Sand mastic near Ashurst Bridge

Sand mastic in Ashurst Bridge

If your home is listed or in a conservation area, check with your local planning authority if consent is needed before window work. Like-for-like sand mastic is often the preferred finish. We work on period & listed homes, tenement windows and sash and case windows, and the jobs we see most are cracked mastic round a front door frame and old cement repairs round a window that have failed.

Around Ashurst Bridge, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.

The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we’ll put it right.

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 call for the right materials, safe access and experience.

If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.

Common problems we fix in Ashurst Bridge

Shallow joints are a common cause. Mastic that’s too thin cracks and drops out so we make sure the new mastic is the right thickness.

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

  • Modern sealant on a period surround
  • Window mastic to renew ahead of painting
  • Cracked mastic round a front door frame
  • Crumbling sand mastic round a window

Schools such as Hazel Wood Infant School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

10 questions to ask before you book

Looking after it afterwards

No joint lasts for ever, but care makes a real difference. A few tips:

  • Inspect the joints round the windows every year or so
  • Take care around the mastic when scraping paint
  • Leave the new mastic unpainted
  • Get any rot dealt with first

Check the mastic when you check the paintwork. Catching cracks early keeps repairs small.

Crumbling mastic lets rain into the joint. It can soak into the frame and the surrounding masonry, so renewing it early is worth it.

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 per window, depending on the condition of the joints, depending on the size of the job. For a village or hamlet like Ashurst Bridge, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.

  1. First we agree which joints need doing.
  2. We remove the old, loose mastic.
  3. We pack any deep voids first.
  4. The sand mastic is mixed and pressed into the joint by hand.
  5. We dress the finish so it sits neatly against the masonry.

Getting ready for the visit

  • Let us know about stairs, lifts or work at height
  • Let us know if you’ve seen damp or leaks
  • Tell us about any previous sealing or DIY attempts

Ashurst Bridge homes and the weather

Ashurst Bridge is within about 3 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. With historic houses such as Southampton Tudor House and Garden (about 4.8 miles east) nearby, there’s older building stock in the area around Ashurst Bridge as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.

For landlords with property near Totton station, cracked sand mastic around sash windows lets in the draughts tenants complain about. For an older house near a landmark such as Church of St Matthew, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Landlords, agents and businesses in Ashurst Bridge

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.

We regularly work with letting and managing agents. Tell us the address, the job and how access works.

Leave it or put it right?

Not every draught comes from the sashes themselves. Gaps between the frame and the wall can be just as bad and new mastic seals them. Where a wall is exposed, as many are in small places like Ashurst Bridge, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.

What you get with us

  • A 12-month guarantee on all work
  • Anti-fungal sanitary silicone in wet areas
  • Arbo and Everbuild products
  • More than 20 years in sealant work

What exactly is sand mastic?

It’s sand mixed with a linseed-oil-based binder for the joint between timber frames and masonry.

How long will you be here?

That depends on how much there is to do, but as a guide it takes a few hours per window, depending on the condition of the joints. We’ll give you a better idea when we quote.
