Fire stopping for Milton-next-Gravesend sites

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

Fire stopping in Milton-next-Gravesend, done properly

Facilities managers in Milton-next-Gravesend often find open service penetrations when ceilings come down for other work. If a specification already covers those walls and floors, we can reseal to it using the product and detail it sets out. Where there isn’t one, the designer or fire engineer needs to set one first. We work on small duct penetrations where the tested detail allows, cable penetrations and linear gaps at wall heads, and what we are called in for most is unsealed penetrations discovered above suspended ceilings and unsealed openings around new pipes and cables. Looking for mastic applicators who cover Milton-next-Gravesend? We have been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.

Fire-rated sealing in a place like Milton-next-Gravesend is typically a single building at a time. Send the specification, drawings or photos of the openings and we’ll quote to suit.

We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

How a job runs

We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. Work in places the size of Milton-next-Gravesend is planned as a single visit where we can. Clear photos and measurements help us bring the right products.

  1. We ask for the product and detail your designer has specified.
  2. Openings are measured and grouped by detail.
  3. Old or wrong materials are cut out.
  4. Where the detail needs backing, it goes in at the stated depth.
  5. Fire-rated or intumescent sealant goes in around the services and is tooled off.
  6. We walk the completed areas with you and confirm the records agreed at quote stage.

Getting the site ready

  • Move anything stored against the joints
  • Arrange parking or a loading space
  • Let building users know which areas are affected

Quotes

Advice

Surface by surface

Small ducts

We seal around ducts only within what the tested detail covers. The ductwork, its supports and any dampers are for the ductwork contractor.

Masonry and concrete

Many seals are made in blockwork, brickwork or concrete slabs. Dust and loose debris are cleared out of the opening.

Do you need fire stopping in Milton-next-Gravesend?

Head-of-wall joints and wall-to-wall junctions are frequent weak points. Movement in the frame or slab can open the joint, and the wrong product can split as a result. Linear joint details set a width range and movement capability, and the seal has to sit within them.

Clients usually get in touch after noticing one or more of the following:

  • Hidden openings found during inspections
  • Non-fire-rated filler around services
  • Service penetrations left open after M&E works
  • Head-of-wall gaps with no fire seal

Wherever services are added at a hospital such as Gravesham Community Hospital, 0.9 miles to the west of Milton-next-Gravesend, the compartment line has to be made good with the specified product.

What your quote should include

  • Are they CHAS accredited or on Constructionline?
  • Their plan for phasing and protecting the area
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • How the joint faces will be prepared and primed

Choosing a commercial sealant contractor

Fire stopping around Milton-next-Gravesend: what changes locally

Central London is about 21 miles from Milton-next-Gravesend. Office refits around the commuter belt bring new cabling through fire-resisting walls, and the gaps need sealing with the specified product. Approved Document B is the English guidance that covers fire stopping around openings and penetrations. 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. We install whatever has been specified, to the product’s tested detail.

For a unit at a site such as Canal Industrial Park, under half a mile north of Milton-next-Gravesend, new power or data runs between office and warehouse can breach a compartment wall. Workshops and IT rooms at colleges like North West Kent College (0.6 miles south-east of Milton-next-Gravesend) are re-serviced often, leaving penetrations to seal.

Milton-next-Gravesend: questions and answers

How does the move away from BS 476 affect penetration seals in Milton-next-Gravesend?

From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.

Is Canal Industrial Park, near Milton-next-Gravesend, within your area?

Yes. We cover Milton-next-Gravesend and the area around it, including industrial estates, business parks and retail parks such as Canal Industrial Park. To start, just phone 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.

Will you just go over the old sealant?

No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.

Which sealant will you use?

If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Will your applicators have CSCS cards?

Yes. Should the site need card details in advance, let us know and we will send them with the quote.

Are you CHAS accredited?

Yes. Mastic Doctor is CHAS accredited and a Constructionline member.

How much does the work cost?

There isn’t a price list, because every site is different. With photographs or drawings, we can give you a fixed quote.

How the quote is worked out

These are the things that shape the price:

  • Quantities, in metres or numbers
  • Backing rod, priming and other preparation
  • Phasing around occupants
  • Induction, permit and paperwork requirements

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

Before you send an enquiry

Diagnosis starts before we arrive. Let us know:

  • The postcode of the building
  • Approximate linear metres or a joint schedule
  • Any specification or named product
  • Whether an asbestos survey exists

The quickest route to a quote is a few photos and the site postcode. Send them through the quote form, or give us a call on 01277 525 020 or email drawings and photos if you’d rather talk the job through.

Why act early in Milton-next-Gravesend

An improvised seal can look finished while offering no tested performance. Correcting it means cutting it out and starting again with the specified product. In a smaller place such as Milton-next-Gravesend, getting a contractor back for a second visit takes time, so it’s worth dealing with every failing joint at once.

The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.
