Fire stopping near Ashley Heath

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Maintenance after handover

Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. We suggest:

  • Report damaged or disturbed seals as soon as they’re spotted
  • Ask which product is in place before decorating
  • Ask the designer to confirm details early on refits
  • Include service cupboards in routine inspections

Once the seals are in, tell other trades they exist and must not be disturbed. If a seal has to be opened for a new service, it should be reinstated to the same detail.

Write fire stopping into the scope of any work crossing a compartment wall or floor. That way the opening is sealed while the trade and access are still there.

How we handle fire stopping in Ashley Heath

Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. We don’t hold a third-party fire-stopping installer certificate, and we won’t pretend otherwise. What we offer is careful installation of the specified sealant to its tested detail, with a 12-month guarantee on our workmanship. If you’re dealing with old intumescent sealant that has split away and unsealed openings around new pipes and cables, we can help, on joints between fire-resisting walls and floors, service gaps in risers and linear gaps at wall heads alike. A single leaking joint is often how a building in Ashley Heath first comes to us: we look at the rest while we’re there and tell you what we find.

Around Ashley Heath, penetration and linear seals tend to be one-building jobs. Send the specification, drawings or photos of the openings and we’ll quote to suit.

A 12-month guarantee applies to all our work. If an installation problem shows up, phone 01277 525 020 or email a schedule or drawings and we will arrange a return visit.

When to call us in Ashley Heath

Mixing products or improvising a detail breaks the link with the test evidence. An oversized gap, too shallow a bead, missing backing or two makers’ products combined are what we find most often.

Any of the following is a good reason to get the joints checked over:

  • Fire stopping installed outside its tested range
  • Fire sealant pulled out of the opening
  • Builders’ foam or ordinary silicone in compartment walls
  • Unsealed openings around new pipes and cables

Older community buildings such as All Saints that have been rewired or given new heating can have service gaps through walls worth checking against the specification.

What your quote should include

  • Will CSCS-carded applicators be on site?
  • Is the sealant right for the movement and the substrate?
  • Will failed sealant be removed rather than covered?
  • What site paperwork they can supply

Choosing a commercial sealant contractor

General trades versus a specialist

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.

Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.

What we can’t put right

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

  • Writing the fire-stopping specification
  • Gaps in walls that were never built as compartment walls
  • Plastic pipes whose detail calls for a collar or wrap

If you are not sure, just phone 01277 525 020 or email us and we will give you a straight answer before you book.

Surfaces we seal

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

For managing agents and facilities managers

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.

We work for building owners and managing agents on sealant work across single buildings or whole portfolios around Ashley Heath. Several sites can go on one quote, so there’s one set of paperwork to deal with.

Diagnose, treat, sign off

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 the next one starts. For a job in Ashley Heath, the main thing is a clear picture of the work, so send photographs of each area. You will then get a fixed price for the work.

  1. We start with your penetration schedule, drawings or specification.
  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 first.
  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.

Before we start on site

  • Let us know about inductions and permits
  • Warn occupants and staff about the work
  • Tell us which areas need to stay in use

Get a fixed quote

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, give us a call on 01277 525 020 or email the details over.

Service penetrations in Ashley Heath buildings

In England, Approved Document B covers fire stopping of openings and penetrations. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. Our part stays the same: the specified product, installed to its tested detail. The area within 2 miles of Ashley Heath holds a number of hotels. Bedroom-to-corridor walls in hotels are normally fire-resisting, so new cabling or pipework through them has to be sealed to the tested detail.

Large healthcare estates like St Leonards Hospital (1.6 miles south-west of Ashley Heath) change their services often, so penetration seals are worth checking after M&E work. For a site team at a college like Sheiling College (1.1 miles east of Ashley Heath), fire-rated sealing is best scheduled after the summer works.

Ashley Heath is in Hampshire. We send applicators to Ashley Heath for service penetrations. Ashley Heath is one of 723 places in Hampshire on our list. For work in that direction, see our Southampton page (20 miles or so).

Questions we’re asked in Ashley Heath

Can you work on a hospital site such as St Leonards Hospital?

Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Can you seal penetrations in a hotel in Ashley Heath after a refit?

Yes, to the specification and the product’s tested detail. Work is done room by room so the hotel keeps trading; design and sign-off stay with the designer and building control.

What do you charge?

Each job is quoted on its own details. For yours, ring 01277 525 020 or use the quote form.

Can you quote from photos?

That depends on the size and complexity of the job. Simple work can often be priced from photographs, and bigger or more complex jobs typically get a visit.

How long does a typical visit take?

That varies with the scale of the job, though a typical visit typically takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.

Can the sealant be colour-matched?

In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We’ll confirm the colours available for the specified product.

Is it fine to apply new sealant on top of old?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
