Sand mastic for sash & case windows in Chigwell Row, Essex
Window and door surrounds in Chigwell Row need attention? We cut out the old, prepare the joints and apply the right sealant, and the work is guaranteed for a year.

- Mastic dropping out of the joint
- Gaps between timber frames and stone or brick
About our sand mastic in Chigwell Row
Old sand mastic cracks, crumbles and falls out over time, leaving gaps round the window. Renewing it closes the gap and tidies the surround. If you are dealing with crumbling sand mastic round a window and open joints round the window box, we can help, on period & listed homes, sash and case windows and timber door frames alike.
Mastic can only go onto a dry, clean joint, so window work in Chigwell Row is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
You’re covered for a year from the day we finish. If anything isn’t right with it, call 0345 464 0079 or email us.

DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

What sand mastic looks like in Chigwell Row
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. With historic houses such as Valentines Mansion (about 3.9 miles south-west) nearby, there’s older building stock in the area around Chigwell Row 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.
If you let a flat or house near Chadwell Heath station, older sash windows in a rental need their mastic kept sound to keep the weather out. For an older house near a landmark such as All Saints Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Common problems we fix in Chigwell Row
Shallow joints are a common cause. A thin layer doesn’t hold well, which is why we pack deep voids first and get the depth right.
Most people get in touch when they notice something like this:
- Mastic that needs renewing before redecorating
- Patchy fillers round a sash window
- Failed mastic on an exposed elevation
- Gaps between timber frames and stone or brick
Managing a site like Chigwell Row Infant School? Then larger buildings have plenty of frames, and the mastic around each one ages.

How it works
Most of a good job is in the preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. In total, it usually takes anything from a few hours to a full day, depending on how many windows. Somewhere as small as Chigwell Row, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by checking each surround and agreeing the joints to renew.
- The loose and crumbling mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- We dress the surface so it sits neatly against the masonry.
Preparing for the visit
- Let us know if you’ve seen damp or leaks
- Tell us about any previous sealing or DIY attempts
- On commercial sites, let us know about site rules

Chigwell Row: your questions answered
Do you work for landlords with property near Chadwell Heath station?

Is Chigwell Row in your area for sand mastic?
Yes, Chigwell Row 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, and we’ll give you a clear quote.
What is sand mastic?
It’s sand mixed with a linseed-oil-based binder for the joint between timber frames and masonry.
How long does sand mastic take to go off?
It skins over fairly quickly but takes longer to harden fully. We will explain what to expect before we leave.
Are you ARBOMaster approved?
Yes. We’re approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us.
What do you put in the joint?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we will tell you what we’re using.
How long does sand mastic take?
As a guide, most jobs take a few hours for a single window, longer for several. Larger jobs naturally take longer, and we’ll tell you how long to expect.
What happens if it’s left?
If you’re redecorating, renew the mastic first. Painting over failed mastic does not seal it, and the new mastic is traditionally left unpainted. Where a wall is exposed, as many are in small places like Chigwell Row, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.

What affects the quote in Chigwell Row
Some jobs are bigger than they look, and some smaller. The main factors:
- How many areas need sealing
- The number and length of the joints
- Mould in or behind the old joints
- How much old sealant there is and how hard it is to remove
Instead of a standard rate, 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.
What we need to know
When you call or email, these details help:
- What the problem is, such as mould, gaps, leaks or cracking
- If it’s domestic, commercial or a hotel
- A few pictures by email, if you can
- Any previous sealing or DIY work
Getting a quote is simple: let us know what needs doing and where, and roughly how big it is. A few photos by email make the job easier to understand, and we will come back to you with a quote.
How to look after the new joints
Aftercare is simple:
- Leave the new mastic unpainted
- Clear gutters so water doesn’t pour onto the windows
- Go gently near the mastic when preparing windows
- Check with your local planning authority if your home is listed
Check the mastic when you check the paintwork. Small cracks are easier to deal with early.
Small cracks are a sign the mastic is ageing. It’s easier to renew it before it drops out.
