How we handle external mastic in Finglesham
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Some surfaces need a primer before sealing and we use one wherever it does. We work on copings & trims, concrete & block and joints between brick and frames, and people most often call us about failed seals between different materials and panel joints letting water in.
In a village or hamlet like Finglesham, 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.
Each job carries a 12-month guarantee, whatever its size.

What affects the cost of external mastic
Your quote is based on your job. We look at:
- Whether old sealant or filler has to be cut out
- Whether the work is at height
- Working hours on commercial sites
- How many areas need sealing
Doing several joints on one visit is normally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We’ll send you a clear quote for the lot.
Helping us quote
There’s no need for technical detail. Just tell us:
- Roughly how big the job is
- The problem you’ve noticed
- Access, such as stairs, a lift or height
- Where the job is, and your postcode
Getting a quote is simple: let us know the job and the location, and roughly how big it is. A few photos by email make the job easier to understand, and we’ll come back to you with a quote.
Why deal with it now?
An open joint keeps letting water into the wall with every downpour. Wet masonry is more easily damaged by frost around the joint, so the problem grows beyond the joint itself. Older cottages and farmhouses around Finglesham can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Why us?
- We agree the colour with you first
- Anti-fungal silicone where joints get wet
- Domestic, commercial and hotel work
- ARBOMaster approved applicator
How the visit works
We keep the work tidy and contained to the joints we’re treating, so you can carry on as normal. The job generally takes anything from a few hours to several days, depending on the building, and we tell you how long to leave it before we go. Somewhere as small as Finglesham, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we look over the joints with you, agree which to renew and talk through access.
- The old mastic and anything lodged in the joint is removed.
- We clean both faces of the joint and prime them where the product calls for it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
How to prepare
- Try not to wet indoor joints just before the visit
- Keep pets and children clear of the area while we work
- Mention any sign-in or site rules at work premises

Common problems we fix in Finglesham
A lot of failed joints come down to preparation: dusty or wet faces, no primer where one was needed, or old sealant left in. The sealant never bonds properly.
Any of these means the joints need attention:
- Joints with sealant missing in places
- Rain getting behind render or cladding at a joint
- Panel joints letting water in
- Hard, crazed mastic that has stopped moving
Managing a site like Northbourne Church of England Primary School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
What to look for in a quote
- What happens if they find a problem under the old sealant
- Is the old sealant removed completely?
- Is VAT in the price?
- Are they insured?

Common questions in Finglesham
Can you help a landlord with a rental near Sandwich station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just phone 0345 464 0079 or email us with the address and what needs doing, and we will give you a clear price.
Do you cover smaller places like Finglesham?
Yes. Finglesham is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you do commercial work?
Yes. Larger jobs can be planned room by room or area by area.
Will you leave a mess?
No. The area is protected while we work and cleaned up afterwards.
Where do you work from?
Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.
Will the old sealant be removed?
Yes, every time. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
Does someone need to be in?
If the work is inside, we need someone to let us in. Once we have agreed the job, you don’t need to watch us work.
Do you seal joints where cladding meets other materials?
Yes. Where different materials meet is one of the most common joints we seal. The sealant is chosen to bond to both sides with primer where required.
DIY versus a professional finish
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Walls and rooflines in Finglesham
Finglesham is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. Historic houses like Walmer Castle (about 3.4 miles south-east) are a reminder that the area around Finglesham has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
Rented homes near Sandwich station change hands often, and split movement joints are easy to miss on a rental until damp shows inside. In the older streets around Church of St George, older walls, gutters and the joints where extensions meet them need a flexible sealant.
