Fire stopping in Pitchcott, done properly

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. We work on pipe penetrations, linear gaps at wall heads and service gaps in risers, and what we’re called in for most is fire-stopping items raised at inspection or handover and unsealed joints where partitions meet the slab. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Pitchcott is the same: the right product in a properly prepared joint.

For a smaller site near Pitchcott, we plan to do all the penetrations in one go, with the specification and photos sent in advance. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.

We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Different surfaces, different methods

Masonry and concrete

Many seals are made in blockwork, brickwork or concrete slabs. Dust and loose debris are cleared out of the opening, so the sealant and any backing sit properly.

Risers and ceiling voids

Voids hide a lot of unsealed openings. We follow your schedule area by area and tell you about openings outside the list.

Fire-rated sealing for Pitchcott buildings

Fire stopping of openings and penetrations in England falls under Approved Document B. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail. Pitchcott lies roughly 42 miles out from central London. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls.

On a hospital site such as Royal Buckinghamshire Hospital, which lies south-east of Pitchcott, fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits. Older community buildings such as Church of St. Giles that have been rewired or given new heating can have service gaps through walls worth checking against the specification.

Pitchcott is about 4 miles north of Haydon Hill, in Buckinghamshire. Across the HP22 postcode area, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Pitchcott is one of 308 places we cover in Buckinghamshire. We also cover Oxford, around 18 miles from Pitchcott.

Your questions answered

How does the move away from BS 476 affect penetration seals in Pitchcott?

From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.

Can you work on a hospital site such as Royal Buckinghamshire Hospital?

Yes. We work in healthcare settings as well as offices and schools. We follow the site’s permits, sign-in and infection-control procedures in every area.

Are you CHAS accredited and on Constructionline?

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

Can you fit around our working hours?

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

Is it fine to apply new sealant on top of old?

No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.

What will the job cost?

Each job is quoted on its own details. For yours, call 01277 525 020 or use the quote form.

Do you cover Pitchcott?

Yes. We cover Pitchcott, and the simplest way to start is to call the office on 01277 525 020 or use the quote form.

Our process

Before we leave any area, we remove the tape, clean down and inspect every joint with your site contact. Where the sealant needs time to cure before use, we tell you and sign the area. For work around Pitchcott, we aim to finish in one visit, so photographs and measurements up front really help. That way the right products come on the day.

  1. We ask for the product and detail your designer has specified.
  2. We sort the openings by the detail each one needs.
  3. Improvised fillers and failed sealant are removed.
  4. Where the detail needs backing, it goes in at the stated depth.
  5. We gun the sealant in to the specified depth around each service and tool it.
  6. We walk the completed areas with you and confirm the records agreed at quote stage.

Preparing the site

  • Tell us which areas need to stay in use
  • Tell staff and tenants when we will be in
  • Send your site hours and access windows

Getting a fixed quote

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, phone 01277 525 020 or send photos by email.

Do you need fire stopping in Pitchcott?

Some seals fail because the wrong product went in: builders’ foam or ordinary silicone used to fill a hole. It may look closed, but it has no tested fire performance in that position, so it has to come out.

Common reasons buildings call us in:

  • Expanding foam used as fire stopping
  • Open linear gaps along the top of fire-resisting walls
  • Unsealed openings around new pipes and cables
  • Openings found when ceilings come down for a refit

Holiday works at schools like Whitchurch Combined School often leave service openings to seal before pupils return.

Questions to ask before you book

  • Will CSCS-carded applicators be on site?
  • Do they follow the manufacturer’s priming guidance?
  • Are they CHAS accredited or on Constructionline?
  • Proof of insurance

How to choose a sealant contractor

What sets the cost

Quotes vary with the job. It mainly depends on:

  • Site requirements such as inductions and permits
  • How accessible the joints are
  • The product specified
  • The total length or number of joints

We don’t publish prices, since every building and every scope is different. For a fixed figure, call for a quote and we’ll price your job on its own details.

Sending details for a quote

To price the job accurately, we need to understand the site. Send us:

  • Approximate linear metres or a joint schedule
  • Where the site is, with the postcode
  • Any dates the work must fit around
  • The asbestos register, for older buildings

For a fixed quote, phone 01277 525 020 or send details through our quote form. You can also send details through our quote form.

General trades versus a specialist

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

Maintenance after handover

A few simple habits keep the new joints working:

  • Settle who seals which penetrations at the start of a project
  • Brief every trade that openings they make must be sealed
  • Report damaged or disturbed seals as soon as they’re spotted
  • Keep product data and details in the fire safety file

New services after handover are a common way fire stopping gets breached. Building it into each contractor’s sign-off keeps the walls intact.

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.
