Sand mastic in Frithend, done properly
Burnt sand mastic is a traditional material that sits naturally against stone and brick. It’s a good fit for period properties, where modern sealant can look out of place. We work on stone surrounds, sash and case windows and period & listed homes, and the jobs we see most are tired mastic found when preparing windows for paint and crumbling sand mastic round a window.
Homes in small places like Frithend 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.
Each job carries a 12-month guarantee.

Frithend questions
Do you work for landlords with property near Bentley (Hampshire) station?
Yes. We work for landlords and letting agents as well as householders. You can call 0345 464 0079 or drop us an email with the details for a clear quote.
Can you do sand mastic in Frithend?
Yes. We work across London and the South East, and Frithend is part of that. Just phone 0345 464 0079 or email us with a few details of the job.
Should I check with the council before work on a listed or conservation-area home?
Speak to your local planning authority before work starts. Sand mastic is often favoured as like for like, but they decide.
Is there any odour?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
Can sand mastic be painted?
Traditional guidance is not to paint over sand mastic. Ask us before you decorate around it and we will talk you through it.
Is it OK to seal over old sealant?
No. Fresh sealant doesn’t stick to old sealant, and it traps any mould or water underneath. It all has to come out first.
Do you do commercial work?
Yes. Hotels, offices and other businesses use us and we’re fully insured.
How do I get a quote for sand mastic in Frithend?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote and we’ll talk you through it.
What affects the cost of sand mastic
Jobs vary more than people expect. What affects the quote:
- Any mould that needs treating
- Whether the work is at height
- When we can work, for business premises
- Which sealant suits the joint
Combining jobs into one visit is generally more efficient than separate visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.
What we need to know
There’s no need for technical detail. It helps if you can tell us:
- If it’s domestic, commercial or a hotel
- Pictures of the joints, sent by email
- Where the job is, and your postcode
- The rough size of the job
It all starts with a short chat. Describe the problem, the location and the size of the job, and we’ll explain how we’d tackle it. Whenever you are ready, ring 0345 464 0079 or drop us an email.
Common problems we fix in Frithend
Scraping and sanding before painting can loosen old mastic. Many people find it crumbling when they prepare the windows, which is a good time to renew it.
The problems people generally mention when they call are:
- Weathered mastic on the most exposed windows
- Window mastic to renew ahead of painting
- Gaps round a timber door in stone or brick
- Patchy fillers round a sash window
Homes close to The Church Of The Good Shepherd include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.
What your quote should include
- Who does the work, and how experienced they are
- How the joint is cleaned and prepared
- How the colour is chosen
- How long to leave it before use
Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

Sand mastic in Frithend: 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. With historic houses such as Farnham Castle (about 4.8 miles north-east) nearby, there’s older building stock in the area around Frithend as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
Rented homes near Bentley (Hampshire) station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out.
Frithend is about 4 miles south-west of Farnham, in Hampshire. Across the GU35 area, we can carry out sand mastic at your property. 683 places in Hampshire are on our list. Reading is on our list too, around 21 miles away.

What’s near Frithend
Typical jobs here are in homes near The Halfway House, among other places. Frithend’s nearest station is Bentley (Hampshire) station, roughly 1.9 miles north-west. Nearby you’ll also find Barley Pound (4 miles north) and Chase Community Hospital (3.5 miles south). For a walk, there’s Deadwater Valley.
Why deal with it now?
New sash windows are a major, costly change and on a listed home, consent may be needed. Where the frames are in good order, new mastic seals the surround. Where a wall is exposed, as many are in small places like Frithend, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Rather than a set price list, 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.
Why us?
- One-year guarantee on every job
- Approved under the ARBOMaster scheme

How the visit works
Good joint work is mostly preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. In total, it generally takes a few hours for a single window, longer for several. Somewhere like Frithend needs a little journey planning: 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.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic is not too thick.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- We dress the surface so it sits neatly against the masonry.
How to prepare
- Mention any leaks or damp you’ve noticed
- Clear items away from the joints we’re working on
- Let us know about parking restrictions
