How we handle gutter sealing in Charlton
It’s easy to live with a dripping gutter joint, but the water lands on the same spot every time it rains. Resealing it is a small job if the gutter is otherwise in good order. Common call-outs are for quick sealant fixes on gutters that didn’t last and damp patches inside below a leaking gutter, on gutter end caps, uPVC fascias and garage door frames.
External sealant needs dry, clean surfaces, so work around Charlton is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.

FAQs for Charlton
Is Charlton in your area for gutter sealing?
Yes. Our work covers London and the South East, and Charlton is part of that. You can phone 0345 464 0079 or drop us an email and let us know what needs doing, and we will give you a clear quote.
Do you cover smaller places like Charlton?
Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
What about gutters on a second or third storey?
That depends on the building. Let us know the height and the ground below and we’ll confirm what’s needed.
Do you have insurance?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Should I try DIY first?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Is sealing fascia joints something you do?
Yes. Our work is the joints and we’ll let you know if a board has failed.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you do not need to watch us work.
Is it possible to stop a gutter joint dripping with sealant?
In many cases, yes. A clean, dry joint resealed with gutter sealant usually stops the drip. A split or warped section needs replacing.
Work for landlords, hotels and businesses
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
How we quote for gutter sealing

- Working hours on commercial sites
- Any mould that needs treating
- Whether old sealant or filler has to be cut out

Combining jobs into one visit is normally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We will give you a clear quote for the lot.
What we need to know
What to tell us when you ask for a quote:
- Any previous sealing or DIY work
- How many joints, rooms or windows are involved
- The address or postcode of the job
- Whether it’s a home or a business
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. Whenever you are ready, ring 0345 464 0079 or send us an email.
Charlton buildings and the weather
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Hampton Court Palace (about 4.6 miles east) are a reminder that the area around Charlton has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
For landlords with property near Upper Halliford station, a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking. For an older house near a landmark such as Church of St Mary Magdalene, the joints between older walls, newer extensions and the roofline need a sealant that can move. For site and facilities teams at buildings such as Littleton CofE Infant School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Aftercare tips
To keep the joints looking good and working properly:
- Make sure downpipes are not blocked
- Deal with a drip before winter
- Clear leaves and moss from the gutters
- Don’t leave a sagging gutter
Look at fascia and trim joints when you are checking the gutters. A small split is quicker to put right.
The sooner a gutter leak is sealed, the less water reaches the wall. If we find a bigger problem, we will tell you.
How it works
Good joint work is mostly preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes an hour or two for a few joints, longer for a full run. In a small place like Charlton, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
- We seal the joint with a sealant made for gutters.
- The gutter is checked and debris around the joints cleared.
Before we arrive
- Move anything stored near the joints
- Keep pets and children clear of the area while we work
- For indoor joints, keep the area dry beforehand if you can

What happens if it’s left?
A bead squeezed onto a wet joint might hold for a while but it tends to peel off. Proper preparation is the difference. Where a wall is exposed, as many are in small places like Charlton, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs. Call for a quick quote and we will explain what it covers.
