How we handle sand mastic in Mundon
Sand mastic skins over fairly quickly but full hardening takes longer. Traditional guidance is not to paint over it and we’ll advise if you are redecorating. If you have gaps where the frame meets the masonry and mastic dropping out of the joint, we can put it right, on period & listed homes, sash and case windows and brick reveals alike.
Mastic can only go onto a dry, clean joint, so window work in Mundon is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
There’s a 12-month guarantee on every job.

DIY sealant or a professional job?
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

What we are called out for in Mundon
Shallow joints are a common cause. Mastic that is too thin cracks and drops out so we make sure the new mastic is the right thickness.
Any of these means the joints need attention:
- Cracked mastic round a front door frame
- Draughty sash windows at the surround
- Crumbling sand mastic round a window
- Old cement repairs round a window that have failed
If you let a flat or house near North Fambridge station, any sash windows need sound mastic to keep draughts and rain out.

Your questions about sand mastic in Mundon
Can you help a landlord with a rental near North Fambridge station?
Yes, we work for landlords and agents. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before work begins.
Is Mundon within the area you cover?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Is there any odour?
Some sealants have a smell while they cure. Opening a window helps.
Are you an approved applicator?
Yes. We are an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
Do you work for hotels and businesses?
Yes. Commercial and hotel work is a large part of what we do. Working times can be discussed when we quote.
Can I add another job to the visit?
Yes, we can. More than one area can go on one quote.
How long does sand mastic take to harden?
A skin forms quite soon, but full hardening takes longer. We’ll explain what to expect before we leave.
Can you match the sealant colour?
Normally, yes. Sealants come in white, clear, grey and other colours for many products, and we’ll agree it with you first.
How the visit works
Before we leave, we go over the finished joints with you and tell you how long to leave it. The visit itself usually takes a few hours per window, depending on the condition of the joints, depending on the amount of work. For a village or hamlet like Mundon, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We check the window surrounds and agree which joints need renewing.
- 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.
How to prepare
- Let us know about earlier repairs to the joints
- Let us know about stairs, lifts or work at height
- For business premises, tell us about site rules or sign-in

Advice
Why it’s worth doing now in Mundon
Gaps round a sash window let in rain and draughts. Water can get to the frame and the masonry, so dealing with it now protects both. In a small place like Mundon, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.

What else we do in Mundon
Mundon homes and the weather
Mundon is within about 2 miles of 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. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you live in an older home near St Mary's Church, the joint between an old wall and a newer frame is usually the first place rain gets in.
