Sand mastic in Bierton

Sand mastic in Bierton

Sand mastic suits most period window surrounds. On modern frames we’d normally use a flexible sealant and we’ll explain which is best for yours. We’re often asked to deal with cement or filler used on old window joints that has cracked and modern sealant on a period surround, across sash and case windows, brick reveals and timber door frames.

Homes in small places like Bierton often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.

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

Leave it or put it right?

If you’re redecorating, renew the mastic first. Paint over cracked mastic will not stop the gaps and traditional guidance is to leave the new mastic unpainted. Around Bierton, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.

Frames and glazing around Bierton

Rainfall in the South East is lower than in much 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 James, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Managing a site like Bierton Church of England Combined School? Then its window and door frames need their mastic kept sound, just like a home’s.

Can I do it myself?

Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.

When it is not the sealant

A few problems are outside what sealant work can do:

  • Planning or listed building consent (your local planning authority decides)
  • Cracked or broken glass
  • Crumbling stone or brickwork round the window

If in doubt, call 0345 464 0079 or send us an email and we will say what we think.

Yes. Bierton is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

How long does sand mastic take to go off?

The surface skins quite quickly, then hardens over a longer period. The weather and joint depth both affect it.

When to call us in Bierton

Some old mastic was never deep enough. Mastic that is too thin cracks and drops out so we make sure the new mastic is the right thickness.

The most common problems we see are:

  • Open joints round the window box
  • Failed mastic on an exposed elevation
  • Cracked mastic round a front door frame
  • Wind and rain getting in round a sash window

Rented homes near Aylesbury station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about.

Before you book anyone

  • What happens if they find a problem under the old sealant
  • When the joint can take water or movement
  • Whether they’re fully insured
  • Whether all the old sealant comes out first

How to choose a mastic man

Work for landlords, hotels and businesses

Landlords and letting agents in Bierton can book us as well as householders. Resealing between tenancies is a simple way to keep a property in good order.

Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.

How it works

On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The work itself takes a few hours for a single window, longer for several from start to finish. In a small place like Bierton, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We check the window surrounds and agree which joints need renewing.
  2. Old, loose mastic is raked out and the joint cleaned.
  3. Large voids are packed out first, so the mastic is not too thick.
  4. We mix the sand mastic and apply it by hand, shaping it to the joint.
  5. The mastic is finished to sit tidily against the stone or brick.

Getting ready for the visit

  • Try not to wet indoor joints just before the visit
  • Let us know about stairs, lifts or work at height
  • On commercial sites, let us know about site rules
