Pitchcott External Mastic
Our applicators work in Pitchcott on sealing brickwork movement joints, render, cladding and façade joints. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.
- Joints with sealant missing in places
- Old sealant gone brittle and cracked
- Rigid filler in a joint that should flex
External mastic in Pitchcott
A movement joint is only as good as its depth. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, so it bonds to the two sides only and can stretch. If you have water getting into walls through failed joints and cracked joints where brick meets render or frames, we can help, whatever the surface.
Older homes in small places like Pitchcott may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points, and they need the right sealant at the right depth.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Pitchcott buildings and the weather
With historic houses such as Waddesdon Manor (about 3.7 miles south-west) nearby, there’s older building stock in the area around Pitchcott 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. 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.
Homes close to Church of St. Giles include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep. Managing a site like Whitchurch Combined School? Then its movement joints, gutters and trims need looking after like any other building’s.

Questions from Pitchcott
Is Pitchcott in your area for external mastic?
Yes, Pitchcott is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or send us an email and tell us what needs doing.
Will you come out to Pitchcott?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
What is a movement joint?
Walls move with heat, cold and moisture, so long walls have planned gaps to take that movement. It’s closed with backing rod and a flexible sealant.
Can you work on commercial sites?
Yes. We have worked for hotels, offices and other businesses.
How much does external mastic cost in Pitchcott?
Size, access and the old material all affect the cost. Ask us for a quote.
Where do you work from?
We’re based in Crawley, and we work across South East England, London and Scotland.
Can you seal over the old sealant?
No. The old sealant always comes out first.
Why do you put foam in the joint first?
That’s backing rod, a closed-cell foam. It stops the sealant going in too deep and bonding to three sides so it can flex with the joint.
Do you need external mastic in Pitchcott?
Buildings move more than people expect. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. The sealant in the movement joints takes that strain.
These are the problems we’re asked about most:
- Old sealant gone brittle and cracked
- Movement joints filled with mortar instead of sealant
- Moss and dirt in joints with no sealant left
- Failed sealant between panels on a façade
Letting a property close to Aylesbury Vale Parkway station? Then split movement joints are easy to miss on a rental until damp shows inside.

How the visit works
At the end, we look at the finished work together and tell you how long to leave it. The visit itself usually takes anything from a few hours to several days, depending on the building, depending on how much there is to do. Somewhere as small as Pitchcott, 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 will reach them.
- We cut out the failed sealant and rake out any dirt or growth.
- The joint faces are cleaned and primed where the sealant needs it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Preparing for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Mention any parking rules near the property
- Tell us about any previous sealing or DIY attempts

Related advice
Why it’s worth doing now in Pitchcott
Done well, a resealed joint is a neat, straight line that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner. Where a wall is exposed, as many are in small places like Pitchcott, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Combining jobs into one visit is usually more efficient than separate visits. You’ll get one clear quote for the whole job.

Different surfaces, different methods
Copings and trims
Coping and trim joints face rain and sun head on. We reseal them with an exterior sealant suited to the material.
Render joints
Water behind render can lead to blown patches. A sound joint keeps the render dry behind and helps it last.
