Sand mastic in Hook
Sand mastic skins over fairly quickly but full hardening takes longer. Traditional guidance is not to paint over it and we’ll advise if you’re redecorating. If you have patchy fillers round a sash window and failed mastic on an exposed elevation, we can help, on sash and case windows, timber door frames and brick reveals alike.
In a smaller place like Hook, some walls face open ground and catch the full force of the weather, so exposed windows and doors face the weather head on. The mastic around frames on those walls tends to age faster.
Each job carries a 12-month guarantee, large or small.

Hook homes and the weather
With historic houses such as Stratfield Saye House (about 4.8 miles north) nearby, there’s older building stock in the area around Hook as well as newer homes. 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, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Homes close to St John the Evangelist include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Rented homes near Hook station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about.

DIY sealant or a professional job?
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. All the old material has to come out first.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
Different surfaces, different methods
Sash and case windows
The box of a sash and case window sits in the stone or brick opening. Sand mastic seals the joint round it.
Tenement and terrace windows
Tenements and terraces often have many sash windows with ageing mastic. We work on single windows or whole elevations.

What we do, step by step
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, carry out the job and clear up. It normally takes anything from a few hours to a full day, depending on how many windows. In a smaller place like Hook, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- First, we look at the surrounds with you and agree what needs doing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- 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.
Getting ready for the visit
- Let us know about stairs, lifts or work at height
- Keep pets and children clear of the area while we work

Why it’s worth doing now in Hook

Keeping the joints in good condition
After the cure time, these simple habits help:
- Clear gutters so water doesn’t pour onto the windows
- Ask us before painting near the mastic
- Ask a joiner to look at soft timber first
- Renew mastic before redecorating the windows
Check the mastic when you check the paintwork. Small cracks are easier to deal with early.
Sound mastic protects the frame. Once it fails, water can sit against the timber, which can lead to rot.
