Fire stopping in Hoe Gate

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

What we can’t put right

Honesty saves time and money. Fresh joints won’t solve:

  • Fire risk assessments, a job for a competent assessor
  • Issuing fire ratings or certificates for seals
  • Gaps in walls that were never built as compartment walls

If you are not sure, just ring 01277 525 020 or use the quote form and we’ll give you a straight answer.

Joints and surfaces we work on

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

Fire stopping in Hoe Gate, done properly

Facilities managers in Hoe Gate often find open service penetrations when ceilings come down for other work. Where the walls and floors already have a fire-stopping specification, we can work to it. With no specification in place, the first step sits with your designer or fire engineer, not with us. If you are dealing with openings left by services added after handover and fire stopping installed outside its tested range, we can help. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Hoe Gate, preparation and product choice get the time they need.

Barn and farm-building conversions near places like Hoe Gate often combine new partitions with old walls. A penetration seal only performs as tested if product, substrate, service, gap and depth all match the detail.

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

How the quote is worked out

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

  • The size and state of each joint
  • How much there is to seal
  • Removal of failed or old sealant
  • Phasing around occupants

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

Sending details for a quote

The more we know, the firmer the quote. When you get in touch, include:

  • The asbestos register, for older buildings
  • Specification clauses that apply
  • The postcode of the building
  • The type of building and who uses it

Need a figure for a tender or a budget? Send the scope and any drawings, and we’ll return a fixed quote that you can work with. If you have questions first, phone 01277 525 020 or send photos by email.

Leave it or put it right?

The longer openings stay, the more there tend to be: every new cable or pipe adds another. A schedule that is dealt with regularly stays manageable. Converted and older buildings near places like Hoe Gate tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.

What you get with us

  • Specification-led, product-correct work
  • One contact handling all your sites
  • Over 20 years of commercial sealing
  • Workmanship guaranteed for 12 months

Common questions from Hoe Gate clients

Is Hoe Gate too small for you to travel to?

Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Good photos up front let us bring everything on the first visit.

Can you work at a site such as Parklands Business Park, by Hoe Gate?

Yes, sites like Parklands Business Park are within our area, along with the rest of Hoe Gate. Send details of the unit and the work through our quote form for a quick quote.

Is fire stopping in Scotland covered by different guidance?

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, with proprietary products tested for the end use.

How many days will you need on site?

The duration is planned around your programme and the access we are given. You’ll have an expected duration with the quote.

Who decides which product is used?

Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Do you guarantee your work?

Yes, for 12 months. If a joint fails because of how we installed it, we come back and put it right.

Can you work to our specification?

Yes. Send it with your enquiry, and the quote will be based on it.

How the job changes by surface

Linear joints

Linear joints run along the head of a wall, at a slab edge or between two fire-resisting elements. BS EN 1366-4 testing sets the joint widths, depths, backing and movement a seal covers.

Small ducts

Small ductwork can sometimes be sealed with sealant where the tested detail includes it. Bigger ducts and fire-resisting ductwork are normally handled with other products, and we will say if that applies.

Compartment walls and floors in Hoe Gate

Fire stopping of openings and penetrations in England falls under Approved Document B. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. Either way, we install the specified product to its tested detail. Hoe Gate is about 60 miles from central London. Office refits around the commuter belt bring new cabling through fire-resisting walls; the gaps need the specified seal.

Offices at parks like Parklands Business Park (to the south-east of Hoe Gate) are re-cabled with each new tenant, and compartment walls need sealing afterwards to the tested detail. At a healthcare site like Knowle Hospital, which lies south-west of Hoe Gate, new services through compartment walls are a constant, and each needs the specified seal. Older community buildings such as Church of the Holy Trinity that have been rewired or given new heating can have service gaps through walls worth checking against the specification.

Hoe Gate is about 4 miles north-west of Waterlooville, in Hampshire. We cover Hoe Gate, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Hoe Gate is one of 723 places we cover in Hampshire. Sites around Portsmouth have their own page, roughly 7 miles from Hoe Gate.

Our process

Inspect, seal, 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 we finish with a walk round so the work can be signed off. If others near Hoe Gate need work, visits can be combined. You will have a fixed quote before work starts.

  1. First we go through the drawings, schedule or specification for the seals 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. We apply the specified sealant to the depth and around the services as the detail shows.
  6. Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.

What we need from you

  • Send any specification or drawings in advance
  • Share the asbestos register for older buildings
  • Flag any permit to work we’ll need
