Questions about Gillingham

Will you take on work at estates like Gillingham Business Park, close to Gillingham?

Yes, sites like Gillingham Business Park are within our area, along with the rest of Gillingham. A few photographs and the unit address let us price the work.

Will you work in a care home in Gillingham without moving residents out?

Yes. Care settings are planned area by area, at times agreed with the home. We follow the home’s own procedures throughout.

Can you quote from photographs?

Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit before quoting.

How do we ask for a quote?

There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photographs and a postcode.

How soon can the area be used again?

That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.

How long does a job like this take?

We plan the time on site around your programme and access. We’ll give you an estimate of time on site when we quote.

What does an EI 60 rating mean?

Penetration seals are tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4. Results are classified under BS EN 13501-2 as E for integrity and I for insulation, with a time such as EI 60 or EI 120. The rating applies to the product as tested.

Fire stopping in Gillingham

Every service that crosses a compartment wall or floor leaves an opening, and that opening needs sealing to hold back fire and smoke. 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. If you are dealing with damaged fire seals in risers and voids and fire-stopping items raised at inspection or handover, we can help, on joints between fire-resisting walls and floors, pipe penetrations and linear gaps at wall heads alike. Looking for mastic applicators who cover Gillingham? We have been sealing commercial buildings since 2005, with CSCS-carded applicators.

On larger sites around Gillingham, fire-rated sealing normally follows the M&E trades floor by floor. Design and sign-off of fire stopping rest with the designer, fire engineer or building control; we install what has been specified.

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.

On site: what to expect

Tell us your site hours and access windows and we will plan around them. While we’re working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. Town-centre jobs in Gillingham can mean limited parking and loading, while out-of-town estates typically have yards and car parks. Either way, tell us what’s available.

  1. We start with your penetration schedule, drawings or specification.
  2. Access, permits and the order of areas are agreed with the site team.
  3. We compare every service penetration with its tested detail before sealing.
  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.

Preparing the site

  • Move anything stored against the joints
  • Point out parking and an unloading spot
  • Confirm the product named in the specification

Where services cross fire walls in Gillingham

At about 30 miles from central London, Gillingham is within reach of the capital. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls. The 2 miles around Gillingham include seven care or nursing homes. Care settings depend on compartmentation, so service penetrations made during maintenance or refurbishment need sealing with the specified product.

For a site team at a college like MidKent College Gillingham Campus, 2.1 miles north-west of Gillingham, fire-rated sealing is best scheduled after the summer works. Tenant changes at centres like Parkwood Shopping Centre (1.8 miles south-east of Gillingham) often mean new services through walls between units.

Gillingham is about 30 miles east of London, in Medway. Our applicators travel to Gillingham for work on service penetrations, handled exactly as we handle every other area. Gillingham is one of 54 places in Medway on our list for service penetrations. Sites around London have their own page, roughly 30 miles from Gillingham.

Work on service penetrations is covered throughout ME8, ME7, ME4 and ME5. Streets here include Leeds Square, London Road and Dorset Square. Main routes into Gillingham include the A2 and A231. If your building is just outside Gillingham, we cover Twydall (1 mile east), Lower Twydall (1 mile north-east), Grange (1 mile north), Darland (1 mile south-west) and Hale (1 mile south-west). Bigger towns within reach include Rochester (4 miles west), Strood (4 miles west), Lordswood (3 miles south-west), Hoo St Werburgh (4 miles north), Rochester Riverside (3 miles north-west) and Frindsbury (4 miles north-west).

Leave it or put it right?

An open or wrongly sealed service penetration lets fire and smoke reach the next compartment much sooner than the building was designed for. Putting it right is usually a modest job when the openings are accessible. Left until ceilings are closed or a tenant moves in, the same work costs more access and more disruption. Businesses in Gillingham often have several buildings with joints of a similar age. Dealing with them together saves repeat visits.

The specified product makes a difference, as does the preparation each joint needs. Access, phasing and site requirements come into it too.

Honest limits

Some faults sit outside our scope, and we point that out rather than sealing over them:

  • Walls or floors that aren’t fire-resisting to begin with
  • Plastic pipes whose detail calls for a collar or wrap
  • Fire risk assessments, a job for a competent assessor

If in doubt, speak to us on 01277 525 020 or email us and we’ll say what we think.

Where we work in Gillingham

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

Common problems we fix in Gillingham

On a busy project, programme pressure can mean fire stopping is rushed or left to whichever trade is closest. That is how unsuitable products and improvised details end up in compartment walls.

Site and facilities staff are often the first to spot these:

  • Unsealed openings around new pipes and cables
  • Unsealed joints where partitions meet the slab
  • Snag lists that include open service penetrations
  • Old intumescent sealant that has split away

For a hospital such as Medway Maritime Hospital, 1.6 miles west of Gillingham, penetration sealing is usually phased ward by ward, with infection-control rules agreed first.

Questions to ask before you book

  • Whether old or failed sealant will be cut out, not overlaid
  • The named product and why it was chosen
  • What site paperwork they can supply
  • How they’ll work around occupants

Choosing a commercial sealant contractor

Quoting for work in Gillingham

We price every job individually. The things that drive the figure:

  • Whether the work must be split into stages
  • Access and working height
  • Joint width, depth and condition
  • Location, for remote and island sites

There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote and we will price your job on its own details.

What to include in your enquiry

To price the job accurately, we need a clear picture of the site. Send us:

  • Access details, including height
  • Whether an asbestos survey exists
  • Approximate linear metres or a joint schedule
  • The type of building and who uses it

Send details, get a quote, we seal, guaranteed: that’s how every job runs. To take the first step, give us a call on 01277 525 020 or email drawings and photos.

When to bring in a specialist

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.

Redoing a failed joint usually costs more than getting it right at the outset, 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.
