Sand mastic for sash & case windows in Brightling, East Sussex

Sand mastic in Brightling, done properly
A silicone bead around a sash window can look out of place and does not suit the building. Sand mastic is the traditional choice, and we can replace one with the other. Typical jobs include draughty sash windows at the surround and mastic that needs renewing before redecorating, on sash and case windows, stone surrounds and brick reveals.
Around Brightling, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
Whatever the size of the job, it’s backed by our one-year guarantee.

Common questions in Brightling

Do you cover Brightling for sand mastic?

Do you offer different sealant colours?
We help you choose a colour that suits, from white and clear to greys and other shades. The product needed can limit the range.
Are you ARBOMaster approved?
Yes. We’re an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
Do I have to be there?
That depends on where the joints are. Inside work needs someone to give us access, and for outside work we will agree access with you when we book.
Is sand mastic better than silicone for my windows?
It depends on the window. On many period windows, sand mastic looks right and suits the building and newer frames usually get a flexible sealant.

Keeping the joints in good condition
So the new joints stay in good condition:
- Check with your local planning authority if your home is listed
- Ask a joiner to look at soft timber first
- Leave the new mastic unpainted
- Take care around the mastic when scraping paint
Keep paint scrapers and sanders off the mastic when redecorating. Hard scraping can loosen it.
Small cracks are a sign the mastic is ageing. It’s easier to renew it before it drops out.
Quotes for sand mastic in Brightling
Jobs vary more than people expect. The main factors:
- Any working-time requirements on site
- Mould in or behind the old joints
- Whether the work is at height
- The size of the job
We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please call 0345 464 0079 or drop us an email and we’ll talk you through it.
What we need to know
There’s no need for technical detail. It helps if you can tell us:
- If it’s domestic, commercial or a hotel

DIY versus a professional finish
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
Why it’s worth doing now in Brightling
Draughts round a sash window aren’t always the sashes. Open mastic joints round the box can let air in and new mastic seals them. Older cottages and farmhouses around Brightling can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first and give you a clear quote before any work starts.
Why us?
- Domestic, commercial and hotel work

How the visit works
Every visit runs the same way: we check the joints, protect the area around them, carry out the job and tidy away. Most jobs take a few hours for a single window, longer for several.

We bring what the job needs, so it can be finished in one trip where possible.
- We start by checking each surround and agreeing the joints to renew.
- We rake out the old mastic and clean the joint.
- We pack any deep gaps so the mastic sits at the right depth.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The mastic is finished to sit tidily against the stone or brick.

What sand mastic looks like in Brightling
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Bateman's (about 1.9 miles north-west) are a reminder that the area around Brightling has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
