Fire rated sealant around Donnington
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 work to the specification you are given, installing the product to its tested details. Donnington has hotels and guest accommodation in and around it. For hotels, a room-by-room programme keeps most rooms in use while the work goes on.
For landlords with property near Oxford station, any gap left by new services in shared walls should be closed with a fire-rated product. If you look after a building such as Larkrise Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices.

Fire rated sealant in Donnington
We often work from an action list drawn up by a fire risk assessor for buildings in Donnington. If you share the list, we can quote for the gaps that need fire-rated sealant. We’re often asked to deal with joints picked up in a fire-stopping survey and open gaps behind door architraves, on pipe & cable gaps, service penetrations and flats & HMOs.
For a pub, café, guest house or shop in or near Donnington, the washrooms and kitchen need the same attention as a big site, and fire-rated sealant around service openings should be restored after new pipes or cables go through.
All our work is covered by a one-year guarantee.

What we’re called out for in Donnington
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.
The most common problems we see are:
- Holes left by a change of layout
- Gaps flagged on a fire risk assessment
- Fire stopping disturbed by later work
- Unsealed gaps around fire door frames
For buildings such as St Alban the Martyr, service openings in its walls need the right fire-rated sealant, as in any building.

Questions from Donnington
Do you cover smaller places like Donnington?
Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Do you take on hotel work around Donnington?
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.
Do I need to be at home?
It depends on the job. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
I’m a tenant. Can you help?
Yes. Ask your landlord first, and we can send them the quote if that helps.
Can you seal over the old sealant?
No. Fresh sealant doesn’t stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Is standard sealant good enough for a fire gap?
No. Ordinary silicone, caulk or foam isn’t tested as fire stopping. If it’s been used, we remove it and use the right product.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
What do you need from me for a quote?
A short description and the location, plus photos if you have them. If we need more, we’ll ask.
Can I do it myself?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
What we do, step by step
A visit follows a simple pattern: we look at the joints together, protect the area around them, do the work and tidy away. Most jobs take anything from a few hours to several days, depending on how many gaps there are. Parking around Donnington is normally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- 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.
- Any non-fire-rated filler is removed.
- The specified fire-rated sealant goes in over any backing its detail requires.
- We hand over a list of locations and products.
Getting ready for the visit
- Move anything stored near the joints
- Let us know about stairs, lifts or work at height
- Let us know if you’ve seen damp or leaks

Advice
Landlords, agents and businesses in Donnington
In hotels, rooms out of use cost money, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
Leave it or put it right?
Items left open on a fire risk assessment tend to come back at the next review. Having them sealed and recorded now means you can show the action was taken. Homes in smaller places like Donnington can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you are not sure whether it needs doing, phone 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.

Surface by surface
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’ll flag it.
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.
Looking after it afterwards
So the new joints stay in good condition:
- Do not paint over fire sealant until it has cured
- Make resealing part of every contractor’s brief
- Check risers, ceiling voids and cupboards during building checks
- Flag any open gap you spot round a pipe or cable
Any fire seal that’s cut or drilled needs resealing to its tested detail. New services through a sealed wall should include fire stopping in the plan.
When you plan work that goes through walls or ceilings, plan the fire stopping too. Catching it then saves a separate visit later.
