Gutter sealing in Middle Assendon, done properly
We seal leaking gutter joints, end caps, fascia and soffit joints plus roofline trims and garage door frames. It’s joint work, not replacing the gutter. We work on uPVC fascias, gutter joints and gutter end caps, and common reasons people get in touch are damp on an inside wall under a dripping gutter and cracked sealant along roofline trims.
Around Middle Assendon, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points, and they need the right sealant at the right depth.
Your job is guaranteed for a year, as with all our work.

Leave it or put it right?
Replacing guttering is a much bigger job than sealing joints. Where the gutter is in good order and only a joint leaks, resealing is the sensible fix. If it has failed, we’ll tell you. Where a wall is exposed, as many are in small places like Middle Assendon, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

Middle Assendon questions
Can you do gutter sealing in Middle Assendon?
Yes. We work across London and the South East, and Middle Assendon is part of that. You can phone 0345 464 0079 or email us and tell us what needs doing, and we will send you a clear quote.
Can you help a landlord with a rental near Henley-On-Thames station?
Yes. We work for letting agents and landlords as well as homeowners, and several properties can be quoted together. Just phone 0345 464 0079 or email us with the address and what needs doing, and we will give you a clear quote.
Should I try DIY first?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Are you ARBOMaster approved?
Yes. We’re approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
Can I choose the sealant colour?
Most of the time, yes. We will tell you which colours the right product comes in and agree one before work begins.
Will sealant fix a dripping gutter joint?
In many cases, yes. Cleaning, drying and resealing the joint usually works. If the section is split or warped, it needs replacing.
Can you reach high gutters?
It depends on the access. Let us know the height and the ground below and we will confirm what’s needed.
Are you insured?
Yes, we’re fully insured for every job we do.
How to look after the new joints
A little care helps the new joints last. We recommend:
- Look along the fascias for open joints
- Deal with a drip before winter
- Check that water runs out of the downpipes
- Do not leave a sagging gutter
Keep the gutters clear of leaves and moss, so water drains away past the joints. Water left in a gutter tests every joint.
Early sealing limits how much water hits the wall. We’ll let you know if the gutter needs more than sealant.
What affects the quote in Middle Assendon
Every job gets its own quote. These are the things that affect it:
- Any working-time requirements on site
- The type of sealant required
- The number and length of the joints
- Whether old sealant or filler has to be cut out
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
Helping us quote
Photos by email are helpful but not essential. Try to tell us:
- How many joints, rooms or windows are involved
- Photos by email, if that is easy
- What the problem is, such as mould, gaps, leaks or cracking
- How we’d reach the joints

Should I try it myself first?
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
Work for landlords, hotels and businesses
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we will give you a quote.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.

What else we do in Middle Assendon
Surface by surface
Roofline trims
Roofline trims rely on sealant at their joints. Split sealant lets water in.
Gutter end caps
End caps take the pressure of water running along the gutter. When their seal fails, they drip.
The process
A visit follows a simple pattern: we check the joints, protect the area around them, carry out the job and clear up. It generally takes anything from an hour or two to a few hours. For a village or hamlet like Middle Assendon, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We look at where the water is coming from and check the gutter isn’t broken or sagging.
- Old sealant and dirt are removed from the joint.
- The joint is dried, because sealant will not bond to a wet surface.
- An exterior or gutter sealant is applied to the joint.
- The run is checked and any debris near the joints is cleared.
Getting ready for the visit
- Let us know about earlier repairs to the joints
- Tell us if parking is tricky
- Mention any leaks or damp you’ve noticed

Outside joints around Middle Assendon
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Greys Court (about 1.8 miles south-west) are a reminder that the area around Middle Assendon has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.
Homes close to Church of St James include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move. If you let a flat or house near Henley-On-Thames station, a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside.
