Fire rated sealant across Southend-on-Sea: what to expect

Filling a fire-stopping gap with standard silicone or caulk doesn’t make it fire-rated. Anything unsuitable comes out first and reseal with a fire-rated product tested for that kind of gap. Common call-outs are for fire stopping disturbed by later work and gaps where walls meet ceilings or slabs, across linear gaps, plasterboard & masonry and door frames.

There’s no need to move everything out, only the area right around the joints. Everything nearby is protected, and the job takes a few hours for a handful of gaps, and longer for a whole building for a typical job.

We plan the order of work and access, floor by floor or flat by flat.
Old, damaged or unsuitable sealant is removed.
Gaps are cleaned of dust and loose material.
We apply and tool the sealant to the product’s tested detail.
We record what was done and flag anything that needs a different system.

Fire rated sealant across Southend-on-Sea: local notes

Across Southend-on-Sea, from Prittlewell, Shoeburyness and Leigh-on-Sea outwards, offices, hotels, schools and shops all need sealant work from time to time.

Hard water across most of the South East leaves limescale on sealant, grout and fittings. Whatever the job in Southend-on-Sea, surfaces are cleaned back properly before new sealant goes in. Coastal guest houses and holiday lets in Southend-on-Sea can see heavy use in busy months, which is hard on sealant and grout.

Southend-on-Sea: If you look after a church, hall or community building such as Church of St Mary, older buildings that have had new heating or wiring often have service gaps worth checking. For site and facilities teams at buildings such as Westborough Academy, service openings in fire-resisting walls need checking after any refurbishment.

When it is not the sealant

To be straight with you, some problems need a different trade:

Problems with the door itself rather than the gap around the frame
Construction that doesn’t provide fire resistance on its own
Issuing a fire rating or certificate for a building

DIY sealant or a professional job?

The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.

Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

Common problems we fix in Southend-on-Sea

Lots of unsealed gaps appear long after the building was completed. New cables, pipes and data runs go through walls and ceilings and the hole they leave does not always get resealed.

People generally contact us when they notice something like this:

Standard silicone or caulk in a fire-stopping gap
Unsealed gaps where pipes and cables go through a wall
Open joints along the top of partitions
New service routes left unsealed after building work

Different surfaces, different methods

Linear gaps

Long, narrow gaps appear where walls meet slabs and ceilings. They’re sealed with a fire-rated sealant over backing where the detail calls for it.

Plasterboard walls

Plasterboard partitions are common in flats, offices and conversions. We use a product tested in that kind of wall for the gap we are sealing.

Work for landlords, hotels and businesses

Letting agents often deal with us directly. Tell us the address, the job and how access works and we’ll give you a quote.

Mouldy or split sealant often shows up at the end of a tenancy. We can quote for more than one property at once.

Southend-on-Sea: your questions answered

Will you leave a mess?

We keep the work tidy. We protect what’s around the joints, and we clear up when we are done.

Do the sealants smell?

There can be a smell while the sealant cures. Opening a window helps.

Do you offer different sealant colours?

Most of the time, yes. We will explain which colours are available and agree one before we start.

Do you work in flats, HMOs and commercial buildings?

Yes. Flats, HMOs, offices, schools and other occupied buildings are all part of our work. We agree access and the order of work with you first.

How long will you be here?

That depends on the amount of work, but most jobs take a few hours for a handful of gaps, and longer for a whole building. We will tell you when we quote.

How much does fire rated sealant cost in Southend-on-Sea?

It depends on the job, so we quote each one individually. To get one, phone 0345 464 0079 or send us an email and let us know what needs doing and where.

Do you seal gaps around fire door frames?

Yes. The joint between frame and wall is sealed with a fire-rated sealant. The door leaf and its hardware need a door specialist.
