Sand mastic in Wivenhoe
We renew sand mastic around sash windows and doors in stone and brick. Out comes the old, loose mastic, and new mastic is applied and shaped by hand. If you are dealing with mastic dropping out of the joint and window mastic to renew ahead of painting, we can put it right.
Around Wivenhoe, conservatories, garden rooms and patio doors are often part of the house. Those joints need the same attention as the main windows.
The work is covered for a year after we finish. If there’s a problem with it, please call 0345 464 0079 or send us an email.

Wivenhoe homes and the weather
Wivenhoe is within about 2 miles of 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. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Homes close to The Church of St Mary include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. For site and facilities teams at buildings such as Millfields Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

Quotes for sand mastic in Wivenhoe
Every job gets its own quote. These are the things that affect it:
- Whether old sealant or filler has to be cut out
- How many areas need sealing
- The number and length of the joints
- The product the joint needs
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Helping us quote
When you contact us, these details help:
- Roughly how big the job is
- Photos by email, if that’s easy
- If someone has resealed it before
- If it’s domestic, commercial or a hotel
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and add pictures by email if you can.
The process
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours per window, depending on the condition of the joints. For a job in Wivenhoe, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- First we agree which joints need doing.
- We remove the old, loose mastic.
- Deep gaps are packed so the mastic sits at the right depth.
- The sand mastic is mixed and pressed into the joint by hand.
- We dress the finish so it sits neatly against the masonry.
Getting ready for the visit
- Keep children and pets away from the work area
- Clear the area around the work
- For business premises, tell us about site rules or sign-in

Wivenhoe: your questions answered
Can you help a landlord with a rental near Wivenhoe station?
Yes, landlords and agents are among the people we work for. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear quote.
Does living near the coast affect sand mastic in Wivenhoe?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. Walls facing the sea are usually the first to need attention.
Do you do commercial work?
Yes, regularly. Larger jobs can be planned room by room or area by area.
Is the work guaranteed?
You get our 12-month guarantee to all our work.
Which products do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We’ll tell you what we’re using and why.
Does someone need to be in?
We need access to the joints, so we will agree that with you when we book. Indoors, that normally means someone at home.
Are you insured?
Yes. We are fully insured.
Where is Mr Mastic based?
We are a Crawley-based firm, with over 20 years’ experience. We work across South East England, London and Scotland.
Leave it or put it right?
An open joint round the frame lets weather in. Left, water can reach the timber and the wall, so dealing with it now protects both. Around Wivenhoe, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed. Call for a quick quote and we’ll explain what it covers.

Timber swells and shrinks with the weather. That movement opens up the mastic joint little by little.

- Old cement repairs round a window that have failed
- Gaps between timber frames and stone or brick
- A silicone bead on a sash window that spoils the look
- Crumbling sand mastic round a window
Letting a property close to Wivenhoe station? Then any sash windows need sound mastic to keep draughts and rain out.
What your quote should include

- Whether all the old sealant comes out first
- Whether VAT is included
- What happens if the job turns out different
Can I do it myself?
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’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 fails, we can still redo it.
Different surfaces, different methods
Tenement and terrace windows
Rows of sash windows on tenements and terraces often need renewing together. We can do one window or several.
Period and listed homes
On a listed home or in a conservation area, the right material matters. Like-for-like sand mastic is normally favoured.
