About our gutter sealing in Marsh Gibbon
Failed sealant round a garage door frame lets rain blow in. We cut out the old sealant and reseal the frame using a sealant made for outdoor use. Common call-outs are for end caps that drip every time it rains and quick sealant fixes on gutters that didn’t last, across soffit joints, gutter end caps and garage door frames.
Outside joints can only be sealed when they’re dry, so work in Marsh Gibbon is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
A one-year guarantee comes as standard, so you’re covered after we have gone.

What happens on the day
Once we are on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take anything from an hour or two to a few hours. For a village or hamlet like Marsh Gibbon, 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.
- We find where the water is coming from and check the gutter is sound.
- The old sealant and dirt are cleaned out of the joint.
- We dry the joint so the new sealant can bond.
- We seal the joint with a sealant made for gutters.
- The gutter is checked and debris around the joints cleared.

How to look after the new joints
No joint lasts for ever, but care makes a real difference. A few tips:
- Look at the gutters while it’s raining
- Deal with a drip before winter
- Clean out the gutters once or twice a year
- Keep downpipes clear
Make sure downpipes aren’t blocked, so water can get away. A blocked pipe backs water up to the joints.
A drip from a gutter joint will not stop on its own. The same spot gets soaked every time it rains and that can cause damp inside.
What we are called out for in Marsh Gibbon
Leaves and moss hold water in the gutter. Standing water finds the weakest joint and leaks out.
These are the problems we are asked about most:
- Stop ends leaking at the end of a run
- Streaks down the brickwork from a leaking joint
- Water dripping where gutter sections meet
- Failed sealant on a garage door frame
Letting a property close to Bicester North station? Then a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside.
Questions to ask before you book
- How the joint is cleaned and prepared
- Whether the sealant suits the joint
- What the quote includes, VAT included or not
- Who does the work, and how experienced they are

Does someone need to be in?
We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.

Why act early in Marsh Gibbon
Leaving a leaking end cap can send water down the wall all winter. It’s a small job to put right compared with treating damp later. Older cottages and farmhouses around Marsh Gibbon can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
The cost depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. You’ll have a clear quote before any work starts.

Marsh Gibbon buildings and the weather
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Claydon House (about 4.8 miles east) are a reminder that the area around Marsh Gibbon has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
In the older streets around Church of St Mary, the joints between older walls, newer extensions and the roofline need a sealant that can move. Schools such as Marsh Gibbon CofE Primary School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing.
