What else we do in East Dean
Leave it or put it right?
Items left open on a fire risk assessment tend to come back at the next review. Having them sealed and recorded now gives you evidence that the item was dealt with. Where a wall is exposed, as many are in small places like East Dean, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.

East Dean: your questions answered
Is East Dean in your area for fire rated sealant?
Yes. We work across London and the South East, and East Dean is part of that. You can phone 0345 464 0079 or send us an email and tell us what needs doing.
Can you help a landlord with a rental near Eastbourne station?
Yes, we work for landlords and agents. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before we start.
Is it OK to seal over old sealant?
No, because it fails. The old sealant always comes out first, so the new joint bonds to clean surfaces.
What does intumescent mean?
Fire-rated is the broad term for sealants tested for fire stopping. Intumescent types expand when heated, and they’re one option among several. The specification and the tested detail decide which is used.
Do you seal gaps around fire door frames?
Yes, where the gap suits a sealant detail. We seal the frame-to-wall gap, not the door itself.
Do I need to be at home?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that usually means someone at home.
Do the sealants smell?
There can be a smell while the sealant cures, but it fades. Ventilation helps.
Will you leave a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
What affects the quote in East Dean
For a quick quote, just ask. What matters most is:
- The size of the job
- Any mould that needs treating
- Whether the work is at height
- The type of sealant required
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.
Helping us quote
Photos by email are helpful but not essential. Try to tell us:
- How many joints, rooms or windows are involved
- Pictures of the joints, sent by email
- The address or postcode of the job
- The type of property
Getting a quote is simple: let us know what needs doing and where, and roughly how big it is. Photos by email help us understand the job, and we will take it from there.
What fire rated sealant looks like in East Dean
If you run a hotel, guest house or holiday let in a coastal place like East Dean, 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, 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 let a flat or house near Eastbourne station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

What we are called out for in East Dean
Movement in the structure can open gaps too: a seal that cracks or pulls away leaves a path for smoke. Knocks, maintenance and building work damage it further.
It’s worth asking for a quote if you see:
- Fire stopping disturbed by later work
- Standard silicone or caulk in a fire-stopping gap
- Gaps left after a refit or conversion
- Open gaps behind door architraves
Community buildings like The Parish Church of St Simon and St Jude are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking.
Questions to ask before booking
- How the joint is cleaned and prepared
- Is the old sealant removed completely?
- The length of the guarantee
- Whether VAT is included
Can I do it myself?
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
The process
Most of a good job is in the preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes anything from a few hours to several days, depending on how many gaps there are. In a small place like East Dean, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
- We measure every gap and note what it’s in and what passes through.
- Any non-fire-rated filler is removed and the gap cleaned.
- The specified fire-rated sealant goes in over any backing its detail requires.
- We hand over a list of locations and products for your files.
Preparing for the visit
- Mention any sign-in or site rules at work premises
- Plan for the work area to be out of bounds to pets and children
- Mention if the joints have been sealed before

- Walls or floors that weren’t built to resist fire
