Questions from Thruxton
Can you help a landlord with a rental near Grateley station?
Yes, we work for landlords and letting agents. You can phone 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before work begins.
Do you cover Thruxton for sand mastic?
Yes. We work across London and the South East, and Thruxton is part of that. You can phone 0345 464 0079 or send us an email and tell us what needs doing.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Do you do commercial work?
Yes. Hotels, offices and other businesses use us and we are fully insured.
Where do you work from?
We work from Crawley. Our applicators cover Thruxton, along with the rest of our area.
Is it OK to seal over old sealant?
No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. It all has to come out first.
What do you need from me for a quote?
Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.
Is it messy?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Sand mastic in Thruxton
Sand mastic does not last for ever, leaving gaps round the window. We rake it out and renew it and tidies the surround. If you are dealing with mastic round period door frames that has failed and draughty sash windows at the surround, we can put it right, whatever the surface.
Somewhere as small as Thruxton, older homes often have timber frames set in stone or brickwork. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.
We stand behind the work with a one-year guarantee.

Do you need sand mastic in Thruxton?
Shallow joints are a common cause. Mastic that’s too thin cracks and drops out so we make sure the new mastic is the right thickness.
Any of these means the joints need attention:
- Mastic dropping out of the joint
- Draughts and rain around sash boxes
- Failed mastic on an exposed elevation
- Tired mastic found when preparing windows for paint
For landlords with property near Grateley station, any sash windows need sound mastic to keep draughts and rain out.
Questions to ask before you book
- How the joint is cleaned and prepared
- What happens if they find a problem under the old sealant
- Which sealant they’ll use, and why
- Which colour the sealant will be
DIY versus a professional finish
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
What sand mastic looks like in Thruxton
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For an older house near a landmark such as Church of St Peter and St Paul, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Managing a site like Amport Church of England Primary School? Then its window and door frames need their mastic kept sound, just like a home’s.

Why deal with it now?
Replacing sash windows is a big decision for a period home and on a listed home, consent may be needed. Where the frames are in good order, new mastic seals the surround. In a small place like Thruxton, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Doing several joints on one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. We will give you a clear quote for the lot.

How the job changes by surface
Sash and case windows
A sash window’s box frame sits in the masonry opening. Sand mastic seals the joint round it.
Timber door frames
Period doors in stone or brick openings are often pointed with sand mastic. We renew it the same way as on windows.
What we can’t put right
A few problems are outside what sealant work can do:
- Crumbling stone or brickwork round the window
- Decayed frames that need repair
- Sash cords, weights and draught-proofing of the sashes
Not sure which it is? You can phone 0345 464 0079 or email us and we will tell you honestly before booking.
What we seal
- Timber door frames
- Period & listed homes
- Sash and case windows
- Tenement windows
- Stone surrounds
- Brick reveals
What we do, step by step
We keep the work tidy and contained to the joints we’re treating, so you can get on with your day. Expect the work to take anything from a few hours to a full day, depending on how many windows. Somewhere as small as Thruxton, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we look at the surrounds with you and agree what needs doing.
- 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 mastic is finished to sit tidily against the stone or brick.
Getting ready for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Move anything stored near the joints
- For business premises, tell us about site rules or sign-in
