Sand Mastic in Wainscott
Professional sand mastic in and around Wainscott, with every bit of old sealant taken out first and a 12-month guarantee.
- Tired mastic found when preparing windows for paint
- Gaps between timber frames and stone or brick
- Cement or filler used on old window joints that has cracked
When to call us in Wainscott
Sand mastic slowly weathers. It dries out, cracks and loses its grip on the stone or timber.
Any of these means the joints need attention:
- Silicone on a period window that looks wrong
- Draughty sash windows at the surround
- Open joints round the window box
- Failed mastic on an exposed elevation
If you live in an older home near St Philip & St James, the joint between an old wall and a newer frame is usually the first place rain gets in.

About our sand mastic in Wainscott
We work across Wainscott renewing sand mastic on sash windows and doors. Every joint is cleaned out and filled by hand, finished to suit the masonry. We work on tenement windows, sash and case windows and timber door frames, and the jobs we see most are modern sealant on a period surround and old cement repairs round a window that have failed.
In a smaller place like Wainscott, some walls face open ground and catch the full force of the weather. The mastic around frames on those walls tends to age faster.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Questions from Wainscott
Can you help a landlord with a rental near Strood station?
Yes. We work for letting agents and landlords as well as homeowners. You can ring 0345 464 0079 or email us with the details for a clear quote.
Will you come out to Wainscott?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Is it OK to seal over old sealant?
No, it won’t last. It may look fine at first, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Do you work for hotels and businesses?
Yes. Larger jobs can be planned room by room or area by area.
Do you have insurance?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Can I choose the sealant colour?
In most cases you can choose. We’ll tell you which colours the right product comes in and agree one before work begins.
Will there be a smell?
It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.
How long does sand mastic take to go off?
It takes a while. It skins first and hardens fully later, and we’ll tell you what to expect.

- Putty and glazing repairs

What happens on the day
Good joint work is mostly preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. In total, it generally takes anything from a few hours to a full day, depending on how many windows. A visit to Wainscott is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- Deep gaps are packed so the mastic sits at the right depth.
- We apply the mastic by hand and shape it.
- The surface is finished to suit the stone or brick.
Before we arrive
- Let us know about parking restrictions
- For indoor joints, keep the area dry beforehand if you can
- Let us know about stairs, lifts or work at height

Windows and doors in Wainscott
Wainscott 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. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. With historic houses such as Restoration House (about 1.7 miles south) nearby, there’s older building stock in the area around Wainscott as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
For landlords with property near Strood station, cracked sand mastic around sash windows lets in the draughts tenants complain about. Managing a site like Wainscott Primary School? Then the mastic around its windows and doors needs looking after like any other building’s.

Can I do it myself?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Why deal with it now?
New mastic over crumbling mastic will not hold. We remove the loose material first so the new work lasts. In a smaller place like Wainscott, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
