FAQs for Furzeley Corner
Does the coastal weather in Furzeley Corner affect outside sealant?
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 usually the first to need attention.
Do you cover smaller places like Furzeley Corner?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you work for hotels and businesses?
Yes. We can plan bigger jobs in stages.
Can sand mastic be painted?
Sand mastic is normally left unpainted, which is what traditional guidance recommends. Ask us before decorating.
Can I do it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Do you have insurance?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint before resealing.
Which is right for my windows, sand mastic or modern sealant?
For period timber windows in stone or brick, sand mastic is often the better fit. Modern frames normally suit a flexible sealant.

Leave it or put it right?
A silicone bead can be quicker, but it can look wrong on a period surround. Sand mastic suits the building and blends with the stone or brick. In a small place like Furzeley Corner, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.

The process
We bring everything the job needs with us, so there’s nothing for you to buy. After a quick look at the joints together, the area is protected and the work begins. It normally takes a few hours per window, depending on the condition of the joints. In a small place like Furzeley Corner, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- We pack any deep voids first.
- The sand mastic is mixed and pressed into the joint by hand.
- We dress the finish so it sits neatly against the masonry.
Getting ready for the visit
- Clear the area around the work
- Let us know about stairs, lifts or work at height
- Plan for the work area to be out of bounds to pets and children

Related advice
Can I do it myself?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
How to look after the new joints
Simple care keeps the joints in good condition. We recommend:
- Ask us before painting near the mastic
- Clear gutters so water does not pour onto the windows
- Avoid patching sand mastic with silicone
- Check the mastic when you check the paintwork
Check the mastic when you check the paintwork. Catching cracks early keeps repairs small.
Crumbling mastic lets rain into the joint. That water can reach the timber frame and the wall so early renewal protects both.
Sand mastic in Furzeley Corner: local notes
Furzeley Corner is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. 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.
Schools such as Denmead Junior School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.
