External & façade joints in Woodcote, Oxfordshire
Professional external mastic in and around Woodcote, with old sealant always removed completely.
- Rigid filler in a joint that should flex
- Moss and dirt in joints with no sealant left
- Rain getting behind render or cladding at a joint
How the visit works
Before we leave, we go over the finished joints with you and explain the cure time. The visit itself generally 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. A visit to Woodcote is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- 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.
Getting ready for the visit
- Let us know about parking restrictions
- Mention if the joints have been sealed before
- Keep children and pets away from the work area

External mastic for homes and businesses in Woodcote
Movement joints let brickwork, render and cladding expand and shrink without cracking. The sealant in it has to stretch and squeeze for years, so once it splits or hardens, the joint stops working and water gets in. We work on concrete & block, brickwork movement joints and copings & trims, and people most often call us about rigid filler in a joint that should flex and rain getting behind render or cladding at a joint.
Around Woodcote, garages, outbuildings and extensions all add to the joints on the outside of a home. Leaks normally start at a gutter end, a garage door frame or where an extension meets the house.

Woodcote buildings and the weather
With historic houses such as Basildon Park (about 3.1 miles south-west) nearby, there’s older building stock in the area around Woodcote 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. 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.
Letting a property close to Goring & Streatley station? Then outside joints that have cracked can let damp into a rental, so check them between lets. Managing a site like Woodcote Primary School? Then its movement joints, gutters and trims need looking after like any other building’s.

Can I do it myself?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

Woodcote: your questions answered
Do you cover Woodcote for external mastic?
Yes, Woodcote is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or email us and let us know what needs doing.
Can you help a landlord with a rental near Goring & Streatley station?
Yes, rental work is part of what we do. Just call 0345 464 0079 or email us and tell us about the property, and we will send you a clear quote.
Can you seal joints between two different materials?
Yes. Different materials move at different rates, so the joint between them must be flexible. We choose one that suits both surfaces.
How much does external mastic cost in Woodcote?
It depends on the job, so we quote each one individually. To get one, call 0345 464 0079 or send us an email with a short description of the job.
Will the old sealant be removed?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Is the work guaranteed?
Yes. Each job is guaranteed for twelve months.
Why do you put foam in the joint first?
Backing rod goes into deeper joints as a matter of course. It controls the depth and stops the sealant bonding to the back so the bead can stretch.
Do you work for hotels and businesses?
Yes. Hotels, offices and other businesses use us and we are fully insured.
Surface by surface
Cladding and façade panels
Metal and composite panels move a lot with temperature, so the joints work hard every day. We choose the product to suit.
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.
Work for landlords, hotels and businesses
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. Several properties can go on one quote.
How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Point out the joints to other trades
- Wash walls gently around the sealant
- Deal with leaking gutters that soak the joints below
- Get split or bare joints resealed while the damage is small
Keep the joints clear of soil, plants and climbing growth. Anything that holds water against the joint wears it out sooner.
Act while the splits are small. Then it’s a straightforward cut-out and reseal with no damage behind it to deal with.
Signs you need external mastic in Woodcote
Sometimes a movement joint was filled with mortar or a rigid filler, often by someone who didn’t know what it was for. The joint can’t move, so the wall cracks somewhere else instead.
It’s worth asking for a quote if you see:
- Cracked joints where brick meets render or frames
- Panel joints letting water in
- Sealant that has lost its bond to the brick or render
- Damp patches traced to an open external joint
For an older house near a landmark such as Church of St Leonard, an extension built onto an older house moves differently, and the joint between them takes the strain.

Why deal with it now?
Water gets in through a failed movement joint and can run behind render or cladding. Resealing early keeps the job to the joint itself, rather than the wall around it. In a smaller place like Woodcote, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
