- Movement joints filled with mortar instead of sealant
How it works
Most of a good job is in the preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it normally takes anything from a few hours to several days, depending on the building. A visit to The Hythe is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- Backing rod goes in so the sealant can stretch between the two faces.
- We prime the faces where required.
- We gun in low-modulus sealant and tool it neatly.
Before we arrive
- Let us know about stairs, lifts or work at height
- Clear the area around the work
- Tell us if parking is tricky

External mastic for homes and businesses in The Hythe
Many failed façade joints only get noticed once there’s a stain or a damp patch inside. We look over the joints, agree the ones to renew and reseal with a flexible, weatherproof product in a matching colour. If you’re dealing with sealant that has lost its bond to the brick or render and rain getting behind render or cladding at a joint, we can help.
Houses in smaller places like The Hythe can stand more in the open than those in a built-up town, and walls and rooflines facing the weather take the worst of it. Joints on those sides are generally the first to go.
All our work comes with our 12-month guarantee, wherever you are in Essex.

What affects the quote in The Hythe
The quote reflects the job in front of us. We look at:
- Whether the work is at height
- Mould in or behind the old joints
- The size of the job
- 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, and we’ll explain the quote if you ask.
What we need to know
There’s no need for technical detail. It helps if you can tell us:
- How many joints, rooms or windows are involved
- Any previous sealing or DIY work
- What the problem is, such as mould, gaps, leaks or cracking
- Pictures of the joints, sent by email
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and add pictures by email if you can.
Why it’s worth doing now in The Hythe
Low-modulus sealants stretch easily, so they put less strain on the joint edges. That matters on brick, render and concrete, which can be weaker at the face. Too stiff a sealant can pull at the edges and break them. Homes in smaller places like The Hythe can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you are not sure whether it needs doing, ring 0345 464 0079 or email us and we will give you an honest view and a quote.

Common questions in The Hythe
Can you do external mastic in The Hythe?
Yes. We work across London and the South East, and The Hythe is part of that. You can call 0345 464 0079 or email us and tell us what needs doing.
Do you work for landlords with property near Hythe station?
Yes, landlords and agents are among the people we work for. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Why is there a gap in my brick wall?
A vertical gap in a long brick wall is generally a movement joint. It lets the bricks expand without cracking, and it should be sealed with a flexible sealant.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
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.
Do the sealants smell?
That depends on the sealant. Some products have a noticeable smell, others very little.
Do you remove the old sealant?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
What colours does the sealant come in?
Exterior sealants are made in a range of colours, from greys and browns to whites and stone shades. We choose the closest to your brick or render so the joint does not draw the eye.
Work for landlords, hotels and businesses
Mouldy or split sealant often shows up at the end of a tenancy. Several properties can go on one quote.
In hotels, rooms out of use cost money, so the work can be planned room by room. We’ve worked in hotels as well as homes and businesses.
What the job involves on each surface
Concrete and blockwork
Wide joints in concrete need the depth controlling carefully. Backing rod sized to the joint sets it.
Joints between dissimilar materials
Wherever two materials meet, they move differently. A flexible sealant bridges the two so neither cracks the other.

Outside joints around The Hythe
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you look after a building such as Kendall Church of England Primary School, larger buildings have long runs of movement joint that eventually need resealing. Letting a property close to Hythe station? Then outside joints that have cracked can let damp into a rental, so check them between lets. Homes close to Church of St Leonard at the Hythe include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move.

Honest limits
We’d rather tell you now than do work that will not last, so here’s what sealant can’t put right:
- Failed render or damaged cladding panels
- Walls that need new movement joints cut into them
- Movement that is more than a sealant joint can take
If you’re not sure, just call 0345 464 0079 or drop us an email and we’ll give you a straight answer before booking.
Surfaces we seal
- Render & cladding joints
- Copings & trims
- Concrete & block
- Façade panels
- Brickwork movement joints
- Joints between brick and frames
Looking after it afterwards
Looking after new joints is easy:
- Look over the joints every year, ideally after winter
- Make sure movement joints aren’t pointed over
- Get split or bare joints resealed while the damage is small
- Tell anyone working on the walls about the movement joints
Keep the joints clear of soil, plants and climbing growth. Anything that holds water against the joint wears it out sooner.
Water getting behind cladding or render can go unnoticed for a long time. When it finally shows inside, the joint may have been open for years, so it’s worth resealing at the first signs.
