Sand mastic in New Street

For landlords and businesses

Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can be quoted together.

Hotels need rooms back in use, so the work can be planned room by room. We’ve worked in hotels as well as homes and businesses.

About our sand mastic in New Street

Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s made from sand and a linseed-oil-based binder, applied by hand. On period homes, it looks right where silicone wouldn’t. If you have gaps where the frame meets the masonry and wind and rain getting in round a sash window, we can help, on timber door frames, stone surrounds and brick reveals alike.

Mastic can only go onto a dry, clean joint, so window work in New Street is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.

A one-year guarantee comes with the work, just as it does everywhere we cover.

What sealant work can’t fix

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

  • Masonry that needs repairing
  • Whether work needs listed building consent
  • Sash cords, weights and draught-proofing of the sashes

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

What we seal

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

What we’re called out for in New Street

Rain on the window surround works into any crack and loosens it further. Exposed elevations normally fail first.

It’s worth asking for a quote if you see:

  • Wind and rain getting in round a sash window
  • Mastic round period door frames that has failed
  • Weathered mastic on the most exposed windows
  • Gaps where the frame meets the masonry

For site and facilities teams at buildings such as Culverstone Green Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

What to look for in a quote

  • Whether you can choose the colour
  • The length of the guarantee
  • Is the old sealant removed completely?
  • How the surfaces are prepared before sealing

Choosing a sealant specialist

Can I do it myself?

Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

New Street homes and the weather

Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Cobham College (about 3.6 miles north-east) are a reminder that the area around New Street has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.

Rented homes near Meopham station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out. In the older streets around Church of Saint Peter, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Why it’s worth doing now in New Street

Not every filler suits an old window surround. Sand mastic matches what was there, which can matter on listed and conservation-area homes. Around New Street, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part.

How the job changes by surface

Timber door frames

Period doors in stone or brick openings are often pointed with sand mastic. The method is the same as for windows.

Brick reveals

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

How the visit works

Good joint work is mostly preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it normally takes a few hours for a single window, longer for several. Somewhere like New Street needs a little journey planning: 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. Each surround is checked first.
  2. We rake out the old mastic and clean the joint.
  3. We fill deep gaps so the new mastic is not too thick.
  4. We point the joint with sand mastic by hand.
  5. The finish is dressed neatly.

How to prepare

  • Keep children and pets away from the work area
  • Let us know about stairs, lifts or work at height
  • Move anything stored near the joints

How to get a quote
