Sand mastic for sash & case windows in Pixham, Surrey
Professional sand mastic in and around Pixham, with every bit of old sealant taken out first.
- Cracked mastic round a front door frame
- Wind and rain getting in round a sash window
- Cement or filler used on old window joints that has cracked
Why deal with it now?
New mastic over crumbling mastic will not hold. We remove the loose material first so the new mastic stays put. Around Pixham, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are unsure, phone 0345 464 0079 or send us an email for an honest opinion and a quote.

About our sand mastic in Pixham
Our applicators renew the sand mastic around sash and case windows and doors set in stone or brick. The old mastic is raked out, and new mastic is applied and shaped by hand. We work on timber door frames, period & listed homes and sash and case windows, and common reasons people get in touch are gaps between timber frames and stone or brick and cement or filler used on old window joints that has cracked.
Homes in small places like Pixham often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Your questions about sand mastic in Pixham
Is Pixham in your area for sand mastic?
Yes. Our work covers London and the South East, and Pixham is part of that. You can ring 0345 464 0079 or drop us an email and let us know what needs doing.
Can you help a landlord with a rental near Dorking station?
Yes. We work for landlords and letting agents as well as homeowners. Just call 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear quote.
Do you take out the old sealant first?
Yes, every time. New sealant won’t bond properly to old, so the joint is cleaned back first.
Which is right for my windows, sand mastic or modern sealant?
It depends on the window. Period windows in stone or brick usually suit sand mastic, while modern frames normally get a flexible sealant.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Can you replace silicone on a period window with sand mastic?
Often, yes. With the silicone removed and the joint cleaned we point it with sand mastic.
Will there be a smell?
There can be a smell while the sealant cures, but it fades. Ventilation helps.
Do I need permission for sand mastic on a listed building?
Yes, it’s worth checking. Your local planning authority can say if consent is needed for listed or conservation-area properties.
Do you need sand mastic in Pixham?
Age is the main cause. Even well-laid mastic needs renewing in time, depending on exposure and upkeep.
If you can see any of these, it’s time to have the joints looked at:
- Failed mastic on an exposed elevation
- Window mastic to renew ahead of painting
- Draughts and rain around sash boxes
- A silicone bead on a sash window that spoils the look
If you look after a building such as The Ashcombe School, the mastic around its windows and doors needs looking after like any other building’s.

When it is not the sealant
To be straight with you, there are a few things sealant won’t fix:
- Crumbling stone or brickwork round the window
- Timber that has rotted
- Sash cords, weights and draught-proofing of the sashes
If you’re not sure, just ring 0345 464 0079 or drop us an email and we will give you a straight answer.

The process
Before we leave, we go over the finished joints with you. The visit itself normally takes a few hours per window, depending on the condition of the joints, depending on the amount of work. In a small place like Pixham, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check the window surrounds and agree which joints need renewing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The finish is dressed so it sits neatly against the stone or brick.
Before we arrive
- Tell us if parking is tricky
- Mention any tricky access
- Tell us about any previous sealing or DIY attempts

Windows and doors in Pixham
With historic houses such as Polesden Lacey (about 2.6 miles north-west) nearby, there’s older building stock in the area around Pixham as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. 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.
Rented homes near Dorking station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out. For an older house near a landmark such as Pixham Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
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, then guaranteed for a year.
