Aylesford Sand Mastic
We cover Aylesford 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 and every job guaranteed for a year.
- Gaps where the frame meets the masonry
- Mastic worn away on windows facing the weather
- Draughty sash windows at the surround
How we handle sand mastic in Aylesford
Our applicators renew the sand mastic around sash and case windows and doors in stone and brick. Out comes the old, loose mastic, and new mastic is applied and shaped by hand. We are often asked to deal with gaps round a timber door in stone or brick and failed mastic on an exposed elevation, across sash and case windows, stone surrounds and tenement windows.
In a smaller place like Aylesford, some walls face open ground and catch the full force of the weather, so exposed windows and doors face the weather head on. The mastic around frames on those walls tends to age faster.
Whatever the size of the job, you get the same 12-month guarantee in Aylesford and across Kent.

Aylesford questions
Is Aylesford within the area you cover?
Yes, Aylesford is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can you help a landlord with a rental near Aylesford station?
Yes. We work for letting agents and landlords as well as homeowners. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear price.
How much does sand mastic cost in Aylesford?
Size, access and the old material all affect the cost. Ask us for a quote.
Is sand mastic better than silicone for my windows?
We’ll help you decide. Period homes often look best with sand mastic and newer frames suit modern sealant.
Can old silicone round a sash window be swapped for sand mastic?
Yes, it’s a common request. The old silicone has to come out completely so the mastic can sit properly.
Can sand mastic be painted?
The usual advice is to leave sand mastic unpainted. Ask us before you decorate around it and we’ll advise.
Do I need to be at home?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that normally means someone at home.
Do you do commercial work?
Yes, regularly. Larger jobs can be planned room by room or area by area.
Keeping the joints in good condition
How long the joints last depends on use and care. We suggest:
- Do not paint over the new mastic
- Have rotten timber repaired before new mastic goes in
- Sort the mastic before the decorators arrive
- Don’t run silicone over sand mastic
Make sure water drains away from the window surround. Constant wetting wears the mastic faster.
An open joint round the box lets weather through. The longer it’s left, the more the joint opens.

Should I try it myself first?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Sand mastic in Aylesford: local notes
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Starkey Castle (about 4.5 miles north) nearby, there’s older building stock in the area around Aylesford as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Rented homes near Aylesford station change hands often, and any sash windows need sound mastic to keep draughts and rain out. Schools such as Aylesford Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. For an older house near a landmark such as Aylesford Church, the joint between an old wall and a newer frame is normally the first place rain gets in.

What we do, step by step
You do not need to clear the whole room or building before we come, only the area right around the joints. We protect the rest, and the job takes anything from a few hours to a full day, depending on how many windows in most cases. In a smaller place like Aylesford, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- First, we look at the surrounds with you and agree what needs doing.
- We rake out the old mastic and clean the joint.
- 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 finish is dressed so it sits neatly against the stone or brick.
How to prepare
- Keep children and pets away from the work area
- Let us know about stairs, lifts or work at height
- Mention any parking rules near the property
