About our sand mastic in Axmansford
On many period windows, sand mastic looks right and suits the building. Newer frames generally get a flexible sealant instead, and we’ll talk through which suits your home. We work on period & listed homes, brick reveals and tenement windows, and the jobs we see most are draughty sash windows at the surround and old sand mastic that has cracked, crumbled or fallen out.
Mastic can only go onto a dry, clean joint, so window work in Axmansford is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
Big or small, it’s backed by our one-year guarantee in Axmansford and across Hampshire.

What else we do in Axmansford
Sand mastic in Axmansford: local notes
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as The Vyne (about 4.9 miles south-east) nearby, there’s older building stock in the area around Axmansford as well as newer homes. 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.
For landlords with property near Midgham station, older sash windows in a rental need their mastic kept sound to keep the weather out. If you look after a building such as The Hurst School, the mastic around its windows and doors needs looking after like any other building’s. Homes close to Church of St Stephen include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Why deal with it now?
New sash windows are a major, costly change, and in listed buildings it may need consent. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. Where a wall is exposed, as many are in small places like Axmansford, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
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.

How it works
All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. Most jobs take anything from a few hours to a full day, depending on how many windows. In a small place like Axmansford, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- Deep gaps are packed so the mastic sits at the right depth.
- We apply the mastic by hand and shape it.
- The surface is finished to suit the stone or brick.
Before we arrive
- Move anything stored near the joints
- On commercial sites, let us know about site rules
- Mention if the joints have been sealed before

Advice
Aftercare tips
To keep the joints looking good and working properly:
- Keep modern sealant off the mastic
- Check the mastic when you check the paintwork
- Sort the mastic before the decorators arrive
- Ask us before painting near the mastic
Do not run silicone over the new mastic. If anything cracks, get it looked at rather than patching it.
It’s best to renew mastic before painting the windows. Painting over failed mastic hides the problem for a while.

It’s the traditional filler for the joint round timber windows and doors. It combines sand with a linseed-oil-based binder.

For landlords and businesses
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
Failed sealant is one of the commonest items on a check-out report. Several properties can go on one quote.
DIY sealant or a professional job?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
