What affects the quote in Medmenham
The quote reflects the job in front of us. We take into account:
- The number of rooms or windows
- Working hours on commercial sites
- Access and height
- Which sealant suits the joint
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.

External mastic in Medmenham, done properly
Getting the depth right is half the job. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, so it bonds to the two sides only and can stretch. If you are dealing with cracked joints where brick meets render or frames and moss and dirt in joints with no sealant left, we can help, on concrete & block, copings & trims and brickwork movement joints alike.
Somewhere as small as Medmenham, homes and farm buildings often face open ground, where walls and rooflines take the weather head on. Gutter joints and wall joints there need a sealant that can flex and stay put.
You are covered for a year from the day we finish. If there’s a problem with it, please call 0345 464 0079 or send us an email.

Honest limits
We won’t take on work that won’t last, so these are the limits:
- Walls that need new movement joints cut into them
- Movement that’s more than a sealant joint can take
- Loose or hollow render, which needs re-rendering
Not sure which it is? You can phone 0345 464 0079 or email us and we’ll tell you honestly.
Surfaces we seal
- Concrete & block
- Brickwork movement joints
- Façade panels
- Joints between brick and frames
- Copings & trims
- Render & cladding joints
Looking after it afterwards
To keep the joints looking good and working properly:
- Fix overflowing gutters above sealed joints
- Wash walls gently around the sealant
- Keep movement joints as flexible joints, not mortar
- Check the sealant is paintable before painting near it
Don’t paint over the new sealant unless we’ve said the product is paintable. Many exterior sealants aren’t designed to be painted.
A joint that has stopped moving pushes the movement elsewhere, often as cracks near the joint. Catch it early and you reduce the risk.
Do you need external mastic in Medmenham?
If plants are growing out of a joint, the sealant has usually failed or was never there. Roots and dirt hold water against the wall and make things worse.
Any of these means the joints need attention:
- Rain getting behind render or cladding at a joint
- Joints where the bead has come unstuck
- Old sealant gone brittle and cracked
- Gaps where render, brick and frames meet
Letting a property close to Henley-On-Thames station? Then outside joints that have cracked can let damp into a rental, so check them between lets.

The process
Good joint work is mostly preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. In total, it generally takes a few hours for a handful of joints, longer for a whole elevation. Somewhere as small as Medmenham, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
Before we arrive
- For indoor joints, keep the area dry beforehand if you can
- Keep pets and children clear of the area while we work
- Mention any sign-in or site rules at work premises

Advice
External mastic in Medmenham: local notes
With historic houses such as Harleyford Manor (about 1.3 miles east) nearby, there’s older building stock in the area around Medmenham as well as newer homes. In older buildings, 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, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For an older house near a landmark such as Church of St Peter and St Paul, the joints between older walls, newer extensions and the roofline need a sealant that can move. Managing a site like Danesfield School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

DIY sealant or a professional job?
What a professional job adds is preparation and the right 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.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.

Is Medmenham within the area you cover?
Yes. Medmenham is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.

Do the sealants smell?
Possibly a little. It fades as the sealant cures.
Can you seal joints between two different materials?
Yes. Joints between dissimilar materials are a big part of external work. The sealant is chosen to bond to both sides, primed where needed.
How do you reach high-level joints?
That depends on how high the joints are and the ground below. Ground-floor joints are simple; for higher ones, send details and we will confirm the access.
Is the work guaranteed?
Yes: twelve months. If there’s a problem with our work in that time, tell us and we will put it right.
Do I have to be there?
If the work is inside, we need someone to let us in. Once we’ve agreed the job, you do not need to watch us work.
Will you leave a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
