External mastic for homes and businesses in South Earlswood
A movement joint is a deliberate break that lets a wall expand and contract. The sealant in it has to stretch and squeeze for years, and when it fails, the wall takes the strain and water finds a way in. We are often asked to deal with failed seals between different materials and weeds or debris growing in open joints, on concrete & block, façade panels and joints between brick and frames.
External sealant needs dry, clean surfaces, so work around South Earlswood is planned for dry weather. Tell us about access to all sides of the building, including outbuildings and garages.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

How the job changes by surface
Render joints
Cracks along render joints let water in behind the coat. Resealing the joints early keeps water out and protects the render itself.
Joints between dissimilar materials
Where a frame or panel meets masonry, water often finds a way in. The old joint is removed and a sealant that bonds to both sides goes in.
How to look after the new joints
Good habits help new joints last longer. A few tips:
- Keep high-pressure jets off the joints
- Ask before painting over external sealant
- Fix overflowing gutters above sealed joints
- Never let anyone fill a movement joint with mortar
Do not let soil, plants or ivy build up against the new joints. Damp material against the sealant shortens its life.
Water getting behind cladding or render can go unnoticed for a long time. By the time there’s a damp patch, the damage can be well established.
Work for landlords, hotels and businesses
Housing providers, facilities teams and property managers book us too. Several sites can go on one quote.
From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
What affects the quote in South Earlswood
We don’t publish a price list, because jobs vary so much. The quote depends on:
- How many rooms, windows or areas are involved
- The product the joint needs
- The amount of work
- When we can work, for business premises
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.
Helping us quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- Whether it’s a home or a business
- Access, such as stairs, a lift or height
- The problem you’ve noticed
- How many joints, rooms or windows are involved
For a quote, call 0345 464 0079 or drop us an email with the location and a short description of the problem. We will give you a clear price before any work starts.
When to call us in South Earlswood
Buildings move more than people expect. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. The sealant in the movement joints takes that strain.
Common reasons people contact us include:
- Brick movement joints where the sealant has split
- Sealant that has lost its bond to the brick or render
- Rain getting behind render or cladding at a joint
- Old sealant gone brittle and cracked
Schools such as Salfords Primary School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing.
What to look for in a quote
- Is the old sealant removed completely?
- What the cure time is
- What insurance they hold
- What happens if they find a problem under the old sealant
Outside joints around South Earlswood
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Homes close to Christ the King include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant. For landlords with property near Earlswood (Surrey) station, split movement joints are easy to miss on a rental until damp shows inside.

What happens if it’s left?
A failed movement joint lets water into the wall. Dealing with it early keeps the repair to the joint, rather than the wall around it. Where a wall is exposed, as many are in small places like South Earlswood, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.

What we do, step by step
There’s no need to move everything out, only the area right around the joints. Everything nearby is protected, and the work takes a few hours to a few days, depending on the length of joint and the access in most cases. Somewhere as small as South Earlswood, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by checking each joint, agreeing the ones to redo and how we’ll reach them.
- The old mastic and anything lodged in the joint is removed.
- The joint faces are cleaned and primed where the sealant needs it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- Where the joints are inside, avoid wetting them before we arrive
- Plan for the work area to be out of bounds to pets and children
