FAQs for Southcourt
Can you help a landlord with a rental near Aylesbury 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 send you a clear quote.
Is Southcourt within the area you cover?
Yes. Southcourt is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
What guarantee comes with the job?
Our 12-month guarantee applies on every job.
Will sealant fix a dripping gutter joint?
Generally, if the gutter is sound. We clean and dry the joint before sealing so the seal holds.
Where is Mr Mastic based?
We are a Crawley-based firm. Our area covers South East England, London and Scotland.
Is it OK to seal over old sealant?
No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. We remove it all first.
Can you match the sealant colour?
Most of the time, yes. We’ll explain which colours are available and agree one before any work starts.
Do the sealants smell?
That depends on the sealant. Some products have a noticeable smell, others very little.
Gutter sealing in Southcourt, done properly
For gutter sealant to hold, the joint has to be clean and dry. That is why we take out the old sealant and dirt first and the joint is dried before the new sealant goes in. Common call-outs are for end caps that drip every time it rains and water running down the wall below the gutter, on gutter end caps, uPVC fascias and roofline trims.
In a smaller place like Southcourt, some homes face open ground, and walls and rooflines facing the weather take the worst of it. Joints on those sides are generally the first to go.
All of our work is guaranteed for twelve months, in Southcourt and everywhere else we cover.

How the job changes by surface
Gutter joints
Most gutter leaks start at a joint between sections. They’re cleaned out, dried and resealed.
Roofline trims
Roofline trims rely on sealant at their joints. When it splits, water can get behind.

Southcourt buildings and the weather
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you let a flat or house near Aylesbury station, leaking gutter joints on a rental are best caught before they stain the walls. If you look after a building such as Ashmead Combined School, its movement joints, gutters and trims need looking after like any other building’s.

When to call us in Southcourt
Roofline sealant ages in sun and rain. It goes hard, cracks and pulls away after some years.
Signs it’s time to call us include:
- Quick sealant fixes on gutters that didn’t last
- Garage door frames letting rain in
- Open joints in fascias and soffits
- Damp patches inside below a leaking gutter
In the older streets around Church of the Good Shepherd, an extension built onto an older house moves differently, and the joint between them takes the strain.

How to look after the new joints
So the new joints stay in good condition:
- Keep the gutters clear of debris
- Check the gutters during heavy rain
- Keep an eye out for wet patches below a joint
- Have sagging gutters refixed early
Leave the new sealant to cure as we advise before poking or cleaning near it.
Split sealant on fascias and trims lets water in behind. Sealing it early keeps the boards behind dry and the wall below.
Why it’s worth doing now in Southcourt
Leaving a leaking end cap can send water down the wall all winter. Resealing it is a quick job compared with treating damp later. Homes in smaller places like Southcourt can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

We regularly work with letting and managing agents. Tell us the address, the job and how access works and we will give you a quote.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
Should I try it myself first?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
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. All the old material has to come out first.
What we do, step by step
Every visit runs the same way: we look at the joints together, protect the area around them, carry out the job and clear up. Most jobs take a few hours, depending on the number of joints and the access. In a smaller place like Southcourt, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- We look at the gutters, fascias and trims and agree the joints to seal.
- We clean out each joint.
- We make sure everything is dry.
- We apply exterior or gutter sealant and finish it neatly.
- The joints are checked once sealed.
How to prepare
- Move anything stored near the joints
- Mention any parking rules near the property
- Let us know if you’ve seen damp or leaks
