About our fire rated sealant in Felden
We often work from an action list drawn up by a fire risk assessor. If you share the list, we can quote for the gaps that need fire-rated sealant. If you’re dealing with standard silicone or caulk in a fire-stopping gap and gaps left after a refit or conversion, we can put it right, whatever the surface.
For a pub, café, guest house or shop in or near Felden, its washrooms and kitchen need the same sealant care as any big building.
Big or small, it’s backed by our 12-month guarantee in Felden and across Hertfordshire.

Can I do it myself?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
What we are called out for in Felden
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.
Most people get in touch after spotting one of these:
- Open gaps behind door architraves
- Joints picked up in a fire-stopping survey
- Linear gaps at the head of walls
- Open holes round services passing through fire walls
If you look after a church, hall or community building such as Church of St Mary, service openings in its walls need the right fire-rated sealant, as in any building.
Questions to ask before booking
- Which sealant they’ll use, and why
- How long the guarantee is
- When the joint can take water or movement
- How much experience the applicator has
How we quote for fire rated sealant
We do not publish a price list, because jobs vary so much. The quote depends on:
- Whether there’s mould to deal with
- Working hours on commercial sites
- How easy the joints are to reach
- The number of rooms or windows
The cost depends on the size of the job, how much old material has to come out and how easy the joints are to reach. You’ll have a clear quote before any work starts, so you know where you stand.
What to tell us for a quote
You do not need to know the technical terms. Just tell us:
- If someone has resealed it before
- Photos by email, if that is easy
- If it’s domestic, commercial or a hotel
- How many joints, rooms or windows are involved
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is. When it suits you, call 0345 464 0079 or send us an email.
What we cannot put right
In fairness, there are a few things sealant won’t fix:
- Construction that does not provide fire resistance on its own
- Problems with the door itself rather than the gap around the frame
- Issuing a fire rating or certificate for a building
Not sure which it is? You can ring 0345 464 0079 or send us an email and we will tell you honestly.
Joints and surfaces we work on
- Linear gaps

Why it’s worth doing now in Felden
If an assessor has flagged gaps, it makes sense to close them before the next review. Getting them done and written up gives you evidence that the item was dealt with. In a smaller place like Felden, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part.
Why Felden customers choose us
- Anti-fungal silicone where joints get wet
- 20+ years of sealant experience
- Homes, businesses and hotels
- Tidy, careful work

Commercial buildings in Felden
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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details. Hemel Hempstead, which Felden is part of, is one of England’s post-war new towns. Like the other new towns, Hemel Hempstead was planned with its own areas for industry and business, so there are offices, units and workplaces not far from home. Each has washrooms, kitchens and fire-rated joints to keep in order.
For landlords with property near Apsley station, any gap left by new services in shared walls should be closed with a fire-rated product. For site and facilities teams at buildings such as Nash Mills Church of England Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices.

How it works
At the end, we look at the finished work together. The visit itself usually takes from a few hours to a few days, depending on the number of gaps and the access, depending on how much there is to do. For a job in Felden, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- Before starting, we go through the specification or action list with you.
- 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.
- The specified fire-rated sealant goes in over any backing its detail requires.
- Every location is recorded with the product used for your files.
Getting ready for the visit
- Let us know about parking restrictions
- Keep children and pets away from the work area
- Mention any sign-in or site rules at work premises

Advice
Questions from Felden
Do you cover smaller places like Felden?
Yes, Felden is covered. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can you do fire rated sealant in Felden?
Yes. We work across London and the South East, and Felden is part of that. Just ring 0345 464 0079 or email us with a few details of the job, and we’ll send you a clear quote.
Will there be a smell?
That depends on the sealant. Some smell for a while, some hardly at all.
Will you leave a mess?
We keep the work tidy. We protect what’s around the joints, and the area is left clean when we finish.
Is it OK to seal over old sealant?
No. New silicone will not bond to old silicone, and it traps any mould or water underneath. It all has to come out first.
Do you have insurance?
Yes. We are fully insured, with over 20 years’ experience in sealant work.
How do I get a quote for fire rated sealant in Felden?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Do you carry out fire risk assessments?
No. Your fire risk assessor, designer or building control decides that. We apply fire-rated sealant to the requirements they set.
Aftercare tips
Once the sealant has cured, a few habits help it last:
- Look in service cupboards and ceiling voids from time to time
- Flag any open gap you spot round a pipe or cable
- Don’t paint over fire sealant until it has cured
- Keep the record of products and locations with your fire safety documents
Keep the record we give you with the building’s fire safety documents. It helps whoever checks the building next.
A flagged gap shouldn’t wait for the next assessment. Have it sealed, then keep the record so the item can be closed.
