What the job involves on each surface
Plasterboard walls
Holes in plasterboard are often cut roughly for services. Where a hole is bigger than the sealant’s tested range, it needs another approach.
Flats and HMOs
Conversions generally leave a mix of old and new service holes. The gaps on your list are sealed with a fire-rated product and the locations noted.
About our fire rated sealant in Kings Langley
We do not assess buildings or decide what fire stopping is needed; your assessor, designer or building control sets that out. Our part is applying the specified sealant carefully, to the right depth and with the right backing. We’re often asked to deal with linear gaps at the head of walls and door frames with gaps between frame and wall, on door frames, plasterboard & masonry and pipe & cable gaps.
Community buildings, schools and small businesses around places like Kings Langley have washrooms and kitchens that see a lot of use. Sealant and fire-rated joints there matter as much as in any larger building.
Big or small, you get the same one-year guarantee.

Workplaces and buildings in Kings Langley
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 let a flat or house near Kings Langley station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. Community buildings like Church of All Saints are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking.

What happens on the day
All our tools and materials come with us in the van, so you do not need to buy or prepare anything. Once we’ve agreed what’s being done, the area is protected and the work begins. Most jobs take from a few hours to a few days, depending on the number of gaps and the access. Parking around Kings Langley is normally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- We go through the gaps on your list or survey and check each one’s size and substrate.
- 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.
- We record the locations and products used for your records.
Before we arrive
- Let us know about parking restrictions

Related advice
Why deal with it now?
An open gap in a fire-resisting wall is a route for smoke and fire. Sealing it properly restores what the wall was there to do, and the work involved is often modest. In a smaller place like Kings Langley, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first and give you a clear quote before any work starts.
Why book with us
- Neat joints and a tidy finish
- Arbo and Everbuild products
- Anti-fungal sanitary silicone in wet areas
- Domestic, commercial and hotel work

DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Common problems we fix in Kings Langley
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 they leave doesn’t always get resealed.
The most common problems we see are:
- Seals cut through by electricians, plumbers or data installers
- Gaps left after a refit or conversion
- Open holes round services passing through fire walls
- Joints picked up in a fire-stopping survey
If you look after a building such as Kings Langley Primary School, service openings in fire-resisting walls need checking after any refurbishment.

How we quote for fire rated sealant
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Working hours on commercial sites
- How much old sealant there is and how hard it is to remove
- How many rooms, windows or areas are involved
- Which sealant suits the joint
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we will explain the quote if you ask.
What to tell us for a quote
Photos help, but a description is a good start. Try to tell us:
- Pictures of the joints, sent by email
- If someone has resealed it before
- What the problem is, such as mould, gaps, leaks or cracking
- How we’d reach the joints
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email photos if that is easy.
