External & façade joints in Hound Green, Hampshire
External mastic across Hound Green and nearby, with old sealant always removed completely.
- Cracked joints where brick meets render or frames
- Movement joints filled with mortar instead of sealant
- Moss and dirt in joints with no sealant left
DIY versus a professional finish
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
About our external mastic in Hound Green
Movement joints let brickwork, render and cladding expand and shrink without cracking. The sealant in it has to stretch and squeeze for years, so once it splits or hardens, the joint stops working and water gets in. We work on render & cladding joints, joints between brick and frames and façade panels, and the jobs we see most are rain getting behind render or cladding at a joint and weathered mastic that no longer stretches.
In a village or hamlet like Hound Green, older cottages and farm buildings often stand in the open, so walls and rooflines take the full force of wind and rain. Gutter joints and wall joints there need a sealant that can flex and stay put.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Hound Green: your questions answered
Will you come out to Hound Green?
Yes. Hound Green is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you cover Hound Green for external mastic?
Yes, Hound Green is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or send us an email and tell us what needs doing, and we will send you a clear quote.
How long does external mastic take?
Most jobs take a few hours for a handful of joints, longer for a whole elevation, including preparation and clearing up. We will confirm how long when we quote.
Are you fully insured?
Yes. Mr Mastic is fully insured, and we have been doing sealant work for more than 20 years.
Do I have to be there?
We need access to the joints, so we will agree that with you when we book. Indoors, that generally means someone at home.
Will the new joint stand out?
The sealant colour is picked to suit the wall. Exterior sealants come in a good range of colours.
Should I point up the gap in my brickwork?
No. Rigid materials cannot move with the wall, so the joint stops doing its job. If it has already been filled, we can generally cut it out and reseal it.
Can landlords and businesses book you?
Yes. We work for homeowners, landlords, letting agents, businesses and hotels across Hampshire.

Aftercare tips
Simple care keeps the joints in good condition. Our advice:
- Keep water from gutters off the wall
- Get split or bare joints resealed while the damage is small
- Look over the joints every year, ideally after winter
- Clear growth from the base of walls and joints
Look over the joints once a year, ideally after winter. Watch for splits, edges coming away or growth in the joint.
Small splits are the time to act. At that stage it’s a simple cut out and reseal.
External mastic in Hound Green: local notes
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Stratfield Saye House (about 2.4 miles north-west) nearby, there’s older building stock in the area around Hound Green 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.
Letting a property close to Hook station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies. If you live in an older home near Mattingley Church, older walls, gutters and the joints where extensions meet them need a flexible sealant.

Different surfaces, different methods
Cladding and façade panels
Panels heat up and cool down quickly, so the joint sealant has to cope with frequent movement. We choose the product to suit.
Brickwork movement joints
Vertical joints in long brick walls let the brickwork expand without cracking. They’re resealed over backing rod with a low-modulus sealant coloured to suit the wall.
When it isn’t the sealant
We’ll always be straight with you, so here’s what new sealant won’t do:
- Movement that’s more than a sealant joint can take
- Adding movement joints to masonry that has none
- Failed render or damaged cladding panels
If you’re not sure, just ring 0345 464 0079 or drop us an email and we will give you a straight answer before you book.
What we seal
- Copings & trims
- Concrete & block
- Joints between brick and frames

Why act early in Hound Green
Done well, a resealed joint is a neat, straight line that suits the wall. A rushed bead with no backing looks untidy and does not last, so it pays to do it properly once. In a small place like Hound Green, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part.
