External mastic in Boxford, done properly
For buildings in Boxford, we reseal external joints of all kinds, from brick movement joints to cladding panels. Every joint gets the same careful preparation: clean, sound faces and a controlled depth. We work on façade panels, joints between brick and frames and render & cladding joints, and people most often call us about failed sealant between panels on a façade and plants rooting in failed movement joints.
In a village or hamlet like Boxford, older cottages and farm buildings often stand in the open, so walls and rooflines take the full force of wind and rain. Gutter joints and wall joints there need a sealant that can flex and stay put.
All of our work is guaranteed for twelve months.

Signs you need external mastic in Boxford
Every building moves. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. All of that ends up in the joint sealant.
People usually contact us when they notice one of these:
- Rigid filler in a joint that should flex
- Moss and dirt in joints with no sealant left
- Failed seals between different materials
- Failed sealant between panels on a façade
In the older streets around Parish Church of St Andrew, older walls, gutters and the joints where extensions meet them need a flexible sealant.

What happens on the day
Before we leave, we go over the finished joints with you. The work normally takes a few hours to a few days, depending on the length of joint and the access, depending on how much there is to do. Somewhere like Boxford needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We start by walking round the building and agreeing the joints and the access.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires 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
- Mention any leaks or damp you’ve noticed
- Let us know about parking restrictions
- Tell us about access, such as stairs, a lift or high-level joints

Advice
Can I do it myself?
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly.
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, and the work is guaranteed for a year.
Looking after it afterwards
To keep the joints looking good and working properly:
- Ask before painting over external sealant
- Wash walls gently around the sealant
- Make sure movement joints are not pointed over
- Check external joints each spring
Give the sealant the cure time we tell you before anything rubs against it. The surface skins over quickly, but full cure takes longer.
Once a joint can’t move, the wall finds another way, generally as cracking in the brickwork or render nearby. Catch it early and you reduce the risk.
When it isn’t the sealant
We’d rather tell you now than do work that won’t last, so these are the limits:
- Render that is blown, hollow or coming away
- Cracking across the wall rather than at a joint
- Movement that’s more than a sealant joint can take
If you are not sure, just ring 0345 464 0079 or send us an email and we’ll give you a straight answer.

When is the sealant fully cured?
Different products cure at different speeds, so please follow the time we give you when we finish.
Will you leave a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Can I add another job to the visit?
Yes. Several rooms, windows or areas can go on one quote.
How long does the job take?
Most jobs take anything from a few hours to several days, depending on the building, including preparation and clearing up. Your quote will say how long we expect yours to take.
What is a movement joint?
A vertical gap in a long brick wall is normally a movement joint. It lets the bricks expand without cracking.
How much does external mastic cost in Boxford?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we’ll talk you through it.

What happens if it’s left?
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. A stiffer product can damage the joint edge as it fails. In a small place like Boxford, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Doing several joints on one visit is generally more efficient than separate visits. You’ll get one clear quote for the whole job.

Walls and rooflines in Boxford
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Benham Park (about 2.5 miles south) are a reminder that the area around Boxford has older buildings as well as new. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
Rented homes near Kintbury station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets.
