Your questions about fire rated sealant in Rudmore
Do you work for hotels and guest houses in Rudmore?
Yes. Hotel and guest-house work is part of what we do. Work can be planned room by room, and out-of-hours working can be arranged.
Can you help a landlord with a rental near Portsmouth & Southsea station?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before work begins.
Can you seal over the old sealant?
No, and we never do. It may look fine at first, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Will the old sealant be removed?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
What do you need from me for a quote?
Just the basics: where it is, what you’ve noticed and how we reach it. Then phone 0345 464 0079 or drop us an email.
What sealant do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference.
Do you hold any approvals?
Yes. We’re approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
Do you work in Rudmore?
Yes. We cover Rudmore, as part of our work across South East England, London and Scotland. To book, call 0345 464 0079 or send us an email.
Fire rated sealant for homes and businesses in Rudmore
A gap around a door frame, a linear joint at the head of a wall and a hole round a pipe are each sealed differently. Measuring the gap and checking what it’s made of comes first, then apply it to the depth its tested detail calls for. Typical jobs include gaps around pipes and cables through fire-resisting walls and gaps filled with a product that isn’t fire-rated, across pipe & cable gaps, flats & HMOs and linear gaps.
If you run a pub, café, guest house or shop in or near Rudmore, its washrooms and kitchen need the same sealant care as any big building.
You get a one-year guarantee, the same in Rudmore as everywhere else we work.

When to call us in Rudmore
If the sealant is too shallow, has the wrong backing or sits on a dusty surface, it is not installed as tested. We see plenty of fire stopping that was hurried.
Keep an eye out for these signs:
- Gaps where walls meet ceilings or slabs
- Cracked or shrunken fire-rated sealant
- Joints picked up in a fire-stopping survey
- Door frames with gaps between frame and wall
Rented homes near Portsmouth & Southsea station change hands often, and new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

Surface by surface
Plasterboard walls
Many fire-resisting walls in flats, offices and conversions are plasterboard. The sealant has to be one tested in plasterboard.
Flats and HMOs
In flats and HMOs, the walls and floors between homes and common areas need sealing where services pass through. We work through the gaps on your assessment room by room.
When something else is needed
New sealant can’t fix everything, and we’ll tell you before any work starts. Sealant won’t put right:
- Construction that does not provide fire resistance on its own
- Fire doors that need new seals, closers or hardware
- Certifying a building or signing off its fire safety
If you’re not sure, just call 0345 464 0079 or drop us an email and we’ll give you a straight answer before booking.

What affects the cost of fire rated sealant
You will get a clear quote before work begins. It takes into account:

- How many rooms, windows or areas are involved

Combining jobs into one visit is generally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear price for the lot.

What we do, step by step
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, carry out the job and tidy away. Most jobs take a few hours for a handful of gaps, and longer for a whole building. For a job in Rudmore, 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.
- 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 and the gap cleaned.
- The specified fire-rated sealant goes in over any backing its detail requires.
- Every location is recorded with the product used for your files.
Before we arrive
- Let us know about parking restrictions
- Try not to wet indoor joints just before the visit
- On commercial sites, let us know about site rules
How to get a quote
We do not publish a price list, because every job is different. Instead, your job gets its own clear quote. To get started, ring 0345 464 0079 or email us.

Commercial buildings in Rudmore
If you run a hotel, guest house or holiday let in a coastal place like Rudmore, 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.
Managing a site like The Flying Bull Academy? Then gaps opened by contractors for new cabling are a common finding in schools and offices.

Why act early in Rudmore
Waiting for the next refit can leave a gap open for years. Sealing the gap now is a contained job on its own and needn’t wait for anything else. In a smaller place like Rudmore, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
What it costs depends on the amount of work, how hard the old material is to remove and access to the work. We give a clear quote before any work starts, so you know where you stand.

Can I do it myself?
If you’re set on DIY, put the effort into 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.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.
