Gutter sealing in Charlton, done properly
Open fascia and soffit joints spoil the roofline and can let weather in. We seal them in a colour to suit where one is available. We work on gutter end caps, soffit joints and garage door frames, and people most often call us about trim joints where the sealant has failed and leaking gutter joints and stop ends.
Outside joints can only be sealed when they’re dry, so work in Charlton is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
Your job is guaranteed for a year, as with all our work.

Keeping the joints in good condition
To keep the joints looking good and working properly:
- Keep an eye out for wet patches below a joint
- Keep the gutters clear of debris
- Check that water runs out of the downpipes
- Don’t lean ladders against the gutter itself
Check the joints after heavy rain. Drips are easiest to spot while it’s raining.
Early sealing limits how much water hits the wall. If we find a bigger problem, we will tell you.
Work for landlords, hotels and businesses
Failed sealant is one of the commonest items on a check-out report. We can quote for more than one property at once.
Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.
Do you need gutter sealing in Charlton?
Debris in the gutter keeps water sitting at the joints. Standing water finds the weakest joint and drips through.
Signs it’s time to call us include:
- End caps that drip every time it rains
- Fascia boards with gaps between them
- Damp patches inside below a leaking gutter
- Streaks down the brickwork from a leaking joint
For an older house near a landmark such as The Parish Church of the Blessed Virgin Mary, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

The process
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take anything from an hour or two to a few hours. Somewhere like Charlton needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.

Can I do it myself?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
What gutter sealing looks like in Charlton
With historic houses such as West Dean House (about 1.7 miles west) nearby, there’s older building stock in the area around Charlton as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For site and facilities teams at buildings such as Singleton CofE Primary School, larger buildings have long runs of movement joint that eventually need resealing.
