps at wall heads and small duct penetrations where the tested detail allows, and what we’re called in for most is service penetrations left open after M&E works and head-of-wall gaps with no fire seal. Whoever orders the work in Lordswood, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.

Fire-rated sealing in a place like Lordswood is normally a single building at a time. With the specification and photographs of the gaps, we can give a fixed quote and bring the right products.

A 12-month guarantee applies to all our work in Medway. Should something we installed fail, call 01277 525 020 or use the quote form and we will come back to it.

On site: what to expect

When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before any cutting starts, and the work typically takes a single visit for a short list of penetrations, or a phased programme for a whole building. What matters most for a job in Lordswood is a clear list of what needs doing. You will then get a fixed price for the work.

  1. The specification and schedule come first, so we know which details apply.
  2. We plan the sequence of floors, risers and voids with you.
  3. Each opening is checked for wall or floor type, service, gap and depth.
  4. Unsuitable material is removed and the opening cleaned 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

  • Move anything stored against the joints
  • Send asbestos survey details if the building is pre-2000
  • Let us know about inductions and permits

Keeping the joints sound

Keep the joints in good shape with a few simple steps:

  • Get seals inspected before ceilings and boxing close
  • Ask which product is in place before decorating
  • Put resealing into every M&E and fit-out package
  • Keep product data and details in the fire safety file

Keep the product data and installation details with the building’s fire safety information. It makes later repairs much easier to match.

A simple record of seal locations and products helps. It tells the next contractor exactly what to reinstate, and it helps at inspections.

Work for main contractors and building owners

For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules.

Whether you are 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. We can agree access arrangements and keyholder contacts beforehand.

What we can’t put right

A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be one of these:

  • Deciding what a wall or floor needs, which belongs to the designer
  • Reviewing a building’s overall fire safety
  • Plastic pipes whose detail calls for a collar or wrap

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

Where we work in Lordswood

Penetration seals near Lordswood

The area within 2 miles of Lordswood holds a number of hotels. Bedroom-to-corridor walls in hotels are normally fire-resisting, so new cabling or pipework through them has to be sealed to the tested detail. In England, Approved Document B covers fire stopping of 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. What we install is set by the specification, and it goes in to the tested detail.

Industrial units on estates such as Lordswood Industrial Estate, 0.5 miles south of Lordswood, often separate offices from warehouse space with fire-resisting walls, and new services through them need the specified seal. Theatres, wards and plant rooms at sites like Spire Alexandra Hospital (0.9 miles south-west of Lordswood) all have compartment walls crossed by services.

Common problems we fix in Lordswood

Openings in fire-resisting walls usually appear when services are added or changed. A new cable pulled by an electrician, a pipe rerouted by a plumber or a data run drilled through a riser can leave the hole behind. Over a few years of fit-outs, a wall can collect a lot of these.

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

  • Openings left by services added after handover
  • Fire sealant pulled out of the opening
  • Non-fire-rated filler around services
  • Snag lists that include open service penetrations

In a school such as St Benedict's Catholic Primary School, fire-rated sealant goes in around service penetrations where it is specified.

Questions about Lordswood

Will you take on work at estates like Lordswood Industrial Estate, close to Lordswood?

Yes. Our area takes in Lordswood and its surroundings, with estates and business parks such as Lordswood Industrial Estate included. To start, just speak to us on 01277 525 020 or send details through our quote form with the unit, the joints involved and your access times.

Is a hospital such as Spire Alexandra Hospital somewhere you can work?

Yes. We work in healthcare settings as well as offices and schools. We follow the site’s permits, sign-in and infection-control procedures in every area.

Is colour matching possible?

Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.

How long will the new sealant last?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

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.

Will you come and look before quoting?

That depends on the size and complexity of the job. Straightforward work can often be priced from photographs and measurements, while larger or less clear jobs get a site visit first.

Do you certify or sign off fire stopping?

No. Sign-off isn’t ours to give, and we don’t hold a third-party installer certificate. We work to the specification and the manufacturer’s installation guidance.
