About our window mastic in Rodmell
Behind a thin line of old mastic there’s sometimes a deep void. Filling it with sealant alone leaves a joint that cannot move properly, so we fit backing rod to set the right depth. The sealant then grips the two sides it should. We work on window sills, timber windows & doors and composite doors, and common reasons people get in touch are rain getting in at the frame or under the sill and hard, cracked sealant around windows.
In a village or hamlet like Rodmell, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Windows and doors in Rodmell
With historic houses such as Monk's House (about 0.4 miles north-east) nearby, there’s older building stock in the area around Rodmell as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you look after a building such as Priory School, larger buildings have plenty of frames, and the mastic around each one ages. Rented homes near Southease station change hands often, and cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

What else we do in Rodmell
Leave it or put it right?
Once mastic fails, rain can get between the frame and the wall. Left long enough, it can stain inside walls, spoil plaster and rot wooden frames. Resealing now is a small job by comparison. In a small place like Rodmell, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re not sure whether it needs doing, call 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.
Why choose Mr Mastic in Rodmell
- 20+ years of sealant experience
- Domestic, commercial and hotel work
- Old sealant always removed completely
- Neat joints and a tidy finish
See our cost guide or our reviews.
Can I do it myself?
If you are 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 fails, we can still redo it.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
What we are called out for in Rodmell
Older frames were often sealed with products that set hard. Once it has hardened, the frame’s movement tears it from the wall, leaving a hairline gap down one side.
The most common problems we see are:
- Gaps where the sill meets the wall
- White mastic on grey or black frames
- Water coming in at the bottom corners of a door
- Mastic that has split away from the wall
Homes close to St Peter's Church include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

What sealant work cannot fix
In fairness, some problems need a different trade:
- Faulty window hardware
- A failed sealed unit that has misted up
- A frame that has rotted at the joint

What happens on the day
Before we leave, we go over the finished joints with you. The work normally takes a morning for a couple of windows and a door, depending on how much there is to do. In a small place like Rodmell, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we go round the frames with you and agree the list.
- We remove the old mastic and clean the frame edge and wall.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
How to prepare
- Clear items away from the joints we’re working on
- Mention any parking rules near the property
- Mention any tricky access

Different surfaces, different methods
Patio & French doors
Not every patio door leak is a mastic problem: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We check before we reseal.
Aluminium frames
Bi-fold and sliding aluminium doors have long frame joints, and the bottom joint sees the most water. We prepare and reseal every joint, backing the deep ones.
