What the job involves on each surface
Joints between dissimilar materials
Each side of the joint may need its own preparation. Both surfaces are cleaned and primed as the product requires.
Concrete and blockwork
Concrete and block walls shrink as they dry and move with temperature. Their movement joints are sealed over backing rod with a flexible sealant.
External mastic in Earlstone Common, done properly
Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible sealant bridges the two. We’re often asked to deal with brick movement joints where the sealant has split and cracked joints where brick meets render or frames, on render & cladding joints, copings & trims and concrete & block.
Outside joints can only be sealed when they’re dry, so work in Earlstone Common is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
Each job carries a 12-month guarantee, large or small.

FAQs for Earlstone Common
Do you cover Earlstone Common for external mastic?
Yes, Earlstone Common is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or drop us an email and tell us what needs doing.
Do you cover smaller places like Earlstone Common?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can I add another job to the visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
What is a movement joint?
Brickwork, render and cladding all move a little, so long walls have planned gaps to take that movement. The gap is sealed with a flexible sealant over backing rod.
Can tenants book the work?
Yes, though it’s best to check with your landlord first. Many landlords are glad to have it sorted.
What colours does the sealant come in?
The aim is a neat, even joint in a colour that suits the wall. We’ll talk through colour options before we start, matched as closely as the range allows.
Will there be a smell?
That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Are you ARBOMaster approved?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Can I do it myself?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.

Walls and rooflines in Earlstone Common
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Highclere Castle (about 2.6 miles south-west) are a reminder that the area around Earlstone Common 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 Newbury station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets. For an older house near a landmark such as Church of the Ascension, older walls, gutters and the joints where extensions meet them need a flexible sealant. For site and facilities teams at buildings such as The Clere School, its movement joints, gutters and trims need looking after like any other building’s.

What affects the cost of external mastic
Your quote is based on your job. We look at:
- Working hours on commercial sites
- The product the joint needs
- Mould in or behind the old joints
- How many rooms, windows or areas are involved
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you’re not sure whether it needs doing, phone 0345 464 0079 or drop us an email and we will give you an honest view and a quote.
Helping us quote
Before you ask for a quote, have a think about:
- Whether it’s a home or a business
- Where the job is, and your postcode
- If someone has resealed it before
- Access, such as stairs, a lift or height
Getting a quote is simple: let us know what needs doing and where and its rough size. A few photos by email make the job easier to understand.
Aftercare tips
Simple care keeps the joints in good condition. We recommend:
- Deal with leaking gutters that soak the joints below
- Keep movement joints as flexible joints, not mortar
- Ask before painting over external sealant
- Clear growth from the base of walls and joints
Have a quick look at the joints each spring. Splits, gaps at the edges or plants in the joint are early warning signs.
Leaks behind façade panels and render often go unseen. By the time there’s a damp patch, the damage can be well established so early resealing is worth it.
