Common problems we fix in Frilford Heath
Age is the main cause. Even well-laid mastic needs renewing in time and how long it lasts depends on the weather it faces.
Keep an eye out for any of the following:
- Patchy fillers round a sash window
- Open joints round the window box
- A silicone bead on a sash window that spoils the look
- Weathered mastic on the most exposed windows
Managing a site like Abingdon Preparatory School? Then the mastic around its windows and doors needs looking after like any other building’s.
Before booking anyone
- Whether VAT is included
- What product goes in the joint
- How the surfaces are prepared before sealing
- Who turns up on the day
Looking after it afterwards
Aftercare is simple:
- Check the mastic when you check the paintwork
- Do not run silicone over sand mastic
- Don’t paint over the new mastic
- Avoid heavy scraping on the mastic joint
Check the mastic when you check the paintwork. Catching cracks early keeps repairs small.
Once mastic starts to crumble, rain gets in. That water can reach the timber frame and the wall so early renewal protects both.

Frilford Heath homes and the weather
Historic houses like Appleton Manor (about 2 miles north) are a reminder that the area around Frilford Heath has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Letting a property close to Radley station? Then any sash windows need sound mastic to keep draughts and rain out. If you live in an older home near Church of St Lawrence, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

What affects the cost of sand mastic
We quote each job individually. These are the things that affect it:
- The size of the job
- When we can work, for business premises
- The type of sealant required
- How easy the joints are to reach
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are not sure whether it needs doing, call 0345 464 0079 or email us and we will give you an honest view and a quote.
What to tell us for a quote
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- Whether it’s a home or a business
- What the problem is, such as mould, gaps, leaks or cracking
- Whether it has been sealed before
- 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 email photos if that is easy.
What happens if it’s left?
New sash windows are a major, costly change, and in listed buildings it may need consent. Where the frames are in good order, new mastic seals the surround. Older cottages and farmhouses around Frilford Heath can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
