Fire rated sealant in Heathfield

How we quote for fire rated sealant

The price is agreed before any work begins. It takes into account:

  • The old material and how stubborn it is
  • How many areas need sealing
  • Whether the work is at height
  • Any mould that needs treating

Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.

What we need to know

Photos by email are helpful but not essential. Please mention:

  • Where the job is, and your postcode
  • What the problem is, such as mould, gaps, leaks or cracking
  • Whether it’s a home or a business
  • The rough size of the job

To get a quote, phone 0345 464 0079 or send us an email and tell us where the job is and what the problem looks like. You’ll have a clear quote before work begins.

About our fire rated sealant in Heathfield

A fire seal relies on being installed the way it was tested: correct depth, correct backing and a product suited to the surfaces. That detail is what we take care over, gap by gap. We work on linear gaps, plasterboard & masonry and pipe & cable gaps, and common reasons people get in touch are ordinary sealant used where a fire-rated product was needed and gaps where walls meet ceilings or slabs.

For a pub, café, guest house or shop in or near Heathfield, the washrooms and kitchen need the same attention as a big site, and fire-rated sealant around service openings should be restored after new pipes or cables go through.

Our work is backed for twelve months.

DIY versus a professional finish

Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.

Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

How the visit works

Most of a good job is in the preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it normally takes anything from a few hours to several days, depending on how many gaps there are. A visit to Heathfield is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.

  1. First we work through your list or survey, measuring each gap and checking what it’s formed in.
  2. Anything that is not fit for the job comes out, and the gap is cleaned.
  3. Where the tested detail needs backing or fill, we fit it.
  4. The sealant goes in to the depth its detail sets, then it’s tooled off.
  5. Finally, we list where we worked and what we used, for your records.

Preparing for the visit

  • Let us know about parking restrictions
  • Tell us about any previous sealing or DIY attempts
  • Where the joints are inside, avoid wetting them before we arrive

Commercial buildings in Heathfield

If you run a hotel, guest house or holiday let in a coastal place like Heathfield, busy months put washrooms and kitchens under pressure, so it’s worth checking the sealant before the busiest weeks. In England, the Regulatory Reform (Fire Safety) Order 2005 requires a fire risk assessment for workplaces and for the common parts of blocks of flats, which is often where open fire-stopping gaps are first noticed. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.

Community buildings like St Columba are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking. If you let a flat or house near Fareham station, any gap left by new services in shared walls should be closed with a fire-rated product.

What we’re called out for in Heathfield

Door frames are a common weak spot. The architrave hides the gap between frame and wall, so it’s easy to leave unsealed when doors are changed.

Common reasons people contact us include:

  • Fire stopping disturbed by later work
  • Standard silicone or caulk in a fire-stopping gap
  • Open holes round services passing through fire walls
  • Gaps flagged on a fire risk assessment

For site and facilities teams at buildings such as Ranvilles Infant School, fire-stopping around service openings should be restored whenever new services go in.

What to look for in a quote

  • How the surfaces are prepared before sealing
  • Is the old sealant removed completely?
  • Are they insured?
  • How the colour is chosen

Our hiring checklist

Different surfaces, different methods

Linear gaps

Head-of-wall gaps are often hidden above suspended ceilings. We work along the whole run.

Masonry and concrete

Preparation counts on brick, block and concrete. The gap is cleaned and backed where required.

What sealant work can’t fix

In fairness, there are a few things sealant won’t fix:

  • Assessing a building’s fire safety
  • Sign-off of the building, which sits with building control or your assessor
  • Openings too large for sealant, which need batts, boards or another system

If you’re not sure, just phone 0345 464 0079 or email us and we will give you a straight answer.

Surfaces we seal

  • Plasterboard & masonry
  • Flats & HMOs
  • Door frames
  • Linear gaps
  • Pipe & cable gaps
  • Service penetrations

Looking after it afterwards

Simple care keeps the joints in good condition. We recommend:

  • Look in service cupboards and ceiling voids from time to time
  • File the fire-stopping record where your assessor can find it
  • Include fire stopping when you schedule refits
  • Check whether a sealant can be painted before decorating over it

Don’t add foam, filler or ordinary sealant over a fire seal. Repairs should use a matching fire-rated product. Ask us if you are not sure which product was used.

An open gap isn’t only a fire issue: noise, draughts and even pests can come through too. Sealing them early helps on every front.

Do you take on hotel work around Heathfield?

Yes, we work for hotels as well as homes and businesses. A room-by-room programme keeps most rooms in use while the work goes on.

Can I do it myself?

You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.

Do you come to Heathfield?

Yes. From our base in Crawley, we cover South East England, London and all of Scotland.

Do you remove the old sealant?

Yes. We cut out all the old sealant and clean the joint before applying anything new.

What information do you need?

The location, the problem and the rough size of the job. If you can, email a few pictures.

Can I use normal mastic around a pipe through a fire wall?

No. It looks sealed but will not perform as fire stopping. Use a product tested for that gap and service, or ask us to do it.
