Commercial clients in Seawick

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 Seawick can sit alongside others in a wider programme.

We work for building owners and managing agents on everything from one building to a spread of sites around Seawick. One quote can cover more than one site, which keeps the paperwork simple.

Fire stopping for commercial buildings in Seawick

Fire-rated sealant suits many small service penetrations: copper and steel pipes, cables and some small ducts where the tested detail allows. 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. The enquiries we see most involve expanding foam used as fire stopping and penetration schedules that need working through, across service gaps in risers, joints between fire-resisting walls and floors and small duct penetrations where the tested detail allows. A single leaking joint is often how a building in Seawick 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.

Rural conversions around Seawick can put new fire-resisting partitions inside older structures. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.

Whoever the client is, the cover is the same: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

When to bring in a 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. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

Your questions answered

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

Yes, healthcare and care buildings are part of our work. We follow the site’s permits, sign-in and infection-control procedures in every area.

Can you work at a site such as Newman Industrial Estate, by Seawick?

Yes. We cover Seawick and the area around it, including industrial estates, business parks and retail parks such as Newman Industrial Estate. Photos and a short description are enough for a first look.

What do BS EN 1366-3 and BS EN 13501-2 mean?

In short, BS EN 1366-3 and 1366-4 are the fire tests and BS EN 13501-2 is how results are classified. An EI 60 seal kept its integrity and insulation for 60 minutes as tested; installing to the detail is what carries that across to site.

Can you fire stop behind the services contractors?

Yes, where there is a specification for those walls and floors. Openings left by new services are among the most common jobs we see and we close them with the specified product.

Can one quote cover more than one building?

Yes. A group of buildings can go on one quote, with one point of contact.

Do you seal on top of existing sealant?

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

How do I request a quote?

There are four steps: send details, get a quote, we seal, guaranteed. The first step only needs photos and a postcode.

How the job changes by surface

Metal pipes

Copper and steel pipes are a common service penetration for fire-rated sealant. Pipe diameter, annular gap, sealant depth and any pipe insulation all have to match the detail and we confirm each before sealing.

Cables and cable bundles

Data cabling added after handover is a regular cause of open service penetrations. Openings around new cables are resealed to the detail, and we tell you if the bundle exceeds what sealant covers.

Diagnose, treat, sign off

When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before any cutting starts, and the work typically takes a single visit for a short list of penetrations, or a phased programme for a whole building. If others near Seawick need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

  1. First we confirm the product and tested details named in the specification.
  2. We sort the openings by the detail each one needs.
  3. Old or wrong materials are cut out.
  4. Mineral wool or other backing is fitted where required.
  5. We gun the sealant in to the specified depth around each service and tool it.
  6. We walk the completed areas with you and confirm the records agreed at quote stage.

Before we start on site

  • Send asbestos survey details if the building is pre-2000
  • Flag any permit to work we will need
  • Tell staff and tenants when we’ll be in

Quoting for work in Seawick

The price varies from site to site. It mainly depends on:

  • Site requirements such as inductions and permits
  • Quantities, in metres or numbers
  • Specialist products, such as fire-rated or hygienic sealants
  • Travel to remote or island sites

The product called for affects the cost, as does the preparation each joint needs. Access, phasing and site requirements come into it too.

Sending details for a quote

We can often quote from photographs and a few details. It helps to include:

  • Clear photos of the problem areas
  • Approximate linear metres or a joint schedule
  • Where the site is, with the postcode
  • What the building is and how it’s used

For a fixed quote, ring 01277 525 020 or email us. You can also send details through our quote form.

Compartment walls and floors in Seawick

For England, the fire stopping of penetrations is dealt with in Approved Document B. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail. Central London is about 54 miles from Seawick. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls.

Wherever services are added at a hospital such as Clacton Hospital, 2.9 miles east of Seawick, the compartment line has to be made good with the specified product. Colleges such as Adult Community College Clacton (to the north-east of Seawick) add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product. For a unit at a site such as Newman Industrial Estate (2.7 miles north-east of Seawick), new power or data runs between office and warehouse can breach a compartment wall.

Seawick is about 3 miles south-west of Clacton-on-Sea, in Essex. Any commercial site in Seawick is covered. We work across 644 places in Essex. Sites around London have their own page, about 54 miles away.

Postcode districts covered here: CO16. Among the streets we cover are Seawick Road, Willow Avenue and Links Road, and sites on any of them can send details for a fixed quote. Close to Seawick, our area also takes in Jaywick (1 mile east), Lee-over-Sands (1 mile west), St Osyth (2 miles north), Rush Green (2 miles north-east) and Point Clear (3 miles north-west). A short drive away, we cover Colchester (11 miles north-west), Clacton-on-Sea (3 miles north-east), Harwich (13 miles north-east), Camulodunum (12 miles north-west), Greenstead (10 miles north-west) and Burnham-on-Crouch (15 miles south-west).

When it isn’t the sealant

Before quoting, we check that sealant is the right answer. It isn’t the answer for:

  • Large openings beyond what any sealant detail covers
  • Writing the fire-stopping specification
  • Approving the work on behalf of building control

If in doubt, give us a call on 01277 525 020 or email us and we’ll say what we think.

Joints and surfaces we work on

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