About our fire rated sealant in Hoe Gate
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. If you have linear gaps at the head of walls and cracked or shrunken fire-rated sealant, we can help, on pipe & cable gaps, plasterboard & masonry and service penetrations alike.
For a small place like Hoe Gate, the journey and timings are agreed in advance, so it can be fitted around guests, clients or events where possible.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

Surface by 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.
Door frames
Our work is the joint between frame and wall. Doors, seals and closers are for a door specialist and we will mention anything we notice.
How we quote for fire rated sealant
For a quick quote, just ask. What matters most is:
- Access and height
- Which sealant suits the joint
- Working hours on commercial sites
- Whether old sealant or filler has to be cut out
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are not sure whether it needs doing, call 0345 464 0079 or email us for an honest opinion and a quote.
What we need to know
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- If someone has resealed it before
- Where the job is, and your postcode
- Pictures of the joints, sent by email
- What the problem is, such as mould, gaps, leaks or cracking
For a quick quote, get us on the phone, or send an email if you’d rather. Tell us about the joints that need doing and we will explain what’s involved.

Common questions in Hoe Gate

Where do you work from?

What does fire rated sealant cost?
It depends on the job, so we quote each one individually. To get one, phone 0345 464 0079 or email us and let us know what needs doing and where.
What does intumescent mean?
Intumescent describes a material that swells in heat. Many fire-rated sealants work this way, but not all.
Can you seal over the old sealant?
No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. It all has to come out first.
Is there any odour?
Some sealants have a smell while they cure, which fades as it sets. Opening a window helps.
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Store the list of sealed gaps with your building paperwork
- Make resealing part of every contractor’s brief
- Plan fire stopping into any work that goes through walls or floors
- Ask which product was used before you paint
Don’t add foam, filler or ordinary sealant over a fire seal. Repairs should use a matching fire-rated product. We can tell you which product we used.
Open gaps don’t only matter in a fire: they also let noise, draughts and sometimes pests through. Sealing them early helps on every front.
Fire rated sealant around Hoe Gate
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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
Managing a site like Newtown Soberton Infant School? Then fire-stopping around service openings should be restored whenever new services go in. Community buildings like Church of the Holy Trinity are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking.

For rail, the closest station is Portchester station, roughly 4.5 miles south of the centre. Nearby you will also find Knowle Hospital (4.6 miles south-west). Open spaces near Hoe Gate include St Clair's Meadow and Portsdown Hill.
Why deal with it now?
An unsealed gap lets smoke and fire get round a wall that was built to hold them back. Sealing it properly restores what the wall was there to do, and the sealing itself is often a contained piece of work. Where a wall is exposed, as many are in small places like Hoe Gate, 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: how many joints, what’s in them now and how we reach them. You will know the price before we begin.

How the visit works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes from a few hours to a few days, depending on the number of gaps and the access and we leave things clean and tidy. In a small place like Hoe Gate, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start with the survey or action list, checking the size and surfaces of every gap.
- We remove any old or unsuitable filler and clean the gap.
- Where the tested detail needs backing or fill, we fit it.
- We apply the fire-rated or intumescent sealant to the specified depth and tool it.
- We record the locations and products used for your records.
Before we arrive
- Mention any tricky access
- Mention any leaks or damp you’ve noticed
- Move anything stored near the joints

Signs you need fire rated sealant in Hoe Gate
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 doesn’t always get resealed.
Keep an eye out for any of the following:
- Gaps where walls meet ceilings or slabs
- Ordinary sealant used where a fire-rated product was needed
- Old fire sealant that has split or come away
- Gaps around pipes and cables through fire-resisting walls
Rented homes near Portchester station change hands often, and any gap left by new services in shared walls should be closed with a fire-rated product.

- How the joint is cleaned and prepared
