Fire stopping in Upton Grey

We should be clear about what we do and don’t do. Deciding the specification sits with the designer, the fire engineer and building control; sign-off sits with them too. What we bring is careful installation of the specified sealant, to the maker’s guidance in Upton Grey and nearby. If you’re dealing with seals disturbed by maintenance and left open and improvised or mixed-product fire seals, we can put it right, whatever the surface. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Upton Grey is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Rural conversions around Upton Grey 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.

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Should maintenance staff do it?

Site maintenance staff can often handle a short internal joint. 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. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

How the quote is worked out

We price every job individually. The main factors are:

  • Travel to remote or island sites
  • Specialist products, such as fire-rated or hygienic sealants
  • How much existing material needs removing
  • Joint width, depth and condition

We don’t publish prices, since every building and every scope is different. For a fixed figure, call for a quote.

Before you send an enquiry

A good diagnosis starts with the right details. Tell us:

  • The asbestos register, for older buildings
  • Where the site is, with the postcode
  • A wide shot and a close-up of the area
  • The type of building and who uses it

Send us photographs, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.

FAQs: Upton Grey

Is Hatch Industrial Park, near Upton Grey, within your area?

Yes. Estates, retail parks and business parks around Upton Grey, Hatch Industrial Park among them, are all within reach. Photos and a short description are enough for a first look.

Can you work on a hospital site such as Basingstoke and North Hampshire Hospital?

Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

How long does a job like this take?

We plan the time on site around your programme and access. We’ll give you an estimate of time on site when we quote.

What do you charge?

That depends on the job: quantities, access, the product and any phasing. Call for a fixed quote and we will price it properly.

Can you fire stop behind the services contractors?

Yes. Send the schedule or marked-up drawings and the specified product details for a fixed quote. Work can run area by area behind the M&E trades so areas aren’t left open.

What happens if old sealant might contain asbestos?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. 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?

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.

Our process

Diagnose, treat, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. Smaller jobs around Upton Grey can be grouped with others nearby. A fixed quote is given before anything starts.

  1. We read the specification, drawings or penetration schedule you send and raise any questions before we price.
  2. On site, each opening is checked against the tested detail it is meant to follow.
  3. Unsuitable fillers and loose debris are taken out of each opening.
  4. Mineral wool or other backing goes in wherever the detail asks.
  5. Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
  6. Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.

Getting the site ready

  • Let building users know which areas are affected
  • Have the specification and drawings to hand
  • Send your site hours and access windows

Quotes

Every quote starts with the facts: the joints involved, quantities, access and the product called for. Send what you have, and we’ll arrange a site visit if anything is unclear.

Service penetrations in Upton Grey buildings

For England, the fire stopping of penetrations is dealt with in Approved Document B. 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. We install whatever has been specified, to the product’s tested detail. Central London is about 44 miles from Upton Grey. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls, and the gaps need sealing with the specified product.

On estates like Hatch Industrial Park, which lies north-west of Upton Grey, the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal. Large healthcare estates like Basingstoke and North Hampshire Hospital, 5.8 miles north-west of Upton Grey, change their services often, so penetration seals are worth checking after M&E work.

Upton Grey is about 5 miles south-east of Basingstoke, in Hampshire. Upton Grey sits inside our coverage and the rest of Hampshire, with the same fixed quotes and 12-month guarantee as everywhere else.

Signs you need fire stopping in Upton Grey

Head-of-wall joints and wall-to-wall junctions are frequent weak points. Movement in the frame or slab can open the joint, and a product not tested for that movement may crack. Linear joint details set a width range and movement capability, and the seal has to sit within them.

Clients usually get in touch after noticing one or more of the following:

  • Unsealed joints where partitions meet the slab
  • Hidden openings found during inspections
  • Fire seals cut back for extra cables and never reinstated
  • Openings left by services added after handover

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

What to look for in a quote

  • Can the work be phased to keep areas open?
  • Which product they’ll use, and why it suits the joint
  • What site paperwork they can supply
  • Their approach to joint depth and backing

How to choose a sealant contractor

After the work

Your facilities or cleaning team can help the joints last. Pass these on to them:

  • Arrange inspection before areas are covered up
  • Make fire stopping part of every scope that crosses a fire-resisting wall
  • Keep product data and details in the fire safety file
  • Agree the fire-stopping specification before services go in

After the work, brief anyone else working in the area that the openings are now sealed. If a seal has to be opened for a new service, it should be reinstated to the same detail, by someone who knows the system.

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, not months later.
