Fire stopping for businesses in Maidstone

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

Fire stopping in Maidstone

Sealant is the specified answer for plenty of openings, such as metal pipes, cables and some small ducts where the detail covers them. Larger openings and some plastic pipes call for collars, wraps, batts or boards instead. If the detail calls for something other than sealant, we say so rather than force sealant into it. If you have damaged fire seals in risers and voids and unsealed penetrations discovered above suspended ceilings, we can put it right, on cable penetrations, linear gaps at wall heads and service gaps in risers alike. Looking for mastic applicators who cover Maidstone? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.

Places the size of Maidstone typically have healthcare, education and commercial buildings divided into fire compartments. Every pipe, cable or duct through those walls and floors needs a seal that matches its tested detail.

A 12-month guarantee applies to all our work. Should something we installed fail, call the office on 01277 525 020 or send photos by email and we will come back to it.

Surface by surface

Small ducts

Some fire-rated sealant details cover small ducts. Bigger ducts and fire-resisting ductwork are normally handled with other products and we flag that rather than guess.

Cables and cable bundles

Cable penetrations are frequently sealed with fire-rated sealant where the detail allows. Bundle size, cable type and the space between cables all matter and we work within those limits.

How the quote is worked out

Quotes vary with the job. It mainly depends on:

  • Phasing around occupants
  • Induction, permit and paperwork requirements
  • Access and working height
  • Joint width, depth and condition

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we’ll explain how it’s made up.

Sending details for a quote

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

  • Rough lengths or quantities, or drawings if you have them
  • Any dates the work must fit around
  • Anything awkward about access or site hours
  • Whether an asbestos survey exists

Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we’ll arrange a site visit if anything is unclear.

What sealant work can’t fix

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

  • Plastic pipes whose detail calls for a collar or wrap
  • Designing or specifying fire stopping, which sits with the designer or fire engineer
  • Gaps in walls that were never built as compartment walls

If in doubt, call 01277 525 020 or email drawings and photos and we will say what we think before you book.

Where we work in Maidstone

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

From enquiry to sign-off

Working in a building that stays open takes some planning. We sign and contain the area we are in, keep walkways clear and work section by section so the rest of the building stays in use. Sites in a big town such as Maidstone frequently have reception sign-in, inductions and permits to work. Tell us about inductions, permits and site hours so the plan fits.

  1. The specification and schedule come first, so we know which details apply.
  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.
  5. The specified backing and sealant go in to depth and are finished neatly.
  6. We tell you about openings that need a different product.

Getting the site ready

  • Send asbestos survey details if the building is pre-2000
  • Send any specification or drawings in advance
  • Warn occupants and staff about the work

Advice

Site staff or a sealant specialist?

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

Building owners, agents and FMs in Maidstone

FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.

We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Sites in Maidstone can sit alongside others in a wider programme.

Maidstone: questions and answers

Is hospital work, at somewhere like The Somerfield Hospital, something you do?

Yes. We work in healthcare settings as well as offices and schools. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Is Tovil Green Business Park, near Maidstone, within your area?

Yes. We cover Maidstone and the area around it, including industrial estates, business parks and retail parks such as Tovil Green Business Park. Photos and a short description are enough for a first look.

Do you cover Maidstone?

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

What will the job cost?

We don’t publish prices, because every site is different. With photos or drawings, we can give you a fixed quote.

How long before the joints can be used?

We’ll confirm how long the chosen product needs to cure, and sign any area that should be left alone.

Is the BS 476 change in 2029 relevant to fire stopping?

For buildings in England, Approved Document B removes BS 476 references from 2 September 2029. Products are then judged on BS EN 13501-2 classifications, though transitional rules apply. Scotland follows its own Technical Handbook, with clause 2.1.14 covering service penetrations.

Do you need to see the site first?

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

Service penetrations in Maidstone buildings

Maidstone is about 31 miles from central London. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls. Fire stopping of openings and penetrations in England falls under Approved Document B. 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. We install whatever has been specified, to the product’s tested detail.

At a healthcare site like The Somerfield Hospital, 1.1 miles to the north-west of Maidstone, new services through compartment walls are a constant, and each needs the specified seal. Office fit-outs on sites such as Tovil Green Business Park (to the south-west of Maidstone) add cabling and pipework through fire-resisting walls, and fire-rated sealant goes in where the specification calls for it. Colleges such as MidKent College Maidstone Campus, 1.4 miles west of Maidstone, add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product.

Maidstone is about 31 miles south-east of London, in Kent. We cover commercial sites throughout Maidstone, for single jobs and planned programmes alike. 931 places across Kent fall within our area, including Maidstone. For work in that direction, see our London page, about 31 miles away.

Nearby places we also cover include Tovil (1 mile west), Foley Park (1 mile north), Shepway (1 mile south-east), Penenden Heath (1 mile north) and Weavering (1 mile east).
