Sand mastic in Wyck
Across Wyck, we renew sand mastic around sash and case windows. Every joint is cleaned out and filled by hand, finished to suit the masonry. We work on sash and case windows, timber door frames and brick reveals, and the jobs we see most are gaps between timber frames and stone or brick and modern sealant on a period surround.
Mastic can only go onto a dry, clean joint, so window work in Wyck is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

Wyck homes and the weather
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 landlords with property near Alton station, any sash windows need sound mastic to keep draughts and rain out. If you live in an older home near Church of St Mary, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

How we quote for sand mastic
The quote reflects the job in front of us. We look at:
- How many rooms, windows or areas are involved
- Whether old sealant or filler has to be cut out
- How easy the joints are to reach
- The number and length of the joints
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we will go through it with you.
Helping us quote
When you contact us, these details help:
- Whether it has been sealed before

When to call us in Wyck
Most of it is simply age. Even well-laid mastic needs renewing in time and how long it lasts depends on the weather it faces.
Signs it’s time to call us include:
- Gaps round a timber door in stone or brick
- Mastic worn away on windows facing the weather
- Tired mastic found when preparing windows for paint
- Modern sealant on a period surround
For site and facilities teams at buildings such as Binsted Church of England Primary School, the mastic around its windows and doors needs looking after like any other building’s.

- Whether all the old sealant comes out first
- What the cure time is
- Whether the sealant suits the joint
When it isn’t the sealant
Sealant isn’t the answer to every problem, and we’d rather say so up front. It will not solve:
- Decisions on consent for listed homes
- Rotten sashes, sills or window boxes (a joiner’s job)
- Damaged stone surrounds
If in doubt, ring 0345 464 0079 or email us and we will say what we think before you book.

FAQs for Wyck
Do you work for landlords with property near Alton station?
Yes, we work for landlords and letting agents. You can phone 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before we start.
Is Wyck in your area for sand mastic?
Yes, Wyck is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or drop us an email with a few details of the job.
Will it make a mess?
No. The area is protected while we work and cleaned up afterwards.
Will the old sealant be removed?
Yes, every time. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
How long will you be here?
It depends on the size of the job, but most jobs take a few hours per window, depending on the condition of the joints. We will give you a better idea when we quote.
Do the sealants smell?
There can be a smell while the sealant cures, but it fades. Ventilation helps.
Where are you based?
Mr Mastic is based in Crawley. Our applicators cover Wyck, along with the rest of our area.
What is sand mastic?
Sand mastic is a traditional material for pointing round windows and doors. It’s made with sand and a linseed-oil-based binder.
DIY versus a professional finish
If you’ve already had a go yourself, that is fine. We cut it out and start again.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.

Advice
How to look after the new joints
Aftercare is simple:
- Get any rot dealt with first
- Avoid patching sand mastic with silicone
- Look over the window mastic once a year
- Check with your local planning authority if your home is listed
When preparing windows for paint, take care around the mastic. It can be damaged by heavy scraping.
Renewing mastic before redecorating saves doing it twice. Paint over cracked mastic only covers it up.
