Ecchinswell Sand Mastic
Problem with your window and door surrounds in Ecchinswell? We remove the old material, prepare the joints and seal them properly.
- Mastic worn away on windows facing the weather

- Tired mastic found when preparing windows for paint
Sand mastic in Ecchinswell, done properly
Fresh sand mastic forms a skin quite soon but full hardening takes longer. Traditionally, sand mastic is left unpainted and we’ll advise if you are redecorating. If you are dealing with silicone on a period window that looks wrong and crumbling sand mastic round a window, we can help.
Around Ecchinswell, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
The work is covered for a year after we finish. If anything isn’t right with it, ring 0345 464 0079 or send us an email.

How long does the job take?

Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Is the work guaranteed?

What do you put in the joint?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.

We also work for property managers and facilities teams. We can quote a run of properties together, and we are fully insured for the work.
We work for landlords and letting agents as well as homeowners. Sealant work between tenants keeps a property looking cared for.

What else we do in Ecchinswell
What we’re called out for in Ecchinswell
Most of it is simply age. Sand mastic is a maintenance item like any pointing, depending on exposure and upkeep.
Most people get in touch after spotting one of these:
- Draughts and rain around sash boxes
- Cracked mastic round a front door frame
- Silicone on a period window that looks wrong
- Crumbling sand mastic round a window
Rented homes near Thatcham station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out.

DIY sealant or a professional job?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
How it works
There is not much for you to do on the day. Show us the job and we’ll take it from there. The job generally takes anything from a few hours to a full day, depending on how many windows. In a small place like Ecchinswell, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check each window surround and the condition of the joint.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic isn’t too thick.
- New sand mastic is applied and shaped by hand.
- The finish is dressed neatly.
How to prepare
- For indoor joints, keep the area dry beforehand if you can
- Mention any parking rules near the property
- Let us know if you’ve seen damp or leaks

What sand mastic looks like in Ecchinswell
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. Historic houses like Highclere Castle (about 3.4 miles west) are a reminder that the area around Ecchinswell 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.
In the older streets around Church of St Lawrence, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. If you look after a building such as Ecchinswell and Sydmonton Church of England Primary School, the mastic around its windows and doors needs looking after like any other building’s.
Ecchinswell is about 5 miles south of Newbury, in West Berkshire.

What the job involves on each surface
Timber door frames
Door frames get knocked and soaked, so their mastic can fail sooner. It’s renewed by hand.
Brick reveals
Loose mastic comes out and deep gaps are packed before pointing.
Why act early in Ecchinswell
Not every draught comes from the sashes themselves. Gaps between the frame and the wall can be just as bad, and renewing the mastic closes them. Around Ecchinswell, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
We do not show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we’ll talk you through it.
