What sand mastic looks like in West Horsley
Historic houses like Hatchlands Park (about 1.6 miles south-west) are a reminder that the area around West Horsley has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. 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.
For landlords with property near Horsley station, cracked sand mastic around sash windows lets in the draughts tenants complain about. In the older streets around Church of St Mary the Virgin, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Sand mastic for homes and businesses in West Horsley
On many period windows, sand mastic looks right and suits the building. On modern frames we’d normally use a flexible sealant and we will explain which is best for yours. We work on stone surrounds, brick reveals and timber door frames, and people most often call us about draughty sash windows at the surround and open joints round the window box.
Many houses in smaller places like West Horsley have conservatories, garden rooms or patio doors. Those joints need the same attention as the main windows, and any older timber or sash windows need a sealant that suits them.
Whatever the size of the job, it’s backed by our one-year guarantee.

Combining jobs into one visit generally makes better use of the time than several visits, so tell us about everything that needs sealing. We will send you a clear quote for the lot.

To make quoting easier, let us know:
- Access, such as stairs, a lift or height

A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and add pictures by email if you can.

The process
The work is kept neat and contained to the joints we’re treating, 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.

- Each surround is checked first.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic isn’t too thick.
- New sand mastic is applied and shaped by hand.
- The finish is dressed neatly.

Advice
Signs you need sand mastic in West Horsley
Decorating can disturb tired mastic. It’s often found when windows are being prepared for paint.
Common reasons people contact us include:
- Old sand mastic that has cracked, crumbled or fallen out
- Failed mastic on an exposed elevation
- A silicone bead on a sash window that spoils the look
- Window mastic to renew ahead of painting
If you look after a building such as The Raleigh School, larger buildings have plenty of frames, and the mastic around each one ages.
Before you book anyone
- What happens if they find a problem under the old sealant
- Which sealant they’ll use, and why
- What insurance they hold
- Who does the work, and how experienced they are
How to look after the new joints
So the new joints stay in good condition:
- Clear gutters so water doesn’t pour onto the windows
- Renew mastic before redecorating the windows
- Avoid heavy scraping on the mastic joint
- Do not run silicone over sand mastic
Leave the new mastic alone while it firms up. It forms a skin fairly soon, but takes longer to harden fully.
It’s best to renew mastic before painting the windows. Painting over failed mastic hides the problem for a while.

How do I get a quote for sand mastic in West Horsley?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Which products do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice.
Can I choose the sealant colour?
In most cases you can choose. We will tell you which colours the right product comes in.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Can I paint the new mastic?
The usual advice is to leave sand mastic unpainted. If you’re redecorating the window, ask us first and we’ll talk you through it.
Is it OK to seal over old sealant?
No. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.

Should I try it myself first?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What happens if it’s left?
Not every filler suits an old window surround. Sand mastic matches what was there and that can be important for listed homes. In a smaller place like West Horsley, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
