How we handle fire rated sealant in Preston
We can work through a building room by room or floor by floor. It gives you a list to keep with the building’s fire safety documents. Typical jobs include ordinary sealant used where a fire-rated product was needed and gaps where walls meet ceilings or slabs, across linear gaps, plasterboard & masonry and door frames.
In London, a commercial job often starts with access: loading bays, building rules and lifts. Timings and access are agreed with the building before work starts in Preston, and room-by-room programmes can be planned where needed.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

Commercial buildings in Preston
Commercial buildings in London often have strict access rules and limited loading, and out-of-hours working is possible to arrange. 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 work to the specification you’re given, installing the product to its tested details.
For site and facilities teams at buildings such as Preston Park Primary School, service openings in fire-resisting walls need checking after any refurbishment. If you look after a church, hall or community building such as Church of the Ascension, service openings in its walls need the right fire-rated sealant, as in any building.

When something else is needed
In fairness, there are a few things sealant won’t fix:
- Certifying a building or signing off its fire safety
- Fire doors that need new seals, closers or hardware
- Big openings where sealant alone is not the tested solution
If in doubt, call 0345 464 0079 or drop us an email and we’ll say what we think.

Why it’s worth doing now in Preston
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. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Preston, the repair is bigger than a sealant job.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please ring 0345 464 0079 or send us an email.

DIY versus a professional finish
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
How we quote for fire rated sealant
Jobs vary more than people expect. What affects the quote:
- Access and height
- How many rooms, windows or areas are involved
- When we can work, for business premises
- The type of sealant required
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part.
What we need to know
Photos help, but a description is a good start. Please mention:
- If someone has resealed it before
- What’s wrong with the joints now
- A few pictures by email, if you can
- How many joints, rooms or windows are involved
Asking for a quote is easy: let us know the job and the location. A few photos by email make the job easier to understand, and we’ll come back to you with a quote.
What we are called out for in Preston
Over time, buildings change layout and use. Conversions to flats and HMOs, and office refits, create new walls and new routes for services, with gaps to match.
Common reasons people contact us include:
- Seals cut through by electricians, plumbers or data installers
- Gaps around pipes and cables through fire-resisting walls
- Old fire sealant that has split or come away
- Standard silicone or caulk in a fire-stopping gap
As a London address, Preston can be tricky for parking: let us know about parking bays, permits or a driveway.
What your quote should include
- Is VAT in the price?
- What insurance they hold
- Is the old sealant removed completely?
- What happens if the job turns out different
Looking after it afterwards
To keep the joints looking good and working properly:
- Flag any open gap you spot round a pipe or cable
- Check risers, ceiling voids and cupboards during building checks
- Never patch a fire seal with standard sealant
- Plan fire stopping into any work that goes through walls or floors
Keep the record we give you with the building’s fire safety documents. It helps whoever checks the building next.
A flagged gap shouldn’t wait for the next assessment. Get it sealed and recorded so the item can be closed.
Questions from Preston
Do you take on hotel work around Preston?
Yes, hotels and guest houses are among the places we work. A room-by-room programme keeps most rooms in use while the work goes on.
Is parking an issue for fire rated sealant in Preston?
Parking in Preston, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
What does fire rated sealant cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote.
Can ordinary silicone be used in a fire-stopping gap?
No. A gap that needs fire stopping needs a tested fire-rated product, installed to its details.
Do you come to Preston?
We do. Our applicators work in Preston.
Are you insured?
Yes. Full insurance covers our work.
Can you do several jobs on one visit?
Of course. Doing several areas at once is generally more efficient.
Can I choose the sealant colour?
In most cases you can choose. We’ll tell you which colours the right product comes in and agree one before work begins.
What happens on the day
Most of a good job is in the preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for a handful of gaps, and longer for a whole building. In Preston, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.
- First we work through your list or survey, measuring each gap and checking what it’s formed in.
- Anything that is not fit for the job comes out, and the gap is cleaned.
- We put in whatever backing or fill the product detail specifies.
- We apply the fire-rated or intumescent sealant to the specified depth and tool it.
- Locations and products are noted so you have them on file.
Before we arrive
- Move anything stored near the joints
- For indoor joints, keep the area dry beforehand if you can
- Keep pets and children clear of the area while we work
