Workplaces and buildings in Little Wymondley
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 buildings such as Church of St Mary the Virgin, older buildings that have had new heating or wiring often have service gaps worth checking. Managing a site like Wymondley Junior Mixed and Infant School? Then gaps opened by contractors for new cabling are a common finding in schools and offices.

Fire rated sealant for homes and businesses in Little Wymondley
Until it’s heated, intumescent sealant behaves like an ordinary sealant; in a fire it expands into the joint. Which product suits a gap depends on its width, the materials either side and what runs through it, so we follow the tested detail for each one. If you are dealing with old fire sealant that has split or come away and door frames with gaps between frame and wall, we can help, whatever the surface.
For a small place like Little Wymondley, the journey and timings are agreed in advance, so the job can fit around bookings, guests or opening times where possible.
Whatever the size of the job, it’s backed by our 12-month guarantee in Little Wymondley and across Hertfordshire.

What affects the cost of fire rated sealant
Some jobs are bigger than they look, and some smaller. The main factors:
- Whether the work is at height
- The product the joint needs
- When we can work, for business premises
- How much old sealant there is and how hard it is to remove
Doing several joints on one visit usually makes better use of the time than several visits. You’ll get one clear quote for the whole job.
Helping us quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- Photos by email, if that’s easy
- How many joints, rooms or windows are involved
- Whether it’s a home or a business
- The address or postcode of the job
Every job is quoted individually, so the first step is telling us about yours. Simply ring 0345 464 0079 or send us an email and describe the job, and photos are welcome.
Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- Flag any open gap you spot round a pipe or cable
- Ask every contractor to reseal any fire stopping they disturb
- Keep the record of products and locations with your fire safety documents
- Never patch a fire seal with standard sealant
Avoid covering a sealed gap with anything that isn’t part of the tested detail. Repairs should use a matching fire-rated product. Ask us if you’re not sure which product was used.
A flagged gap shouldn’t wait for the next assessment. Have it sealed, then keep the record so the item can be closed.

- Before starting, we go through the specification or action list with you.
- We measure every gap and note what it’s in and what passes through.

- Mention if the joints have been sealed before

Advice
DIY sealant or a professional job?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Leave it or put it right?
An open gap in a fire-resisting wall is a route for smoke and fire. Sealing it properly restores what the wall was there to do, and the work involved is often modest. Older cottages and farmhouses around Little Wymondley can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

What we’re called out for in Little Wymondley
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.
These are the problems we are asked about most:
- Seals cut through by electricians, plumbers or data installers
- Fire seals that have cracked with movement
- Sealant items on a fire risk assessment action list
- Linear gaps at the head of walls
Rented homes near Hitchin station change hands often, and fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.
Before you book anyone
- Whether all the old sealant comes out first
- How the joint is cleaned and prepared
- Whether the sealant suits the joint
- The length of the guarantee
What the job involves on each surface
Masonry and concrete
Holes through concrete and block are rarely neat. We check the gap size around the service to make sure it suits the product.
Door frames
Frame gaps are normally hidden behind the architrave. We seal any open gap to the product’s tested details so the architrave can be refitted.
