Fire rated sealant in Horndean
We don’t assess buildings or decide what fire stopping is needed; that comes from your fire risk assessor, designer or building control. What we do is apply the right product to that specification, properly and neatly. We work on pipe & cable gaps, service penetrations and plasterboard & masonry, and the jobs we see most are open holes round services passing through fire walls and door frames with gaps between frame and wall.
Washrooms in busy buildings wear their sealant out faster than a bathroom at home, and fire-rated joints need restoring whenever new services are run through a wall. In Horndean, timings are planned around the building.
Big or small, it’s backed by our 12-month guarantee in Horndean and across Hampshire.

How the job changes by surface
Masonry and concrete
Core-drilled and broken-out holes in concrete are often irregular. We measure the gap at its widest point to make sure it suits the product.
Door frames
Frame gaps are usually hidden behind the architrave. Where it’s open, we seal it to the product’s details for that gap size before the trim goes back.
Quotes for fire rated sealant in Horndean
Some jobs are bigger than they look, and some smaller. The main factors:
- How many rooms, windows or areas are involved
- Which sealant suits the joint
- How easy the joints are to reach
- Any working-time requirements on site
Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you are not sure whether it needs doing, ring 0345 464 0079 or email us and we’ll give you an honest view and a quote.
Asking for a quote

- Roughly how big the job is
- If someone has resealed it before
- Where the property is

Workplaces and buildings in Horndean
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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
If you look after a church, hall or community building such as Saint Wilfrid's, older buildings that have had new heating or wiring often have service gaps worth checking. If you let a flat or house near Rowlands Castle station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

Signs you need fire rated sealant in Horndean
Door frames are a common weak spot. The gap between the frame and the wall is hidden behind the architrave, so it can be left open when a door is replaced.
Keep an eye out for any of the following:
- Cracked or shrunken fire-rated sealant
- Door frames with gaps between frame and wall
- Gaps filled with a product that isn’t fire-rated
- Linear gaps at the head of walls
Managing a site like Horndean Technology College? Then gaps opened by contractors for new cabling are a common finding in schools and offices.

Horndean: your questions answered
Do you cover Horndean for fire rated sealant?
Yes, Horndean is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or email us with a few details of the job.
I let a flat near Rowlands Castle station. Can you help?
Yes, rental work is part of what we do. You can call 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before work begins.
Do you have insurance?
Yes. We’re fully insured.
What sealant do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Can I choose the sealant colour?
Normally, yes. White, clear and grey are common, and other colours are available for many products, and we agree the colour with you before work begins.
Can new sealant go over the old?
No. Fresh sealant doesn’t stick to old sealant, and it traps any mould or water underneath. We remove it all first.
Can you give us a record of the work?
Yes. When the job is done, we give you the locations and products. Tell us if your assessor needs it in a particular format.
Do I have to be there?
That depends on where the joints are. For work indoors, someone needs to let us in.
Aftercare tips
A little care helps the new joints last. We recommend:
- Store the list of sealed gaps with your building paperwork
- Ask every contractor to reseal any fire stopping they disturb
- Check risers, ceiling voids and cupboards during building checks
- Keep photos of seals that will be hidden
Avoid covering a sealed gap with anything that is not part of the tested detail. Repairs should use a matching fire-rated product. Ask us if you’re not sure which product was used.
A flagged gap shouldn’t wait for the next assessment. Have it sealed, then keep the record.
The process
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes anything from a few hours to several days, depending on how many gaps there are. Parking in a town like Horndean is generally straightforward, but tell us if there’s a driveway or any restrictions, and mention if the work is upstairs, in a flat or high on the outside.
- We go through the gaps on your list or survey and check each one’s size and substrate.
- Anything that is not fit for the job comes out, and the gap is cleaned.
- Backing or fill is fitted where the product’s tested detail calls for it.
- The sealant goes in to the depth its detail sets, then it’s tooled off.
- Finally, we list where we worked and what we used, for your records.
Before we arrive
- For indoor joints, keep the area dry beforehand if you can
- Let us know if you’ve seen damp or leaks
- Tell us about access, such as stairs, a lift or high-level joints

Can I do it myself?
If you are 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 doesn’t work out, we can still put it right.
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.
Work for landlords, hotels and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can be quoted together.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
