External mastic in Ugley
Failed sealant is cut out, the depth set with closed-cell backing rod, and the joint resealed with a low-modulus sealant made for outside. We pick a colour that sits well with the wall so the joint does not stand out. We work on brickwork movement joints, façade panels and copings & trims, and people most often call us about moss and dirt in joints with no sealant left and damp patches traced to an open external joint.
Older homes in small places like Ugley may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water usually gets in, and they need the right sealant at the right depth.
Big or small, it’s backed by our one-year guarantee.

How to look after the new joints
So the new joints stay in good condition:
- Leave the joints unpainted unless we have said otherwise
- Show decorators and builders where the movement joints are
- Keep high-pressure jets off the joints
- Keep soil, plants and ivy away from the joints
Keep the joints clear of soil, plants and climbing growth. Anything that holds water against the joint wears it out sooner.
Once a joint can’t move, the wall finds another way, often as cracks near the joint. Resealing it early helps prevent that.
Common problems we fix in Ugley
Sometimes a movement joint was filled with mortar or a rigid filler. The joint cannot move, so the wall cracks somewhere else instead.
Signs it’s time to call us include:
- Cracked joints where brick meets render or frames
- Water getting into walls through failed joints
- Joints with sealant missing in places
- Joints pointed up with cement by mistake
Letting a property close to Elsenham station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Should I try it myself first?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
A DIY attempt does not rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
What happens if it’s left?
Water gets in through a failed movement joint and can run behind render or cladding. Dealing with it early keeps the repair to the joint, rather than the wall around it. Around Ugley, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote.

Your questions about external mastic in Ugley
Do you work for landlords with property near Elsenham station?
Yes, we work for letting agents and landlords. Just ring 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear quote.
Is Ugley within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you do several jobs on one visit?
Yes, and it often makes sense. Doing several areas at once is normally more efficient, so mention them when you ask for a quote.
What does external mastic cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
When is the sealant fully cured?
That depends on the sealant used, so please follow the time we give you.
Will it make a mess?
Tidy work is part of the job. Nearby surfaces are protected.
What do you put in the joint?
Products from Arbo and Everbuild, among others, picked for each joint. We will tell you what we’re using and why.
How it works
At the end, we look at the finished work together and tell you how long to leave it. The visit itself generally takes a few hours to a few days, depending on the length of joint and the access, depending on the size of the job. Somewhere as small as Ugley, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
Before we arrive
- Move anything stored near the joints
- Tell us about any previous sealing or DIY attempts
- Mention any tricky access

What the job involves on each surface
Brickwork movement joints
Brick walls have vertical movement joints to absorb expansion. We reseal them with a low-modulus sealant over backing rod in a colour to suit the brick.
Cladding and façade panels
Where a cladding system has its own specified sealant, we follow it or an approved alternative. Tell us what the building has when you get in touch.

How we quote for external mastic
Your quote is based on your job. We look at:
- The type of sealant required
- Whether the work is at height
- The size of the job

A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
Helping us quote
You do not need to know the technical terms. Just tell us:
- What the problem is, such as mould, gaps, leaks or cracking
- How we’d reach the joints

Ugley buildings and the weather
Historic houses like Horham Hall (about 4.6 miles east) are a reminder that the area around Ugley has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
In the older streets around Church of St Peter, an extension built onto an older house moves differently, and the joint between them takes the strain.
