Questions from Clothall
Is Clothall in your area for fire rated sealant?
Yes, Clothall is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or email us with a few details of the job, and we’ll send you a clear quote.
Is Clothall within the area you cover?
Yes, Clothall is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Do you certify the fire stopping?
We don’t give ratings or certificates for our work. Your specification sets the requirement, and we fit a product whose tested details meet it.
Can ordinary silicone be used in a fire-stopping gap?
No. It looks sealed but will not perform as fire stopping. A tested fire-rated product is needed.
Will you assess my building’s fire safety?
No. Your fire risk assessor, designer or building control decides that. Our job is applying the sealant to their specification.
Can tenants book the work?
Yes, but check with your landlord or agent first. Landlords are often happy for the work to be arranged.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Do I need to be at home?
If the work is inside, we need someone to let us in. Once we’ve agreed the job, you don’t need to watch us work.
Fire rated sealant in Clothall, done properly
We can work through a building room by room or floor by floor, with each location and product recorded. It gives you a list to keep with the building’s fire safety documents. If you have unsealed gaps around fire door frames and unsealed gaps where pipes and cables go through a wall, we can put it right, whatever the surface.
If you have holiday lets, a converted barn used for business or a community building near Clothall, the washrooms, kitchens and any fire-rated joints need the same care as a big site.
You get a one-year guarantee, the same in Clothall as everywhere else we work.

How to look after the new joints
Simple care keeps the joints in good condition. Our advice:
- Include fire stopping when you schedule refits
- Check risers, ceiling voids and cupboards during building checks
- Keep general-purpose foam and caulk away from fire-stopping gaps
- Take pictures of fire stopping before ceilings or boxing go back
Don’t drill through or remove a fire seal without putting it back properly. If you need new services through a sealed wall, plan the fire stopping as part of the job.
Leave a fire-stopping gap open and smoke can move through the building much more easily. Closing it is normally a straightforward job.
How it works
A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, do the work and clear up. Most jobs take a few hours for a handful of gaps, and longer for a whole building. For a village or hamlet like Clothall, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- 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.
- We fit backing where needed and apply the fire-rated sealant to depth.
- Every location is recorded with the product used for your files.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any sign-in or site rules at work premises

More services for Clothall
Do you need fire rated sealant in Clothall?
Over time, buildings change layout and use. A house turned into flats or an HMO, or an office split into smaller units, brings new walls, new service routes and new gaps.
Look out for these signs:
- Damaged fire sealant left by other trades
- Fire seals that have cracked with movement
- Door frames with gaps between frame and wall
- Open holes round services passing through fire walls
For buildings such as Church of St Mary, gaps around pipes and cables are worth checking after any building work there.
Questions to ask before booking
- What guarantee comes with the work
- Who turns up on the day
- When the joint can take water or movement
- How the surfaces are prepared before sealing
Different surfaces, different methods
Door frames
Frame gaps are normally 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.
Flats and HMOs
Flats and HMOs rely on fire separation between homes and the common parts. We work through the gaps on your assessment, flat by flat if needed.
Workplaces and buildings in Clothall
Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, and gaps around services are often picked up there. We work to the specification you’re given, installing the product to its tested details.
For site and facilities teams at buildings such as Weston Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices. Rented homes near Baldock station change hands often, and any gap left by new services in shared walls should be closed with a fire-rated product.

When it is not the sealant
New sealant cannot fix everything, and we’ll tell you before we start. Sealant will not put right:
- Problems with the door itself rather than the gap around the frame
- Deciding what fire stopping a building needs
- Issuing a fire rating or certificate for a building
If you’re not sure, just phone 0345 464 0079 or drop us an email and we will give you a straight answer before you book.

DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
Why act early in Clothall
Fire-rated sealants need more care than everyday sealant. How it’s installed changes how it performs, so we follow the maker’s details on every gap. Older cottages and farmhouses around Clothall can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
We do not show prices on the website, because each job is priced on what it involves. For a quick quote, please ring 0345 464 0079 or drop us an email.
