Advice
About our fire rated sealant in Monkswood
Until it’s heated, intumescent sealant behaves like an ordinary sealant; in a fire it expands into the joint. The right product depends on the gap size, the substrate and what passes through, so we follow the tested detail for each one. We work on door frames, service penetrations and plasterboard & masonry, and people most often call us about fire stopping disturbed by later work and open gaps behind door architraves.
In a village or hamlet like Monkswood, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. They all have washrooms, kitchens and service openings that need the right sealant.
Big or small, you get the same one-year guarantee.

Looking after it afterwards
So the new joints stay in good condition:
- Store the list of sealed gaps with your building paperwork
- Ask every contractor to reseal any fire stopping they disturb
- Look in service cupboards and ceiling voids from time to time
- Report cracked or damaged seals as soon as you notice them
Keep the record we give you with the building’s fire safety documents. It helps whoever checks the building next.
An open gap is not only a fire issue: noise, draughts and even pests can come through too. Dealing with them early helps with all of these.

Are you insured?
Yes, we’re fully insured.
When it is not the sealant
In fairness, some problems need a different trade:
- Deciding what fire stopping a building needs
- Large holes that need a different fire-stopping system
- Certifying a building or signing off its fire safety

What we’re called out for in Monkswood
Much fire stopping is hidden: in ceiling voids, service risers and behind boxing. Because nobody sees it, gaps go unnoticed until an assessor or surveyor looks.
People usually contact us when they notice something like this:
- Joints picked up in a fire-stopping survey
- Standard silicone or caulk in a fire-stopping gap
- Door frames with gaps between frame and wall
- Linear gaps at the head of walls
Community buildings like The Parish Church of St John are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building.
What your quote should include
- What the quote includes, VAT included or not
- Whether all the old sealant comes out first
- Whether the sealant suits the joint
- Whether you can choose the colour
Commercial buildings in Monkswood
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.
If you let a flat or house near Welwyn North station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. If you look after a building such as Homerswood Primary and Nursery School, service openings in fire-resisting walls need checking after any refurbishment.

Why act early in Monkswood
A quick fill with any sealant to hand is not fire stopping. Fire-rated products are tested in set gap sizes, depths and substrates, which is why we match the product and the method to each gap. Around Monkswood, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.

Different surfaces, different methods
Service penetrations
New gaps tend to show up where services have been added. We clean out what’s there and reseal to the right depth over any backing the detail calls for.
Linear gaps
A linear joint may need to allow for movement as well as fire. The product and depth are chosen to suit both, following the tested detail.
DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
