Walls and rooflines in Nash
With historic houses such as Down House (about 2.4 miles south-east) nearby, there’s older building stock in the area around Nash as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. London terraces and converted houses often share gutters, downpipes and walls, so it’s worth agreeing who is responsible before work starts.
As a London address, Nash can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. In the older streets around Keston Parish Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

How we handle gutter sealing in Nash
Gutter and fascia replacement is not our trade, and nor is roofing. What sealant does is close joints; it will not fix a broken bracket, a cracked section or a blocked downpipe. Typical jobs include wet patches on the wall under a gutter joint and garage door frames letting rain in, on soffit joints, garage door frames and gutter joints.
Outside work in London starts with access: side passages, upper floors and where to park. In Nash, joints up high may need ladders or other access, which is worth talking through when you book.
Each job carries a 12-month guarantee.

What else we do in Nash
Nash: your questions answered
Do you cover Nash for gutter sealing?
Yes, Nash is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or email us with a few details of the job.
Is parking a problem for a job in Nash?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.
Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us.
Is sealant enough for a gutter that has dropped?
Not for long. The movement opens the joint again so the gutter has to be refixed first.
Will you leave a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
How long will you be here?
As a guide, most jobs take anything from an hour or two to a few hours. Bigger jobs take longer, and we’ll tell you how long to expect.
Is the work guaranteed?
There’s a 12-month guarantee on every job, gutter and fascia work included.
Do you work for landlords and businesses?
Yes, often. Several properties can go on one quote.
Why it’s worth doing now in Nash
Leaving a leaking end cap can send water down the wall all winter. It’s a small job to put right compared with treating damp later. In a flat in Nash, failed sealant seldom stays inside your own four walls: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote and we will talk you through it.
Why book with us
- More than 20 years in sealant work
- Homes, businesses and hotels
- An ARBOMaster approved applicator
- Any old sealant cut out fully, not covered over
Take a look at what affects the cost and our reviews.
Do you need gutter sealing in Nash?
Roofline sealant ages in sun and rain. It goes hard, cracks and pulls away after some years.
If you can see any of these, it’s time to have the joints looked at:
- Damp on an inside wall under a dripping gutter
- Stop ends leaking at the end of a run
- Earlier gutter repairs that have peeled off
- Water dripping where gutter sections meet
Letting a property close to Hayes (Kent) station? Then a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking.
Before you book anyone
- Are they insured?
- How the colour is chosen

Doing several joints on one visit normally makes better use of the time than several visits. We’ll give you a clear price for the lot.

What the job involves on each surface
Gutter joints
When a joint drips, the gutter is often still sound. Sealing the joint often stops it.
uPVC fascias
Joints between fascia boards can open over time. We seal them neatly with a matching sealant where possible.
Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Keep ladders off the guttering
- Do not leave a sagging gutter
- Keep downpipes clear
- Look at the gutters while it’s raining
Give the sealant the cure time we tell you before poking or cleaning near it.
The sooner a gutter leak is sealed, the less water reaches the wall. If we find a bigger problem, we’ll tell you.
DIY versus a professional finish
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What we do, step by step
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The work itself takes a few hours, depending on the number of joints and the access from start to finish. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. Mention any building rules, key holders or managing agents when you book.
- We start by tracing the leak and checking the gutter itself is sound.
- 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 look along the gutter and clear debris around the joints.
How to prepare
- Tell us about any water getting in
- Mention if the joints have been sealed before
- Mention any tricky access
