Gutter sealing for homes and businesses in Old Oak Common
Garage door frames let rain in when the sealant around them fails. We cut out the old sealant and reseal the frame with an exterior sealant. If you have wet patches on the wall under a gutter joint and garage door frames letting rain in, we can help, whatever the surface.
Newer London blocks are built with movement joints in brick and render, and with cladding joints sealed with mastic. Older terraces have their own weak points: gutter joints, roofline trims and the joint where an extension meets the original wall, and both kinds of building are found across London.
Your job is guaranteed for a year, as with all our work.

DIY sealant or a professional job?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Gutter sealing in Old Oak Common: local notes
London terraces and converted houses often share gutters, downpipes and walls, so it’s worth agreeing who is responsible before work starts. With historic houses such as Kelmscott House (about 2.5 miles south) nearby, there’s older building stock in the area around Old Oak Common as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
As a London address, Old Oak Common can be tricky for parking: let us know about parking bays, permits or a driveway. Homes close to Church of Eritrean Orthodox Brent include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move. Managing a site like Old Oak Primary School? Then its movement joints, gutters and trims need looking after like any other building’s.

How to look after the new joints
How long the joints last depends on use and care. We suggest:
- Get a dropping gutter looked at quickly
- Get leaks sealed before the wet months
- Keep ladders off the guttering
- Clean out the gutters once or twice a year
Check the joints after heavy rain now and then. It’s the easiest time to see a leak.
Rain getting in round a garage door frame can damage what’s stored inside. Resealing the frame is a quick job while the frame is sound.
What sealant work cannot fix
To be straight with you, some problems need a different trade:
- Fascias that need replacing
- Brackets that have snapped or loosened
- Water backing up from a blocked pipe
If in doubt, ring 0345 464 0079 or send us an email and we’ll say what we think before you book.

Your questions about gutter sealing in Old Oak Common
Is parking a problem for a job in Old Oak Common?
Parking in Old Oak Common, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot.
I let a flat near Willesden Junction station. Can you help?
Yes. We work for letting agents and landlords as well as householders. You can ring 0345 464 0079 or email us with the details for a clear quote.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference.
Can a leaking gutter joint be sealed?
Yes, as long as the gutter itself is in good order. We clean and dry the joint before sealing so the sealant bonds.
Should I try DIY first?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
How do I get a quote for gutter sealing in Old Oak Common?
We don’t publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Can you seal over the old sealant?
No. The old sealant always comes out first, so the new joint bonds to clean surfaces.
Do you replace gutters or fascias?
No, we reseal joints and trims. A gutter installer or roofer deals with replacement.
What we do, step by step
Most of a good job is in the preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes an hour or two for a few joints, longer for a full run. In Old Oak Common, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- We find where the water is coming from and check the gutter is sound.
- The old sealant and dirt are cleaned out of 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
- Mention any tricky access
- Plan for the work area to be out of bounds to pets and children
- For business premises, tell us about site rules or sign-in

Quotes for gutter sealing in Old Oak Common
We don’t publish a price list, because jobs vary so much. The quote depends on:
- The old material and how stubborn it is
- Any working-time requirements on site
- The product the joint needs
- Whether the work is at height
There are no prices on our website, because each job is priced on what it involves. Call for a quick quote.
What we need to know
There’s no need for technical detail. It helps if you can tell us:
- Where the property is
- The rough size of the job
- The type of property
- Any access issues, like height or stairs
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, phone 0345 464 0079 or send us an email.
Leave it or put it right?
New gutters cost far more than a few resealed joints. If the gutter is sound and the drip is a joint, resealing is the sensible fix. If it’s broken or sagging, a gutter installer needs to look. 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 Old Oak Common, the repair is bigger than the sealant job would have been.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re not sure whether it needs doing, ring 0345 464 0079 or drop us an email for an honest opinion and a quote.
