Sand mastic in Drayton Beauchamp, done properly
Sand mastic skins over fairly quickly but full hardening takes longer. Traditional guidance is not to paint over it, so ask us before you decorate. We are often asked to deal with silicone on a period window that looks wrong and gaps round a timber door in stone or brick, on tenement windows, timber door frames and stone surrounds.
Homes in small places like Drayton Beauchamp 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.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Related advice
Frames and glazing around Drayton Beauchamp
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. Historic houses like Cholesbury Manor House (about 3.6 miles south-east) are a reminder that the area around Drayton Beauchamp has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
Schools such as Goldfield Infants' and Nursery School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. For an older house near a landmark such as Church of St Mary the Virgin, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. For landlords with property near Tring station, cracked sand mastic around sash windows lets in the draughts tenants complain about.

How we quote for sand mastic
Your quote is based on your job. We take into account:
- The old material and how stubborn it is
- How many areas need sealing
- The size of the job
- Access and height
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
Asking for a quote
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- What the problem is, such as mould, gaps, leaks or cracking
- Pictures of the joints, sent by email
- If someone has resealed it before
- Where the job is, and your postcode
Asking for a quote is easy: tell us what needs doing and where, and roughly how big it is. Photos by email help us understand the job, and we will take it from there.
DIY sealant or a professional job?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
If you’re set on DIY, put the effort into 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.
What we cannot put right
In fairness, there are a few things sealant will not fix:
- Sash cords, weights and draught-proofing of the sashes
- Masonry that needs repairing
- Broken panes
If you’re not sure, just phone 0345 464 0079 or send us an email and we’ll give you a straight answer before you book.
