About our external mastic in Great Tey
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible sealant bridges the two. We work on joints between brick and frames, concrete & block and façade panels, and people most often call us about damp patches traced to an open external joint and plants rooting in failed movement joints.
In a village or hamlet like Great Tey, older cottages and farm buildings often stand in the open, where walls and rooflines take the weather head on. Joints on those walls need a sealant that moves with the building and stays in place.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

The process
Before we leave, we go over the finished joints with you and explain the cure time. The work normally takes anything from a few hours to several days, depending on the building, depending on the size of the job. In a small place like Great Tey, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- We gun in low-modulus sealant and tool it neatly.
Before we arrive
- Mention any sign-in or site rules at work premises
- Let us know if you’ve seen damp or leaks
- Clear the area around the work

Advice
Signs you need external mastic in Great Tey
Sometimes a movement joint was filled with mortar or a rigid filler. With the joint locked solid, the movement turns into cracks elsewhere in the wall.
Look out for any of the following:
- Movement joints filled with mortar instead of sealant
- Gaps where render, brick and frames meet
- Brick movement joints where the sealant has split
- Sealant pulling away from one side of the joint
Letting a property close to Chappel & Wakes Colne station? Then split movement joints are easy to miss on a rental until damp shows inside.
What to look for in a quote
- How hidden problems are handled
- Which colour the sealant will be
- What the quote includes, VAT included or not
- Whether they seal over old material or remove it
For landlords and businesses
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we will quote.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.

When something else is needed
In fairness, there are a few things sealant won’t fix:
- Loose or hollow render, which needs re-rendering
- Subsidence or other structural problems
- Cracked brickwork or render that needs a builder or plasterer

External mastic in Great Tey: local notes
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Homes close to Church of St Barnabas include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep.

DIY versus a professional finish
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Surface by surface
Cladding and façade panels
Metal and composite panels move a lot with temperature, so the joints work hard every day. We choose the product to suit.
Copings and trims
Copings expand and contract through the day, so the joints need a sealant that stays flexible.
