Gutter sealing for homes and businesses in Childs Hill
We don’t replace gutters, fascias or roofs. What sealant does is close joints; it will not fix a broken bracket, a cracked section or a blocked downpipe. Typical jobs include trim joints where the sealant has failed and drips from gutter joints and end caps, across uPVC fascias, roofline trims and soffit joints.
Newer London blocks are built with movement joints in brick and render, and with cladding joints sealed with mastic. Period houses have different weak points, such as gutter joints, trims and the line where an extension meets the old wall, and both kinds of building are found across London.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Childs Hill questions
Is parking a problem for a job in Childs Hill?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. That way the visit can be planned around it.
I let a flat near Cricklewood station. Can you help?
Yes, we work for landlords and agents. Just call 0345 464 0079 or email us and tell us about the property, and we will send you a clear quote.
Do you replace gutters or fascias?
We don’t replace gutters or fascias. If a gutter is broken or sagging, we’ll tell you so you can call the right trade.
Will you clear out my gutters?
We clear what’s around the joints we work on. Full gutter cleaning is a separate job.
Do you seal gaps in fascias and soffits?
Yes. Open joints along uPVC fascias and soffits can be sealed in a colour to suit.
Is it possible to stop a gutter joint dripping with sealant?
Often, yes. A clean, dry joint resealed with gutter sealant generally stops the drip. A split or warped section needs replacing.
Are you insured?
Yes. We’re fully insured.
How long before the joint can be used?
It depends on the product. Before we leave, we will tell you the cure time.
How the job changes by surface
Soffit joints
Open soffit joints let draughts in. A neat seal closes them.
uPVC fascias
Joints between fascia boards can open over time. They’re sealed tidily with a matching sealant where possible.
Should I try it myself 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, then guaranteed for a year.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
How it works
Once we are on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes anything from an hour or two to a few hours. In a London area like Childs Hill, the main things to plan are parking and access: let us know about parking, the floor we will be working on and any lift or shared entrance.
- 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.
- A gutter sealant is applied to the joint.
- The gutter is checked and debris around the joints cleared.
How to prepare
- On commercial sites, let us know about site rules
- Try not to wet indoor joints just before the visit
- Mention any leaks or damp you’ve noticed
Getting a quote
It all starts with a short chat. Describe the problem, the location and the size of the job, and we will explain how we’d tackle it. When it suits you, ring 0345 464 0079 or send us an email.

Outside joints around Childs Hill
London terraces and converted houses often share gutters, downpipes and walls, so check who is responsible for the outside before booking. Historic houses like Heath House (about 0.7 miles east) are a reminder that the area around Childs Hill has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.
As a London address, Childs Hill can be tricky for parking: let us know about parking bays, permits or a driveway. Letting a property close to Cricklewood station? Then a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking.

What we’re called out for in Childs Hill
End caps get knocked or pushed by water. Once the seal behind them fails, they drip.
Keep an eye out for these signs:
- Leaking gutter joints and stop ends
- Internal damp traced to a gutter joint
- Open joints in fascias and soffits
- Old sealant on roofline trims that has split
For site and facilities teams at buildings such as All Saints' CofE Primary School NW2, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
Questions to ask before booking
- Whether they seal over old material or remove it
- What product goes in the joint
- Who turns up on the day
- When the joint can take water or movement
Work for landlords, hotels and businesses
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
For anyone letting property in or around Childs Hill, several properties can go on one quote. Just tell us the addresses and what each one needs.
How to look after the new joints
To keep the joints looking good and working properly:
- Clear leaves and moss from the gutters
- Look along the fascias for open joints
- Look at the gutters while it’s raining
- Watch the wall under the gutters for staining
Make sure downpipes are not blocked, so water can get away. Blockages push water back along the gutter.
Early sealing limits how much water hits the wall. If we find a bigger problem, we will tell you.
Leave it or put it right?
Sealant will not clear a blocked downpipe. We look at what’s really happening and tell you if something else is needed. 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 Childs Hill.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all make a difference.
