Gutter sealing in Copnor
Across Copnor, we reseal gutter joints, end caps and roofline trims. Single-storey and low gutters are simple to reach, and for higher work, tell us about access and we’ll confirm what’s needed. We work on gutter joints, garage door frames and gutter end caps, and the jobs we see most are fascia boards with gaps between them and old gutter sealant that has let go.
In a smaller place like Copnor, some homes face open ground, so exposed walls and rooflines take more wind-driven rain. That’s where gutter joints and wall joints tend to fail first.
You’re covered for a year from the day we finish. If there’s a problem with it, please phone 0345 464 0079 or email us.

DIY sealant or a professional job?
If you’ve already had a go yourself, that is fine. We cut it out and start again.
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.
Work for landlords, hotels and businesses
Hotels need rooms back in use, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
We regularly work with letting and managing agents. Tell us the address, the job and how access works and we’ll quote.
When something else is needed
We’d rather tell you now than do work that will not last, so here’s what sealant cannot put right:
- A gutter length that has split
- Water backing up from a blocked pipe
- Brackets that have snapped or loosened
If in doubt, call 0345 464 0079 or drop us an email and we will say what we think.
Joints and surfaces we work on
- uPVC fascias
- Roofline trims
- Garage door frames
- Soffit joints

What happens on the day
There is not much for you to do on the day. Point us to the joints and we’ll get on with it. The job generally takes a few hours, depending on the number of joints and the access from start to finish. For a job in Copnor, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We find where the water is coming from and check the gutter is sound.
- We remove the old sealant and clean the joint.
- The joint is dried before sealing.
- We seal the joint with a sealant made for gutters.
- We check the run and clear debris near the joints.
Before we arrive
- On commercial sites, let us know about site rules
- Let us know if you’ve seen damp or leaks
- Mention any tricky access

Do you cover smaller places like Copnor?
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.
Can you help a landlord with a rental near Fratton station?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before any work starts.
Can you work on commercial sites?
Yes. We have worked for hotels, offices and other businesses.
Do you offer different sealant colours?
We will suggest a colour to suit the surroundings. The choice depends on the product the joint needs.

How long does the job take?
As a guide, most jobs take a few hours, depending on the number of joints and the access. Bigger jobs take longer, and we’ll tell you how long to expect.
Do you remove the old sealant?
Yes, always, and completely. New sealant will not bond properly to old, so the joint is cleaned back first.
What about gutters on a second or third storey?
Low gutters are simple to reach. If it’s higher up, let us know and we will confirm the access.
Surface by surface
Garage door frames
Failed sealant around a garage door frame lets water in. It’s removed and renewed.
uPVC fascias
Joints between fascia boards can open over time. We seal them neatly with a matching sealant where possible.

Walls and rooflines in Copnor
Copnor is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on gutter, fascia and roofline joints, which can dry out and crack sooner where a building faces the weather. Historic houses like Warblington Castle (about 4.8 miles north-east) are a reminder that the area around Copnor has older buildings as well as new. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
For an older house near a landmark such as Church of St Alban, older walls, gutters and the joints where extensions meet them need a flexible sealant. For landlords with property near Fratton station, a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside.
