How the job changes by surface
Small ducts
Small ductwork can sometimes be sealed with sealant where the tested detail includes it. Bigger ducts and fire-resisting ductwork are normally handled with other products.
Drylining partitions
Drylined fire walls are tested in a particular build-up. We check that the product’s detail covers that partition type and board thickness.
Fire stopping in Upper Heyford, done properly
We should be clear about what we do and don’t do. Deciding the specification sits with the designer, the fire engineer and building control. What we bring is careful installation of the specified sealant, to the maker’s guidance in Upper Heyford and nearby. The enquiries we see most involve damaged fire seals in risers and voids and open linear gaps along the top of fire-resisting walls, across service gaps in risers, cable penetrations and linear gaps at wall heads. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Upper Heyford is the same: the right product in a properly prepared joint.
In places the size of Upper Heyford, fire-resisting walls and floors are found in schools, care homes, health centres and mixed-use buildings. Around those penetrations, fire-rated sealant is installed if specified, with depth, backing and gap all as tested.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

FAQs: Upper Heyford
Does your area include sites such as Hatch End Old Industrial Estate, near Upper Heyford?
Yes. Our area takes in Upper Heyford and its surroundings, with estates and business parks such as Hatch End Old Industrial Estate included. Photos and a short description are enough for a first look.
How does the removal of BS 476 from Approved Document B affect fire-rated sealing in Upper Heyford?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.
When can the area be used after sealing?
Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.
What happens if old sealant might contain asbestos?
The duty to manage asbestos sits with the building’s dutyholder, so we will ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.
Is any job too small?
Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.
Do you have public liability insurance?
Yes. Mastic Doctor is fully insured, public liability included.
Is colour matching possible?
In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We’ll confirm the colours available for the specified product.
Aftercare for building managers
Cleaning and maintenance staff play a part too. Pass these on to them:
- Make fire stopping part of every scope that crosses a fire-resisting wall
- Look above ceilings when tiles are lifted for other jobs
- Record which product was used where
- Report damaged or disturbed seals as soon as they’re spotted
Once the seals are in, tell other trades they exist and must not be disturbed. Any seal cut back for a new service needs reinstating to its tested detail using the same product.
The simplest way to keep compartment walls intact is to plan fire stopping into every job that crosses them. That way the opening is sealed while the trade and access are still there, not months later.
Diagnose, treat, sign off
Before we leave any area, we remove the tape, clean down and inspect every joint. If an area should be left alone while the sealant cures, we say how long and put signs out. What matters most for a job in Upper Heyford is a clear list of what needs doing. A fixed quote follows.
- First we confirm the product and tested details named in the specification.
- Openings are measured and grouped by detail.
- 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
- Share the asbestos register for older buildings
- Warn occupants and staff about the work
- Share your working hours and any access restrictions

Leave it or put it right?
Inspections and handover checks often pick up fire stopping. Finding unsealed or improvised openings late can hold up a programme. Over time, UV, weather and movement wear any sealant out. Renewing it in good time keeps the building weathertight.
A quote for service penetrations depends on how many there are, their condition and the access, and any specification that applies. Call for a quote.

Penetration seals near Upper Heyford
For England, the fire stopping of penetrations is dealt with in Approved Document B. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. What we install is set by the specification, and it goes in to the tested detail. Upper Heyford is about 58 miles from central London. Office refits around the commuter belt bring new cabling through fire-resisting walls.
For a building such as Heyford Park Chapel, new heating or data runs are the usual reason penetrations need sealing. For a hospital such as Bicester Community Hospital, 4.8 miles south-east of Upper Heyford, penetration sealing is usually phased ward by ward, with infection-control rules agreed first.

What we are called out for in Upper Heyford
Damage plays a part too. Maintenance work can knock a seal, cut it back for an extra cable or remove it with an old pipe, and the repair is often skipped.
Clients typically get in touch after noticing one or more of the following:
- Fire sealant pulled out of the opening
- Open linear gaps along the top of fire-resisting walls
- Penetration schedules that need working through
- Expanding foam used as fire stopping
On estates like Hatch End Old Industrial Estate, which lies west of Upper Heyford, the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal.
