When to call us in Penge
Gaps around door frames are easily missed. The architrave hides the gap between frame and wall, so it’s easy to leave unsealed when doors are changed.
The problems people generally mention when they call include:
- Standard silicone or caulk in a fire-stopping gap
- Unsealed gaps around fire door frames
- Holes left by a change of layout
- Unsealed gaps where pipes and cables go through a wall
For buildings such as Church of St John the Evangelist, older buildings that have had new heating or wiring often have service gaps worth checking.

How we handle fire rated sealant in Penge
Filling a fire-stopping gap with standard silicone or caulk doesn’t make it fire-rated. We cut out the wrong material and the gap is resealed with a product tested for that use. We work on service penetrations, door frames and flats & HMOs, and people most often call us about sealant items on a fire risk assessment action list and open holes round services passing through fire walls.
In London’s blocks of flats, service risers and common parts have pipes and cables passing through walls and floors. For managing agents and building owners in Penge, that can mean fire-rated sealant around service openings as well as resealing in shared washrooms and kitchens.

Common questions in Penge
Can parking be tricky for a visit in Penge?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. That way the visit can be planned around it.
Do you work for hotels and guest houses in Penge?
Yes, hotels and guest houses are among the places we work. Rooms can be done a few at a time, so the building stays open.
Will there be a smell?
Possibly a little. It fades as the sealant cures.
Do I need to be at home?
We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.
Can ordinary silicone be used in a fire-stopping gap?
No. A gap that needs fire stopping needs a tested fire-rated product fitted to the maker’s details.
What do you put in the joint?
Products from Arbo and Everbuild, among others, picked for each joint. We will tell you what we’re using and why.
Can you tell me how many minutes the seal will last?
That isn’t something we state or certify. Your specification sets the requirement, and we apply a product tested for it.
Do you provide details of the products used?
Yes. When the job is done, we give you the locations and products. If you need pictures or a set layout, ask when you get a quote.
What fire rated sealant looks like in Penge
Many London buildings have tight access and loading restrictions, so out-of-hours working can be arranged where needed. 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.
Penge is in London, so parking needs planning: let us know about parking bays, permits or a driveway. If you let a flat or house near Penge West station, any gap left by new services in shared walls should be closed with a fire-rated product.

Should I try it myself first?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
What the job involves on each surface
Service penetrations
A copper pipe, a cable and a plastic pipe can all need different fire-stopping details. We follow the manufacturer’s tested detail for each.
Door frames
Our work is the joint between frame and wall. The door leaf, its seals and closer need a door specialist, and we will say if we spot a problem with them.
Why deal with it now?
Paying for fire stopping that has to be redone is a false economy. If the details weren’t followed, the seal may need redoing once someone inspects it. Converted houses in London often have a bathroom above someone else’s living room, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Dealing with it early is far simpler for homes in Penge.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.
Why us?
- Anti-fungal silicone where joints get wet
- We never seal over old sealant
- Over 20 years’ experience
- An ARBOMaster approved applicator

How it works
There’s no need to move everything out, just the space around the work. Everything nearby is protected, and the job takes a few hours for a handful of gaps, and longer for a whole building in most cases. For a job in Penge, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.
- 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.
- Finally, we list where we worked and what we used, for your records.
Preparing for the visit
- Mention any parking rules near the property
- Mention if the joints have been sealed before
- Mention any sign-in or site rules at work premises
