Yes, Sidcup is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or send us an email with a few details of the job.
I let a flat near Sidcup station. Can you help?
Yes, we work for letting agents and landlords. Just call 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear price.
Can you give us a record of the work?
Yes. You get a list of where we worked and what we used to keep with your fire safety documents.
Can you do several jobs on one visit?
Yes. Several rooms, windows or areas can go on one quote.
How long will you be here?
It depends on the size of the job, but as a guide it takes anything from a few hours to several days, depending on how many gaps there are. We will tell you when we quote.
Do you carry out fire risk assessments?
No. Your fire risk assessor, designer or building control decides that. Our job is applying the sealant to their specification.
Do you have insurance?
Yes, we’re fully insured.
Do I have to be there?
That depends on where the joints are. For work indoors, someone needs to let us in.
Fire rated sealant in Sidcup
We do not assess buildings or decide what fire stopping is needed; your assessor, designer or building control sets that out. What we do is apply the right product to that specification, properly and neatly. If you have sealant items on a fire risk assessment action list and seals cut through by electricians, plumbers or data installers, we can put it right, on linear gaps, pipe & cable gaps and flats & HMOs alike.
London blocks of flats carry pipes and cables through walls and floors in their common parts and service risers. In Sidcup, building managers may need both fire-rated sealant around those openings and new sealant in shared washrooms.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

When something else is needed
We’d rather tell you now than do work that won’t last, so these are the limits:
- Doors that aren’t fire doors in the first place
- Openings too large for sealant, which need batts, boards or another system
- A wall that isn’t a fire-resisting element to begin with
If you are not sure, just ring 0345 464 0079 or drop us an email and we’ll give you a straight answer before you book.
Surfaces we seal
- Flats & HMOs
- Service penetrations
- Pipe & cable gaps
- Door frames
- Linear gaps
- Plasterboard & masonry
How to look after the new joints
A little care helps the new joints last. We recommend:
- Look in service cupboards and ceiling voids from time to time
- Ask which product was used before you paint
- Store the list of sealed gaps with your building paperwork
- Never patch a fire seal with standard sealant
File the record of locations and products with your fire safety paperwork. It saves time at the next inspection or assessment.
Small gaps around services are simple to deal with while there are only a few. Over time, more work adds more holes and the job gets bigger.
Surface by surface
Door frames
The gap between a door frame and the wall around it needs sealing as well as the door itself. We seal that gap with a fire-rated sealant suited to the frame and wall.
Linear gaps
A linear joint may need to allow for movement as well as fire. The product and depth are chosen to suit both.
When to call us in Sidcup
Buildings are refitted and reconfigured over the years. Conversions to flats and HMOs, and office refits, create new walls and new routes for services, with gaps to match.
The problems people usually mention when they call include:
- Gaps where walls meet ceilings or slabs
- Cracked or shrunken fire-rated sealant
- Ordinary sealant used where a fire-rated product was needed
- Fire stopping disturbed by later work
Letting a property close to Sidcup station? Then fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

Why act early in Sidcup
For some gaps, sealant is not the right answer and another system is needed. Big openings, bundles of cables and plastic pipes may need batts, collars or wraps instead. We will say so if a gap needs something other than sealant. Converted houses in London often have a bathroom above someone else’s living room, and a slow leak from a failed seal can end up in the flat below. Putting it right early is much less trouble.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote and we will talk you through it.

- We leave the area clean and tidy

What happens on the day
Most of a good job is in the preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it usually takes from a few hours to a few days, depending on the number of gaps and the access. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Sidcup. A visitor permit or a nearby bay makes the visit run more smoothly.
- 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 and the faces cleaned.
- The specified fire-rated sealant goes in over any backing its detail requires.
- Every location is recorded with the product used for your records.
Getting ready for the visit
- Mention any sign-in or site rules at work premises
- Mention any parking rules near the property
- Let us know about earlier repairs to the joints

Advice
Can I do it myself?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
What fire rated sealant looks like in Sidcup
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. Commercial buildings in London often have strict access rules and limited loading, so out-of-hours working can be arranged where needed.
Schools such as Birkbeck Primary School are buildings too, and service openings in fire-resisting walls need checking after any refurbishment. Sidcup is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.
