About our fire stopping in Chilgrove

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. Site teams most often ask us about service penetrations left open after M&E works and fire sealant pulled out of the opening, across small duct penetrations where the tested detail allows, pipe penetrations and linear gaps at wall heads. Whether you call it commercial sealant work, mastic application or joint sealing, in Chilgrove it comes down to the same thing: the right product in a properly prepared joint.

Smaller places such as Chilgrove still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.

We stand by our work with a 12-month guarantee. That covers our preparation and application.

From enquiry to sign-off

At the end of each section, 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. Jobs in and around smaller places like Chilgrove are normally planned as a single visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

  1. We ask for the product and detail your designer has specified.
  2. We sort the openings by the detail each one needs.
  3. Old or wrong materials are cut out.
  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.

Preparing the site

  • Tell staff and tenants when we’ll be in
  • Send asbestos survey details if the building is pre-2000
  • Tell us which areas need to stay in use

Ask for a quote

Let us know the site, the scope and your timescale, and we will put a fixed quote together. The easiest way is to call the office on 01277 525 020 or send photos by email.

What happens if it’s left?

The longer openings stay, the more there tend to be: every new cable or pipe adds another. Keeping on top of it after each round of works keeps the job small and avoids a much larger catch-up later. Around Chilgrove, it’s better to renew all the failing joints at once. Send photographs of each area and we will quote for the lot.

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

For managing agents and facilities managers

If you look after buildings for someone else, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.

Building owners and managing agents use us on sealant work across single buildings or whole portfolios around Chilgrove. Several sites can go on one quote, so there’s one set of paperwork to deal with.

Fire-rated sealing for Chilgrove buildings

Central London is about 51 miles from Chilgrove. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls. In England, Approved Document B covers fire stopping of openings and penetrations. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. Our part stays the same: the specified product, installed to its tested detail.

For a site team at a college like West Dean College of Arts and Conservation (1.7 miles south-east of Chilgrove), fire-rated sealing is best scheduled after the summer works.

Chilgrove is about 6 miles north of Chichester, in West Sussex. We send applicators to Chilgrove for service penetrations. Chilgrove is one of 373 places in West Sussex on our list for service penetrations. For work in that direction, see our Portsmouth page (14 miles or so).

We cover the PO18 postcode districts. We also cover East Marden (2 miles west), Didling (3 miles north), Elsted (4 miles north), Compton (4 miles west) and Ingrams Green (4 miles north) for service penetrations. A short drive away, we cover Bognor Regis (10 miles south-east), Chichester (6 miles south), Selsey (13 miles south), Littlehampton (14 miles south-east), Rustington (15 miles south-east) and Portfield (6 miles south).

Landmarks near Chilgrove

Nearby you’ll also find Chichester Centre (5.2 miles south) and Museum of Gardening (1.7 miles south-east). The countryside around Chilgrove includes Kingley Vale National Nature Reserve and Bow Hill.

Chilgrove: questions and answers

Do you take on work at healthcare sites like Chichester Centre?

Yes, provided the work is planned with the site’s estates team. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Is a smaller place like Chilgrove outside your area?

Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

How long will the new sealant last?

There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.

How do you deal with asbestos in old sealant?

Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.

Do you take on multi-site work?

Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.

How many days will you need on site?

The duration is planned around your programme and the access we’re given. You will have an expected duration with the quote.

Is any job too small?

Small jobs are welcome alongside larger packages. Photos and a description are enough to start.

Common problems we fix in Chilgrove

A common fault is a product that was never fire-rated in the first place: builders’ foam or ordinary silicone used to fill a hole. It may look closed, but it has no tested fire performance in that position.

Most enquiries start with something like this:

  • Fire stopping installed outside its tested range
  • Snag lists that include open service penetrations
  • Openings left by services added after handover
  • Hidden openings found during inspections

Wherever services are added at a hospital such as Chichester Centre, 5.2 miles to the south of Chilgrove, the compartment line has to be made good with the specified product.

Comparing quotes

  • Do they follow the manufacturer’s priming guidance?
  • What the guarantee covers, and for how long
  • How the existing material will be dealt with
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?

Questions to ask before you appoint anyone

Doing it in-house

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

What sealant work can’t fix

Part of a good diagnosis is knowing where sealant stops. You’ll hear from us if the cause turns out to be any of the following:

  • Openings that need collars, wraps, batts or boards rather than sealant
  • Writing the fire-stopping specification
  • Construction that lacks the fire resistance the seal relies on

If in doubt, phone 01277 525 020 or send details through our quote form and we will say what we think.
