Sand mastic in Lunsford
Our applicators renew the sand mastic around sash and case windows and doors set in stone or brick. The old mastic is raked out, the joint is prepared and new mastic is shaped by hand. We work on timber door frames, period & listed homes and tenement windows, and people most often call us about mastic that needs renewing before redecorating and draughts and rain around sash boxes.
Many houses in smaller places like Lunsford have conservatories, garden rooms or patio doors. Those joints need the same attention as the main windows.
There’s a 12-month guarantee on every job, large or small.

What sealant work can’t fix
New sealant cannot fix everything, and we will tell you before any work starts. It won’t solve:
- Sashes that rattle, stick or won’t open
- Damaged stone surrounds
- Planning or listed building consent (your local planning authority decides)
If in doubt, call 0345 464 0079 or drop us an email and we will say what we think.

What the job involves on each surface
Timber door frames
Round a period front door, sand mastic gives the right look.
Tenement and terrace windows
In shared buildings, the windows may be part of a wider repair so it’s worth checking responsibilities.
What affects the cost of sand mastic
The quote reflects the job in front of us. We take into account:
- Which sealant suits the joint
- How many rooms, windows or areas are involved
- Any mould that needs treating
- The amount of work
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we will go through it with you.
Helping us quote
You do not need to know the technical terms. It helps if you can tell us:
- Where the job is, and your postcode
- If someone has resealed it before
- How we’d reach the joints
- How many joints, rooms or windows are involved
There’s no standard price list, because every job is different. Instead, your job gets its own clear quote. To arrange one, call 0345 464 0079 or email us.
Landlords, agents and businesses in Lunsford
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
For anyone letting property in or around Lunsford, several properties can be quoted together. Just tell us the addresses and what each one needs.
Why it’s worth doing now in Lunsford
Cement-based fillers and modern sealants don’t always suit a period surround. Sand mastic is the like-for-like choice and that can be important for listed homes. In an older home around Lunsford, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
The cost reflects the work involved, not guesswork. That is why we ask a few questions first and agree the price before starting.

How it works
On the day, we start by going over the job with you, so you know exactly what we’re doing. Surfaces next to the work are protected before any work begins. The work normally takes anything from a few hours to a full day, depending on how many windows. For a job in Lunsford, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- First, we look at the surrounds with you and agree what needs doing.
- We rake out the old mastic and clean the joint.
- Deep voids are packed so the mastic is the right thickness.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Before we arrive
- Mention any tricky access
- On commercial sites, let us know about site rules
- Mention any leaks or damp you’ve noticed

Frames and glazing around Lunsford
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. With historic houses such as Starkey Castle (about 3.8 miles north) nearby, there’s older building stock in the area around Lunsford as well as newer homes.

In the older streets around Church of the Holy Trinity, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
