About our gutter sealing in Hill End
Many dripping gutters are just a failed joint or end cap. We clean out the joint, dry it and reseal it with a sealant made for guttering. If the gutter is broken or sagging, we will tell you. We are often asked to deal with cracked sealant along roofline trims and earlier gutter repairs that have peeled off, on roofline trims, soffit joints and gutter joints. Whether you are looking for a local mastic man, a sealant applicator or a sealant contractor in Hill End, Mr Mastic can help.
Modern London flats rely on sealed movement joints and cladding joints. Older terraces have their own weak points: gutter joints, roofline trims and the joint where an extension meets the original wall.
Whatever the size of the job, you get the same 12-month guarantee.

Common problems we fix in Hill End
Gutter joints depend on seals that wear out. Sun and cold make the gutter expand and contract and that movement opens up tired joints.
The most common problems we see are:
- Earlier gutter repairs that have peeled off
- Old sealant on roofline trims that has split
- Dripping gutter ends
- Open joints in fascias and soffits
If you look after a building such as Harefield Infant School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Work for landlords, hotels and businesses
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
For anyone letting property in or around Hill End, jobs at different addresses can be quoted together. Just tell us the addresses and what each one needs, and pictures by email help.
Should I try it myself 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.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Aftercare tips
A little care helps the new joints last. We recommend:
- Deal with a drip before winter
- Check that water runs out of the downpipes
- Clear leaves and moss from the gutters
- Rest ladders on the wall, not the gutter
Give the sealant the cure time we tell you before poking or cleaning near it.
The sooner a gutter leak is sealed, the less water reaches the wall. If we find a bigger problem, we will tell you.
Hill End: your questions answered
Is parking an issue for gutter sealing in Hill End?
Parking in Hill End, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly.
Can you help a landlord with a rental near Rickmansworth station?
Yes, we work for landlords and letting agents. You can call 07833 053749 or drop us an email with the address and a few details, and we will give you a fixed price before work begins.
Should I try DIY first?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Do you remove the old sealant?
Yes, every time. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
Is sealant enough for a gutter that has dropped?
Not for long. The movement opens the joint again so the gutter has to be refixed first.
When is the sealant fully cured?
That depends on the sealant used, so follow the cure time we give you when we finish.
What should I tell you?
Just the basics: the address or postcode, what’s wrong and any access issues. Then ring 07833 053749 or send us an email.
Do I have to be there?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.

Outside joints around Hill End
Historic houses like Ickenham Hall (about 4.1 miles south-east) are a reminder that the area around Hill End has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. 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.
If you live in an older home near Harefield Baptist Church, older walls, gutters and the joints where extensions meet them need a flexible sealant. If you let a flat or house near Rickmansworth station, leaking gutter joints on a rental are best caught before they stain the walls.
