Fire stopping near Dawesgreen

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

Should maintenance staff do it?

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

About our fire stopping in Dawesgreen

On a fit-out or refurbishment, we follow the services contractors floor by floor. To price a package, speak to us on 01277 525 020 or send details through our quote form with the schedule or marked-up drawings. Tell us what records you need and we’ll confirm with the quote. We work on pipe penetrations, linear gaps at wall heads and joints between fire-resisting walls and floors, and what we are called in for most is hidden openings found during inspections and fire-stopping items raised at inspection or handover. For commercial sealant work in Dawesgreen, you deal with one contact from quote to sign-off, whether it’s one building or several.

Rural conversions around Dawesgreen can put new fire-resisting partitions inside older structures. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.

A 12-month guarantee applies to all our work in Surrey. If an installation problem shows up, speak to us on 01277 525 020 or send details through our quote form and we’ll arrange a return visit.

Leave it or put it right?

An improvised seal can look finished while offering no tested performance. Correcting it means cutting it out and starting again with the specified product, and doing it once, properly, is cheaper. For buildings around smaller places like Dawesgreen, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote and we will explain how it’s made up.

Common questions from Dawesgreen clients

Is a hospital such as East Surrey Hospital somewhere you can work?

Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Can you work at a site such as Chesterfield Business Park, by Dawesgreen?

Yes, sites like Chesterfield Business Park are within our area, along with the rest of Dawesgreen. To start, just call the office on 01277 525 020 or use the quote form with the unit, the joints involved and your access times.

Are you insured?

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

Can you quote from photographs?

That depends on the size and complexity of the job. Straightforward work can often be priced from photos and measurements, and bigger or more complex jobs usually get a visit.

How do you deal with asbestos in old sealant?

Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.

Does weather matter for sealant work?

For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.

Can one quote cover more than one building?

Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.

Service penetrations in Dawesgreen buildings

In England, Approved Document B covers fire stopping of openings and penetrations. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. Our part stays the same: the specified product, installed to its tested detail. Dawesgreen lies roughly 21 miles out from central London. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls, and the gaps need sealing with the specified product.

Tenant changes at parks like Chesterfield Business Park, 2.4 miles to the north-east of Dawesgreen, bring new data and services, and openings through fire-resisting walls need the specified seal. In a building such as Church of St Bartholomew, any service penetration through a fire-resisting wall should be sealed to the specified detail. Theatres, wards and plant rooms at sites like East Surrey Hospital (to the east of Dawesgreen) all have compartment walls crossed by services.

Dawesgreen is about 3 miles south-west of Reigate, in Surrey.

On site: what to expect

The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. Jobs in and around smaller places like Dawesgreen are usually planned as a single visit, so photos and measurements up front really help. Then the right materials arrive with us.

  1. First we go through the drawings, schedule or specification for the seals and ask about anything unclear.
  2. Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
  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. 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.

Preparing the site

  • Send asbestos survey details if the building is pre-2000
  • Make sure the joints can be reached
  • Arrange parking or a loading space

Request a quote

Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. The easiest way is to phone 01277 525 020 or email us.

How the quote is worked out

Before we quote, we look at:

  • Removal of failed or old sealant
  • Whether the work must be split into stages
  • How much there is to seal
  • Distance, for remote addresses

The product called for affects the cost, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.

Sending details for a quote

Whether it’s one area or a whole building, the same details help:

  • Drawings or a marked-up plan, if available
  • Any specification or named product
  • A wide shot and a close-up of the area
  • Asbestos survey details if the building is older

The quickest route to a quote is a few photos and the site postcode. Send them through the quote form, or call 01277 525 020 or email the details over if you’d rather talk the job through.

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

Block walls and concrete floors are common substrates for penetration seals. Dust and debris are cleared from the opening.

Looking after the joints

After handover, these steps help:

  • Keep product data and details in the fire safety file
  • Look above ceilings when tiles are lifted for other jobs
  • Get seals inspected before ceilings and boxing close
  • Brief every trade that openings they make must be sealed

New services after handover are a common way fire stopping gets breached. Building it into each contractor’s sign-off keeps the walls intact.

A simple record of seal locations and products helps. When a new service goes through, everyone knows which product and detail to match, which saves guesswork.
