Trusted fire rated sealant in Haggerston

Why deal with it now?

If an assessor has flagged gaps, it makes sense to close them before the next review. Having them sealed and recorded now gives you evidence that the item was dealt with. In London conversions, one flat’s bathroom is often above another flat’s ceiling, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Dealing with it early is far simpler.

Combining jobs into one visit normally makes better use of the time than several visits. We’ll give you a clear price for the lot.

Why us?

  • Experience in homes, commercial sites and hotels
  • Arbo and Everbuild products
  • 20+ years of sealant experience
  • 12-month guarantee on every job

Fire rated sealant for homes and businesses in Haggerston

Ordinary silicone or decorators’ caulk in a fire-stopping gap is not a fire-rated seal. Anything unsuitable comes out first and the gap is resealed with a product tested for that use. Typical jobs include open joints along the top of partitions and gaps flagged on a fire risk assessment, on pipe & cable gaps, plasterboard & masonry and door frames.

London blocks of flats carry pipes and cables through walls and floors in their common parts and service risers. For managing agents and building owners in Haggerston, that can mean fire-rated sealant around service openings as well as resealing in shared washrooms and kitchens.

Big or small, it’s backed by our one-year guarantee in Haggerston and across Greater London.

How we quote for fire rated sealant

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

  • When we can work, for business premises
  • Whether there’s mould to deal with
  • How easy the joints are to reach
  • How many rooms, windows or areas are involved

No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part.

Helping us quote

To make quoting easier, let us know:

  • Where the property is
  • Access, such as stairs, a lift or height
  • If it’s domestic, commercial or a hotel
  • If someone has resealed it before

For a quick quote, get us on the phone, or email us if that is easier. Describe what needs sealing and we’ll explain what’s involved and give you a clear price.

Aftercare tips

Aftercare is simple, and it makes a real difference:

  • File the fire-stopping record where your assessor can find it
  • Make resealing part of every contractor’s brief
  • Get damaged fire seals looked at promptly
  • Do not fill fire-stopping gaps with ordinary foam or silicone

Any fire seal that is cut or drilled needs resealing to its tested detail. New services through a sealed wall should include fire stopping in the plan.

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

The process

We keep the work tidy and contained to the area we’re working on, so you can carry on as normal. Expect the work to take from a few hours to a few days, depending on the number of gaps and the access, and we tell you how long to leave it before we go. In Haggerston, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.

  1. First we work through your list or survey, measuring each gap and checking what it’s formed in.
  2. Anything that is not fit for the job comes out, and the gap is cleaned.
  3. Backing or fill is fitted where the product’s tested detail calls for it.
  4. We apply the fire-rated or intumescent sealant to the specified depth and tool it.
  5. Finally, we list where we worked and what we used, for your records.

Before we arrive

  • Mention any sign-in or site rules at work premises
  • Tell us about any previous sealing or DIY attempts
  • Plan for the work area to be out of bounds to pets and children

Advice

DIY versus a professional finish

What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.

If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

Commercial buildings in Haggerston

There are hotels and other places to stay in and around Haggerston. For hotels, a room-by-room programme keeps most rooms in use while the work goes on. Many London buildings have tight access and loading restrictions, so out-of-hours working can be arranged where needed.

Schools such as Randal Cremer Primary School are buildings too, and gaps opened by contractors for new cabling are a common finding in schools and offices. For buildings such as Church of St Columba, older buildings that have had new heating or wiring often have service gaps worth checking. If you let a flat or house near Hoxton station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

Haggerston questions

Do you work for landlords with property near Hoxton station?

Yes, we work for landlords and letting agents. Just call 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear price.

Do you work for hotels and guest houses in Haggerston?

Yes. Hotel and guest-house work is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.

Is the work guaranteed?

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

Do you certify the fire stopping?

We do not give ratings or certificates for our work. The requirement comes from your assessor, designer or building control, and we fit a product whose tested details meet it.

Are you fully insured?

Yes, we’re fully insured for every job we do.

Is it OK to seal over old sealant?

No, because it fails. We remove every bit of old sealant first, so the new sealant bonds properly.

Do you seal gaps around fire door frames?

Yes, where the gap suits a sealant detail. Our work is the gap around the frame, and we’ll mention anything we notice about the door.

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.

How the job changes by surface

Linear gaps

Linear gaps run along the head of walls, at floor edges and between panels. They’re sealed with a fire-rated sealant over backing where the detail calls for it.

Plasterboard walls

Holes in plasterboard are often cut roughly for services. Gaps that are too big for sealant alone need a different detail and we’ll flag it.

When it isn’t the sealant

We will not take on work that will not last, so here’s what sealant cannot put right:

  • Problems with the door itself rather than the gap around the frame
  • Big openings where sealant alone is not the tested solution
  • Assessing a building’s fire safety

If you’re not sure, just ring 0345 464 0079 or email us and we’ll give you a straight answer.
