Do you offer different sealant colours?
We’ll suggest a colour to suit the surroundings, from white and clear to greys and other shades. The choice depends on the product the joint needs.
Is it OK to seal over old sealant?
No, and we never do. It may look fine at first, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint before resealing.
Gutter sealing in London, done properly
It’s easy to live with a dripping gutter joint, but each shower sends water to the same place. Sealing it is quick while the gutter is still sound. We work on gutter joints, soffit joints and uPVC fascias, and people most often call us about old gutter sealant that has let go and internal damp traced to a gutter joint.
A place the size of London has buildings of every age, from older brick terraces to modern blocks with rendered or clad walls. Modern walls depend on their movement joints; older houses depend on sound gutter and roofline joints.
All of our work is guaranteed for twelve months, in London and everywhere else we cover.

Work for landlords, hotels and businesses
Hotels need rooms back in use, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
What happens if it’s left?
Leaving a leaking end cap can send water down the wall all winter. It’s a small job to put right before the damage spreads. In a large rental market like London, tired sealant leads to tenant complaints about mould, damp and leaks. Sorting it between tenancies is easier than dealing with it mid-let.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
Why London clients choose us
- Colour agreed with you before any work starts
- Any old sealant cut out fully, not covered over
- Every job guaranteed for a year
- We leave the area clean and tidy

Looking after it afterwards
Aftercare is simple:
- Keep an eye out for wet patches below a joint
- Look along the fascias for open joints
- Watch for drips in a downpour
- Keep the gutters clear of debris
Check the joints after heavy rain. Drips are easiest to spot while it’s raining.
If an end cap is dripping, deal with it before winter. A winter of drips can lead to damp patches inside.
What the job involves on each surface
Gutter end caps
We seal end caps from the inside where we can reach, after cleaning and drying.
Garage door frames
A fresh seal around the frame stops rain getting in.
When something else is needed
Before booking, it’s worth knowing the limits too:
- Downpipes that are blocked or broken
- Leaks from the roof rather than a joint

Walls and rooflines in London
Historic houses like Mansion House (about 1 mile north) are a reminder that the area around London has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. 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.
If you live in an older home near St George the Martyr, old and new materials meet at the roofline and walls, which is where sealant earns its keep. Managing a site like Charles Dickens Primary School? Then its movement joints, gutters and trims need looking after like any other building’s. Rented homes near Elephant & Castle station change hands often, and leaking gutter joints on a rental are best caught before they stain the walls.

Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
