Gutter Sealing in Knockholt
Specialist gutter sealing for Knockholt: careful preparation, the right product and tidy work. Call for a quick quote.
- Garage door frames letting rain in
- Old gutter sealant that has let go
- Cracked sealant along roofline trims
Aftercare tips
To keep the joints looking good and working properly:
- Glance at the soffit joints now and then
- Look for streaks or damp on the wall below gutters
- Clean out the gutters once or twice a year
- Watch for drips in a downpour
Leave the new sealant to cure as we advise before poking or cleaning near it.
If an end cap is dripping, deal with it before winter. A winter of drips can lead to damp patches inside.
Gutter sealing in Knockholt, done properly
Our work covers gutter joints and end caps as well as fascias and soffits plus roofline trims and garage door frames. It’s all about the joints rather than new guttering. We work on gutter joints, soffit joints and gutter end caps, and the jobs we see most are water dripping where gutter sections meet and old gutter sealant that has let go.
Outside joints can only be sealed when they’re dry, so work in Knockholt is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

Quotes for gutter sealing in Knockholt
The price is agreed before any work begins. It’s based on:
- How much there is to do
- How easy the joints are to reach
- The old material and how stubborn it is
- How many rooms, windows or areas are involved
Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you are not sure whether it needs doing, ring 0345 464 0079 or email us for an honest opinion and a quote.

Signs you need gutter sealing in Knockholt
Gutter joints rely on seals that age. Sun and cold make the gutter expand and contract, and old seals crack or slip.
Signs it’s time to call us include:
- Trim joints where the sealant has failed
- Rain getting in around a garage door
- Water running down the wall below the gutter
- End caps that drip every time it rains
In the older streets around St Katharine's Church, an extension built onto an older house moves differently, and the joint between them takes the strain.
What your quote should include
- What happens if the job turns out different
- What insurance they hold
- Which sealant they’ll use, and why
- What preparation is included
Different surfaces, different methods
Soffit joints
We choose a sealant colour that suits the soffit, where one is available.
Gutter joints
A dripping joint doesn’t always mean a failed gutter. Resealing is usually enough.
What we do, step by step
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, do the work and tidy away. Most jobs take anything from an hour or two to a few hours. For a village or hamlet like Knockholt, the journey is planned in advance: 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.
- We start by tracing the leak and checking the gutter itself is sound.
- Old sealant and dirt are removed from the joint.
- The area is dried so the sealant can bond.
- We seal the joint with a sealant made for gutters and outdoor use.
- We look along the gutter and clear debris around the joints.
Preparing for the visit
- Tell us about any water getting in
- Tell us if parking is tricky
- Keep pets and children clear of the area while we work

Your questions about gutter sealing in Knockholt
Do you cover Knockholt for gutter sealing?
Yes, Knockholt is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or send us an email with a few details of the job, and we’ll give you a clear price.
I let a flat near Knockholt station. Can you help?
Yes. We work for letting agents and landlords as well as householders. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
Can new sealant go over the old?
No, it won’t last. It can look neat for a few weeks, but the new layer lifts away from the old one. The old sealant has to come out completely.
Can you quote for more than one area?
Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Can I choose the sealant colour?
Normally, yes. White, clear and grey are common, and other colours are available for many products, and we agree the colour with you before we start.
Is sealant enough for a gutter that has dropped?
Not for long. The joint will pull apart so the gutter has to be refixed first.
Do the sealants smell?
Possibly a little. It fades as the sealant cures.
Are you insured?
Yes, we’re fully insured.
