What affects the quote in Berrick Salome

Every job gets its own quote. These are the things that affect it:

  • Any mould that needs treating
  • The number of rooms or windows
  • The type of sealant required
  • Whether the work is at height

Combining jobs into one visit generally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.

What to tell us for a quote

Before you ask for a quote, have a think about:

  • Where the property is
  • The problem you’ve noticed
  • If it’s domestic, commercial or a hotel
  • How we’d reach the joints

Call for a quick quote, or send an email if you’d rather. Tell us about the joints that need doing and we will explain what’s involved and give you a clear quote.

How we handle sand mastic in Berrick Salome

If your home is listed or in a conservation area, check with your local planning authority whether consent is needed for work to windows. Sand mastic is often favoured as a like-for-like material. We work on timber door frames, sash and case windows and stone surrounds, and people most often call us about silicone on a period window that looks wrong and gaps between timber frames and stone or brick.

Somewhere as small as Berrick Salome, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.

The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or send us an email.

What we do, step by step

There’s no need to move everything out, just the space around the work. We protect the rest, and the job takes a few hours for a single window, longer for several in most cases. For a village or hamlet like Berrick Salome, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.

  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 isn’t too thick.
  4. We mix the sand mastic and apply it by hand, shaping it to the joint.
  5. We dress the surface so it sits neatly against the masonry.

How to prepare

  • For indoor joints, keep the area dry beforehand if you can
  • Tell us about any water getting in
  • Tell us about access, such as stairs, a lift or high-level joints

Different surfaces, different methods

Sash and case windows

The mastic round a sash window is on show, so a neat, even finish matters.

Timber door frames

Door frames get knocked and soaked and the mastic can crack early. We rake it out and renew it.

What we’re called out for in Berrick Salome

Shallow joints are a common cause. Mastic that’s too thin cracks and drops out, which is why we pack deep voids first and get the depth right.

People generally contact us after spotting something like this:

  • Wind and rain getting in round a sash window
  • Gaps where the frame meets the masonry
  • Old cement repairs round a window that have failed
  • Gaps round a timber door in stone or brick

Around Berrick Salome, as everywhere, sand mastic is only as good as the preparation behind it.

I rent my home. Can I book you?

Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we will tell you what we are using.

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

What sand mastic looks like in Berrick Salome

London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Brightwell Manor (about 3.5 miles south-west) are a reminder that the area around Berrick Salome has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.

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

Can I do it myself?

Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.

Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
