Common questions from Preston clients

Is Preston too far out for you?

Not at all: smaller places are covered as well as towns. Every Scottish council area is within our area. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.

Can you work on a hospital site such as Belhaven Hospital?

Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.

Do you work to architects’ specifications?

Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.

When can the area be used after sealing?

The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.

Do the same rules apply to fire stopping in Scotland?

Our work covers Greater London, the South East and every Scottish council area. Scotland’s non-domestic Technical Handbook, clause 2.1.14, expects service penetrations to be fire stopped to at least the wall or floor’s fire resistance, using products tested for their end use.

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 if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.

Will you just go over the old sealant?

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

Fire stopping in Preston, done properly

We should be clear about what we do and don’t do. The designer, fire engineer or building control decides which fire stopping is required; sign-off sits with them too. What we bring is careful installation of the specified sealant, to the maker’s guidance on sites in Preston. Site teams most often ask us about fire seals cut back for extra cables and never reinstated and penetration schedules that need working through, across cable penetrations, pipe penetrations and joints between fire-resisting walls and floors. One point of contact handles commercial sealant work in Preston from the first photographs to the final walk-round, for single jobs and planned programmes alike.

Hotels and care homes around smaller places like Preston often have services added during refurbishment. A round of checks after M&E work is good practice, and any gaps found are sealed where fire-rated sealant is specified.

Building owners and contractors get the same cover: 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.

For managing agents and facilities managers

FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.

As a CHAS accredited contractor and Constructionline member, we’re straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.

How the quote is worked out

Quotes vary with the job. It mainly depends on:

  • Backing rod, priming and other preparation
  • Phasing around occupants
  • Any access equipment needed
  • The total length or number of joints

The specified product makes a difference, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site rules also count.

Before you send an enquiry

There’s no need for a formal survey. A few details are enough to get going:

  • Access details, including height
  • The site address and postcode
  • Whether an asbestos survey exists
  • Drawings or a marked-up plan, if available

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

Honest limits

Part of a good diagnosis is knowing where sealant stops. You’ll hear from us if the cause turns out to be any of the following:

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

If you’re not sure, just speak to us on 01277 525 020 or use the quote form and we’ll give you a straight answer before you book.

Surfaces we seal

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

After the work

For the best life from the joints:

  • Don’t let anyone top up a fire seal with the wrong product
  • Settle who seals which penetrations at the start of a project
  • Include service cupboards in routine inspections
  • Put resealing into every M&E and fit-out package

After the work, brief anyone else working in the area that the openings are now sealed. Any seal cut back for a new service needs reinstating to its tested detail using the same product.

On fit-outs, get the fire-stopping specification agreed before the services go in. The designer can then choose details that suit the services planned, and installation follows the programme.

Why act early in Preston

Leave a penetration open and smoke and fire can cross into the next compartment far earlier than intended. While the openings can be reached, sealing them is normally straightforward. Left until ceilings are closed or a tenant moves in, the same work costs more access and more disruption. Exposed buildings in Scotland take a lot of weather, so it’s worth renewing joints around Preston before they leak.

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

How a job runs

At the end of each section, we remove the tape, clean down and inspect every joint, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. For work around Preston, we aim for one trip, which is why we ask for photographs and a full list first. Outside work also needs a suitable weather window.

  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. We tell you about openings that need a different product.

Getting the site ready

  • Let us know about inductions and permits
  • Tell staff and tenants when we will be in
  • Tell us your opening times and when work is allowed

Service penetrations in Preston buildings

In Scotland, clause 2.1.14 of the non-domestic Technical Handbook expects service penetrations to keep at least the fire resistance duration of the wall or floor, with proprietary products, intumescent ones included, tested for their end use. We install what’s specified, to the product’s tested detail. The area within 2 miles of Preston holds several hotels. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal.

For a building such as Prestonkirk Parish Church, new heating or data runs are the usual reason penetrations need sealing. Large healthcare estates like Belhaven Hospital (4.3 miles east of Preston) change their services often, so penetration seals are worth checking after M&E work. Hotels such as Harvesters Hotel, 0.6 miles south-west of Preston, rely on fire-resisting walls between bedrooms and corridors, and refits that add services leave penetrations to seal where fire-rated sealant is specified.

Preston is about 5 miles west of Dunbar, in East Lothian. Businesses, contractors and managing agents in Preston use us for work on service penetrations, as part of our coverage of East Lothian. Preston is one of 48 places we cover in East Lothian. For work in that direction, see our Edinburgh page, about 22 miles away.
