About our external mastic in Ecchinswell
Short cuts in external joints show up within a season or two. New sealant over old, joints packed with mortar and beads with no backing rarely last long. We take the old material out and do it properly. If you are dealing with moss and dirt in joints with no sealant left and gaps where render, brick and frames meet, we can put it right, on joints between brick and frames, brickwork movement joints and copings & trims alike.
Outside joints can only be sealed when they’re dry, so work in Ecchinswell is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
Each job carries a 12-month guarantee.

Can I do it myself?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Why act early in Ecchinswell
An open joint keeps letting water into the wall with every downpour. In cold weather, frost can damage wet brick and render near the open joint, so the damage spreads beyond the joint. Around Ecchinswell, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Leaving a failed joint normally makes the job bigger, not smaller. If you’re not sure whether it needs doing, ring 0345 464 0079 or send us an email and we will give you an honest view and a quote.

How we quote for external mastic
Jobs vary more than people expect. The main factors:
- The number of rooms or windows
- How much old sealant there is and how hard it is to remove
- Mould in or behind the old joints
- How much there is to do
The cost depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before we start, so you know where you stand.
What to tell us for a quote
Photos help, but a description is a good start. Try to tell us:
- The rough size of the job
- Pictures of the joints, sent by email
- Where the job is, and your postcode
- Any access issues, like height or stairs
Getting a quote is simple: let us know what needs doing and where and its rough size. A few photos by email make the job easier to understand.
How the visit works
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, do the work and tidy away. Most jobs take a few hours to a few days, depending on the length of joint and the access. In a small place like Ecchinswell, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
Before we arrive
- Plan for the work area to be out of bounds to pets and children
- Clear the area around the work
- Tell us about any water getting in

Ecchinswell buildings and the weather
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Highclere Castle (about 3.4 miles west) nearby, there’s older building stock in the area around Ecchinswell as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
If you live in an older home near Church of St Lawrence, the joints between older walls, newer extensions and the roofline need a sealant that can move. For landlords with property near Thatcham station, outside joints that have cracked can let damp into a rental, so check them between lets.

Looking after it afterwards
A little care helps the new joints last. Our advice:
- Deal with leaking gutters that soak the joints below
- Look over the joints every year, ideally after winter
- Check the sealant is paintable before painting near it
- Tell anyone working on the walls about the movement joints
Follow the cure time we give you before the joint is knocked or disturbed. Most exterior sealants skin fast but take longer to cure right through.
An open movement joint lets rain into the wall every time it pours. Over time it can mean damp inside, stained render or frost-damaged brick which cost more to put right than the joint.
FAQs for Ecchinswell
Do you work for landlords with property near Thatcham station?
Yes, we work for landlords and letting agents. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before work begins.
Is Ecchinswell within the area you cover?
Yes. Ecchinswell is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you remove the old sealant?
Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
How much does external mastic cost in Ecchinswell?
We don’t 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.
Do you use backing rod?
That’s backing rod, a closed-cell foam. It stops the sealant going in too deep and bonding to three sides, which would stop it stretching.
Where are you based?
We’re a Crawley-based firm. Our area covers South East England, London and Scotland.
Can you seal joints between render and window frames?
Yes. We cut out the old sealant, prepare both faces and reseal with a flexible exterior product. We pick a colour that works with both materials.
Can I add another job to the visit?
Yes, we can. More than one area can be quoted together.
What we are called out for in Ecchinswell
Joints sealed without backing rod, or far too deep, rarely last. Sealant bonded to three sides has nowhere to go and rips as the joint opens.
These are the problems we are asked about most:
- Sealant pulling away from one side of the joint
- Old sealant gone brittle and cracked
- Water getting into walls through failed joints
- Failed seals between different materials
Managing a site like Ecchinswell and Sydmonton Church of England Primary School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
