Fire rated sealant for homes and businesses in Ham
Until it’s heated, intumescent sealant behaves like an ordinary sealant; in a fire it expands into the joint. Which product suits a gap depends on its width, the materials either side and what runs through it, so we follow the tested detail for each one. If you are dealing with damaged fire sealant left by other trades and cracked or shrunken fire-rated sealant, we can help, on pipe & cable gaps, door frames and linear gaps alike.
Commercial work in London comes with its own logistics: loading restrictions, building rules and tight access. For a building in Ham, we agree timings and access before anything starts, and room-by-room programmes can be planned where needed.
We guarantee the work for a year. If something is not right with it in that time, tell us and we will put it right.

When it isn’t the sealant
We will not take on work that will not last, so these are the limits:
- Fire doors that need new seals, closers or hardware
- Big openings where sealant alone is not the tested solution
- Construction that does not provide fire resistance on its own
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we’ll tell you honestly before booking.

Quotes for fire rated sealant in Ham

FAQs for Ham
Do you work for landlords with property near Teddington station?
Yes, we work for landlords and agents. You can call 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before we start.
Do you take on hotel work around Ham?
Yes. Hotel and guest-house work is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.
Can you give us a record of the work?
Yes. We record the locations we have sealed and the products used.
Can you seal over the old sealant?
No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Do you certify the fire stopping?
We don’t certify fire stopping or quote ratings. Our part is installing the specified product to its tested details and list the locations and products for you.
Is there any odour?
That depends on the sealant. Some products have a noticeable smell, others very little.
Is standard sealant good enough for a fire gap?
No. Where a fire-rated seal is needed, it has to be a product tested for that use fitted to the maker’s details.
Do you take out the old sealant first?
Yes, every time. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
Can I do it myself?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Workplaces and buildings in Ham
Ham has hotels and guest accommodation in and around it. For hotels, a room-by-room programme keeps most rooms in use while the work goes on. Commercial buildings in London often have strict access rules and limited loading, so out-of-hours working can be arranged where needed.
Ham is in London, so parking needs planning: let us know about parking bays, permits or a driveway. For landlords with property near Teddington station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. Schools such as Meadlands Primary School are buildings too, and fire-stopping around service openings should be restored whenever new services go in.

How the visit works
You don’t need to clear the whole room or building before we come, only the area right around the joints. We protect the rest, and the work takes from a few hours to a few days, depending on the number of gaps and the access for a typical job. In a London area like Ham, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we’re working on and whether there’s a lift.
- We start with the survey or action list, checking the size and surfaces of every gap.
- 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.
- Fire-rated or intumescent sealant is applied to the right depth and tooled.
- We record the locations and products used for your records.
How to prepare
- Mention any parking rules near the property
- Clear the area around the work
- Mention any tricky access

Advice
Landlord and commercial work in Ham
We work for landlords and letting agents as well as householders. Sealant work between tenants is a simple way to keep a property in good order.
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
What happens if it’s left?
Fire-rated sealants are less forgiving than ordinary ones. How it’s installed changes how it performs, and we work to the product details every time. In a flat in Ham, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
Instead of a standard rate, 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.

How to look after the new joints
A little care helps the new joints last. We recommend:
- Tell trades working in the building that fire seals must be put back
- File the fire-stopping record where your assessor can find it
- Report cracked or damaged seals as soon as you notice them
- Check risers, ceiling voids and cupboards during building checks
Look at the sealed gaps as part of your routine walk-rounds. Look for cracks, gaps or sealant that has been cut or pulled out and get them seen to.
A gap left open in a fire-resisting wall or floor lets smoke spread in ways the building wasn’t designed for. Closing it is normally a straightforward job.
