Work for landlords, hotels and businesses
Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.

Fire rated sealant in Nash
Until it’s heated, intumescent sealant behaves like an ordinary sealant; then it swells to help close the gap. The right product depends on the gap size, the substrate and what passes through. If you have joints picked up in a fire-stopping survey and gaps around pipes and cables through fire-resisting walls, we can put it right, on linear gaps, pipe & cable gaps and plasterboard & masonry alike.
London’s offices, shops, hotels, student accommodation and blocks of flats all have joints to look after, whether that is washroom resealing or fire-rated sealant around service openings. Where a building in Nash needs to stay open, work can be planned outside normal hours.
Whatever the size of the job, you get the same 12-month guarantee.

How it works
You don’t need to clear the whole room or building, just the space around the work. We protect the rest, and the work takes from a few hours to a few days, depending on the number of gaps and the access in most cases. In a London area like Nash, the main things to plan are parking and access: let us know about parking, the floor we will be working on and any lift or shared entrance.
- We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
- 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.
- Every location is recorded with the product used.
Preparing for the visit
- Let us know about parking restrictions
- For indoor joints, keep the area dry beforehand if you can
- Mention if the joints have been sealed before

Advice
What we’re called out for in Nash
A lot of fire stopping is out of sight: above ceilings, inside risers and behind panels. Out of view, damage sits unnoticed until someone inspects.
Common reasons people contact us are:
- Damaged fire sealant left by other trades
- Gaps left after a refit or conversion
- Sealant items on a fire risk assessment action list
- Unsealed gaps around fire door frames
Letting a property close to Hayes (Kent) station? Then fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.
Before booking anyone
- Are they insured?
- How the surfaces are prepared before sealing
- Which sealant they’ll use, and why
- The length of the guarantee
Surface by surface
Linear gaps
Long, narrow gaps appear where walls meet slabs and ceilings. They’re sealed with a fire-rated sealant over backing where the detail calls for it.
Service penetrations
Service penetrations are where new gaps often appear. We clean out what’s there and reseal to the right depth over any backing the detail calls for.
Workplaces and buildings in Nash
Many London buildings have tight access and loading restrictions, so out-of-hours working can be arranged where needed. Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, and gaps around services are often picked up there. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
For buildings such as Keston Parish Church, older buildings that have had new heating or wiring often have service gaps worth checking. Nash is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

Nash questions
Can you help a landlord with a rental near Hayes (Kent) station?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear quote.
Can you do fire rated sealant in Nash?

Is the work guaranteed?
Yes. Every job comes with our 12-month guarantee.
Are you an approved applicator?
Yes. We are approved under the ARBOMaster scheme.
Do you carry out fire risk assessments?
No. That is for a fire risk assessor, designer or building control. Our job is applying the sealant to their specification.
Do you do fire sealant around door frames?
Yes. We seal the gap between the frame and the wall with a suitable fire-rated product following the tested details. The door, its seals and closer are for a door specialist.
Do you work in flats, HMOs and commercial buildings?
Yes. Flats, HMOs, offices, schools and other occupied buildings are all part of our work. The order of work and access are planned with you.
Is it OK to seal over old sealant?
No, because it fails. The old sealant always comes out first, so the new joint bonds to clean surfaces.
What sealant work cannot fix
New sealant cannot fix everything, and we’d rather say so up front. Sealant won’t put right:
- Walls or floors that weren’t built to resist fire
- Assessing a building’s fire safety
- Problems with the door itself rather than the gap around the frame
If you’re not sure, just ring 0345 464 0079 or send us an email and we will give you a straight answer.
What we seal
- Plasterboard & masonry
- Service penetrations
- Flats & HMOs
- Linear gaps
- Pipe & cable gaps
- Door frames

Keeping the joints in good condition
Joint life depends on how it’s used and looked after. We suggest:
- File the fire-stopping record where your assessor can find it
- Include fire stopping when you schedule refits
- Keep photos of seals that will be hidden
- Check risers, ceiling voids and cupboards during building checks
Follow the cure time we give you before decorating over the sealant. Some fire-rated sealants can be painted and some cannot.
Small gaps around services are simple to deal with while there are only a few. Over time, more work adds more holes.
