Sand mastic in Crouch

Crouch homes and the weather

Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Belmont House and Gardens (about 4.2 miles west) nearby, there’s older building stock in the area around Crouch as well as newer homes. 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.

Schools such as Boughton-under-Blean and Dunkirk Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. Homes close to Church of St Peter and St Paul include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Sand mastic in Crouch, done properly

For a listed home or one in a conservation area, ask your local planning authority if consent is needed before window work. Like-for-like sand mastic is often the preferred finish. Typical jobs include mastic round period door frames that has failed and mastic worn away on windows facing the weather, across brick reveals, period & listed homes and stone surrounds.

Somewhere as small as Crouch, 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.

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

Signs you need sand mastic in Crouch

Paint, silicone or cement used over old mastic causes problems. They do not suit the joint, and they usually need raking out.

The problems people generally mention when they call are:

  • Mastic that needs renewing before redecorating
  • Failed mastic on an exposed elevation
  • Gaps where the frame meets the masonry
  • Wind and rain getting in round a sash window

Rented homes near Selling station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out.

How to choose a mastic man

Why it’s worth doing now in Crouch

Gaps round a sash window let in rain and draughts. Left, water can reach the timber and the wall so renewing it early protects the window. In a small place like Crouch, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

Doing several joints on one visit usually 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.

DIY versus a professional finish

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.

Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Surface by surface

Sash and case windows

Most of our sand mastic work is on sash windows. We renew the mastic round each box.

Timber door frames

Round a period front door, sand mastic gives the right look.

Aftercare tips

Simple care keeps the joints in good condition. We recommend:

  • Ask us before painting near the mastic
  • Sort the mastic before the decorators arrive
  • Have rotten timber repaired before new mastic goes in
  • Ask the planning authority about consent for listed or conservation-area homes

Make sure water drains away from the window surround. Constant wetting wears the mastic faster.

Sound mastic protects the frame. Once it fails, water can sit against the timber and timber that stays wet can rot.

The process

On the day, we start by going over the job with you, so there are no surprises. Surfaces next to the work are protected before any work begins. The work generally takes anything from a few hours to a full day, depending on how many windows. In a small place like Crouch, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. First we agree which joints need doing.
  2. Old mastic and any loose material are raked out.
  3. We pack any deep voids first.
  4. We apply the mastic by hand and shape it.
  5. The surface is finished to suit the stone or brick.

Preparing for the visit

  • Mention any tricky access
  • Let us know about parking restrictions
  • Mention if the joints have been sealed before
