Fire stopping for commercial buildings in Walton on the Hill

Facilities managers in Walton on the Hill 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’re dealing with snag lists that include open service penetrations and openings left by services added after handover, we can help, on joints between fire-resisting walls and floors, pipe penetrations and linear gaps at wall heads alike. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Walton on the Hill is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Smaller places such as Walton on the Hill still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.

We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant.

From enquiry to sign-off

We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. Smaller jobs around Walton on the Hill can be grouped with others nearby. You’ll have a fixed quote before work starts.

  1. First we confirm the product and tested details named in the specification.
  2. We sort the openings by the detail each one needs.
  3. Old or wrong materials are cut out.
  4. Where the detail needs backing, it goes in at the stated depth.
  5. Fire-rated or intumescent sealant goes in around the services and is tooled off.
  6. Completed areas are checked with you, with the records agreed when we quoted.

Preparing the site

Advice

FAQs: Walton on the Hill

Does your area include sites such as Chesterfield Business Park, near Walton on the Hill?

Yes. Estates, retail parks and business parks around Walton on the Hill, Chesterfield Business Park among them, are all within reach. To start, just speak to us on 01277 525 020 or email us with the unit, the joints involved and your access times.

Can work in a care setting near Walton on the Hill go ahead while residents are there?

Yes, with the manager deciding the order and timing of rooms. We follow the home’s own procedures throughout.

Which sealant will you use?

A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.

Can you work to our specification?

Yes. We follow the specification, along with the manufacturer’s installation guidance.

What will the job cost?

We don’t publish prices, as every site differs. Send photos or drawings and we will price it at a fixed figure.

Do you hold third-party fire-stopping installer certification?

No, and we’d rather be clear about that. Third-party schemes aren’t a legal requirement, but many clients and main contractors ask for them, so check your contract first. Where it isn’t required, we install the specified sealant to the maker’s details.

Can you send site paperwork?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.

Honest limits

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

  • Issuing fire ratings or certificates for seals
  • Large openings beyond what any sealant detail covers
  • Reviewing a building’s overall fire safety

If in doubt, call the office on 01277 525 020 or email the details over and we’ll say what we think before you book.

What we seal

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

Looking after the joints

After handover, a little attention goes a long way:

  • Check risers and ceiling voids after each round of works
  • File the specified details where the next contractor can find them
  • Don’t let anyone top up a fire seal with the wrong product
  • Put resealing into every M&E and fit-out package

Add risers, plant rooms and ceiling voids to routine fire-stopping checks. Watch for cracked sealant, new services with no seal and openings that have grown.

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.

Fire stopping in Walton on the Hill: the local picture

Walton on the Hill is about 16 miles from central London. Office refits around the commuter belt bring new cabling through fire-resisting walls. There are two care or nursing homes within about 2 miles of Walton on the Hill. Care settings depend on compartmentation, so service penetrations made during maintenance or refurbishment need sealing with the specified product. Where that’s fire-rated sealant, we install it to the manufacturer’s tested detail.

For a building at a site such as Chesterfield Business Park (2.6 miles south of Walton on the Hill), a check of penetration seals after each fit-out is good practice. For a school such as Walton-on-the-Hill Primary School, penetration sealing fits best at the end of the summer works. Campus buildings at universities such as University for the Creative Arts - Epsom, 3.5 miles north of Walton on the Hill, see constant changes to data and services, and fire-rated sealant goes in around new penetrations where it is specified.

How the job changes by surface

Plastic pipes

Plastic pipes soften and collapse in a fire. Small sizes are sometimes covered by an intumescent sealant detail. We check the pipe material and diameter against the detail before we start.

Risers and ceiling voids

Service risers and the voids above ceilings are where openings collect. Access to these areas is planned with you in advance along with any permits your site needs.

Quoting for work in Walton on the Hill

What shapes the price:

  • Specialist products, such as fire-rated or hygienic sealants
  • How much existing material needs removing
  • Access and working height
  • Joint width, depth and condition

We don’t publish prices, since every building and every scope is different. Call for a quote and we will price your job on its own details.

Sending details for a quote

Good information means a firmer quote. When you get in touch, include:

  • Access details, including height
  • The type of building and who uses it
  • Specification clauses that apply
  • Rough lengths or quantities, or drawings if you have them

Every quote starts with the facts: the joints involved, quantities, access and the product called for. Share whatever details you have and we’ll fill any gaps with a visit.

Should maintenance staff do it?

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
