What do you put in the joint?

Will sealant fix a dripping gutter joint?
In most cases, yes. If the gutter is sagging or cracked, sealing will not last and we’ll say so.

Some sealants have a smell while they cure, which fades as it sets. Ventilation helps.

Gutter sealing for homes and businesses in Catherington
We do not replace gutters, fascias or roofs. Sealant fixes joints and it can’t mend broken brackets, split sections or blocked downpipes. We work on uPVC fascias, gutter joints and garage door frames, and the jobs we see most are trim joints where the sealant has failed and water running down the wall below the gutter.
Somewhere as small as Catherington, homes and farm buildings often face open ground, so walls and rooflines take the full force of wind and rain. Joints on those walls need a sealant that moves with the building and stays in place.
All of our work is guaranteed for twelve months.

DIY sealant or a professional job?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
Catherington buildings and the weather
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 Catherington Church of England Infant School, its movement joints, gutters and trims need looking after like any other building’s. If you live in an older home near Church of All Saints, an extension built onto an older house moves differently, and the joint between them takes the strain.

Why act early in Catherington
You don’t need new fascias just because the joints have opened. Sealing the joints tidies them up if the boards are sound. In a small place like Catherington, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
The cost depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before any work starts.
Why choose Mr Mastic in Catherington
- We never seal over old sealant

When something else is needed
To be straight with you, some problems need a different trade:
- Blocked downpipes
- Fascias that need replacing
- Leaks from the roof rather than a joint
If you are not sure, just ring 0345 464 0079 or email us and we will give you a straight answer before booking.
What we seal
- Gutter end caps
- uPVC fascias
- Garage door frames
- Gutter joints
- Roofline trims
- Soffit joints
Looking after it afterwards
After the cure time, these simple habits help:
- Get a dropping gutter looked at quickly
- Clean out the gutters once or twice a year
- Rest ladders on the wall, not the gutter
- Deal with a drip before winter
Make sure downpipes aren’t blocked, so water can get away. A blocked pipe backs water up to the joints.
A leaking stop end is best sealed before the wet months. A winter of drips can lead to damp patches inside.

These are the problems we’re asked about most:
- End caps that drip every time it rains
- Trim joints where the sealant has failed
- Water dripping where gutter sections meet
- Old gutter sealant that has let go
For landlords with property near Rowlands Castle station, a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside.
