How we quote for sand mastic
Every job gets its own quote. This is what makes a difference:
- The number and length of the joints
- How many areas need sealing
- The product the joint needs
- How easy the joints are to reach
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
Asking for a quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- Whether it has been sealed before
- Roughly how big the job is
- What’s wrong with the joints now
- The address or postcode of the job
Getting a quote is simple: let us know what needs doing and where, and roughly how big it is. A few photos by email make the job easier to understand, and we’ll take it from there.
About our sand mastic in Shefford Woodlands
We renew sand mastic around sash windows and doors in stone and brick. Out comes the old, loose mastic, the joint is prepared and new mastic is shaped by hand. We’re often asked to deal with silicone on a period window that looks wrong and draughty sash windows at the surround, across tenement windows, sash and case windows and brick reveals.
Mastic can only go onto a dry, clean joint, so window work in Shefford Woodlands is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
Big or small, you get the same one-year guarantee in Shefford Woodlands and across West Berkshire.

Sand mastic in Shefford Woodlands: 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 Stephen, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Keep an eye out for any of the following:
- Cement or filler used on old window joints that has cracked
- Weathered mastic on the most exposed windows
- Modern sealant on a period surround
- Tired mastic found when preparing windows for paint

If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each surround is checked first.

- Large voids are packed out.
- New sand mastic is applied and shaped by hand.

Leave it or put it right?
Cement-based fillers and modern sealants do not always suit a period surround. Sand mastic is the like-for-like choice and that can be important for listed homes. Older cottages and farmhouses around Shefford Woodlands can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Combining jobs into one visit is usually more efficient than separate visits, so it’s worth mentioning everything you’d like done. We will give you a clear price for the lot.

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Don’t paint over the new mastic
- Keep modern sealant off the mastic
- Find out about consent before window work on a listed home
- Look over the window mastic once a year
Leave the new mastic unpainted, which is the traditional advice. Ask us before any decorating around it.
Gaps round a sash box let in draughts and rain. The longer it’s left, the more the joint opens.
