How we handle fire rated sealant in Longford
A fire seal relies on being installed the way it was tested: correct depth, correct backing and a product suited to the surfaces. That detail is what we take care over, gap by gap. We work on pipe & cable gaps, service penetrations and door frames, and the jobs we see most are fire stopping disturbed by later work and gaps left after a refit or conversion.
For holiday lets, converted business premises or a community building near Longford, the washrooms, kitchens and any fire-rated joints need the same care as a big site.
Big or small, you get the same 12-month guarantee in Longford and across Slough.

Signs you need fire rated sealant in Longford
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.
It’s worth asking for a quote if you see:
- Ordinary sealant used where a fire-rated product was needed
- Open holes round services passing through fire walls
- New service routes left unsealed after building work
- Fire stopping disturbed by later work
Managing a site like Pippins School? Then service openings in fire-resisting walls need checking after any refurbishment.

Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
What happens if it’s left?
Waiting for the next refit can leave a gap open for years. Sealing the gap now is a contained job on its own that does not depend on other work. In a small place like Longford, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
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’ll get one clear quote for the whole job.

Workplaces and buildings in Longford
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. Longford has hotels and guest accommodation in and around it. Hotel work can be planned room by room, with out-of-hours working where needed.
For buildings such as Church of St Mary, gaps around pipes and cables are worth checking after any building work there. Rented homes near Heathrow Terminal 5 Rail station change hands often, and any gap left by new services in shared walls should be closed with a fire-rated product.
Longford is about 2 miles south-west of West Drayton, in Slough. Longford gets the same service as everywhere we cover: old sealant removed completely, careful preparation and a 12-month guarantee. Our area takes in 31 places across Slough, large and small. There’s also a page for London, roughly 17 miles from Longford.

Local landmarks in Longford
Around Longford, our work takes us to homes and buildings near The Kings Arms and Arthur Jacob Nature Reserve, among other places. For rail, the closest station is Heathrow Terminal 5 Rail station, about 0.5 miles south-east of the centre. Well-known places in the area include Windsor Castle (4.8 miles west) and Harlington (2.1 miles north-east). Not far away are Crane Meadows and Staines Reservoirs.
Looking after it afterwards
A little care helps the new joints last. Our advice:
- Include hidden areas like risers in routine checks
- Include fire stopping when you schedule refits
- Keep general-purpose foam and caulk away from fire-stopping gaps
- Keep pictures of seals that will be hidden
Avoid covering a sealed gap with anything that isn’t part of the tested detail. Repairs should use a matching fire-rated product. Ask us if you’re not sure which product was used.
A gap left open in a fire-resisting wall or floor lets smoke spread in ways the building wasn’t designed for. Sealing it early is a simple step to take.
What affects the quote in Longford
Every job gets its own quote. This is what makes a difference:
- How much old sealant there is and how hard it is to remove
- The size of the job
- Which sealant suits the joint
- How many rooms, windows or areas are involved
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.
Asking for a quote
When you call or email, these details help:
- The rough size of the job
- Access, such as stairs, a lift or height
- Where the property is
- The problem you’ve noticed
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and email photos if that’s easy.
Longford: your questions answered
Will you come out to Longford?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Can you help a landlord with a rental near Heathrow Terminal 5 Rail station?
Yes. We work for landlords and agents as well as homeowners. You can call 0345 464 0079 or drop us an email with the details for a clear quote.
Is it messy?
No. We protect the surfaces around the joints, and we tidy up before we go.
Do you guarantee your work?
Yes, for a year. If anything isn’t right with the work within the year, let us know and we’ll sort it.
What sealant do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice.
Do you provide details of the products used?
Yes. We note each location and the product that went in so it’s there for the next inspection.
Do the sealants smell?
Some sealants have a smell while they cure. Opening a window helps.
What’s the difference between intumescent and fire-rated sealant?
Fire-rated sealant covers any sealant tested for use in fire stopping. Intumescent types expand when heated, and they’re one option among several. We use whichever the specification and tested details call for.
How it works
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and clear up. Most jobs take a few hours for a handful of gaps, and longer for a whole building. Somewhere like Longford needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- Before starting, we go through the specification or action list with you.
- Each gap is measured and its substrate and service noted.
- Any non-fire-rated filler is removed and the gap cleaned.
- We fit backing where needed and apply the fire-rated sealant to depth.
- We hand over a list of locations and products for your files.
Getting ready for the visit
- Let us know if you’ve seen damp or leaks
- Let us know about stairs, lifts or work at height
- Mention any parking rules near the property
