Fire stopping in Keeper's Corner
A fire-rated sealant is only one part of a tested system: its test evidence covers one product in one kind of wall or floor, with set services, gaps, depths and backing. Before we seal anything, we check the opening against the detail it is meant to follow. Most enquiries involve fire stopping installed outside its tested range and fire-rated sealant that has cracked or shrunk back, on service gaps in risers, joints between fire-resisting walls and floors and small duct penetrations where the tested detail allows. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Keeper's Corner, preparation and product choice get the time they need.
Barn and farm-building conversions near places like Keeper's Corner often combine new partitions with old walls. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.

What sealant work can’t fix
We check first that sealant really is the fix. It isn’t the answer for:
- Signing off or certifying a building’s fire stopping
- Fire risk assessments, a job for a competent assessor
- Openings that need collars, wraps, batts or boards rather than sealant
If you are not sure, just speak to us on 01277 525 020 or send photos by email and we’ll give you a straight answer.
Surfaces we seal

Questions we’re asked in Keeper's Corner
Do you seal service penetrations in hotels around Keeper's Corner?
Yes, where fire-rated sealant is the specified product. It goes in to the manufacturer’s tested detail for the wall or floor and the services passing through, and we’ll tell you if the detail calls for a collar, wrap or batt instead.
Do you take on work at healthcare sites like Langley Green Hospital?
Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Are you CHAS accredited and on Constructionline?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
Can you handle several sites?
Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.
Does the weather affect the work?
Outside, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.
What if there’s asbestos in the old mastic?
Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.
Are your applicators CSCS-carded?
Yes. Should the site need card details in advance, let us know and we’ll send them with the quote.
Looking after the joints
To get the most from the new sealant:
- Check risers and ceiling voids after each round of works
- Have penetrations checked while they can still be seen
- File the specified details where the next contractor can find them
- Agree the fire-stopping specification before services go in
Never top up a fire seal with foam, ordinary silicone or filler. Repairs need the same product and detail as the original, or a new specification from the designer.
Specify fire stopping early on refits, not as an afterthought. The designer can then choose details that suit the services planned, and installation follows the programme.
Do you need fire stopping in Keeper's Corner?
Linear gaps fail where a fire-resisting wall meets a slab, soffit or another wall. Movement in the frame or slab can open the joint, and a product not tested for that movement may crack. Linear joint details set a width range and movement capability, and the seal has to sit within them.
Typical triggers for a call:
- Fire-rated sealant that has cracked or shrunk back
- Unsealed joints where partitions meet the slab
- Fire-stopping items raised at inspection or handover
- Seals that don’t match their tested detail
In a hotel such as Copthorne Hotel Effingham Park, 1.1 miles south-east of Keeper's Corner, new pipework or cabling through bedroom and corridor walls needs sealing with the specified product.
What to look for in a quote
- What site paperwork they can supply
- Can the work be phased to keep areas open?
- Proof of insurance
- How the joint faces will be prepared and primed
Leave it or put it right?
A seal that doesn’t match its tested detail gives false comfort. The fix is to remove it and reinstall to the detail. For buildings around smaller places like Keeper's Corner, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.
What a job costs comes down to the quantity of joints, how much old material needs removing and the access. Call for a quote when you’re ready.
Why us?
- Fully insured, including public liability cover
- Constructionline member for supplier checks

Site staff or a sealant specialist?
Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Diagnose, treat, sign off
Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. On site, the work usually takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence, and our waste is bagged and taken away as we go. Rural sites near Keeper's Corner may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.
- First we confirm the product and tested details named in the specification.
- We sort the openings by the detail each one needs.
- Old or wrong materials are cut out.
- Where the detail needs backing, it goes in at the stated depth.
- We gun the sealant in to the specified depth around each service and tool it.
- We walk the completed areas with you and confirm the records agreed at quote stage.
What we need from you
- Tell staff and tenants when we’ll be in
- Point out any areas we must not close
- Share the asbestos register for older buildings
