Coleman's Hatch Sand Mastic
Professional sand mastic in and around Coleman's Hatch, with old sealant always removed completely.
- Draughty sash windows at the surround
- Open joints round the window box
- Tired mastic found when preparing windows for paint
The process
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a few hours per window, depending on the condition of the joints and we leave things clean and tidy. Somewhere as small as Coleman's Hatch, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at the surrounds with you and agree the joints to renew.
- We remove the old, loose mastic.
- We pack any deep voids first.
- We apply the mastic by hand and shape it.
- The surface is finished to suit the stone or brick.
Getting ready for the visit

Sand mastic in Coleman's Hatch
If your home is listed or in a conservation area, check with your local planning authority if consent is needed before window work. Sand mastic is often favoured as a like-for-like material. If you have gaps between timber frames and stone or brick and cracked mastic round a front door frame, we can help, whatever the surface.
Mastic can only go onto a dry, clean joint, so window work in Coleman's Hatch is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
We stand behind the work with a 12-month guarantee, so you’re covered after we have gone.

How we quote for sand mastic
The price is agreed before any work begins. It’s based on:
- Whether the work is at height
- How much old sealant there is and how hard it is to remove
- Working hours on commercial sites
- The number of rooms or windows
Homes and businesses are quoted the same way: the amount of work, the access and the products needed. Call for a quick quote and we will explain what it covers.
Asking for a quote
When you contact us, it’s useful to know:
- A few pictures by email, if you can
- Where the job is, and your postcode
- How many joints, rooms or windows are involved
- Whether it’s a home or a business
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is. When it suits you, ring 0345 464 0079 or drop us an email.

Coleman's Hatch: your questions answered
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 go on one quote. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Is Coleman's Hatch within the area you cover?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can I do it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Can new sealant go over the old?
No, it won’t last. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
How long does the job take?
Most jobs take anything from a few hours to a full day, depending on how many windows. We’ll confirm how long when we quote.
Does someone need to be in?
We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.
Can you do several jobs on one visit?
Of course. Combining jobs makes good use of the visit.
Are you an approved applicator?
Yes. Mr Mastic is an ARBOMaster approved applicator and we are fully insured too.

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Sort the mastic before the decorators arrive
- Get any rot dealt with first
- Don’t paint over the new mastic
- Look over the window mastic once a year
Keep paint scrapers and sanders off the mastic when redecorating. Hard scraping can loosen it.
Once mastic starts to crumble, rain gets in. It can soak into the frame and the surrounding masonry so early renewal protects both.

What else we do in Coleman's Hatch
Common problems we fix in Coleman's Hatch
Timber frames move with the seasons. The movement cracks the mastic over time.
If you can see any of these, it’s time to have the joints looked at:
- Draughts and rain around sash boxes
- Open joints round the window box
- Mastic that needs renewing before redecorating
- Gaps round a timber door in stone or brick
Rented homes near East Grinstead station change hands often, and any sash windows need sound mastic to keep draughts and rain out.
What your quote should include
- Is VAT in the price?
- What product goes in the joint
- What insurance they hold
- How the surfaces are prepared before sealing
Sand mastic in Coleman's Hatch: local notes
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Bassetts Manor (about 2.6 miles north-east) nearby, there’s older building stock in the area around Coleman's Hatch 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.
Homes close to Holy Trinity Church include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Leave it or put it right?
An open joint round the frame lets weather in. Water can get to the frame and the masonry, so dealing with it now protects both. Where a wall is exposed, as many are in small places like Coleman's Hatch, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we will explain the quote if you ask.
