Hillstreet Fire Rated Sealant
We cover Hillstreet for intumescent and fire-rated sealant around gaps, frames and service penetrations. Old sealant removed completely, joints prepared properly.
- Seals cut through by electricians, plumbers or data installers
- Holes left by a change of layout
- Joints picked up in a fire-stopping survey
Leave it or put it right?
If an assessor has flagged gaps, it makes sense to close them before the next review. Getting them done and written up gives you evidence that the item was dealt with. Older cottages and farmhouses around Hillstreet can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
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. You will get one clear quote for the whole job.

Fire rated sealant in Hillstreet, done properly
Filling a fire-stopping gap with standard silicone or caulk does not make it fire-rated. Anything unsuitable comes out first and reseal with a fire-rated product tested for that kind of gap. We work on linear gaps, service penetrations and flats & HMOs, and people most often call us about open gaps behind door architraves and sealant items on a fire risk assessment action list.
For holiday lets, converted business premises or a community building near Hillstreet, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.
All our work is covered by our 12-month guarantee, wherever you are in Hampshire.

How to look after the new joints
Joint life depends on how it’s used and looked after. We suggest:
- Never patch a fire seal with standard sealant
- Include fire stopping when you schedule refits
- Look in service cupboards and ceiling voids from time to time
- Tell trades working in the building that fire seals must be put back
Follow the cure time we give you before decorating over the sealant. Some fire-rated sealants can be painted and some can’t.
If a fire risk assessment has flagged a gap, don’t leave it for the next one. Get it sealed and recorded so you can show it was dealt with.

DIY versus a professional finish
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
The process
When we arrive, we start by going over the job with you, so you know exactly what we are doing. Surfaces next to the work are protected before any work begins. Most jobs take anything from a few hours to several days, depending on how many gaps there are. For a village or hamlet like Hillstreet, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- First we work through your list or survey, measuring each gap and checking what it’s formed in.
- Old or unsuitable sealant is cut out and the gap cleaned.
- We put in whatever backing or fill the product detail specifies.
- Fire-rated or intumescent sealant is applied to the right depth and tooled.
- Finally, we list where we worked and what we used, for your records.
Preparing for the visit
- Keep pets and children clear of the area while we work
- Mention any parking rules near the property
- Mention any tricky access

Advice
What we’re called out for in Hillstreet
Buildings are refitted and reconfigured over the years. A house turned into flats or an HMO, or an office split into smaller units, brings new walls, new service routes and new gaps.
Any of these means the joints need attention:
- Unsealed gaps where pipes and cables go through a wall
- Ordinary sealant used where a fire-rated product was needed
- Open joints along the top of partitions
- Unsealed gaps around fire door frames
If you look after a church, hall or community building such as St Anne's, service openings in its walls need the right fire-rated sealant, as in any building.
What your quote should include
- Is VAT in the price?
- Whether all the old sealant comes out first
- Who does the work, and how experienced they are
- What happens if they find a problem under the old sealant
What fire rated sealant looks like in Hillstreet
For seaside hotels, guest houses and holiday lets around Hillstreet, busy months put washrooms and kitchens under pressure, so it’s worth checking the sealant before the busiest weeks. 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 Calmore Junior School, fire-stopping around service openings should be restored whenever new services go in. If you let a flat or house near Totton station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

Common questions in Hillstreet

A typical job takes a few hours for a handful of gaps, and longer for a whole building. Your quote will say how long we expect yours to take.
Where are you based?
We’re a Crawley-based firm. Our area covers South East England, London and Scotland.
Is there any odour?
Some sealants have a smell while they cure, but it fades. Ventilation helps.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status and we are fully insured too.
When it is not the sealant
Some problems need a builder, plumber or other trade rather than us:
- Doors that aren’t fire doors in the first place
- A wall that is not a fire-resisting element to begin with
- Big openings where sealant alone is not the tested solution
Not sure which it is? You can phone 0345 464 0079 or email us and we will tell you honestly before booking.
