How we quote for sand mastic

We quote each job individually. This is what makes a difference:

  • Whether the work is at height
  • The number of rooms or windows
  • Whether there’s mould to deal with
  • Whether old sealant or filler has to be cut out

Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we’ll explain what it covers.

What to tell us for a quote

A few details help us give you an accurate quote. When you get in contact, it helps to mention:

  • Roughly how big the job is
  • Photos by email, if that is easy
  • Whether it’s a home or a business
  • Where the property is

We don’t publish a price list, as no two jobs are quite the same. Instead, we send you a clear quote for your job. To arrange one, ring 0345 464 0079 or send us an email.

Sand mastic in Chiddingly

A silicone bead around a sash window can look out of place and isn’t always the right material. Sand mastic is the traditional choice, and we can replace one with the other. We work on period & listed homes, stone surrounds and timber door frames, and the jobs we see most are gaps where the frame meets the masonry and crumbling sand mastic round a window.

Somewhere as small as Chiddingly, older homes often have timber frames set in stone or brickwork. Older buildings like these don’t always suit modern silicone, and sometimes a traditional sand mastic is the better choice.

We guarantee the work for a year. If something is not right with it in that time, tell us and we will put it right.

Leave it or put it right?

Draughts round a sash window aren’t always the sashes. Open mastic joints round the box can let air in and new mastic seals them. Older cottages and farmhouses around Chiddingly can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

Combining jobs into one visit normally makes better use of the time than several visits. You will get one clear quote for the whole job.

DIY sealant or a professional job?

What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.

A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.

Your questions about sand mastic in Chiddingly

Will you come out to Chiddingly?

Yes. Chiddingly is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

I let a flat near Berwick (Sussex) station. Can you help?

Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can call 0345 464 0079 or drop us an email with the details for a clear quote.

Does someone need to be in?

For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.

Can you work on commercial sites?

Yes. Hotels, offices and other businesses use us and we are fully insured.

How much does sand mastic cost in Chiddingly?

We don’t publish prices, because the cost depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.

Is it messy?

Tidy work is part of the job. Nearby surfaces are protected, and the area is left clean when we finish.

Can you quote for more than one area?

Of course. Doing several areas at once is usually more efficient, so mention them when you ask for a quote.

What information do you need?

Only a few details: the address or postcode, what’s wrong and any access issues. Then ring 0345 464 0079 or send us an email.

Keeping the joints in good condition

Looking after new joints is easy:

  • Ask the planning authority about consent for listed or conservation-area homes
  • Inspect the joints round the windows every year or so
  • Ask a joiner to look at soft timber first
  • Keep modern sealant off the mastic

Avoid sealing over the mastic with silicone. If anything cracks, get it looked at before trying a quick fix.

Small cracks are a sign the mastic is ageing. Renewing it then is simpler than waiting until it falls out.

For landlords and businesses

Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.

Hotels need rooms back in use, so the work can be planned room by room. We’ve worked in hotels as well as homes and businesses.

When to call us in Chiddingly

Decorating can disturb tired mastic. It’s often found when windows are being prepared for paint.

Common reasons people contact us are:

  • Old sand mastic that has cracked, crumbled or fallen out
  • Mastic round period door frames that has failed
  • Weathered mastic on the most exposed windows
  • Tired mastic found when preparing windows for paint

If you look after a building such as Chiddingly Primary School, its window and door frames need their mastic kept sound, just like a home’s.

Questions to ask before you book

  • How long the guarantee is
  • Whether you can choose the colour
  • Whether the sealant suits the joint
  • What happens if the job turns out different

Our hiring checklist

What sand mastic looks like in Chiddingly

With historic houses such as Horselunges Manor (about 2.7 miles south-east) nearby, there’s older building stock in the area around Chiddingly as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

For landlords with property near Berwick (Sussex) station, older sash windows in a rental need their mastic kept sound to keep the weather out. In the older streets around The Parish Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

What happens on the day

At the end, we look at the finished work together. The visit itself generally takes a few hours for a single window, longer for several, depending on how much there is to do. In a small place like Chiddingly, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We start by checking each surround and agreeing the joints to renew.
  2. Old, loose mastic is raked out and the joint cleaned.
  3. Deep voids are packed so the mastic is the right thickness.
  4. The mastic is mixed, pressed into the joint by hand and shaped.
  5. We dress the surface so it sits neatly against the masonry.

Before we arrive

  • Tell us about access, such as stairs, a lift or high-level joints
  • Mention any sign-in or site rules at work premises
  • Keep pets and children clear of the area while we work
