Fire stopping for Bishop's Waltham sites

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

Aftercare for building managers

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

  • Include service cupboards in routine inspections
  • Have penetrations checked while they can still be seen
  • Put resealing into every M&E and fit-out package
  • Report damaged or disturbed seals as soon as they’re spotted

Give the sealant its full cure time before ceilings, boxing or decoration go over it. Some fire-rated sealants accept paint and some don’t, so check the product data first.

Keep a register of where seals are and what they are made of. It tells the next contractor exactly what to reinstate, and it helps at inspections.

How we handle fire stopping in Bishop's Waltham

A lot of fire-stopping work comes after M&E installation, a refit or a tenant fit-out. Each new cable, pipe or data route cut through a fire-resisting wall leaves an opening behind, often unnoticed. Those on your schedule are closed with the specified product. We work on joints between fire-resisting walls and floors, linear gaps at wall heads and pipe penetrations, and the failures we’re asked to look at most are unsealed joints where partitions meet the slab and fire seals cut back for extra cables and never reinstated. Looking for mastic applicators who cover Bishop's Waltham? We have been sealing commercial buildings since 2005.

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

Every job is signed off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

What we can’t put right

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

  • Construction that lacks the fire resistance the seal relies on
  • Deciding what a wall or floor needs, which belongs to the designer
  • Approving the work on behalf of building control

If you’re not sure, just call the office on 01277 525 020 or email us and we will give you a straight answer.

Where we work in Bishop's Waltham

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

Why act early in Bishop's Waltham

Fire stopping is a regular point raised at inspections and handover. Finding unsealed or improvised openings late can hold up a programme which is why earlier is better. Sealant hardens, cracks and loses grip with age, UV and movement. Replacing it before it fails keeps water out.

There’s no price list, because the scope varies so much from one building to the next. Call for a quote.

Bishop's Waltham: questions and answers

What does the BS 476 change mean for fire-rated sealant in Bishop's Waltham?

Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.

Do you cover business parks and estates near Bishop's Waltham, such as Swanmore Business Park?

Yes. We cover Bishop's Waltham and the area around it, including industrial estates, business parks and retail parks such as Swanmore Business Park. To start, just call 01277 525 020 or send details through our quote form with the unit, the joints involved and your access times.

When can you be on site?

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

What happens if old sealant might contain asbestos?

Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.

How long before the joints can be used?

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

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

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.

Will you quote for a small job?

Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.

Quoting for work in Bishop's Waltham

These are the things that shape the price:

  • How accessible the joints are
  • Distance, for remote addresses
  • Whether the work must be split into stages
  • Joint width, depth and condition

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote and we will explain how it’s made up.

Details that help us quote

There’s no need for a formal survey. These details are enough to start:

  • Rough lengths or quantities, or drawings if you have them
  • A wide shot and a close-up of the area
  • Any dates the work must fit around
  • The asbestos register, for older buildings

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, ring 01277 525 020 or email the details over.

On site: what to expect

Site rules come first: sign-in, induction and whatever permit system the building uses. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. What matters most for a job in Bishop's Waltham is a clear list of what needs doing, so send photographs of each area. A fixed quote follows.

  1. The specification and schedule come first, so we know which details apply.
  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. Foam, ordinary sealant and debris come out so the seal starts clean.
  5. The specified backing and sealant go in to depth and are finished neatly.
  6. Anything outside the detail is reported to you rather than sealed.

What we need from you

  • Have the specification and drawings to hand
  • Share your working hours and any access restrictions
  • Point out parking and an unloading spot

Surface by surface

Plastic pipes

Plastic waste pipes through slabs come up often. Whether sealant alone is acceptable depends entirely on the tested detail, and we’ll never swap a specified collar for sealant.

Risers and ceiling voids

Voids hide a lot of unsealed openings. We follow your schedule area by area, and note anything we find that isn’t on it.
