Leave it or put it right?

New sash windows are a major, costly change, and in listed buildings it may need consent. Where the frames are in good order, new mastic seals the surround. Older cottages and farmhouses around Lower Brailes can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

What it costs depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before work begins, so you know where you stand.

How we handle sand mastic in Lower Brailes

For a listed home or one in a conservation area, ask your local planning authority whether consent is needed for work to windows. Like-for-like sand mastic is often the preferred finish. If you have wind and rain getting in round a sash window and gaps between timber frames and stone or brick, we can help, whatever the surface.

Homes in small places like Lower Brailes 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 a one-year guarantee, wherever you are in Oxfordshire.

Lower Brailes questions

Do you cover smaller places like Lower Brailes?

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

Do you cover Lower Brailes for sand mastic?

Yes. We work across London and the South East, and Lower Brailes is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job.

Do the sealants smell?

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

Can you seal over the old sealant?

No. New silicone won’t bond to old silicone, and anything trapped underneath, including mould and water, stays there. It all has to come out first.

Do you do commercial work?

Yes. We can plan bigger jobs in stages to suit the site.

Will you leave a mess?

No. The area is protected while we work and cleaned up afterwards.

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.

Do you work for letting agents?

Yes, we do. We work in homes, commercial premises and hotels.

What sand mastic looks like in Lower Brailes

Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

Homes close to Church of St George include some older properties, and the joint between an old wall and a newer frame is normally the first place rain gets in.

What we do, step by step

On the day, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before work begins. The work usually takes a few hours for a single window, longer for several. Somewhere as small as Lower Brailes, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. First, we look at the surrounds with you and agree what needs doing.
  2. Old, loose mastic is raked out and the joint cleaned.
  3. Large voids are packed out first, so the mastic is not too thick.
  4. We mix the sand mastic and apply it by hand, shaping it to the joint.
  5. The mastic is finished to sit tidily against the stone or brick.

What we’re called out for in Lower Brailes

Most of it is simply age. Sand mastic is a maintenance item like any pointing, depending on exposure and upkeep.

The most common problems we see are:

  • Draughts and rain around sash boxes
  • Gaps round a timber door in stone or brick
  • Gaps between timber frames and stone or brick
  • Silicone on a period window that looks wrong

If you look after a building such as Brailes CofE Primary School, the mastic around its windows and doors needs looking after like any other building’s.

Different surfaces, different methods

Tenement and terrace windows

Rows of sash windows on tenements and terraces often need renewing together. We can do one window or several.

Brick reveals

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

What we can’t put right

Honest advice matters more to us than a booking, so here’s what sealant cannot fix:

  • Broken panes
  • Sashes that need overhauling
  • Timber that has rotted

If in doubt, call 0345 464 0079 or email us and we will say what we think before you book.

Surfaces we seal

  • Tenement windows
  • Stone surrounds
  • Timber door frames
  • Sash and case windows
  • Brick reveals
  • Period & listed homes

DIY versus a professional finish

A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
