Sand mastic for homes and businesses in Friar's Hill
Sand mastic skins over fairly quickly but full hardening takes longer. Traditionally, sand mastic is left unpainted, so ask us before you decorate. Typical jobs include failed mastic on an exposed elevation and tired mastic found when preparing windows for paint, across period & listed homes, brick reveals and stone surrounds.
Homes in small places like Friar's Hill often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
There’s a 12-month guarantee on every job, large or small.

What the job involves on each surface
Sash and case windows
Most of our sand mastic work is on sash windows. We renew the mastic round each box.
Brick reveals
Gaps between frame and brick let in rain and draughts. New mastic seals the gap.
For landlords and businesses
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.

What else we do in Friar's Hill
Frames and glazing around Friar's Hill
Friar's Hill is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For site and facilities teams at buildings such as Guestling Bradshaw Church of England Primary School, larger buildings have plenty of frames, and the mastic around each one ages. In the older streets around St Laurence's Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Common questions in Friar's Hill
Can you help a landlord with a rental near Three Oaks station?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before work begins.
Is sand mastic in a coastal place like Friar's Hill any different?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
What does sand mastic cost?
We don’t publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Can I choose the sealant colour?
Most of the time, yes. We’ll tell you which colours the right product comes in and agree one before we start.
Can you seal over the old sealant?
No. The old sealant always comes out first, so the new sealant bonds properly.
Is it possible to paint over sand mastic?
It’s traditionally left unpainted, which is what traditional guidance recommends. Talk to us before any painting near it.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Do you work in Friar's Hill?
We do. Our applicators work in Friar's Hill.
Keeping the joints in good condition
Looking after new joints is easy, and it makes a real difference:
- Keep sills and gutters clear so water drains away
- Look over the window mastic once a year
- Have rotten timber repaired before new mastic goes in
- Sort the mastic before the decorators arrive
Don’t touch or press the mastic while it hardens. It skins over quickly, but takes longer to harden fully.
Crumbling mastic lets rain into the joint. It can soak into the frame and the surrounding masonry so early renewal protects both.
The process
We keep the work tidy and contained to the area we are working on, so you can carry on as normal. Expect the work to take a few hours for a single window, longer for several, and we tell you how long to leave it before we go. For a village or hamlet like Friar's Hill, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First, we look at the surrounds with you and agree what needs doing.
- We rake out the old mastic and clean the joint.
- Large voids are packed out first, so the mastic is not too thick.
- The mastic is mixed, pressed into the joint by hand and shaped.
- We dress the surface so it sits neatly against the masonry.
Before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- Try not to wet indoor joints just before the visit
- Mention any leaks or damp you’ve noticed

Advice
What we are called out for in Friar's Hill
Timber frames move with the seasons. That movement opens up the mastic joint over time.
The problems people usually mention when they call are:
- Weathered mastic on the most exposed windows
- Gaps between timber frames and stone or brick
- Wind and rain getting in round a sash window
- A silicone bead on a sash window that spoils the look
If you let a flat or house near Three Oaks station, older sash windows in a rental need their mastic kept sound to keep the weather out.
Before you book anyone
- What happens if the job turns out different
- Which colour the sealant will be
- Are they insured?
- How long the guarantee is
Why deal with it now?
If you’re redecorating, renew the mastic first. Painting over failed mastic does not seal it and traditional guidance is to leave the new mastic unpainted. Where a wall is exposed, as many are in small places like Friar's Hill, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.
What you get with us
- Approved under the ARBOMaster scheme
- Over 20 years’ experience
- We’re fully insured
- Anti-fungal silicone where joints get wet
