Fire stopping for businesses in Stanwell Moor

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

How we handle fire stopping in Stanwell Moor

On a fit-out or refurbishment, we follow the services contractors floor by floor. To price a package, ring 01277 525 020 or send photos by email with the schedule or marked-up drawings. Tell us what records you need and we will confirm with the quote. Most enquiries involve expanding foam used as fire stopping and head-of-wall gaps with no fire seal, across cable penetrations, linear gaps at wall heads and pipe penetrations. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Stanwell Moor it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

For a smaller site near Stanwell Moor, we plan to do all the penetrations in one go, so send the specification and photos first. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.

Whoever the client is, the cover is the same: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

FAQs: Stanwell Moor

Can you work at a site such as Skyport Industrial Estate, by Stanwell Moor?

Yes. We cover Stanwell Moor and the area around it, including industrial estates, business parks and retail parks such as Skyport Industrial Estate. Send details of the unit and the work through our quote form for a quick quote.

Is Stanwell Moor too far out for you?

Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Will you just go over the old sealant?

No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.

Which sealant will you use?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

How do you deal with asbestos in old sealant?

Managing asbestos is the dutyholder’s responsibility, so we’ll ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.

Do you design or specify fire stopping?

No, we don’t design fire stopping. Once you have a specification, we can price and install the sealant elements of it.

Are you insured?

Yes. We are fully insured, including public liability cover.

What affects the price in Stanwell Moor

A fixed quote reflects the actual work. It takes account of:

  • Induction, permit and paperwork requirements
  • How much there is to seal
  • Which sealant the job calls for
  • Whether old sealant has to be cut out first

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.

What to include in your enquiry

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

  • A wide shot and a close-up of the area
  • Rough lengths or quantities, or drawings if you have them
  • Whether an asbestos survey exists
  • Where the site is, with the postcode

Pricing a project or setting a maintenance budget? Send the scope and any drawings, and we will return a fixed quote you can plan around. For a chat about it beforehand, call the office on 01277 525 020 or email drawings and photos.

For managing agents and facilities managers

Main contractors use us as their sealant subcontractor. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.

Whether you are a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.

What we can’t put right

We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:

  • Gaps in walls that were never built as compartment walls
  • Reviewing a building’s overall fire safety
  • Signing off or certifying a building’s fire stopping

If you’re not sure, just call the office on 01277 525 020 or email us and we will give you a straight answer before you book.

Where we work in Stanwell Moor

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

How the job changes by surface

Small ducts

Ducts are only sealed with sealant where the detail allows it. Dampers and ductwork systems themselves are outside our work.

Risers and ceiling voids

Service risers and the voids above ceilings are where openings collect. Access to these areas is planned with you in advance.

Diagnose, treat, 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 Stanwell Moor are typically planned as a single visit, so we ask for photographs and rough sizes first. That way the right products come on the day.

  1. First we go through the drawings, schedule or specification for the seals and raise any questions before we price.
  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.

What we need from you

  • Share your working hours and any access restrictions
  • Let us know about inductions and permits
  • Send any specification or drawings in advance

Request a quote

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, speak to us on 01277 525 020 or send photos by email.

Compartments and services around Stanwell Moor

Stanwell Moor lies roughly 18 miles out from central London. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls, and the gaps need sealing with the specified product. For England, the fire stopping of penetrations is dealt with in Approved Document B. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. Either way, we install the specified product to its tested detail.

Hotels like The Stanwell Hotel, 0.9 miles south-east of Stanwell Moor, are refurbished in phases, and each phase can open up compartment walls. Where a unit on an estate such as Skyport Industrial Estate, which lies north-east of Stanwell Moor, has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail.

Signs you need fire stopping in Stanwell Moor

Fire stopping can get squeezed at the end of a programme, or done by whoever is on site. That is how unsuitable products and improvised details end up in compartment walls and later need putting right.

Clients usually get in touch after noticing one or more of the following:

  • Fire sealant pulled out of the opening
  • Snag lists that include open service penetrations
  • Service penetrations left open after M&E works
  • Non-fire-rated filler around services

At a university such as Royal Holloway University, which lies south-west of Stanwell Moor, labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work.
