External mastic for homes and businesses in Tidebrook
A movement joint is only as good as its depth. Backing rod controls how deep the sealant goes and keeps it off the back of the joint, so it bonds to the two sides only and can stretch. We’re often asked to deal with brick movement joints where the sealant has split and moss and dirt in joints with no sealant left, on copings & trims, façade panels and joints between brick and frames.
In a village or hamlet like Tidebrook, older cottages and farm buildings often stand in the open, where walls and rooflines take the weather head on. Gutter joints and wall joints there need a sealant that can flex and stay put.
We stand behind the work with a 12-month guarantee, so you are not left on your own once the job is done.

What the job involves on each surface
Copings and trims
Metal and stone copings both move with temperature, so a flexible sealant suits them best.
Joints between dissimilar materials
Each side of the joint may need its own preparation. We prepare both faces so the sealant bonds properly.
FAQs for Tidebrook
Is Tidebrook in your area for external mastic?
Yes, Tidebrook is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or drop us an email and let us know what needs doing.
Do you work for landlords with property near Wadhurst station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
How much does external mastic cost in Tidebrook?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote and we will talk you through it.
What is a movement joint?
Brickwork, render and cladding all move a little, so long walls have planned gaps to take that movement. It’s closed with backing rod and a flexible sealant.
What information do you need?
Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.
Can a movement joint be filled with mortar?
No. Mortar locks the joint solid, so the movement cracks the wall elsewhere. Use a flexible sealant with backing rod.
Is it OK to seal over old sealant?
No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. We remove it all first.
What sealant do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.
How we quote for external mastic
The quote reflects the job in front of us. We look at:
- Mould in or behind the old joints
- Access and height
- When we can work, for business premises
- The old material and how stubborn it is
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part.
Asking for a quote
Before you ask for a quote, have a think about:
- Whether it has been sealed before
- Photos by email, if that is easy
- Any access issues, like height or stairs
- What the problem is, such as mould, gaps, leaks or cracking
Asking for a quote is easy: tell us what needs doing and where and its rough size. A few pictures by email make the job easier to understand, and we’ll take it from there.
For landlords and businesses
We work for landlords and agents as well as homeowners. Sealant work between tenants keeps a property looking cared for before the next move-in.
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
Tidebrook buildings and the weather
With historic houses such as Wadhurst Castle (about 2.3 miles north-east) nearby, there’s older building stock in the area around Tidebrook as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth. 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.
For landlords with property near Wadhurst station, failed wall and movement joints let damp in, so they’re worth checking between tenancies. Homes close to The Parish Church of St John the Baptist include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move.

How the visit works
A visit follows a simple pattern: we check the joints, protect the area around them, carry out the job and clear up. It normally takes anything from a few hours to several days, depending on the building. In a small place like Tidebrook, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
How to prepare
- Mention if the joints have been sealed before
- Let us know about stairs, lifts or work at height
- Let us know about parking restrictions

Signs you need external mastic in Tidebrook
The wrong product in a moving joint is a classic cause. A stiff, general-purpose sealant can’t cope with a joint that moves a lot, and it tears off the sides.
Keep an eye out for these signs:
- Water getting into walls through failed joints
- Old sealant gone brittle and cracked
- Moss and dirt in joints with no sealant left
- Joints pointed up with cement by mistake
If you look after a building such as Uplands Community College, larger buildings have long runs of movement joint that eventually need resealing.
Questions to ask before you book
- Whether VAT is included
- What preparation is included
- How long to leave it before use
- Which colour the sealant will be
DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
Why act early in Tidebrook
It often makes sense to reseal all the failing joints on an elevation together. They’ve weathered the same way. Older cottages and farmhouses around Tidebrook can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Combining jobs into one visit generally makes better use of the time than several visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.
