- Open joints round the window box
- Tired mastic found when preparing windows for paint
- Modern sealant on a period surround
What we do, step by step
Every visit runs the same way: we check the joints, protect the area around them, carry out the job and tidy away. It generally takes anything from a few hours to a full day, depending on how many windows. Somewhere as small as Cliffe, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we look at the surrounds with you and agree what needs doing.
- We rake out the old mastic and clean the joint.
- 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.
- The finish is dressed so it sits neatly against the stone or brick.
Getting ready for the visit
- Clear items away from the joints we’re working on
- Try not to wet indoor joints just before the visit
- Mention if the joints have been sealed before

Advice
Sand mastic in Cliffe
Our applicators renew the sand mastic around sash and case windows and doors set in stone or brick. Out comes the old, loose mastic, and new mastic is applied and shaped by hand. Common call-outs are for mastic that needs renewing before redecorating and old sand mastic that has cracked, crumbled or fallen out, across timber door frames, sash and case windows and tenement windows.
Outdoor sealant needs dry, clean surfaces, so work on frames around Cliffe is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
You are covered for a year from the day we finish. If there’s a problem with it, please call 0345 464 0079 or drop us an email.

Your questions about sand mastic in Cliffe
Can you help a landlord with a rental near Higham station?
Yes, we work for landlords and letting agents. Just call 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear quote.
Does the coastal weather in Cliffe affect outside sealant?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
Is it OK to seal over old sealant?
No. We remove every bit of old sealant first.
Can I choose the sealant colour?
We help you choose a colour that suits, from white and clear to greys and other shades. The choice depends on the product the joint needs.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you don’t need to watch us work.
Is consent needed for window work on a listed home?
Speak to your local planning authority before work starts. Sand mastic is often favoured as like for like, but they decide.
Are you fully insured?
Yes, we’re fully insured for every job we do.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint before resealing.

DIY sealant or a professional job?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
Leave it or put it right?
Filling over old, loose mastic doesn’t last. Raking out and preparing the joint gives it a sound base so the new mastic stays put. Where a wall is exposed, as many are in small places like Cliffe, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
The cost depends on the size of the job, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts, so you know where you stand.

Looking after it afterwards
Joint life depends on how it’s used and looked after. We suggest:
- Don’t paint over the new mastic
- Keep sills and gutters clear so water drains away
- Find out about consent before window work on a listed home
- Do not run silicone over sand mastic
Look at the mastic when you look over the windows. Catching cracks early keeps repairs small.
Good mastic helps keep the frame dry. Failed mastic lets water reach the timber and timber that stays wet can rot.

Cliffe homes and the weather
Cliffe is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. Historic houses like Temple Manor (about 4.9 miles south) are a reminder that the area around Cliffe has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Rented homes near Higham station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about. In the older streets around Church of St Helen, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Schools such as St Helen's Church of England Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.
