How we handle fire rated sealant in Marchwood
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 old fire sealant that has split or come away and gaps left after a refit or conversion, we can put it right.
Community buildings, schools and small businesses around places like Marchwood have washrooms and kitchens that see a lot of use. Sealant and fire-rated joints there matter as much as in any larger building.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

What sealant work cannot fix
In fairness, some problems need a different trade:
- Big openings where sealant alone isn’t the tested solution
- Assessing a building’s fire safety
- Construction that doesn’t provide fire resistance on its own

The process
There’s no need to move everything out, just the space around the work. Everything nearby is protected, and the job takes anything from a few hours to several days, depending on how many gaps there are in most cases. Parking around Marchwood is usually easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- Before starting, we go through the specification or action list with you.
- Each gap is measured and its substrate and service noted.
- Any non-fire-rated filler is removed and the faces cleaned.
- We fit backing where needed and apply the fire-rated sealant to depth.
- Every location is recorded with the product used for your records.
How to prepare
- Mention any leaks or damp you’ve noticed
- Let us know about parking restrictions
- For business premises, tell us about site rules or sign-in

Marchwood questions
Is Marchwood in your area for fire rated sealant?
Yes. We work across London and the South East, and Marchwood is part of that. You can call 0345 464 0079 or email us and tell us what needs doing, and we will give you a clear price.
Do you work for landlords with property near Millbrook (Hants) station?
Yes, landlords and agents are among the people we work for. Just ring 0345 464 0079 or drop us an email with the address and what needs doing, and we will give you a clear quote.
Do you remove the old sealant?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
Do you work in flats, HMOs and commercial buildings?
Yes. We regularly work in flats, HMOs, schools and offices while they’re in use. Out-of-hours work can be arranged where it’s needed.
Can you seal over the old sealant?
No, because it fails. The old sealant always comes out first, so the new sealant bonds properly.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
What do you put in the joint?
Products from Arbo and Everbuild, among others, picked for each joint. We’ll tell you what we are using and why.
Can ordinary silicone be used in a fire-stopping gap?
No. Ordinary silicone, caulk or foam isn’t tested as fire stopping. We cut it out and reseal with a fire-rated product.
What affects the cost of fire rated sealant
We quote each job individually. This is what makes a difference:
- The type of sealant required
- Whether there’s mould to deal with
- Access and height
- How many areas need sealing
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
Helping us quote
Photos by email are helpful but not essential. Please mention:
- Roughly how big the job is
- The address or postcode of the job
- If it’s domestic, commercial or a hotel
- What the problem is, such as mould, gaps, leaks or cracking
Every job is quoted individually, so start by telling us what you need. Simply call 0345 464 0079 or drop us an email and describe the job, and photos are welcome.
Leave it or put it right?
If an assessor has flagged gaps, it makes sense to close them before the next review. Having them sealed and recorded now means you can show the action was taken. Homes in smaller places like Marchwood 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.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please phone 0345 464 0079 or send us an email and we’ll talk you through it.

Fire rated sealant in Marchwood: local notes
For seaside hotels, guest houses and holiday lets around Marchwood, heavy use in the busy months is hard on washroom and kitchen sealant, and any building work there should leave fire-rated joints made good. 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 work to the specification you’re given, installing the product to its tested details.
Rented homes near Millbrook (Hants) station change hands often, and new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. Community buildings like Church of St John the Apostle are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building.

How the job changes by surface
Linear gaps
Linear gaps run along the head of walls, at floor edges and between panels. We seal them to the tested detail, with backing where it’s needed.
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.
DIY sealant or a professional job?
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 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 getting the depth right matters as much as the look.
Common problems we fix in Marchwood
A lot of fire stopping is out of sight: in ceiling voids, service risers and behind boxing. Because nobody sees it, gaps go unnoticed until an assessor or surveyor looks.
It’s worth asking for a quote if you see:
- Cracked or shrunken fire-rated sealant
- Open holes round services passing through fire walls
- Sealant items on a fire risk assessment action list
- Gaps left after a refit or conversion
Schools such as Marchwood Junior School are buildings too, and service openings in fire-resisting walls need checking after any refurbishment.
What your quote should include
- Who does the work, and how experienced they are
- When the joint can take water or movement
- Whether all the old sealant comes out first
- Whether the sealant suits the joint
