Workplaces and buildings in Downe
Many London buildings have tight access and loading restrictions, so out-of-hours working can be arranged where needed. 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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
Community buildings like St Mary's Church are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building. Managing a site like Downe Primary School? Then service openings in fire-resisting walls need checking after any refurbishment.

About our fire rated sealant in Downe
Deciding which gaps need fire stopping isn’t our role; 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 sealant items on a fire risk assessment action list and open joints along the top of partitions, we can help.
Commercial work in London comes with its own logistics: loading restrictions, building rules and tight access. Timings and access are agreed with the building before work starts in Downe.
Every job is covered by a one-year guarantee, wherever you are in Greater London.

Can I do it myself?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
How to look after the new joints
No joint lasts for ever, but care makes a real difference. Our tips:
- Look in service cupboards and ceiling voids from time to time
- Get damaged fire seals looked at promptly
- Keep photos of seals that will be hidden
- Store the list of sealed gaps with your building paperwork
Keep the record we give you with the building’s fire safety documents. It helps whoever checks the building next.
Small gaps around services are simple to deal with while there are only a few. Leave them and each new job adds another hole and the job gets bigger.
What happens if it’s left?
A quick fill with any sealant to hand is not fire stopping. Fire-rated products are tested in set gap sizes, depths and substrates, so both the product and the method matter. In a flat in Downe, failed sealant seldom stays inside your own four walls: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.

Is parking a problem for a job in Downe?

Yes. All our work carries our 12-month guarantee.

Related advice
What we are called out for in Downe
Sometimes the wrong product was used from the start: ordinary expanding foam, standard silicone or decorators’ caulk in a place that needed a tested fire seal. It looks sealed, but it is not fire-rated.
Any of these means the joints need attention:
- Gaps where walls meet ceilings or slabs
- Gaps filled with a product that isn’t fire-rated
- Unsealed gaps where pipes and cables go through a wall
- Sealant items on a fire risk assessment action list
As a London address, Downe can be tricky for parking: let us know about parking bays, permits or a driveway.

Work for landlords, hotels and businesses
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements.
