Questions from Nettleden
Do you cover Nettleden for gutter sealing?
Yes, Nettleden is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or drop us an email and tell us what needs doing.
I let a flat near Berkhamsted station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we will give you a clear price.
Are you insured?
Yes. Full insurance covers our work.
Is sealant enough for a gutter that has dropped?
No. A sagging gutter pulls its joints apart, so the brackets need fixing first.
Can you seal over the old sealant?
No. The old sealant always comes out first, so the new sealant bonds properly.
Can I choose the sealant colour?
In most cases you can choose. We will explain which colours are available.
What guarantee comes with the job?
Our one-year guarantee covers every job, gutter and fascia work included.
Will you clear out my gutters?
We clear what’s around the joints we work on. A full clean of the gutters isn’t part of it.
Gutter sealing for homes and businesses in Nettleden
Open fascia and soffit joints spoil the roofline and can let weather in. They’re sealed in a matching colour where possible. We work on gutter end caps, garage door frames and roofline trims, and the jobs we see most are open joints in fascias and soffits and damp patches inside below a leaking gutter.
Around Nettleden, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points, and they need the right sealant at the right depth.
We stand behind the work with a 12-month guarantee, so you’re covered after we have gone.

DIY sealant or a professional job?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Looking after it afterwards
After the cure time, these simple habits help:
- Clean out the gutters once or twice a year
- Rest ladders on the wall, not the gutter
- Look for streaks or damp on the wall below gutters
- Watch for drips in a downpour
Clear the gutters once or twice a year, so water drains away past the joints. Standing water strains every seal.
A drip from a gutter joint won’t stop on its own. Water keeps hitting the same part of the wall, which can lead to staining and damp.
How the job changes by surface
Roofline trims
We reseal trim joints with an exterior sealant suited to the material.
Gutter end caps
A leaking end cap sends water straight down the wall. It’s a small job to fix.
Why it’s worth doing now in Nettleden
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. In a small place like Nettleden, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

How the visit works
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, do the work and tidy away. Most jobs take an hour or two for a few joints, longer for a full run. Somewhere like Nettleden needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First, we find the drip and check the gutter is not cracked or sagging.
- Old sealant and dirt are removed from the joint.
- We make sure the joint is dry before sealing.
- 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’re there.
Getting ready for the visit
- Let us know about earlier repairs to the joints
- Keep children and pets away from the work area
- Let us know about parking restrictions

Outside joints around Nettleden
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you look after a building such as Great Gaddesden Church of England Primary School, larger buildings have long runs of movement joint that eventually need resealing. In the older streets around Church of St Lawrence, old and new materials meet at the roofline and walls, which is where sealant earns its keep. Rented homes near Berkhamsted station change hands often, and a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking.
