How we handle sand mastic in East Molesey

On many period windows, sand mastic looks right and suits the building. On modern frames we’d normally use a flexible sealant, and we’ll talk through which suits your home. We work on stone surrounds, brick reveals and tenement windows, and the jobs we see most are gaps round a timber door in stone or brick and gaps where the frame meets the masonry.

In a smaller place like East Molesey, some walls face open ground and catch the full force of the weather. The mastic around frames on those walls tends to age faster.

There’s a 12-month guarantee on every job.

Sand mastic in East Molesey: local notes

Historic houses like Hampton Court Palace (about 0.7 miles east) are a reminder that the area around East Molesey 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’s traditional sand mastic. 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.

In the older streets around Church of St Mary, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Managing a site like The Orchard Infant School? Then larger buildings have plenty of frames, and the mastic around each one ages.

What affects the quote in East Molesey

The quote reflects the job in front of us. We look at:

  • How many areas need sealing
  • When we can work, for business premises
  • Whether there’s mould to deal with
  • How much old sealant there is and how hard it is to remove

Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we will explain what it covers.

Asking for a quote

The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:

  • The problem you’ve noticed
  • The address or postcode of the job
  • How we’d reach the joints
  • Any previous sealing or DIY work

The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and email photos if that’s easy.

How it works

We keep the work tidy and contained to the area we’re working on. Expect the work to take anything from a few hours to a full day, depending on how many windows, and we tell you how long to leave it before we go. In a smaller place like East Molesey, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.

  1. We check the window surrounds and agree which joints need renewing.
  2. The loose and crumbling mastic is raked out and the joint cleaned.
  3. Large voids are packed out first, so the mastic isn’t too thick.
  4. Sand mastic is mixed and applied by hand, then shaped to the joint.
  5. The mastic is finished to sit tidily against the stone or brick.

Before we arrive

  • Mention any leaks or damp you’ve noticed
  • Mention any sign-in or site rules at work premises
  • Mention any parking rules near the property

Advice

Common problems we fix in East Molesey

Decorating can disturb tired mastic. Many people find it crumbling when they prepare the windows.

Look out for any of the following:

  • Mastic that needs renewing before redecorating
  • Modern sealant on a period surround
  • Mastic dropping out of the joint
  • Mastic worn away on windows facing the weather

Rented homes near Hampton Court station change hands often, and any sash windows need sound mastic to keep draughts and rain out.

Before booking anyone

  • What happens if the job turns out different
  • How the colour is chosen
  • What product goes in the joint

FAQs for East Molesey

Is East Molesey within the area you cover?

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

Do you cover East Molesey for sand mastic?

Yes. Our work covers London and the South East, and East Molesey is part of that. You can call 0345 464 0079 or email us and tell us what needs doing.

What’s sand mastic made of?

Sand plus a binder based on linseed oil. It’s applied by hand and shaped to suit the surround.

Can landlords and businesses book you?

Yes, we do. We work in homes, commercial premises and hotels, and we’re fully insured.

Can you work on commercial sites?

Yes, regularly. Larger jobs can be planned room by room or area by area.

Can new sealant go over the old?

No, and we never do. It may look fine at first, but the new layer lifts away from the old one. The old sealant has to come out completely.

Can you replace silicone on a period window with sand mastic?

Yes. The silicone is cut out and the joint cleaned, then point it with sand mastic.

Can I do it myself?

You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.

Aftercare tips

A little care helps the new joints last. We recommend:

  • Keep modern sealant off the mastic
  • Find out about consent before window work on a listed home
  • Look over the window mastic once a year
  • Clear gutters so water doesn’t pour onto the windows

Look at the mastic when you look over the windows. Catching cracks early keeps repairs small.

Good mastic helps keep the frame dry. Once it fails, water can sit against the timber and timber that stays wet can rot.

Should I try it myself first?

Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

A DIY attempt does not rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
