Work for main contractors and building owners

As a CHAS accredited contractor and Constructionline member, we are straightforward to vet for your supplier list. We’re fully insured, and our insurance certificate can go with the quote.

How we handle fire stopping in Broad Oak

The test standards are BS EN 1366-3 for penetration seals and BS EN 1366-4 for linear joints. A rating such as EI 60 only holds when the product is installed as it was tested. Reproducing the tested arrangement on site is the part we take care of. Site teams most often ask us about snag lists that include open service penetrations and openings left by services added after handover, on service gaps in risers, joints between fire-resisting walls and floors and linear gaps at wall heads. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Broad Oak it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

For a smaller site near Broad Oak, we plan to do all the penetrations in one go, 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.

Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

Compartments and services around Broad Oak

Broad Oak lies roughly 48 miles out from central London. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls. Approved Document B is the English guidance that covers fire stopping around openings and penetrations. 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. Our part stays the same: the specified product, installed to its tested detail.

At a healthcare site like Conquest Hospital, 4.7 miles to the south of Broad Oak, new services through compartment walls are a constant, and each needs the specified seal. For a building such as The Parish Church of St George, new heating or data runs are the usual reason penetrations need sealing. For a school such as Brede Primary School, penetration sealing fits best at the end of the summer works.

Broad Oak is about 6 miles north of Hastings, in East Sussex. Commercial clients in Broad Oak use us for work on service penetrations. We work across 308 places in East Sussex, large and small. We also cover Brighton, around 33 miles from Broad Oak.

Surface by surface

Risers and ceiling voids

Openings above suspended ceilings are easy to miss. We follow your schedule area by area and tell you about openings outside the list.

Metal pipes

Metal pipes conduct heat, so their details often call for extra measures along the pipe. We follow whatever the detail requires and flag anything we can’t match.

Common questions from Broad Oak clients

What happens to BS 476 references for fire stopping in Broad Oak?

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.

Is Broad Oak too small for you to travel to?

Not at all. Broad Oak is within our area. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.

How do you deal with asbestos in old sealant?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.

How long will the new sealant last?

Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.

Do you take on small jobs?

Small jobs are welcome alongside larger packages. Send details for a fixed quote.

Are you CHAS accredited and on Constructionline?

Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.

How many days will you need on site?

The duration is planned around your programme and the access we are given. We will give you an estimate of time on site when we quote.

Why deal with it now?

It is cheaper to seal service penetrations as each services package finishes than to come back for them later. While the area is still open, every opening is easy to see and reach, and the right detail can be checked at the time. One visit to deal with every failing joint makes more sense than several trips to a place like Broad Oak, rather than one at a time. Send photos of each area and we’ll quote for the lot.

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.

Why us?

  • Health and safety: CHAS accredited
  • One phone line for London, the South East and Scotland
  • Fully insured, including public liability cover
  • Constructionline member for supplier checks

Honest limits

Sealant solves a lot, but not everything, and we are upfront when that’s the case. It won’t fix:

  • Fire doors, dampers or other fire safety equipment
  • Large openings beyond what any sealant detail covers
  • Designing or specifying fire stopping, which sits with the designer or fire engineer

Not sure which it is? You can ring 01277 525 020 or email us and we’ll tell you honestly before you book.

Surfaces we seal

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

How a job runs

Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed, then handed back before we move to the next. For a building around Broad Oak, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.

  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. 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

  • Flag any permit to work we will need
  • Have the specification and drawings to hand
  • Tell us which areas need to stay in use

What affects the price in Broad Oak

There’s no standard rate for sealant work, because every site is different. What we take into account:

  • The product specified
  • How much existing material needs removing
  • The site’s rules and procedures
  • Working within restricted access windows

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.

Details that help us quote

Good information means a firmer quote. When you get in touch, include:

  • Access details, including height
  • Rough lengths or quantities, or drawings if you have them
  • When you need the work done
  • The type of building and who uses it

A good quote starts with a clear picture: 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.
