Fire rated sealant in Hammersmith, done properly
Where services or frames pass through a fire-resisting wall or floor, the gap around them needs a fire-rated seal. Each gap is sealed to the product maker’s tested detail for its size and substrate, and we can record what went where. If you have holes left by a change of layout and gaps flagged on a fire risk assessment, we can put it right, on pipe & cable gaps, door frames and plasterboard & masonry alike.
London blocks of flats carry pipes and cables through walls and floors in their common parts and service risers. In Hammersmith, building managers may need both fire-rated sealant around those openings and new sealant in shared washrooms.
Each job carries a 12-month guarantee, whatever its size.

How the visit works
We bring everything the job needs with us. Once we’ve agreed what’s being done, the area is protected and the work begins. Most jobs take from a few hours to a few days, depending on the number of gaps and the access. In Hammersmith, as in most of London, parking needs a little planning. It helps if you can point us to a visitor permit or a bay close to the door.
- First we work through your list or survey, measuring each gap and checking what it’s formed in.
- We remove any old or unsuitable filler and clean the gap.
- Where the tested detail needs backing or fill, we fit it.
- We apply the fire-rated or intumescent sealant to the specified depth and tool it.
- Locations and products are noted so you have them on file.
Preparing for the visit
- Mention any parking rules near the property
- Mention any tricky access
- Let us know about earlier repairs to the joints

Advice
Common questions in Hammersmith
Do you work for landlords with property near Kensington Olympia station?
Yes. We work for landlords and letting agents as well as householders. Just call 0345 464 0079 or email us with the address and what needs doing, and we will send you a clear quote.
Do you work in hotels near Hammersmith?
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.
How long will you be here?
That depends on the amount of work, but most jobs take from a few hours to a few days, depending on the number of gaps and the access. We will give you a better idea when we quote.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Does someone need to be in?
That depends on where the joints are. For work indoors, someone needs to let us in.
Do you certify the fire stopping?
Ratings and certification sit with the product’s test evidence and whoever specified the work. Our part is installing the specified product to its tested details and giving you a record of where it went.
Can you seal over the old sealant?
No, it won’t last. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Can you match the sealant colour?
In most cases you can choose. We will explain which colours are available.
What fire rated sealant looks like in Hammersmith
Commercial buildings in London often have strict access rules and limited loading, and out-of-hours working is possible to arrange. There are hotels and other places to stay in and around Hammersmith. Hotel work can be planned room by room, with out-of-hours working where needed.
If you look after a building such as Corona Theatre School, fire-stopping around service openings should be restored whenever new services go in. For buildings such as Church of the Holy Innocents, service openings in its walls need the right fire-rated sealant, as in any building.

Signs you need fire rated sealant in Hammersmith
If the sealant is too shallow, has the wrong backing or sits on a dusty surface, it isn’t installed as tested. We see plenty of fire stopping that was hurried, especially where it was squeezed in at the end of a project.
Keep an eye out for any of the following:
- New service routes left unsealed after building work
- Joints picked up in a fire-stopping survey
- Fire seals that have cracked with movement
- Damaged fire sealant left by other trades
Rented homes near Kensington Olympia station change hands often, and fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

When it is not the sealant
We’d rather tell you now than do work that will not last, so here’s what sealant can’t put right:
- A wall that is not a fire-resisting element to begin with
- Problems with the door itself rather than the gap around the frame
- Large holes that need a different fire-stopping system
If you’re not sure, just ring 0345 464 0079 or send us an email and we’ll give you a straight answer.

Why act early in Hammersmith
Waiting for the next refit can leave a gap open for years. On its own, sealing it now is a small job. In a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are unsure, call 0345 464 0079 or send us an email for an honest opinion and a quote.

Keeping the joints in good condition
Looking after new joints is easy, and it makes a real difference:
- Allow for resealing whenever new services are run
- Check risers, ceiling voids and cupboards during building checks
- Take pictures of fire stopping before ceilings or boxing go back
- Flag any open gap you spot round a pipe or cable
Let contractors know where fire stopping has been done, and ask them to reseal anything they cut through. A lot of damaged fire stopping comes from later work.
An open gap is not only a fire issue: noise, draughts and even pests can come through too. Dealing with them early helps with all of these.
DIY sealant or a professional job?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
