Fire rated sealant for Boreham homes and businesses

Fire rated sealant for homes and businesses in Boreham

A fire seal relies on being installed the way it was tested: the right depth, the right backing and the right product for the substrate. That’s the part we focus on, gap by gap. If you’re dealing with gaps where walls meet ceilings or slabs and holes left by a change of layout, we can put it right, whatever the surface.

Commercial work around a smaller place like Boreham normally means a pub, a shop, a school or small business units rather than office blocks. Each needs the same care with its sealant as any larger building.

Our work is backed for twelve months, and the guarantee is the same wherever you are.

What happens if it’s left?

Sealant isn’t the fix for every opening. Big openings, bundles of cables and plastic pipes may need batts, collars or wraps instead. If a gap isn’t suitable for sealant, we will tell you. Around Boreham, water from a failed joint in an older home can soak into timber and plaster, and that’s a much bigger job than renewing the sealant.

Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

Why us?

  • We are fully insured
  • Sanitary silicone with an anti-fungal additive in wet areas
  • 20+ years of sealant experience
  • 180+ five-star Google reviews

Aftercare tips

Good habits help new joints last longer. Our tips:

  • Keep general-purpose foam and caulk away from fire-stopping gaps
  • Check whether a sealant can be painted before decorating over it
  • Make resealing part of every contractor’s brief
  • Include hidden areas like risers in routine checks

Avoid covering a sealed gap with anything that isn’t part of the tested detail. If it needs repair, use the same type of product. We can tell you which product we used.

Open gaps do not only matter in a fire: noise, draughts and even pests can come through too. Sealing them early helps on every front.

What affects the quote in Boreham

Some jobs are bigger than they look, and some smaller. The main factors:

  • How easy the joints are to reach
  • When we can work, for business premises
  • How many rooms, windows or areas are involved
  • How much old sealant there is and how hard it is to remove

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’ll give you a clear quote for the lot.

Asking for a quote

Surface by surface

Flats and HMOs

Flats and HMOs rely on fire separation between homes and the common parts. We seal the gaps your assessor has identified room by room.

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.

Common problems we fix in Boreham

A lot of fire stopping is out of sight: above ceilings, inside risers and behind panels. Because nobody sees it, gaps go unnoticed until an assessor or surveyor looks.

Most people get in touch when they notice something like this:

  • Unsealed gaps where pipes and cables go through a wall
  • Linear gaps at the head of walls
  • Sealant items on a fire risk assessment action list
  • Gaps filled with a product that isn’t fire-rated

For buildings such as Church of St Andrew, older buildings that have had new heating or wiring often have service gaps worth checking.

  • How hidden problems are handled
  • Whether you can choose the colour
  • What the cure time is

What fire rated sealant looks like in Boreham

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 work to the specification you are given, installing the product to its tested details.

If you look after a building such as Boreham Primary School, fire-stopping around service openings should be restored whenever new services go in. Rented homes near Beaulieu Park station change hands often, and fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

How the visit works

Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes from a few hours to a few days, depending on the number of gaps and the access and we leave things clean and tidy. Parking around Boreham is usually easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.

  1. Before starting, we go through the specification or action list with you.
  2. Each gap is measured and its substrate and service noted.
  3. Any non-fire-rated filler is removed and the faces cleaned.
  4. The specified fire-rated sealant goes in over any backing its detail requires.
  5. Every location is recorded with the product used for your records.

Getting ready for the visit

  • Plan for the work area to be out of bounds to pets and children
  • On commercial sites, let us know about site rules
  • Try not to wet indoor joints just before the visit

Advice

DIY sealant or a professional job?

What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.

Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

Your questions about fire rated sealant in Boreham

Is Boreham within the area you cover?

Yes, Boreham is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.

Can you help a landlord with a rental near Beaulieu Park station?

Yes, rental work is part of what we do. Just call 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear price.

Do I have to be there?

Access is agreed with you when the job is booked. Indoors, that usually means someone at home.

How long will you be here?

Most jobs take from a few hours to a few days, depending on the number of gaps and the access, including the preparation. We will confirm how long when we quote.

What do you put in the joint?

Products from Arbo and Everbuild, among others, chosen to suit the joint. We will tell you what we’re using and why.

Is it worth trying it myself?

Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.

Do you remove the old sealant?

Yes. We cut out all the old sealant and clean the joint before resealing.

Is there a guarantee?

Yes, for a year. If anything isn’t right with the work within the year, let us know and we’ll sort it.
