Gutter sealing in New Marston, done properly
Water dripping from a gutter joint can stain walls and soak the ground below. Resealing the joint is often all it needs, as long as the gutter is sound. If you have old gutter sealant that has let go and cracked sealant along roofline trims, we can put it right, on gutter end caps, garage door frames and soffit joints alike.
In and around New Marston, older properties sit alongside newer ones, each with its own outside joints. Older gutters and trims need their joints resealed; newer brick and render need their movement joints kept sound.
All our work is covered by a 12-month guarantee, wherever you are in Oxfordshire.

Different surfaces, different methods
Gutter joints
A gutter joint has to cope with movement and standing water. A dedicated gutter sealant suits them.
Roofline trims
Trim joints are cut out and resealed suited to the material.
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Make sure downpipes aren’t blocked
- Don’t lean ladders against the gutter itself
- Glance at the soffit joints now and then
- Keep the gutters clear of debris
Keep the gutters clear of leaves and moss so water does not sit on the joints. Water left in a gutter tests every joint.
If an end cap is dripping, deal with it before winter. Water down the wall all winter can cause damp.
Do you need gutter sealing in New Marston?
Overflowing gutters can look like leaking joints. A blocked downpipe makes water back up so we check the cause first.
Keep an eye out for any of the following:
- Damp patches inside below a leaking gutter
- Open joints in fascias and soffits
- Cracked sealant along roofline trims
- Old gutter sealant that has let go
For an older house near a landmark such as Saint Michael and All Angels, older walls, gutters and the joints where extensions meet them need a flexible sealant.

Should I try it myself first?
If you’ve already had a go yourself, that is fine. We cut it out and start again.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
Common questions in New Marston
Do you cover smaller places like New Marston?
Yes, New Marston is covered. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do you cover New Marston for gutter sealing?
Yes, New Marston is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or send us an email and let us know what needs doing.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Can I choose the sealant colour?
Yes. White, clear and grey are common, and other colours are available, and we agree the colour with you before any work starts.
What do you need from me for a quote?
A short description and the location, plus photos if you have them. We’ll ask anything else we need to know.
Can sealant stop a sagging gutter leaking?
Not for long. The movement opens the joint again so the gutter has to be refixed first.
I’m a tenant. Can you help?
Yes. Check with your landlord; we can send the quote to them too.
How much does gutter sealing cost in New Marston?

How the visit works
A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, carry out the job and tidy away. It usually takes anything from an hour or two to a few hours. Parking around New Marston is usually easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- First, we find the drip and check the gutter is not cracked or sagging.
- Old sealant and dirt are removed from the joint.
- The area is dried so the sealant can bond.
- An exterior or gutter sealant is applied to the joint.
- We check the run and clear any debris we find while we are there.
How to prepare
- Mention any sign-in or site rules at work premises
- Let us know about stairs, lifts or work at height
- Keep children and pets away from the work area

Outside joints around New Marston
With historic houses such as Holywell Manor (about 0.7 miles south-west) nearby, there’s older building stock in the area around New Marston as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you let a flat or house near Oxford station, a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside. For site and facilities teams at buildings such as St Michael's CofE Primary School, larger buildings have long runs of movement joint that eventually need resealing.
