Gutter sealing for homes and businesses in Cricklewood
Many dripping gutters are just a failed joint or end cap. The joint is cleaned, dried and resealed with a sealant made for guttering. If the gutter itself has failed, we say so. We work on gutter end caps, garage door frames and uPVC fascias, and common reasons people get in touch are damp on an inside wall under a dripping gutter and leaking gutter joints and stop ends.
Outside work in London starts with access: side passages, upper floors and where to park. For a home in Cricklewood, tell us how high the joints are and how to reach the back of the building.
A one-year guarantee comes as standard, so you are covered after we have gone.

When to call us in Cricklewood
Water spilling over a blocked gutter is often mistaken for a leak. A blocked downpipe makes water back up so we check the cause first.
Any of these means the joints need attention:
- Failed sealant on a garage door frame
- Internal damp traced to a gutter joint
- Earlier gutter repairs that have peeled off
- Drips from gutter joints and end caps
As a London address, Cricklewood can be tricky for parking: let us know about parking bays, permits or a driveway.

How to look after the new joints
A little care helps the new joints last. Our advice:
- Watch the wall under the gutters for staining
- Don’t lean ladders against the gutter itself
- Clear leaves and moss from the gutters
- Glance at the soffit joints now and then
Make sure downpipes aren’t blocked 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.
Why it’s worth doing now in Cricklewood
Leaving a leaking end cap can send water down the wall all winter. It’s a small job to put right compared with treating damp later. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and by the time it shows on a wall or ceiling in Cricklewood, the repair is bigger than the sealant job would have been.
The cost depends on how much there is to do, 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.

Your questions about gutter sealing in Cricklewood
Do you cover Cricklewood for gutter sealing?
Yes. Our work covers London and the South East, and Cricklewood is part of that. Just phone 0345 464 0079 or drop us an email with a few details of the job, and we will give you a clear quote.
Can you help a landlord with a rental near Cricklewood station?
Yes. We work for letting agents and landlords as well as householders. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear price.
Can I do it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.
Do the sealants smell?
Possibly a little. Any smell clears as the sealant cures, and ventilation helps.
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 will tell you how long to expect.
Will the old sealant be removed?
Yes, every time. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
Is it messy?
Tidy work is part of the job. We protect what’s around the joints.
Is gutter cleaning part of the job?
We clear debris around the joints we are sealing. Full gutter cleaning is a separate job.
What affects the cost of gutter sealing
The price is agreed before any work begins. It takes into account:
- The amount of work
- Working hours on commercial sites
- The type of sealant required
- The number of rooms or windows
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part.
What to tell us for a quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- Access, such as stairs, a lift or height
- The problem you’ve noticed
- The rough size of the job
- Where the job is, and your postcode

What we can’t put right
New sealant can’t fix everything, and we’d rather say so up front. It will not solve:
- Water backing up from a blocked pipe
- Gutters that have dropped or pulled away
- Boards that have decayed or split
If in doubt, call 0345 464 0079 or send us an email and we’ll say what we think.

Gutter sealing in Cricklewood: local notes
With historic houses such as Fenton House (about 1.7 miles east) nearby, there’s older building stock in the area around Cricklewood as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Homes close to St Gabriel's Church include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move. If you look after a building such as Anson Primary School, its movement joints, gutters and trims need looking after like any other building’s.
