Mastic sealing in Cock Street
Most buildings come with mastic joints nobody has looked at since handover, and it ages quietly: window perimeters, door frames, external joints and communal junctions all rely on it. When it hardens, splits or pulls away, water and draughts follow along with complaints. Most enquiries involve movement joints with sealant missing and the same joint failures repeated across a portfolio, on external wall and movement joints, balcony and threshold joints and communal kitchens and washrooms. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Cock Street, preparation and product choice get the time they need.
Around smaller places like Cock Street, older walls fitted with newer windows are a familiar sight. Perimeter mastic there has to grip an uneven face and suit the building’s character.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Looking after buildings in and around Cock Street
At about 53 miles from central London, Cock Street is within reach of the capital. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres. Rainfall across the South East, Cock Street included, is lower than in many parts of the UK. External mastic still waits for dry faces and the right temperature, and the sunniest, most exposed sides of a building normally need attention first.
Buildings close to stations like Bures station, 4 miles to the west of Cock Street, are often flats over shops, with frame mastic to keep sound. If you’re responsible for a building such as St Matthew's Church, frame and door mastic needs the same attention as any other property.

Advice
FAQs: Cock Street
Do you work for managing agents with blocks near Bures station?
Yes, we work for agents, landlords and housing associations with blocks of every size. Give us the building’s details and say how residents are notified, and we’ll quote and plan to suit.
Is a smaller place like Cock Street outside your area?
Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Good photographs up front let us bring everything on the first visit.
Is it fine to apply new sealant on top of old?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
How do you handle work on occupied blocks?
We plan around people living or working in the building. We agree the programme so you can notify occupiers and communal access is kept open.
Which sealant will you use?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Do you check for asbestos in old sealant?
We don’t remove asbestos-containing materials. Anything suspect is tested before we carry on, and the duty to manage asbestos sits with the dutyholder.
What guarantee do you give on resealing?
Our workmanship carries a 12-month guarantee, backed by public liability insurance.

Cost factors for mastic joints
These are the things that shape the price:
- How accessible the joints are
- Whether the work must be split into stages
- How much existing material needs removing
- Which sealant the job calls for
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.
Details that help us quote
To price the job accurately, we need a clear picture of the site. Useful things to include:
- How the joints are reached, and at what height
- Whether an asbestos survey exists
- Clear photos of the problem areas
- Any dates the work must fit around
Quotes are fixed against the scope you send, so the cost is agreed before work starts. To ask for one, speak to us on 01277 525 020 or send details through our quote form.
Leave it or put it right?
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. For buildings around smaller places like Cock Street, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Resealing early avoids that.
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.
What you get with us
- Public liability insurance in place
- Products installed to the manufacturer’s instructions
- Clear, fixed quotes
- Colour options checked against the specified product

What the job involves on each surface
Communal areas
We keep entrances and stairs open throughout. We work in sections so access is never blocked.
Estate-wide resealing programmes
An estate of similar buildings suits a rolling programme. Each block is priced and scheduled in order.
Should maintenance staff do it?
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
