Fire stopping near Lower Green

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Why it’s worth doing now in Lower Green

An open or wrongly sealed service penetration lets fire and smoke reach the next compartment much sooner than the building was designed for. Putting it right is usually a modest job when the openings are accessible. Left until ceilings are closed or a tenant moves in, the same work costs more access and more disruption. One visit to deal with every failing joint makes more sense than several trips to a place like Lower Green, rather than one at a time. Photos of every joint help us quote for the whole job.

The specified product makes a difference, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site rules also count.

What you get with us

  • Joints cleaned back to sound surfaces
  • A Constructionline member, so easy to vet
  • Fixed quotes based on photos, drawings or a visit
  • Fully insured, including public liability cover

Fire stopping in Lower Green, done properly

Opened ceilings and riser doors often reveal service openings nobody sealed. If a specification already covers those walls and floors, we can reseal to it, matching the product and detail it names. Where there isn’t one, the designer or fire engineer needs to set one first. If you are dealing with head-of-wall gaps with no fire seal and service penetrations left open after M&E works, we can help. Most enquiries from Lower Green start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.

For a smaller site near Lower Green, we plan to do all the penetrations in one go, with the specification and photographs sent in advance. Design and sign-off belong to the designer or building control; we install what’s specified.

Work we carry out comes with a 12-month guarantee. Should something we installed fail, give us a call on 01277 525 020 or send photos by email and we will come back to it.

After the work

Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:

  • Ask the designer to confirm details early on refits
  • Treat an open penetration as a priority repair
  • Have penetrations checked while they can still be seen
  • Brief every trade that openings they make must be sealed

Give the sealant its full cure time before ceilings, boxing or decoration go over it. Not every fire-rated product can be painted, and the data sheet says which.

A simple record of seal locations and products helps. It tells the next contractor exactly what to reinstate, and it helps at inspections.

Owners, agents and contractors

For main contractors, we work as the sealant subcontractor. We work to your programme, your specification and your site rules.

If you look after buildings for someone else, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.

What we can’t put right

Sealant solves a lot, but not everything, and we’re upfront when that’s the case. It won’t fix:

  • Fire doors, dampers or other fire safety equipment
  • Issuing fire ratings or certificates for seals
  • Large openings beyond what any sealant detail covers

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

Surfaces we seal

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

Compartment walls and floors in Lower Green

The area within 2 miles of Lower Green holds several hotels. 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. Lower Green is about 14 miles from central London. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls.

In a hotel such as The Bear Hotel, which lies south of Lower Green, new pipework or cabling through bedroom and corridor walls needs sealing with the specified product. For a hospital such as Molesey Community Hospital, 1.1 miles to the north of Lower Green, penetration sealing is normally phased ward by ward, with infection-control rules agreed first. At a university such as Kingston University Penrhyn Road Campus, 3.1 miles north-east of Lower Green, labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work.

Lower Green is about 1 mile north of Esher, in Surrey. We send applicators to Lower Green for service penetrations, handled exactly as we handle every other area. Lower Green is one of 379 places in Surrey on our list. Our London page has more on work in that area.

Postcode districts covered here: KT10 and KT12 for service penetrations.

Bigger towns within reach include Guildford (13 miles south-west), Woking (10 miles south-west), Epsom (5 miles south-east), Redhill (13 miles south-east), Ewell (5 miles south-east) and Egham (8 miles north-west).

Questions we’re asked in Lower Green

Is Lower Green too far out for you?

No. Places such as Lower Green are covered as much as the big towns. We cover Greater London and the counties of the South East. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Can work in a care setting near Lower Green go ahead while residents are there?

Yes. We agree rooms and times with the manager and work a few areas at a time. Noise and disruption are kept to a minimum.

Do the same rules apply to fire stopping in Scotland?

Our work covers Greater London, the South East and every Scottish council area. Scotland’s non-domestic Technical Handbook, clause 2.1.14, expects service penetrations to be fire stopped to at least the wall or floor’s fire resistance, with proprietary products tested for the end use.

Do you have public liability insurance?

Yes. Our insurance certificate can be sent alongside the quote.

Can the sealant be colour-matched?

It depends on the product. Some ranges are wide, others limited, so the available colours are confirmed with the quote.

Will you just go over the old sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.

Can you handle several sites?

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

Surface by surface

Small ducts

We seal around ducts only within what the tested detail covers. The ductwork, its supports and any dampers are for the ductwork contractor.

Risers and ceiling voids

Voids hide a lot of unsealed openings. We work through the areas on your schedule methodically and tell you about openings outside the list.

From enquiry to sign-off

Diagnose, treat, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. Rural sites near Lower Green may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.

  1. We read the specification, drawings or penetration schedule you send.
  2. On site, each opening is checked against the tested detail it is meant to follow.
  3. Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
  4. Mineral wool or other backing goes in wherever the detail asks.
  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

  • Make sure the joints can be reached
  • Tell us which areas need to stay in use
  • Confirm the product named in the specification
