Gutter sealing in Coleman Green
A leaking gutter joint marks the wall and wets the ground underneath. Resealing the joint is often all it needs, as long as the gutter is sound. We work on gutter end caps, gutter joints and soffit joints, and people most often call us about rain getting in around a garage door and water dripping where gutter sections meet.
Outside joints can only be sealed when they’re dry, so work in Coleman Green is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
Big or small, it’s backed by our one-year guarantee.

What affects the cost of gutter sealing

Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Watch for drips in a downpour
- Sort out a dripping joint early
- Keep ladders off the guttering
- Don’t leave a sagging gutter
Leave the new sealant to cure as we advise and avoid disturbing it.
Once roofline sealant splits, water can get behind it. Resealing early protects the boards and the wall below.
What gutter sealing looks like in Coleman Green
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. With historic houses such as Shaw's Corner (about 2.5 miles north) nearby, there’s older building stock in the area around Coleman Green as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.
Letting a property close to Welwyn Garden City station? Then a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside. Shaw's Corner, about 2.5 miles north, is one of the historic houses in the wider area around Coleman Green, and older homes nearby need a sealant that suits their walls.

DIY sealant or a professional job?
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
The process
A visit follows a simple pattern: we check the joints, 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. In a small place like Coleman Green, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at the gutters, fascias and trims and agree the joints to seal.
- 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
- Try not to wet indoor joints just before the visit
- Tell us about any water getting in
- Mention any tricky access

What should I tell you?
A short description and the location, with pictures by email if possible. We will ask anything else we need to know.

No, it will not last. It may look fine at first, but the new layer lifts away from the old one. The old sealant has to come out completely.
Is it possible to stop a gutter joint dripping with sealant?
Yes, as long as the gutter itself is in good order. The joint is cleaned and dried first so the seal holds.

Cure times vary by product and the temperature. Before we leave, we will tell you the cure time.

It depends on the size of the job, but most jobs take an hour or two for a few joints, longer for a full run. We’ll tell you when we quote.
