Thames Ditton: your questions answered
Is Thames Ditton within the area you cover?
Yes, Thames Ditton is covered. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
I let a flat near Thames Ditton station. Can you help?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before any work starts.
Can new sealant go over the old?
No. The old sealant always comes out first.
Will the old sealant be removed?
Yes, always, and completely. New sealant will not bond properly to old, so the joint is cleaned back first.
Do I have to be there?
It depends on the job. Inside work needs someone to give us access.
Do you install new fascias or gutters?
That is not something we do. We seal joints; replacing gutters and fascias needs a gutter or roofline installer.
Where are you based?
We’re a Crawley-based firm. Our area covers South East England, London and Scotland.
Can you match the sealant colour?
Most of the time, yes. We’ll explain which colours are available.
About our gutter sealing in Thames Ditton
Across Thames Ditton, we reseal gutter joints, end caps and roofline trims. Single-storey and low gutters are simple to reach, and for higher work, tell us about access and we’ll confirm what’s needed. Common call-outs are for dripping gutter ends and water running down the wall below the gutter, across soffit joints, gutter joints and gutter end caps.
Outbuildings, garages and conservatories around homes in places like Thames Ditton add more joints to look after. Leaks normally start at a gutter end, a garage door frame or where an extension meets the house.
You’re covered for a year from the day we finish. If there’s a problem with it, please phone 0345 464 0079 or drop us an email.

Why act early in Thames Ditton
You do not need to replace a garage door because rain gets in round the frame. Resealing the frame joint is often enough. Homes in smaller places like Thames Ditton can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
What you pay reflects the work, not a rough estimate. That is why we ask about the job first and send you a clear quote before we start.

What affects the cost of gutter sealing
We quote each job individually. These are the things that affect it:
- The number of rooms or windows
- The size of the job
- Which sealant suits the joint
- How easy the joints are to reach
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re unsure, call 0345 464 0079 or send us an email and we will give you an honest view and a quote.

How the visit works
All our tools and materials come with us in the van. Once we have agreed what’s being done, we protect the area and start. It normally takes a few hours, depending on the number of joints and the access. Parking around Thames Ditton is normally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- We start by tracing the leak and checking the gutter itself is sound.
- We clean out the joint and take out the old sealant.
- We make sure the joint is dry before sealing.
- Gutter or exterior sealant is applied and finished.
- We look along the gutter and clear debris around the joints.
Preparing for the visit
- Mention any parking rules near the property
- Mention any leaks or damp you’ve noticed
- Mention if the joints have been sealed before

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Glance at the soffit joints now and then
- Get a dropping gutter looked at quickly
- Clean out the gutters once or twice a year
- Keep an eye out for wet patches below a joint
Keep downpipes clear so the gutter can drain. A blocked pipe backs water up to the joints.
If an end cap is dripping, deal with it before winter. Water down the wall all winter can cause damp inside.
DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

Thames Ditton buildings and the weather
Historic houses like Hampton Court Palace (about 1 mile north) are a reminder that the area around Thames Ditton 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. 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.
For site and facilities teams at buildings such as Thames Ditton Junior School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. For an older house near a landmark such as Church of St. Nicholas, older walls, gutters and the joints where extensions meet them need a flexible sealant.
