How we handle sand mastic in Upper Bucklebury
On many period windows, sand mastic looks right and suits the building. On modern frames we’d normally use a flexible sealant and we’ll explain which is best for yours. Common call-outs are for mastic worn away on windows facing the weather and window mastic to renew ahead of painting, on brick reveals, timber door frames and stone surrounds.
Outdoor sealant needs dry, clean surfaces, so work on frames around Upper Bucklebury is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
We stand behind the work with a one-year guarantee, so you are not left on your own once the job is done.

Frames and glazing around Upper Bucklebury
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. Historic houses like Shaw House (about 4 miles west) are a reminder that the area around Upper Bucklebury 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.
If you look after a building such as Bucklebury C.E. Primary School, its window and door frames need their mastic kept sound, just like a home’s. If you let a flat or house near Thatcham station, any sash windows need sound mastic to keep draughts and rain out.

Why it’s worth doing now in Upper Bucklebury
Cement-based fillers and modern sealants do not always suit a period surround. Sand mastic is the like-for-like choice and that can be important for listed homes. Around Upper Bucklebury, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Combining jobs into one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. We’ll give you a clear quote for the lot.

Do you need sand mastic in Upper Bucklebury?
Rain on the window surround works into any crack and pushes it out. Windows facing the weather tend to go first.
Common reasons people contact us are:
- A silicone bead on a sash window that spoils the look
- Cement or filler used on old window joints that has cracked
- Mastic that needs renewing before redecorating
- Draughty sash windows at the surround
If you live in an older home near All Saints, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

- Which sealant they’ll use, and why
- Whether you can choose the colour
- What happens if they find a problem under the old sealant
- Is the old sealant removed completely?
Looking after it afterwards
A little care helps the new joints last. We recommend:
- Do not run silicone over sand mastic
- Sort the mastic before the decorators arrive
- Make sure water runs off the sill
- Find out about consent before window work on a listed home
Make sure water drains away from the window surround. Constant wetting wears the mastic faster.
Crumbling mastic lets rain into the joint. It can soak into the frame and the surrounding masonry, so renewing it early is worth it.

How we quote for sand mastic
Jobs vary more than people expect. The main factors:
- Mould in or behind the old joints
- Whether the work is at height
- Which sealant suits the joint
- How many areas need sealing
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.
What we need to know
Photos by email are helpful but not essential. Try to tell us:
- What the problem is, such as mould, gaps, leaks or cracking
- How we’d reach the joints
- Any previous sealing or DIY work
- If it’s domestic, commercial or a hotel
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we’ll explain how we’d tackle it. When it suits you, phone 0345 464 0079 or send us an email.
Can I do it myself?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
