Common questions in Witney
Do you take on hotel work around Witney?
Yes. Hotel and guest-house work is part of what we do. Work can be planned room by room, and out-of-hours working can be arranged.
Can you help a landlord with a rental near Finstock station?
Yes, landlords and agents are among the people we work for. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we will send you a clear quote.
Can you match the sealant colour?
Usually, yes. Sealants come in white, clear, grey and other colours for many products, and we’ll agree it with you first.
Do you certify the fire stopping?
That isn’t something we state or certify. Your specification sets the requirement, and we fit a product whose tested details meet it with a record of each location.
Is it OK to seal over old sealant?
No. We remove every bit of old sealant first, so the new sealant bonds properly.
Will you leave a mess?
We keep the work tidy. We protect what’s around the joints, and we clear up when we are done.
Do you work in Witney?
Yes. From our base in Crawley, we cover South East England, London and all of Scotland.
Do you hold any approvals?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Fire rated sealant in Witney
Deciding which gaps need fire stopping is not our role; that comes from your fire risk assessor, designer or building control. What we do is apply the right product to that specification, properly and neatly. Common call-outs are for door frames with gaps between frame and wall and sealant items on a fire risk assessment action list, on door frames, plasterboard & masonry and service penetrations.
Washrooms in busy buildings wear their sealant out faster than a bathroom at home, and fire-rated joints need restoring whenever new services are run through a wall. In Witney, timings are planned around the building.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

Can I do it myself?
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What we cannot put right
Sealant isn’t the answer to every problem, and we will tell you before any work starts. Sealant will not put right:
- Walls or floors that weren’t built to resist fire
- Deciding what fire stopping a building needs
- Large holes that need a different fire-stopping system
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we will tell you honestly.

- Service penetrations
- Pipe & cable gaps
- Flats & HMOs
- Plasterboard & masonry

The process
Most of a good job is in the preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it normally takes from a few hours to a few days, depending on the number of gaps and the access. For a job in Witney, we need access to where the work is and somewhere nearby to park. If the job is outside, mention gates, side access and anything above ground floor.
- We go through the gaps on your list or survey and check each one’s size and substrate.
- Old or unsuitable sealant is cut out and the gap cleaned.
- We put in whatever backing or fill the product detail specifies.
- The sealant goes in to the depth its detail sets, then it’s tooled off.
- Finally, we list where we worked and what we used, for your records.
Before we arrive
- Keep pets and children clear of the area while we work
- Let us know if you’ve seen damp or leaks
- Let us know about parking restrictions

Looking after it afterwards
After the cure time, these simple habits help:
- Keep the record of products and locations with your fire safety documents
- Flag any open gap you spot round a pipe or cable
- Include hidden areas like risers in routine checks
- Check whether a sealant can be painted before decorating over it
File the record of locations and products with your fire safety paperwork. It saves time at the next inspection or assessment.
Small gaps around services are simple to deal with while there are only a few. Over time, more work adds more holes and the list grows.
Different surfaces, different methods
Door frames
We deal with the gap around the frame, not the door. The door leaf, its seals and closer need a door specialist and we’ll mention anything we notice.
Plasterboard walls
Service holes in plasterboard are often rough and oversized. Gaps that are too big for sealant alone need a different detail and we will flag it.
What happens if it’s left?
For some gaps, sealant isn’t the right answer and another system is needed. Large holes, cable bundles and plastic pipes can call for batts, collars or wraps. If a gap isn’t suitable for sealant, we will tell you. In Witney, as anywhere, most leaks start as a small gap in a joint, and they’re far easier to fix early.
Doing several joints on one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. We’ll send you a clear quote for the lot.

What fire rated sealant looks like in Witney
Witney has hotels and guest accommodation in and around it. Hotel work can be planned room by room, with out-of-hours working 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, 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 Witney Congregational Church, older buildings that have had new heating or wiring often have service gaps worth checking. For site and facilities teams at buildings such as Tower Hill Community Primary School, fire-stopping around service openings should be restored whenever new services go in. Rented homes near Finstock station change hands often, and any gap left by new services in shared walls should be closed with a fire-rated product.
