Our work covers gutter joints and end caps as well as fascias and soffits, along with roofline trims and garage door frames. It’s joint work rather than new guttering. If you’re dealing with garage door frames letting rain in and earlier gutter repairs that have peeled off, we can put it right, whatever the surface.
Outbuildings, garages and conservatories around homes in places like Welham Green add more joints to look after. Leaks usually start at a gutter end, a garage door frame or where an extension meets the house.

Outside joints around Welham Green
Hatfield, which Welham Green is part of, is one of England’s post-war new towns. Homes here were built in phases, many of them in the post-war decades, so whole streets can have gutters, trims and wall joints reaching the end of their life together. 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.
In the older streets around Church of St Mary the Virgin, older walls, gutters and the joints where extensions meet them need a flexible sealant. Managing a site like St Mary's Church of England Primary School? Then its movement joints, gutters and trims need looking after like any other building’s.

Questions from Welham Green
I let a flat near Welham Green station. Can you help?
Yes, we work for landlords and letting agents. You can phone 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before work begins.
Should the sealant in an older Welham Green home be renewed?
In most cases, yes, if it hasn’t been done for a while. Sealant doesn’t last for ever, and its life depends on use, cleaning and weather, and many homes in Welham Green may already be on their second or third set.
Do you guarantee gutter sealing?
All our work carries a one-year guarantee.
Can a leaking gutter joint be sealed?
In many cases, yes. Cleaning, drying and resealing the joint usually works. A split or warped section needs replacing.
Is it messy?
Very little: the area around the joints is protected first, and we tidy up before we go.
Can I choose the sealant colour?
In most cases you can choose. We will explain which colours are available and agree one before any work starts.
When is the sealant fully cured?
That depends on the sealant used, so please follow the time we give you.
Is it worth trying it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.
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
Joints between fascia boards can open over time. We seal them neatly in a suitable colour.
DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
