- Damaged fire sealant left by other trades
- Unsealed gaps around fire door frames
- Gaps around pipes and cables through fire-resisting walls
What we do, step by step
We work through the job in order: protect, prepare, seal, tidy. Typically it takes anything from a few hours to several days, depending on how many gaps there are, and the area is left clean. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Walthamstow. It helps if you can point us to a visitor permit or a bay close to the door.
- We go through the gaps on your list or survey and check each one’s size and substrate.
- We remove any old or unsuitable filler and clean the gap.
- Where the tested detail needs backing or fill, we fit it.
- The sealant goes in to the depth its detail sets, then it’s tooled off.
- Locations and products are noted so you have them on file.
Before we arrive
- Tell us about any previous sealing or DIY attempts
- For business premises, tell us about site rules or sign-in

About our fire rated sealant in Walthamstow
Bigger jobs can be worked through in stages, flat by flat or floor by floor, with each location and product recorded. It gives you a list to keep with the building’s fire safety documents. We work on flats & HMOs, plasterboard & masonry and door frames, and common reasons people get in touch are old fire sealant that has split or come away and standard silicone or caulk in a fire-stopping gap.
London blocks of flats carry pipes and cables through walls and floors in their common parts and service risers. For managing agents and building owners in Walthamstow, that can mean fire-rated sealant around service openings as well as resealing in shared washrooms and kitchens.
You are covered for a year from the day we finish. If there’s a problem with it, please ring 0345 464 0079 or drop us an email.

Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. Our tips:
- Get damaged fire seals looked at promptly
- Allow for resealing whenever new services are run
- Check whether a sealant can be painted before decorating over it
- Never patch a fire seal with standard sealant
Tell other trades that the gaps have been sealed, 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: they also let noise, draughts and sometimes pests through. Dealing with them early helps with all of these.

What affects the quote in Walthamstow
Some jobs are bigger than they look, and some smaller. What affects the quote:
- When we can work, for business premises
- Whether old sealant or filler has to be cut out
- The type of sealant required
- Whether the work is at height
The cost reflects the work involved, not guesswork. That’s why we ask about the job first.
What we need to know
Photos by email are helpful but not essential. Please mention:
- Any previous sealing or DIY work
- What’s wrong with the joints now
- Where the property is
- Whether it’s a home or a business
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is. When it suits you, phone 0345 464 0079 or send us an email.
Why act early in Walthamstow
An unsealed gap lets smoke and fire get round a wall that was built to hold them back. A proper seal lets the wall do its job again, and the work involved is often modest. 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 for homes in Walthamstow.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.

Landlord and commercial work in Walthamstow
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
If you manage several properties in or around Walthamstow, jobs at different addresses can go on one quote. Just tell us the addresses and what each one needs.
Can I do it myself?
If you do try it yourself, take your time over the 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.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
When to call us in Walthamstow
Sometimes the wrong product was used from the start: general-purpose foam, everyday silicone or caulk in a place that needed a tested fire seal. It looks sealed, but it is not fire-rated.
Keep an eye out for any of the following:
- Fire stopping disturbed by later work
- New service routes left unsealed after building work
- Ordinary sealant used where a fire-rated product was needed
- Unsealed gaps where pipes and cables go through a wall
Rented homes near Walthamstow Central station change hands often, and any gap left by new services in shared walls should be closed with a fire-rated product.

What fire rated sealant looks like in Walthamstow
Commercial buildings in London often have strict access rules and limited loading, so out-of-hours working can be arranged where needed. 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, 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.
Walthamstow is in London, so parking needs planning: let us know about parking bays, permits or a driveway. Community buildings like Church of St Michael and All Angels are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building.

Your questions about fire rated sealant in Walthamstow

Is parking an issue for fire rated sealant in Walthamstow?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. The visit is then planned around what’s available.
What do you put in the joint?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we will explain our choice.
Do you certify the fire stopping?
We do not give ratings or certificates for our work. The requirement comes from your assessor, designer or building control, and we apply a product tested for it.
Is there any odour?
There can be a smell while the sealant cures, which fades as it sets. Opening a window helps.
Is intumescent sealant the same as fire-rated sealant?
An intumescent material expands when it’s heated. Intumescent sealants are a type of fire-rated sealant and which one is used depends on the job.
Can you work in occupied buildings?
Yes. We work in flats, HMOs, schools, offices and other commercial buildings, including occupied ones. We agree access and the order of work with you first.
Will you assess my building’s fire safety?
No. We follow the requirements from your assessor, designer or building control.
