Your questions about sand mastic in Broadwater Down

Do you cover Broadwater Down for sand mastic?

Yes. We work across London and the South East, and Broadwater Down is part of that. Just phone 0345 464 0079 or email us with a few details of the job.

Do you work for landlords with property near Tunbridge Wells station?

Yes, we work for landlords and letting agents. You can phone 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before we start.

Is it possible to take out silicone and use sand mastic instead?

Generally, yes. With the silicone removed and the joint cleaned, sand mastic is applied by hand.

Will the old sealant be removed?

Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.

Where do you work from?

We’re based in Crawley, and we work across South East England, London and Scotland.

Do I need to be at home?

It depends on the job. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.

How much does sand mastic cost in Broadwater Down?

It depends on the job, so we quote each one individually. To get one, ring 0345 464 0079 or send us an email and let us know what needs doing and where.

Can I do it myself?

Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.

Sand mastic for homes and businesses in Broadwater Down

Silicone on a period window often looks wrong and is not always the right material. Sand mastic gives a finish that matches the age of the house, and we can replace one with the other. If you have draughts and rain around sash boxes and gaps round a timber door in stone or brick, we can help, on brick reveals, period & listed homes and stone surrounds alike.

Around Broadwater Down, conservatories, garden rooms and patio doors are often part of the house. Their glazing joints and frame seals are as much a part of the job as the windows.

A 12-month guarantee comes as standard.

Keeping the joints in good condition

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

  • Plan mastic work ahead of painting
  • Avoid heavy scraping on the mastic joint
  • Check with your local planning authority if your home is listed
  • Make sure water runs off the sill

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

An open joint round the box lets weather through. The longer it’s left, the more the joint opens as more mastic falls out.

How we quote for sand mastic

The quote reflects the job in front of us. We take into account:

  • Whether there’s mould to deal with
  • How easy the joints are to reach
  • Working hours on commercial sites
  • The type of sealant required

We don’t show prices on the website, because each job is priced on what it involves. For a quick quote, please call 0345 464 0079 or send us an email.

When to call us in Broadwater Down

Over the years, sand mastic weathers. It hardens, cracks and starts to come away on the stone or timber.

Keep an eye out for these signs:

  • A silicone bead on a sash window that spoils the look
  • Draughts and rain around sash boxes
  • Weathered mastic on the most exposed windows
  • Gaps where the frame meets the masonry

In the older streets around St Mark's Church, the joint between an old wall and a newer frame is generally the first place rain gets in.

Our hiring checklist

How it works

There’s no need to move everything out, just the space around the work. We protect the rest, and the work takes a few hours per window, depending on the condition of the joints in most cases. Parking around Broadwater Down is normally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.

  1. First we agree which joints need doing.
  2. We remove the old, loose mastic.
  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. We dress the finish so it sits neatly against the masonry.

Before we arrive

  • Let us know about stairs, lifts or work at height
  • Mention any leaks or damp you’ve noticed
  • Tell us if parking is tricky

Advice

Can I do it myself?

The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.

Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Broadwater Down homes and the weather

Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Groombridge Place (about 2.7 miles west) are a reminder that the area around Broadwater Down has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.

Letting a property close to Tunbridge Wells station? Then older sash windows in a rental need their mastic kept sound to keep the weather out. Schools such as Broadwater Down Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.
