How we handle sand mastic in Rook End
Silicone on a period window often looks wrong and does not suit the building. 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 mastic that needs renewing before redecorating and mastic dropping out of the joint.
In a village or hamlet like Rook End, 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.
A 12-month guarantee comes as standard, so you’re not left on your own once the job is done.

How the job changes by surface
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.
Brick reveals
Gaps between frame and brick let in rain and draughts. Renewing the mastic closes it.

Rook End homes and the weather
Historic houses like Horham Hall (about 2.9 miles south-east) are a reminder that the area around Rook End has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For site and facilities teams at buildings such as Joyce Frankland Academy, its window and door frames need their mastic kept sound, just like a home’s. If you live in an older home near Church of St Mary and All Saints, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Rented homes near Newport (Essex) station change hands often, and any sash windows need sound mastic to keep draughts and rain out.

Aftercare tips
Aftercare is simple:
- Get any rot dealt with first
- Keep modern sealant off the mastic
- Inspect the joints round the windows every year or so
- Ask us before painting near the mastic
Don’t run silicone over the new mastic. If anything cracks, get it looked at rather than patching it.
Small cracks are a sign the mastic is ageing. Renewing it then is simpler than waiting until it falls out.

Is it worth trying it myself?
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 remove the old sealant?
Yes, always, and completely. New sealant will not bond properly to old, so the joint is cleaned back first.
Are you fully insured?
Yes. Full insurance covers our work.
Should I check with the council before work on a listed or conservation-area home?
Yes, it’s worth checking. Ask your local planning authority whether consent is needed for listed or conservation-area properties.
How long will you be here?
As a guide, most jobs take anything from a few hours to a full day, depending on how many windows. Larger jobs naturally take longer.
How it works
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and clear up. Most jobs take anything from a few hours to a full day, depending on how many windows. Somewhere as small as Rook End, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by checking each surround and agreeing the joints to renew.
- We rake out the old mastic and clean the joint.
- Deep voids are packed so the mastic is the right thickness.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The finish is dressed so it sits neatly against the stone or brick.
Getting ready for the visit
- Mention any sign-in or site rules at work premises
- Keep pets and children clear of the area while we work
- Mention if the joints have been sealed before

Advice
DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
