Maintenance after handover
Once the work is signed off, these steps help:
- Have penetrations checked while they can still be seen
- Include service cupboards in routine inspections
- File the specified details where the next contractor can find them
- Check with the data sheet before painting over fire sealant
After every round of M&E works, check that the openings created have been sealed. Building it into each contractor’s sign-off keeps the walls intact.
Make reporting new openings part of every permit to work in service areas. Small habits like this stop openings building up.
Fire stopping in Sandling, done properly
Opened ceilings and riser doors often reveal service openings nobody sealed. If a specification already covers those walls and floors, we can reseal to it, matching the product and detail it names. With no specification in place, the first step sits with your designer or fire engineer, not with us. The enquiries we see most involve fire sealant pulled out of the opening and head-of-wall gaps with no fire seal, on pipe penetrations, service gaps in risers 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 Sandling, preparation and product choice get the time they need.
Barn and farm-building conversions near places like Sandling often combine new partitions with old walls. A penetration seal only performs as tested if product, substrate, service, gap and depth all match the detail.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

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. Halls, stores and units around places like Sandling may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.

Questions we’re asked in Sandling
Can you work on a hospital site such as Royal Victoria Hospital?
Yes, healthcare and care buildings are part of our work. Each area is agreed with the ward or department and the estates team in advance.
What does the BS 476 change mean for fire-rated sealant in Sandling?
References to BS 476 classes are being removed from Approved Document B from 2 September 2029, after which BS EN 13501-2 classification is the route, subject to transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.
What’s the quickest route to a quote?
You can use the quote form on this site; alternatively, give us a call on 01277 525 020 or email the details over. Include photos or drawings if you have them.

Are you CHAS accredited?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
Do you guarantee your work?
Yes. Our workmanship is backed for 12 months on every job.
Do you seal on top of existing sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
On site: what to expect
Occupied buildings need a little choreography. We sign and contain the area we’re in, keep walkways clear and work section by section so the rest of the building stays in use. If others near Sandling need work, visits can be combined. You will have a fixed quote before work starts.
- We ask for the product and detail your designer has specified.
- Openings are measured and grouped by detail.
- Improvised fillers and failed sealant are removed.
- 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.
Getting the site ready
- Make sure the joints can be reached
- Send asbestos survey details if the building is pre-2000
- Point out any areas we must not close

Honest limits
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Large openings beyond what any sealant detail covers
- Gaps in walls that were never built as compartment walls
- Deciding what a wall or floor needs, which belongs to the designer
If in doubt, call the office on 01277 525 020 or send details through our quote form and we’ll say what we think.
Joints and surfaces we work on
- Small duct penetrations where the tested detail allows
- Linear gaps at wall heads
- Cable penetrations
- Pipe penetrations
- Service gaps in risers
- Joints between fire-resisting walls and floors

Fire-rated sealing for Sandling buildings
Central London is about 58 miles from Sandling. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls. There are four care or nursing homes within about 2 miles of Sandling. Where new services have gone through compartment walls in a care setting, the gaps need the specified product. Where that’s fire-rated sealant, we install it to the manufacturer’s tested detail.
Halls and meeting rooms at places like Church of St Peter and St Paul sometimes gain new services, and any compartment wall crossed needs the specified seal. Hotels such as The Swan Hotel (to the south-east of Sandling) rely on fire-resisting walls between bedrooms and corridors, and refits that add services leave penetrations to seal where fire-rated sealant is specified. Theatres, wards and plant rooms at sites like Royal Victoria Hospital, 4.6 miles east of Sandling, all have compartment walls crossed by services.

General trades versus a specialist
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
How the job changes by surface
Cables and cable bundles
Cable penetrations are frequently sealed with fire-rated sealant where the detail allows. Bundle size, cable type and the space between cables all matter, so we check before sealing.
Small ducts
Ducts are only sealed with sealant where the detail allows it. The ductwork, its supports and any dampers are for the ductwork contractor.
