- Door frames with gaps between frame and wall
- Open holes round services passing through fire walls
- Fire seals that have cracked with movement
Looking after it afterwards
Aftercare is simple:
- Get damaged fire seals looked at promptly
- Make resealing part of every contractor’s brief
- Look in service cupboards and ceiling voids from time to time
- Keep the record of products and locations with your fire safety documents
Follow the cure time we give you before decorating over the sealant. Some fire-rated sealants can be painted and some cannot.
It’s easiest to seal gaps while they’re few and easy to reach. Over time, more work adds more holes.
Fire rated sealant in Carpenders Park, done properly
We often work from an action list drawn up by a fire risk assessor. Send us the list or the survey and we will quote for the fire-rated sealant work on it. If you have unsealed gaps where pipes and cables go through a wall and linear gaps at the head of walls, we can put it right, on door frames, linear gaps and pipe & cable gaps 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 Carpenders Park, that can mean fire-rated sealant around service openings as well as resealing in shared washrooms and kitchens.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Honest limits
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Problems with the door itself rather than the gap around the frame
- Assessing a building’s fire safety
- Big openings where sealant alone is not the tested solution
If you’re not sure, just ring 0345 464 0079 or drop us an email and we’ll give you a straight answer.

What else we do in Carpenders Park
Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
What a professional job adds is preparation and the right 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.
Fire rated sealant in Carpenders Park: local notes
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 work to the specification you are given, installing the product to its tested details.
Carpenders Park is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. For buildings such as Oxhey Chapel, service openings in its walls need the right fire-rated sealant, as in any building.

How we quote for fire rated sealant
Jobs vary more than people expect. What affects the quote:
- Whether the work is at height
- How much old sealant there is and how hard it is to remove
- How many rooms, windows or areas are involved
- How much there is to do
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re unsure, call 0345 464 0079 or email us for an honest opinion and a quote.
Asking for a quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- Access, such as stairs, a lift or height
- How many joints, rooms or windows are involved
- The address or postcode of the job
- If it’s domestic, commercial or a hotel
For a quote, call 0345 464 0079 or send us an email with the location and a short description of the problem. We’ll give you a clear price before any work starts.
What we do, step by step
Most of a good job is in the preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it generally takes anything from a few hours to several days, depending on how many gaps there are. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.
- Before starting, we go through the specification or action list with you.
- Each gap is measured and its substrate and service noted.
- Unsuitable material such as ordinary foam or silicone is cut out and the faces cleaned.
- We fit backing where needed and apply the fire-rated sealant to depth.
- Every location is recorded with the product used.
How to prepare
- Try not to wet indoor joints just before the visit
- Plan for the work area to be out of bounds to pets and children
- Let us know about stairs, lifts or work at height

Why act early in Carpenders Park
Items left open on a fire risk assessment tend to come back at the next review. Having them sealed and recorded now means you can show the action was taken. 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.
The cost depends on the amount of work, how hard the old material is to remove and access to the work. We give a clear quote before any work starts.

Common problems we fix in Carpenders Park
If the sealant is too shallow, has the wrong backing or sits on a dusty surface, it isn’t installed as tested. Rushed fire stopping is common.
Look out for these signs:
- Open gaps behind door architraves
- Cracked or shrunken fire-rated sealant
- Gaps around pipes and cables through fire-resisting walls
- Gaps filled with a product that is not fire-rated
Schools such as St Meryl School are buildings too, and gaps opened by contractors for new cabling are a common finding in schools and offices.
Questions to ask before booking
- Whether the sealant suits the joint
- How long to leave it before use
- What insurance they hold
- What happens if they find a problem under the old sealant
