How we handle fire stopping in Potters Corner

Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. We hold no third-party fire-stopping installer certificate. What we offer is careful installation of the specified sealant to its tested detail, with a 12-month guarantee on our workmanship. We work on pipe penetrations, service gaps in risers and linear gaps at wall heads, and the usual reasons a site gets in touch are improvised or mixed-product fire seals and head-of-wall gaps with no fire seal. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Potters Corner, preparation and product choice get the time they need.

Barn and farm-building conversions near places like Potters Corner often combine new partitions with old walls. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.

Our workmanship is guaranteed for 12 months, wherever the site is. If our installation lets you down in that time, we return and fix it.

FAQs: Potters Corner

Can work at a site such as Ashford College fit around teaching?

Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

How does the removal of BS 476 from Approved Document B affect fire-rated sealing in Potters Corner?

Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.

Do you take on multi-site work?

Yes. A group of buildings can go on one quote, with one point of contact across South East England, Greater London and Scotland.

Can you work to our specification?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.

Do you work in Potters Corner?

Yes. We cover Potters Corner, and the simplest way to start is to call the office on 01277 525 020 or email a schedule or drawings.

Can you fit around our working hours?

We are in the office from 8am until 5pm, Monday to Friday. Let us know your site hours and access windows, and the work will be planned around them.

How soon can the area be used again?

We’ll confirm how long the chosen product needs to cure, and sign any area that should be left alone.

When to call us in Potters Corner

Openings in fire-resisting walls usually appear when services are added or changed. A new cable pulled by an electrician, a pipe rerouted by a plumber or a data run drilled through a riser can leave the hole behind. Over a few years of fit-outs, a wall can collect a lot of these.

Things that typically lead to an enquiry:

  • Fire-rated sealant that has cracked or shrunk back
  • Fire seals cut back for extra cables and never reinstated
  • Snag lists that include open service penetrations
  • Non-fire-rated filler around services

In a school such as Goat Lees Primary School, fire-rated sealant goes in around service penetrations where it is specified.

Before you book anyone

  • How long is the guarantee, and what does it include?
  • Proof of insurance
  • How joint depth will be controlled
  • Whether their applicators hold CSCS cards

Choosing a commercial sealant contractor

Should maintenance staff do it?

Putting right a botched joint often costs more than sealing it well at the start, 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.

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Our process

Occupied buildings need a little choreography. We sign and contain the area we are in, keep walkways clear and move on in phases so staff and visitors can carry on around us. For a building around Potters Corner, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.

  1. We read the specification, drawings or penetration schedule you send.
  2. On site, each opening is checked against the tested detail it is meant to follow.
  3. Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
  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. Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.

Before we start on site

  • Have the specification and drawings to hand
  • Tell us your opening times and when work is allowed
  • Tell us what induction or permit system the site runs

Fire stopping around Potters Corner: how the place shapes the job

Potters Corner is about 47 miles from central London. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls. There are plenty of hotels within about 2 miles of Potters Corner. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal.

Tenant changes at parks like Eurogate Business Park (0.9 miles south-east of Potters Corner) bring new data and services, and openings through fire-resisting walls need the specified seal. At a college such as Ashford College, 2 miles south-east of Potters Corner, checking penetration seals after summer M&E works is good practice.

What sets the cost

These are the things that shape the price:

  • Phasing around occupants
  • The site’s rules and procedures
  • Quantities, in metres or numbers
  • Any access equipment needed

The specified product makes a difference, as does the preparation each joint needs. Access, phasing and site requirements come into it too.

Before you send an enquiry

A few photos plus some basic facts will normally do. Please tell us:

  • When you need the work done
  • Access details, including height
  • The site address and postcode
  • Drawings or a marked-up plan, if available

Send us photos, drawings or a joint schedule and a fixed quote comes back to you. Where a site visit makes more sense, we will arrange one.

Keeping the joints sound

After handover, these steps help:

  • Check with the data sheet before painting over fire sealant
  • Record which product was used where
  • Look above ceilings when tiles are lifted for other jobs
  • Settle who seals which penetrations at the start of a project

After every round of M&E works, check that the openings created have been sealed. Building it into each contractor’s sign-off keeps the walls intact.

Keep a register of where seals are and what they are made of. When a new service goes through, everyone knows which product and detail to match, which saves guesswork.

Why it’s worth doing now in Potters Corner

Open service penetrations matter on ordinary days, not just in a fire: smoke, noise and draughts pass through them every day. Sealing them to the specified detail deals with the fire risk first and the building feels the difference. For buildings around smaller places like Potters Corner, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.
