About our sand mastic in Walton-on-the-Naze
Traditional burnt sand mastic blends with stone and brick surrounds. It’s a good fit for period properties where a modern sealant bead would stand out. If you are dealing with old cement repairs round a window that have failed and a silicone bead on a sash window that spoils the look, we can put it right.
Houses in smaller places like Walton-on-the-Naze can stand more in the open than those in a built-up town. The mastic around frames on those walls tends to age faster.
We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

Work for landlords, hotels and businesses
Letting agents and landlords in Walton-on-the-Naze can book us as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
Can I do it myself?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
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.
Why act early in Walton-on-the-Naze
Filling over old, loose mastic does not last. Raking out and preparing the joint gives it a sound base so the new mastic stays put. Homes in smaller places like Walton-on-the-Naze can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

- Every job guaranteed for a year

What we do, step by step
Once we’re on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for a single window, longer for several. For a job in Walton-on-the-Naze, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We check the window surrounds and agree which joints need renewing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic isn’t too thick.
- 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.
Before we arrive
- Let us know about parking restrictions
- Mention any sign-in or site rules at work premises
- Where the joints are inside, avoid wetting them before we arrive

What sand mastic looks like in Walton-on-the-Naze
Walton-on-the-Naze is close to 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. With historic houses such as Thorpe Hall (about 4.2 miles west) nearby, there’s older building stock in the area around Walton-on-the-Naze as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
If you live in an older home near Church of All Saints, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Your questions about sand mastic in Walton-on-the-Naze
Is sand mastic in a coastal place like Walton-on-the-Naze any different?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. Walls facing the sea are normally the first to need attention.
Do you cover smaller places like Walton-on-the-Naze?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can I add another job to the visit?
Yes, we can. Several rooms, windows or areas can go on one quote.
Do you work for letting agents?
Yes. We work for householders, landlords, letting agents, businesses and hotels.
Should I use sand mastic or silicone?
It depends on the window. Period windows in stone or brick normally suit sand mastic and newer frames normally get a flexible sealant.
When will the new mastic be hard?
Not straight away. It skins first and hardens fully later, and we will tell you what to expect.
Should I check with the council before work on a listed or conservation-area home?
It’s best to ask your local planning authority first. Sand mastic is often favoured as like for like but the decision is theirs.
What do you put in the joint?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
How the job changes by surface
Period and listed homes
Many older homes were built with sand mastic round the windows. If your home is listed, ask your local planning authority about consent.
Timber door frames
Doors face weather and wear, so their mastic can fail sooner. We rake it out and renew it.
