Sand mastic for Great Hollands homes and businesses

Sand mastic for homes and businesses in Great Hollands

Burnt sand mastic is a traditional material that sits naturally against stone and brick. It’s a good fit for period properties where a modern sealant bead would stand out. We work on tenement windows, period & listed homes and sash and case windows, and people most often call us about mastic worn away on windows facing the weather and gaps where the frame meets the masonry.

Houses in smaller places like Great Hollands can stand more in the open than those in a built-up town. That’s hard on the mastic around frames and sills.

Great Hollands homes and the weather

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. Bracknell, which Great Hollands is part of, is one of England’s post-war new towns. With many homes from the post-war decades, replacement windows and doors are common. The mastic around replacement frames ages too, and gaps at sills and frame heads are where water gets in.

Homes close to St Michael and St Mary Magdalene's Church include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame. For landlords with property near Bracknell station, older sash windows in a rental need their mastic kept sound to keep the weather out.

Why it’s worth doing now in Great Hollands

New mastic over crumbling mastic will not hold. We remove the loose material first so the new mastic stays put. In an older home around Great Hollands, damp from a failed joint can get into timber and plaster, and that is a much bigger job than renewing the sealant.

Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we’ll go through it with you.

Can I paint the new mastic?

Sand mastic is normally left unpainted, which is what traditional guidance recommends. Ask us before decorating.

What we do, step by step

When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take anything from a few hours to a full day, depending on how many windows. Parking around Great Hollands is usually easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.

  1. First we agree which joints need doing.
  2. Old mastic and any loose material are raked out.
  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. The surface is finished to suit the stone or brick.

Preparing for the visit

  • Tell us about access, such as stairs, a lift or high-level joints
  • On commercial sites, let us know about site rules
  • Let us know about earlier repairs to the joints

Advice

DIY sealant or a professional job?

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.

Do you need sand mastic in Great Hollands?

Most of it is simply age. Even well-laid mastic needs renewing in time, depending on exposure and upkeep.

If you can see any of these, it’s time to have the joints looked at:

  • Mastic that needs renewing before redecorating
  • Old sand mastic that has cracked, crumbled or fallen out
  • Silicone on a period window that looks wrong
  • Gaps where the frame meets the masonry

For site and facilities teams at buildings such as Great Hollands Primary School, larger buildings have plenty of frames, and the mastic around each one ages.
