Winchelsea Sand Mastic
Window and door surrounds in Winchelsea need attention? We cut out the old, prepare the joints and apply the right sealant.
- Cement or filler used on old window joints that has cracked
- Crumbling sand mastic round a window
- Mastic worn away on windows facing the weather
The process
A visit follows a simple pattern: we look at the joints together, protect the area around them, carry out the job and tidy away. It generally takes a few hours per window, depending on the condition of the joints. In a small place like Winchelsea, access is normally the main thing to plan. 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.
- Old, loose mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic is not too thick.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- We dress the surface so it sits neatly against the masonry.
How to prepare
- Tell us if parking is tricky
- Try not to wet indoor joints just before the visit
- Tell us about any water getting in

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.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Why act early in Winchelsea
Not every filler suits an old window surround. Sand mastic is the like-for-like choice and that can be important for listed homes. Where a wall is exposed, as many are in small places like Winchelsea, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
What it costs depends on the amount of work, how hard the old material is to remove and access to the work. We give a clear quote before work begins, so you know where you stand.
Why book with us
- Over 20 years’ experience
- A 12-month guarantee on all work
- Homes, businesses and hotels
- Full insurance on every job

Frames and glazing around Winchelsea
Winchelsea is within about 2 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. With historic houses such as Lamb House (about 2 miles north-east) nearby, there’s older building stock in the area around Winchelsea as well as newer homes. 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.
Rented homes near Winchelsea station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out. Managing a site like St Thomas' Church of England Aided Primary School? Then the mastic around its windows and doors needs looking after like any other building’s. In the older streets around The Parish Church of St Thomas the Martyr, the joint between an old wall and a newer frame is generally the first place rain gets in.

What affects the quote in Winchelsea
Your quote is based on your job. We look at:
- Which sealant suits the joint
- The size of the job
- Any working-time requirements on site
- Whether the work is at height
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
Asking for a quote
There’s no need for technical detail. It helps if you can tell us:
- Pictures of the joints, sent by email
- How we’d reach the joints
- The rough size of the job
- Where the property is
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we’ll talk you through what we’d do. When it suits you, ring 0345 464 0079 or drop us an email.

Yes, we work for letting agents and landlords. You can call 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before any work starts.
Do you cover smaller places like Winchelsea?
Yes. Winchelsea is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Is it OK to seal over old sealant?
No. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Is the work guaranteed?
Every job comes with our one-year guarantee, and we are fully insured.
Is it worth trying it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Will it make a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
How much does sand mastic cost in Winchelsea?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
