A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
Fire rated sealant for homes and businesses in Hackbridge
We do not assess buildings or decide what fire stopping is needed; that comes from your fire risk assessor, designer or building control. What we do is apply the right product to that specification, properly and neatly. If you are dealing with gaps left after a refit or conversion and gaps where walls meet ceilings or slabs, we can help, on linear gaps, door frames and service penetrations alike.
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 Hackbridge, that can mean fire-rated sealant around service openings as well as resealing in shared washrooms and kitchens.
You get a one-year guarantee, the same in Hackbridge as everywhere else we work.

Commercial buildings in Hackbridge
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 work to the specification you are given, installing the product to its tested details. Many London buildings have tight access and loading restrictions, and out-of-hours working is possible to arrange.
Letting a property close to Mitcham Eastfields station? Then any gap left by new services in shared walls should be closed with a fire-rated product. If you look after a building such as St Thomas of Canterbury Catholic Primary School, service openings in fire-resisting walls need checking after any refurbishment.
Hackbridge is about 2 miles west of Thornton Heath, in Greater London. Jobs in Hackbridge get the same care as everywhere else we work: the old material taken out, joints prepared properly and a 12-month guarantee. Hackbridge is one of 764 places in Greater London we cover. We also work in London, around 7 miles away.
We work across the CR4, SW16 and SM4 postcode area for fire rated sealant and the streets around it. Whether your property is on Kings Road, Baker Lane and Manor Road or a nearby road, we can help. We also cover the places around Hackbridge: Mitcham (1 mile north), Eastfields (1 mile north), Colliers Wood (1 mile north-west), Merton Abbey (2 miles north-west) and Furzedown (2 miles north).

Local landmarks in Hackbridge
We work in homes and buildings around The White Lion of Mortimer pub, The Archbishop Lanfranc School and St Mark's Church of England Academy and the streets around them. The nearest railway station is Mitcham Eastfields station, roughly 0.5 miles north of the centre. Nearby you’ll also find Wandle Industrial Museum (0.7 miles west) and Wilson Hospital (0.5 miles south-west). Not far away are Duppas Hill and Cranmer Green.
Should I try it myself first?
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Hackbridge: your questions answered
Do you cover Hackbridge for fire rated sealant?
Yes, Hackbridge is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or send us an email and tell us what needs doing, and we will send you a clear quote.
Is parking a problem for a job in Hackbridge?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly.
What should I tell you?
The location, the problem and the rough size of the job. Photos by email help too.
Do you guarantee your work?
Yes: twelve months. If there’s a problem with our work in that time, tell us and we will put it right.
Where are you based?
We’re based in Crawley, West Sussex, and we work across South East England, London and Scotland.
What does intumescent mean?
An intumescent sealant expands when it gets hot. It’s one type of fire-rated sealant; the right one depends on the gap and what passes through it.
Which products do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference.
What fire rating will the seal have?
That isn’t something we state or certify. The requirement comes from your assessor, designer or building control, and we fit a product whose tested details meet it, recording the locations and products.
The process
We bring everything the job needs with us, so you don’t need to buy or prepare anything. After a quick look at the joints together, the area is protected and the work begins. It normally takes from a few hours to a few days, depending on the number of gaps and the access. In a London area like Hackbridge, the main things to plan are parking and access: let us know about parking, the floor we will be working on and any lift or shared entrance.
- We plan the order of work and access, floor by floor or flat by flat.
- We take out any damaged or unsuitable sealant.
- Dust and loose debris are cleaned from each gap.
- We apply and tool the sealant to the product’s tested detail.
- We record what was done and flag anything that needs a different system.
Getting ready for the visit
- Let us know about stairs, lifts or work at height
- Plan for the work area to be out of bounds to pets and children
- Mention if the joints have been sealed before

Related advice
Signs you need fire rated sealant in Hackbridge
Door frames are a common weak spot. The gap between the frame and the wall is hidden behind the architrave, so it’s easy to leave unsealed when doors are changed.
The most common problems we see are:
- Seals cut through by electricians, plumbers or data installers
- Standard silicone or caulk in a fire-stopping gap
- Gaps around pipes and cables through fire-resisting walls
- Gaps flagged on a fire risk assessment
Hackbridge is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.
What your quote should include
- Whether they’re fully insured
- Is VAT in the price?
- How the joint is cleaned and prepared
- What happens if they find a problem under the old sealant
Different surfaces, different methods
Flats and HMOs
Converted houses often have gaps around old and new services. We seal the ones on your specification with a tested product.
Linear gaps
Long, narrow gaps appear where walls meet slabs and ceilings. They’re sealed with a fire-rated sealant over backing where the detail calls for it.
What affects the cost of fire rated sealant
Call for a quick quote. The main things that affect it are:
- How much there is to do
- How many areas need sealing
- Access and height
- The old material and how stubborn it is
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, plus any working-time requirements on site. Call for a quick quote and we will go through it with you.
