About our fire stopping in Cross-at-Hand

It helps to set out our role at the start. The designer, fire engineer or building control decides which fire stopping is required; sign-off sits with them too. We fit the specified fire-rated sealant following that specification and the maker’s installation guidance. If you are dealing with fire sealant pulled out of the opening and seals disturbed by maintenance and left open, we can help. Whoever orders the work in Cross-at-Hand, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.

Barn and farm-building conversions near places like Cross-at-Hand 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.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

From enquiry to sign-off

Inspect, seal, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. For a building around Cross-at-Hand, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.

  1. First we go through the drawings, schedule or specification for the seals.
  2. Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
  3. Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
  4. Mineral wool or other backing goes in wherever the detail asks.
  5. We apply the specified sealant to the depth and around the services as the detail shows.
  6. If an opening needs something other than sealant, we tell you instead of improvising.

What we need from you

  • Have the specification and drawings to hand
  • Point out parking and an unloading spot
  • Point out any areas we must not close

Site staff or a sealant specialist?

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Honest limits

Not every problem is a sealant problem, and we are upfront when that’s the case. These need a different solution:

  • Fire doors, dampers or other fire safety equipment
  • Walls or floors that aren’t fire-resisting to begin with
  • Deciding what a wall or floor needs, which belongs to the designer

Not sure which it is? You can give us a call on 01277 525 020 or email drawings and photos and we’ll tell you honestly.

Surfaces we seal

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

What affects the price in Cross-at-Hand

The price varies from site to site. Expect it to depend on:

  • The site’s rules and procedures
  • Working within restricted access windows
  • The total length or number of joints
  • How much existing material needs removing

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.

What to include in your enquiry

However big the job, these details speed things up:

  • Your programme or deadline
  • Whether an asbestos survey exists
  • How the joints are reached, and at what height
  • Clear photos of the problem areas

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, call 01277 525 020 or use the quote form.

Why act early in Cross-at-Hand

Open penetrations multiply: each new service adds to the list. Keeping on top of it after each round of works keeps the job small. Halls, stores and units around places like Cross-at-Hand may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.

FAQs: Cross-at-Hand

Is a smaller place like Cross-at-Hand outside your area?

Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.

Is Barradale Farm Industrial Estate, near Cross-at-Hand, within your area?

Yes, sites like Barradale Farm Industrial Estate are within our area, along with the rest of Cross-at-Hand. Photos and a short description are enough for a first look.

Do you work to architects’ specifications?

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

When can the area be used after sealing?

We will confirm how long the chosen product needs to cure.

How do you deal with asbestos in old sealant?

Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.

Do you design or specify fire stopping?

No, that isn’t our role. With the designer’s details in hand, we can price the sealant elements.

When is resealing likely to be due?

Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
