Trusted sand mastic in Rockbourne

Sand mastic in Rockbourne

Silicone on a period window often looks wrong and doesn’t suit the building. Sand mastic is the traditional choice, and we can replace one with the other. If you’re dealing with mastic worn away on windows facing the weather and patchy fillers round a sash window, we can help.

In a village or hamlet like Rockbourne, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.

We stand behind the work with a one-year guarantee, so you are not left on your own once the job is done.

Do you need sand mastic in Rockbourne?

Most of it is simply age. Sand mastic is a maintenance item like any pointing, depending on exposure and upkeep.

The most common problems we see are:

  • Failed mastic on an exposed elevation
  • Patchy fillers round a sash window
  • Silicone on a period window that looks wrong
  • Old sand mastic that has cracked, crumbled or fallen out

If you look after a building such as Western Downland Church of England Aided Primary School, its window and door frames need their mastic kept sound, just like a home’s.

Do you guarantee sand mastic work?

Should I check with the council before work on a listed or conservation-area home?

Speak to your local planning authority before work starts. Sand mastic is often favoured as like for like but the decision is theirs.

Should I try DIY first?

That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.

Do I need to be at home?

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

What happens on the day

You don’t need to clear the whole room or building before we come, just the space around the work. Everything nearby is protected, and the work takes a few hours for a single window, longer for several for a typical job. Somewhere like Rockbourne needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.

  1. Each surround is checked first.
  2. The joint is raked out and cleaned.
  3. Large voids are packed out.
  4. New sand mastic is applied and shaped by hand.
  5. We finish the mastic to a tidy line.

Before we arrive

  • Keep children and pets away from the work area
  • Mention if the joints have been sealed before
  • On commercial sites, let us know about site rules

Advice

Why deal with it now?

Not every filler suits an old window surround. Sand mastic matches what was there, which can matter on listed and conservation-area homes. In a small place like Rockbourne, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we’ll go through it with you.

What you get with us

  • Any old sealant cut out fully, not covered over
  • 20+ years of sealant experience
  • A 12-month guarantee on all work
  • Anti-fungal sanitary silicone in wet areas

What sand mastic looks like in Rockbourne

With historic houses such as Breamore House (about 2.4 miles east) nearby, there’s older building stock in the area around Rockbourne 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. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

In the older streets around Church of St Andrew, the joint between an old wall and a newer frame is normally the first place rain gets in.

What sealant work cannot fix

To be straight with you, there are a few things sealant will not fix:

  • Masonry that needs repairing
  • Whether work needs listed building consent
  • Sashes that rattle, stick or won’t open

If you are not sure, just call 0345 464 0079 or drop us an email and we will give you a straight answer before you book.

Where we work in Rockbourne

  • Stone surrounds
  • Tenement windows
  • Brick reveals
  • Sash and case windows
  • Period & listed homes
  • Timber door frames

Looking after it afterwards

How long the joints last depends on use and care. Here’s what we suggest:

  • Have rotten timber repaired before new mastic goes in
  • Go gently near the mastic when preparing windows
  • Keep sills and gutters clear so water drains away
  • Renew mastic before redecorating the windows

Do not touch or press the mastic while it hardens. It forms a skin fairly soon, but takes longer to harden fully.

Crumbling mastic lets rain into the joint. It can soak into the frame and the surrounding masonry so early renewal protects both.

What affects the quote in Rockbourne

You’ll get a clear quote before we start. It’s based on:

  • How many areas need sealing
  • Any working-time requirements on site
  • How much old sealant there is and how hard it is to remove
  • Access and height

No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.

What to tell us for a quote

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

  • The rough size of the job
  • Pictures of the joints, sent by email
  • If it’s domestic, commercial or a hotel
  • Where the job is, and your postcode
