Your questions about sand mastic in Borden
Do you work for landlords with property near Sittingbourne station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear quote.
Will you come out to Borden?
Yes, Borden is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Which products do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We’ll tell you what we are using and why.
Is it messy?
Not at all. The area is protected while we work and cleaned up afterwards.
Will there be a smell?
That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Will the old sealant be removed?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Do you work for hotels and businesses?
Yes, regularly. We can plan bigger jobs in stages.
What should I tell you?
Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply phone 0345 464 0079 or send us an email.
Sand mastic in Borden
Burnt sand mastic is a traditional material that sits naturally against stone and brick. It suits period and listed homes where a modern sealant bead would stand out. Typical jobs include silicone on a period window that looks wrong and draughts and rain around sash boxes, on brick reveals, timber door frames and period & listed homes.
Homes in small places like Borden often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
We stand behind the work with a one-year guarantee, so you’re covered after we have gone.

What affects the quote in Borden
The price is agreed before any work begins. It’s based on:
- The type of sealant required
- Mould in or behind the old joints
- How many areas need sealing
- Access and height
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re not sure whether it needs doing, call 0345 464 0079 or drop us an email for an honest opinion and a quote.
Helping us quote
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- Photos by email, if that is easy
- The problem you’ve noticed
- How many joints, rooms or windows are involved
- Whether it has been sealed before
Getting a quote is simple: let us know what needs doing and where and its rough size. A few photos by email make the job easier to understand, and we will take it from there.
Landlord and commercial work in Borden
Hotels need rooms back in use, so the work can be planned room by room. We’ve worked in hotels as well as homes and businesses.
Mouldy or split sealant often shows up at the end of a tenancy. Several properties can go on one quote.
Keeping the joints in good condition
Good habits help new joints last longer. A few tips:
- Get any rot dealt with first
- Check the mastic when you check the paintwork
- Go gently near the mastic when preparing windows
- Find out about consent before window work on a listed home
Make sure water drains away from the window surround. Constant wetting wears the mastic faster.
It’s best to renew mastic before painting the windows. Paint over cracked mastic only covers it up.
Windows and doors in Borden
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For landlords with property near Sittingbourne station, any sash windows need sound mastic to keep draughts and rain out. For site and facilities teams at buildings such as Borden Church of England Primary School, its window and door frames need their mastic kept sound, just like a home’s.

What we are called out for in Borden
Sand mastic slowly weathers. It dries out, cracks and loses its grip from the frame or the masonry.
Most people get in touch after spotting something like this:
- Old cement repairs round a window that have failed
- Mastic dropping out of the joint
- A silicone bead on a sash window that spoils the look
- Wind and rain getting in round a sash window
For an older house near a landmark such as Church of St Peter and St Paul, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

What we do, step by step

Expect the work to take a few hours per window, depending on the condition of the joints, and we tell you how long to leave it before we go. Somewhere like Borden needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We start by checking each surround and agreeing the joints to renew.
- Old, loose mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Getting ready for the visit
- Try not to wet indoor joints just before the visit
- Let us know about earlier repairs to the joints
