About our sand mastic in Chipstead
Our applicators renew the sand mastic around sash and case windows and doors in stone and brick. Out comes the old, loose mastic, and new mastic is applied and shaped by hand. We work on brick reveals, sash and case windows and stone surrounds, and common reasons people get in touch are draughts and rain around sash boxes and cracked mastic round a front door frame.
London homes have every kind of window, from timber sashes in period terraces to aluminium and uPVC in newer blocks. The mastic around them dries out and cracks with age, letting in draughts and water.
All of our work is guaranteed for twelve months.

Do you need sand mastic in Chipstead?
Decorating can disturb tired mastic. Many people find it crumbling when they prepare the windows, which is a good time to renew it.
People generally contact us after spotting something like this:
- Modern sealant on a period surround
- Draughts and rain around sash boxes
- Patchy fillers round a sash window
- Gaps where the frame meets the masonry
If you look after a building such as Chipstead Valley Primary School, the mastic around its windows and doors needs looking after like any other building’s.
What your quote should include
- How much experience the applicator has
- What insurance they hold
- Whether you can choose the colour
- Whether the sealant suits the joint
Why deal with it now?
New mastic over crumbling mastic will not hold. Raking out and preparing the joint gives it a sound base so the new mastic stays put. In London conversions, one flat’s bathroom is often above another flat’s ceiling, and a slow leak from a failed seal can end up in the flat below. Dealing with it early is far simpler for homes in Chipstead.
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we will go through it with you.
Why us?
- Any old sealant cut out fully, not covered over
- Approved under the ARBOMaster scheme
- Fully insured
- Domestic, commercial and hotel work

Sand mastic in Chipstead: local notes
In London conversions and blocks, the lease decides who is responsible for the frames, so it’s worth checking before booking. Historic houses like Nonsuch Mansion (about 4.5 miles north-west) are a reminder that the area around Chipstead 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.
If you let a flat or house near Chipstead station, cracked sand mastic around sash windows lets in the draughts tenants complain about. For an older house near a landmark such as Church of St Margaret, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

How the visit works
There is not much for you to do on the day. Point us to the joints and we’ll get on with it. The job generally takes a few hours per window, depending on the condition of the joints. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. Mention any building rules, key holders or managing agents when you book.
- We check each window surround and the condition of the joint.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic isn’t too thick.
- New sand mastic is applied and shaped by hand.
- The finish is dressed neatly.
Preparing for the visit
- Clear items away from the joints we are working on
- Let us know about parking restrictions
- Mention any leaks or damp you’ve noticed

Advice
Surface by surface
Sash and case windows
The mastic round a sash window is on show, so a neat, even finish matters.
Stone surrounds
The stone is treated with care while raking out the old mastic.
DIY sealant or a professional job?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
If you are 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.

FAQs for Chipstead
Can you do sand mastic in Chipstead?
Yes, Chipstead is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or drop us an email and let us know what needs doing, and we’ll send you a clear quote.
Is parking a problem for a job in Chipstead?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot.
Should I try DIY first?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Is it possible to take out silicone and use sand mastic instead?
Often, yes. With the silicone removed and the joint cleaned we point it with sand mastic.
I’m a tenant. Can you help?
Of course. Ask your landlord first, and we can send them the quote if that helps.
Do you have insurance?
Yes. We’re fully insured.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you don’t need to watch us work.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Landlord and commercial work in Chipstead
