Fire stopping for Frindsbury sites

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

About our fire stopping in Frindsbury

Where pipes, cables and other services cross a compartment wall or floor, the opening around them has to be closed so fire and smoke can’t move between compartments. Our part is installing fire-rated and intumescent sealant at those openings and along linear gaps, where the specification calls for it. Each seal follows the manufacturer’s tested detail. If you have fire stopping installed outside its tested range and unsealed openings around new pipes and cables, we can help. Looking for mastic applicators who cover Frindsbury? We have been sealing commercial buildings since 2005.

Fire-rated sealing in a place like Frindsbury is usually a single building at a time. With the specification and photos of the gaps, we can give a fixed quote and bring the right products.

Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If our installation lets you down in that time, we return and fix it.

Questions about Frindsbury

Do you work on fire-rated sealing in hotels in Frindsbury?

Yes, where the specification calls for fire-rated sealant. Work is done room by room so the hotel keeps trading; design and sign-off stay with the designer and building control.

Can you work at a site such as Castle View Business Centre, by Frindsbury?

Yes. Our area takes in Frindsbury and its surroundings, with estates and business parks such as Castle View Business Centre included. Photos and a short description are enough for a first look.

Can staff carry on working while you are here?

Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.

How do I request a quote?

It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photographs and a postcode.

Can weather delay the job?

Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.

Are you insured?

Yes. Our insurance certificate can be sent alongside the quote.

Who decides which product is used?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Maintenance after handover

Regular inspection catches problems early. Specifically:

  • Flag new cables with no seal around them
  • Ask which product is in place before decorating
  • Have penetrations checked while they can still be seen
  • Keep general-purpose fillers away from compartment walls

Store the specified product details somewhere the next contractor can find them. It makes later repairs much easier to match.

Make reporting new openings part of every permit to work in service areas. Small habits like this stop openings building up.

Our process

Before we leave any area, the masking comes off, the area is cleaned and every joint is checked. Where the sealant needs time to cure before use, we tell you and sign the area. Several jobs near Frindsbury can be grouped on one trip. Mention the building’s opening times and we will work within them.

  1. We start with your penetration schedule, drawings or specification.
  2. We plan the sequence of floors, risers and voids with you.
  3. Each opening is checked for wall or floor type, service, gap and depth.
  4. Unsuitable material is removed and the opening cleaned first.
  5. The specified backing and sealant go in to depth and are finished neatly.
  6. We tell you about openings that need a different product.

Before we start on site

  • Agree which areas must stay open
  • Arrange parking or a loading space
  • For older buildings, check the asbestos register before work

Quotes

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To start the process, call 01277 525 020 or email us.

What sets the cost

These are the things that shape the price:

  • The size and state of each joint
  • Any access equipment needed
  • The total length or number of joints
  • The product specified

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.

Details that help us quote

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

  • Photos of the joints, close up and from further back
  • Approximate linear metres or a joint schedule
  • What the building is and how it’s used
  • Access details, including height

Pricing a project or setting a maintenance budget? Send the scope and any drawings, and we’ll return a fixed quote you can plan around. For a chat about it beforehand, call 01277 525 020 or email drawings and photos.

Owners, agents and contractors

Hospitality, education, healthcare, office and retail clients book us directly too. We plan around the way the building is used, so the building keeps working while we do.

Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, with CSCS-carded applicators on site.

Different surfaces, different methods

Cables and cable bundles

New data and power cables are the most common breach we see. We reseal around them to the specified detail.

Drylining partitions

Service holes through plasterboard are frequently oversized or ragged. If the gap exceeds the tested range, sealant alone won’t do.

Fire stopping around Frindsbury: how the place shapes the job

Plenty of hotels sit less than 2 miles from Frindsbury. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close. Approved Document B is the English guidance that covers fire stopping around openings and penetrations. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. What we install is set by the specification, and it goes in to the tested detail.

For a site team at a college like MidKent College Gillingham Campus, 1.6 miles to the east of Frindsbury, fire-rated sealing is best scheduled after the summer works. For a hotel such as RBS Hotel, under half a mile to the west of Frindsbury, penetration seals are worth checking after any refit or services upgrade. For an estates team at a campus like University of Kent - Medway Campus (1.3 miles east of Frindsbury), summer M&E works are typically followed by a round of penetration sealing.

When it isn’t the sealant

Before quoting, we check that sealant is the right answer. It won’t put right:

  • Writing the fire-stopping specification
  • Openings that need collars, wraps, batts or boards rather than sealant
  • Walls or floors that aren’t fire-resisting to begin with

If in doubt, ring 01277 525 020 or send details through our quote form and we will say what we think.

What we seal

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