Fire stopping for Hiltingbury sites

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

How we handle fire stopping in Hiltingbury

Most of our fire stopping work happens after the building is up. Each new cable, pipe or data route cut through a fire-resisting wall leaves an opening behind. Those on your schedule are closed with the specified product. If you have head-of-wall gaps with no fire seal and damaged fire seals in risers and voids, we can help. For commercial sealant work in Hiltingbury, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

Converted and extended buildings around places like Hiltingbury can mix old and new construction, so the wall or floor a service passes through isn’t always what the drawings assume. We match the product to the substrate and service, and say so if a collar, wrap or batt is the specified item.

Our workmanship is guaranteed for 12 months. If a joint we sealed fails because of how it was installed, we come back and put it right.

Compartments and services around Hiltingbury

Approved Document B is the English guidance that covers fire stopping around openings and penetrations. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail. There are a number of hotels within about 2 miles of Hiltingbury. In hotels, bedroom and corridor walls are typically fire-resisting, so services added in a refit need sealing with the specified product.

Colleges such as Barton Peveril Sixth Form College (2.7 miles south of Hiltingbury) add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product. Campus buildings at universities such as University of Southampton (to the south of Hiltingbury) see constant changes to data and services, and fire-rated sealant goes in around new penetrations where it is specified.

What the job involves on each surface

Risers and ceiling voids

Risers and ceiling voids hold most of a building’s service penetrations. Access to these areas is planned with you in advance, including keys, permits and any isolations.

Cables and cable bundles

Data cabling added after handover is a regular cause of open service penetrations. We reseal around them to the specified detail, and we tell you if the bundle exceeds what sealant covers.

Why act early in Hiltingbury

It is cheaper to seal service penetrations as each services package finishes than to come back for them later. Openings are visible, access is open and nothing has to be taken down and each detail can be checked as we go. In a smaller place such as Hiltingbury, getting a contractor back for a second visit takes time, so it’s worth dealing with every failing joint at once.

Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

Hiltingbury: questions and answers

Do you cover business parks and estates near Hiltingbury, such as Omega Enterprise Park?

Yes. Our area takes in Hiltingbury and its surroundings, with estates and business parks such as Omega Enterprise Park included. A few photographs and the unit address let us price the work.

How does the move away from BS 476 affect penetration seals in Hiltingbury?

References to BS 476 classes are being removed from Approved Document B from 2 September 2029, after which BS EN 13501-2 classification is the route, subject to transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.

Can the sealant be colour-matched?

It depends on the product. Some ranges are wide, others limited, so we will confirm the colours available for the specified product with the quote.

Can you handle several sites?

Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.

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

No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.

Do you have public liability insurance?

Yes. We are fully insured, and the certificate can go with your quote.

Do you hold CHAS accreditation?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

Keeping the joints sound

A few simple habits keep the new joints working:

  • Look above ceilings when tiles are lifted for other jobs
  • Treat an open penetration as a priority repair
  • Record which product was used where
  • Settle who seals which penetrations at the start of a project

Give the sealant its full cure time before ceilings, boxing or decoration go over it. Not every fire-rated product can be painted, so check the product data first.

The simplest way to keep compartment walls intact is to plan fire stopping into every job that crosses them. Then the seal goes in while the area is open instead of being left for someone else.

How a job runs

We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. For a site in Hiltingbury, we plan so the whole job is done in one go where possible. Clear photographs and measurements help us bring the right products.

  1. We ask for the product and detail your designer has specified.
  2. Openings are measured and grouped by detail.
  3. Old or wrong materials are cut out.
  4. Where the detail needs backing, it goes in at the stated depth.
  5. We gun the sealant in to the specified depth around each service and tool it.
  6. Completed areas are checked with you, with the records agreed when we quoted.

Getting the site ready

  • Confirm the product named in the specification
  • Tell us which areas need to stay in use
  • Share your working hours and any access restrictions

Advice

Commercial clients in Hiltingbury

We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Hiltingbury can form part of a wider programme.

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

Do you need fire stopping in Hiltingbury?

Fire stopping can get squeezed at the end of a programme, or done by whoever is on site. That is when untested combinations creep in, which then have to be put right.

Most enquiries start with something like this:

  • Hidden openings found during inspections
  • Unsealed openings around new pipes and cables
  • Fire seals cut back for extra cables and never reinstated
  • Expanding foam used as fire stopping

Tenant changes at parks like Omega Enterprise Park, 1.1 miles to the south of Hiltingbury, bring new data and services, and openings through fire-resisting walls need the specified seal.
