How we handle gutter sealing in Addlestone
Sealant only bonds to a clean, dry joint. So the old sealant and grime come out first and the joint is dried before the new sealant goes in. If you’re dealing with water dripping where gutter sections meet and streaks down the brickwork from a leaking joint, we can help, whatever the surface.
Outbuildings, garages and conservatories around homes in places like Addlestone add more joints to look after. Leaks normally start at a gutter end, a garage door frame or where an extension meets the house.
We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

When to call us in Addlestone
When a gutter sags, its joints open. Resealing a sagging joint will not last, so the gutter needs refixing first.
Keep an eye out for these signs:
- Rain getting in around a garage door
- Old sealant on roofline trims that has split
- End caps that drip every time it rains
- Water running down the wall below the gutter
For an older house near a landmark such as St Paul's, older walls, gutters and the joints where extensions meet them need a flexible sealant.

The process
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes an hour or two for a few joints, longer for a full run. A visit to Addlestone is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- First we trace the drip and check the gutter is not damaged.
- We remove the old sealant and clean the joint.
- The joint is dried before sealing.
- A gutter sealant is applied to the joint.
- We check the run and clear debris near the joints.
Before we arrive
- Mention if the joints have been sealed before
- Move anything stored near the joints
- On commercial sites, let us know about site rules

Addlestone buildings and the weather
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Botleys Mansion (about 1.8 miles west) are a reminder that the area around Addlestone has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
For site and facilities teams at buildings such as Darley Dene Primary School, its movement joints, gutters and trims need looking after like any other building’s. If you let a flat or house near Addlestone station, leaking gutter joints on a rental are best caught before they stain the walls.

DIY sealant or a professional job?
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.
Quotes for gutter sealing in Addlestone
We do not publish a price list, because no two jobs are the same. The quote depends on:
- Access and height
- Whether there’s mould to deal with
- When we can work, for business premises
- The old material and how stubborn it is
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
Helping us quote
To make quoting easier, please include:
- Where the job is, and your postcode
- Access, such as stairs, a lift or height
- How many joints, rooms or windows are involved
- What the problem is, such as mould, gaps, leaks or cracking
Asking for a quote is easy: let us know the job and the location. A few pictures by email make the job easier to understand, and we’ll come back to you with a quote.
Looking after it afterwards
To keep the joints looking good and working properly:
- Get a dropping gutter looked at quickly
- Get leaks sealed before the wet months
- Keep the gutters clear of debris
- Check the gutters during heavy rain
Clear the gutters once or twice a year so water doesn’t sit on the joints. Standing water strains every seal.
A leaking garage frame lets water reach stored items. Resealing the frame is a quick job.
Landlord and commercial work in Addlestone
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
If you manage several properties in or around Addlestone, jobs at different addresses can go on one quote. Just tell us the addresses and what each one needs.
What happens if it’s left?
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 has failed, we’ll tell you. Around Addlestone, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

Common questions in Addlestone
Do you cover smaller places like Addlestone?
Yes, Addlestone is covered. 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.

Is there any odour?
Some sealants have a smell while they cure. Ventilation helps.
Will you clear out my gutters?
We clear debris near the joints, so the sealant can bond. Cleaning the whole run is a separate job.
Do you offer different sealant colours?
Generally, yes. White, clear and grey are common, and other colours are available for many products, and we agree the colour with you before we start.
Do you work for hotels and businesses?
Yes. We have worked for hotels, offices and other businesses and we’re fully insured.
Can new sealant go over the old?
No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Will sealing fix a sagging gutter?
It won’t last. The joint will pull apart, so the fall and brackets need sorting first.
