Sand mastic in Woodside Green
Sand mastic skins over fairly quickly but full hardening takes longer. Traditional guidance is not to paint over it, so ask us before you decorate. If you are dealing with cracked mastic round a front door frame and a silicone bead on a sash window that spoils the look, we can put it right.
In a village or hamlet like Woodside Green, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.
Every job is covered by our one-year guarantee.

How the visit works
Most of a good job is in the preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. In total, it generally takes a few hours for a single window, longer for several. In a small place like Woodside Green, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we agree which joints need doing.
- We remove the old, loose mastic.
- We pack any deep voids first.
- The sand mastic is mixed and pressed into the joint by hand.
- We dress the finish so it sits neatly against the masonry.
How to prepare
- Let us know about earlier repairs to the joints
- Clear items away from the joints we are working on
- Tell us about any water getting in

What else we do in Woodside Green
Signs you need sand mastic in Woodside Green
Shallow joints are a common cause. Mastic that is too thin cracks and drops out, which is why we pack deep voids first and get the depth right.
Any of these means the joints need attention:
- Gaps round a timber door in stone or brick
- Draughts and rain around sash boxes
- Open joints round the window box
- Tired mastic found when preparing windows for paint
Letting a property close to Lenham station? Then older sash windows in a rental need their mastic kept sound to keep the weather out.
Questions to ask before booking
- Whether the sealant suits the joint
- Who does the work, and how experienced they are
- Is VAT in the price?
- What happens if they find a problem under the old sealant
Different surfaces, different methods
Tenement and terrace windows
In shared buildings, the windows may be part of a wider repair, so check who is responsible first.
Period and listed homes
Materials matter on listed and conservation-area homes. Sand mastic is often the preferred finish.
Windows and doors in Woodside Green
Historic houses like Leeds Castle (about 4.3 miles west) are a reminder that the area around Woodside Green has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Schools such as The Lenham School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. For an older house near a landmark such as St Mary's Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

What exactly is sand mastic?
Sand plus a binder based on linseed oil. It’s applied by hand and finished to sit neatly against the masonry.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Do you do commercial work?
Yes. We can plan bigger jobs in stages to suit the site.
How much does sand mastic cost in Woodside Green?
Size, access and the old material all affect the cost. Call for a quick quote.
Should I try it myself first?
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.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
When it isn’t the sealant
We will not take on work that will not last, so these are the limits:
- Decayed frames that need repair
- Masonry that needs repairing
- Sashes that rattle, stick or will not open
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we’ll tell you honestly before booking.
