Sand mastic for Lymore homes and businesses

How we handle sand mastic in Lymore

Our applicators renew the sand mastic around sash and case windows and doors set in stone or brick. Out comes the old, loose mastic, the joint is prepared and new mastic is shaped by hand. Typical jobs include old cement repairs round a window that have failed and silicone on a period window that looks wrong, across period & listed homes, timber door frames and sash and case windows.

Around Lymore, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.

A 12-month guarantee comes as standard.

When to call us in Lymore

Sand mastic slowly weathers. It hardens, cracks and starts to come away on the stone or timber.

Signs it’s time to call us include:

  • Failed mastic on an exposed elevation
  • Silicone on a period window that looks wrong
  • Old cement repairs round a window that have failed
  • Mastic dropping out of the joint

For an older house near a landmark such as Church of All Saints, the joint between an old wall and a newer frame is usually the first place rain gets in.

Questions to ask before you book

  • Whether the sealant suits the joint
  • How long to leave it before use
  • Who does the work, and how experienced they are
  • What happens if they find a problem under the old sealant

10 questions to ask before booking

DIY versus a professional finish

A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

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

What happens if it’s left?

Not every draught comes from the sashes themselves. Gaps between the frame and the wall can be just as bad, and renewing the mastic closes them. In a small place like Lymore, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.

Why us?

  • Homes, businesses and hotels
  • Tidy, careful work

Frames and glazing around Lymore

Lymore is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on the mastic around older windows and doors, especially on the side facing the sea. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

Schools such as Milford-on-Sea Church of England Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s. If you let a flat or house near Lymington Town station, older sash windows in a rental need their mastic kept sound to keep the weather out.

Common questions in Lymore

Is sand mastic in a coastal place like Lymore any different?

Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. Walls facing the sea are usually the first to need attention.

Is Lymore within the area you cover?

Yes, Lymore is covered. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.

Will you leave a mess?

Tidy work is part of the job. We protect what’s around the joints, and we clear up when we are done.

What guarantee comes with the work?

Our one-year guarantee covers every job, sand mastic included.

Can I add another job to the visit?

Yes. Just list everything you need and we will quote it together.

Which products do you use?

Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.

What exactly is sand mastic?

It’s the traditional filler for the joint round timber windows and doors. It combines sand with a linseed-oil-based binder.

Do the sealants smell?

It depends on the product. Some smell for a while, some hardly at all.

Looking after it afterwards

After the cure time, these simple habits help:

  • Keep modern sealant off the mastic
  • Leave the new mastic unpainted
  • Take care around the mastic when scraping paint
  • Have rotten timber repaired before new mastic goes in

Avoid sealing over the mastic with silicone. If anything cracks, get it looked at before trying a quick fix.

It’s best to renew mastic before painting the windows. Painting over failed mastic hides the problem for a while.

What we do, step by step

On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The work itself takes a few hours for a single window, longer for several. For a village or hamlet like Lymore, 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. We look at the surrounds with you and agree the joints to renew.
  2. Old mastic and any loose material are raked out.
  3. Deep gaps are packed so the mastic sits at the right depth.
  4. We apply the mastic by hand and shape it.
  5. We dress the finish so it sits neatly against the masonry.

Before we arrive

  • Clear items away from the joints we are working on
  • Let us know about parking restrictions
  • Mention any sign-in or site rules at work premises
