On a listed home or in a conservation area, the right material matters. Like-for-like sand mastic is generally favoured.
Stone surrounds
Stone surrounds suit sand mastic well. The finish blends with the masonry.
Sand mastic in Ramsden
Sand mastic suits most period window surrounds. On modern frames we’d normally use a flexible sealant and we’ll explain which is best for yours. We work on sash and case windows, period & listed homes and timber door frames, and common reasons people get in touch are mastic that needs renewing before redecorating and old cement repairs round a window that have failed.
In a village or hamlet like Ramsden, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
Whatever the size of the job, you get the same one-year guarantee in Ramsden and across Oxfordshire.

How to look after the new joints
Joint life depends on how it’s used and looked after. We suggest:
- Clear gutters so water does not pour onto the windows
- Keep modern sealant off the mastic
- Renew mastic before redecorating the windows
- Go gently near the mastic when preparing windows
Avoid painting over the new mastic, which is the traditional advice. Ask us before any decorating around it.
An open joint round the box lets weather through. The longer it’s left, the more the joint opens.
Leave it or put it right?
Gaps round a sash window let in rain and draughts. Left, water can reach the timber and the wall, so dealing with it now protects both. Around Ramsden, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.

- Neat joints and a tidy finish
- Approved under the ARBOMaster scheme

What sand mastic looks like in Ramsden
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Minster Lovell Hall (about 3.1 miles south-west) nearby, there’s older building stock in the area around Ramsden as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
If you let a flat or house near Finstock station, any sash windows need sound mastic to keep draughts and rain out. Homes close to Church of St James include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

What we are called out for in Ramsden
Over the years, sand mastic weathers. It hardens, cracks and starts to come away from the frame or the masonry.
If you can see any of these, it’s time to have the joints looked at:
- Silicone on a period window that looks wrong
- Mastic that needs renewing before redecorating
- Weathered mastic on the most exposed windows
- Cement or filler used on old window joints that has cracked
For site and facilities teams at buildings such as Finstock Church of England Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

How it works
On the day, we look over the joints with you first. Surfaces next to the work are protected before any work begins. The work normally takes a few hours per window, depending on the condition of the joints. In a small place like Ramsden, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by checking each surround and agreeing the joints to renew.
- We rake out the old mastic and clean the joint.
- Large voids are packed out first, so the mastic isn’t too thick.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- We dress the surface so it sits neatly against the masonry.
Before we arrive
- Mention any sign-in or site rules at work premises
- Let us know about stairs, lifts or work at height
- Plan for the work area to be out of bounds to pets and children

Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
How we quote for sand mastic
The price is agreed before any work begins. It takes into account:
- How easy the joints are to reach
- Mould in or behind the old joints
- How many rooms, windows or areas are involved
- When we can work, for business premises
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
Asking for a quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- Whether it’s a home or a business
- What’s wrong with the joints now
- The rough size of the job
- Whether it has been sealed before
For a quick quote, get us on the phone, or send an email if you’d rather. Describe what needs sealing and we’ll talk you through the work.
