For landlords and businesses
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. We can quote for more than one property at once.
From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
Sand mastic in Hollington, done properly
Fresh sand mastic forms a skin quite soon but full hardening takes longer. Traditionally, sand mastic is left unpainted, so ask us before you decorate. Typical jobs include silicone on a period window that looks wrong and open joints round the window box, on period & listed homes, stone surrounds and timber door frames.
Mastic can only go onto a dry, clean joint, so window work in Hollington is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
There’s a 12-month guarantee on every job, whatever its size.

Frames and glazing around Hollington
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Stargroves (about 0.8 miles north-west) nearby, there’s older building stock in the area around Hollington as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
If you live in an older home near Church of St Thomas, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Schools such as St Thomas' Church of England Infant School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

Hollington: your questions answered
Will you come out to Hollington?
Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Do you cover Hollington for sand mastic?
Yes. Our work covers London and the South East, and Hollington is part of that. You can phone 0345 464 0079 or email us and tell us what needs doing, and we’ll give you a clear price.
What should I tell you?
A short description and the location. If we need more, we will ask.
What is sand mastic?
It’s a mix of sand and a linseed-oil-based binder. It’s built up in the joint by hand and finished to sit neatly against the masonry.
Do you do commercial work?
Yes, regularly. We can plan bigger jobs in stages to suit the site.
How long does the job take?
A typical job takes a few hours per window, depending on the condition of the joints. We will confirm how long when we quote.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
How much does sand mastic cost in Hollington?
Size, access and the old material all affect the cost. Ask us for a quote.
How it works
On the day, there’s very little for you to do. Show us the job and we will take it from there. The work itself takes a few hours per window, depending on the condition of the joints. For a village or hamlet like Hollington, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by checking each surround and agreeing the joints to renew.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The finish is dressed so it sits neatly against the stone or brick.
Preparing for the visit
- Clear the area around the work
- Mention any parking rules near the property
- For indoor joints, keep the area dry beforehand if you can

Related advice
What we are called out for in Hollington
Some old mastic was never deep enough. Mastic that’s too thin cracks and drops out so we make sure the new mastic is the right thickness.
It’s worth asking for a quote if you see:
- Open joints round the window box
- Tired mastic found when preparing windows for paint
- Old sand mastic that has cracked, crumbled or fallen out
- Wind and rain getting in round a sash window
For landlords with property near Kintbury station, older sash windows in a rental need their mastic kept sound to keep the weather out.

DIY sealant or a professional job?
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, then guaranteed for a year.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
How to look after the new joints
Simple care keeps the joints in good condition. Our advice:
- Have rotten timber repaired before new mastic goes in
- Take care around the mastic when scraping paint
- Don’t paint over the new mastic
- Sort the mastic before the decorators arrive
Avoid painting over the new mastic, as traditional guidance advises. If you are redecorating, ask us first.
Once mastic starts to crumble, rain gets in. It can soak into the frame and the surrounding masonry so early renewal protects both.
