Roofline trims
We reseal trim joints with an exterior sealant suited to the material.
Gutter joints
A gutter joint has to cope with movement and standing water. A gutter sealant made for the job holds best.
Gutter sealing in Woodside Park, done properly
Failed sealant round a garage door frame lets rain blow in. We cut out the old sealant and reseal the frame with an exterior sealant. If you have fascia boards with gaps between them and rain getting in around a garage door, we can help.
Outside work in London starts with access: side passages, upper floors and where to park. In Woodside Park, joints up high may need ladders or other access, which is worth talking through when you book.
Whatever the size of the job, you get the same one-year guarantee in Woodside Park and across Greater London.

What happens on the day
Once we are on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours, depending on the number of joints and the access. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.
- We find where the water is coming from and check the gutter is sound.
- We remove the old sealant and clean 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
- On commercial sites, let us know about site rules
- Mention any parking rules near the property
- Tell us about access, such as stairs, a lift or high-level joints

What we’re called out for in Woodside Park
When a gutter sags, its joints open. Sealing won’t hold if the gutter keeps dropping, so the gutter needs refixing first.
Any of these means the joints need attention:
- Garage door frames letting rain in
- Quick sealant fixes on gutters that didn’t last
- End caps that drip every time it rains
- Water dripping where gutter sections meet
For landlords with property near Oakleigh Park station, leaking gutter joints on a rental are best caught before they stain the walls.
Questions to ask before booking
- How much experience the applicator has
- What product goes in the joint
- How the colour is chosen
- What preparation is included
FAQs for Woodside Park
Can you help a landlord with a rental near Oakleigh Park station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before any work starts.
Is parking a problem for a job in Woodside Park?
Parking in Woodside Park, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
Will you leave a mess?
Tidy work is part of the job. We protect what’s around the joints, and we clear up when we are done.
How long will you be here?
Typically it takes a few hours, depending on the number of joints and the access. Bigger jobs take longer, and we’ll say how long yours will take.
Will sealing fix a sagging gutter?
Sealant will not hold a sagging gutter. The gutter needs refixing by a gutter installer.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Is gutter cleaning part of the job?
We clear what’s around the joints we work on. A full clean of the gutters is not part of it.
Do you hold any approvals?
Yes. We are an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
Honest limits
It helps to know what we can’t do:
- Leaks from the roof rather than a joint
- Downpipes that are blocked or broken
- Rotten or damaged fascia boards
If in doubt, call 0345 464 0079 or drop us an email and we’ll say what we think before you book.
Surfaces we seal
- Soffit joints
- Gutter end caps
- Garage door frames
- Gutter joints
- uPVC fascias
- Roofline trims
Aftercare tips
How long the joints last depends on use and care. We suggest:
- Look along the fascias for open joints
- Keep an eye out for wet patches below a joint
- Keep downpipes clear
- Watch for drips in a downpour
Make sure downpipes aren’t blocked, so water can get away. Blockages push water back along the gutter.
The sooner a gutter leak is sealed, the less water reaches the wall. If we find a bigger problem, we will tell you.
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. All the old material has to come out first.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.

What gutter sealing looks like in Woodside Park
In terraces and conversions, gutters and walls are often shared with the neighbours, so it’s worth agreeing who is responsible before work starts. With historic houses such as Heath Hall (about 3 miles south) nearby, there’s older building stock in the area around Woodside Park 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.
For site and facilities teams at buildings such as Northside Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. In the older streets around Saint Barnabas' Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Why act early in Woodside Park
Sealing over a dirty, wet joint is a quick fix that rarely lasts but it tends to peel off. Proper preparation is the difference. Converted houses in London often have a bathroom above someone else’s living room, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Putting it right early is much less trouble for homes in Woodside Park.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
