  • Cement or filler used on old window joints that has cracked
  • Open joints round the window box

For landlords with property near Buxted station, cracked sand mastic around sash windows lets in the draughts tenants complain about.

Choosing a sealant specialist

How we handle sand mastic in Waldron

On many period windows, sand mastic looks right and suits the building. Newer frames usually get a flexible sealant instead, and we will talk through which suits your home. If you’re dealing with gaps where the frame meets the masonry and cracked mastic round a front door frame, we can put it right.

Homes in small places like Waldron often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.

All our work is covered by our one-year guarantee, wherever you are in East Sussex.

What sand mastic looks like in Waldron

Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

Homes close to The Parish Church of All Saints include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

How to look after the new joints

So the new joints stay in good condition:

  • Ask a joiner to look at soft timber first
  • Inspect the joints round the windows every year or so
  • Leave the new mastic unpainted
  • Clear gutters so water doesn’t pour onto the windows

Make sure water drains away from the window surround. Constant wetting wears the mastic faster.

Once mastic starts to crumble, rain gets in. It can soak into the frame and the surrounding masonry, so renewing it early is worth it.

Questions from Waldron

Is Waldron within the area you cover?

Yes, Waldron is covered. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.

Is Waldron in your area for sand mastic?

Yes, Waldron is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or drop us an email with a few details of the job, and we’ll send you a clear quote.

Can you quote for more than one area?

Yes, and it often makes sense. Combining jobs makes good use of the visit.

What guarantee comes with the work?

Our one-year guarantee covers every job.

Should I use sand mastic or silicone?

For period timber windows in stone or brick, sand mastic is often the better fit. Modern frames normally suit a flexible sealant, and we’ll explain why.

Which products do you use?

We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we will tell you what we’re using.

I rent my home. Can I book you?

Yes, but check with your landlord or agent first. Landlords are often happy for the work to be arranged.

Can I choose the sealant colour?

Usually, yes. White, clear and grey are common, and other colours are available for many products, and we agree the colour with you before work begins.

Honest limits

A few problems are outside what sealant work can do:

  • Timber that has rotted
  • Masonry that needs repairing
  • Putty and glazing repairs

Not sure which it is? You can phone 0345 464 0079 or drop us an email and we will tell you honestly.

Where we work in Waldron

  • Sash and case windows
  • Tenement windows
  • Period & listed homes

What affects the cost of sand mastic

There’s no set price list. What we look at:

  • Working hours on commercial sites
  • The old material and how stubborn it is
  • Which sealant suits the joint
  • How easy the joints are to reach

A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re unsure, phone 0345 464 0079 or drop us an email for an honest opinion and a quote.

Helping us quote

What to tell us when you ask for a quote:

  • Roughly how big the job is
  • A few pictures by email, if you can
  • What’s wrong with the joints now
  • Whether it’s a home or a business

The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints.

The process

The work is kept neat and contained to the area we’re working on. The job normally takes anything from a few hours to a full day, depending on how many windows, and we tell you how long to leave it before we go. Somewhere like Waldron 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. First we agree which joints need doing.
  2. We remove the old, loose mastic.
  3. Deep gaps are packed so the mastic sits at the right depth.
  4. We apply the mastic by hand and shape it.
  5. The surface is finished to suit the stone or brick.

Preparing for the visit

  • For business premises, tell us about site rules or sign-in
  • Mention any tricky access
  • Let us know if you’ve seen damp or leaks

Work for landlords, hotels and businesses

In hotels, rooms out of use cost money, so the work can be planned room by room. We have worked in hotels as well as homes and businesses.

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.

What the job involves on each surface

Stone surrounds

Old stone surrounds are often uneven, so the gap is not the same all the way round. We shape it by hand to follow the stone.

Timber door frames

Door frames get knocked and soaked, so their mastic can fail sooner. It’s renewed by hand.
