Windows and doors in North Charford
Historic houses like Breamore House (about 2.8 miles west) are a reminder that the area around North Charford 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. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you look after a building such as Hale Primary School, larger buildings have plenty of frames, and the mastic around each one ages. If you live in an older home near Church of St Mary, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

About our sand mastic in North Charford
Across North Charford, we renew sand mastic around sash and case windows. Every joint is cleaned out and filled by hand for a neat, traditional finish. We are often asked to deal with tired mastic found when preparing windows for paint and cement or filler used on old window joints that has cracked, on timber door frames, tenement windows and sash and case windows.
Around North Charford, 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.
Your job is guaranteed for a year, as with all our work.

How the visit works
When we arrive, we look over the joints with you first, so you know exactly what we’re doing. Surfaces next to the work are protected before any work begins. Most jobs take anything from a few hours to a full day, depending on how many windows. Somewhere like North Charford needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We check the window surrounds and agree which joints need renewing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- The mastic is mixed, pressed into the joint by hand and shaped.
- We dress the surface so it sits neatly against the masonry.
How to prepare
- Mention any parking rules near the property
- Let us know about earlier repairs to the joints
- On commercial sites, let us know about site rules

When something else is needed
To be straight with you, there are a few things sealant won’t fix:
- Whether work needs listed building consent
- Cracked or broken glass
- Rotten sashes, sills or window boxes (a joiner’s job)
Not sure which it is? You can phone 0345 464 0079 or email us and we’ll tell you honestly before booking.
Joints and surfaces we work on
- Stone surrounds
- Brick reveals
- Tenement windows
- Sash and case windows
- Period & listed homes
- Timber door frames
What happens if it’s left?
Silicone might seem the quicker option, but it can look wrong on a period surround. Sand mastic is the traditional material and finishes neatly against the masonry. In a small place like North Charford, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Doing several joints on one visit usually makes better use of the time than several visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.

How we quote for sand mastic
The price is agreed before any work begins. It’s based on:
- Any mould that needs treating
- How many rooms, windows or areas are involved
- Whether old sealant or filler has to be cut out
- Working hours on commercial sites
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.
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:
- How we’d reach the joints
- A few pictures by email, if you can
- If someone has resealed it before
- Where the property is
To get a quote, phone 0345 464 0079 or drop us an email and tell us where the job is and what the problem looks like. We will give you a clear quote before any work starts.
DIY versus a professional finish
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
For landlords and businesses
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. Several properties can be quoted together.
We also work for property managers and facilities teams in North Charford and across Hampshire. We can quote a run of properties together, and we are fully insured for the work.

Aftercare tips
So the new joints stay in good condition:
- Ask the planning authority about consent for listed or conservation-area homes
- Get any rot dealt with first
- Look over the window mastic once a year
- Sort the mastic before the decorators arrive
When preparing windows for paint, take care around the mastic. It can be damaged by heavy scraping.
An open joint round the box lets weather through. Left, the gap tends to get bigger as more mastic falls out.
