About our fire rated sealant in Bygrave
In flats, HMOs, offices and schools, fire stopping is often disturbed by later work. One new cable or pipe can leave a gap that nobody goes back to seal. We seal them with a product tested for that kind of gap. Common call-outs are for gaps left after a refit or conversion and standard silicone or caulk in a fire-stopping gap, on flats & HMOs, pipe & cable gaps and service penetrations.
In a village or hamlet like Bygrave, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. They all have washrooms, kitchens and service openings that need the right sealant.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

FAQs for Bygrave
Can you help a landlord with a rental near Baldock station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just call 0345 464 0079 or email us with the address and what needs doing, and we will send you a clear quote.
Will you come out to Bygrave?
Yes, Bygrave is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Where are you based?
Our base is Crawley. We work across South East England, London and Scotland.
Do you carry out fire risk assessments?
No. That is for a fire risk assessor, designer or building control. We apply fire-rated sealant to the requirements they set.
Is it messy?
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. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. We remove it all first.
Is standard sealant good enough for a fire gap?
No. A gap that needs fire stopping needs a tested fire-rated product fitted to the maker’s details.
Is there any odour?
Some sealants have a smell while they cure, which fades as it sets. Opening a window helps.
For landlords and businesses
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we will quote.
From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
DIY versus a professional finish
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Different surfaces, different methods
Plasterboard walls
In plasterboard walls, the condition of the board edge matters. Crumbling edges are cleaned back before the sealant goes in.
Door frames
The gap between a door frame and the wall around it needs sealing as well as the door itself. We fill it with a fire-rated product suited to the materials either side.

What we do, step by step
When we arrive, we start by going over the job with you, so there are no surprises. Surfaces next to the work are protected before any work starts. Most jobs take anything from a few hours to several days, depending on how many gaps there are. Somewhere as small as Bygrave, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we work through your list or survey, measuring each gap and checking what it’s formed in.
- We remove any old or unsuitable filler and clean the gap.
- Backing or fill is fitted where the product’s tested detail calls for 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.
Getting ready for the visit
- For business premises, tell us about site rules or sign-in
- Clear items away from the joints we are working on
- Mention any leaks or damp you’ve noticed

How to look after the new joints
A little care helps the new joints last. Our advice:
- Include fire stopping when you schedule refits
- Ask which product was used before you paint
- File the fire-stopping record where your assessor can find it
- Tell trades working in the building that fire seals must be put back
Follow the cure time we give you before decorating over the sealant. Not every fire-rated sealant takes paint, so ask us which we used.
Leave a fire-stopping gap open and smoke can move through the building much more easily. Closing it is generally a straightforward job.
What happens if it’s left?
A quick fill with any sealant to hand is not fire stopping. A fire-rated product only performs as tested when it’s installed to its tested detail, which is why we match the product and the method to each gap. Around Bygrave, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
The cost reflects the work involved, not guesswork. That’s why we ask about the job first and give you a clear price before we start.

Fire rated sealant in Bygrave: local notes
Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, which is often where open fire-stopping gaps are first noticed. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
Schools such as The Knights Templar School are buildings too, and fire-stopping around service openings should be restored whenever new services go in. Community buildings like Church of St Margaret of Antioch are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building.
