Fire stopping for Durrants sites

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

Compartments and services around Durrants

Several hotels sit less than 2 miles from Durrants. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close. In England, Approved Document B covers fire stopping of openings and penetrations. 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.

For a building such as St John the Baptist, new heating or data runs are the usual reason penetrations need sealing. Schools such as Havant Academy often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards. Tenant changes at parks like Dunsbury Hill Business Park (to the west of Durrants) bring new data and services, and openings through fire-resisting walls need the specified seal.

Durrants is about 2 miles north-east of Havant, in Hampshire. Businesses, contractors and managing agents in Durrants use us for work on service penetrations, as part of our coverage of Hampshire. We work across 723 places in Hampshire, large and small. Our Portsmouth page has more on work in that area.

Commercial sites across PO9 are covered for service penetrations. If your site is on Whichers Close, Whichers Gate Road and Durrants Road or close by, we can quote for service penetrations. Nearby places we also cover include Rowlands Castle (1 mile north), Leigh Park (1 mile south-west), Havant (2 miles south-west), Denvilles (2 miles south) and Westbourne (2 miles south-east). A short drive away, we cover Gosport (10 miles south-west), Fareham (10 miles west), Horndean (3 miles north-west), Hedge End (15 miles west), Waterlooville (3 miles west) and Petersfield (9 miles north).

Fire stopping in Durrants, done properly

Where pipes, cables and other services cross a compartment wall or floor, the opening around them has to be closed so fire and smoke can’t move between compartments. Our part is installing fire-rated and intumescent sealant at those openings and along linear gaps, where the specification calls for it. We work to the product’s tested detail for every seal rather than guesswork. Site teams most often ask us about seals disturbed by maintenance and left open and openings found when ceilings come down for a refit, across small duct penetrations where the tested detail allows, joints between fire-resisting walls and floors and cable penetrations. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Durrants is the same: the right product in a properly prepared joint.

For a smaller site near Durrants, we plan to do all the penetrations in one go, with the specification and photographs sent in advance. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.

We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and if something we did falls short, we return to it.

After the work

Regular inspection catches problems early. In particular:

  • Leave fire sealant to cure fully before covering it
  • Make fire stopping part of every scope that crosses a fire-resisting wall
  • Flag new cables with no seal around them
  • Look above ceilings when tiles are lifted for other jobs

After every round of M&E works, check that the openings created have been sealed. A short check at the end of each job saves a long hunt later.

Ask every contractor who works in risers or voids to report openings they create. Small habits like this stop openings building up.

Work for main contractors and building owners

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sites in Durrants can sit alongside others in a wider programme.

Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.

What we can’t put right

Honesty saves time and money. New sealant won’t cure:

  • Openings that need collars, wraps, batts or boards rather than sealant
  • Approving the work on behalf of building control
  • Designing or specifying fire stopping, which sits with the designer or fire engineer

If in doubt, call 01277 525 020 or email a schedule or drawings and we’ll say what we think before you book.

Where we work in Durrants

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

Why deal with it now?

Open service penetrations matter on ordinary days, not just in a fire: smoke, noise and draughts pass through them every day. Sealing them to the specified detail deals with the fire risk first, and the other benefits follow. Halls, stores and units around places like Durrants may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.

FAQs: Durrants

Is Durrants too far out for you?

Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Do you work on fire-rated sealing in hotels in Durrants?

Yes. We install fire-rated and intumescent sealant where it is specified. We match the product to the wall or floor and the services, and say if something other than sealant is needed.

How long does a job like this take?

The duration is planned around your programme and the access we’re given. We will give you an estimate of time on site when we quote.

Can you send site paperwork?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.

How soon can the area be used again?

The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.

How do we ask for a quote?

You can use the quote form on this site; alternatively, speak to us on 01277 525 020 or send photos by email. Photos, drawings or a joint schedule help us quote quickly.

When can you be on site?

Mention the site’s hours and access windows in your enquiry, and we will schedule the work to suit. You can reach the office between 8am and 5pm, Monday to Friday.

From enquiry to sign-off

Before we leave any area, the masking comes off, the area is cleaned and every joint is checked with your site contact. Where the sealant needs time to cure before use, we tell you and sign the area. If others near Durrants need work, visits can be combined. You will have a fixed quote before work starts.

  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. 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. 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.

Before we start on site

  • Let us know about inductions and permits
  • For older buildings, check the asbestos register before work
  • Have the specification and drawings to hand

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. For smaller jobs, photos and a description will do.

Advice

What sets the cost

What shapes the price:

  • Distance, for remote addresses
  • Whether the work must be split into stages
  • The size and state of each joint
  • Whether old sealant has to be cut out first

No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

What we need to price the job

Good information means a firmer quote. Helpful details to send:

  • Anything awkward about access or site hours
  • Rough lengths or quantities, or drawings if you have them
  • The postcode of the building
  • Specification clauses that apply

Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. To get it moving, ring 01277 525 020 or email drawings and photos.
