External mastic for homes and businesses in Penton Mewsey
Joints in render and cladding are easy to overlook until a damp patch appears. We look over the joints, agree the ones to renew and reseal with a flexible, weatherproof product in a colour to suit. If you are dealing with joints pointed up with cement by mistake and cracked joints where brick meets render or frames, we can put it right.
Older homes in small places like Penton Mewsey 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.
Each job carries a 12-month guarantee, large or small.

Related advice
Do you need external mastic in Penton Mewsey?
Some movement joints have been pointed up with mortar by mistake. The joint cannot move, so the wall cracks somewhere else instead.
The most common problems we see are:
- Sealant pulling away from one side of the joint
- Water getting into walls through failed joints
- Movement joints filled with mortar instead of sealant
- Old sealant gone brittle and cracked
Letting a property close to Andover station? Then outside joints that have cracked can let damp into a rental, so check them between lets.

Penton Mewsey buildings and the weather
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 Holy Trinity Church, older walls, gutters and the joints where extensions meet them need a flexible sealant. Schools such as Harrow Way Community School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Your questions about external mastic in Penton Mewsey
Is Penton Mewsey within the area you cover?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.

Yes, we work for letting agents and landlords. You can phone 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before we start.
Can you reach joints on upper floors?
That depends on how high the joints are and the ground below. Low-level joints are straightforward; for higher ones, send details and we’ll confirm the access.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
When will the joints need doing again?
It varies from wall to wall: joints on exposed walls or with a lot of movement age sooner. Check them each year and reseal when they split or harden. Every job carries our 12-month guarantee.
Can you quote for more than one area?
Yes, we can. Several rooms, windows or areas can go on one quote.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
Will there be a smell?
Some sealants have a smell while they cure. Opening a window helps.
Work for landlords, hotels and businesses
Letting agents and landlords in Penton Mewsey can book us as well as homeowners. Resealing between tenancies keeps a property looking cared for before the next move-in.
Mouldy or split sealant often shows up at the end of a tenancy. We can quote for more than one property at once.
What the job involves on each surface
Concrete and blockwork
Concrete and block walls shrink as they dry and move with temperature. We reseal their joints with backing rod and a flexible product.
Brickwork movement joints
Clay brickwork grows slightly over its life and moves with the weather. That movement goes into the joint, so its sealant has to stay flexible.

Looking after it afterwards
Simple care keeps the joints in good condition. Our advice:
- Keep high-pressure jets off the joints
- Don’t let climbing plants root in the sealant
- Leave the joints unpainted unless we have said otherwise
- Tell anyone working on the walls about the movement joints
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They should be kept open and resealed, not filled.
Act while the splits are small. At that stage it’s a simple cut out and reseal before water has had years to get in.
