Fire rated sealant near Brighton and Hove

Can I do it myself?

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 does not 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 matched to the joint and its conditions.

What the job involves on each surface

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.

Flats and HMOs

Flats and HMOs rely on fire separation between homes and the common parts. We work through the gaps on your assessment, flat by flat if needed.

What fire rated sealant looks like in Brighton and Hove

If you run a hotel, guest house or holiday let in a coastal place like Brighton and Hove, heavy use in the busy months is hard on washroom and kitchen sealant, and any building work there should leave fire-rated joints made good. 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, and gaps around services are often picked up there. We work to the specification you are given, installing the product to its tested details.

For buildings such as Holy Cross Church, service openings in its walls need the right fire-rated sealant, as in any building. Rented homes near Aldrington station change hands often, and fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

Honest limits

In fairness, some problems need a different trade:

  • Problems with the door itself rather than the gap around the frame
  • Deciding what fire stopping a building needs
  • Sign-off of the building, which sits with building control or your assessor

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

Joints and surfaces we work on

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

Common problems we fix in Brighton and Hove

Gaps also open up as buildings move: a seal that cracks or pulls away leaves a path for smoke. Knocks, maintenance and building work damage it further.

Keep an eye out for any of the following:

  • Unsealed gaps around fire door frames
  • Gaps filled with a product that is not fire-rated
  • Cracked or shrunken fire-rated sealant
  • Fire stopping disturbed by later work

For site and facilities teams at buildings such as West Hove Infant School, fire-stopping around service openings should be restored whenever new services go in.

Questions to ask before you book

  • Whether the sealant suits the joint
  • How the surfaces are prepared before sealing
  • How long to leave it before use
  • What insurance they hold

Choosing a sealant specialist

How we quote for fire rated sealant

We don’t publish a price list. What we look at:

  • The number of rooms or windows
  • The type of sealant required
  • The size of the job
  • Any working-time requirements on site

Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you are unsure, phone 0345 464 0079 or email us for an honest opinion and a quote.

Asking for a quote

When you contact us, it’s useful to know:

  • Any previous sealing or DIY work
  • The rough size of the job
  • Any access issues, like height or stairs
  • Whether it’s a home or a business

Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is, and we’ll explain how we’d tackle it. Whenever you are ready, ring 0345 464 0079 or send us an email.

Work for landlords, hotels and businesses

Letting agents often deal with us directly. Tell us the address, the job and how access works.

Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.

How the visit works

When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a few hours for a handful of gaps, and longer for a whole building. For a job in Brighton and Hove, we need access to where the work is and somewhere nearby to park. If the job is outside, mention gates, side access and anything above ground floor.

  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. Backing or fill is fitted where the product’s tested detail calls for it.
  4. Fire-rated or intumescent sealant is applied to the right depth and tooled.
  5. We record the locations and products used for your records.

Before we arrive

  • Let us know about earlier repairs to the joints
  • Mention any sign-in or site rules at work premises
  • Let us know about parking restrictions

Advice

Questions from Brighton and Hove

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

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

Do you take on hotel work around Brighton and Hove?

Yes, hospitality work, including hotels, is part of what we do. Work can be planned room by room, and out-of-hours working can be arranged.

Do the sealants smell?

Some sealants have a smell while they cure. Opening a window helps.

Can you tell me how many minutes the seal will last?

Ratings and certification sit with the product’s test evidence and whoever specified the work. Our part is installing the specified product to its tested details and list the locations and products for you.

Is standard sealant good enough for a fire gap?

No. Standard sealants are not made or tested to stop fire. We cut it out and reseal with a fire-rated product.

How long does the job take?

It depends on the size of the job, but most jobs take anything from a few hours to several days, depending on how many gaps there are. We will tell you when we quote.

Can you seal over the old sealant?

No, it won’t last. It can look neat for a few weeks, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.

Do you offer different sealant colours?

Yes. Sealants come in white, clear, grey and other colours, and we’ll agree it with you first.
