When something else is needed

We’d rather tell you now than do work that will not last, so these are the limits:

  • Assessing a building’s fire safety
  • A wall that is not a fire-resisting element to begin with
  • Large holes that need a different fire-stopping system

If in doubt, ring 0345 464 0079 or send us an email and we’ll say what we think.

Where we work in Broad Oak

  • Plasterboard & masonry
  • Flats & HMOs

Fire rated sealant for homes and businesses in Broad Oak

A gap around a door frame, a linear joint at the head of a wall and a hole round a pipe are each sealed differently. Measuring the gap and checking what it’s made of comes first, then apply it to the depth its tested detail calls for. Typical jobs include unsealed gaps where pipes and cables go through a wall and gaps left after a refit or conversion, on flats & HMOs, linear gaps and door frames.

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

All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

When to call us in Broad Oak

Movement in the structure can open gaps too: cracked or debonded sealant leaves an open route through the wall. Knocks, maintenance and building work damage it further.

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

  • Sealant items on a fire risk assessment action list
  • Holes left by a change of layout
  • Gaps around pipes and cables through fire-resisting walls
  • Seals cut through by electricians, plumbers or data installers

FAQs for Broad Oak

Can you do fire rated sealant in Broad Oak?

Yes. Our work covers London and the South East, and Broad Oak is part of that. You can ring 0345 464 0079 or send us an email and let us know what needs doing, and we will send you a clear quote.

Can you help a landlord with a rental near Stonegate station?

Yes, we work for landlords and letting agents. You can ring 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before any work starts.

Do you provide details of the products used?

Yes. When the job is done, we give you the locations and products. Tell us if your assessor needs it in a particular format.

Will you assess my building’s fire safety?

No. That’s for a fire risk assessor, designer or building control. We apply fire-rated sealant to the requirements they set.

Do you take out the old sealant first?

Yes. All of the old material is cut out and the joint cleaned before applying anything new.

Can you fill the gap behind a fire door frame?

Yes, if the gap is within the product’s tested range. Our work is the gap around the frame and we will tell you if we spot problems with the door.

Is it messy?

Very little: the area around the joints is protected first, and we tidy up before we go.

Can new sealant go over the old?

No. Fresh sealant doesn’t stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.

DIY versus a professional finish

If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.

The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.

For landlords and businesses

Landlords and letting agents in Broad Oak can book us as well as householders. Sealant work between tenants is a simple way to keep a property in good order.

Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we’ll give you a quote.

Leave it or put it right?

A quick fill with any sealant to hand isn’t fire stopping. Fire-rated products are tested in set gap sizes, depths and substrates, so both the product and the method matter. In a small place like Broad Oak, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

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 any work starts.

Why us?

  • We leave the area clean and tidy
  • 20+ years of sealant experience
  • We’re fully insured
  • Rated 4.9 stars on Google

What fire rated sealant looks like in Broad Oak

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’re given, installing the product to its tested details.

Schools such as Broad Oak Community Primary School are buildings too, and service openings in fire-resisting walls need checking after any refurbishment. For buildings such as Ebenezer Chapel, service openings in its walls need the right fire-rated sealant, as in any building.

What we do, step by step

All our tools and materials come with us in the van, so you do not need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. Most jobs take anything from a few hours to several days, depending on how many gaps there are. In a small place like Broad Oak, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. First we work through your list or survey, measuring each gap and checking what it’s formed in.
  2. Old or unsuitable sealant is cut out and the gap 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. Locations and products are noted so you have them on file.

Getting ready for the visit

  • Try not to wet indoor joints just before the visit
  • Clear items away from the joints we’re working on
  • Let us know about earlier repairs to the joints

Advice

Surface by surface

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.

Flats and HMOs

In occupied buildings, we plan the order of work with you. Access to flats and common areas is agreed in advance so residents know what to expect.
