For landlords and businesses
Housing providers, facilities teams and property managers book us too in Durrington and across West Sussex. Several sites can be quoted together, and we are fully insured for the work.

About our sand mastic in Durrington
Old sand mastic cracks, crumbles and falls out over time, leaving gaps round the window. We rake it out and renew it so the surround looks right again. If you’re dealing with mastic dropping out of the joint and draughts and rain around sash boxes, we can help, whatever the surface.
Houses in smaller places like Durrington can stand more in the open than those in a built-up town, so exposed windows and doors face the weather head on. The mastic around frames on those walls tends to age faster.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Should I try it myself first?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
What affects the cost of sand mastic
We don’t publish a price list, because no two jobs are the same. The quote depends on:
- When we can work, for business premises
- Whether old sealant or filler has to be cut out
- The type of sealant required
- How many rooms, windows or areas are involved
The cost depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before work begins, so you know where you stand.
Asking for a quote
When you contact us, it’s useful to know:
- Roughly how big the job is
- A few photos by email, if you can
- Whether it has been sealed before
- What’s wrong with the joints now
If you are in Durrington and need sand mastic, ring 0345 464 0079 or email us. A short description of the job and where it is helps us quote, and we’ll agree the price before any work begins.
What sealant work cannot fix
We won’t take on work that won’t last, so these are the limits:
- Sash cords, weights and draught-proofing of the sashes
- Crumbling stone or brickwork round the window
- Planning or listed building consent (your local planning authority decides)
If in doubt, call 0345 464 0079 or email us and we’ll say what we think.
What we seal
- Sash and case windows
- Stone surrounds
- Brick reveals
- Period & listed homes
- Timber door frames
- Tenement windows
What happens on the day
Every visit runs the same way: we look at the joints together, protect the area around them, do the work and clear up. Most jobs take anything from a few hours to a full day, depending on how many windows. In a smaller place like Durrington, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- First we agree which joints need doing.
- We remove the old, loose mastic.
- Deep gaps are packed so the mastic sits at the right depth.
- The sand mastic is mixed and pressed into the joint by hand.
- The surface is finished to suit the stone or brick.
Getting ready for the visit
- Tell us about any water getting in
- Tell us about any previous sealing or DIY attempts
- Keep pets and children clear of the area while we work
Ask for a quote
Getting a quote is simple: let us know what needs doing and where, and roughly how big it is. Photos by email help us understand the job, and we’ll take it from there.

Aftercare tips
To keep the joints looking good and working properly:
- Look over the window mastic once a year
- Check with your local planning authority if your home is listed
- Sort the mastic before the decorators arrive
- Go gently near the mastic when preparing windows
Keep gutters and sills clear so water runs away from the surround. Constant wetting wears the mastic faster.
Fine cracks show the mastic is starting to fail. Renewing it then is simpler than waiting until it falls out.

Durrington questions
Can you help a landlord with a rental near Durrington-On-Sea station?
Yes, landlords and agents are among the people we work for. You can phone 0345 464 0079 or send us an email with the details for a clear quote.
Does living near the coast affect sand mastic in Durrington?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
Are you ARBOMaster approved?
Yes. We are approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
Is it worth trying it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Is consent needed for window work on a listed home?
Your local planning authority is the one to ask. They’ll tell you if consent is needed for work to your windows.
Can you work on commercial sites?
Yes, regularly. Larger jobs can be planned room by room or area by area.
Can old silicone round a sash window be swapped for sand mastic?
Yes, it’s a common request. All the old silicone is removed first so the mastic beds in well.
Which is right for my windows, sand mastic or modern sealant?
We’ll talk it through with you. Period homes often look best with sand mastic and newer frames suit modern sealant.
Sand mastic in Durrington: local notes
Durrington is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on the mastic around older windows and doors, especially on the side facing the sea. With historic houses such as Ecclesden Manor (about 2.6 miles west) nearby, there’s older building stock in the area around Durrington 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.
Schools such as Durrington Junior School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s. Rented homes near Durrington-On-Sea station change hands often, and any sash windows need sound mastic to keep draughts and rain out. Homes close to St Symphorian's Church include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.
