About our gutter sealing in Great Dunmow
Gutter and fascia replacement isn’t our trade, and nor is roofing. Sealant fixes joints; it won’t fix a broken bracket, a cracked section or a blocked downpipe. We work on gutter joints, gutter end caps and soffit joints, and the jobs we see most are trim joints where the sealant has failed and drips from gutter joints and end caps.
Houses in smaller places like Great Dunmow can stand more in the open than those in a built-up town, so exposed walls and rooflines take more wind-driven rain. Joints on those sides are usually the first to go.
All our work is covered by a 12-month guarantee, wherever you are in Essex.

Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

Managing a site like Dunmow St Mary's Primary School? Then its movement joints, gutters and trims need looking after like any other building’s.

Do you need gutter sealing in Great Dunmow?
Stop ends take pressure from water running along the gutter. If the seal fails, water escapes at the end.
Most people get in touch after spotting one of these:
- Cracked sealant along roofline trims
- Water dripping where gutter sections meet
- End caps that drip every time it rains
- Earlier gutter repairs that have peeled off
For landlords with property near Stansted Airport station, a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking.

How it works
There isn’t much for you to do on the day. Point us to the joints and we’ll get on with it. The work itself takes a few hours, depending on the number of joints and the access, including the tidy-up. A visit to Great Dunmow is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- First, we find the drip and check the gutter is not cracked or sagging.
- 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 check the run and clear any debris we find while we’re there.
How to prepare
- Tell us about any previous sealing or DIY attempts
- Mention any leaks or damp you’ve noticed
- Clear the area around the work

Advice
DIY sealant or a professional job?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.
Quotes for gutter sealing in Great Dunmow
The price is agreed before any work begins. It takes into account:
- Access and height
- Which sealant suits the joint
- Mould in or behind the old joints
- Working hours on commercial sites
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
Helping us quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- Any access issues, like height or stairs
- Whether it has been sealed before
- Where the property is
- How many joints, rooms or windows are involved
We quote each job on its own, so start by telling us what you need. Just ring 0345 464 0079 or drop us an email with the details.
Looking after it afterwards
Aftercare is simple, and it makes a real difference:
- Rest ladders on the wall, not the gutter
- Deal with a drip before winter
- Have sagging gutters refixed early
- Look at the gutters while it’s raining
Make sure downpipes aren’t blocked so the gutter can drain. Blockages push water back along the gutter.
Once roofline sealant splits, water can get behind it. Sealing it early keeps the boards behind dry and the wall below.
