Questions about Cooling Street
Could you schedule work at a campus like University of Greenwich - Medway for the vacation?
Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Is a smaller place like Cooling Street outside your area?
No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.
Can one quote cover more than one building?
Yes. Several buildings can share a single quote, with one point of contact.
Can you seal any opening with fire-rated sealant?
No. Sealant is the right product only where the tested detail says so. Collars, wraps, batts and boards exist for openings sealant doesn’t cover, and we flag those rather than improvise.
How soon can the area be used again?
That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
Are you fully insured?
Yes. Mastic Doctor is fully insured, public liability included.
What changes on 2 September 2029?
In England, references to the older BS 476 national classes are being removed from Approved Document B from 2 September 2029, with transitional arrangements set by the Government. The European route, BS EN 13501-2, then applies. Your designer will choose products with the right evidence.
How we handle fire stopping in Cooling Street
Sealant is the specified answer for plenty of openings, such as metal pipes, cables and some small ducts where the detail covers them. Other openings need collars, wraps, batts, pillows or boards. We use sealant where it is the specified product, and we tell you when a detail calls for something else. Most enquiries involve openings found when ceilings come down for a refit and fire seals cut back for extra cables and never reinstated, on service gaps in risers, small duct penetrations where the tested detail allows and joints between fire-resisting walls and floors. Facilities teams, main contractors and managing agents in Cooling Street tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
A job near Cooling Street is typically planned around one visit, with the specification and photographs sent in advance. Design and sign-off belong to the designer or building control; we install what’s specified.
The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

What we are called out for in Cooling Street
Head-of-wall joints and wall-to-wall junctions are frequent weak points. Deflection and building movement can open these gaps. Linear joint details set a width range and movement capability, and the seal has to sit within them.
Any of the following is a good reason to get the joints checked over:
- Service penetrations left open after M&E works
- Damaged fire seals in risers and voids
- Fire sealant pulled out of the opening
- Expanding foam used as fire stopping
Residences at universities like University of Greenwich - Medway (3.3 miles south of Cooling Street) have compartment walls that must be resealed whenever services change.
Before you book anyone
- Their pre-qualification and accreditations
- Do they follow the manufacturer’s priming guidance?
- Their approach to joint depth and backing
- Whether their applicators hold CSCS cards
Our process
Site rules come first: signing in, inductions and any permit to work. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. If others near Cooling Street need work, visits can be combined. You will have a fixed quote before work starts.
- We start with your penetration schedule, drawings or specification.
- Access, permits and the order of areas are agreed with the site team.
- We compare every service penetration with its tested detail before sealing.
- Foam, ordinary sealant and debris come out so the seal starts clean.
- Backing and fire-rated sealant are installed to the detail and tooled.
- We tell you about openings that need a different product.
What we need from you
- Explain the parking and delivery arrangements
- Send asbestos survey details if the building is pre-2000
- Let us know about inductions and permits

Advice
What sealant work can’t fix
Being straight saves everyone time. Fresh joints won’t solve:
- Plastic pipes whose detail calls for a collar or wrap
- Approving the work on behalf of building control
- Designing or specifying fire stopping, which sits with the designer or fire engineer
Not sure which it is? You can phone 01277 525 020 or send photos by email and we’ll tell you honestly.
Surfaces we seal
- Linear gaps at wall heads
- Joints between fire-resisting walls and floors
- Pipe penetrations
- Small duct penetrations where the tested detail allows
- Cable penetrations
- Service gaps in risers
Cost factors for service penetrations
We price every job individually. The main factors are:
- The size and state of each joint
- Distance, for remote addresses
- Access and working height
- The site’s rules and procedures
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.
What we need to price the job
For an accurate fixed quote, we need a clear picture of the site. Send us:
- Anything awkward about access or site hours
- The site address and postcode
- Rough lengths or quantities, or drawings if you have them
- Clear photos of the problem areas
We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To start the process, phone 01277 525 020 or email drawings and photos.
Surface by surface
Plastic pipes
Waste and drainage pipes through floors are a frequent case. Whether sealant alone is acceptable depends entirely on the tested detail, and we won’t substitute it for a specified collar.
Metal pipes
Metal pipes conduct heat, so their details often call for extra measures along the pipe. We follow whatever the detail requires and flag anything we can’t match.
Service penetrations in Cooling Street buildings
In England, Approved Document B covers fire stopping of openings and penetrations. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. Either way, we install the specified product to its tested detail. Central London is about 26 miles from Cooling Street. Office refits around the commuter belt bring new cabling through fire-resisting walls; the gaps need the specified seal.
In a school such as Cliffe Woods Primary School, fire-rated sealant goes in around service penetrations where it is specified. Older community buildings such as St James' Church that have been rewired or given new heating can have service gaps through walls worth checking against the specification.
Cooling Street is about 4 miles north of Rochester, in Medway. We send applicators to Cooling Street for service penetrations, handled exactly as we handle every other area. Our Medway coverage takes in 54 places, from busy centres to rural villages. We also cover London, some 26 miles away.
Commercial sites across ME3 are covered. We also cover Cooling (1 mile north-east), Chattenden (2 miles south-east), Wainscott (2 miles south), Lower Upnor (2 miles south) and High Halstow (2 miles east) for service penetrations.

What’s near Cooling Street
We work on buildings around The Hundred of Hoo Academy, among other places. For rail, the closest station is Higham station, roughly 2.2 miles south-west. Well-known places in the area include Huguenot Museum (3.7 miles south) and French Hospital (3.8 miles south). The countryside around Cooling Street includes Gad's Hill and Rede Common.
Leave it or put it right?
An unsealed opening affects more than fire safety: smoke, noise and draughts pass through them every day. The specified fire seal closes the gap for all of these, and the other benefits follow. Converted and older buildings near places like Cooling Street tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.
