Aftercare for building managers
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Ask which product is in place before decorating
- Include service cupboards in routine inspections
- Keep product data and details in the fire safety file
- Settle who seals which penetrations at the start of a project
Store the specified product details somewhere the next contractor can find them. It makes later repairs much easier to match.
Write fire stopping into the scope of any work crossing a compartment wall or floor. Then the seal goes in while the area is open instead of being left for someone else.
Fire stopping in Chipping Ongar, 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. We fit the specified fire-rated sealant following that specification and the maker’s installation guidance on buildings around Chipping Ongar. If you are dealing with damaged fire seals in risers and voids and fire-rated sealant that has cracked or shrunk back, we can put it right, on joints between fire-resisting walls and floors, pipe penetrations and small duct penetrations where the tested detail allows alike. Most enquiries from Chipping Ongar start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.
Around smaller places like Chipping Ongar, many commercial buildings are conversions or extensions of older ones, so the wall or floor a service passes through isn’t always what the drawings assume. The right product depends on the wall or floor and the services passing through, and we’ll tell you if the detail calls for something other than sealant.
The 12-month guarantee is for workmanship rather than 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.

Site staff or a sealant specialist?
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.
Where services cross fire walls in Chipping Ongar
For England, the fire stopping of penetrations is dealt with in Approved Document B. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. Either way, we install the specified product to its tested detail. At about 20 miles from central London, Chipping Ongar is within reach of the capital. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls.
Where a unit on an estate such as Hallsford Bridge Industrial Estate, 0.9 miles south-east of Chipping Ongar, has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail. In a building such as United Reformed Church, any service penetration through a fire-resisting wall should be sealed to the specified detail.

What tends to prompt an enquiry:
- Fire-rated sealant that has cracked or shrunk back

- Builders’ foam or ordinary silicone in compartment walls
- Snag lists that include open service penetrations
Holiday works at schools like Chipping Ongar Primary School often leave service openings to seal before pupils return.

Why deal with it now?
Inspections and handover checks often pick up fire stopping. Late discoveries can delay handover while openings are reopened and resealed. In a smaller place such as Chipping Ongar, getting a contractor back for a second visit takes time, so we’d suggest renewing all the joints that are going, not just the worst.
There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we’ll price your job on its own details.

Your questions answered
Is Hallsford Bridge Industrial Estate, near Chipping Ongar, within your area?
Yes. Our area takes in Chipping Ongar and its surroundings, with estates and business parks such as Hallsford Bridge Industrial Estate included. A few photographs and the unit address let us price the work.
Is Chipping Ongar off your patch?
Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Good photographs up front let us bring everything on the first visit.
Are you insured?
Yes. Mastic Doctor is fully insured, public liability included.
Do you seal on top of existing sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
Who decides which product is used?
A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Can the sealant be colour-matched?
Often, 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.
Can you quote from photos?
Many jobs can be quoted from photos, drawings or a joint schedule. If the job needs a look first, we’ll arrange a visit.
