Hatch End Gutter Sealing
Problem with your gutter and fascia joints in Hatch End? We cut out the old, prepare the joints and apply the right sealant, and the work is guaranteed for a year.
- Failed sealant on a garage door frame
- Leaking gutter joints and stop ends
- Wet patches on the wall under a gutter joint
What we’re called out for in Hatch End
Leaves and moss hold water in the gutter. Standing water finds the weakest joint and leaks out.
If you can see any of these, it’s time to have the joints looked at:
- Leaking gutter joints and stop ends
- Damp patches inside below a leaking gutter
- Old gutter sealant that has let go
- Open joints in fascias and soffits
If you let a flat or house near Hatch End station, a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside.

Gutter sealing for homes and businesses in Hatch End
A leaking gutter joint marks the wall and wets the ground underneath. Resealing the joint is often all it needs if the gutter isn’t damaged. We work on uPVC fascias, gutter end caps and roofline trims, and people most often call us about quick sealant fixes on gutters that didn’t last and wet patches on the wall under a gutter joint.
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 Hatch End, it’s worth checking who is responsible for the outside before booking.
Our work is backed for twelve months.

Outside joints around Hatch End
London terraces and converted houses often share gutters, downpipes and walls, so check who is responsible for the outside before booking. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
As a London address, Hatch End can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. Homes close to Pinner Baptist Church include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move.

Looking after it afterwards
A little care helps the new joints last. We recommend:
- Clear leaves and moss from the gutters
- Do not lean ladders against the gutter itself
- Look at the gutters while it’s raining
- Sort out a dripping joint early
While checking gutters, glance at the fascia joints too. A small split is quicker to put right.
A leaking garage frame lets water reach stored items. Resealing the frame is a quick job.
What happens on the day
All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. Once we’ve agreed what’s being done, the area is protected and the work begins. Most jobs take anything from an hour or two to a few hours. In Hatch End, as in most of London, parking needs a little planning. It helps if you can point us to a visitor permit or a bay close to the door.
- We find where the water is coming from and check the gutter is sound.
- We remove the old sealant and clean the joint.
- We dry the joint so the new sealant can bond.
- A gutter sealant is applied to the joint.
- We check the run and clear debris near the joints.
Preparing for the visit
- Move anything stored near the joints
- Tell us about any water getting in
- Keep pets and children clear of the area while we work

How we quote for gutter sealing
Your quote is based on your job. We take into account:
- Whether the work is at height
- Working hours on commercial sites
- The old material and how stubborn it is
- The size of the job
What it costs depends on how much there is to do, how hard the old material is to remove and access to the work. We give a clear quote before we start.
What to tell us for a quote
To make quoting easier, please include:
- Where the property is
- Whether it has been sealed before
- A few photos by email, if you can
- How we’d reach the joints
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and email photos if that’s easy.
Can I do it myself?
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.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Hatch End: your questions answered
Can you do gutter sealing in Hatch End?
Yes, Hatch End is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or drop us an email and tell us what needs doing, and we’ll send you a clear quote.
Is parking a problem for a job in Hatch End?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly.
Can a leaking gutter joint be sealed?
In most cases, yes. If the gutter is sagging or cracked, sealing won’t last and we’ll say so.
How long does gutter sealing take?
Typically it takes a few hours, depending on the number of joints and the access. Bigger jobs take longer, and we’ll tell you how long to expect.
Can I choose the sealant colour?
We help you choose a colour that suits, from white and clear to greys and other shades. The product needed can limit the range.
Where is Mr Mastic based?
We’re based in Crawley, and we work across South East England, London and Scotland.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint.
Do you clean gutters?
Only around the joints we seal, so the sealant can bond. A full gutter clean is a separate job.
Leave it or put it right?
A new garage door isn’t needed for a leaking frame. Sealing the frame normally stops it, if the frame itself is sound. In London conversions, one flat’s bathroom is often above another flat’s ceiling, and a slow leak from a failed seal can end up in the flat below. Dealing with it early is far simpler for homes in Hatch End.
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs. Ask us for a quote and we will go through it with you.
