Fire rated sealant in Hinxton

Honest limits

Sealant is not the answer to every problem, and we’d rather say so up front. Sealant won’t put right:

  • Fire risk assessments, which need a qualified assessor
  • Fire doors that need new seals, closers or hardware
  • Large holes that need a different fire-stopping system

Not sure which it is? You can phone 0345 464 0079 or drop us an email and we’ll tell you honestly before you book.

What we seal

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

Fire rated sealant in Hinxton

We can work through a building room by room or floor by floor. It gives you a list to keep with the building’s fire safety documents. We work on linear gaps, service penetrations and flats & HMOs, and people most often call us about open holes round services passing through fire walls and fire stopping disturbed by later work.

Somewhere as small as Hinxton, commercial jobs tend to be pubs, holiday lets, farm buildings or halls rather than offices. Each still needs sound sealant in its washrooms and kitchens, and fire-rated joints where services pass through walls.

All our work comes with a one-year guarantee, wherever you are in Essex.

What affects the cost of fire rated sealant

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

  • Working hours on commercial sites
  • Which sealant suits the joint
  • Mould in or behind the old joints
  • The amount of work

Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs. Ask us for a quote and we will go through it with you.

What to tell us for a quote

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

  • Photos by email, if that’s easy
  • How many joints, rooms or windows are involved
  • Where the property is
  • The problem you’ve noticed

The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is.

Looking after it afterwards

To keep the joints looking good and working properly:

  • Get damaged fire seals looked at promptly
  • Plan fire stopping into any work that goes through walls or floors
  • Never patch a fire seal with standard sealant
  • Ask which product was used before you paint

File the record of locations and products with your fire safety paperwork. It saves time at the next inspection or assessment.

If a fire risk assessment has flagged a gap, do not leave it for the next one. Get it sealed and recorded so you can show it was dealt with.

When to call us in Hinxton

Gaps around door frames are easily missed. The gap between the frame and the wall is hidden behind the architrave, so it can be left open when a door is replaced.

Keep an eye out for any of the following:

  • Open gaps behind door architraves
  • Open holes round services passing through fire walls
  • Old fire sealant that has split or come away
  • Gaps flagged on a fire risk assessment

If you let a flat or house near Whittlesford Parkway station, any gap left by new services in shared walls should be closed with a fire-rated product.

Questions to ask before booking

  • Which sealant they’ll use, and why
  • How long the guarantee is
  • What happens if the job turns out different
  • Whether VAT is included

How to choose a mastic man

DIY versus a professional finish

Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.

Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

Fire rated sealant around Hinxton

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.

If you look after a church, hall or community building such as Parish Church of St Mary and St John the Evangelist, older buildings that have had new heating or wiring often have service gaps worth checking.

Hinxton questions

Do you cover Hinxton for fire rated sealant?

Yes. Our work covers London and the South East, and Hinxton is part of that. Just ring 0345 464 0079 or drop us an email with a few details of the job, and we’ll send you a clear quote.

Can you help a landlord with a rental near Whittlesford Parkway station?

Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just ring 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear quote.

What’s the difference between intumescent and fire-rated sealant?

Intumescent means it swells when heated, helping close the gap. Intumescent sealants are one kind of fire-rated sealant; the right one depends on the gap and what passes through it.

What fire rating will the seal have?

That is not something we state or certify. The requirement comes from your assessor, designer or building control, and we fit a product whose tested details meet it, recording the locations and products.

Should I try DIY first?

It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.

Are you an approved applicator?

Yes. Mr Mastic is an ARBOMaster approved applicator and we’re fully insured too.

Do the sealants smell?

Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.

Can you do several jobs on one visit?

Yes, we can. More than one area can be quoted together.

What we do, step by step

We work through the job in order: protect, prepare, seal, tidy. Typically it takes a few hours for a handful of gaps, and longer for a whole building, and the area is left clean. Somewhere as small as Hinxton, 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. Dust and loose debris are cleaned from each gap.
  4. The fire-rated or intumescent sealant is applied and tooled to the tested detail.
  5. Locations and products are written up and any gaps unsuitable for sealant are flagged.

Preparing for the visit

  • Mention if the joints have been sealed before
  • Tell us about access, such as stairs, a lift or high-level joints
  • Tell us if parking is tricky

Surface by surface

Service penetrations

A copper pipe, a cable and a plastic pipe can all need different fire-stopping details. Each one is sealed to the product’s tested detail and we flag any that need another system.

Door frames

A door can only do its job if the gap behind its frame is sealed too. We seal that gap with a fire-rated sealant suited to the frame and wall.
