Fire stopping around Hamsey: points for this area

A number of hotels sit less than 2 miles from Hamsey. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal. Hamsey is about 42 miles from central London. Office refits around the commuter belt bring new cabling through fire-resisting walls, and the gaps need sealing with the specified product.

At a healthcare site like Lewes Victoria Hospital (1.5 miles south of Hamsey), new services through compartment walls are a constant, and each needs the specified seal. At a university such as University of Sussex, which lies south-west of Hamsey, labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work.

Hamsey is about 1 mile north of Lewes, in East Sussex. We cover commercial sites throughout Hamsey, for single jobs and planned programmes alike. We work across 308 places in East Sussex, large and small. Our Brighton page has more on work in that area, about 7 miles away.

How we handle fire stopping in Hamsey

Fire-rated sealant suits many small service penetrations: copper and steel pipes, cables and some small ducts where the tested detail allows. Other openings need collars, wraps, batts, pillows or boards. We use sealant where it is the specified product, and we tell you when a detail calls for something else. Most enquiries involve seals that don’t match their tested detail and builders’ foam or ordinary silicone in compartment walls, on service gaps in risers, pipe penetrations and cable penetrations. Searching for sealant specialists in Hamsey? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.

For a smaller site near Hamsey, 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.

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.

Different surfaces, different methods

Risers and ceiling voids

Voids hide a lot of unsealed openings. We work through the areas on your schedule methodically, and note anything we find that isn’t on it.

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.

Our process

Occupied buildings need a little choreography. The work area is signed and kept contained, with routes through the building left open and move on in phases so staff and visitors can carry on around us. For a building around Hamsey, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.

  1. First we confirm the product and tested details named in the specification.
  2. Openings are measured and grouped by detail.
  3. Old or wrong materials are cut out.
  4. Mineral wool or other backing is fitted where required.
  5. We gun the sealant in to the specified depth around each service and tool it.
  6. We walk the completed areas with you and confirm the records agreed at quote stage.

Preparing the site

  • Share your working hours and any access restrictions
  • Move anything stored against the joints
  • Send asbestos survey details if the building is pre-2000

Ask for a quote

General trades versus a specialist

Redoing a failed joint typically costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

Hamsey: questions and answers

Will you take on work at estates like Malling Industrial Estate, close to Hamsey?

Yes. We cover Hamsey and the area around it, including industrial estates, business parks and retail parks such as Malling Industrial Estate. Photos and a short description are enough for a first look.

Will you plan work around the academic year at somewhere like University of Sussex?

Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. Let us know which documents your site asks for, and we will confirm them alongside the quote.

Can you handle several sites?

Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.

When can the area be used after sealing?

Curing time varies by product, and we confirm it on the day.

What about RAMS and site documents?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.

How much does the work cost?

Every job gets its own fixed quote. For yours, call 01277 525 020 or email a schedule or drawings.

Do you work to architects’ specifications?

Yes. The specification and the manufacturer’s installation guidance are what we work to.

How the quote is worked out

To price the job, we consider:

  • Quantities, in metres or numbers
  • How accessible the joints are
  • Distance, for remote addresses
  • Which sealant the job calls for

The price depends on the quantity of joints, how much old material needs removing and how the joints are reached. Call for a quote once you have the details.

Before you send an enquiry

Good information means a firmer quote. When you get in touch, include:

  • Clear photos of the problem areas
  • Where the site is, with the postcode
  • Any specification or named product
  • How the joints are reached, and at what height

Every quote starts with the facts: the joints involved, quantities, access and the product called for. Send what you have, and we will arrange a site visit if anything is unclear.

When to call us in Hamsey

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.

Site and facilities staff are often the first to spot these:

  • Fire-stopping items raised at inspection or handover
  • Seals that don’t match their tested detail
  • Fire-rated sealant that has cracked or shrunk back
  • Fire seals cut back for extra cables and never reinstated

Where a unit on an estate such as Malling Industrial Estate, which lies south-east of Hamsey, has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail.
