How the visit works
The work is kept neat and contained to the joints we’re treating, so you can carry on as normal. The job usually takes from a few hours to a few days, depending on the number of gaps and the access, and we explain the cure time before we leave. Somewhere like Holwell needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We start with the survey or action list, checking the size and surfaces of every gap.
- Old or unsuitable sealant is cut out and the gap cleaned.
- 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.
- Finally, we list where we worked and what we used, for your records.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- Keep children and pets away from the work area
- Clear items away from the joints we’re working on

Advice
Fire rated sealant in Holwell, done properly
Fire-rated sealant closes the gaps around pipes, cables and frames where they pass through a fire-resisting wall or floor. Each gap is sealed to the product maker’s tested detail for its size and substrate, and we can record what went where. If you have fire seals that have cracked with movement and fire stopping disturbed by later work, we can help, whatever the surface.
For holiday lets, converted business premises or a community building near Holwell, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.
You are covered for a year from the day we finish. If anything is not right with it, phone 0345 464 0079 or send us an email.

How we quote for fire rated sealant
You’ll get a clear quote before work begins. It’s based on:
- When we can work, for business premises
- The amount of work
- Whether the work is at height
- Whether there’s mould to deal with
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. The price is agreed before we begin.
Asking for a quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- The problem you’ve noticed
- If someone has resealed it before
- Where the job is, and your postcode
- Photos by email, if that’s easy
Every job is quoted individually, so start by telling us what you need. Simply ring 0345 464 0079 or email us and describe the job and send pictures if you have them.
Landlord and commercial work in Holwell
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
DIY sealant or a professional job?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
How to look after the new joints
No joint lasts for ever, but care makes a real difference. Our tips:
- Keep photos of seals that will be hidden
- Keep the record of products and locations with your fire safety documents
- Do not paint over fire sealant until it has cured
- Tell trades working in the building that fire seals must be put back
Let contractors know where fire stopping has been done, and make sure anything they disturb is resealed with a suitable product. A lot of damaged fire stopping comes from later work.
An open gap isn’t only a fire issue: they also let noise, draughts and sometimes pests through. Dealing with them early helps with all of these.
Common questions in Holwell
Will you come out to Holwell?
Yes, Holwell is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you work for landlords with property near Hitchin station?
Yes, we work for landlords and letting agents. Just phone 0345 464 0079 or email us and tell us about the property, and we will give you a clear quote.
Will you leave a mess?
We keep the work tidy. We protect what’s around the joints, and we clear up when we are done.
Do you carry out fire risk assessments?
No. That’s for a fire risk assessor, designer or building control. Our job is applying the sealant to their specification.
Can ordinary silicone be used in a fire-stopping gap?
No. It might close the gap, but it is not a fire-rated seal. A tested fire-rated product is needed, or ask us to do it.
How long does fire rated sealant take?
Typically it takes anything from a few hours to several days, depending on how many gaps there are. Bigger jobs take longer.
Will we have a record of what was sealed?
Yes. When the job is done, we give you the locations and products. Tell us if your assessor needs it in a particular format.
Where are you based?
We work from Crawley. Our applicators cover Holwell.
Do you need fire rated sealant in Holwell?
Many open fire-stopping gaps are made after the building is finished. New cables, pipes and data runs go through walls and ceilings and the hole round the new service isn’t always sealed again.
Any of these means the joints need attention:
- Old fire sealant that has split or come away
- Gaps filled with a product that isn’t fire-rated
- Linear gaps at the head of walls
- Sealant items on a fire risk assessment action list
For site and facilities teams at buildings such as The Priory School, service openings in fire-resisting walls need checking after any refurbishment.
What your quote should include
- Is VAT in the price?
- How the joint is cleaned and prepared
- How the colour is chosen
- Whether they’re fully insured
Commercial buildings in Holwell
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, and gaps around services are often picked up there. 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 Church of St Peter (C of E) at Corner with Holwell Road, older buildings that have had new heating or wiring often have service gaps worth checking. Letting a property close to Hitchin station? Then fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

Different surfaces, different methods
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.
Plasterboard walls
In plasterboard walls, the condition of the board edge matters. Loose material is removed so the sealant has a firm edge.
