Gutter sealing in Kenley, done properly
A lot of gutter leaks come down to one tired joint. The joint is cleaned, dried and resealed using a gutter sealant. If the gutter itself has failed, we say so. We work on uPVC fascias, soffit joints and gutter joints, and people most often call us about open joints in fascias and soffits and water running down the wall below the gutter.
London’s terraces and conversions often share walls, gutters and downpipes with their neighbours, so one failed joint can cause damp for more than one household. In a converted house in Kenley, it’s worth checking who is responsible for the outside before booking.
Your job is guaranteed for a year, as with all our work.

What we do, step by step
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and tidy away. It usually takes an hour or two for a few joints, longer for a full run. In a London area like Kenley, 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 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 look along the gutter and clear debris around the joints.
Getting ready for the visit
- Clear the area around the work
- Mention any parking rules near the property
- Let us know about stairs, lifts or work at height

Walls and rooflines in Kenley
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. London terraces and converted houses often share gutters, downpipes and walls, so it’s worth agreeing who is responsible before work starts.
For landlords with property near Kenley station, a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking. If you live in an older home near Church of All Saints, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Your questions about gutter sealing in Kenley
Is parking a problem for a job in Kenley?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. The visit is then planned around what’s available.
Is Kenley in your area for gutter sealing?
Yes. We work across London and the South East, and Kenley is part of that. Just call 0345 464 0079 or send us an email with a few details of the job, and we will give you a clear price.
Can you seal fascia and soffit joints?
Yes. Our work is the joints, and if a board is damaged, we’ll tell you.
How long does the job take?
Typically it takes an hour or two for a few joints, longer for a full run. Bigger jobs take longer, and we’ll say how long yours will take.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. Our applicators cover Kenley.
Will there be a smell?
There can be a smell while the sealant cures, but it fades. Opening a window helps.
Will sealing fix a sagging gutter?
Not for long. The movement opens the joint again so the gutter has to be refixed first.
Will sealant fix a dripping gutter joint?
In most cases, yes. A sagging or cracked gutter needs more than sealant, and we’ll tell you.
Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
