Sand mastic in Ridgewood
Silicone on a period window often looks wrong and isn’t always the right material. Sand mastic gives a finish that matches the age of the house, and we can replace one with the other. We work on period & listed homes, timber door frames and sash and case windows, and people most often call us about draughts and rain around sash boxes and old sand mastic that has cracked, crumbled or fallen out.
Many houses in smaller places like Ridgewood have conservatories, garden rooms or patio doors. Those joints need the same attention as the main windows.
Big or small, it’s backed by our 12-month guarantee in Ridgewood and across East Sussex.

What sand mastic looks like in Ridgewood
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For site and facilities teams at buildings such as Harlands Primary School, the mastic around its windows and doors needs looking after like any other building’s. If you live in an older home near St Saviour, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

What affects the quote in Ridgewood
For a quick quote, just ask. The main things that affect it are:
- How many areas need sealing
- Whether old sealant or filler has to be cut out
- Whether the work is at height
- Which sealant suits the joint
What it costs depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. You’ll have a clear quote before any work starts, so you know where you stand.

Common questions in Ridgewood
Do you cover Ridgewood for sand mastic?
Yes, Ridgewood is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or send us an email with a few details of the job.
I let a flat near Uckfield station. Can you help?
Yes, we work for letting agents and landlords. Just ring 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear price.
Is it possible to paint over sand mastic?
Traditional guidance is not to paint over sand mastic. If you’re redecorating the window, ask us first and we will advise.
Which products do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we’ll explain our choice.
Can I do it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Which is right for my windows, sand mastic or modern sealant?
Sand mastic usually suits period timber windows best. On modern frames, we’d normally use a flexible sealant.
Can you quote for more than one area?
Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
What’s sand mastic made of?
A traditional pointing material made from sand and a linseed-oil-based binder, used between timber frames and stone or brick.
Different surfaces, different methods
Stone surrounds
We take care not to mark the stone when the old mastic comes out.
Tenement and terrace windows
In shared buildings, the windows may be part of a wider repair, so check who is responsible first.

What else we do in Ridgewood
When to call us in Ridgewood
Some old mastic was never deep enough. A thin layer does not hold well so we make sure the new mastic is the right thickness.
Signs it’s time to call us include:
- Cement or filler used on old window joints that has cracked
- Tired mastic found when preparing windows for paint
- Mastic dropping out of the joint
- Silicone on a period window that looks wrong
If you let a flat or house near Uckfield station, any sash windows need sound mastic to keep draughts and rain out.
What your quote should include
- How the surfaces are prepared before sealing
- What happens if the job turns out different
- How long the guarantee is
- Whether you can choose the colour
The process
Every visit runs the same way: we look at the joints together, protect the area around them, do the work and clear up. It normally takes a few hours for a single window, longer for several. A visit to Ridgewood is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- 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
- Tell us if parking is tricky
- Tell us about any water getting in
- Mention any sign-in or site rules at work premises
Ask for a quote
It all starts with a short chat. Describe the problem, the location and the size of the job, and we’ll explain how we’d tackle it. Whenever you are ready, phone 0345 464 0079 or email us.
Advice
How to look after the new joints
Simple care keeps the joints in good condition. Our advice:
- Have rotten timber repaired before new mastic goes in
- Ask us before painting near the mastic
- Avoid heavy scraping on the mastic joint
- Find out about consent before window work on a listed home
Check the mastic when you check the paintwork. Catching cracks early keeps repairs small.
Fine cracks show the mastic is starting to fail. It’s easier to renew it before it drops out.
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.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
