Trusted sand mastic in Lower Horsebridge

Can I do it myself?

Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.

How we handle sand mastic in Lower Horsebridge

Burnt sand mastic is a traditional material blends with stone and brick surrounds. It suits period and listed homes where a modern sealant bead would stand out. Common call-outs are for draughty sash windows at the surround and old cement repairs round a window that have failed, on brick reveals, period & listed homes and sash and case windows.

Homes in small places like Lower Horsebridge often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.

All our work is covered by a 12-month guarantee.

How to look after the new joints

So the new joints stay in good condition:

  • Renew mastic before redecorating the windows
  • Inspect the joints round the windows every year or so
  • Get any rot dealt with first
  • Avoid patching sand mastic with silicone

Check the mastic when you check the paintwork. Small cracks are easier to deal with early.

Good mastic helps keep the frame dry. Failed mastic lets water reach the timber and timber that stays wet can rot.

What happens on the day

Every visit runs the same way: we check the joints, protect the area around them, carry out the job and clear up. Most jobs take a few hours for a single window, longer for several. For a village or hamlet like Lower Horsebridge, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.

  1. First we agree which joints need doing.
  2. We remove the old, loose mastic.
  3. Deep gaps are packed so the mastic sits at the right depth.
  4. The sand mastic is mixed and pressed into the joint by hand.
  5. We dress the finish so it sits neatly against the masonry.

Preparing for the visit

  • Try not to wet indoor joints just before the visit
  • Clear the area around the work
  • Let us know about parking restrictions

Advice

Different surfaces, different methods

Sash and case windows

A sash window’s box frame sits in the masonry opening. Sand mastic seals the joint round it.

Timber door frames

Sand mastic is used round timber door frames too. The method is the same as for windows.

Landlords, agents and businesses in Lower Horsebridge

For anyone letting property in or around Lower Horsebridge, jobs at different addresses can go on one quote. Just tell us the addresses and what each one needs, and photos by email help.

Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. Several properties can be quoted together.

Do you need sand mastic in Lower Horsebridge?

Scraping and sanding before painting can loosen old mastic. It’s often found when windows are being prepared for paint, which is a good time to renew it.

Any of these means the joints need attention:

  • Cement or filler used on old window joints that has cracked
  • Old sand mastic that has cracked, crumbled or fallen out
  • Draughts and rain around sash boxes
  • Failed mastic on an exposed elevation

If you let a flat or house near Polegate station, cracked sand mastic around sash windows lets in the draughts tenants complain about.

Before you book anyone

  • What guarantee comes with the work

What affects the cost of sand mastic

For a quick quote, just ask. The main things that affect it are:

  • Whether the work is at height
  • The type of sealant required
  • The number and length of the joints
  • Working hours on commercial sites

Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

Asking for a quote

Photos by email are helpful but not essential. Please mention:

  • Access, such as stairs, a lift or height
  • Any previous sealing or DIY work
  • Photos by email, if that’s easy
  • What’s wrong with the joints now

Asking for a quote is easy: let us know what needs doing and where. A few pictures by email make the job easier to understand, and we will come back to you with a quote.

Frames and glazing around Lower Horsebridge

Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Horselunges Manor (about 0.6 miles north-east) are a reminder that the area around Lower Horsebridge 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.

For site and facilities teams at buildings such as Hellingly Community Primary School, the mastic around its windows and doors needs looking after like any other building’s. If you live in an older home near Zoar Strict Baptist Chapel, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
