Our applicators work in Angmering-on-Sea on traditional burnt sand mastic around sash and case windows and doors in stone and brick. Old sealant removed completely, joints prepared properly and a one-year guarantee.

- Failed mastic on an exposed elevation
Sand mastic in Angmering-on-Sea
Sand mastic doesn’t last for ever and gaps open up round the frame. Renewing it closes the gap so the surround looks right again. Common call-outs are for old cement repairs round a window that have failed and silicone on a period window that looks wrong, on period & listed homes, stone surrounds and sash and case windows.
In a village or hamlet like Angmering-on-Sea, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
A one-year guarantee comes with the work, just as it does everywhere we cover.

What we do, step by step
On the day, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before we start. Most jobs take a few hours per window, depending on the condition of the joints. In a small place like Angmering-on-Sea, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- 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.
How to prepare
- Tell us about any previous sealing or DIY attempts
- Tell us about access, such as stairs, a lift or high-level joints
- Try not to wet indoor joints just before the visit

Why deal with it now?
Silicone might seem the quicker option, but it can look wrong on a period surround. Sand mastic is the traditional material and finishes neatly against the masonry. Older cottages and farmhouses around Angmering-on-Sea can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed. Ask us for a quote and we’ll explain what it covers.

Sand mastic in Angmering-on-Sea: local notes
Angmering-on-Sea is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you let a flat or house near Angmering station, cracked sand mastic around sash windows lets in the draughts tenants complain about. For site and facilities teams at buildings such as East Preston Infant School, the mastic around its windows and doors needs looking after like any other building’s.

Common questions in Angmering-on-Sea
Is Angmering-on-Sea within the area you cover?
Yes. Angmering-on-Sea is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is sand mastic in a coastal place like Angmering-on-Sea any different?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Is sand mastic better than silicone for my windows?
We will help you decide. Period homes often look best with sand mastic and newer frames suit modern sealant.
Do you work for letting agents?
Yes. As well as householders, we work for landlords, agents, businesses and hotels.
Can old silicone round a sash window be swapped for sand mastic?
Yes. We remove the silicone and clean the joint before the sand mastic goes in.
Do I have to be there?
We need access to the joints, so we will agree that with you when we book. Indoors, that usually means someone at home.
Are you ARBOMaster approved?
Yes. We’re approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
Is there any odour?
That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Signs you need sand mastic in Angmering-on-Sea
Water gets into small cracks in the mastic and loosens it further. Exposed elevations usually fail first.
Signs it’s time to call us include:
- Gaps where the frame meets the masonry
- Wind and rain getting in round a sash window
- Mastic dropping out of the joint
- A silicone bead on a sash window that spoils the look
Homes close to The Parish Church of St Mary include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Before booking anyone
- How much experience the applicator has
- Whether they seal over old material or remove it
- Whether the sealant suits the joint
- Whether they’re fully insured
