Stone surrounds
Sand mastic sits naturally against stone. It finishes to look like part of the surround.
About our sand mastic in East Lockinge
Sand mastic doesn’t last for ever and gaps open up round the frame. Renewing it closes the gap and tidies the surround. If you are dealing with silicone on a period window that looks wrong and weathered mastic on the most exposed windows, we can put it right, whatever the surface.
Mastic can only go onto a dry, clean joint, so window work in East Lockinge is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
Every job comes with our one-year guarantee.

East Lockinge questions
Can you do sand mastic in East Lockinge?
Yes. Our work covers London and the South East, and East Lockinge is part of that. You can call 0345 464 0079 or send us an email and let us know what needs doing, and we will give you a clear quote.
Is East Lockinge within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is it possible to paint over sand mastic?
Sand mastic is normally left unpainted, which is what traditional guidance recommends. Talk to us before any painting near it.
Is consent needed for window work on a listed home?
Speak to your local planning authority before work starts. Sand mastic is often favoured as like for like but the decision is theirs.
Do you remove the old sealant?
Yes, always, and completely. New sealant won’t bond properly to old, so the joint is cleaned back first.
How long does sand mastic take?
As a guide, most jobs take a few hours per window, depending on the condition of the joints. Larger jobs naturally take longer.
Can landlords and businesses book you?
Yes, we do. Domestic, commercial and hotel work are all part of what we do.
What do you need from me for a quote?
A short description and the location. We’ll ask anything else we need to know.

What happens if it’s left?
If you are 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 Lockinge, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, plus any working-time requirements on site. Call for a quick quote and we’ll go through it with you.

How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Ask the planning authority about consent for listed or conservation-area homes
- Make sure water runs off the sill
- Avoid patching sand mastic with silicone
- Plan mastic work ahead of painting
When preparing windows for paint, take care around the mastic. It can be damaged by heavy scraping.
Sound mastic protects the frame. Failed mastic lets water reach the timber and timber that stays wet can rot.
DIY versus a professional finish
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
What affects the quote in East Lockinge
Your quote is based on your job. We take into account:
- Whether old sealant or filler has to be cut out
- How many rooms, windows or areas are involved
- Any working-time requirements on site
- The product the joint needs
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
Helping us quote
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- Where the job is, and your postcode
- If someone has resealed it before
- Access, such as stairs, a lift or height
- Roughly how big the job is
For a quote, call 0345 464 0079 or send us an email with the location and a short description of the problem. You will have a clear quote before work begins.
Windows and doors in East Lockinge
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
In and around East Lockinge, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint. If you live in an older home near Church of All Saints, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

- First, we look at the surrounds with you and agree what needs doing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic is not too thick.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Getting ready for the visit
- Keep pets and children clear of the area while we work
- Where the joints are inside, avoid wetting them before we arrive
- Mention any tricky access
