About our sand mastic in Rushenden
Fresh sand mastic forms a skin quite soon but full hardening takes longer. Traditionally, sand mastic is left unpainted and we will advise if you are redecorating. If you are dealing with cement or filler used on old window joints that has cracked and weathered mastic on the most exposed windows, we can help, whatever the surface.
Homes in small places like Rushenden often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

What else we do in Rushenden
What sand mastic looks like in Rushenden
Rushenden is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on the mastic around older windows and doors, especially on the side facing the sea. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Rented homes near Queenborough station change hands often, and any sash windows need sound mastic to keep draughts and rain out. If you look after a building such as Queenborough School and Nursery, the mastic around its windows and doors needs looking after like any other building’s.
Rushenden is about 2 miles south-west of Sheerness, in Kent. Rushenden gets the same service as everywhere we cover: the old material taken out, joints prepared properly and a 12-month guarantee.

What affects the quote in Rushenden
You will get a clear quote before we start. It takes into account:
- Working hours on commercial sites
- Access and height
- The number of rooms or windows
- Whether old sealant or filler has to be cut out
Instead of a standard rate, 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.
What to tell us for a quote
What to tell us when you ask for a quote:
- Whether it’s a home or a business
- How many joints, rooms or windows are involved
- The problem you’ve noticed
- Pictures of the joints, sent by email
We quote each job on its own. Simply phone 0345 464 0079 or drop us an email and describe the job and send photos if you have them.
How to look after the new joints
No joint lasts for ever, but care makes a real difference. Our tips:
- Renew mastic before redecorating the windows
- Do not paint over the new mastic
- Make sure water runs off the sill
- Keep modern sealant off the mastic
Leave the new mastic unpainted, as traditional guidance advises. Ask us before any decorating around it.
Gaps round a sash box let in draughts and rain. Left, the gap tends to get bigger.
When it isn’t the sealant
We won’t take on work that won’t last, so these are the limits:
- Putty and glazing repairs
- Decayed frames that need repair
- Sash cords, weights and draught-proofing of the sashes
Not sure which it is? You can ring 0345 464 0079 or send us an email and we’ll tell you honestly before booking.
Surfaces we seal
- Period & listed homes
- Brick reveals
- Sash and case windows
- Tenement windows
- Stone surrounds
- Timber door frames
Why deal with it now?
Cement-based fillers and modern sealants don’t always suit a period surround. Sand mastic matches what was there, which can matter on listed and conservation-area homes. Around Rushenden, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
What it costs depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before any work starts, so you know where you stand.
Why us?
- Every job guaranteed for a year
- Anti-fungal sanitary silicone in wet areas
- ARBOMaster approved applicator
- We are fully insured

Signs you need sand mastic in Rushenden
Over the years, sand mastic weathers. It dries out, cracks and loses its grip from the frame or the masonry.
It’s worth asking for a quote if you see:
- Old sand mastic that has cracked, crumbled or fallen out
- Cement or filler used on old window joints that has cracked
- Mastic that needs renewing before redecorating
- A silicone bead on a sash window that spoils the look
In the older streets around Parish Church of the Holy Trinity, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
Questions to ask before you book
- Whether they seal over old material or remove it
- Who does the work, and how experienced they are
- Is VAT in the price?
- How hidden problems are handled
Can I do it myself?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
How it works
At the end, we look at the finished work together and explain the cure time. The visit itself generally takes a few hours per window, depending on the condition of the joints, depending on the size of the job. Somewhere like Rushenden needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We check each window surround and the condition of the joint.
- We rake out the old mastic and clean the joint.
- Large voids are packed out.
- New sand mastic is applied and shaped by hand.
- We finish the mastic to a tidy line.
How to prepare
- Let us know about earlier repairs to the joints
- Clear the area around the work
- On commercial sites, let us know about site rules
