Fire stopping near Brands Hill

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

How the quote is worked out

Before we quote, we look at:

  • Specialist products, such as fire-rated or hygienic sealants
  • Travel to remote or island sites
  • Backing rod, priming and other preparation
  • Quantities, in metres or numbers

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 rules also count.

What we need to price the job

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

  • Approximate linear metres or a joint schedule
  • The type of building and who uses it
  • Asbestos survey details if the building is older
  • Access details, including height

Pricing a project or setting a maintenance budget? We will quote against your scope and drawings you can plan around. For a chat about it beforehand, call the office on 01277 525 020 or email us.

Fire stopping in Brands Hill, done properly

We should be clear about what we do and don’t do. Deciding the specification sits with the designer, the fire engineer and building control. What we bring is careful installation of the specified sealant, to the maker’s guidance on buildings around Brands Hill. If you are dealing with builders’ foam or ordinary silicone in compartment walls and hidden openings found during inspections, we can put it right, on linear gaps at wall heads, pipe penetrations and small duct penetrations where the tested detail allows alike. Looking for mastic applicators who cover Brands Hill? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.

Rural conversions around Brands Hill can put new fire-resisting partitions inside older structures. A penetration seal only performs as tested if product, substrate, service, gap and depth all match the detail.

A 12-month guarantee applies to all our work. Should something we installed fail, give us a call on 01277 525 020 or use the quote form and we will come back to it.

Brands Hill: questions and answers

Is a smaller place like Brands Hill outside your area?

No. Small places get the same service as large ones. London and every South East county are within our area. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.

What does the BS 476 change mean for fire-rated sealant in Brands Hill?

References to BS 476 classes are being removed from Approved Document B from 2 September 2029, after which BS EN 13501-2 classification is the route, subject to transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.

Do you guarantee your work?

Yes. It runs for twelve months and covers how we prepared and sealed the joints, but not damage, misuse or other trades’ work.

How do I request a quote?

There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photographs and a postcode.

What will the job cost?

We don’t publish prices, as every site differs. Send photos or drawings and we will price it at a fixed figure.

How long does a typical visit take?

It depends on the scope, though a typical visit usually takes anything from one day to a planned run of visits, depending on the number of seals and the access. Larger or phased jobs take longer, and we will give you a timescale with the quote.

Do you take on multi-site work?

Yes. A group of buildings can go on one quote, with one point of contact.

Compartments and services around Brands Hill

Central London is about 19 miles from Brands Hill. Office refits around the commuter belt bring new cabling through fire-resisting walls, and the gaps need sealing with the specified product. Fire stopping of openings and penetrations in England falls under 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. We install whatever has been specified, to the product’s tested detail.

For a hotel such as Arora Park Hotel, which lies east of Brands Hill, penetration seals are worth checking after any refit or services upgrade. At a healthcare site like Upton Hospital (2.9 miles north-west of Brands Hill), new services through compartment walls are a constant, and each needs the specified seal.

Brands Hill is about 3 miles south-west of West Drayton, in Windsor and Maidenhead. Our applicators travel to Brands Hill for work on service penetrations. Our Windsor and Maidenhead coverage takes in 60 places, large and small. London is covered too, some 19 miles away.

Do you need fire stopping in Brands Hill?

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.

Common reasons buildings call us in:

  • Fire sealant pulled out of the opening
  • Fire stopping installed outside its tested range
  • Builders’ foam or ordinary silicone in compartment walls
  • Head-of-wall gaps with no fire seal

Offices at parks like Heathrow West Business Park (to the north of Brands Hill) are re-cabled with each new tenant, and compartment walls need sealing afterwards to the tested detail.

Comparing quotes

  • Is the sealant right for the movement and the substrate?
  • How joint depth will be controlled
  • Will RAMS and insurance details be available?
  • Their plan for phasing and protecting the area

Questions to ask before you appoint anyone

Building owners, agents and FMs in Brands Hill

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.

Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.

Leave it or put it right?

Open service penetrations matter on ordinary days, not just in a fire: they also carry noise, draughts and smells between rooms. Sealing them to the specified detail deals with the fire risk first, and the other benefits follow. One visit to deal with every failing joint makes more sense than several trips to a place like Brands Hill, rather than one at a time. Send photos of each area and we will quote for the lot.

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.

Why appoint us

  • One contact handling all your sites
  • Failed material removed, not covered up
  • Work to your specification and the manufacturer’s guidance
  • Fully insured

Take a look at our cost guide or how we’re accredited.

On site: what to expect

In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before the next one starts. If others near Brands Hill need work, visits can be combined. A fixed quote is given before anything starts.

  1. The specification and schedule come first, so we know which details apply.
  2. Access, permits and the order of areas are agreed with the site team.
  3. Each opening is checked for wall or floor type, service, gap and depth.
  4. Foam, ordinary sealant and debris come out first.
  5. The specified backing and sealant go in to depth and are finished neatly.
  6. Anything outside the detail is reported to you rather than sealed.

Before we start on site

  • Tell us your opening times and when work is allowed
  • Tell us which areas need to stay in use
  • Arrange parking or a loading space

When it isn’t the sealant

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

  • Approving the work on behalf of building control
  • Designing or specifying fire stopping, which sits with the designer or fire engineer
  • Fire risk assessments, a job for a competent assessor

If in doubt, phone 01277 525 020 or use the quote form and we’ll say what we think before you book.

What we seal

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