Keep an eye out for any of the following:
- New service routes left unsealed after building work
- Seals cut through by electricians, plumbers or data installers
- Gaps flagged on a fire risk assessment

Fire rated sealant for homes and businesses in Rooks Nest
We do not assess buildings or decide what fire stopping is needed; your assessor, designer or building control sets that out. Our part is applying the specified sealant carefully, to the right depth and with the right backing. We’re often asked to deal with linear gaps at the head of walls and joints picked up in a fire-stopping survey, across plasterboard & masonry, service penetrations and pipe & cable gaps.
For a small place like Rooks Nest, the journey and timings are agreed in advance, so it can be fitted around guests, customers or events where possible.
Your job is guaranteed for a year, as with all our work.

Commercial buildings in Rooks Nest
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 work to the specification you’re given, installing the product to its tested details. Stevenage, which Rooks Nest is part of, is one of England’s post-war new towns. Like the other new towns, Stevenage was planned with its own areas for industry and business, so there are offices, units and workplaces not far from home. Each has washrooms, kitchens and fire-rated joints to keep in order.
Schools such as Trotts Hill Primary and Nursery School are buildings too, and gaps opened by contractors for new cabling are a common finding in schools and offices. If you look after a church, hall or community building such as Church of Saint Nicholas, older buildings that have had new heating or wiring often have service gaps worth checking.

Rooks Nest questions
Will you come out to Rooks Nest?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Is Rooks Nest in your area for fire rated sealant?
Yes. We work across London and the South East, and Rooks Nest is part of that. You can phone 0345 464 0079 or send us an email and tell us what needs doing, and we will give you a clear quote.
Can you tell me how many minutes the seal will last?
We don’t issue ratings or certificates ourselves. What’s required is set by your assessor or designer, and the product’s tested details show what it achieves.
Can you tell me which gaps need fire stopping?
No. We follow the requirements from your assessor, designer or building control and install to the manufacturer’s details.
Where do you work from?
We work from Crawley. Our applicators cover Rooks Nest.
Is the work guaranteed?
Yes. There’s a 12-month guarantee on every job, wherever you are.
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.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we’ll tell you what we’re using.
What affects the cost of fire rated sealant
Some jobs are bigger than they look, and some smaller. The main factors:
- How much there is to do
- How many areas need sealing
- The product the joint needs
- The old material and how stubborn it is
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we will explain the quote if you ask.
Helping us quote
Photos by email are helpful but not essential. Try to tell us:
- Pictures of the joints, sent by email
- Access, such as stairs, a lift or height
- How many joints, rooms or windows are involved
- The type of property
Asking for a quote is easy: tell us what needs doing and where and its rough size. Photos by email help us understand the job, and we will come back to you with a quote.

Why deal with it now?
Items left open on a fire risk assessment tend to come back at the next review. Getting them done and written up gives you evidence that the item was dealt with. Where a wall is exposed, as many are in small places like Rooks Nest, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Doing several joints on one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We will send you a clear quote for the lot.

DIY sealant or a professional job?
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.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
Looking after it afterwards
Looking after new joints is easy, and it makes a real difference:
- Keep general-purpose foam and caulk away from fire-stopping gaps
- Get damaged fire seals looked at promptly
- Ask which product was used before you paint
- Plan fire stopping into any work that goes through walls or floors
File the record of locations and products with your fire safety paperwork. It saves time at the next inspection or assessment.
A flagged gap shouldn’t wait for the next assessment. Get it sealed and recorded so the item can be closed.
What happens on the day
Good joint work is mostly preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes from a few hours to a few days, depending on the number of gaps and the access. In a small place like Rooks Nest, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- Before starting, we go through the specification or action list with you.
- Each gap is measured and its substrate and service noted.
- Any non-fire-rated filler is removed.
- The specified fire-rated sealant goes in over any backing its detail requires.
- We hand over a list of locations and products.
