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

How we handle fire stopping in Garlinge Green

Facilities managers in Garlinge Green 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. With no specification in place, the first step sits with your designer or fire engineer, not with us. Most enquiries involve improvised or mixed-product fire seals and unsealed openings around new pipes and cables, across small duct penetrations where the tested detail allows, joints between fire-resisting walls and floors and service gaps in risers. A single leaking joint is often how a building in Garlinge Green first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

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

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Work for main contractors and building owners

For main contractors, we work as the sealant subcontractor. Programme, specification and site rules come first, with CSCS-carded applicators on site.

When you manage a building on behalf of an owner, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.

How the quote is worked out

Before we quote, we look at:

  • Site requirements such as inductions and permits
  • How accessible the joints are
  • The total length or number of joints
  • Which sealant the job calls for

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.

Details that help us quote

We can often quote from photographs and a few details. Please tell us:

  • Approximate linear metres or a joint schedule
  • The type of building and who uses it
  • Photos of the joints, close up and from further back
  • Your programme or deadline

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

How the job changes by surface

Risers and ceiling voids

Risers and ceiling voids hold most of a building’s service penetrations. Access is often tight, so we agree it with you in advance along with any permits your site needs.

Linear joints

Joints at the top of partitions may need to move as the slab above deflects. The specified product and backing for that movement are what goes in, along the full length of the run.

Our process

Inspect, seal, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. Rural sites near Garlinge Green may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.

  1. We start with your penetration schedule, drawings or specification.
  2. We plan the sequence of floors, risers and voids with you.
  3. Each opening is checked for wall or floor type, service, gap and depth.
  4. Foam, ordinary sealant and debris come out first.
  5. Backing and fire-rated sealant are installed to the detail and tooled.
  6. We tell you about openings that need a different product.

Getting the site ready

  • Move anything stored against the joints
  • Point out any areas we must not close
  • Tell us your opening times and when work is allowed

Maintenance after handover

Problems stay small when the joints are checked regularly. In particular:

  • Report damaged or disturbed seals as soon as they’re spotted
  • Put resealing into every M&E and fit-out package
  • File the specified details where the next contractor can find them
  • Include service cupboards in routine inspections

Store the specified product details somewhere the next contractor can find them. Anyone resealing later needs to know which product and detail were used.

Make reporting new openings part of every permit to work in service areas. Small habits like this stop openings building up.

Why act early in Garlinge Green

The longer openings stay, the more there tend to be: every new cable or pipe adds another. Keeping on top of it after each round of works keeps the job small. One visit to deal with every failing joint makes more sense than several trips to a place like Garlinge Green. Photos of every joint help us quote for the whole job.

There’s no price list, since every building and every scope is different. Call for a quote.

Fire stopping in Garlinge Green: the local picture

Garlinge Green is about 52 miles from central London. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls. For England, the fire stopping of penetrations is dealt with in Approved Document B. From 2 September 2029, BS 476 references are being taken out of Approved Document B, leaving BS EN 13501-2 classification as the route, subject to the Government’s transitional arrangements. What we install is set by the specification, and it goes in to the tested detail.

For a hospital such as Kent and Canterbury Hospital, 3.5 miles to the north-east of Garlinge Green, penetration sealing is normally phased ward by ward, with infection-control rules agreed first. Offices at parks like Stour Valley Business Park, 2 miles north of Garlinge Green, are re-cabled with each new tenant, and compartment walls need sealing afterwards to the tested detail. Campus buildings at universities such as University of the Creative Arts, 3.9 miles north-east of Garlinge Green, see constant changes to data and services, and fire-rated sealant goes in around new penetrations where it is specified.

Garlinge Green is about 4 miles south-west of Canterbury, in Kent. We cover commercial sites throughout Garlinge Green. Our Kent coverage takes in 931 places, from busy centres to rural villages. London is covered too, around 52 miles from Garlinge Green.

Business premises anywhere in CT4 are within our area. We also cover Petham (1 mile south-east), Shalmsford Street (1 mile north), Mystole (1 mile north-west), Chartham (2 miles north) and Anvil Green (2 miles south) for service penetrations. Bigger towns within reach include Ashford (9 miles south-west), Canterbury (4 miles north-east), Dover (13 miles south-east), Sittingbourne (15 miles north-west), Folkestone (12 miles south-east) and Whitstable (8 miles north).

Garlinge Green: questions and answers

Is Garlinge Green too far out for you?

Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.

What does the BS 476 change mean for fire-rated sealant in Garlinge Green?

Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.

Are you CHAS accredited and on Constructionline?

Yes. We are CHAS accredited and a Constructionline member, which helps with supplier vetting.

How do I request a quote?

There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photographs and a postcode.

How long will the new sealant last?

Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

Are you insured?

Yes. Mastic Doctor is fully insured, public liability included.

Is any job too small?

Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.
