Sand mastic in Golden Pot

How we handle sand mastic in Golden Pot

Sand mastic has long been used to fill the joint between timber frames and masonry. It’s a mix of sand and a linseed-oil-based binder, applied by hand. On period homes, it looks right where silicone wouldn’t. If you have failed mastic on an exposed elevation and draughty sash windows at the surround, we can help.

Somewhere as small as Golden Pot, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.

You are covered for a year from the day we finish. If there’s a problem with it, please ring 0345 464 0079 or email us.

What happens if it’s left?

New mastic over crumbling mastic won’t hold. We remove the loose material first so the new mastic stays put. Where a wall is exposed, as many are in small places like Golden Pot, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

Doing several joints on one visit is generally more efficient than separate visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.

Looking after it afterwards

How long the joints last depends on use and care. We suggest:

  • Sort the mastic before the decorators arrive
  • Avoid heavy scraping on the mastic joint
  • Have rotten timber repaired before new mastic goes in
  • Leave the new mastic unpainted

Keep gutters and sills clear so water runs away from the surround. Constant wetting wears the mastic faster.

Fine cracks show the mastic is starting to fail. It’s easier to renew it before it drops out.

How the job changes by surface

Brick reveals

An open joint at a brick reveal lets weather in. Renewing the mastic closes it.

Tenement and terrace windows

Tenements and terraces often have many sash windows with ageing mastic. We can do one window or several.

Landlord and commercial work in Golden Pot

Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.

Letting agents often deal with us directly. Tell us the address, the job and how access works.

Should I try it myself first?

What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.

Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

Windows and doors in Golden Pot

The South East is one of the drier parts 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 Hall Place (about 3.5 miles south-west) nearby, there’s older building stock in the area around Golden Pot as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.

Hall Place, about 3.5 miles south-west, is one of the historic houses in the wider area around Golden Pot, and older homes nearby need a sealant that suits their walls. Letting a property close to Alton station? Then older sash windows in a rental need their mastic kept sound to keep the weather out.

What happens on the day

There’s no need to move everything out, only the area right around the joints. Everything nearby is protected, and the work takes a few hours per window, depending on the condition of the joints for a typical job. In a small place like Golden Pot, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. Each surround is checked first.
  2. We rake out the old mastic and clean the joint.
  3. Large voids are packed out.
  4. New sand mastic is applied and shaped by hand.
  5. The finish is dressed neatly.

How to prepare

  • Let us know about parking restrictions
  • Mention if the joints have been sealed before
  • Move anything stored near the joints

  • How many rooms, windows or areas are involved
  • Access and height
  • The type of sealant required

  • A few pictures by email, if you can

Golden Pot questions

Is Golden Pot within the area you cover?

Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.

Can you help a landlord with a rental near Alton station?

Yes, we work for landlords and letting agents. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear quote.

Do you hold any approvals?

Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.

Is it worth trying it myself?

Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.

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

Yes, it’s a common request. All the old silicone is removed first so the mastic can sit properly.

Do you remove the old sealant?

Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.

Do I have to be there?

For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.

Can I paint the new mastic?

The usual advice is to leave sand mastic unpainted. Ask us before you decorate around it and we will advise.
