How we handle gutter sealing in Hillyfields
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. We work on roofline trims, uPVC fascias and gutter joints, and the jobs we see most are fascia boards with gaps between them and old sealant on roofline trims that has split.
Houses in smaller places like Hillyfields can stand more in the open than those in a built-up town, so exposed walls and rooflines take more wind-driven rain. Joints on those sides are usually the first to go.
Every job comes with our 12-month guarantee.

For landlords and businesses
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
If you manage several properties in or around Hillyfields, several properties can be quoted together. Just tell us the addresses and what each one needs.
How the visit works
There’s no need to move everything out before we come, just the space around the work. Everything nearby is protected, and the job takes a few hours, depending on the number of joints and the access for a typical job. A visit to Hillyfields is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We look at where the water is coming from and check the gutter isn’t broken or sagging.
- We clean out the joint and take out the old sealant.
- We make sure the joint is dry before sealing.
- An exterior or gutter sealant is applied to the joint.
- We look along the gutter and clear debris around the joints.
How to prepare
- Keep pets and children clear of the area while we work
- Mention any leaks or damp you’ve noticed
- Tell us about access, such as stairs, a lift or high-level joints

Questions from Hillyfields
Is gutter sealing in a coastal place like Hillyfields any different?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. Walls facing the sea are usually the first to need attention.
Will you come out to Hillyfields?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Where are you based?
Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.
Are you insured?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
When is the sealant fully cured?
Most sealants are touch-dry well before they’re fully cured. We’ll tell you how long to leave the joint.
Can you seal fascia and soffit joints?
Yes, often alongside gutter joints. Each joint is cleaned and sealed.
Will sealant fix a dripping gutter joint?
Most of the time. A sagging or cracked gutter needs more than sealant, and we’ll tell you.
Which products do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we’ll explain our choice.
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Get leaks sealed before the wet months
- Rest ladders on the wall, not the gutter
- Look along the fascias for open joints
- Do not leave a sagging gutter
Keep the gutters clear of leaves and moss, so water drains away past the joints. Standing water strains every seal.
Leaking gutter joints get worse over time. The same spot gets soaked every time it rains, which can lead to staining and damp.

DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again.
What gutter sealing looks like in Hillyfields
Hillyfields is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on gutter, fascia and roofline joints, especially on the side facing the sea. With historic houses such as Southampton Tudor House and Garden (about 3.7 miles south-east) nearby, there’s older building stock in the area around Hillyfields as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
In the older streets around All Saints, older walls, gutters and the joints where extensions meet them need a flexible sealant. If you let a flat or house near Redbridge station, a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking.
