Fire rated sealant in Braintree

About our fire rated sealant in Braintree

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 flats & HMOs, service penetrations and door frames, and common reasons people get in touch are new service routes left unsealed after building work and gaps where walls meet ceilings or slabs.

For landlords in a large town like Braintree, sealant work comes in two kinds: resealing bathrooms and kitchens, and fire-rated sealant where pipes pass through walls. We can quote for a single property or a whole portfolio.

Big or small, you get the same one-year guarantee in Braintree and across Essex.

Do you need fire rated sealant in Braintree?

Lots of unsealed gaps appear long after the building was completed. New cables, pipes and data runs go through walls and ceilings and the hole round the new service is not always sealed again.

Most people get in touch after spotting something like this:

  • Open joints along the top of partitions
  • Gaps flagged on a fire risk assessment
  • Cracked or shrunken fire-rated sealant
  • Door frames with gaps between frame and wall

For landlords with property near Braintree station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

10 questions to ask before booking

What affects the cost of fire rated sealant

We quote each job individually. This is what makes a difference:

  • The product the joint needs
  • Any mould that needs treating
  • How easy the joints are to reach
  • Whether old sealant or filler has to be cut out

Doing several joints on one visit generally makes better use of the time than several visits, so tell us about everything that needs sealing. We will give you a clear quote for the lot.

What we need to know

A few details help us give you an accurate quote. When you get in contact, it helps to mention:

  • Pictures of the joints, sent by email
  • Any access issues, like height or stairs
  • Any previous sealing or DIY work
  • The type of property

Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is, and we will talk you through what we’d do. When it suits you, ring 0345 464 0079 or send us an email.

Common questions in Braintree

Do you work in hotels near Braintree?

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.

Do you cover Braintree for fire rated sealant?

Yes, Braintree is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or send us an email with a few details of the job.

Do you seal gaps around fire door frames?

Yes. We seal the gap between the frame and the wall with a suitable fire-rated product, to the product’s details. The door, its seals and closer are for a door specialist.

Do you guarantee your work?

Yes, for a year. If there’s a problem with our work in that time, tell us and we’ll put it right.

Where are you based?

Mr Mastic is based in Crawley. Our applicators cover Braintree, along with the rest of our area.

Is standard sealant good enough for a fire gap?

No. A gap that needs fire stopping needs a tested fire-rated product, installed to its details.

Do you hold any approvals?

Yes. We hold ARBOMaster approved applicator status, and we are fully insured.

Is intumescent sealant the same as fire-rated sealant?

An intumescent sealant expands when it gets hot to help seal the gap. It’s one type of fire-rated sealant; the right one depends on the gap and what passes through it.

Looking after it afterwards

After the cure time, these simple habits help:

  • Don’t paint over fire sealant until it has cured
  • Keep pictures of seals that will be hidden
  • Never patch a fire seal with standard sealant
  • Report cracked or damaged seals as soon as you notice them

File the record of locations and products with your fire safety paperwork. It helps whoever checks the building next.

It’s easiest to seal gaps while they’re few and easy to reach. Over time, more work adds more holes.

Why act early in Braintree

Paying for fire stopping that has to be redone is a false economy. If the details weren’t followed, the seal may need redoing when the building is next checked. In flats, shops and offices in Braintree, a failed joint can let water into the unit below or behind a wall, where it’s often found late and is bigger to put right.

The cost depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before work begins.

Different surfaces, different methods

Linear gaps

Long, narrow gaps appear where walls meet slabs and ceilings. They’re sealed with a fire-rated sealant over backing where the detail calls for it.

Service penetrations

New gaps tend to show up where services have been added. Old or unsuitable filler comes out before the right sealant goes in.

What fire rated sealant looks like in Braintree

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 work to the specification you are given, installing the product to its tested details. Braintree has hotels and guest accommodation in and around it. Hotel work can be planned room by room, with out-of-hours working where needed.

Schools such as Great Bradfords Infant and Nursery School are buildings too, and fire-stopping around service openings should be restored whenever new services go in. Community buildings like Congregational Church are part of the picture too: gaps around pipes and cables are worth checking after any building work there.

When something else is needed

To be straight with you, there are a few things sealant will not fix:

  • Fire risk assessments, which need a qualified assessor
  • Big openings where sealant alone isn’t the tested solution
  • Walls or floors that weren’t built to resist fire

Not sure which it is? You can ring 0345 464 0079 or email us and we will tell you honestly before booking.

What happens on the day

Most of a good job is in the preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for a handful of gaps, and longer for a whole building. Where a business in Braintree needs to stay open, out-of-hours working can be arranged, and homes are booked within our usual hours, Monday to Saturday.

  1. We plan the order of work and access, floor by floor or flat by flat.
  2. Old, damaged or unsuitable sealant is removed.
  3. Gaps are cleaned of dust and loose material.
  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.

How to prepare
