Sand mastic in Farley Hill
If your home is listed or in a conservation area, check with your local planning authority if consent is needed before window work. Like-for-like sand mastic is often the preferred finish. Common call-outs are for cement or filler used on old window joints that has cracked and silicone on a period window that looks wrong, across stone surrounds, timber door frames and sash and case windows.
Somewhere as small as Farley Hill, older homes often have timber frames set in stone or brickwork. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.
We stand behind the work with a 12-month guarantee, so you are covered after we’ve gone.

What sealant work cannot fix
Sealant isn’t the answer to every problem, and we will tell you before any work starts. Sealant will not put right:
- Sash cords, weights and draught-proofing of the sashes
- Damaged stone surrounds
- Planning or listed building consent (your local planning authority decides)
If you are not sure, just ring 0345 464 0079 or drop us an email and we will give you a straight answer before booking.

How the visit works
A visit follows a simple pattern: we check the joints, protect the area around them, do the work and tidy away. It usually takes a few hours for a single window, longer for several. For a village or hamlet like Farley 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.
- We start by checking each surround and agreeing the joints to renew.
- Old, loose mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- 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 parking rules near the property
- Plan for the work area to be out of bounds to pets and children
- Let us know about stairs, lifts or work at height

Sand mastic in Farley Hill: local notes
Historic houses like Stratfield Saye House (about 3.9 miles south-west) are a reminder that the area around Farley Hill 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.
Homes close to St Eligius include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Rented homes near Wokingham station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out.

Aftercare tips
To keep the joints looking good and working properly:
- Keep modern sealant off the mastic
- Plan mastic work ahead of painting
- Ask the planning authority about consent for listed or conservation-area homes
- Clear gutters so water doesn’t pour onto the windows
Look at the mastic when you look over the windows. Catching cracks early keeps repairs small.
Small cracks are a sign the mastic is ageing. It’s easier to renew it before it drops out.
Should I try it myself first?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

Do you have insurance?

What’s sand mastic made of?
Sand plus a binder based on linseed oil. It’s built up in the joint by hand and shaped to suit the surround.

The usual advice is to leave sand mastic unpainted. If you are redecorating the window, ask us first and we’ll talk you through it.
What we’re called out for in Farley Hill
Over the years, sand mastic weathers. It hardens, cracks and starts to come away on the stone or timber.
Most people get in touch when they notice something like this:
- A silicone bead on a sash window that spoils the look
- Window mastic to renew ahead of painting
- Open joints round the window box
- Draughts and rain around sash boxes
Schools such as Farley Hill Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.
