Fire-rated sealant in Galleywood, Essex

- Door frames with gaps between frame and wall
- Ordinary sealant used where a fire-rated product was needed
Looking after it afterwards
A little care helps the new joints last. We recommend:
- Check risers, ceiling voids and cupboards during building checks
- Report cracked or damaged seals as soon as you notice them
- Make resealing part of every contractor’s brief
- Do not paint over fire sealant until it has cured
Keep the record we give you with the building’s fire safety documents. It saves time at the next inspection or assessment.
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.
How we handle fire rated sealant in Galleywood
We do not assess buildings or decide what fire stopping is needed; that comes from your fire risk assessor, designer or building control. Our part is applying the specified sealant carefully, to the right depth and with the right backing. If you are dealing with open holes round services passing through fire walls and fire stopping disturbed by later work, we can help.
For a pub, café, guest house or shop in or near Galleywood, its washrooms and kitchen need the same sealant care as any big building.
You get a 12-month guarantee, the same in Galleywood as everywhere else we work.

What fire rated sealant looks like in Galleywood
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.
For site and facilities teams at buildings such as St Michael's Church of England Voluntary Aided Junior School, gaps opened by contractors for new cabling are a common finding in schools and offices. For buildings such as Church of St Michael and All Angels, older buildings that have had new heating or wiring often have service gaps worth checking.

What we do, step by step
Good joint work is mostly preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes from a few hours to a few days, depending on the number of gaps and the access. For a job in Galleywood, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- 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.
- Backing or fill is fitted where the product’s tested detail calls for it.
- The sealant goes in to the depth its detail sets, then it’s tooled off.
- We record the locations and products used for your records.
Before we arrive

Common problems we fix in Galleywood
Much fire stopping is hidden: above ceilings, inside risers and behind panels. Out of view, damage sits unnoticed until someone inspects.
These are the problems we’re asked about most:
- Gaps filled with a product that is not fire-rated
- Door frames with gaps between frame and wall
- Gaps flagged on a fire risk assessment
- New service routes left unsealed after building work
If you let a flat or house near Chelmsford station, any gap left by new services in shared walls should be closed with a fire-rated product.
What to look for in a quote

- What the quote includes, VAT included or not
- Who does the work, and how experienced they are
- Is the old sealant removed completely?
Honest limits
Sealant isn’t the answer to every problem, and we’d rather say so up front. It won’t solve:
- Assessing a building’s fire safety
- Problems with the door itself rather than the gap around the frame
- Big openings where sealant alone isn’t the tested solution

What else we do in Galleywood
Can I do it myself?
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.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Different surfaces, different methods
Plasterboard walls
Holes in plasterboard are often cut roughly for services. Gaps that are too big for sealant alone need a different detail and we will flag it.
Linear gaps
Gaps along the top of partitions are easy to miss above a ceiling. We seal them along their full length leaving no stretch unsealed.
