Fire Rated Sealant in Southminster
Problem with your fire-stopping gaps in Southminster? We remove the old material, prepare the joints and seal them properly.
- Sealant items on a fire risk assessment action list
- Cracked or shrunken fire-rated sealant
- Open gaps behind door architraves
Keeping the joints in good condition
Looking after new joints is easy, and it makes a real difference:
- Look in service cupboards and ceiling voids from time to time
- Check whether a sealant can be painted before decorating over it
- File the fire-stopping record where your assessor can find it
- Flag any open gap you spot round a pipe or cable
File the record of locations and products with your fire safety paperwork. It helps whoever checks the building next.
Any job that breaks through a wall or ceiling should include resealing. Doing it at the time avoids leaving gaps behind.
Fire rated sealant in Southminster, done properly
Later work by other trades often breaks through fire stopping, especially in flats, HMOs, offices and schools. A new cable run or a replaced pipe can leave an open hole behind. We seal them with a product tested for that kind of gap. If you have gaps left after a refit or conversion and ordinary sealant used where a fire-rated product was needed, we can help, on service penetrations, door frames and linear gaps alike.
For a pub, café, guest house or shop in or near Southminster, the washrooms and kitchen need the same attention as a big site, and fire-rated sealant around service openings should be restored after new pipes or cables go through.
Our work is backed for twelve months.

DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
If you do try it yourself, take your time over the 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.

What the job involves on each surface
Masonry and concrete
Core-drilled and broken-out holes in concrete are often irregular. We measure the gap at its widest point against the product’s tested range.
Linear gaps
A linear joint may need to allow for movement as well as fire. The product and depth are chosen to suit both.
When to call us in Southminster
Many open fire-stopping gaps are made after the building is finished. New cables, pipes and data runs go through walls and ceilings and the hole they leave doesn’t always get resealed.
The most common problems we see are:
- Cracked or shrunken fire-rated sealant
- Linear gaps at the head of walls
- Unsealed gaps where pipes and cables go through a wall
- Ordinary sealant used where a fire-rated product was needed
Letting a property close to Southminster station? Then any gap left by new services in shared walls should be closed with a fire-rated product.

Landlords, agents and businesses in Southminster
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we will quote.
Commercial buildings in Southminster
Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, 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.
Community buildings like Church of St Leonard are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking. If you look after a building such as Southminster Church of England Primary School, fire-stopping around service openings should be restored whenever new services go in.

What we do, step by step
On the day, we start by going over the job with you. We protect the surfaces around the joints before any work starts. The work normally takes a few hours for a handful of gaps, and longer for a whole building. For a job in Southminster, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
- Each gap is measured and its substrate and service noted.
- Unsuitable material such as ordinary foam or silicone is cut out and the faces cleaned.
- We fit backing where needed and apply the fire-rated sealant to depth.
- We hand over a list of locations and products for your records.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Keep children and pets away from the work area
- Move anything stored near the joints

Advice
What happens if it’s left?
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. Homes in smaller places like Southminster can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we’ll go through it with you.
