Do I have to be there?
Access is agreed with you when the job is booked. Indoors, that usually means someone at home.
When will the new mastic be hard?
Not right away. It skins first and hardens fully later and we’ll give you an idea for your job.
What information do you need?
Only a few details: where it is, what you’ve noticed and how we reach it. Then ring 0345 464 0079 or send us an email.
Should I check with the council before work on a listed or conservation-area home?
Speak to your local planning authority before work starts. Like-for-like sand mastic is often the preferred finish but the decision is theirs.

Products from Arbo and Everbuild, among others, picked for each joint. We will tell you what we’re using and why.
About our sand mastic in Glebe Farm
We renew sand mastic around sash windows and doors set in stone or brick. Out comes the old, loose mastic, the joint is prepared and new mastic is shaped by hand. We work on brick reveals, stone surrounds and sash and case windows, and the jobs we see most are window mastic to renew ahead of painting and draughts and rain around sash boxes.
Homes around Glebe Farm range from older properties to newer houses, and their windows range just as widely. The right sealant depends on the frame and on what it sits in.
All of our work is guaranteed for twelve months, in Glebe Farm and everywhere else we cover.

When something else is needed
We’ll always be straight with you, so here’s what new sealant won’t do:
- Rotten sashes, sills or window boxes (a joiner’s job)
- Broken panes
- Planning or listed building consent (your local planning authority decides)
If in doubt, call 0345 464 0079 or drop us an email and we will say what we think.

Why deal with it now?
New sash windows are a major, costly change and on a listed home, consent may be needed. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. Homes in smaller places like Glebe Farm can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.

The process
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take anything from a few hours to a full day, depending on how many windows. A visit to Glebe Farm is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- First we agree which joints need doing.
- We remove the old, loose mastic.
- We pack any deep voids first.
- We apply the mastic by hand and shape it.
- We dress the finish so it sits neatly against the masonry.
Preparing for the visit
- Move anything stored near the joints
- On commercial sites, let us know about site rules
- Try not to wet indoor joints just before the visit

Advice
Common problems we fix in Glebe Farm

- Tired mastic found when preparing windows for paint

What sand mastic looks like in Glebe Farm
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Bletchley Park (about 3.9 miles south-west) nearby, there’s older building stock in the area around Glebe Farm as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
Schools such as St Mary's Wavendon CofE Primary are buildings too, and its window and door frames need their mastic kept sound, just like a home’s. If you live in an older home near Church of St Mary, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

What affects the cost of sand mastic
Jobs vary more than people expect. The main factors:
- Which sealant suits the joint
- How many areas need sealing
- How much old sealant there is and how hard it is to remove
- Mould in or behind the old joints
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
Helping us quote
To help us quote quickly, please include:
- The rough size of the job

How the job changes by surface
Stone surrounds
Stone openings are rarely perfectly straight, so the gap is not the same all the way round. Sand mastic is shaped by hand to suit.
Tenement and terrace windows
Windows above ground floor need the right access. Tell us the height and we’ll confirm what’s needed.
