Hiltingbury External Mastic
External mastic across Hiltingbury and nearby, with old sealant always removed completely and a 12-month guarantee.
- Moss and dirt in joints with no sealant left
- Water getting into walls through failed joints
- Sealant that has lost its bond to the brick or render
How we handle external mastic in Hiltingbury
Failed sealant is cut out, the depth set with closed-cell backing rod, and the joint resealed with a low-modulus sealant made for outside. The colour is chosen to suit the brick or render so the joint does not stand out. If you are dealing with joints pointed up with cement by mistake and gaps where render, brick and frames meet, we can put it right, whatever the surface.
Around Hiltingbury, garages, outbuildings and extensions all add to the joints on the outside of a home. Gutter ends, garage door frames and the joints where an extension meets the house are typical spots for leaks.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

How the visit works
Most of a good job is in the preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. In total, it normally takes a few hours for a handful of joints, longer for a whole elevation. In a smaller place like Hiltingbury, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
Before we arrive
- Mention any leaks or damp you’ve noticed
- Let us know about parking restrictions
- Tell us about any previous sealing or DIY attempts

Can I do it myself?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Honest limits
Sealant is not the answer to every problem, and we’ll tell you before any work starts. Sealant won’t put right:
- Loose or hollow render, which needs re-rendering
- Cracks in the bricks or render themselves, away from the joints
- Cutting new joints into brickwork, which is building work rather than sealant work
If in doubt, ring 0345 464 0079 or send us an email and we will say what we think before booking.
Surfaces we seal
- Copings & trims
- Render & cladding joints
- Façade panels
- Brickwork movement joints
- Concrete & block
- Joints between brick and frames
Different surfaces, different methods
Copings and trims
Metal and stone copings both move with temperature, so a flexible sealant suits them best in all weathers.
Cladding and façade panels
Panel systems often rely on sealant between and around the panels. Each joint gets a sealant that suits the panel and its movement.
Looking after it afterwards
A little care helps the new joints last. We recommend:
- Ask before painting over external sealant
- Keep soil, plants and ivy away from the joints
- Show decorators and builders where the movement joints are
- Have failed joints looked at early
Keep pressure washers away from the sealant. A strong jet can damage the edges of the bead.
If you can see gaps, plants or bare sections in a joint, have it checked. Earlier resealing means a smaller job and a better result.
What we are called out for in Hiltingbury
Sunlight, wet weather and frost wear exterior sealant down. In time it goes hard, crazes on the surface and stops stretching, so the next time the wall moves, it splits or pulls away.
Signs it’s time to call us include:
- Panel joints letting water in
- Moss and dirt in joints with no sealant left
- Movement joints with cracked, split or missing sealant
- Sealant pulling away from one side of the joint
Schools such as Hiltingbury Junior School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
What your quote should include
- How hidden problems are handled
- Whether the sealant suits the joint
- Are they insured?

What external mastic looks like in Hiltingbury
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. With historic houses such as South Stoneham House (about 4.3 miles south) nearby, there’s older building stock in the area around Hiltingbury as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
Homes close to St. Martin in the Woods include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain. Rented homes near Chandlers Ford station change hands often, and split movement joints are easy to miss on a rental until damp shows inside.

Your questions about external mastic in Hiltingbury
Do you cover smaller places like Hiltingbury?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
I let a flat near Chandlers Ford station. Can you help?
Yes, we work for landlords and agents. You can phone 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before work begins.
Do you do commercial work?
Yes, regularly. We can plan bigger jobs in stages.
Can you reach joints on upper floors?
It depends on the building. Send us pictures and a rough idea of the height, and we’ll confirm what access is needed.
What colours does the sealant come in?
The sealant colour is picked to suit the wall, so the joint sits quietly in the wall. There’s a wide choice of exterior colours.
Do I have to be there?
We need access to the joints, so we will agree that with you when we book. Indoors, that normally means someone at home.
How often do external joints need resealing?
It varies with how exposed the wall is and how much the joint moves. Look for splits, hardening or edges coming away and have them redone then.
Where is Mr Mastic based?
We work from Crawley. Our applicators cover Hiltingbury, along with the rest of our area.
