About our gutter sealing in Leagreen
Across Leagreen, we reseal gutter joints, end caps and roofline trims. Low-level work is straightforward, and for higher work, tell us about access and we’ll confirm what’s needed. Common call-outs are for drips from gutter joints and end caps and garage door frames letting rain in, across roofline trims, uPVC fascias and soffit joints.
In a village or hamlet like Leagreen, older cottages and farm buildings often stand in the open, where walls and rooflines take the weather head on. Joints on those walls need a sealant that moves with the building and stays in place.
Big or small, you get the same 12-month guarantee.

How the visit works
When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours, depending on the number of joints and the access. In a small place like Leagreen, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We find where the water is coming from and check the gutter is sound.
- The old sealant and dirt are cleaned out of the joint.
- We dry the joint so the new sealant can bond.
- We seal the joint with a sealant made for gutters.
- The gutter is checked and debris around the joints cleared.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children
- Where the joints are inside, avoid wetting them before we arrive
- On commercial sites, let us know about site rules

Questions from Leagreen
Do you cover smaller places like Leagreen?
Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
I let a flat near New Milton station. Can you help?
Yes, landlords and agents are among the people we work for. You can ring 0345 464 0079 or email us with the details for a clear quote.
How long should I leave it?
Cure times vary by product and the conditions. We tell you how long to leave it before we go.
Do you guarantee gutter sealing?
All our work carries a one-year guarantee.
Which products do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Do you remove the old sealant?
Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.
How long will you be here?
It depends on the size of the job, but as a guide it takes an hour or two for a few joints, longer for a full run. We will give you a better idea when we quote.
Aftercare tips
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Look for streaks or damp on the wall below gutters
- Check that water runs out of the downpipes
- Sort out a dripping joint early
- Clear leaves and moss from the gutters
Leave the new sealant to cure as we advise before poking or cleaning near it.
Early sealing limits how much water hits the wall. We will let you know if the gutter needs more than sealant.
What affects the quote in Leagreen
We quote each job individually. This is what makes a difference:
- Whether the work is at height
- How many areas need sealing
- How much old sealant there is and how hard it is to remove
- Any working-time requirements on site
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we will explain what it covers.
Asking for a quote
When you contact us, these details help:
- How we’d reach the joints
- The type of property
- If someone has resealed it before
- How many joints, rooms or windows are involved
For a quote, phone 0345 464 0079 or drop us an email and tell us where the job is and what the problem looks like. We’ll give you a clear quote before any work starts.
DIY sealant or a professional job?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again.
Honest limits
We’d rather tell you now than do work that won’t last, so these are the limits:
- Fascias that need replacing
- Problems with the roof covering
- Water backing up from a blocked pipe
If you are not sure, just ring 0345 464 0079 or email us and we will give you a straight answer before booking.

What we are called out for in Leagreen
When a gutter sags, its joints open. Resealing a sagging joint will not last so the brackets need attention first.
Most people get in touch after spotting one of these:
- Water running down the wall below the gutter
- Rain getting in around a garage door
- End caps that drip every time it rains
- Earlier gutter repairs that have peeled off
In the older streets around Church of All Saints, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Why act early in Leagreen
Sealant won’t clear a blocked downpipe. We check the cause first and tell you if something else is needed. Around Leagreen, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
Why choose Mr Mastic in Leagreen
- Every job guaranteed for a year
- Full insurance on every job
- You choose the colour before work begins
- Anti-fungal silicone where joints get wet

Gutter sealing in Leagreen: local notes
Leagreen is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on gutter, fascia and roofline joints, especially on the side facing the sea. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Schools such as Hordle CofE (VA) Primary School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Letting a property close to New Milton station? Then leaking gutter joints on a rental are best caught before they stain the walls.
