Do you need sand mastic in High Salvington?
Water gets into small cracks in the mastic and loosens it further. Windows facing the weather tend to go first.
The problems people normally mention when they call are:
- Old cement repairs round a window that have failed
- Mastic dropping out of the joint
- Draughts and rain around sash boxes
- Mastic worn away on windows facing the weather
For an older house near a landmark such as St Peter, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

How we handle sand mastic in High Salvington
Sand mastic does not last for ever and gaps open up round the frame. We rake it out and renew it and tidies the surround. If you have open joints round the window box and wind and rain getting in round a sash window, we can put it right, on tenement windows, timber door frames and brick reveals alike.
Many houses in smaller places like High Salvington have conservatories, garden rooms or patio doors. Those joints need the same attention as the main windows, and any older timber or sash windows need a sealant that suits them.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

What sealant work can’t fix
Sealant is not the answer to every problem, and we will tell you before we start. It won’t solve:
- Broken panes
- Rotten sashes, sills or window boxes (a joiner’s job)
- Whether work needs listed building consent
Not sure which it is? You can phone 0345 464 0079 or email us and we’ll tell you honestly before booking.
What we seal
- Period & listed homes
- Sash and case windows
- Brick reveals
- Stone surrounds
- Timber door frames
- Tenement windows
Different surfaces, different methods
Brick reveals
We rake out the old mastic and pack deep voids before the new mastic goes in.
Period and listed homes
Materials matter on listed and conservation-area homes. Sand mastic is often the preferred finish.
Work for landlords, hotels and businesses
Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we will quote.
Windows and doors in High Salvington
Historic houses like Ecclesden Manor (about 3.1 miles south-west) are a reminder that the area around High Salvington has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. 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.
Letting a property close to Durrington-On-Sea station? Then older sash windows in a rental need their mastic kept sound to keep the weather out. Managing a site like Vale School? Then larger buildings have plenty of frames, and the mastic around each one ages.

How it works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours per window, depending on the condition of the joints. In a smaller place like High Salvington, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- 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.
- We dress the finish so it sits neatly against the masonry.
Before we arrive
- For business premises, tell us about site rules or sign-in
- Where the joints are inside, avoid wetting them before we arrive
- Plan for the work area to be out of bounds to pets and children

How we quote for sand mastic
We quote each job individually. This is what makes a difference:
- Any working-time requirements on site
- Whether old sealant or filler has to be cut out
- The number and length of the joints
- The type of sealant required
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
Helping us quote
When you call or email, it’s useful to know:
- How many joints, rooms or windows are involved
- Whether it has been sealed before
- The address or postcode of the job
- Photos by email, if that’s easy
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints.

DIY sealant or a professional job?
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 fails, we can still redo it.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
