Sand mastic near Wrotham Heath

Frames and glazing around Wrotham Heath

Historic houses like Old Soar Manor (about 2.7 miles south-west) are a reminder that the area around Wrotham Heath 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, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

For landlords with property near Borough Green & Wrotham station, any sash windows need sound mastic to keep draughts and rain out. For an older house near a landmark such as Church of St Margaret, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

How we handle sand mastic in Wrotham Heath

Traditional burnt sand mastic blends with stone and brick surrounds. It’s a good fit for period properties where a modern sealant bead would stand out. We work on timber door frames, sash and case windows and tenement windows, and the jobs we see most are mastic round period door frames that has failed and gaps where the frame meets the masonry.

Somewhere as small as Wrotham Heath, 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.

All of our work is guaranteed for twelve months, in Wrotham Heath and everywhere else we cover.

What we do, step by step

You don’t need to clear the whole room or building, just the space around the work. Everything nearby is protected, and the job takes a few hours per window, depending on the condition of the joints for a typical job. For a village or hamlet like Wrotham Heath, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.

  1. First, we look at the surrounds with you and agree what needs doing.
  2. We rake out the old mastic and clean the joint.
  3. We pack any deep gaps so the mastic sits at the right depth.
  4. Sand mastic is mixed and applied by hand, then shaped to the joint.
  5. The finish is dressed so it sits neatly against the stone or brick.

Getting ready for the visit

  • For business premises, tell us about site rules or sign-in

Advice

Quotes for sand mastic in Wrotham Heath

Jobs vary more than people expect. The main factors:

  • The number of rooms or windows
  • The number and length of the joints
  • Any working-time requirements on site
  • How much old sealant there is and how hard it is to remove

There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote.

What to tell us for a quote

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

  • If someone has resealed it before
  • A few photos by email, if you can
  • The rough size of the job
  • Access, such as stairs, a lift or height

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

What we cannot put right

New sealant cannot fix everything, and we’ll tell you before work begins. Sealant won’t put right:

  • Whether work needs listed building consent
  • Cracked or broken glass
  • Masonry that needs repairing

If in doubt, phone 0345 464 0079 or send us an email and we’ll say what we think.

Signs you need sand mastic in Wrotham Heath

Most of it is simply age. Even well-laid mastic needs renewing in time and how long it lasts depends on the weather it faces.

Look out for any of the following:

  • Draughty sash windows at the surround
  • Gaps where the frame meets the masonry
  • Patchy fillers round a sash window
  • Cracked mastic round a front door frame

If you look after a building such as Platt Church of England Voluntary Aided Primary School, the mastic around its windows and doors needs looking after like any other building’s.

How to choose a mastic man

For landlords and businesses

Housing providers, facilities teams and property managers book us too. We can quote a run of properties together, and we are fully insured.

In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.

What the job involves on each surface

Period and listed homes

A traditional finish suits a period property.

Tenement and terrace windows

Tenements and terraces often have many sash windows with ageing mastic. We work on single windows or whole elevations.

Why it’s worth doing now in Wrotham Heath

New mastic over crumbling mastic will not hold. We remove the loose material first so the new work lasts. Around Wrotham Heath, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

Combining jobs into one visit normally makes better use of the time than several visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.
