Gutter sealing for homes and businesses in Woolmer Green
A leaking gutter joint marks the wall and wets the ground underneath. Resealing the joint is often all it needs if the gutter isn’t damaged. If you have gaps along fascia and soffit joints and wet patches on the wall under a gutter joint, we can help.
Outside joints can only be sealed when they’re dry, so work in Woolmer Green is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Gutter joints
Gutter joints move and sit in water. A dedicated gutter sealant suits them.
Soffit joints
Open soffit joints let draughts in. A neat seal closes them.
Woolmer Green questions
Will you come out to Woolmer Green?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you work for landlords with property near Knebworth station?
Yes, landlords and agents are among the people we work for. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear price.
Can I do it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference.
Is the work guaranteed?
Every job comes with our 12-month guarantee, and we are fully insured.
Do you do commercial work?
Yes, regularly. Larger jobs can be planned room by room or area by area to suit the site.
Will there be a smell?
It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Are you ARBOMaster approved?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Can I do it myself?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
If you are 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 does not work out, we can still put it right.

What gutter sealing looks like in Woolmer Green
With historic houses such as Knebworth House (about 2 miles north-west) nearby, there’s older building stock in the area around Woolmer Green 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, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For landlords with property near Knebworth station, a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking. Homes close to Church of St Michael and All Angels include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain.
Woolmer Green is about 4 miles north of Welwyn Garden City, in Hertfordshire.

Advice
Aftercare tips
No joint lasts for ever, but care makes a real difference. Our tips:
- Keep ladders off the guttering
- Keep the gutters clear of debris
- Sort out a dripping joint early
- Check that water runs out of the downpipes
If a gutter starts to sag, get the brackets looked at. Movement will pull the joints open again.
The sooner a gutter leak is sealed, the less water reaches the wall. If we find a bigger problem, we will tell you.
