What happens if it’s left?
Running new sealant over the old bead rarely lasts. New sealant does not bond well to old, weathered sealant, so we always take the old sealant out. In a small place like Ascott d'Oyley, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Combining jobs into one visit generally makes better use of the time than several visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.

About our external mastic in Ascott d'Oyley
Joints in render and cladding are easy to overlook until a damp patch appears. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant in a colour to suit. Typical jobs include weeds or debris growing in open joints and joints where the bead has come unstuck, on concrete & block, brickwork movement joints and render & cladding joints.
Outside joints can only be sealed when they’re dry, so work in Ascott d'Oyley is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
All of our work is guaranteed for twelve months.

When something else is needed
Some problems need a builder, plumber or other trade rather than us:
- Movement that is more than a sealant joint can take
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Cracking across the wall rather than at a joint
Not sure which it is? You can call 0345 464 0079 or send us an email and we will tell you honestly before you book.
Joints and surfaces we work on
- Render & cladding joints
- Façade panels
- Concrete & block
- Copings & trims
- Brickwork movement joints
- Joints between brick and frames
Aftercare tips
Simple care keeps the joints in good condition. We recommend:
- Wash walls gently around the sealant
- Keep soil, plants and ivy away from the joints
- Walk round the building once a year and look at the joints
- Leave the joints unpainted unless we’ve said otherwise
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. When it finally shows inside, the joint may have been open for years.
Ascott d'Oyley buildings and the weather
With historic houses such as Minster Lovell Hall (about 4.3 miles south) nearby, there’s older building stock in the area around Ascott d'Oyley as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Homes close to Church of the Holy Trinity include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move.

What we do, step by step
Before we leave, we go over the finished joints with you and tell you how long to leave it. The visit itself usually takes a few hours for a handful of joints, longer for a whole elevation, depending on the amount of work. For a village or hamlet like Ascott d'Oyley, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First we look over the joints with you, agree which to renew and talk through access.
- 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.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
How to prepare
- Tell us if parking is tricky
- For indoor joints, keep the area dry beforehand if you can
- Mention any tricky access

Should I try it myself first?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Signs you need external mastic in Ascott d'Oyley
Joints sealed without backing rod, or far too deep, rarely last. If the sealant sticks to the back as well as the sides, it cannot stretch and tears as soon as the joint widens.
The most common problems we see are:
- Leaking joints around cladding and façade panels
- Rigid filler in a joint that should flex
- Hard, crazed mastic that has stopped moving
- Rain getting behind render or cladding at a joint
If you let a flat or house near Ascott-Under-Wychwood station, split movement joints are easy to miss on a rental until damp shows inside.

Is the work guaranteed?
Yes. Every job comes with a 12-month guarantee.
Can I do it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
Do you seal joints where cladding meets other materials?
Yes. The old joint is removed, both surfaces cleaned and primed where needed, and a flexible sealant applied. We pick a colour that works with both materials.
Is it OK to fill a movement joint with cement?
No, not if it’s a movement joint. Filling it with mortar defeats its purpose, and the wall may crack nearby. A flexible sealant is the right fill.
How often do external joints need resealing?
It varies with how exposed the wall is and how much the joint moves. Look for splits, hardening or edges coming away, and reseal at that point.
Do you do commercial work?
Yes. We have worked for hotels, offices and other businesses and we’re fully insured.
