Why it’s worth doing now in Dippenhall

Sealing behind the M&E trades area by area beats a sweep at the end. While the area is still open, every opening is easy to see and reach. Older rural buildings around Dippenhall move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

About our fire stopping in Dippenhall

We are commercial sealant applicators, CHAS accredited and a Constructionline member, with CSCS-carded applicators on site. We don’t hold a third-party fire-stopping installer certificate, and we won’t pretend otherwise. We install the specified fire-rated sealant to its tested detail, and our workmanship carries a 12-month guarantee. We work on cable penetrations, service gaps in risers and linear gaps at wall heads, and the failures we’re asked to look at most are service penetrations left open after M&E works and fire stopping installed outside its tested range. For commercial sealant work in Dippenhall, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

Rural conversions around Dippenhall can put new fire-resisting partitions inside older structures. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.

Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Surface by surface

Metal pipes

Metal pipes conduct heat, so their details often call for extra measures along the pipe. We follow whatever the detail requires and flag anything we can’t match.

Linear joints

Joints at the top of partitions may need to move as the slab above deflects. The specified product and backing for that movement are what goes in.

Honest limits

A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be any of the following:

  • Issuing fire ratings or certificates for seals
  • Construction that lacks the fire resistance the seal relies on
  • Large openings beyond what any sealant detail covers

Not sure which it is? You can ring 01277 525 020 or email the details over and we will tell you honestly.

Joints and surfaces we work on

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

Our process

The first thing on site is a walk round with your contact, 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. If others near Dippenhall need work, visits can be combined, which keeps travel down. You will have a fixed quote before work starts.

  1. We read the specification, drawings or penetration schedule you send and raise any questions before we price.
  2. Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
  3. Unsuitable fillers and loose debris are taken out of each opening.
  4. We fit the backing the detail asks for, to the stated depth.
  5. Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
  6. If an opening needs something other than sealant, we tell you instead of improvising.

Getting the site ready

  • Point out parking and an unloading spot
  • Let us know about inductions and permits
  • Tell staff and tenants when we will be in

Advice

Maintenance after handover

For the best life from the joints:

  • Ask which product is in place before decorating
  • Include service cupboards in routine inspections
  • File the specified details where the next contractor can find them
  • Agree the fire-stopping specification before services go in

Don’t patch a fire-rated seal with anything outside its tested detail. Repairs need the same product and detail as the original.

Looking at service areas on a regular cycle pays off. Catching a damaged seal early keeps the fix small compared with dozens found at once.

Service penetrations in Dippenhall buildings

For England, the fire stopping of penetrations is dealt with in Approved Document B. 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. Our part stays the same: the specified product, installed to its tested detail. Dippenhall is about 37 miles from central London. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls.

In a retail centre such as Farnham Retail Park, 2.2 miles east of Dippenhall, any fire-resisting wall between units that is crossed by new services needs sealing to the tested detail. In a hotel such as Farnham House Hotel, which lies south of Dippenhall, new pipework or cabling through bedroom and corridor walls needs sealing with the specified product. At a university such as University for the Creative Arts, 1.2 miles east of Dippenhall, labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work.

Dippenhall is about 2 miles west of Farnham, in Surrey. If you’re looking for fire stopping in Dippenhall, we can help. 379 places across Surrey fall within our area, including Dippenhall. Our Reading page has more on work in that area (17 miles or so).
