Gutter sealing for homes and businesses in Addington
Our work covers gutter joints and end caps as well as fascias and soffits, along with roofline trims and garage door frames. It’s joint work, not replacing the gutter. We work on gutter end caps, uPVC fascias and gutter joints, and the jobs we see most are drips from gutter joints and end caps and failed sealant on a garage door frame.
Older homes in small places like Addington may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points.
A 12-month guarantee comes as standard, so you are not left on your own once the job is done.

Addington: your questions answered
Do you cover Addington for gutter sealing?
Yes. We work across London and the South East, and Addington is part of that. Just ring 0345 464 0079 or email us with a few details of the job, and we will give you a clear price.
Will you come out to Addington?
Yes. Addington is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you replace gutters or fascias?
No. We seal leaking joints and trims. A gutter installer or roofer deals with replacement.
Do I need to be at home?
It depends on the job. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
How long does the job take?
That depends on how much there is to do, but as a guide it takes an hour or two for a few joints, longer for a full run. We’ll tell you when we quote.
Can you do several jobs on one visit?
Yes, and it often makes sense. Doing several areas at once is usually more efficient, so mention them when you ask for a quote.
How long before the joint can be used?
It depends on the product and the temperature. Before we leave, we will tell you the cure time.
How the visit works
Most of a good job is in the preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. In total, it generally takes anything from an hour or two to a few hours. Somewhere like Addington needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.

Common problems we fix in Addington
Water spilling over a blocked gutter is often mistaken for a leak. If the downpipe is blocked, water has nowhere to go, which is why we look before we seal.
People normally contact us when they notice one of these:
- Stop ends leaking at the end of a run
- Internal damp traced to a gutter joint
- Old sealant on roofline trims that has split
- Leaking gutter joints and stop ends
If you look after a building such as Offham Primary School, its movement joints, gutters and trims need looking after like any other building’s.
Before booking anyone

When it is not the sealant
We will not take on work that won’t last, so these are the limits:

Aftercare tips
Good habits help new joints last longer. A few tips:
- Watch the wall under the gutters for staining
- Look at the gutters while it’s raining
- Clear leaves and moss from the gutters
- Make sure downpipes are not blocked
Keep the gutters clear of leaves and moss so water doesn’t sit on the joints. Water left in a gutter tests every joint.
Once roofline sealant splits, water can get behind it. Resealing early protects the boards.
Why it’s worth doing now in Addington
New gutters cost far more than a few resealed joints. Where the gutter is in good order and only a joint leaks a reseal is all it needs. If it has failed, we will tell you. Older cottages and farmhouses around Addington can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
What you pay reflects the work, not guesswork. That is why we ask about the job first and agree the price before starting.

What gutter sealing looks like in Addington
With historic houses such as Old Soar Manor (about 3.9 miles south-west) nearby, there’s older building stock in the area around Addington as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
In the older streets around Church of St Margaret, the joints between older walls, newer extensions and the roofline need a sealant that can move. Rented homes near West Malling station change hands often, and a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking.

Surface by surface
Gutter joints
Most gutter leaks start at a joint between sections. They’re cleaned out, dried and resealed.
Roofline trims
Roofline trims rely on sealant at their joints. When it splits, water can get behind.
