Common questions in Tendring Heath
Is Tendring Heath in your area for sand mastic?
Yes, Tendring Heath is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or email us with a few details of the job.
Can you help a landlord with a rental near Weeley station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises. Working times can be discussed when we quote.
Can I paint the new mastic?
Sand mastic is normally left unpainted, which is what traditional guidance recommends. Ask us before decorating.
Is it worth trying it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Is it messy?
No. We protect the surfaces around the joints, and we tidy up before we go.
Do you guarantee sand mastic work?
Our 12-month guarantee applies to all our work.
How long does sand mastic take to harden?
It forms a skin fairly soon and it hardens fully over a longer time. The weather and joint depth both affect it.
How the visit works
A visit follows a simple pattern: we check the joints, protect the area around them, carry out the job and clear up. Most jobs take a few hours per window, depending on the condition of the joints. For a village or hamlet like Tendring Heath, the journey is planned in advance: 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 the window surrounds and agree which joints need renewing.
- We rake out the old mastic and clean the joint.
- Large voids are packed out first, so the mastic isn’t 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.
Getting ready for the visit
- Try not to wet indoor joints just before the visit
- Tell us about any previous sealing or DIY attempts
- Keep children and pets away from the work area

What sealant work cannot fix
Some problems need a builder, plumber or other trade rather than us:
- Rotten sashes, sills or window boxes (a joiner’s job)
- Putty and glazing repairs
- Decisions on consent for listed homes
If in doubt, ring 0345 464 0079 or email us and we’ll say what we think.
Surfaces we seal
- Stone surrounds
- Tenement windows
- Sash and case windows
- Timber door frames
- Brick reveals
- Period & listed homes
Leave it or put it right?
Draughts round a sash window aren’t always the sashes. Open mastic joints round the box can let air in, and renewing the mastic closes them. Older cottages and farmhouses around Tendring Heath can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
What it costs depends on the size of the job, how much old material has to come out and access to the work. You will have a clear quote before any work starts, so you know where you stand.

What affects the quote in Tendring Heath
The price is agreed before any work begins. It takes into account:
- When we can work, for business premises
- The size of the job
- The old material and how stubborn it is
- The type of sealant required
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
Helping us quote
To make quoting easier, please include:
- How we’d reach the joints
- Where the property is
- The problem you’ve noticed
- The type of property
If you are in Tendring Heath and need sand mastic, ring 0345 464 0079 or send us an email. Tell us what the problem is and where, and we will agree the price before any work begins.
Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
Tendring Heath homes and the weather
With historic houses such as Thorpe Hall (about 4.2 miles south-east) nearby, there’s older building stock in the area around Tendring Heath as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For an older house near a landmark such as Church of St Mary, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Rented homes near Weeley station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about.
