Sand mastic near Hurlingham

Windows and doors in Hurlingham

Historic houses like Fulham Palace (about 0.7 miles west) are a reminder that the area around Hurlingham 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. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

Managing a site like Sulivan Primary School? Then the mastic around its windows and doors needs looking after like any other building’s. If you let a flat or house near Imperial Wharf station, cracked sand mastic around sash windows lets in the draughts tenants complain about.

Sand mastic in Hurlingham

Our applicators renew the sand mastic around sash and case windows and doors set in stone or brick. Out comes the old, loose mastic, and new mastic is applied and shaped by hand. We’re often asked to deal with silicone on a period window that looks wrong and draughts and rain around sash boxes, on brick reveals, period & listed homes and tenement windows.

London homes have every kind of window, from timber sashes in period terraces to aluminium and uPVC in newer blocks. The mastic around them dries out and cracks with age, letting in draughts and water.

Big or small, it’s backed by our 12-month guarantee.

What affects the cost of sand mastic

Some jobs are bigger than they look, and some smaller. What affects the quote:

  • Working hours on commercial sites
  • The old material and how stubborn it is
  • How many areas need sealing
  • Any mould that needs treating

Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

What we need to know

When you contact us, it’s useful to know:

  • The address or postcode of the job
  • How we’d reach the joints
  • Any previous sealing or DIY work
  • What the problem is, such as mould, gaps, leaks or cracking

Asking for a quote is easy: tell us what needs doing and where. A few pictures by email make the job easier to understand, and we’ll take it from there.

Work for landlords, hotels and businesses

Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.

Hotels need rooms back in use, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.

DIY sealant or a professional job?

Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.

Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

Different surfaces, different methods

Sash and case windows

The mastic round a sash window is on show so we finish it carefully.

Stone surrounds

Stone surrounds suit sand mastic well. The finish blends with the masonry.

Why it’s worth doing now in Hurlingham

Draughts round a sash window are not always the sashes. Open mastic joints round the box can let air in and new mastic seals them. In London conversions, one flat’s bathroom is often above another flat’s ceiling, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Putting it right early is much less trouble for homes in Hurlingham.

Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.

What you get with us

  • Every job guaranteed for a year
  • Anti-fungal sanitary silicone in wet areas

When to call us in Hurlingham

Decorating can disturb tired mastic. It’s often found when windows are being prepared for paint, which is a good time to renew it.

If you can see any of these, it’s time to have the joints looked at:

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

As a London address, Hurlingham can be tricky for parking: let us know about parking bays, permits or a driveway.

Before you book anyone

  • What the cure time is
  • How much experience the applicator has
  • What happens if the job turns out different
  • Whether they’re fully insured
