About our gutter sealing in Radwell
Sealant only bonds to a clean, dry joint. So the old sealant and grime come out first and the joint is dried before the new sealant goes in. If you are dealing with internal damp traced to a gutter joint and dripping gutter ends, we can help, on gutter end caps, roofline trims and soffit joints alike.
External sealant needs dry, clean surfaces, so work around Radwell is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
A 12-month guarantee comes as standard, so you are not left on your own once the job is done.

Can I do it myself?
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.

What gutter sealing looks like in Radwell
With historic houses such as Hinxworth Place (about 2.4 miles north) nearby, there’s older building stock in the area around Radwell as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For site and facilities teams at buildings such as Norton St Nicholas CofE (VA) Primary School, larger buildings have long runs of movement joint that eventually need resealing. Letting a property close to Baldock station? Then a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside. Homes close to Church of All Saints include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant.

Why act early in Radwell
Water from a leaking joint hits the same spot every time. Over time that can stain brickwork, mark render and encourage damp, so it’s worth sealing early. In a small place like Radwell, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

Different surfaces, different methods
Roofline trims
Sealing roofline trims is joint work only. A roofer deals with the roof itself.
Gutter joints
Most gutter leaks start at a joint between sections. We clean, dry and reseal them.
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Clean out the gutters once or twice a year
- Do not lean ladders against the gutter itself
- Get a dropping gutter looked at quickly
- Look at the gutters while it’s raining
Have a look at the gutter during a downpour now and then. It’s the easiest time to see a leak.
A leaking stop end is best sealed before the wet months. Water down the wall all winter can cause damp inside.
