What we do, step by step
There isn’t much for you to do on the day. Point us to the joints and we’ll get on with it. The job generally takes an hour or two for a few joints, longer for a full run. In a small place like South Darenth, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
- We seal the joint with a sealant made for gutters.
- We check the run and clear debris near the joints.
How to prepare
- Keep pets and children clear of the area while we work
- Move anything stored near the joints
- Try not to wet indoor joints just before the visit

Gutter sealing in South Darenth
We don’t replace gutters, fascias or roofs. What sealant does is close joints and it cannot mend broken brackets, split sections or blocked downpipes. Common call-outs are for damp on an inside wall under a dripping gutter and garage door frames letting rain in, across uPVC fascias, gutter end caps and garage door frames.
Around South Darenth, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points.
Each job carries a 12-month guarantee.

What we’re called out for in South Darenth
Debris in the gutter keeps water sitting at the joints. Water that cannot drain works its way through a weak joint and drips through.
Look out for these signs:
- Dripping gutter ends
- Internal damp traced to a gutter joint
- Fascia boards with gaps between them
- Water running down the wall below the gutter
Managing a site like Horton Kirby Church of England Primary School? Then its movement joints, gutters and trims need looking after like any other building’s.

Different surfaces, different methods
Gutter joints
When a joint drips, the gutter is often still sound. Sealing the joint often stops it.
uPVC fascias
We seal fascia joints, not replace the boards. If boards are damaged, we’ll tell you.
Why it’s worth doing now in South Darenth
A dripping gutter joint keeps wetting the same patch of wall. Left, it can stain walls and lead to damp, so it’s worth sealing early. Around South Darenth, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

Should I try it myself first?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
What sealant work can’t fix
Before you book, it’s worth knowing the limits:
- Guttering that needs replacing
- Rotten or damaged fascia boards
- Blocked downpipes
If you’re not sure, just call 0345 464 0079 or send us an email and we will give you a straight answer before you book.

Do you clean gutters?

South Darenth buildings and the weather
With historic houses such as Lullingstone Castle (about 3.9 miles south-west) nearby, there’s older building stock in the area around South Darenth as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material. The South East is one of 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 live in an older home near The Parish Church of Saint Mary, older walls, gutters and the joints where extensions meet them need a flexible sealant. Rented homes near Farningham Road station change hands often, and a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking.
