About our mastic sealing in Knox Bridge
Mastic Doctor has sealed joints on commercial and residential blocks since 2005. Every applicator holds a CSCS card and we hold public liability insurance. Each building we complete carries a 12-month guarantee on our workmanship. If you have a mix of products and colours from past repairs and damaged joints in communal entrances and corridors, we can help, on communal kitchens and washrooms, shopfronts below residential blocks and external wall and movement joints alike. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Knox Bridge is the same: the right product in a properly prepared joint.
Around smaller places like Knox Bridge, older walls fitted with newer windows are a familiar sight. The mastic needs to suit an irregular masonry face and the look of the building.
We stand by our work: 12 months, guaranteed. That covers our preparation and application, and if something we did falls short, we return to it.

Questions we are asked in Knox Bridge
Is a smaller place like Knox Bridge outside your area?
No. Small places get the same service as large ones. We work across Greater London and the South East. Good photos up front let us bring everything on the first visit.
Can one quote cover a number of our buildings near Knox Bridge?
Yes. Planned programmes across a building, block or estate are a core part of this service. Residents are given notice through you, and the work moves building by building.
Does weather matter for sealant work?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
How do you choose the sealant?
The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
How soon can the area be used again?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
How long does a job like this take?
It depends on the scope, though a typical visit typically takes one or more days per building, depending on the joint lengths and the access. Larger or phased jobs take longer, and we will give you a timescale with the quote.
What about access for upper-floor joints?
It depends on the building. How upper joints are reached is agreed before work is booked so there are no surprises.
When to call us in Knox Bridge
Sunlight and weather break mastic down over time. The surface chalks, the body stiffens and cracks appear, especially on south and west faces.
What tends to prompt an enquiry:
- Window mastic that has split and shrunk
- Open joints in brickwork or panels
- Draughts at frames across a block
- Communal area joints that look neglected
If you look after a block within reach of Staplehurst station, which lies north of Knox Bridge, frame and balcony mastic can be renewed on one programme.

Why it’s worth doing now in Knox Bridge
Dealing with failed joints one report at a time is slow and scattered. A planned programme treats each building once and is simpler to manage and budget. Halls, stores and units around places like Knox Bridge may not be checked every day, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

When to bring in a 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.
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.
Honest limits
A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is one of these:
- Broken glass or failed sealed units
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
- Substrate edges that need repairing first
Not sure which it is? You can phone 01277 525 020 or email drawings and photos and we will tell you honestly before you book.

Advice
Different surfaces, different methods
Tenement and older buildings
Older buildings, including Scotland’s sandstone tenements, have their own joint details. The material either side of the joint shapes the product choice.
External movement joints
Failed sealant is removed, backing rod inserted to control depth and the joint resealed with a grade whose movement class fits.
