Fire rated sealant in Wrecclesham, done properly
Ordinary silicone or decorators’ caulk in a fire-stopping gap is not a fire-rated seal. Anything unsuitable comes out first and reseal with a fire-rated product tested for that kind of gap. Common call-outs are for open gaps behind door architraves and open holes round services passing through fire walls, on flats & HMOs, plasterboard & masonry and door frames.
Commercial work around a smaller place like Wrecclesham generally means a pub, a shop, a school or small business units rather than office blocks. Each needs the same care with its sealant as any larger building.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

Wrecclesham: your questions answered
Can you help a landlord with a rental near Farnham station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before work begins.
Is Wrecclesham within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do I have to be there?
That depends on where the joints are. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
What do you put in the joint?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Can I use normal mastic around a pipe through a fire wall?
No. A gap that needs fire stopping needs a tested fire-rated product, installed to its details.
Can you work in occupied buildings?
Yes. Occupied flats, HMOs, offices and schools are all fine, with access planned around residents or staff. Out-of-hours work can be arranged if that suits the building.
Can I add another job to the visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit.
Do you offer different sealant colours?
Most of the time, yes. We’ll explain which colours are available.
What happens if it’s left?
An unsealed gap lets smoke and fire get round a wall that was built to hold them back. Sealing it properly restores what the wall was there to do, and the work involved is often modest. Around Wrecclesham, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.

Surface by surface
Flats and HMOs
In flats and HMOs, the walls and floors between homes and common areas need sealing where services pass through. We seal the gaps your assessor has identified, flat by flat if needed.
Linear gaps
A linear joint may need to allow for movement as well as fire. The product and depth are chosen to suit both, following the tested detail.
What affects the quote in Wrecclesham
Jobs vary more than people expect. What affects the quote:
- Mould in or behind the old joints
- The size of the job
- Whether old sealant or filler has to be cut out
- How easy the joints are to reach
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we’ll go through it with you.
Helping us quote
When you contact us, it’s useful to know:
- Access, such as stairs, a lift or height
- The type of property
- The address or postcode of the job
- If someone has resealed it before
Getting a quote is simple: let us know the job and the location, and roughly how big it is. Photos by email help us understand the job, and we’ll take it from there.
How the visit works
There isn’t much for you to do on the day. Show us the job and we’ll take it from there. The work itself takes a few hours for a handful of gaps, and longer for a whole building from start to finish. In a smaller place like Wrecclesham, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- Access to each area is agreed so the work can run in order.
- We take out any damaged or unsuitable sealant.
- Dust and loose debris are cleaned from each gap.
- The fire-rated or intumescent sealant is applied and tooled to the tested detail.
- We record what was done and flag anything that needs a different system.
Preparing for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Clear the area around the work
- Mention any tricky access

Aftercare tips
To keep the joints looking good and working properly:
- Don’t fill fire-stopping gaps with ordinary foam or silicone
- File the fire-stopping record where your assessor can find it
- Take photos of fire stopping before ceilings or boxing go back
- Ask every contractor to reseal any fire stopping they disturb
Follow the cure time we give you before decorating over the sealant. Some fire-rated sealants can be painted and some can’t.
Small gaps around services are simple to deal with while there are only a few. Leave them and each new job adds another hole and the job gets bigger.
Fire rated sealant around Wrecclesham
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’re given, installing the product to its tested details.
For landlords with property near Farnham station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. If you look after a church, hall or community building such as St Peter's Church, service openings in its walls need the right fire-rated sealant, as in any building. Managing a site like St Peter's CofE Primary School? Then service openings in fire-resisting walls need checking after any refurbishment.

What else we do in Wrecclesham
DIY sealant or a professional job?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
When it is not the sealant
Before you book, it’s worth knowing the limits too:
- Big openings where sealant alone is not the tested solution
- Assessing a building’s fire safety
- A wall that isn’t a fire-resisting element to begin with
Not sure which it is? You can call 0345 464 0079 or send us an email and we’ll tell you honestly before you book.
