Service penetrations in Weston Green buildings

There are a number of hotels within about 2 miles of Weston Green. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal. Weston Green has eight care or nursing homes no more than 2 miles away. Care homes rely on fire-resisting walls and floors, and maintenance work that breaks through them leaves openings to seal.

At a college such as Esher Sixth Form College (less than half a mile north of Weston Green), checking penetration seals after summer M&E works is good practice. At a healthcare site like Molesey Community Hospital, 1.5 miles to the north-west of Weston Green, new services through compartment walls are a constant, and each needs the specified seal.

Fire stopping in Weston Green

Every service that crosses a compartment wall or floor leaves an opening, and that opening needs sealing to hold back fire and smoke. Our part is installing fire-rated and intumescent sealant at those openings and along linear gaps, where the specification calls for it. Each seal follows the manufacturer’s tested detail, not a rule of thumb. If you’re dealing with fire-rated sealant that has cracked or shrunk back and head-of-wall gaps with no fire seal, we can help, whatever the surface. Most enquiries from Weston Green start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

A job near Weston Green is typically planned around one visit, 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 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

Weston Green: questions and answers

How does the removal of BS 476 from Approved Document B affect fire-rated sealing in Weston Green?

From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.

Will you work in a care home in Weston Green without moving residents out?

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 you work to architects’ specifications?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.

Do you need to see the site first?

Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit.

How do I request a quote?

There are four steps: send details, get a quote, we seal, guaranteed. The first step only needs photos and a postcode.

Do your applicators hold CSCS cards?

Yes. We use CSCS-carded applicators, as many construction sites ask for.

Is your workmanship covered by a guarantee?

Yes, for 12 months. If our installation fails in that time, we return and fix it.

Work for main contractors and building owners

We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Sites in Weston Green can sit alongside others in a wider programme across Surrey.

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.

Signs you need fire stopping in Weston Green

Most open service penetrations are left by later work. New cabling, rerouted pipework or a data route drilled through a riser can leave the hole behind. Over a few years of fit-outs, a wall can collect a lot of these.

Most enquiries start with something like this:

  • Expanding foam used as fire stopping
  • Unsealed penetrations discovered above suspended ceilings
  • Penetration schedules that need working through
  • Old intumescent sealant that has split away

Shop fits in centres such as Bentall Centre (to the north-east of Weston Green) can bring new services through fire-resisting walls between units, which then need the specified seal.

What your quote should include

  • Whether primer will be used where the manufacturer specifies it
  • How long is the guarantee, and what does it include?
  • Which product they’ll use, and why it suits the joint
  • Whether old or failed sealant will be cut out, not overlaid

Questions to ask before you appoint anyone

What the job involves on each surface

Small ducts

We seal around ducts only within what the tested detail covers. Dampers and ductwork systems themselves are outside our work.

Linear joints

Head-of-wall joints often have to absorb slab deflection. The specified product and backing for that movement are what goes in, along the full length of the run.

Maintenance after handover

For the best life from the joints:

  • Have penetrations checked while they can still be seen
  • Don’t let anyone top up a fire seal with the wrong product
  • Flag new cables with no seal around them
  • Make fire stopping part of every scope that crosses a fire-resisting wall

Never top up a fire seal with foam, ordinary silicone or filler. A repair should use the original product, installed the same way unless the designer specifies otherwise.

Regular walk-rounds of service areas are worth the time. A cracked or disturbed seal found early is a small job; found late, it can be one of many.

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 we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. Jobs in and around smaller places like Weston Green are typically planned as a single visit, so photographs and measurements up front really help. That way the right products come on the day.

  1. We read the specification, drawings or penetration schedule you send and ask about anything unclear.
  2. Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
  3. Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
  4. We fit the backing the detail asks for, to the stated depth.
  5. Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
  6. If an opening needs something other than sealant, we tell you instead of improvising.

Getting the site ready

  • Agree which areas must stay open
  • Send any specification or drawings in advance
  • Let building users know which areas are affected

Getting a fixed quote

Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To ask for one, speak to us on 01277 525 020 or email drawings and photos.

What affects the price in Weston Green

The price varies from site to site. Expect it to depend on:

  • How much existing material needs removing
  • The total length or number of joints
  • Location, for remote and island sites
  • Backing rod, priming and other preparation

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.

Details that help us quote

A good diagnosis starts with the right details. Tell us:

  • Rough lengths or quantities, or drawings if you have them
  • A wide shot and a close-up of the area
  • Your programme or deadline
  • Asbestos survey details if the building is older

Send us photos, drawings or a joint schedule and a fixed quote comes back to you. If the job needs a look first, we’ll arrange a site visit.
