Surface by surface
Stone surrounds
Stone openings are rarely perfectly straight, so the gap isn’t the same all the way round. Sand mastic is shaped by hand to suit.
Timber door frames
Round a period front door, sand mastic gives the right look.
Sand mastic in Burham
We renew sand mastic around sash windows and doors in stone and brick. The old mastic is raked out, and new mastic is applied and shaped by hand. We work on stone surrounds, sash and case windows and tenement windows, and the jobs we see most are cracked mastic round a front door frame and draughts and rain around sash boxes.
Mastic can only go onto a dry, clean joint, so window work in Burham is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
The work is covered for a year after we finish. If anything is not right with it, call 0345 464 0079 or send us an email.

The process
At the end, we look at the finished work together and tell you how long to leave it. The work normally takes a few hours for a single window, longer for several, depending on the size of the job. Somewhere as small as Burham, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, we look at the surrounds with you and agree what needs doing.
- Old, loose 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.
Getting ready for the visit
- Plan for the work area to be out of bounds to pets and children
- Let us know about parking restrictions
- Let us know about earlier repairs to the joints

Leave it or put it right?
Silicone might seem the quicker option, but on period stone or brick it often looks out of place. Sand mastic suits the building and blends with the stone or brick. In a small place like Burham, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
What you pay reflects the work, not guesswork. That is why we ask a few questions first and give you a clear quote before we start.

Burham homes and the weather
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Starkey Castle (about 2.4 miles north) are a reminder that the area around Burham 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.
Managing a site like Burham Church of England Primary School? Then the mastic around its windows and doors needs looking after like any other building’s. Letting a property close to Snodland station? Then any sash windows need sound mastic to keep draughts and rain out.

Which is right for my windows, sand mastic or modern sealant?
For period timber windows in stone or brick, sand mastic is often the better fit. Modern frames normally suit a flexible sealant, and we will explain why.
What do you put in the joint?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference.
How much does sand mastic cost in Burham?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You will get a clear quote before any work starts.
Do I need permission for sand mastic on a listed building?
It’s best to ask your local planning authority first. Like-for-like sand mastic is often the preferred finish, but they decide.
For landlords and businesses
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. We can quote for more than one property at once.
We also work for property managers and facilities teams in Burham and across Medway. Several sites can be quoted together.
DIY sealant or a professional job?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
When to call us in Burham
Water gets into small cracks in the mastic and pushes it out. Windows facing the weather tend to go first.
If you can see any of these, it’s time to have the joints looked at:
- Draughts and rain around sash boxes
- Silicone on a period window that looks wrong
- Window mastic to renew ahead of painting
- Mastic dropping out of the joint
For an older house near a landmark such as St Mary's Church, the joint between an old wall and a newer frame is generally the first place rain gets in.
Questions to ask before booking
- How the surfaces are prepared before sealing
- What product goes in the joint
- Who does the work, and how experienced they are
- When the joint can take water or movement
