Gutter sealing for homes and businesses in Eltham
A drip at a gutter joint is easy to ignore, but each shower sends water to the same place. Resealing it is a small job while the gutter is still sound. We work on roofline trims, gutter joints and soffit joints, and people most often call us about old sealant on roofline trims that has split and failed sealant on a garage door frame.
In London terraces and converted houses, gutters and walls are often shared with the house next door, so one failed joint can cause damp for more than one household. In a converted house in Eltham, it’s worth checking who is responsible for the outside before booking.
Each job carries a 12-month guarantee, whatever its size.

What we can’t put right
We’d rather tell you now than do work that will not last, so these are the limits:
- Guttering that needs replacing
- Downpipes that are blocked or broken
- Gutters that have dropped or pulled away
If in doubt, ring 0345 464 0079 or drop us an email and we will say what we think before you book.
What we seal
- uPVC fascias
- Gutter end caps
- Soffit joints
- Roofline trims
- Gutter joints
- Garage door frames
Why deal with it now?
You do not need new fascias just because the joints have opened. A neat seal closes the gaps if the boards are sound. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and by the time it shows on a wall or ceiling in Eltham, the repair is bigger than the sealant job would have been.
What you pay reflects the work, not a rough estimate. That’s why we ask about the job first and send you a clear quote before we start.

Walls and rooflines in Eltham
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. With historic houses such as Eltham Palace (about 0.4 miles north-west) nearby, there’s older building stock in the area around Eltham as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
If you live in an older home near Church of Holy Trinity, older walls, gutters and the joints where extensions meet them need a flexible sealant. Eltham is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

When to call us in Eltham
Gutter joints depend on seals that wear out. Temperature changes make gutters move and that movement opens up tired joints.
Signs it’s time to call us include:
- Old gutter sealant that has let go
- Garage door frames letting rain in
- Trim joints where the sealant has failed
- Leaking gutter joints and stop ends
Schools such as St Thomas More Catholic Comprehensive School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

How it works
When we arrive, we start by going over the job with you. We protect the surfaces around the joints before any work begins. Most jobs take an hour or two for a few joints, longer for a full run. In a London area like Eltham, the main things to plan are parking and access: let us know about parking, the floor we’ll be working on and any lift or shared entrance.
- We look at where the water is coming from and check the gutter is not broken or sagging.
- Old sealant and dirt are removed from the joint.
- 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’re there.
Getting ready for the visit
- Keep pets and children clear of the area while we work
- Tell us about access, such as stairs, a lift or high-level joints
- Clear items away from the joints we’re working on

Advice
Questions from Eltham
Do you cover Eltham for gutter sealing?
Yes. We work across London and the South East, and Eltham is part of that. Just ring 0345 464 0079 or send us an email with a few details of the job.
Can you help a landlord with a rental near Mottingham station?
Yes. We work for landlords and letting agents as well as homeowners. Just call 0345 464 0079 or email us with the address and what needs doing, and we will send you a clear quote.
Do you replace gutters or fascias?
We don’t replace gutters or fascias. We’ll tell you if the gutter needs replacing so you can call the right trade.
What sealant do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference.
Do you offer different sealant colours?
In most cases you can choose. We’ll tell you which colours the right product comes in and agree one before any work starts.
Is it messy?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Will sealing fix a sagging gutter?
Sealant will not hold a sagging gutter. A gutter installer needs to refix it.
What about gutters on a second or third storey?
It depends on the access. Let us know the height and the ground below when you ring 0345 464 0079 or email us.
Should I try it myself first?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
