Sand mastic for homes and businesses in Lamb Corner

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. We are often asked to deal with tired mastic found when preparing windows for paint and mastic dropping out of the joint, across period & listed homes, timber door frames and stone surrounds.

Homes in small places like Lamb Corner 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.

Our work is backed for twelve months, in Lamb Corner and everywhere else we cover.

Questions from Lamb Corner

Do you cover smaller places like Lamb Corner?

Yes, Lamb Corner is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.

Do you work for landlords with property near Manningtree station?

Yes. We work for landlords and agents as well as householders. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear quote.

Will the old sealant be removed?

Yes, always, and completely. New silicone does not stick to old silicone, so the joint is cleaned back first.

How long will you be here?

Typically it takes anything from a few hours to a full day, depending on how many windows. Bigger jobs take longer, and we will say how long yours will take.

Is there any odour?

Some sealants have a smell while they cure. Ventilation helps.

Can new sealant go over the old?

No. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.

Do you work for hotels and businesses?

Yes. Commercial and hotel work is a large part of what we do, as well as homes. Working times can be discussed when we quote.

When will the new mastic be hard?

It forms a skin fairly soon, then hardens over a longer period. The weather and joint depth both affect it.

What the job involves on each surface

Brick reveals

We rake out the old mastic and pack deep voids before pointing.

Tenement and terrace windows

Upper-floor windows need access planning. Tell us the height and we will confirm what’s needed.

When to call us in Lamb Corner

Over the years, sand mastic weathers. It hardens, cracks and starts to come away from the frame or the masonry.

The most common problems we see are:

  • Mastic round period door frames that has failed
  • Mastic that needs renewing before redecorating
  • A silicone bead on a sash window that spoils the look
  • Weathered mastic on the most exposed windows

For site and facilities teams at buildings such as Dedham Church of England Voluntary Controlled Primary School, its window and door frames need their mastic kept sound, just like a home’s.

Questions to ask before you book

  • Whether they’re fully insured

Our hiring checklist

What sand mastic looks like in Lamb Corner

Historic houses like Castle House (about 0.9 miles east) are a reminder that the area around Lamb Corner has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. 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.

Rented homes near Manningtree station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about. For an older house near a landmark such as Parish Church of St Mary, the joint between an old wall and a newer frame is normally the first place rain gets in.

How the visit works

At the end, we look at the finished work together and explain the cure time. The work normally takes a few hours for a single window, longer for several, depending on how much there is to do. In a small place like Lamb Corner, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We check the window surrounds and agree which joints need renewing.
  2. Old, loose mastic is raked out and the joint cleaned.
  3. We pack any deep gaps so the mastic sits at the right depth.
  4. The mastic is mixed, pressed into the joint by hand and shaped.
  5. We dress the surface so it sits neatly against the masonry.

Before we arrive

  • Let us know about parking restrictions
  • Let us know about earlier repairs to the joints
  • Try not to wet indoor joints just before the visit

Related advice

Can I do it myself?

The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.

Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

For landlords and businesses

Housing providers, facilities teams and property managers book us too. We can quote a run of properties together, and we’re fully insured for the work.

From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.

What happens if it’s left?

An open joint round the frame lets weather in. Left, water can reach the timber and the wall so renewing it early protects the window. In a small place like Lamb Corner, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

A failed joint rarely gets cheaper to fix by waiting. If you are unsure, call 0345 464 0079 or drop us an email for an honest opinion and a quote.

Why us?

  • Any old sealant cut out fully, not covered over
  • A 12-month guarantee on all work
  • We are fully insured
  • Sanitary silicone with an anti-fungal additive in wet areas

Take a look at our cost guide or customer reviews.

Looking after it afterwards

Joint life depends on how it’s used and looked after. We suggest:

  • Do not paint over the new mastic
  • Avoid patching sand mastic with silicone
  • Make sure water runs off the sill
  • Find out about consent before window work on a listed home

Avoid painting over the new mastic, which is the traditional advice. If you are redecorating, ask us first.

Once mastic starts to crumble, rain gets in. That water can reach the timber frame and the wall, so renewing it early is worth it.
