Gutter Sealing in Locks Heath
Gutter and fascia joints in Locks Heath need attention? We cut out the old, prepare the joints and apply the right sealant.
- Streaks down the brickwork from a leaking joint
- Garage door frames letting rain in
- Trim joints where the sealant has failed
What we’re called out for in Locks Heath
Leaves and moss hold water in the gutter. Water that can’t drain works its way through a weak joint and drips through.
Signs it’s time to call us include:
- Cracked sealant along roofline trims
- Failed sealant on a garage door frame
- Earlier gutter repairs that have peeled off
- Gaps along fascia and soffit joints
If you look after a building such as Park Gate Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Gutter sealing in Locks Heath
A leaking gutter joint marks the wall and wets the ground underneath. Resealing the joint is often all it needs, as long as the gutter is sound. We work on roofline trims, gutter end caps and garage door frames, and people most often call us about leaking gutter joints and stop ends and dripping gutter ends.
Around Locks Heath, garages, outbuildings and extensions all add to the joints on the outside of a home. Leaks usually start at a gutter end, a garage door frame or where an extension meets the house.
There’s a 12-month guarantee on every job, large or small.

Questions from Locks Heath
I let a flat near Swanwick station. Can you help?
Yes, rental work is part of what we do. Just call 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear price.
Do you cover smaller places like Locks Heath?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
How long should I leave it?
It depends on the product and the temperature. We tell you how long to leave it before we go.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status and we are fully insured too.
Where are you based?
We’re based in Crawley, and we work across South East England, London and Scotland.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
What information do you need?
Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.
Do you have insurance?
Yes. Mr Mastic is fully insured, and we’ve been doing sealant work for more than 20 years.
Keeping the joints in good condition
A little care helps the new joints last. We recommend:
- Watch for drips in a downpour
- Keep the gutters clear of debris
- Look for streaks or damp on the wall below gutters
- Deal with a drip before winter
Keep downpipes clear, so water can get away. A blocked pipe backs water up to the joints.
A drip from a gutter joint won’t stop on its own. Water keeps hitting the same part of the wall and that can cause damp inside.
Locks Heath buildings and the weather
Locks Heath is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on gutter, fascia and roofline joints, especially on the side facing the sea. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you let a flat or house near Swanwick station, a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside. In the older streets around St John, an extension built onto an older house moves differently, and the joint between them takes the strain.

How we quote for gutter sealing
Call for a quick quote. What matters most is:
- Whether there’s mould to deal with
- Any working-time requirements on site
- The size of the job
- The number of rooms or windows
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Asking for a quote
What to tell us when you ask for a quote:
- Any previous sealing or DIY work
- Pictures of the joints, sent by email
- The address or postcode of the job
- The type of property
We don’t publish a price list. Instead, your job gets its own clear quote. To get started, call 0345 464 0079 or send us an email.
What happens if it’s left?
Leaving a leaking end cap can send water down the wall all winter. Resealing it is a quick job before the damage spreads. Around Locks Heath, water from a failed joint in an older home can soak into timber and plaster, and that’s a much bigger job than renewing the sealant.
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first.
