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.

A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

Sand mastic for homes and businesses in Finkley Down

We work across Finkley Down renewing sand mastic on sash windows and doors. Each joint is raked out, prepared and pointed by hand for a neat, traditional finish. If you’re dealing with crumbling sand mastic round a window and gaps where the frame meets the masonry, we can put it right, on brick reveals, period & listed homes and stone surrounds alike.

Homes in small places like Finkley Down 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.

All of our work is guaranteed for twelve months, in Finkley Down and everywhere else we cover.

Windows and doors in Finkley Down

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.

Schools such as Vigo Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. Rented homes near Andover station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about.

Different surfaces, different methods

Stone surrounds

Stone surrounds suit sand mastic well. The finish blends with the masonry.

Timber door frames

Period doors in stone or brick openings are often pointed with sand mastic. We renew it the same way as on windows.

Keeping the joints in good condition

Aftercare is simple, and it makes a real difference:

  • Avoid heavy scraping on the mastic joint
  • Avoid patching sand mastic with silicone
  • Check with your local planning authority if your home is listed
  • Do not paint over the new mastic

Keep paint scrapers and sanders off the mastic when redecorating. Hard scraping can loosen it.

Sound mastic protects the frame. Failed mastic lets water reach the timber, which can lead to rot.

What we do, step by step

There’s no need to move everything out before we come, only the area right around the joints. We protect the rest, and the work takes a few hours for a single window, longer for several for a typical job. In a small place like Finkley Down, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. Each surround is checked first.
  2. We rake out the old mastic and clean the joint.
  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.

How to prepare

  • Mention if the joints have been sealed before
  • On commercial sites, let us know about site rules
  • Clear items away from the joints we’re working on

Advice

Why deal with it now?

Gaps round a sash window let in rain and draughts. Water can get to the frame and the masonry so renewing it early protects the window. In a small place like Finkley Down, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote and we’ll talk you through it.

Work for landlords, hotels and businesses

In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.

A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
