Fire rated sealant in Outwood, done properly

We don’t assess buildings or decide what fire stopping is needed; that comes from your fire risk assessor, designer or building control. Our part is applying the specified sealant carefully, to the right depth and with the right backing. If you are dealing with joints picked up in a fire-stopping survey and unsealed gaps where pipes and cables go through a wall, we can help.

If you have holiday lets, a converted barn used for business or a community building near Outwood, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.

Big or small, you get the same 12-month guarantee in Outwood and across Surrey.

Workplaces and buildings in Outwood

Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, and gaps around services are often picked up there. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.

Community buildings like Church of St John the Baptist are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking. For site and facilities teams at buildings such as Oakwood School, fire-stopping around service openings should be restored whenever new services go in.

Outwood is about 3 miles east of Horley, in Surrey. Homes, rented property, offices and hotels in Outwood can book us for fire rated sealant, old or new, large or small. The work is guaranteed for a year. Our area takes in 395 places across Surrey, from the larger towns to small villages. Our Crawley page covers work nearby (7 miles or so).

What we’re called out for in Outwood

Buildings are refitted and reconfigured over the years. Conversions to flats and HMOs, and office refits, create new walls and new routes for services, with gaps to match.

It’s worth asking for a quote if you see:

  • Old fire sealant that has split or come away
  • Seals cut through by electricians, plumbers or data installers
  • Gaps around pipes and cables through fire-resisting walls
  • Unsealed gaps around fire door frames

Letting a property close to Salfords station? Then new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

What your quote should include

  • Is VAT in the price?
  • Is the old sealant removed completely?
  • Whether you can choose the colour
  • Who does the work, and how experienced they are

Our hiring checklist

Aftercare tips

Good habits help new joints last longer. Our tips:

  • Check whether a sealant can be painted before decorating over it
  • File the fire-stopping record where your assessor can find it
  • Make resealing part of every contractor’s brief
  • Check risers, ceiling voids and cupboards during building checks

Let contractors know where fire stopping has been done, and ask them to reseal anything they cut through. Later work is a common cause of damaged fire stopping.

A flagged gap shouldn’t wait for the next assessment. Get it sealed and recorded.

Honest limits

We will always be straight with you, so here’s what sealant cannot fix:

  • Walls or floors that weren’t built to resist fire
  • Doors that aren’t fire doors in the first place
  • Large holes that need a different fire-stopping system

If you’re not sure, just call 0345 464 0079 or drop us an email and we’ll give you a straight answer before booking.

How the visit works

On the day, there’s very little for you to do. Show us the job and we will take it from there. The job generally takes a few hours for a handful of gaps, and longer for a whole building. Somewhere as small as Outwood, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We plan the order of work and access, floor by floor or flat by flat.
  2. We take out any damaged or unsuitable sealant.
  3. Gaps are cleaned of dust and loose material.
  4. We apply and tool the sealant to the product’s tested detail.
  5. Locations and products are written up and any gaps unsuitable for sealant are flagged.

Getting ready for the visit

  • Where the joints are inside, avoid wetting them before we arrive
  • Mention if the joints have been sealed before
  • Keep children and pets away from the work area

Ask for a quote

The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and email photos if that is easy.

Different surfaces, different methods

Flats and HMOs

Converted houses often have gaps around old and new services. The gaps on your list are sealed with a fire-rated product.

Door frames

We deal with the gap around the frame, not the door. The door leaf, its seals and closer need a door specialist and we will mention anything we notice.

What affects the cost of fire rated sealant

You’ll get a clear quote before we start. It takes into account:

  • Working hours on commercial sites
  • Whether old sealant or filler has to be cut out
  • The amount of work
  • Whether there’s mould to deal with

Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.

Asking for a quote

What to tell us when you ask for a quote:

  • Any access issues, like height or stairs
  • Whether it has been sealed before
  • How many joints, rooms or windows are involved
  • What’s wrong with the joints now

Common questions in Outwood

Is Outwood within the area you cover?

Yes. Outwood is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.

Do you work for landlords with property near Salfords station?

Yes, we work for letting agents and landlords. Just call 0345 464 0079 or email us and tell us about the property, and we will send you a clear quote.

Can I choose the sealant colour?

Generally, yes. White, clear and grey are common, and other colours are available for many products, and we agree the colour with you before work begins.

Do you seal gaps around fire door frames?

Yes. We often seal open gaps hidden behind the architrave. Doors, seals and closers need a door specialist.

What sealant do you use?

It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.

Is it worth trying it myself?

Sometimes. 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.

Can you do several jobs on one visit?

Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.

What information do you need?

Only a few details: the address or postcode, what’s wrong and any access issues. Then call 0345 464 0079 or send us an email.

For landlords and businesses

We work for landlords and letting agents as well as homeowners. Sealant work between tenants keeps a property looking cared for before the next move-in.

Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
