Fire stopping for Deepcut sites

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Fire stopping for commercial buildings in Deepcut

Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. We don’t hold a third-party fire-stopping installer certificate and we’d rather say that up front. What we offer is careful installation of the specified sealant to its tested detail, with a 12-month guarantee on our workmanship. If you are dealing with service penetrations left open after M&E works and damaged fire seals in risers and voids, we can put it right, on linear gaps at wall heads, pipe penetrations and small duct penetrations where the tested detail allows alike. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Deepcut is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

In places the size of Deepcut, fire-resisting walls and floors are found in schools, care homes, health centres and mixed-use buildings. Around those penetrations, fire-rated sealant is installed if specified, with depth, backing and gap all as tested.

Work we carry out comes with a 12-month guarantee. If an installation problem shows up, call 01277 525 020 or send photos by email and we’ll arrange a return visit.

Different surfaces, different methods

Metal pipes

Metal pipes conduct heat, so their details often call for extra measures along the pipe, and some details add wrapping or a set length of insulation. If the detail needs something beyond sealant, we tell you.

Cables and cable bundles

New data and power cables are the most common breach we see. We reseal around them to the specified detail, and any bundle too large for sealant alone is flagged.

Penetration seals near Deepcut

Central London is about 29 miles from Deepcut. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls, and the gaps need sealing with the specified product. Deepcut has several hotels close by, all within 2 miles. 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.

Schools such as Sandringham Infant & Nursery School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards. For a hotel such as Lakeside International Hotel (1 mile south-west of Deepcut), penetration seals are worth checking after any refit or services upgrade. Office fit-outs on sites such as Cedar Business Park, 1.8 miles west of Deepcut, add cabling and pipework through fire-resisting walls, and fire-rated sealant goes in where the specification calls for it.

Deepcut is about 1 mile east of Frimley, in Surrey. Commercial clients in Deepcut can call on us for service penetrations, as part of our coverage of Surrey. Across Surrey, 379 places are covered, Deepcut among them. We also cover Reading, around 15 miles from Deepcut.

When something else is needed

Our job is the joint, not everything around it. Sealant alone won’t deal with:

  • Deciding what a wall or floor needs, which belongs to the designer
  • Approving the work on behalf of building control
  • Plastic pipes whose detail calls for a collar or wrap

If you are not sure, just call 01277 525 020 or email drawings and photos and we’ll give you a straight answer.

Where we work in Deepcut

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

On site: what to expect

We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. For a site in Deepcut, we plan so the whole job is done in one go where possible. Photos with rough sizes let us arrive with everything needed.

  1. We ask for the product and detail your designer has specified.
  2. Openings are measured and grouped by detail.
  3. Improvised fillers and failed sealant are removed.
  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. Completed areas are checked with you, with the records agreed when we quoted.

What we need from you

  • Tell us your opening times and when work is allowed
  • Have the specification and drawings to hand
  • Tell us which areas need to stay in use

Related advice

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.

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.

Questions we are asked in Deepcut

Do you work in occupied care homes around Deepcut?

Yes. Care settings are planned area by area, at times agreed with the home. Noise and disruption are kept to a minimum.

Do you seal service penetrations in hotels around Deepcut?

Yes, to the specification and the product’s tested detail. Work is done room by room so the hotel keeps trading; design and sign-off stay with the designer and building control.

Is Deepcut in your area?

Yes. Sites across Deepcut are covered, and the same phone number covers every area.

What if there’s asbestos in the old mastic?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.

Do you seal on top of existing sealant?

No, never. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.

Do you work to architects’ specifications?

Yes. Include it with the drawings when you ask for a quote, and we’ll price the work to it.

What’s the quickest route to a quote?

The quote form is the simplest route, though you can also speak to us on 01277 525 020 or email a schedule or drawings. Include photographs or drawings if you have them.

Commercial clients in Deepcut

If you look after buildings for someone else, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.

We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Deepcut can form part of a wider programme.

Why act early in Deepcut

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, and the right detail can be checked at the time. A failed joint lets water into a building whatever its size. Early resealing avoids the damage that follows a leak.

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.
