Can I do it myself?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
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.
How we handle sand mastic in Beech
Burnt sand mastic is a traditional material that sits naturally against stone and brick. It’s a good fit for period properties where a modern sealant bead would stand out. We work on brick reveals, period & listed homes and stone surrounds, and people most often call us about a silicone bead on a sash window that spoils the look and mastic worn away on windows facing the weather.
In a village or hamlet like Beech, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.

What sand mastic looks like in Beech
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Bentworth Hall (about 1.5 miles west) are a reminder that the area around Beech has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Letting a property close to Alton station? Then cracked sand mastic around sash windows lets in the draughts tenants complain about. In the older streets around St Peter's, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

How it works
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours per window, depending on the condition of the joints. For a village or hamlet like Beech, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- 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.
- The surface is finished to suit the stone or brick.
Preparing for the visit
- Let us know about stairs, lifts or work at height

Advice
When it is not the sealant
New sealant can’t fix everything, and we’d rather say so up front. It won’t solve:
- Timber that has rotted
- Broken panes
- Masonry that needs repairing
Not sure which it is? You can call 0345 464 0079 or email us and we’ll tell you honestly before booking.

Is it possible to take out silicone and use sand mastic instead?
Yes, we do this often. All the old silicone is removed first so the mastic beds in well.
Should I use sand mastic or silicone?
We will help you decide. Period homes often look best with sand mastic and newer frames suit modern sealant.
Can you match the sealant colour?
We’ll suggest a colour to suit the surroundings. The product needed can limit the range.
Do you hold any approvals?
Yes. We’re an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.

Is consent needed for window work on a listed home?

What to tell us for a quote
There’s no need for technical detail. Just tell us:
- What’s wrong with the joints now
- How we’d reach the joints
- Photos by email, if that is easy
- Where the property is

Keeping the joints in good condition
After the cure time, these simple habits help:
- Leave the new mastic unpainted
- Renew mastic before redecorating the windows
- Go gently near the mastic when preparing windows
- Have rotten timber repaired before new mastic goes in
Check the mastic when you check the paintwork. Small cracks are easier to deal with early.
Renewing mastic before redecorating saves doing it twice. Painting over failed mastic hides the problem for a while.
