Why deal with it now?
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. Where a wall is exposed, as many are in small places like Rodmell, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
The cost depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before work begins, so you know where you stand.

Sand mastic in Rodmell, done properly
Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s a mix of sand and a linseed-oil-based binder, applied by hand. On period homes, it looks right where silicone wouldn’t. We’re often asked to deal with crumbling sand mastic round a window and failed mastic on an exposed elevation, on period & listed homes, tenement windows and timber door frames.
Around Rodmell, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
Your job is guaranteed for a year, as with all our work.

How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Ask the planning authority about consent for listed or conservation-area homes
- Renew mastic before redecorating the windows
- Ask us before painting near the mastic
- Don’t run silicone over sand mastic
Don’t run silicone over the new mastic. If anything cracks, get it looked at rather than patching it.
Fine cracks show the mastic is starting to fail. It’s easier to renew it before it drops out.
Common problems we fix in Rodmell
Most of it is simply age. Sand mastic is a maintenance item like any pointing, depending on exposure and upkeep.
The most common problems we see are:
- Old cement repairs round a window that have failed
- Mastic round period door frames that has failed
- Mastic dropping out of the joint
- Draughty sash windows at the surround
Letting a property close to Southease station? Then older sash windows in a rental need their mastic kept sound to keep the weather out.

Landlord and commercial work in Rodmell
Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.
We work for letting agents and landlords as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order.
What we do, step by step
Good joint work is mostly preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours per window, depending on the condition of the joints. Somewhere as small as Rodmell, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each surround is checked first.
- 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.
- We finish the mastic to a tidy line.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any parking rules near the property

Should I try it myself first?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.
Frames and glazing around Rodmell
Historic houses like Monk's House (about 0.4 miles north-east) are a reminder that the area around Rodmell 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’s 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.
In the older streets around St Peter's Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. For site and facilities teams at buildings such as Priory School, larger buildings have plenty of frames, and the mastic around each one ages.

Common questions in Rodmell
Is Rodmell within the area you cover?
Yes, Rodmell is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.

Do you do commercial work?
Yes. Hotels, offices and other businesses use us, and we’re fully insured.
Does someone need to be in?
We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.
Should I use sand mastic or silicone?
We’ll talk it through with you. Period homes often look best with sand mastic, and modern sealants suit newer frames.
What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We will tell you what we are using and why.
Will the old sealant be removed?
Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
