Fire rated sealant in Woldingham, done properly
Deciding which gaps need fire stopping is not our role; that comes from your fire risk assessor, designer or building control. Our part is applying the specified sealant carefully, to the right depth and with the right backing. If you have ordinary sealant used where a fire-rated product was needed and new service routes left unsealed after building work, we can help, whatever the surface.
Somewhere as small as Woldingham, commercial jobs tend to be pubs, holiday lets, farm buildings or halls rather than offices. Each still needs sound sealant in its washrooms and kitchens, and fire-rated joints where services pass through walls.
Whatever the size of the job, it’s backed by our one-year guarantee.

DIY sealant or a professional job?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.

Common questions in Woldingham
Can you do fire rated sealant in Woldingham?

I let a flat near Woldingham station. Can you help?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before any work starts.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Do the sealants smell?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.
Do you remove the old sealant?
Yes, every time. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
Do you work in flats, HMOs and commercial 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.
Is intumescent sealant the same as fire-rated sealant?
Fire-rated is the broad term for sealants tested for fire stopping. Intumescent ones swell in heat, and they’re one of the options. The specification and the tested detail decide which is used.

Surface by surface
Linear gaps
Gaps along the top of partitions are easy to miss above a ceiling. We work along the whole run leaving no stretch unsealed.
Service penetrations
Wherever a service goes through a fire-resisting wall or floor, there’s a gap around it. We seal it with a product tested for that service and gap size.

Workplaces and buildings in Woldingham
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, and gaps around services are often picked up there. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
For landlords with property near Woldingham station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. Community buildings like Church of St Paul are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking.

Aftercare tips
To keep the joints looking good and working properly:
- Make resealing part of every contractor’s brief
- Photograph sealed gaps before they’re covered up
- File the fire-stopping record where your assessor can find it
- Don’t fill fire-stopping gaps with ordinary foam or silicone
Tell other trades that the gaps have been sealed, and make sure anything they disturb is resealed with a suitable product. Later work is a common cause of damaged fire stopping.
It’s easiest to seal gaps while they’re few and easy to reach. Over time, more work adds more holes and the job gets bigger.
Signs you need fire rated sealant in Woldingham
Many open fire-stopping gaps are made after the building is finished. Electricians, plumbers and data installers drill through walls and ceilings and the hole round the new service is not always sealed again.
If you can see any of these, it’s time to have the joints looked at:
- Gaps where walls meet ceilings or slabs
- Sealant items on a fire risk assessment action list
- Unsealed gaps where pipes and cables go through a wall
- Old fire sealant that has split or come away
If you look after a building such as Woodlea Primary School, service openings in fire-resisting walls need checking after any refurbishment.

How it works
All our tools and materials come with us in the van, so there’s nothing for you to buy. After a quick look at the joints together, the area is protected and the work begins. It normally takes from a few hours to a few days, depending on the number of gaps and the access. In a small place like Woldingham, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we work through your list or survey, measuring each gap and checking what it’s formed in.
- 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
- Tell us about any previous sealing or DIY attempts
- Let us know about parking restrictions
- Keep pets and children clear of the area while we work
