About our sand mastic in Rowhedge
Silicone on a period window often looks wrong and isn’t always the right material. Sand mastic is the traditional choice and we can swap the silicone for it. If you have mastic round period door frames that has failed and draughts and rain around sash boxes, we can help, on stone surrounds, period & listed homes and brick reveals alike.
Many houses in smaller places like Rowhedge have conservatories, garden rooms or patio doors. Their glazing joints and frame seals are as much a part of the job as the windows, and any older timber or sash windows need a sealant that suits them.
Our work is backed for twelve months.

Signs you need sand mastic in Rowhedge
Timber frames move with the seasons. The movement cracks the mastic over time.
Most people get in touch after spotting something like this:
- Cement or filler used on old window joints that has cracked
- Mastic that needs renewing before redecorating
- Mastic round period door frames that has failed
- Mastic worn away on windows facing the weather
For an older house near a landmark such as Church of St Lawrence, the joint between an old wall and a newer frame is generally the first place rain gets in.

- What guarantee comes with the work
- Which colour the sealant will be
Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. Our tips:
- Ask the planning authority about consent for listed or conservation-area homes
- Avoid heavy scraping on the mastic joint
- Inspect the joints round the windows every year or so
- Make sure water runs off the sill
Look at the mastic when you look over the windows. Small cracks are easier to deal with early.
Fine cracks show the mastic is starting to fail. Renewing it then is simpler than waiting until it falls out.
How we quote for sand mastic
The price is agreed before any work begins. It’s based on:
- Whether old sealant or filler has to be cut out
- Which sealant suits the joint
- When we can work, for business premises
- How many rooms, windows or areas are involved
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.
What to tell us for a quote
Before you ask for a quote, have a think about:

FAQs for Rowhedge
Can you help a landlord with a rental near Wivenhoe station?
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.
Does the coastal weather in Rowhedge affect outside sealant?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Do you have insurance?
Yes, we’re fully insured for every job we do.
Can I choose the sealant colour?
Most of the time, yes. We’ll explain which colours are available and agree one before work begins.
What sealant do you use?
Products from Arbo and Everbuild, among others, picked for each joint. We’ll tell you what we’re using and why.
Can old silicone round a sash window be swapped for sand mastic?
In most cases. We remove the silicone and clean the joint, then point it with sand mastic.
Which is right for my windows, sand mastic or modern sealant?
We’ll help you decide. Sand mastic suits many period homes, and modern sealants suit newer frames.
What does sand mastic cost?
Size, access and the old material all affect the cost. Call for a quick quote.
Honest limits
New sealant cannot fix everything, and we’d rather say so up front. It will not solve:
- Crumbling stone or brickwork round the window
- Rotten sashes, sills or window boxes (a joiner’s job)
- Putty and glazing repairs
If in doubt, phone 0345 464 0079 or email us and we’ll say what we think before booking.
Surfaces we seal
- Brick reveals
- Timber door frames
- Period & listed homes
- Tenement windows
- Sash and case windows
- Stone surrounds
Why deal with it now?
Before painting the windows, it pays to renew the mastic. Paint over cracked mastic won’t stop the gaps and traditional guidance is to leave the new mastic unpainted. In a smaller place like Rowhedge, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we’ll explain what it covers.
Why book with us
- We are fully insured
- Old sealant always removed completely
- 20+ years of sealant experience
- Approved under the ARBOMaster scheme

Sand mastic in Rowhedge: local notes
Rowhedge is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on the mastic around older windows and doors, especially on the side facing the sea. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Managing a site like St Lawrence Church of England Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages. Letting a property close to Wivenhoe station? Then cracked sand mastic around sash windows lets in the draughts tenants complain about.

The process
Most of a good job is in the preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes anything from a few hours to a full day, depending on how many windows. Parking around Rowhedge is generally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- First we agree which joints need doing.
- We remove the old, loose mastic.
- We pack any deep voids first.
- The sand mastic is mixed and pressed into the joint by hand.
- The surface is finished to suit the stone or brick.
How to prepare
- Clear items away from the joints we are working on
- Mention if the joints have been sealed before
- Let us know about stairs, lifts or work at height
