External & façade joints in Gillingham, Medway
External mastic across Gillingham and nearby, with every bit of old sealant taken out first and a one-year guarantee.
- Brick movement joints where the sealant has split
- Weeds or debris growing in open joints
- Failed seals between different materials
How we handle external mastic in Gillingham
Low-level joints can normally be done from the ground. For joints higher up, give us some details of the building and we will confirm what’s needed to reach them safely. If you have plants rooting in failed movement joints and weathered mastic that no longer stretches, we can put it right.
Larger buildings in Gillingham have plenty of movement joints, cladding joints and roofline trims. When those fail, water gets behind the face of the building, often unseen until it shows inside.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.
What happens on the day
All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. Once we have agreed what’s being done, the area is protected and the work begins. It normally takes a few hours to a few days, depending on the length of joint and the access. Where a business in Gillingham needs to stay open, out-of-hours working can be arranged, and homes are booked within our usual hours, Monday to Saturday.
- We start by walking round the building and agreeing the joints and the access.
- We cut out the old mastic and rake out anything in the joint.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
How to prepare
- Plan for the work area to be out of bounds to pets and children
- Let us know about earlier repairs to the joints
- Clear the area around the work

When it is not the sealant
New sealant cannot fix everything, and we’d rather say so up front. It won’t solve:
- Walls that need new movement joints cut into them
- Failed render or damaged cladding panels
- Rising or penetrating damp from elsewhere in the wall
Not sure which it is? You can ring 0345 464 0079 or send us an email and we will tell you honestly.
Joints and surfaces we work on
- Copings & trims
- Render & cladding joints

What affects the quote in Gillingham
There’s no set price list, because no two jobs are the same. What we look at:
- Whether old sealant or filler has to be cut out
- Any working-time requirements on site
- How easy the joints are to reach
- The number and length of the joints
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we’ll go through it with you.
What to tell us for a quote
Photos by email are helpful but not essential. Please mention:
- If it’s domestic, commercial or a hotel
- Pictures of the joints, sent by email
- Access, such as stairs, a lift or height
- Any previous sealing or DIY work
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is. Whenever you’re ready, ring 0345 464 0079 or send us an email.
For landlords and businesses
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.
Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Leave it or put it right?
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That protects surfaces like brick, render and concrete. Too stiff a sealant can pull at the edges and break them. In a busy place like Gillingham, a failed joint in a flat or office can send water into the space below, where it can go unnoticed until the damage is done.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
Why book with us
- More than 20 years in sealant work
- ARBOMaster approved applicator
- A 12-month guarantee on all work
- Homes, businesses and hotels

Common questions in Gillingham
Is Gillingham in your area for external mastic?
Yes. Our work covers London and the South East, and Gillingham is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job, and we’ll give you a clear quote.
I let a flat near Gillingham (Kent) station. Can you help?
Yes, landlords and agents are among the people we work for. You can phone 0345 464 0079 or email us with the details for a clear quote.
Where is Mr Mastic based?
Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.
Can a movement joint be filled with mortar?
No. Cement or mortar cannot stretch. Where a joint has been mortared, it can often be raked out and sealed properly.
When is the sealant fully cured?
Most sealants are touch-dry well before they’re fully cured. We will tell you how long to leave the joint.
How much does external mastic cost in Gillingham?
We do not publish prices, because the cost depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Why do you put foam in the joint first?
That is backing rod, a closed-cell foam. It stops the sealant going in too deep and bonding to three sides.
Is it messy?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.

Gillingham buildings and the weather
Gillingham is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. With historic houses such as Restoration House (about 3.3 miles west) nearby, there’s older building stock in the area around Gillingham as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
If you look after a building such as Featherby Junior School, larger buildings have long runs of movement joint that eventually need resealing. For landlords with property near Gillingham (Kent) station, failed wall and movement joints let damp in, so they’re worth checking between tenancies. In the older streets around Holy Trinity Church, older walls, gutters and the joints where extensions meet them need a flexible sealant.

How the job changes by surface
Concrete and blockwork
Concrete and block walls shrink as they dry and move with temperature. We reseal their joints with backing rod and a flexible product.
Copings and trims
Metal and stone copings both move with temperature, so the joints need a sealant that stays flexible.
Looking after it afterwards
A little care helps the new joints last. We recommend:
- Leave the joints unpainted unless we’ve said otherwise
- Deal with leaking gutters that soak the joints below
- Keep soil, plants and ivy away from the joints
- Get split or bare joints resealed while the damage is small
Only paint over the joint if we’ve confirmed the sealant can take paint. Paint can crack on a flexible joint.
Act while the splits are small. At that stage it’s a simple cut out and reseal before water has had years to get in.
