What we can’t put right

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • Designing or specifying fire stopping, which sits with the designer or fire engineer
  • Openings that need collars, wraps, batts or boards rather than sealant
  • Issuing fire ratings or certificates for seals

If in doubt, give us a call on 01277 525 020 or use the quote form and we will say what we think.

What we seal

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

Fire stopping in Farnham Royal, done properly

For main contractors, our fire stopping package slots in after the M&E trades have finished in an area. To price a package, call the office on 01277 525 020 or send photos by email with the schedule or marked-up drawings alongside the manufacturer’s details. Tell us what records you need and we will confirm with the quote. We work on small duct penetrations where the tested detail allows, cable penetrations and joints between fire-resisting walls and floors, and what we’re called in for most is non-fire-rated filler around services and fire seals cut back for extra cables and never reinstated. Whether you call it commercial sealant work, mastic application or joint sealing, in Farnham Royal it comes down to the same thing: the right product in a properly prepared joint.

Barn and farm-building conversions near places like Farnham Royal 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. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Doing it in-house

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.

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

On site: what to expect

We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. Jobs in and around smaller places like Farnham Royal are usually planned as a single visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

  1. We ask for the product and detail your designer has specified.
  2. We sort the openings by the detail each one needs.
  3. Old or wrong materials are cut out.
  4. Mineral wool or other backing is fitted where required.
  5. Fire-rated or intumescent sealant goes in around the services and is tooled off.
  6. We walk the completed areas with you and confirm the records agreed at quote stage.

Before we start on site

  • Make sure the joints can be reached
  • Let building users know which areas are affected
  • Agree which areas must stay open

Aftercare for building managers

Problems stay small when the joints are checked regularly. Specifically:

  • Check risers and ceiling voids after each round of works
  • Make fire stopping part of every scope that crosses a fire-resisting wall
  • Get seals inspected before ceilings and boxing close
  • Treat an open penetration as a priority repair

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.

Write fire stopping into the scope of any work crossing a compartment wall or floor. Then the seal goes in while the area is open.

Compartments and services around Farnham Royal

There are three care or nursing homes within about 2 miles of Farnham Royal. 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. A 2-mile radius around Farnham Royal takes in several hotels. Bedroom-to-corridor walls in hotels are normally fire-resisting, so new cabling or pipework through them has to be sealed to the tested detail.

In a building such as Church of St Mary, any service penetration through a fire-resisting wall should be sealed to the specified detail. At a healthcare site like Spire Thames Valley Hospital, which lies east of Farnham Royal, new services through compartment walls are a constant, and each needs the specified seal. For a unit at a site such as Slough Trading Estate, which lies south of Farnham Royal, new power or data runs between office and warehouse can breach a compartment wall.

Farnham Royal is about 2 miles north of Slough, in Buckinghamshire. Across the SL2 postcode area, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed.

Questions we’re asked in Farnham Royal

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

From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.

Is a hospital such as Spire Thames Valley Hospital somewhere you can work?

Yes, provided the work is planned with the site’s estates team. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Are you CHAS accredited and on Constructionline?

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

What do you charge?

We don’t publish prices, because every site is different. Send photographs or drawings and we will price it at a fixed figure.

Are you insured?

Yes. We are fully insured, including public liability cover.

Will your applicators have CSCS cards?

Yes. Our applicators hold CSCS cards.

Can one quote cover more than one building?

Yes. Several buildings can share a single quote, with one point of contact across South East England, Greater London and Scotland.

Surface by surface

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.

Risers and ceiling voids

Voids hide a lot of unsealed openings. We work through the areas on your schedule methodically and tell you about openings outside the list.
