How we handle fire stopping in Aaron's Hill

No fire sealant works on its own: the evidence covers a specific product, wall or floor type, service, gap, depth and backing. We match each opening to that detail before any sealant goes in. Most enquiries involve openings left by services added after handover and head-of-wall gaps with no fire seal, across joints between fire-resisting walls and floors, pipe penetrations and linear gaps at wall heads. Whoever orders the work in Aaron's Hill, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.

In places the size of Aaron's Hill, fire-resisting walls and floors are found in schools, care homes, health centres and mixed-use buildings. Specified fire-rated sealant goes around new services there, built to match the manufacturer’s detail.

A 12-month guarantee applies to all our work in Surrey. Should something we installed fail, call the office on 01277 525 020 or email the details over and we’ll come back to it.

Where services cross fire walls in Aaron's Hill

Aaron's Hill lies roughly 32 miles out 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. Aaron's Hill has several hotels close by, all within 2 miles. 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.

For an estates team at a campus like University of Surrey - Manor Park Campus, which lies north of Aaron's Hill, summer M&E works are typically followed by a round of penetration sealing. Hospital estates such as Milford Hospital, 1.1 miles to the south of Aaron's Hill, are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail. Office fit-outs on sites such as Godalming Business Centre, 1.2 miles to the east of Aaron's Hill, add cabling and pipework through fire-resisting walls, and fire-rated sealant goes in where the specification calls for it.

Aaron's Hill is about 1 mile west of Godalming, in Surrey. Looking for fire stopping in Aaron's Hill? We can help, as we do across Surrey. 379 places across Surrey fall within our area, including Aaron's Hill. Reading is covered too, around 24 miles from Aaron's Hill.

When something else is needed

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

  • Writing the fire-stopping specification
  • Reviewing a building’s overall fire safety
  • Issuing fire ratings or certificates for seals

If in doubt, speak to us on 01277 525 020 or email us and we’ll say what we think before you book.

Joints and surfaces we work on

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

Why deal with it now?

It is cheaper to seal service penetrations as each services package finishes than to come back for them later. While the area is still open, every opening is easy to see and reach, and the right detail can be checked at the time. For buildings in places like Aaron's Hill, one well-planned visit beats several small ones, so it’s worth dealing with every failing joint at once.

We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote and we’ll price your job on its own details.

Why us?

  • Fixed quotes based on photographs, drawings or a visit
  • Constructionline member for supplier checks
  • One contact handling all your sites
  • CHAS accredited

From enquiry to sign-off

We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. If neighbouring businesses or buildings around Aaron's Hill need work too, visits can be combined. Tell us your site hours and we’ll plan around them.

  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. We fit the backing the detail asks for, to the stated depth.
  5. We apply the specified sealant to the depth and around the services as the detail shows.
  6. Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.

What we need from you

  • Explain the parking and delivery arrangements
  • Send your site hours and access windows
  • Agree which areas must stay open

Advice

How the job changes by surface

Metal pipes

Sealant details often cover copper and steel pipework. Pipe diameter, annular gap, sealant depth and any pipe insulation all have to match the detail, so we check each one.

Risers and ceiling voids

Risers and ceiling voids hold most of a building’s service penetrations. Access to these areas is planned with you in advance.

After the work

After handover, these steps help:

  • Put resealing into every M&E and fit-out package
  • Keep product data and details in the fire safety file
  • Get seals inspected before ceilings and boxing close
  • Foam or ordinary sealant is never a fire-seal repair

After the work, brief anyone else working in the area that the openings are now sealed. Any seal cut back for a new service needs reinstating to its tested detail.

The simplest way to keep compartment walls intact is to plan fire stopping into every job that crosses them. That way the opening is sealed while the trade and access are still there.

What sets the cost

These are the things that shape the price:

  • Which sealant the job calls for
  • How much existing material needs removing
  • How much there is to seal
  • Induction, permit and paperwork requirements

The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we will explain how it’s made up.

Details that help us quote

Good information means a firmer quote. Helpful details to send:

  • Any specification or named product
  • Whether the building will be occupied during the work
  • When you need the work done
  • The postcode of the building

Aaron's Hill: questions and answers

Is Aaron's Hill off your patch?

No. Small places get the same service as large ones. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Does your area include sites such as Godalming Business Centre, near Aaron's Hill?

Yes. We cover Aaron's Hill and the area around it, including industrial estates, business parks and retail parks such as Godalming Business Centre. To start, just speak to us on 01277 525 020 or send photos by email with the unit, the joints involved and your access times.

Do you design or specify fire stopping?

No. Deciding what is needed sits with the designer, fire engineer and building control. Our role is installing what they specify, to the product’s tested detail.

Can one quote cover more than one building?

Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.

Do the same rules apply to fire stopping in Scotland?

Our work covers Greater London, the South East and every Scottish council area. In Scotland, clause 2.1.14 of the non-domestic Technical Handbook says service penetrations should keep at least the fire resistance of the wall or floor, with proprietary products tested for the end use.

Is it fine to apply new sealant on top of old?

No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.

Is the work guaranteed?

Yes. Our workmanship is backed for 12 months on every job.
