Fire rated sealant for homes and businesses in Widley
Ordinary silicone or decorators’ caulk in a fire-stopping gap isn’t a fire-rated seal. We cut out the wrong material and reseal with a fire-rated product tested for that kind of gap. Typical jobs include linear gaps at the head of walls and old fire sealant that has split or come away, across pipe & cable gaps, service penetrations and linear gaps.
For a small place like Widley, the journey and timings are agreed in advance, so it can be fitted around guests, clients or events where possible.
Every job is covered by our one-year guarantee, wherever you are in Hampshire.

Honest limits

- Certifying a building or signing off its fire safety
- Assessing a building’s fire safety
- Openings too large for sealant, which need batts, boards or another system
If you are not sure, just ring 0345 464 0079 or send us an email and we’ll give you a straight answer before booking.

The process
On the day, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before we start. Most jobs take a few hours for a handful of gaps, and longer for a whole building. For a village or hamlet like Widley, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- 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.
- Unsuitable material such as ordinary foam or silicone is cut out and the gap cleaned.
- We fit backing where needed and apply the fire-rated sealant to depth.
- We hand over a list of locations and products for your records.
Before we arrive
- Mention if the joints have been sealed before
- Clear the area around the work
- Tell us about access, such as stairs, a lift or high-level joints

How the job changes by surface
Linear gaps
Linear gaps run along the head of walls, at floor edges and between panels. They’re sealed with a fire-rated sealant over backing where the detail calls for it.
Service penetrations
Different services need different details: metal pipes, cables and plastic pipes are not treated the same. Each one is sealed to the product’s tested detail, and tell you if sealant alone isn’t the right fix.
What fire rated sealant looks like in Widley
If you run a hotel, guest house or holiday let in a coastal place like Widley, heavy use in the busy months is hard on washroom and kitchen sealant, and any building work there should leave fire-rated joints made good. 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, and gaps around services are often picked up there. We work to the specification you are given, installing the product to its tested details.
For site and facilities teams at buildings such as Purbrook Park School, service openings in fire-resisting walls need checking after any refurbishment. Letting a property close to Cosham station? Then fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. For buildings such as Christ Church, older buildings that have had new heating or wiring often have service gaps worth checking.

Why deal with it now?
Squirting in whichever sealant is nearest does not make a fire seal. 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. Where a wall is exposed, as many are in small places like Widley, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.

Questions from Widley
Is Widley within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you help a landlord with a rental near Cosham station?
Yes, we work for letting agents and landlords. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before any work starts.
Can you fill the gap behind a fire door frame?
Yes. Gaps behind architraves are a common job for us. Doors, seals and closers need a door specialist.
Is it OK to seal over old sealant?
No. Fresh sealant does not stick to old sealant, and anything trapped underneath, including mould and water, stays there. It all has to come out first.

Keeping the joints in good condition
Aftercare is simple, and it makes a real difference:
- Keep pictures of seals that will be hidden
- Make resealing part of every contractor’s brief
- Include fire stopping when you schedule refits
- Ask which product was used before you paint
Include fire stopping in your regular building checks. Look for cracks, gaps or sealant that has been cut or pulled out and get them seen to.
Open gaps do not only matter in a fire: they also let noise, draughts and sometimes pests through. Sealing them early helps on every front.
