About our gutter sealing in Heronsgate
Many dripping gutters are just a failed joint or end cap. The joint is cleaned, dried and resealed using a gutter sealant. If the gutter is broken or sagging, we will tell you. We work on gutter end caps, garage door frames and uPVC fascias, and the jobs we see most are damp patches inside below a leaking gutter and rain getting in around a garage door.
In a village or hamlet like Heronsgate, older cottages and farm buildings often stand in the open, where walls and rooflines take the weather head on. Gutter joints and wall joints there need a sealant that can flex and stay put.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Leave it or put it right?
Replacing guttering is a much bigger job than sealing joints. If the gutter is sound and the drip is a joint a reseal is all it needs. If it has failed, we will tell you. Around Heronsgate, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.
Why us?
- We leave the area clean and tidy
- Full insurance on every job
- Trusted Arbo and Everbuild sealants
- We never seal over old sealant

How the visit works
The work is kept neat and contained to the joints we’re treating. The job generally takes an hour or two for a few joints, longer for a full run, and we explain the cure time before we leave. Somewhere as small as Heronsgate, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at where the water is coming from and check the gutter is not broken or sagging.
- We clean out the joint and take out the old sealant.
- The joint is dried, because sealant will not bond to a wet surface.
- We seal the joint with a sealant made for gutters and outdoor use.
- We check the run and clear any debris we find while we are there.
Before we arrive
- For indoor joints, keep the area dry beforehand if you can
- Mention any leaks or damp you’ve noticed
- Tell us about any previous sealing or DIY attempts

It depends on the access. Let us know the height and the ground below when you phone 0345 464 0079 or send us an email.
Do you take out the old sealant first?
Yes, always, and completely. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.

We need access to the joints, so we’ll agree that with you when we book. Indoors, that generally means someone at home.

Products from Arbo and Everbuild, among others, picked for each joint. We’ll tell you what we’re using and why.
Walls and rooflines in Heronsgate
With historic houses such as Chenies Manor House (about 2.4 miles north) nearby, there’s older building stock in the area around Heronsgate as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Managing a site like Chorleywood Primary School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. In the older streets around St John, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Surface by surface
Garage door frames
Resealing a garage door frame keeps rain and draughts out.
Roofline trims
Trims along the roofline are often finished with sealant. Split sealant lets water in.
How to look after the new joints
After the cure time, these simple habits help:
- Clear leaves and moss from the gutters
- Deal with a drip before winter
- Watch for drips in a downpour
- Get a dropping gutter looked at quickly
Make sure downpipes are not blocked so the gutter can drain. Blockages push water back along the gutter.
If an end cap is dripping, deal with it before winter. Water down the wall all winter can cause damp inside.

When to call us in Heronsgate
Gutter joints rely on seals that age. Temperature changes make gutters move, and old seals crack or slip.
Most people get in touch after spotting one of these:
- Earlier gutter repairs that have peeled off
- Water dripping where gutter sections meet
- Gaps along fascia and soffit joints
- Damp patches inside below a leaking gutter
Rented homes near Chorleywood station change hands often, and a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking.
