Sand mastic for homes and businesses in Burlow
We renew sand mastic around sash windows and doors in stone and brick. Out comes the old, loose mastic, and new mastic is applied and shaped by hand. Common call-outs are for modern sealant on a period surround and failed mastic on an exposed elevation, across period & listed homes, brick reveals and sash and case windows.
Homes in small places like Burlow 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 not left on your own once the job is done.

DIY versus a professional finish
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
What happens if it’s left?
Filling over old, loose mastic does not last. Raking out and preparing the joint gives it a sound base so the new work lasts. Where a wall is exposed, as many are in small places like Burlow, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.

Common problems we fix in Burlow
Decorating can disturb tired mastic. It’s often found when windows are being prepared for paint, which is a good time to renew it.
Signs it’s time to call us include:
- Old sand mastic that has cracked, crumbled or fallen out
- A silicone bead on a sash window that spoils the look
- Mastic round period door frames that has failed
- Gaps where the frame meets the masonry
In and around Burlow, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.

Sand mastic in Burlow: local notes
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Horselunges Manor (about 2.8 miles south) nearby, there’s older building stock in the area around Burlow as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
In the older streets around Christ Church, the joint between an old wall and a newer frame is normally the first place rain gets in.

Keeping the joints in good condition
A little care helps the new joints last. Our advice:
- Avoid heavy scraping on the mastic joint
- Do not paint over the new mastic
- Renew mastic before redecorating the windows
- Avoid patching sand mastic with silicone
Leave the new mastic unpainted, which is the traditional advice. If you are redecorating, ask us first.
Fine cracks show the mastic is starting to fail. Renewing it then is simpler than waiting until it falls out.
Common questions in Burlow
Can you do sand mastic in Burlow?
Yes. We work across London and the South East, and Burlow is part of that. Just phone 0345 464 0079 or drop us an email with a few details of the job.
Is there a guarantee on sand mastic in Burlow?
Every job comes with our 12-month guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
What’s sand mastic made of?
Sand mastic is a traditional material for pointing round windows and doors. It combines sand with a linseed-oil-based binder.
Is there any odour?
There can be a smell while the sealant cures, but it fades. Opening a window helps.
Do you have insurance?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Which products do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice.
Can tenants book the work?
Yes, but check with your landlord or agent first. Landlords are often happy for the work to be arranged.
How much does sand mastic cost in Burlow?
We don’t publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
What we do, step by step
Most of a good job is in the preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours for a single window, longer for several. In a small place like Burlow, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
- 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.
Getting ready for the visit
- Let us know if you’ve seen damp or leaks
- Mention any sign-in or site rules at work premises
- Tell us about access, such as stairs, a lift or high-level joints
