Fire rated sealant for homes and businesses in Bulbourne
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. We check the size and the substrate before choosing the product, then apply it to the depth its tested detail calls for. We work on plasterboard & masonry, service penetrations and pipe & cable gaps, and people most often call us about joints picked up in a fire-stopping survey and open gaps behind door architraves.
Work in a small place like Bulbourne is planned ahead, journey included, so it can be fitted around guests, customers or events where possible.
All our work is covered by a one-year guarantee, wherever you are in Hertfordshire.

The process
On the day, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before any work starts. The work usually takes anything from a few hours to several days, depending on how many gaps there are. Somewhere like Bulbourne needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We go through the gaps on your list or survey and check each one’s size and substrate.
- Old or unsuitable sealant is cut out and the gap cleaned.
- 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.
- We record the locations and products used for your records.
Preparing for the visit
- Mention if the joints have been sealed before
- Keep pets and children clear of the area while we work

Looking after it afterwards
Joint life depends on how it’s used and looked after. We suggest:
- Tell trades working in the building that fire seals must be put back
- Take pictures of fire stopping before ceilings or boxing go back
- Flag any open gap you spot round a pipe or cable
- Check risers, ceiling voids and cupboards during building checks
Don’t add foam, filler or ordinary sealant over a fire seal. Repairs should use a matching fire-rated product. We can tell you which product we used.
When you plan work that goes through walls or ceilings, plan the fire stopping too. Doing it at the time avoids leaving gaps behind.

Fire rated sealant around Bulbourne
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 work to the specification you’re given, installing the product to its tested details.
Community buildings like St Mary's Church are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking. For site and facilities teams at buildings such as Grove Road Primary School, service openings in fire-resisting walls need checking after any refurbishment.

Surface by surface
Linear gaps
Linear gaps run along the head of walls, at floor edges and between panels. We seal them to the tested detail, with backing where it’s needed.
Door frames
Behind most architraves is a gap between frame and wall. Where it’s open, we seal it to the product’s details for that gap size before the trim goes back.
Landlords, agents and businesses in Bulbourne
Housing providers, facilities teams and property managers book us too in Bulbourne and across Hertfordshire. We can quote a run of properties together, and we are fully insured for the work.
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.
Common problems we fix in Bulbourne
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 particularly when it was the last job before handover.
Common reasons people contact us are:
- Linear gaps at the head of walls
- Seals cut through by electricians, plumbers or data installers
- Gaps around pipes and cables through fire-resisting walls
- Fire seals that have cracked with movement
Letting a property close to Tring station? Then new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.
