Fire stopping for Rainham sites

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

Aftercare for building managers

Cleaning and maintenance staff play a part too. Share these points with them:

  • Check with the data sheet before painting over fire sealant
  • Report damaged or disturbed seals as soon as they’re spotted
  • Make fire stopping part of every scope that crosses a fire-resisting wall
  • Agree the fire-stopping specification before services go in

Don’t patch a fire-rated seal with anything outside its tested detail. Repairs need the same product and detail as the original, or a new specification from the designer.

A simple record of seal locations and products helps. When a new service goes through, everyone knows which product and detail to match, which saves guesswork.

Fire stopping for commercial buildings in Rainham

It helps to set out our role at the start. Deciding the specification sits with the designer, the fire engineer and building control. What we bring is careful installation of the specified sealant, to the maker’s guidance. We work on cable penetrations, service gaps in risers and small duct penetrations where the tested detail allows, and what we are called in for most is seals that don’t match their tested detail and fire sealant pulled out of the opening. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Rainham is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

In a town such as Rainham, fire-rated sealing is often needed in schools, surgeries, care homes, offices and flats above shops. Whenever new services go through those walls, the gaps need sealing with the specified product.

Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and the quote explains what it covers.

Different surfaces, different methods

Metal pipes

Metal pipes conduct heat, so their details often call for extra measures along the pipe. If the detail needs something beyond sealant, we tell you.

Risers and ceiling voids

Voids hide a lot of unsealed openings. We work through the areas on your schedule methodically, and note anything we find that isn’t on it.

What happens if it’s left?

A seal that doesn’t match its tested detail gives false comfort. Correcting it means cutting it out and starting again with the specified product, so it makes sense to get it right first time. For businesses and landlords in Rainham, a tidy, sound joint also matters for appearance. Fresh sealant makes a building look maintained.

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.

Why clients in Rainham choose us

  • Workmanship guaranteed for 12 months
  • Constructionline member for supplier checks
  • Old sealant cut out, never sealed over
  • CSCS-carded applicators

When to bring in a specialist

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

From enquiry to sign-off

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. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Most work in Rainham is one building at a time: a school, a unit, an office or a block. Your photos, drawings or a site visit come first, followed by a fixed 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. Each opening is checked for wall or floor type, service, gap and depth.
  4. Foam, ordinary sealant and debris come out.
  5. The specified backing and sealant go in to depth and are finished neatly.
  6. Anything outside the detail is reported to you rather than sealed.

Preparing the site

  • Confirm the product named in the specification
  • Let us know about inductions and permits
  • Explain the parking and delivery arrangements

Advice

Where services cross fire walls in Rainham

A 2-mile radius around Rainham takes in a number of hotels. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal. Fire stopping of openings and penetrations in England falls under 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. Either way, we install the specified product to its tested detail.

Large healthcare estates like Medway Maritime Hospital, 3.2 miles north-west of Rainham, change their services often, so penetration seals are worth checking after M&E work. Shop fits on retail sites such as Parkwood Shopping Centre (to the south-west of Rainham) can bring new services through fire-resisting walls between units, to be sealed with the specified product. For a building such as Church of St Margaret, new heating or data runs are the usual reason penetrations need sealing.

Questions we are asked in Rainham

Does your area include sites such as Parkwood Shopping Centre, near Rainham?

Yes. We cover Rainham and the area around it, including industrial estates, business parks and retail parks such as Parkwood Shopping Centre. A few photos and the unit address let us price the work.

Can work at a site such as University of Greenwich - Medway fit around teaching?

Yes, holiday working periods are the norm on campus jobs. Let us know which documents your site asks for, and we will confirm them alongside the quote.

Does the weather affect the work?

Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.

Do you work in Scotland as well as England?

Our area runs from Greater London and the South East to every part of Scotland. In Scotland, clause 2.1.14 of the non-domestic Technical Handbook says service penetrations should keep at least the fire resistance of the wall or floor, using products tested for their end use.

What about RAMS and site documents?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.

Do you have public liability insurance?

Yes. We are fully insured, including public liability cover.

When is resealing likely to be due?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
