Sand mastic for homes and businesses in Upper Kingston
Burnt sand mastic is a traditional material that sits naturally against stone and brick. It’s a good fit for period properties where a modern sealant bead would stand out. Typical jobs include mastic dropping out of the joint and gaps where the frame meets the masonry, across timber door frames, brick reveals and sash and case windows.
Mastic can only go onto a dry, clean joint, so window work in Upper Kingston is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
There’s a 12-month guarantee on every job, large or small.

How it works
Most of a good job is in the preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. In total, it generally takes a few hours per window, depending on the condition of the joints. Somewhere like Upper Kingston needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First, we look at the surrounds with you and agree what needs doing.
- We rake out the old mastic and clean the joint.
- Large voids are packed out first, so the mastic is not too thick.
- The mastic is mixed, pressed into the joint by hand and shaped.
- We dress the surface so it sits neatly against the masonry.
Before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- On commercial sites, let us know about site rules
- Keep pets and children clear of the area while we work

Advice
Questions from Upper Kingston
Will you come out to Upper Kingston?
Yes, Upper Kingston is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Is sand mastic in Upper Kingston guaranteed?
Every job comes with our one-year guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.
Do you remove the old sealant?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Do you work for hotels and businesses?
Yes. Commercial and hotel work is a large part of what we do. We can talk about working times when we quote.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Is it possible to take out silicone and use sand mastic instead?
Normally, yes. Once the silicone is out and the joint prepared we point it with sand mastic.
What should I tell you?
The location, the problem and the rough size of the job. Photos by email help too.
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.

Do you need sand mastic in Upper Kingston?
Some old mastic was never deep enough. A thin layer does not hold well, which is why we pack deep voids first and get the depth right.
Most people get in touch after spotting one of these:
- Open joints round the window box
- Failed mastic on an exposed elevation
- Modern sealant on a period surround
- Old sand mastic that has cracked, crumbled or fallen out
Schools such as Ringwood Junior School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.
What your quote should include
- Which sealant they’ll use, and why
- Whether all the old sealant comes out first
- Whether VAT is included
- What the cure time is
How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Check the mastic when you check the paintwork
- Renew mastic before redecorating the windows
- Ask the planning authority about consent for listed or conservation-area homes
- Get any rot dealt with first
Look at the mastic when you look over the windows. Small cracks are easier to deal with early.
An open joint round the box lets weather through. Left, the gap tends to get bigger as more mastic falls out.
DIY versus a professional finish
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

Sand mastic in Upper Kingston: local notes
With historic houses such as Avon Tyrrell House (about 2.6 miles south-east) nearby, there’s older building stock in the area around Upper Kingston as well as newer homes. 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. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
In the older streets around Trinity Congregational Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
