How we handle sand mastic in Burcott
A silicone bead around a sash window can look out of place and does not suit the building. Sand mastic gives a finish that matches the age of the house and we can swap the silicone for it. If you are dealing with silicone on a period window that looks wrong and tired mastic found when preparing windows for paint, we can put it right, whatever the surface.
Somewhere as small as Burcott, older homes often have timber frames set in stone or brickwork. Older buildings like these do not always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
The work is covered for a year after we finish. If anything is not right with it, call 0345 464 0079 or send us an email.

Windows and doors in Burcott
The South East is one of 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 live in an older home near Church of St James, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Schools such as Bierton Church of England Combined School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. Letting a property close to Aylesbury station? Then cracked sand mastic around sash windows lets in the draughts tenants complain about.

What happens if it’s left?
If you’re redecorating, renew the mastic first. Painting over failed mastic does not seal it, and the new mastic is traditionally left unpainted. In a small place like Burcott, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

Can you do sand mastic in Burcott?

Can I choose the sealant colour?
Most of the time, yes. We will tell you which colours the right product comes in.
Do I need permission for sand mastic on a listed building?
Speak to your local planning authority before work starts. Sand mastic is often favoured as like for like, but they decide.
Will you leave a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
What do you need from me for a quote?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Are you fully insured?
Yes, we are fully insured for domestic and commercial work.
Do you guarantee sand mastic work?
You get our one-year guarantee on every job.
Can I do it myself?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Landlord and commercial work in Burcott
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
Hotels need rooms back in use, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
Keeping the joints in good condition
Good habits help new joints last longer. A few tips:
- Check with your local planning authority if your home is listed
- Avoid heavy scraping on the mastic joint
- Clear gutters so water doesn’t pour onto the windows
- Check the mastic when you check the paintwork
Avoid painting over the new mastic, which is the traditional advice. If you are redecorating, ask us first.
Sound mastic protects the frame. Failed mastic lets water reach the timber, which can lead to rot.
Honest limits
Before booking, it’s worth knowing the limits:
