Garlinge Sand Mastic
We cover Garlinge for traditional burnt sand mastic around sash and case windows and doors in stone and brick. Old material cut out, joints cleaned and sealed neatly.
- Draughts and rain around sash boxes
- Modern sealant on a period surround
- Cement or filler used on old window joints that has cracked
Why act early in Garlinge
New mastic over crumbling mastic will not hold. Raking out and preparing the joint gives it a sound base so the new work lasts. In an older home around Garlinge, damp from a failed joint can get into timber and plaster, and that’s a much bigger job than renewing the sealant.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we will explain what it covers.
Why us?
- Approved under the ARBOMaster scheme
- More than 20 years in sealant work
- Domestic, commercial and hotel work
- Old sealant always removed completely

About our sand mastic in Garlinge
Sand mastic suits most period window surrounds. On modern frames we’d normally use a flexible sealant, and we’ll talk through which suits your home. We’re often asked to deal with weathered mastic on the most exposed windows and a silicone bead on a sash window that spoils the look, across tenement windows, period & listed homes and stone surrounds.
Many houses in smaller places like Garlinge have conservatories, garden rooms or patio doors. Their glazing joints and frame seals are as much a part of the job as the windows.
You get a 12-month guarantee, the same in Garlinge as everywhere else we work.

Looking after it afterwards
To keep the joints looking good and working properly:
- Ask us before painting near the mastic
- Sort the mastic before the decorators arrive
- Avoid heavy scraping on the mastic joint
- Check the mastic when you check the paintwork
Avoid sealing over the mastic with silicone. If you see a crack, ask us to take a look rather than patching it.
Sound mastic protects the frame. Once it fails, water can sit against the timber, which can lead to rot.

Questions from Garlinge
Is sand mastic in a coastal place like Garlinge any different?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. Walls facing the sea are generally the first to need attention.
Is Garlinge within the area you cover?
Yes. Garlinge is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is it worth trying it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
Are you insured?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
When will the new mastic be hard?
It forms a skin fairly soon and it hardens fully over a longer time. The weather and joint depth both affect it.
Should I use sand mastic or silicone?
It depends on the window. Period windows in stone or brick usually suit sand mastic, while modern frames normally get a flexible sealant.
How long does the job take?
It depends on the size of the job, but most jobs take a few hours per window, depending on the condition of the joints. We will tell you when we quote.
Where do you work from?
We are based in Crawley, and we cover South East England, London and all of Scotland.
Windows and doors in Garlinge
Garlinge is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on the mastic around older windows and doors, especially on the side facing the sea. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Letting a property close to Margate station? Then cracked sand mastic around sash windows lets in the draughts tenants complain about. For an older house near a landmark such as St James, frames set in older brick or stone need a sealant that suits the wall as well as the frame. If you look after a building such as Garlinge Primary School and Nursery, the mastic around its windows and doors needs looking after like any other building’s.

Different surfaces, different methods
Timber door frames
Sand mastic is used round timber door frames too. We renew it the same way as on windows.
Sash and case windows
Most of our sand mastic work is on sash windows. Each joint round the box is raked out and renewed.
Should I try it myself first?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
How we quote for sand mastic
We do not publish a price list, because jobs vary so much. What we look at:
- Working hours on commercial sites
- Whether the work is at height
- The number and length of the joints
- Any mould that needs treating
We don’t show prices on the website, because each job is priced on what it involves. Call for a quick quote and we will talk you through it.
What we need to know
There’s no need for technical detail. It helps if you can tell us:
- How many joints, rooms or windows are involved
- A few photos by email, if you can
- How we’d reach the joints
- If it’s domestic, commercial or a hotel
For a quote, ring 0345 464 0079 or drop us an email and tell us where the job is and what the problem looks like. You’ll have a clear quote before we start.
The process
You don’t need to clear the whole room or building before we come, just the space around the work. Everything nearby is protected, and the work takes a few hours for a single window, longer for several for a typical job. A visit to Garlinge is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We check each window surround and the condition of the joint.
- We rake out the old mastic and clean the joint.
- Large voids are packed out.
- New sand mastic is applied and shaped by hand.
- We finish the mastic to a tidy line.
How to prepare
- Plan for the work area to be out of bounds to pets and children
- Mention any sign-in or site rules at work premises
- Move anything stored near the joints
