How we handle gutter sealing in Childwick Green
Sealant only bonds to a clean, dry joint. That is why we take out the old sealant and dirt first, then dry the joint before sealing. If you have earlier gutter repairs that have peeled off and end caps that drip every time it rains, we can help, on gutter joints, soffit joints and gutter end caps alike.
Around Childwick Green, older buildings can be stone, brick or timber-framed, many with extensions added later. Where one material meets another is where water normally gets in.
All our work is covered by a 12-month guarantee, wherever you are in Hertfordshire.

DIY sealant or a professional job?
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.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Work for landlords, hotels and businesses
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. Several properties can go on one quote.
Childwick Green buildings and the weather
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. With historic houses such as Childwickbury Manor (about 0.4 miles south-west) nearby, there’s older building stock in the area around Childwick Green as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
If you look after a building such as Townsend Church of England School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. In the older streets around Church of St Mary, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Childwick Green questions
Can you do gutter sealing in Childwick Green?
Yes. We work across London and the South East, and Childwick Green is part of that. Just call 0345 464 0079 or send us an email with a few details of the job.
Do you work for landlords with property near Harpenden station?
Yes, rental work is part of what we do. 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 we start.
Are you ARBOMaster approved?
Yes. We’re approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
Can you seal over the old sealant?
No, and we never do. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.
Do you replace gutters or fascias?
No. Our work is sealing joints and replacement is a job for an installer.
Can I do it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
What do you put in the joint?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Can you do several jobs on one visit?
Of course. Doing several areas at once is usually more efficient, so mention them when you ask for a quote.
