Why it’s worth doing now in Hurstbourne Priors

A silicone bead can be quicker, but on period stone or brick it often looks out of place. Sand mastic is the traditional material and finishes neatly against the masonry. Older cottages and farmhouses around Hurstbourne Priors can have timber 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 play a part.

Why us?

  • Neat joints and a tidy finish
  • Anti-fungal sanitary silicone in wet areas
  • An ARBOMaster approved applicator
  • We’re fully insured

How the job changes by surface

Brick reveals

Gaps between frame and brick let in rain and draughts. Renewing the mastic closes it.

Stone surrounds

Stone openings are rarely perfectly straight, so the joint varies in width. We shape it by hand to follow the stone.

How to look after the new joints

After the cure time, these simple habits help:

  • Get any rot dealt with first
  • Make sure water runs off the sill
  • Sort the mastic before the decorators arrive
  • Avoid heavy scraping on the mastic joint

Avoid sealing over the mastic with silicone. If you see a crack, ask us to take a look rather than patching it.

Fine cracks show the mastic is starting to fail. It’s easier to renew it before it drops out.

How we quote for sand mastic

We do not publish a price list, because jobs vary so much. The quote depends on:

  • The number and length of the joints
  • Any working-time requirements on site
  • The number of rooms or windows
  • Mould in or behind the old joints

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

Asking for a quote

To help us quote quickly, please include:

  • Where the job is, and your postcode

  • If someone has resealed it before

The process

There’s no need to move everything out, only the area right around the joints. Everything nearby is protected, and the job takes a few hours per window, depending on the condition of the joints for a typical job. In a small place like Hurstbourne Priors, access is normally 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. We rake out the old mastic and clean the joint.
  3. Large voids are packed out first, so the mastic is not too thick.
  4. Sand mastic is mixed and applied by hand, then shaped to the joint.
  5. The mastic is finished to sit tidily against the stone or brick.

Preparing for the visit

  • Move anything stored near the joints
  • Keep children and pets away from the work area
  • Mention any sign-in or site rules at work premises

DIY versus a professional finish

Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
