Fire stopping for businesses in Aston Clinton

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

On site: what to expect

At the end of each section, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. For a site in Aston Clinton, we plan so the whole job is done in one go where possible. Photos with rough sizes let us arrive with everything needed.

  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. Unsuitable fillers and loose debris are taken out of each opening.
  4. Mineral wool or other backing goes in wherever the detail asks.
  5. Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
  6. Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.

Before we start on site

  • Point out any areas we must not close
  • Send any specification or drawings in advance
  • Tell staff and tenants when we will be in

About our fire stopping in Aston Clinton

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. If the detail calls for something other than sealant, we say so rather than force sealant into it. If you are dealing with openings found when ceilings come down for a refit and non-fire-rated filler around services, we can put it right, on service gaps in risers, pipe penetrations and cable penetrations alike. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Aston Clinton, that means joint design, primers and backing rod as standard.

Converted and extended buildings around places like Aston Clinton 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.

Work we carry out comes with a 12-month guarantee. Should something we installed fail, phone 01277 525 020 or email drawings and photos and we will come back to it.

What we’re called out for in Aston Clinton

Plenty of openings were simply never closed. Inspections, refurbishments and ceiling access normally bring them to light.

If one of these sounds familiar, it’s time for a closer look:

  • Snag lists that include open service penetrations
  • Fire seals cut back for extra cables and never reinstated
  • Builders’ foam or ordinary silicone in compartment walls
  • Openings found when ceilings come down for a refit

Hotels like West Lodge Hotel, less than half a mile to the south-east of Aston Clinton, are refurbished in phases, and each phase can open up compartment walls.

What your quote should include

  • Are they CHAS accredited or on Constructionline?
  • Can the work be phased to keep areas open?
  • Whether their applicators hold CSCS cards
  • What level of public liability insurance do they hold?

Our contractor checklist

Your questions answered

Is Aston Clinton off your patch?

No. Small places get the same service as large ones. We work across Greater London and the South East. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.

Is hospital work, at somewhere like Stoke Mandeville Hospital, something you do?

Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Can you fire stop behind the services contractors?

Yes, where there is a specification for those walls and floors. Openings left by new services are among the most common jobs we see.

How do we ask for a quote?

You can use the quote form on this site; alternatively, call 01277 525 020 or send details through our quote form. Include photographs or drawings if you have them.

When is resealing likely to be due?

It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.

Can you work to our specification?

Yes. Send it with your enquiry, and we’ll price the work to it.

Do you seal on top of existing sealant?

No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.

Compartments and services around Aston Clinton

Aston Clinton has a number of hotels close by, all within 2 miles. In hotels, bedroom and corridor walls are typically fire-resisting, so services added in a refit need sealing with the specified product. Aston Clinton is about 34 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.

Office fit-outs on sites such as Aesop Business Park (0.6 miles north of Aston Clinton) add cabling and pipework through fire-resisting walls, and fire-rated sealant goes in where the specification calls for it. Halls and meeting rooms at places like St Michael and All Angels Church sometimes gain new services, and any compartment wall crossed needs the specified seal.

Cost factors for service penetrations

Sealant work doesn’t have a standard rate, because every site is different. What we look at:

  • Which sealant the job calls for
  • The total length or number of joints
  • Phasing around occupants
  • The size and state of each joint

We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote.

What to include in your enquiry

A few photographs plus some basic facts will normally do. Please tell us:

  • Clear photos of the problem areas
  • The postcode of the building
  • Your programme or deadline
  • Whether the building will be occupied during the work

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. For smaller jobs, photos and a description will do.

What we can’t put right

A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be any of the following:

  • Reviewing a building’s overall fire safety
  • Gaps in walls that were never built as compartment walls
  • Large openings beyond what any sealant detail covers

Not sure which it is? You can ring 01277 525 020 or send details through our quote form and we will tell you honestly.

Surfaces we seal

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

Surface by surface

Plastic pipes

Waste and drainage pipes through floors are a frequent case. Whether sealant alone is acceptable depends entirely on the tested detail, and we will never swap a specified collar for sealant.

Masonry and concrete

Core-drilled holes are neat; broken-out ones rarely are. Each gap is measured where it is widest against the detail’s limits, and any outside it are raised with you.

For managing agents and facilities managers

We work for building owners and managing agents on everything from one building to a spread of sites around Aston Clinton. Several sites can go on one quote, which keeps the paperwork simple.

We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Sites in Aston Clinton can sit alongside others in a wider programme across Buckinghamshire.
