Can I do it myself?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
About our gutter sealing in Wytham
We do not replace gutters, fascias or roofs. Sealant fixes joints; it will not fix a broken bracket, a cracked section or a blocked downpipe. Typical jobs include rain getting in around a garage door and wet patches on the wall under a gutter joint, across garage door frames, uPVC fascias and gutter end caps.
Outside joints can only be sealed when they’re dry, so work in Wytham is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
There’s a 12-month guarantee on every job, whatever its size.

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Check the gutters during heavy rain
- Don’t leave a sagging gutter
- Check that water runs out of the downpipes
- Keep the gutters clear of debris
A sagging gutter needs its brackets checked. Movement will pull the joints open again.
A leaking garage frame lets water reach stored items. A reseal sorts it.
Different surfaces, different methods
uPVC fascias
Open fascia joints look untidy and can let water in. Sealing them closes the gap.
Gutter end caps
We seal end caps from the inside where we can reach, after cleaning and drying.
Wytham buildings and the weather
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Holywell Manor (about 3.1 miles south-east) nearby, there’s older building stock in the area around Wytham as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
If you let a flat or house near Oxford Parkway station, leaking gutter joints on a rental are best caught before they stain the walls. In the older streets around Church of All Saints, old and new materials meet at the roofline and walls, which is where sealant earns its keep. For site and facilities teams at buildings such as Oxford Academy, larger buildings have long runs of movement joint that eventually need resealing.

What we do, step by step
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours, depending on the number of joints and the access. For a village or hamlet like Wytham, 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.
- The joint is dried before sealing.
- A gutter sealant is applied to the joint.
- We check the run and clear debris near the joints.
Getting ready for the visit
- Mention any sign-in or site rules at work premises
- Keep pets and children clear of the area while we work
- Tell us about any water getting in

Related advice
What happens if it’s left?
Water from a leaking joint hits the same spot every time. Left, it can stain walls and lead to damp, so it’s worth sealing early. In a small place like Wytham, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.

Will sealant fix a dripping gutter joint?

Sealant will not hold a sagging gutter. The gutter needs refixing by a gutter installer.

Is there any odour?
That depends on the sealant. Some smell for a while, some hardly at all.
