Your questions about sand mastic in East Shefford
Is East Shefford within the area you cover?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Can you help a landlord with a rental near Kintbury station?
Yes. We work for letting agents and landlords as well as householders. You can phone 0345 464 0079 or email us with the details for a clear quote.
Should I try DIY first?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.
How long does sand mastic take?
Most jobs take anything from a few hours to a full day, depending on how many windows, including preparation and clearing up. We will confirm how long when we quote.
Does someone need to be in?
We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.
Do you offer different sealant colours?
In most cases you can choose. We will tell you which colours the right product comes in.
Are you an approved applicator?
Yes. We are an ARBOMaster approved applicator.
What does sand mastic cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote and we’ll talk you through it.
Sand mastic for homes and businesses in East Shefford
Traditional burnt sand mastic blends with stone and brick surrounds. It’s a good fit for period properties where a modern sealant bead would stand out. If you have mastic round period door frames that has failed and a silicone bead on a sash window that spoils the look, we can help, whatever the surface.
Around East Shefford, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.

When to call us in East Shefford
Scraping and sanding before painting can loosen old mastic. It’s often found when windows are being prepared for paint, which is a good time to renew it.
The problems people usually mention when they call include:
- Weathered mastic on the most exposed windows
- Patchy fillers round a sash window
- Crumbling sand mastic round a window
- Mastic that needs renewing before redecorating
Managing a site like Shefford C.E. Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages.

Windows and doors in East Shefford
London and the South East are among 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 Kintbury station, any sash windows need sound mastic to keep draughts and rain out. In the older streets around St Thomas' Church, the joint between an old wall and a newer frame is generally the first place rain gets in.

What happens if it’s left?
If you’re redecorating, renew the mastic first. Painting over failed mastic does not seal it and traditional guidance is to leave the new mastic unpainted. Where a wall is exposed, as many are in small places like East Shefford, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are not sure whether it needs doing, ring 0345 464 0079 or email us for an honest opinion and a quote.

Can I do it myself?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
