FAQs for Turners Hill
Can you help a landlord with a rental near East Grinstead station?
Yes. We work for landlords and letting agents as well as householders, and several properties can be quoted together. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we will send you a clear quote.
Will you come out to Turners Hill?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you guarantee sand mastic work?
Our 12-month guarantee applies on every job.
Which is right for my windows, sand mastic or modern sealant?
For period timber windows in stone or brick, sand mastic is often the better fit. Modern frames normally suit a flexible sealant, and we will explain why.
Is it possible to take out silicone and use sand mastic instead?
Yes, it’s a common request. The old silicone has to come out completely so the mastic can sit properly.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Should I try DIY first?
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.
Is it messy?
We keep the work tidy. Nearby surfaces are protected, and we clear up when we’re done.
Sand mastic in Turners Hill, done properly
Our applicators renew the sand mastic around sash and case windows and doors in stone and brick. Out comes the old, loose mastic, the joint is prepared and new mastic is shaped by hand. We work on timber door frames, brick reveals and period & listed homes, and common reasons people get in touch are mastic that needs renewing before redecorating and silicone on a period window that looks wrong.
Homes in small places like Turners Hill often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Landlords, agents and businesses in Turners Hill
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
What sealant work can’t fix
Before booking, it’s worth knowing the limits:

- Cracked or broken glass

We bring what the job needs, so it can be finished in one trip where possible.
- We check each window surround and the condition of the joint.
- We rake out the old mastic and clean the joint.
- We fill deep gaps so the new mastic isn’t too thick.

Advice
DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
What we’re called out for in Turners Hill
Timber frames move with the seasons. That movement opens up the mastic joint little by little.
If you can see any of these, it’s time to have the joints looked at:
- Draughty sash windows at the surround
- Cement or filler used on old window joints that has cracked
- Mastic dropping out of the joint
- Weathered mastic on the most exposed windows
Schools such as Turners Hill CofE Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

Looking after it afterwards
So the new joints stay in good condition:
- Clear gutters so water does not pour onto the windows
- Inspect the joints round the windows every year or so
- Ask a joiner to look at soft timber first
- Renew mastic before redecorating the windows
Avoid painting over the new mastic, as traditional guidance advises. If you are redecorating, ask us first.
An open joint round the box lets weather through. The longer it’s left, the more the joint opens.
Turners Hill homes and the weather
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Gravetye Manor (about 1.6 miles south-east) nearby, there’s older building stock in the area around Turners Hill as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
Rented homes near East Grinstead station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about. If you live in an older home near Church of St Leonard, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
