How we handle fire rated sealant in South Heath
Intumescent sealant looks much like any other sealant until it gets hot; then it swells to help close the gap. The right product depends on the gap size, the substrate and what passes through, so we work to the manufacturer’s details. Common call-outs are for fire stopping disturbed by later work and ordinary sealant used where a fire-rated product was needed, across linear gaps, door frames and pipe & cable gaps.
In a village or hamlet like South Heath, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. They all have washrooms, kitchens and service openings that need the right sealant.
There’s a 12-month guarantee on every job, whatever its size.

How the visit works
Good joint work is mostly preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it normally takes from a few hours to a few days, depending on the number of gaps and the access. Somewhere as small as South Heath, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Before starting, we go through the specification or action list with you.
- We measure every gap and note what it’s in and what passes through.
- Unsuitable material such as ordinary foam or silicone is cut out.
- We fit backing where needed and apply the fire-rated sealant to depth.
- Every location is recorded with the product used for your files.
Before we arrive
- For indoor joints, keep the area dry beforehand if you can
- Mention any parking rules near the property
- Keep pets and children clear of the area while we work

Advice
What we’re called out for in South Heath

- Gaps filled with a product that is not fire-rated
- Open gaps behind door architraves
- Fire stopping disturbed by later work
- Open joints along the top of partitions
Letting a property close to Great Bentley station? Then new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

Fire rated sealant in South Heath: local notes
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’re given, installing the product to its tested details.
Schools such as Colne Community School and College are buildings too, and service openings in fire-resisting walls need checking after any refurbishment.

When it isn’t the sealant
Sealant is not the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- Fire doors that need new seals, closers or hardware
- Walls or floors that weren’t built to resist fire
- Big openings where sealant alone is not the tested solution
If you are not sure, just phone 0345 464 0079 or send us an email and we will give you a straight answer.
What we seal
- Flats & HMOs
- Pipe & cable gaps

- Service penetrations
- Linear gaps
Why deal with it now?
Fire-rated sealants are less forgiving than ordinary ones. How it’s installed changes how it performs, so we follow the maker’s details on every gap. Where a wall is exposed, as many are in small places like South Heath, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Doing several joints on one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.

How the job changes by surface
Door frames
The gap between a door frame and the wall around it needs sealing as well as the door itself. We fill it with a fire-rated product suited to the materials either side.
Flats and HMOs
Converted houses often have gaps around old and new services. The gaps on your list are sealed with a fire-rated product and record where they are.
DIY sealant or a professional job?
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.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

I let a flat near Great Bentley station. Can you help?

Do you hold any approvals?

Can new sealant go over the old?
No, because it fails. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.

Do I need to be at home?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Can you tell me how many minutes the seal will last?
Ratings and certificates are not something we issue. The performance comes from the product’s tested details and the specification from your assessor or designer; we install to those details and record what we did.
How long does fire rated sealant take?
A typical job takes anything from a few hours to several days, depending on how many gaps there are. We will confirm how long when we quote.
