Sand mastic for sash & case windows in Fifield, Oxfordshire
Sand mastic across Fifield and nearby, with every bit of old sealant taken out first and a one-year guarantee.
- Draughts and rain around sash boxes
- Cement or filler used on old window joints that has cracked
- Failed mastic on an exposed elevation
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 small place like Fifield, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
What you pay reflects the work, not guesswork. That is why we ask a few questions first and send you a clear quote before we start.
What you get with us
- A 12-month guarantee on all work
- 180+ five-star Google reviews
- Domestic, commercial and hotel work
- Full insurance on every job
How we handle sand mastic in Fifield
Sand mastic suits most period window surrounds. 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 tenement windows, and people most often call us about mastic worn away on windows facing the weather and mastic that needs renewing before redecorating.
Around Fifield, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

What affects the quote in Fifield
Call for a quick quote. The main things that affect it are:
- The product the joint needs
- How many areas need sealing
- Any mould that needs treating
- Whether old sealant or filler has to be cut out
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
Helping us quote
You do not need to know the technical terms. It helps if you can tell us:
- Any previous sealing or DIY work
- The address or postcode of the job
- How many joints, rooms or windows are involved
- What the problem is, such as mould, gaps, leaks or cracking
For a quote, phone 0345 464 0079 or send us an email and tell us where the job is and what the problem looks like. You’ll have a clear quote before work begins.
DIY sealant or a professional job?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
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 doesn’t work out, we can still put it right.
What we can’t put right
To be straight with you, there are a few things sealant will not fix:
- Whether work needs listed building consent
- Cracked or broken glass
- Masonry that needs repairing
If in doubt, phone 0345 464 0079 or drop us an email and we’ll say what we think.
What we seal
- Period & listed homes
- Stone surrounds
- Brick reveals
- Sash and case windows
- Timber door frames
- Tenement windows
What we do, step by step
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes a few hours for a single window, longer for several. For a village or hamlet like Fifield, 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.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic isn’t 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.
Before we arrive
- Where the joints are inside, avoid wetting them before we arrive
- Mention if the joints have been sealed before
- Let us know about stairs, lifts or work at height

Your questions about sand mastic in Fifield
Is Fifield within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you help a landlord with a rental near Shipton station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before work begins.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you do not need to watch us work.
Is it possible to take out silicone and use sand mastic instead?
In most cases. The silicone is cut out and the joint cleaned before the sand mastic goes in.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we will tell you what we are using.
Are you ARBOMaster approved?
Yes. We hold ARBOMaster approved applicator status, and we’re fully insured.
Are you insured?
Yes. We’re fully insured.
Is it worth trying it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.

When to call us in Fifield
Sand mastic slowly weathers. It dries out, cracks and loses its grip from the frame or the masonry.
Any of these means the joints need attention:
- Draughty sash windows at the surround
- Window mastic to renew ahead of painting
- Old cement repairs round a window that have failed
- Mastic round period door frames that has failed
Homes close to Church of St John the Baptist include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.
