When to call us in Picket Piece
Age is the main cause. Sand mastic is a maintenance item like any pointing, depending on exposure and upkeep.
It’s worth asking for a quote if you see:
- Mastic round period door frames that has failed
- Modern sealant on a period surround
- Weathered mastic on the most exposed windows
- Mastic dropping out of the joint
Managing a site like Pilgrims' Cross CofE Aided Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages.
What to look for in a quote
- Whether you can choose the colour
- How much experience the applicator has
- What happens if they find a problem under the old sealant
- What preparation is included
Sand mastic for homes and businesses in Picket Piece
Our applicators renew the sand mastic around sash and case windows and doors in stone and brick. The old mastic is raked out, the joint is prepared and new mastic is shaped by hand. We work on tenement windows, brick reveals and sash and case windows, and the jobs we see most are mastic round period door frames that has failed and gaps where the frame meets the masonry.
Houses in smaller places like Picket Piece can stand more in the open than those in a built-up town. The mastic around frames on those walls tends to age faster.
All of our work is guaranteed for twelve months.

Sand mastic in Picket Piece: local notes
The South East is one of the drier parts 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 Andover station, cracked sand mastic around sash windows lets in the draughts tenants complain about.

Why deal with it now?
Silicone might seem the quicker option, but it can look wrong on a period surround. Sand mastic is the traditional material and finishes neatly against the masonry. In an older home around Picket Piece, damp from a failed joint can get into timber and plaster, and that’s a much bigger job than renewing the sealant.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
Why us?
- Full insurance on every job
- Anti-fungal silicone where joints get wet
- Tidy, careful work
- Quality sealants from Arbo and Everbuild
Take a look at our cost guide and customer reviews.
What affects the cost of sand mastic
We don’t publish a price list. What we look at:
- The product the joint needs
- Whether the work is at height
- Whether old sealant or filler has to be cut out
- Mould in or behind the old joints
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we’ll explain the quote if you ask.
Asking for a quote
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- What’s wrong with the joints now
- Where the property is
- Photos by email, if that’s easy
- The type of property
Getting a quote is simple: tell us what needs doing and where, and roughly how big it is. A few photos by email make the job easier to understand, and we’ll come back to you with a quote.
Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Clear gutters so water doesn’t pour onto the windows
- Take care around the mastic when scraping paint
- Have rotten timber repaired before new mastic goes in
- Don’t run silicone over sand mastic
Don’t touch or press the mastic while it hardens. It skins over quickly, but takes longer to harden fully.
Sound mastic protects the frame. Failed mastic lets water reach the timber and timber that stays wet can rot.
When it is not the sealant
We’d rather tell you now than do work that won’t last, so here’s what sealant cannot put right:
- Masonry that needs repairing
- Planning or listed building consent (your local planning authority decides)
- Broken panes
If in doubt, call 0345 464 0079 or email us and we’ll say what we think before booking.
What we seal
- Timber door frames
- Tenement windows
- Sash and case windows
- Period & listed homes
- Stone surrounds
- Brick reveals
Questions from Picket Piece
I let a flat near Andover station. Can you help?
Yes, we work for letting agents and landlords. You can call 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before we start.
Do you cover smaller places like Picket Piece?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Is it possible to take out silicone and use sand mastic instead?
Yes. We remove the silicone and clean the joint, then point it with sand mastic.
What should I tell you?
Just the basics: where it is, what you’ve noticed and how we reach it. Then call 0345 464 0079 or email us.
How long does the job take?
Most jobs take a few hours for a single window, longer for several, including preparation and clearing up. We will confirm how long when we quote.
Can you quote for more than one area?
Of course. Doing several areas at once is usually more efficient.
Is it worth trying it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
The process
On the day, we look over the joints with you first, so you know exactly what we are doing. Surfaces next to the work are protected before work begins. Most jobs take a few hours per window, depending on the condition of the joints. Parking around Picket Piece is usually easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- We start by checking each surround and agreeing the joints to renew.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The finish is dressed so it sits neatly against the stone or brick.
Getting ready for the visit
- Tell us about any previous sealing or DIY attempts
- Tell us if parking is tricky
- Try not to wet indoor joints just before the visit
