- Silicone on a period window that looks wrong
- Draughts and rain around sash boxes
- Failed mastic on an exposed elevation
For landlords and businesses
Failed sealant is one of the commonest items on a check-out report. We can quote for more than one property at once.
In hotels, rooms out of use cost money, so the work can be planned room by room. We’ve worked in hotels as well as homes and businesses.
How we handle sand mastic in Mapledurwell
Our applicators renew the sand mastic around sash and case windows and doors set in stone or brick. Out comes the old, loose mastic, and new mastic is applied and shaped by hand. Typical jobs include window mastic to renew ahead of painting and gaps where the frame meets the masonry, on tenement windows, timber door frames and stone surrounds.
Mastic can only go onto a dry, clean joint, so window work in Mapledurwell is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
You get a one-year guarantee, the same in Mapledurwell as everywhere else we work.

What affects the cost of sand mastic
For a quick quote, just ask. The main things that affect it are:
- Working hours on commercial sites
- The size of the job
- How many rooms, windows or areas are involved
- How much old sealant there is and how hard it is to remove
Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you’re unsure, phone 0345 464 0079 or email us for an honest opinion and a quote.

- The address or postcode of the job
Every job is quoted individually, so the first step is telling us about yours. Just ring 0345 464 0079 or email us with the details, and pictures are welcome.
Your questions about sand mastic in Mapledurwell
Will you come out to Mapledurwell?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you do sand mastic in Mapledurwell?
Yes, Mapledurwell is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or send us an email and let us know what needs doing.
Do you take out the old sealant first?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Can you seal over the old sealant?
No, it will not last. It may look fine at first, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Is sand mastic better than silicone for my windows?
We will help you decide. Sand mastic suits many period homes, and modern sealants suit newer frames.
Do I need permission for sand mastic on a listed building?
Yes, it’s worth checking. Ask your local planning authority whether consent is needed for listed or conservation-area properties.
Is it possible to paint over sand mastic?
Traditional guidance is not to paint over sand mastic. Ask us before you decorate around it and we will talk you through it.
What exactly is sand mastic?
It’s the traditional filler for the joint round timber windows and doors. It combines sand with a linseed-oil-based binder.
Aftercare tips
Good habits help new joints last longer. A few tips:
- Leave the new mastic unpainted
- Check the mastic when you check the paintwork
- Renew mastic before redecorating the windows
- Ask a joiner to look at soft timber first
Make sure water drains away from the window surround. Constant wetting wears the mastic faster.
An open joint round the box lets weather through. Left, the gap tends to get bigger as more mastic falls out.
Do you need sand mastic in Mapledurwell?
Age is the main cause. Sand mastic is a maintenance item like any pointing and how long it lasts depends on the weather it faces.
If you can see any of these, it’s time to have the joints looked at:
- Weathered mastic on the most exposed windows
- Tired mastic found when preparing windows for paint
- Old cement repairs round a window that have failed
- Mastic dropping out of the joint
Rented homes near Hook station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about.
Questions to ask before booking
- When the joint can take water or movement
- What guarantee comes with the work
- What happens if the job turns out different
- Who does the work, and how experienced they are
Leave it or put it right?
Silicone might seem the quicker option, but on period stone or brick it often looks out of place. Sand mastic is the traditional material and blends with the stone or brick. Around Mapledurwell, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we’ll explain what it covers.

Frames and glazing around Mapledurwell
With historic houses such as The Vyne (about 4.4 miles north-west) nearby, there’s older building stock in the area around Mapledurwell as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
In the older streets around Church of St. Mary, the joint between an old wall and a newer frame is usually the first place rain gets in.

What happens on the day
Most of a good job is in the preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it generally takes anything from a few hours to a full day, depending on how many windows. In a small place like Mapledurwell, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we look at the surrounds with you and agree what needs doing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic isn’t too thick.
- 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
- Let us know about earlier repairs to the joints
- Where the joints are inside, avoid wetting them before we arrive
- Move anything stored near the joints
