Fire stopping across Hollybushes

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

Fire stopping for commercial buildings in Hollybushes

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. Site teams most often ask us about penetration schedules that need working through and fire-rated sealant that has cracked or shrunk back, across small duct penetrations where the tested detail allows, joints between fire-resisting walls and floors and service gaps in risers. Whoever orders the work in Hollybushes, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.

A job near Hollybushes is typically planned around one visit, with the specification and photos sent in advance. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

What sets the cost

We price every job individually. The main factors are:

  • Any access equipment needed
  • Specialist products, such as fire-rated or hygienic sealants
  • The size and state of each joint
  • Removal of failed or old sealant

Pricing service penetrations depends on quantities, condition and access, and any specification that applies. Call for a quote.

Sending details for a quote

To price the job accurately, we need to understand the site. Useful things to include:

  • The postcode of the building
  • Photos of the joints, close up and from further back
  • Your programme or deadline
  • The asbestos register, for older buildings

To get a fixed quote, call the office on 01277 525 020 or email us with the site address and an outline of the work. Our quote form is another easy route.

Owners, agents and contractors

Whether you’re 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.

For main contractors, we work as the sealant subcontractor. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.

Where services cross fire walls in Hollybushes

Hollybushes is about 39 miles from central London. Office refits around the commuter belt bring new cabling through fire-resisting walls; the gaps need the specified seal. For England, the fire stopping of penetrations is dealt with in Approved Document B. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. What we install is set by the specification, and it goes in to the tested detail.

For a school such as Milstead and Frinsted Church of England Primary School, penetration sealing fits best at the end of the summer works. In a building such as Church of St Mary and the Holy Cross, any service penetration through a fire-resisting wall should be sealed to the specified detail. Tenant changes at parks like Kent Science Park, 1.8 miles north of Hollybushes, bring new data and services, and openings through fire-resisting walls need the specified seal.

Hollybushes is about 4 miles south of Sittingbourne, in Kent. Across the ME9 postcode area, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. 931 places across Kent fall within our area, including Hollybushes. Our London page has more on work in that area (39 miles or so).

Maintenance after handover

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

  • Arrange inspection before areas are covered up
  • Make fire stopping part of every scope that crosses a fire-resisting wall
  • Ask which product is in place before decorating
  • Settle who seals which penetrations at the start of a project

Store the specified product details somewhere the next contractor can find them. It makes later repairs much easier to match.

On fit-outs, get the fire-stopping specification agreed before the services go in. Details can then be picked to suit the actual pipes, cables and ducts.

General trades versus a specialist

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

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.

Questions about Hollybushes

How does the removal of BS 476 from Approved Document B affect fire-rated sealing in Hollybushes?

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 at a site such as Kent Science Park, by Hollybushes?

Yes, sites like Kent Science Park are within our area, along with the rest of Hollybushes. Send details of the unit and the work through our quote form for a quick quote.

Do you have public liability insurance?

Yes. Our insurance certificate can be sent alongside the quote.

Which sealant will you use?

The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

How soon can the area be used again?

The product and site conditions decide that. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.

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.

Can you follow the specification on our project?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.

On site: what to expect

Tell us your site hours and access windows and we’ll plan around them. While we are working, the area stays contained and tidy, and your contact hears from us before we move to the next area.
