Gutter sealing for homes and businesses in Waterdale
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. We work on garage door frames, roofline trims and uPVC fascias, and the jobs we see most are rain getting in around a garage door and streaks down the brickwork from a leaking joint.
Older homes in small places like Waterdale may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water usually gets in.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

FAQs for Waterdale
I let a flat near Bricket Wood station. Can you help?
Yes, rental work is part of what we do. Just call 0345 464 0079 or drop us an email and tell us about the property, and we’ll send you a clear quote.
Is Waterdale in your area for gutter sealing?
Yes. We work across London and the South East, and Waterdale is part of that. You can phone 0345 464 0079 or drop us an email and let us know what needs doing, and we’ll give you a clear price.
Is gutter cleaning part of the job?
Only around the joints we seal because the joint must be clean. Cleaning the whole run is a separate job.
Will sealing fix a sagging gutter?
Not on its own. A sagging gutter pulls its joints apart so it needs refixing before sealing.
Is the work guaranteed?
Every job comes with our 12-month guarantee, and we’re fully insured.
Do you take out the old sealant first?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
How long should I leave it?
It depends on the product and the conditions. We tell you how long to leave it before we go.
How long does the job take?
It depends on the size of the job, but as a guide it takes anything from an hour or two to a few hours. We’ll give you a better idea when we quote.
Outside joints around Waterdale
Historic houses like High Elms Manor (about 0.5 miles south-west) are a reminder that the area around Waterdale has older buildings as well as new. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Rented homes near Bricket Wood station change hands often, and leaking gutter joints on a rental are best caught before they stain the walls. For site and facilities teams at buildings such as Parmiter's School, larger buildings have long runs of movement joint that eventually need resealing.

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.
Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.
How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Look along the fascias for open joints
- Don’t lean ladders against the gutter itself
- Get a dropping gutter looked at quickly
- Check that water runs out of the downpipes
A sagging gutter needs its brackets checked. If it drops, the joints will open.
Leaking gutter joints get worse over time. Water keeps hitting the same part of the wall and that can cause damp inside.
What the job involves on each surface
uPVC fascias
Gaps in fascias spoil the roofline. A neat bead closes them up.
Soffit joints
Soffit joints are sealed in a colour to suit, where one is available.
How we quote for gutter sealing
The price is agreed before any work begins. It takes into account:
- The old material and how stubborn it is
- Whether the work is at height
- When we can work, for business premises
- The number of rooms or windows
Doing several joints on one visit usually makes better use of the time than several visits. We will send you a clear quote for the lot.
What we need to know
There’s no need for technical detail. Just tell us:
- How many joints, rooms or windows are involved
- What the problem is, such as mould, gaps, leaks or cracking
- The address or postcode of the job
- Any previous sealing or DIY work

What we are called out for in Waterdale
End caps get knocked or pushed by water. If the seal fails, water escapes at the end and runs down the wall.
These are the problems we are asked about most:
- Leaking gutter joints and stop ends
- Old sealant on roofline trims that has split
- Dripping gutter ends
- Streaks down the brickwork from a leaking joint
In the older streets around Church of All Saints, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Sealant is not the answer to every problem, and we will tell you before any work starts. It won’t solve:
- Guttering that needs replacing
- Leaks from the roof rather than a joint
- Downpipes that are blocked or broken
If you’re not sure, just call 0345 464 0079 or drop us an email and we will give you a straight answer before you book.

How it works
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes a few hours, depending on the number of joints and the access and we leave things clean and tidy. Somewhere like Waterdale needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We start by tracing the leak and checking the gutter itself is sound.
- The joint or trim is cleaned out and old sealant removed.
- The area is dried so the sealant can bond.
- 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
- Tell us if parking is tricky
- Try not to wet indoor joints just before the visit
- Mention any leaks or damp you’ve noticed
