Sand mastic for homes and businesses in Fairford Leys
Sand mastic suits most period window surrounds. On modern frames we’d normally use a flexible sealant, and we’ll talk through which suits your home. Common call-outs are for cement or filler used on old window joints that has cracked and failed mastic on an exposed elevation, on brick reveals, period & listed homes and stone surrounds.
In smaller places like Fairford Leys, homes range from older cottages to newer houses, with windows to match: timber, uPVC and aluminium. The right sealant depends on the frame and on what it sits in.
All of our work is guaranteed for twelve months.

How to look after the new joints
No joint lasts for ever, but care makes a real difference. Our tips:
- Leave the new mastic unpainted
- Sort the mastic before the decorators arrive
- Avoid patching sand mastic with silicone
- Take care around the mastic when scraping paint
Check the mastic when you check the paintwork. Catching cracks early keeps repairs small.
Renewing mastic before redecorating saves doing it twice. Paint over cracked mastic only covers it up.
What the job involves on each surface
Sash and case windows
The mastic round a sash window is on show so we finish it carefully.
Brick reveals
We rake out the old mastic and pack deep voids before pointing.
Fairford Leys homes and the weather
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Waddesdon Manor (about 4.6 miles north-west) nearby, there’s older building stock in the area around Fairford Leys 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.
If you live in an older home near Fairford Leys Church, the joint between an old wall and a newer frame is generally the first place rain gets in. If you let a flat or house near Aylesbury station, any sash windows need sound mastic to keep draughts and rain out.

DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
What we do, step by step
There’s no need to move everything out, just the space around the work. We protect the rest, and the job takes anything from a few hours to a full day, depending on how many windows for a typical job. A visit to Fairford Leys is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We look at the surrounds with you and agree the joints to renew.
- Old mastic and any loose material are raked out.
- Deep gaps are packed so the mastic sits at the right depth.
- We apply the mastic by hand and shape it.
- We dress the finish so it sits neatly against the masonry.
Getting ready for the visit
- Move anything stored near the joints
- On commercial sites, let us know about site rules
- Mention if the joints have been sealed before

Is Fairford Leys within the area you cover?

How long does sand mastic take to go off?

What sealant do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we will explain our choice.
Will it make a mess?
No. The area is protected while we work and cleaned up afterwards.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Is the work guaranteed?
Our 12-month guarantee covers every job.
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.
Common problems we fix in Fairford Leys
Age is the main cause. Sand mastic is a maintenance item like any pointing and how long it lasts depends on the weather it faces.
It’s worth asking for a quote if you see:
- Old cement repairs round a window that have failed
- Open joints round the window box
- Old sand mastic that has cracked, crumbled or fallen out
- Weathered mastic on the most exposed windows
Schools such as St Mary's Church of England School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.
