The process

When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take anything from a few hours to a full day, depending on how many windows. Somewhere as small as Wadwick, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. First, we look at the surrounds with you and agree what needs doing.
  2. Old, loose mastic is raked out and the joint cleaned.
  3. Large voids are packed out first, so the mastic isn’t too thick.
  4. The mastic is mixed, pressed into the joint by hand and shaped.
  5. We dress the surface so it sits neatly against the masonry.

Preparing for the visit

  • Plan for the work area to be out of bounds to pets and children
  • Tell us about any water getting in
  • Let us know about earlier repairs to the joints

Advice

Sand mastic in Wadwick

Fresh sand mastic forms a skin quite soon but full hardening takes longer. Traditionally, sand mastic is left unpainted, so ask us before you decorate. We’re often asked to deal with mastic dropping out of the joint and gaps where the frame meets the masonry, on stone surrounds, tenement windows and timber door frames.

Outdoor sealant needs dry, clean surfaces, so work on frames around Wadwick is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.

Every job comes with our 12-month guarantee, wherever you are in Hampshire.

How long does the job take?

Most jobs take anything from a few hours to a full day, depending on how many windows, including preparation and clearing up. We’ll confirm how long when we quote.

Can I do it myself?

It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.

Do the sealants smell?

Possibly a little. Any smell clears as the sealant cures.

Do you do commercial work?

Yes. Hotels, offices and other businesses use us, and we are fully insured.

Are you fully insured?

Yes. We are fully insured, and we can confirm the details when we quote.

Can you match the sealant colour?

Normally, yes. Sealants come in white, clear, grey and other colours for many products, and we agree the colour with you before any work starts.

Looking after it afterwards

Simple care keeps the joints in good condition. Our advice:

  • Have rotten timber repaired before new mastic goes in
  • Check the mastic when you check the paintwork
  • Leave the new mastic unpainted
  • Make sure water runs off the sill

When preparing windows for paint, take care around the mastic. Hard scraping can loosen it.

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

What the job involves on each surface

Stone surrounds

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

Period and listed homes

Sand mastic is the like-for-like choice for many period homes. If your home is listed, ask your local planning authority about consent.

Sand mastic in Wadwick: local notes

The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Highclere Castle (about 3.8 miles north) nearby, there’s older building stock in the area around Wadwick as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.

  • Gaps between timber frames and stone or brick
  • Modern sealant on a period surround
  • Wind and rain getting in round a sash window

Rented homes near Whitchurch (Hampshire) station change hands often, and any sash windows need sound mastic to keep draughts and rain out.

Questions to ask before you book

  • What happens if they find a problem under the old sealant
  • Whether VAT is included
  • Which sealant they’ll use, and why
  • Who does the work, and how experienced they are

Choosing a sealant specialist

DIY sealant or a professional job?

Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.

What happens if it’s left?

Before painting the windows, it pays to renew the mastic. Painting over failed mastic does not seal it and traditional guidance is to leave the new mastic unpainted. Older cottages and farmhouses around Wadwick can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
