How we handle sand mastic in Broughton Crossing
Fresh sand mastic forms a skin quite soon but full hardening takes longer. Traditionally, sand mastic is left unpainted and we’ll advise if you are redecorating. If you have cracked mastic round a front door frame and draughty sash windows at the surround, we can put it right, whatever the surface.
Around Broughton Crossing, 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.
All of our work is guaranteed for twelve months, in Broughton Crossing and everywhere else we cover.

DIY versus a professional finish
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

Is Broughton Crossing within the area you cover?

Do I need permission for sand mastic on a listed building?
Your local planning authority is the one to ask. They’ll tell you if consent is needed for work to your windows.

We help you choose a colour that suits. The choice depends on the product the joint needs.
Are you an approved applicator?

How it works
Once we’re on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for a single window, longer for several. In a small place like Broughton Crossing, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by checking each surround and agreeing the joints to renew.
- We rake out the old mastic and clean the joint.
- We pack any deep gaps so the mastic sits at the right depth.
- 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
- Move anything stored near the joints
- Mention any leaks or damp you’ve noticed

Signs you need sand mastic in Broughton Crossing
Timber swells and shrinks with the weather. The movement cracks the mastic little by little.
If you can see any of these, it’s time to have the joints looked at:
- Old cement repairs round a window that have failed
- Weathered mastic on the most exposed windows
- Crumbling sand mastic round a window
- A silicone bead on a sash window that spoils the look
Schools such as Bierton Church of England Combined School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.
Questions to ask before you book
- What happens if the job turns out different
- What insurance they hold
- What the quote includes, VAT included or not
- What preparation is included
Sand mastic in Broughton Crossing: local notes
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For an older house near a landmark such as Church of St James, the joint between an old wall and a newer frame is generally the first place rain gets in. For landlords with property near Aylesbury station, any sash windows need sound mastic to keep draughts and rain out.

Looking after it afterwards
To keep the joints looking good and working properly:
- Ask a joiner to look at soft timber first
- Ask us before painting near the mastic
- Keep modern sealant off the mastic
- Check the mastic when you check the paintwork
Do not touch or press the mastic while it hardens. It skins over quickly, but takes longer to harden fully.
Good mastic helps keep the frame dry. Once it fails, water can sit against the timber, which can lead to rot.
