How do I get a quote for external mastic in Souldern?
It depends on the job, so we quote each one individually. To get one, call 0345 464 0079 or drop us an email with a short description of the job.
How do you reach high-level joints?
It depends on the building. Where joints can be reached safely, we’ll do them. Give us some details and we’ll confirm the access.
Is it OK to fill a movement joint with cement?
No. Rigid materials can’t move with the wall, so the joint stops doing its job. Where a joint has been mortared, it can often be raked out and sealed properly.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned before resealing.
Will you leave a mess?
No. The area is protected while we work and cleaned up afterwards.
When will the joints need doing again?
It depends on the exposure, the movement and the product. Sealant is a maintenance item, so check the joints once a year and renew it when it starts to fail.
External mastic in Souldern, done properly
We’re ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Porous or awkward surfaces are primed where the sealant needs it and we use one wherever it does. If you have hard, crazed mastic that has stopped moving and failed seals between different materials, we can help, whatever the surface.
External sealant needs dry, clean surfaces, so work around Souldern is planned for dry weather. Tell us about access to all sides of the building, including outbuildings and garages.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

Why act early in Souldern
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. Too stiff a sealant can pull at the edges and break them. Where a wall is exposed, as many are in small places like Souldern, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Call for a quick quote and we will explain what it covers.

- Failed render or damaged cladding panels

What affects the quote in Souldern
The quote reflects the job in front of us. We look at:
- Which sealant suits the joint
- When we can work, for business premises
- How much there is to do
- How much old sealant there is and how hard it is to remove
Leaving a failed joint generally makes the job bigger, not smaller. If you are not sure whether it needs doing, ring 0345 464 0079 or send us an email for an honest opinion and a quote.
Asking for a quote
There’s no need for technical detail. It helps if you can tell us:
- Pictures of the joints, sent by email
- Whether it’s a home or a business
- Any previous sealing or DIY work
- Where the job is, and your postcode
Call for a quick quote, or send an email if you’d rather. Tell us about the joints that need doing and we will talk you through the work.
For landlords and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.
We regularly work with letting and managing agents. Tell us the address, the job and how access works and we’ll quote.
DIY versus a professional finish
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Souldern buildings and the weather
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For landlords with property near Kings Sutton station, outside joints that have cracked can let damp into a rental, so check them between lets. If you live in an older home near Church of the Annunciation to the Blessed Virgin Mary, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Surface by surface
Joints between dissimilar materials
Where a frame or panel meets masonry, water often finds a way in. We cut out the old sealant and reseal with a product suited to both surfaces.
Brickwork movement joints
Clay brickwork grows slightly over its life and moves with the weather. The movement joint takes that up, so its sealant has to stay flexible.
