Gutter sealing for homes and businesses in Hundred Acres
For gutter sealant to hold, the joint has to be clean and dry. So the old sealant and grime come out first and the joint is dried before the new sealant goes in. If you have streaks down the brickwork from a leaking joint and failed sealant on a garage door frame, we can help, whatever the surface.
In a village or hamlet like Hundred Acres, older cottages and farm buildings often stand in the open, so walls and rooflines take the full force of wind and rain. Joints on those walls need a sealant that moves with the building and stays in place.
A one-year guarantee comes as standard, so you are covered after we have gone.

Is Hundred Acres within the area you cover?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Does someone need to be in?
It depends on the job. Inside work needs someone to give us access.
Can new sealant go over the old?
No, because it fails. We remove every bit of old sealant first, so the new sealant bonds properly.
Are you insured?
Yes. Mr Mastic is fully insured.
Will it make a mess?
We keep the work tidy. We protect what’s around the joints, and the area is left clean when we finish.
Where is Mr Mastic based?
We’re based in Crawley, and we cover South East England, London and all of Scotland.
Can you fit new guttering?
No. Our work is sealing joints; replacing gutters and fascias needs a gutter or roofline installer.

The process
Good joint work is mostly preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. In total, it usually takes an hour or two for a few joints, longer for a full run. Somewhere like Hundred Acres needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by tracing the leak and checking the gutter itself is sound.
- Old sealant and dirt are removed from the joint.
- The joint is dried, because sealant won’t bond to a wet surface.
- An exterior or gutter sealant is applied to the joint.
- We check the run and clear any debris we find while we’re there.
Getting ready for the visit
- Mention any leaks or damp you’ve noticed
- Keep pets and children clear of the area while we work
- On commercial sites, let us know about site rules

Why deal with it now?
Water from a leaking joint hits the same spot every time. Over time that can stain brickwork, mark render and encourage damp so early sealing is worthwhile. Around Hundred Acres, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
The cost depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before work begins, so you know where you stand.
Why book with us

- Anti-fungal sanitary silicone in wet areas

Looking after it afterwards
Aftercare is simple, and it makes a real difference:
- Look at the gutters while it’s raining
- Look for streaks or damp on the wall below gutters
- Clear leaves and moss from the gutters
- Check fascia and soffit joints for gaps
Keep downpipes clear so the gutter can drain. A blocked pipe backs water up to the joints.
Split sealant on fascias and trims lets water in behind. Resealing early protects the boards and the wall below.
Common problems we fix in Hundred Acres
Sealant laid on a wet or dirty joint fails early. Some quick repairs peel off within a season or two for this reason.
Any of these means the joints need attention:
- Drips from gutter joints and end caps
- Open joints in fascias and soffits
- Quick sealant fixes on gutters that didn’t last
- End caps that drip every time it rains
Rented homes near Fareham station change hands often, and a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking.
