About our gutter sealing in Windsor
A leaking gutter joint marks the wall and wets the ground underneath. Often a reseal is enough, as long as the gutter is sound. Typical jobs include wet patches on the wall under a gutter joint and water dripping where gutter sections meet, across gutter end caps, roofline trims and uPVC fascias.
Windsor mixes older houses and their gutters with newer estates of brick, render and uPVC trims. All of those joints move, so they need a flexible sealant rather than a rigid filler.
Our work is backed for twelve months.

Gutter sealing in Windsor: local notes
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as St Leonard's Hill (about 1 mile south-west) nearby, there’s older building stock in the area around Windsor as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
Letting a property close to Windsor & Eton Central station? Then a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking. Homes close to All Saints Church include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep.

What we’re called out for in Windsor
Water spilling over a blocked gutter is often mistaken for a leak. A blocked downpipe makes water back up, which is why we look before we seal.
If you can see any of these, it’s time to have the joints looked at:
- Dripping gutter ends
- Rain getting in around a garage door
- Open joints in fascias and soffits
- Streaks down the brickwork from a leaking joint
Managing a site like St Edward's Catholic First School? Then larger buildings have long runs of movement joint that eventually need resealing.

Common questions in Windsor
Is gutter sealing in Windsor guaranteed?
Every job comes with our 12-month guarantee, wherever it is. We are also fully insured and ARBOMaster approved.
Can you do gutter sealing in Windsor?
Yes. Our work covers London and the South East, and Windsor is part of that. Just phone 0345 464 0079 or send us an email with a few details of the job, and we will give you a clear quote.
Are you fully insured?
Yes. We are fully insured.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint before resealing.
Do I need to be at home?
It depends on the job. For work indoors, someone needs to let us in.
Can I do it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
What information do you need?
Just the basics: the address or postcode, what’s wrong and any access issues. After that, simply ring 0345 464 0079 or drop us an email.
Will you leave a mess?
Not at all. The area is protected while we work and cleaned up afterwards.

Can I do it myself?
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.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
What affects the quote in Windsor
We do not publish a price list, because no two jobs are the same. The quote depends on:
- The number of rooms or windows
- Whether there’s mould to deal with
- Whether the work is at height
- Whether old sealant or filler has to be cut out
Doing several joints on one visit normally makes better use of the time than several visits. You will get one clear quote for the whole job.
Helping us quote
Photos by email are helpful but not essential. Please mention:
- The address or postcode of the job
- The rough size of the job
- Any previous sealing or DIY work
- Whether it’s a home or a business

How the visit works
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take an hour or two for a few joints, longer for a full run. For a job in Windsor, we need access to where the work is and somewhere nearby to park. For outside work, let us know about side access, gates and any upper-floor joints.
- We start by tracing the leak and checking the gutter itself is sound.
- We clean out the joint and take out the old sealant.
- The joint is dried, because sealant won’t bond to a wet surface.
- An exterior or gutter sealant is applied to the joint.
- We check the run and clear any debris we find while we are there.
Preparing for the visit
- Let us know about parking restrictions
- Mention any leaks or damp you’ve noticed
- Let us know about stairs, lifts or work at height

Why it’s worth doing now in Windsor
A new garage door isn’t needed for a leaking frame. Sealing the frame generally stops it. Black mould and gaps in sealant do not fix themselves, and in a busy home in Windsor they get worse with every use. Replacing the sealant now is the simplest fix.
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
Why book with us
- Homes, businesses and hotels
- Any old sealant cut out fully, not covered over
- We agree the colour with you first
- 12-month guarantee on every job
