Common problems we fix in Farringdon
Sometimes the wrong product was used from the start: ordinary expanding foam, standard silicone or decorators’ caulk in a place that needed a tested fire seal. It looks sealed, but it isn’t fire-rated.
Look out for these signs:
- Gaps around pipes and cables through fire-resisting walls
- Open gaps behind door architraves
- Fire stopping disturbed by later work
- Gaps left after a refit or conversion
Community buildings like Church of All Saints are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building.

What fire rated sealant looks like in Farringdon

Why act early in Farringdon
An open gap in a fire-resisting wall is a route for smoke and fire. Sealing it properly restores what the wall was there to do, and the sealing itself is often a contained piece of work. Older cottages and farmhouses around Farringdon can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

DIY sealant or a professional job?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
How it works
Before we leave, we go over the finished joints with you and tell you how long to leave it. The work normally takes from a few hours to a few days, depending on the number of gaps and the access, depending on how much there is to do. For a village or hamlet like Farringdon, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- Access to each area is agreed so the work can run in order.
- Old, damaged or unsuitable sealant is removed.
- Dust and loose debris are cleaned from each gap.
- The fire-rated or intumescent sealant is applied and tooled to the tested detail.
- Locations and products are written up and any gaps unsuitable for sealant are flagged.
Before we arrive
- On commercial sites, let us know about site rules
- Let us know about stairs, lifts or work at height
- Clear items away from the joints we are working on

Your questions about fire rated sealant in Farringdon
Is Farringdon within the area you cover?
Yes. Farringdon is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Where is Mr Mastic based?

Do you certify the fire stopping?
That isn’t something we state or certify. Your specification sets the requirement, and we fit a product whose tested details meet it, recording the locations and products.
Is it OK to seal over old sealant?
No. New silicone won’t bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Can I do it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Is there any odour?
Sometimes, a little. It fades as the sealant cures.
Can you give us a record of the work?
Yes. Locations and products are written up when we finish. Tell us if your assessor needs it in a particular format.
What the job involves on each surface
Plasterboard walls
We check that the board around the gap is sound. Crumbling edges are cleaned back before the sealant goes in.
Door frames
Behind most architraves is a gap between frame and wall. We seal any open gap to the product’s tested details.
