Sand mastic for Wooburn homes and businesses

What the job involves on each surface

Timber door frames

Sand mastic is used round timber door frames too. We renew it the same way as on windows.

Stone surrounds

Sand mastic sits naturally against stone. It finishes to look like part of the surround.

How we handle sand mastic in Wooburn

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 swap the silicone for it. If you’re dealing with cracked mastic round a front door frame and tired mastic found when preparing windows for paint, we can help.

In a village or hamlet like Wooburn, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these don’t always suit modern silicone, and sometimes a traditional sand mastic is the better choice.

A 12-month guarantee comes as standard.

What we are called out for in Wooburn

Paint, silicone or cement used over old mastic causes problems. They don’t suit the joint, and they usually need raking out.

Keep an eye out for these signs:

  • Modern sealant on a period surround
  • Crumbling sand mastic round a window
  • Mastic worn away on windows facing the weather
  • Cement or filler used on old window joints that has cracked

Managing a site like St Paul's Church of England Combined School? Then larger buildings have plenty of frames, and the mastic around each one ages.

  • How the joint is cleaned and prepared
  • What product goes in the joint
  • Is VAT in the price?

Our hiring checklist

Frames and glazing around Wooburn

Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Cliveden (about 1.5 miles south) are a reminder that the area around Wooburn 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.

If you live in an older home near Church of St Paul, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Rented homes near Bourne End station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about.

The process

Most of a good job is in the preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. In total, it normally takes anything from a few hours to a full day, depending on how many windows. For a village or hamlet like Wooburn, the journey is planned in advance: 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. We start by checking each surround and agreeing the joints to renew.
  2. The loose and crumbling mastic is raked out and the joint cleaned.
  3. Deep voids are packed so the mastic is the right thickness.
  4. Sand mastic is mixed and applied by hand, then shaped to the joint.
  5. We dress the surface so it sits neatly against the masonry.

Preparing for the visit

  • Let us know about earlier repairs to the joints
  • For indoor joints, keep the area dry beforehand if you can
  • Let us know about parking restrictions

Landlord and commercial work in Wooburn

For anyone letting property in or around Wooburn, several properties can go on one quote. Send us the addresses and the work at each, and photos by email help.

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.

Looking after it afterwards

Once the sealant has cured, a few habits help it last:

  • Renew mastic before redecorating the windows
  • Take care around the mastic when scraping paint
  • Do not paint over the new mastic
  • Don’t run silicone over sand mastic

Don’t touch or press the mastic while it hardens. It forms a skin fairly soon but needs longer to fully harden.

Crumbling mastic lets rain into the joint. That water can reach the timber frame and the wall so early renewal protects both.

Quotes for sand mastic in Wooburn

Call for a quick quote. The main things that affect it are:

  • The size of the job
  • How much old sealant there is and how hard it is to remove
  • Any mould that needs treating
  • Working hours on commercial sites

Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you are not sure whether it needs doing, phone 0345 464 0079 or send us an email for an honest opinion and a quote.

What to tell us for a quote

There’s no need for technical detail. It helps if you can tell us:

  • Access, such as stairs, a lift or height
  • The problem you’ve noticed
  • Roughly how big the job is
  • If someone has resealed it before

Getting a quote is simple: let us know what needs doing and where, and roughly how big it is. A few photos by email make the job easier to understand, and we’ll take it from there.

Why act early in Wooburn

Before painting the windows, it pays to renew the mastic. Painting over failed mastic does not seal it, and the new mastic is traditionally left unpainted. Around Wooburn, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first.
