- Silicone on a period window that looks wrong
- Gaps where the frame meets the masonry
- Gaps round a timber door in stone or brick
How to look after the new joints
Simple care keeps the joints in good condition. Our advice:
- Make sure water runs off the sill
- Plan mastic work ahead of painting
- Go gently near the mastic when preparing windows
- Leave the new mastic unpainted
Do not run silicone over the new mastic. If you see a crack, ask us to take a look before trying a quick fix.
Sound mastic protects the frame. Once it fails, water can sit against the timber and timber that stays wet can rot.
Sand mastic in Heybridge, done properly
Burnt sand mastic is a traditional material that sits naturally against stone and brick. It’s a good fit for period properties, where modern sealant can look out of place. Typical jobs include cracked mastic round a front door frame and open joints round the window box, across brick reveals, tenement windows and stone surrounds.
Around Heybridge, conservatories, garden rooms and patio doors are often part of the house. Their glazing joints and frame seals are as much a part of the job as the windows.
You’re covered for a year from the day we finish. If anything is not right with it, call 0345 464 0079 or drop us an email.

DIY sealant or a professional job?
If you do try it yourself, take your time over the 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.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Heybridge homes and the weather
Heybridge is close to 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. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you live in an older home near Church of St Andrew, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Rented homes near Hatfield Peverel station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about.

Leave it or put it right?
If you are redecorating, renew the mastic first. Painting over failed mastic doesn’t seal it and traditional guidance is to leave the new mastic unpainted. Around Heybridge, water from a failed joint in an older home can soak into timber and plaster, and that’s a much bigger job than renewing the sealant.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.

Signs you need sand mastic in Heybridge
Age is the main cause. Sand mastic is a maintenance item like any pointing, depending on exposure and upkeep.
If you can see any of these, it’s time to have the joints looked at:
- Modern sealant on a period surround
- Window mastic to renew ahead of painting
- Draughty sash windows at the surround
- Patchy fillers round a sash window
For site and facilities teams at buildings such as Heybridge Primary School, larger buildings have plenty of frames, and the mastic around each one ages.
Questions to ask before booking
- What the quote includes, VAT included or not
- Are they insured?
- Who does the work, and how experienced they are
- Whether they seal over old material or remove it
What we do, step by step
We keep the work tidy and contained to the joints we are treating, so you can get on with your day. The job generally takes anything from a few hours to a full day, depending on how many windows. A visit to Heybridge is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- First, we look at the surrounds with you and agree what needs doing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic is not too thick.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us about any water getting in
- Let us know about earlier repairs to the joints

What’s sand mastic made of?
Sand mastic is a traditional material for pointing round windows and doors. It’s made with sand and a linseed-oil-based binder.
Can you seal over the old sealant?
No. New silicone will not bond to old silicone, and it traps any mould or water underneath. We remove it all first.
