Sand mastic near Westmeston

FAQs for Westmeston

Do you work for landlords with property near Hassocks station?

Yes, we work for landlords and letting agents. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before we start.

Will you come out to Westmeston?

Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.

Do you hold any approvals?

Yes. We’re approved under the ARBOMaster scheme.

Is there any odour?

There can be a smell while the sealant cures, but it fades. Ventilation helps.

Can I paint the new mastic?

The usual advice is to leave sand mastic unpainted. Ask us before you decorate around it and we will talk you through it.

Will the old sealant be removed?

Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.

Do you work for hotels and businesses?

Yes. We work in offices, washrooms, hotels and other commercial premises. Working times can be discussed when we quote.

Where is Mr Mastic based?

Our base is in Crawley, and we cover South East England, London and all of Scotland.

Sand mastic for homes and businesses in Westmeston

Silicone on a period window often looks wrong and is not always the right material. Sand mastic gives a finish that matches the age of the house, and we can replace one with the other. We work on tenement windows, brick reveals and period & listed homes, and common reasons people get in touch are modern sealant on a period surround and open joints round the window box.

In a village or hamlet like Westmeston, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these don’t always suit modern silicone, and sometimes a traditional sand mastic is the better choice.

DIY sealant or a professional job?

If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.

Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

What sand mastic looks like in Westmeston

Historic houses like Preston Manor & Gardens (about 4.9 miles south-west) are a reminder that the area around Westmeston has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

Managing a site like Ditchling (St Margaret's) Church of England Primary School? Then the mastic around its windows and doors needs looking after like any other building’s. Homes close to The Parish Church of St Martin include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

How to choose a mastic man

Work for landlords, hotels and businesses

We work for landlords and agents as well as homeowners. Resealing between tenancies keeps a property looking cared for.

We also work for property managers and facilities teams. We can quote a run of properties together, and we are fully insured for the work.

How the visit works

We keep the work tidy and contained to the joints we’re treating. Expect the work to take a few hours per window, depending on the condition of the joints, and we explain the cure time before we leave. Somewhere like Westmeston needs a little journey planning: 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.

  1. We check each window surround and the condition of the joint.
  2. We rake out the old mastic and clean the joint.
  3. We fill deep gaps so the new mastic isn’t too thick.
  4. New sand mastic is applied and shaped by hand.
  5. We finish the mastic to a tidy line.

How to prepare

  • Mention any parking rules near the property
  • Tell us about access, such as stairs, a lift or high-level joints
  • Keep children and pets away from the work area

On a listed home or in a conservation area, the right material matters. Like-for-like sand mastic is normally favoured.

Brick reveals

An open joint at a brick reveal lets weather in. Renewing the mastic closes it.
