Sand mastic for Christmas Pie homes and businesses

What we cannot put right

To be straight with you, there are a few things sealant will not fix:

  • Sashes that rattle, stick or will not open
  • Decisions on consent for listed homes
  • Crumbling stone or brickwork round the window

How we handle sand mastic in Christmas Pie

Silicone on a period window often looks wrong and does not suit the building. Sand mastic is the traditional choice and we can swap the silicone for it. We’re often asked to deal with cement or filler used on old window joints that has cracked and old sand mastic that has cracked, crumbled or fallen out, on tenement windows, sash and case windows and stone surrounds.

Homes in small places like Christmas Pie 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.

The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

For landlords and businesses

From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.

We also work for property managers and facilities teams. Several sites can be quoted together, and we’re fully insured for the work.

Surface by surface

Brick reveals

Loose mastic comes out and deep gaps are packed before pointing.

Stone surrounds

Stone surrounds suit sand mastic well. It finishes to look like part of the surround.

What we are called out for in Christmas Pie

Water gets into small cracks in the mastic and loosens it further. Windows facing the weather tend to go first.

The problems people normally mention when they call are:

  • Mastic round period door frames that has failed
  • Silicone on a period window that looks wrong
  • Window mastic to renew ahead of painting
  • Old sand mastic that has cracked, crumbled or fallen out

If you live in an older home near Church of St Bartholomew, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Choosing a sealant specialist

Looking after it afterwards

Once the sealant has cured, a few habits help it last:

  • Make sure water runs off the sill
  • Ask us before painting near the mastic
  • Ask the planning authority about consent for listed or conservation-area homes
  • Don’t run silicone over sand mastic

Avoid sealing over the mastic with silicone. If anything cracks, get it looked at rather than patching it.

Good mastic helps keep the frame dry. Once it fails, water can sit against the timber, which can lead to rot.

Christmas Pie: your questions answered

Do you work for landlords with property near Wanborough station?

Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can ring 0345 464 0079 or send us an email with the details for a clear quote.

Is Christmas Pie in your area for sand mastic?

Yes. Our work covers London and the South East, and Christmas Pie is part of that. Just call 0345 464 0079 or email us with a few details of the job.

Which products do you use?

It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.

Do the sealants smell?

That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.

Do I need permission for sand mastic on a listed building?

It’s best to ask your local planning authority first. Like-for-like sand mastic is often the preferred finish, but they decide.

Which is right for my windows, sand mastic or modern sealant?

That depends on your windows. Period windows in stone or brick normally suit sand mastic and newer frames normally get a flexible sealant.

Is it messy?

Tidy work is part of the job. We protect what’s around the joints, and we clear up when we are done.

Do you do commercial work?

Yes. Commercial and hotel work is a large part of what we do, as well as homes. Working times can be discussed when we quote.

Windows and doors in Christmas Pie

With historic houses such as Wanborough Manor (about 0.6 miles south-east) nearby, there’s older building stock in the area around Christmas Pie 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’s traditional sand mastic. 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.

Rented homes near Wanborough station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about. Schools such as Puttenham CofE Infant School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

What happens on the day

The work is kept neat and contained to the joints we are treating, so you can carry on as normal. Expect the work to take anything from a few hours to a full day, depending on how many windows. Somewhere as small as Christmas Pie, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We look at the surrounds with you and agree the joints to renew.
  2. We remove the old, loose mastic.
  3. We pack any deep voids first.
  4. The sand mastic is mixed and pressed into the joint by hand.
  5. The surface is finished to suit the stone or brick.

Should I try it myself first?

If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.

A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
