- Old sand mastic that has cracked, crumbled or fallen out
How we handle sand mastic in Old Woking
Our applicators renew the sand mastic around sash and case windows and doors set in stone or brick. Out comes the old, loose mastic, the joint is prepared and new mastic is shaped by hand. Common call-outs are for gaps round a timber door in stone or brick and weathered mastic on the most exposed windows, on timber door frames, sash and case windows and brick reveals.
Homes in small places like Old Woking often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
Big or small, it’s backed by our 12-month guarantee in Old Woking and across Surrey.

Why it’s worth doing now in Old Woking
New mastic over crumbling mastic won’t hold. Raking out and preparing the joint gives it a sound base so the new work lasts. Where a wall is exposed, as many are in small places like Old Woking, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first and give you a clear quote before work begins.

How it works
On the day, we look over the joints with you first, so you know exactly what we’re doing. Surfaces next to the work are protected before any work begins. Most jobs take a few hours per window, depending on the condition of the joints. Somewhere as small as Old Woking, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by checking each surround and agreeing the joints to renew.
- Old, loose mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic isn’t too thick.
- 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
- Let us know if you’ve seen damp or leaks
- Plan for the work area to be out of bounds to pets and children
- Where the joints are inside, avoid wetting them before we arrive

When to call us in Old Woking
Rain on the window surround works into any crack and pushes it out. Windows facing the weather tend to go first.
These are the problems we’re asked about most:
- Window mastic to renew ahead of painting
- A silicone bead on a sash window that spoils the look
- Open joints round the window box
- Cement or filler used on old window joints that has cracked
Managing a site like Kingfield Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages.

DIY versus a professional finish
A DIY attempt does not rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
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.

Old Woking homes and the weather
London and the South East are among the drier parts 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 Byfleet Manor (about 3.8 miles north-east) nearby, there’s older building stock in the area around Old Woking as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Letting a property close to Woking station? Then older sash windows in a rental need their mastic kept sound to keep the weather out. If you live in an older home near St Peter's Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
