If you have water dripping where gutter sections meet and water running down the wall below the gutter, we can help, whatever the surface.
Around Chainhurst, older buildings can be stone, brick or timber-framed, many with extensions added later. Where one material meets another is where water generally gets in.

Honest limits
To be straight with you, there are a few things sealant will not fix:
- Sagging gutters or broken brackets
- Blocked downpipes
- Boards that have decayed or split
Not sure which it is? You can phone 0345 464 0079 or email us and we’ll tell you honestly.
What we seal
- Soffit joints

- Roofline trims
- Gutter end caps
- Gutter joints
- Garage door frames
What the job involves on each surface
Soffit joints
Gaps at soffit joints can let in draughts and insects. A neat seal closes them.
uPVC fascias
We seal fascia joints, not replace the boards. If boards are damaged, we’ll tell you.
Why deal with it now?
Water from a leaking joint hits the same spot every time. Left, it can stain walls and lead to damp, so it’s worth sealing early. Where a wall is exposed, as many are in small places like Chainhurst, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are unsure, call 0345 464 0079 or email us for an honest opinion and a quote.

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Keep an eye out for wet patches below a joint
- Keep the gutters clear of debris
- Keep downpipes clear
- Look along the fascias for open joints
Keep the gutters clear of leaves and moss, so water drains away past the joints. Water left in a gutter tests every joint.
A drip from a gutter joint won’t stop on its own. Water keeps hitting the same part of the wall and that can cause damp inside.

When to call us in Chainhurst
Debris in the gutter keeps water sitting at the joints. Water that can’t drain works its way through a weak joint and drips through.
If you can see any of these, it’s time to have the joints looked at:
- Wet patches on the wall under a gutter joint
- Fascia boards with gaps between them
- Rain getting in around a garage door
- Damp on an inside wall under a dripping gutter
Rented homes near Marden station change hands often, and a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside.
Before you book anyone
- How much experience the applicator has
- What happens if the job turns out different
- Is VAT in the price?
- Whether they seal over old material or remove it
Should I try it myself first?
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.

How the visit works
There’s no need to move everything out before we come, only the area right around the joints. We protect the rest, and the job takes a few hours, depending on the number of joints and the access in most cases. Somewhere as small as Chainhurst, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we agree which joints need sealing.
- Each joint is cleaned and any old sealant removed.
- The joints are dried.
- The sealant is applied and finished.
- We check our work before we leave.
How to prepare
- Mention any sign-in or site rules at work premises
- Tell us about access, such as stairs, a lift or high-level joints
- Clear the area around the work

It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we will explain how we’d tackle it. When it suits you, ring 0345 464 0079 or email us.
