Leave it or put it right?
If you’re redecorating, renew the mastic first. Paint over cracked mastic will not stop the gaps and traditional guidance is to leave the new mastic unpainted. Where a wall is exposed, as many are in small places like Norton Heath, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you’re unsure, phone 0345 464 0079 or send us an email for an honest opinion and a quote.

How long does sand mastic take?
Typically it takes anything from a few hours to a full day, depending on how many windows. Larger jobs naturally take longer, and we’ll say how long yours will take.
Where are you based?
Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.
When will the new mastic be hard?
The surface skins quite quickly and it hardens fully over a longer time. Timing depends on the weather and the joint.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference.
Do I have to be there?
If the work is inside, we need someone to let us in. Once we have agreed the job, you don’t need to watch us work.
What the job involves on each surface
Timber door frames
Door frames get knocked and soaked and the mastic can crack early. We rake it out and renew it.
Stone surrounds
The stone is treated with care when the old mastic comes out.
Windows and doors in Norton Heath
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Ingatestone Hall (about 4.8 miles south-east) nearby, there’s older building stock in the area around Norton Heath as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
If you let a flat or house near Ingatestone station, cracked sand mastic around sash windows lets in the draughts tenants complain about. If you live in an older home near Church of All Saints, frames set in older brick or stone need a sealant that suits the wall as well as the frame. For site and facilities teams at buildings such as Blackmore Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

How it works
You don’t need to clear the whole room or building before we come, only the area right around the joints. Everything nearby is protected, and the job takes a few hours per window, depending on the condition of the joints in most cases. Somewhere like Norton Heath needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by checking each surround and agreeing the joints to renew.
- Old, loose mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The mastic is finished to sit tidily against the stone or brick.
Before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- Keep children and pets away from the work area
- Where the joints are inside, avoid wetting them before we arrive

Advice
How we quote for sand mastic
Some jobs are bigger than they look, and some smaller. What affects the quote:
- How easy the joints are to reach
- How much there is to do
- When we can work, for business premises
- How much old sealant there is and how hard it is to remove
Doing several joints on one visit is normally more efficient than separate visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.
Asking for a quote
To help us quote quickly, please include:
- The type of property
- What the problem is, such as mould, gaps, leaks or cracking
- Where the property is
- A few photos by email, if you can
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and add pictures by email if you can.
Aftercare tips
Good habits help new joints last longer. A few tips:
- Avoid patching sand mastic with silicone
- Ask the planning authority about consent for listed or conservation-area homes
- Inspect the joints round the windows every year or so
- Renew mastic before redecorating the windows
Leave the new mastic alone while it firms up. It skins over quickly, but takes longer to harden fully.
Gaps round a sash box let in draughts and rain. The longer it’s left, the more the joint opens as more mastic falls out.
