Fire stopping near Hammerpot

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Building owners, agents and FMs in Hammerpot

Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

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.

How we handle fire stopping in Hammerpot

A fire-rated sealant is only one part of a tested system: the evidence covers a specific product, wall or floor type, service, gap, depth and backing. Before we seal anything, we check the opening against the detail it is meant to follow, and raise it with you if it falls outside. If you have improvised or mixed-product fire seals and unsealed penetrations discovered above suspended ceilings, we can put it right. Most enquiries from Hammerpot start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Smaller places such as Hammerpot 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.

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.

Cost factors for service penetrations

To price the job, we consider:

  • How much existing material needs removing
  • Phasing around occupants
  • How accessible the joints are
  • Quantities, in metres or numbers

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

What we need to price the job

It doesn’t need to be a full survey. A few details are enough to get going:

  • Whether an asbestos survey exists
  • Approximate linear metres or a joint schedule
  • Clear photos of the problem areas
  • Specification clauses that apply

Let us know the site, the scope and your timescale, and we will put a fixed quote together. The easiest way is to call the office on 01277 525 020 or email us.

Should maintenance staff do it?

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

What sealant work can’t fix

Not every problem is a sealant problem, and we’d rather tell you before you spend money. It won’t fix:

  • Issuing fire ratings or certificates for seals
  • Large openings beyond what any sealant detail covers
  • Designing or specifying fire stopping, which sits with the designer or fire engineer

If you are not sure, just speak to us on 01277 525 020 or send photos by email and we’ll give you a straight answer.

Joints and surfaces we work on

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

From enquiry to sign-off

On arrival, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before any cutting starts, with the work itself normally taking a single visit for a short list of penetrations, or a phased programme for a whole building. Jobs in and around smaller places like Hammerpot are typically planned as a single visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.

  1. First we confirm the product and tested details named in the specification.
  2. We sort the openings by the detail each one needs.
  3. Improvised fillers and failed sealant are removed.
  4. Where the detail needs backing, it goes in at the stated depth.
  5. We gun the sealant in to the specified depth around each service and tool it.
  6. Completed areas are checked with you, with the records agreed when we quoted.

Getting the site ready

  • Send any specification or drawings in advance
  • Make sure the joints can be reached
  • Explain the parking and delivery arrangements

Advice

Fire-rated sealing for Hammerpot buildings

Hammerpot has three care or nursing homes no more than 2 miles away. In a care home, any new pipe or cable through a fire-resisting wall should be sealed to the specified detail. At about 49 miles from central London, Hammerpot is within reach of the capital. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls, and the gaps need sealing with the specified product.

Holiday works at schools like St Margaret's CofE Primary School often leave service openings to seal before pupils return. On estates like The Vinery Industrial Estate (0.9 miles west of Hammerpot), the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal.

Hammerpot: questions and answers

Is hospital work, at somewhere like Zachary Merton Hospital, something you do?

Yes, healthcare and care buildings are part of our work. Work is phased so departments keep running, under the site’s own rules.

Do you work in occupied care homes around Hammerpot?

Yes. Care settings are planned area by area, at times agreed with the home. Tell us about any infection-control or safeguarding requirements and we will work to them.

Is colour matching possible?

Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We’ll confirm the colours available for the specified product.

Do you hold third-party fire-stopping installer certification?

No. We don’t hold a third-party fire-stopping installer certificate. We are CHAS accredited and a Constructionline member, and our applicators are CSCS-carded. If your contract requires third-party installer certification, we’re not the right fit for that package.

Do you take on multi-site work?

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

Will you just go over the old sealant?

No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.

Do you work in Hammerpot?

Yes. Sites across Hammerpot are covered, with one number for every area we cover.

Do you need fire stopping in Hammerpot?

Head-of-wall joints and wall-to-wall junctions are frequent weak points. Movement in the frame or slab can open the joint, and a product not tested for that movement may crack. Linear joint details set a width range and movement capability, and the seal has to sit within them.

Typical triggers for a call:

  • Fire-rated sealant that has cracked or shrunk back
  • Seals that don’t match their tested detail
  • Head-of-wall gaps with no fire seal
  • Snag lists that include open service penetrations

In a hotel such as Angmering Manor Hotel, 0.9 miles south of Hammerpot, new pipework or cabling through bedroom and corridor walls needs sealing with the specified product.

What your quote should include

  • Their pre-qualification and accreditations
  • Whether their applicators hold CSCS cards
  • How the existing material will be dealt with
  • Is the sealant right for the movement and the substrate?
