Sand mastic for homes and businesses in Norwood End
We renew sand mastic around sash windows and doors set in stone or brick. Out comes the old, loose mastic, the joint is prepared and new mastic is shaped by hand. We work on timber door frames, stone surrounds and period & listed homes, and the jobs we see most are draughts and rain around sash boxes and window mastic to renew ahead of painting.
Around Norwood End, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
Big or small, you get the same 12-month guarantee in Norwood End and across Essex.

Norwood End homes and the weather
London and the South East are among the drier parts 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 Nicholas, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. For site and facilities teams at buildings such as The Ongar Academy, the mastic around its windows and doors needs looking after like any other building’s.

What the job involves on each surface
Tenement and terrace windows
Where a building is shared, window work may involve neighbours so it’s worth checking responsibilities.
Timber door frames
Doors face weather and wear, so their mastic can fail sooner. It’s renewed by hand.
Can I do it myself?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.
Why deal with it now?
Gaps round a sash window let in rain and draughts. Left, water can reach the timber and the wall so renewing it early protects the window. Around Norwood End, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
What it costs depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before work begins.

Quotes for sand mastic in Norwood End
The price is agreed before any work begins. It’s based on:
- The number and length of the joints
- When we can work, for business premises
- How much old sealant there is and how hard it is to remove
- The number of rooms or windows
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, call 0345 464 0079 or email us for an honest opinion and a quote.
Asking for a quote
To make quoting easier, let us know:
- Roughly how big the job is
- The address or postcode of the job
- What’s wrong with the joints now
- If it’s domestic, commercial or a hotel
For a quick quote, get us on the phone, or email us if that’s easier. Describe what needs sealing and we will talk you through the work.
Looking after it afterwards
To keep the joints looking good and working properly:
- Avoid heavy scraping on the mastic joint
- Don’t run silicone over sand mastic
- Ask the planning authority about consent for listed or conservation-area homes
- Ask a joiner to look at soft timber first
Leave the new mastic unpainted, as traditional guidance advises. Ask us before any decorating around it.
An open joint round the box lets weather through. The longer it’s left, the more the joint opens.
How it works
A visit follows a simple pattern: we check the joints, protect the area around them, carry out the job and tidy away. Most jobs take a few hours per window, depending on the condition of the joints.

- We start by checking each surround and agreeing the joints to renew.
- We rake out the old mastic and clean the joint.
- Deep voids are packed so the mastic is the right thickness.
