Fire stopping in Loxhill

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

How we handle fire stopping in Loxhill

We are commercial sealant applicators, CHAS accredited and a Constructionline member, with CSCS-carded applicators on site. We hold no third-party fire-stopping installer certificate and we’d rather say that up front. We install the specified fire-rated sealant to its tested detail, and our workmanship carries a 12-month guarantee. If you have fire stopping installed outside its tested range and head-of-wall gaps with no fire seal, we can put it right. Whether you call it commercial sealant work, mastic application or joint sealing, in Loxhill it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

For a smaller site near Loxhill, we plan to do all the penetrations in one go, so send the specification and photographs first. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

What we are called out for in Loxhill

Most open service penetrations are left by later work. New cabling, rerouted pipework or a data route drilled through a riser can leave the hole behind. Across several fit-outs, the openings add up.

It’s worth sending us details if you spot any of the following:

  • Builders’ foam or ordinary silicone in compartment walls
  • Damaged fire seals in risers and voids
  • Fire sealant pulled out of the opening
  • Snag lists that include open service penetrations

On estates like Littlemead Industrial Estate, 2.7 miles to the east of Loxhill, the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal.

Questions to ask before you book

  • How the joint faces will be prepared and primed
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Which product they’ll use, and why it suits the joint
  • How long is the guarantee, and what does it include?

Choosing a commercial sealant contractor

Doing it in-house

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Redoing a failed joint normally costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

How the quote is worked out

Your fixed quote is built from the real scope. It takes account of:

  • How accessible the joints are
  • Phasing around occupants
  • Removal of failed or old sealant
  • Specialist products, such as fire-rated or hygienic sealants

What a job costs comes down to how many linear metres there are, what has to come out first and the access. Call for a fixed quote once you have the details.

Details that help us quote

Whether it’s one area or a whole building, the same details help:

  • Rough lengths or quantities, or drawings if you have them
  • Any specification or named product
  • The type of building and who uses it
  • When you need the work done

Photos, drawings or a schedule of the joints and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.

FAQs: Loxhill

Is Littlemead Industrial Estate, near Loxhill, within your area?

Yes, sites like Littlemead Industrial Estate are within our area, along with the rest of Loxhill. Photos and a short description are enough for a first look.

What does the BS 476 change mean for fire-rated sealant in Loxhill?

References to BS 476 classes are being removed from Approved Document B from 2 September 2029, after which BS EN 13501-2 classification is the route, subject to transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.

Are you CHAS accredited and on Constructionline?

Yes. We’re CHAS accredited and a Constructionline member, which helps with supplier vetting.

Are you fully insured?

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

Do you take on multi-site work?

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

When can you be on site?

Give us your site hours and any access windows in your enquiry, and we will schedule the work to suit. You can reach the office between 8am and 5pm, Monday to Friday.

How soon can the area be used again?

That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.

Different surfaces, different methods

Metal pipes

Heat travels along metal pipework, and the tested detail may ask for insulation beyond the wall. We follow whatever the detail requires and flag anything we can’t match.

Risers and ceiling voids

Risers and ceiling voids hold most of a building’s service penetrations. Access is often tight, so we agree it with you in advance.

Commercial clients in Loxhill

Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, with each stage agreed with your site contact.

Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

How a job runs

In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before we move to the next. Smaller jobs around Loxhill can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.

  1. First we go through the drawings, schedule or specification for the seals.
  2. Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
  3. Unsuitable fillers and loose debris are taken out of each opening.
  4. We fit the backing the detail asks for, to the stated depth.
  5. We apply the specified sealant to the depth and around the services as the detail shows.
  6. If an opening needs something other than sealant, we tell you instead of improvising.

Getting the site ready

  • Let building users know which areas are affected
  • Clear stock, furniture or equipment away from the joints
  • Send your site hours and access windows

Advice

Service penetrations in Loxhill buildings

Loxhill lies roughly 32 miles out from central London. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls. Fire stopping of openings and penetrations in England falls under Approved Document B.

Older community buildings such as Church of St Peter that have been rewired or given new heating can have service gaps through walls worth checking against the specification. Hospital estates such as Milford Hospital (3.4 miles north-west of Loxhill) are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail.
