We work on stone surrounds, tenement windows and brick reveals, and the jobs we see most are a silicone bead on a sash window that spoils the look and wind and rain getting in round a sash window.

How to look after the new joints
Aftercare is simple, and it makes a real difference:
- Inspect the joints round the windows every year or so
- Keep sills and gutters clear so water drains away
- Ask a joiner to look at soft timber first
- Don’t paint over the new mastic
Leave the new mastic unpainted, which is the traditional advice. Ask us before any decorating around it.
Sound mastic protects the frame. Once it fails, water can sit against the timber, which can lead to rot.

Leave it or put it right?
Draughts round a sash window are not always the sashes. Gaps between the frame and the wall can be just as bad, and renewing the mastic closes them. Older cottages and farmhouses around Brown Candover can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first.

Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Which products do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice.
Do you work for landlords and businesses?
Yes, often. We can quote for several properties at once.
Will it make a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Is it OK to seal over old sealant?
No. Fresh sealant does not stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.
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. Somewhere like Brown Candover needs a little journey planning: 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.
- We check the window surrounds and agree which joints need renewing.
- We rake out the old mastic and clean the joint.
- Large voids are packed out first, so the mastic is not too thick.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The mastic is finished to sit tidily against the stone or brick.
How to prepare
- Let us know about earlier repairs to the joints
- Let us know about stairs, lifts or work at height
- Let us know if you’ve seen damp or leaks
