External mastic in Picket Piece
External mastic is a job where short cuts show quickly. Overfilled joints, missing backing rod and sealant laid over old sealant rarely last long. We take the old material out and do it properly. We work on façade panels, joints between brick and frames and render & cladding joints, and the jobs we see most are gaps where render, brick and frames meet and leaking joints around cladding and façade panels.
In and around Picket Piece, older properties sit alongside newer ones, each with its own outside joints. Older homes need their gutter and trim joints kept tight, newer ones their movement joints.
Big or small, you get the same one-year guarantee in Picket Piece and across Hampshire.

Common problems we fix in Picket Piece
Buildings move more than people expect. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. All of that ends up in the joint sealant.
If you can see any of these, it’s time to have the joints looked at:
- Rain getting behind render or cladding at a joint
- Movement joints with cracked, split or missing sealant
- Moss and dirt in joints with no sealant left
- Joints where the bead has come unstuck
Managing a site like Pilgrims' Cross CofE Aided Primary School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
Questions to ask before you book
- What happens if the job turns out different
- Whether you can choose the colour
- How long the guarantee is
- Who does the work, and how experienced they are
What sealant work can’t fix
Some problems need a builder, plumber or other trade rather than us:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Damp that isn’t coming from the joint
- Cracking across the wall rather than at a joint
If you’re not sure, just call 0345 464 0079 or email us and we will give you a straight answer before booking.

The process
A visit follows a simple pattern: we look at the joints together, protect the area around them, do the work and tidy away. It normally takes a few hours to a few days, depending on the length of joint and the access. A visit to Picket Piece is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- Backing rod goes in so the sealant can stretch between the two faces.
- We prime the faces where required.
- We gun in low-modulus sealant and tool it neatly.
How to prepare
- Keep pets and children clear of the area while we work
- Mention any tricky access
- Tell us about any previous sealing or DIY attempts

Can I do it myself?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
Aftercare tips
Good habits help new joints last longer. A few tips:
- Check the sealant is paintable before painting near it
- Look over the joints every year, ideally after winter
- Deal with leaking gutters that soak the joints below
- Keep high-pressure jets off the joints
Only paint over the joint if we have confirmed the sealant can take paint. Paint can crack on a flexible joint and spoil the finish.
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 the job involves on each surface
Concrete and blockwork
Concrete faces can be dusty and porous, so cleaning and priming matter. We prime where the sealant needs it before sealing.
Render joints
Render is weaker at the surface than brick, so a sealant that stretches easily protects the edges. We prime where the product needs it.
FAQs for Picket Piece
Is Picket Piece in your area for external mastic?
Yes. We work across London and the South East, and Picket Piece is part of that. Just phone 0345 464 0079 or email us with a few details of the job.
Can you help a landlord with a rental near Andover station?
Yes, landlords and agents are among the people we work for. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
Do you have insurance?
Yes. We’re fully insured for domestic and commercial work.
Do you use backing rod?
Backing rod controls the sealant depth and keeps it off the back of the joint. That way it bonds to the two sides only and can stretch.
When will the joints need doing again?
That varies with the weather the wall faces, how much it moves and the sealant used. Sealant is a maintenance item, so check the joints once a year and renew it when it starts to fail.
When is the sealant fully cured?
It depends on the product. We tell you how long to leave it before we go.
What is a movement joint?
A vertical gap in a long brick wall is generally a movement joint. It gives the wall room to move, and it should be sealed with a flexible sealant.
Can I add another job to the visit?
Of course. Combining jobs makes good use of the visit.
