Sand mastic in Rookley Green

How to look after the new joints

How long the joints last depends on use and care. We suggest:

  • Don’t paint over the new mastic
  • Do not run silicone over sand mastic
  • Check the mastic when you check the paintwork
  • Go gently near the mastic when preparing windows

Check the mastic when you check the paintwork. Catching cracks early keeps repairs small.

Gaps round a sash box let in draughts and rain. The longer it’s left, the more the joint opens.

Sand mastic in Rookley Green

On many period windows, sand mastic looks right and suits the building. Newer frames generally get a flexible sealant instead, and we will talk through which suits your home. Common call-outs are for a silicone bead on a sash window that spoils the look and cement or filler used on old window joints that has cracked, on stone surrounds, brick reveals and period & listed homes.

Around Rookley Green, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.

Each job carries a 12-month guarantee.

Your questions about sand mastic in Rookley Green

Do you work for landlords with property near Shanklin station?

Yes, landlords and agents are among the people we work for. Just phone 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear price.

Will you come out to Rookley Green?

Yes. Rookley Green is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.

Should I check with the council before work on a listed or conservation-area home?

Checking first is sensible. Your local planning authority can say if consent is needed for work on a listed home or in a conservation area.

Is it possible to take out silicone and use sand mastic instead?

Yes. The silicone is cut out and the joint cleaned before the sand mastic goes in.

Which is right for my windows, sand mastic or modern sealant?

We’ll talk it through with you. Period homes often look best with sand mastic and newer frames suit modern sealant.

What do you need from me for a quote?

Let us know what needs doing and where, plus pictures if you have them. We’ll ask anything else we need to know.

Do you remove the old sealant?

Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.

Common problems we fix in Rookley Green

Age is the main cause. Sand mastic is a maintenance item like any pointing and how long it lasts depends on the weather it faces.

Keep an eye out for these signs:

  • Cement or filler used on old window joints that has cracked
  • A silicone bead on a sash window that spoils the look
  • Wind and rain getting in round a sash window
  • Gaps where the frame meets the masonry

With historic houses such as Sheat Manor (about 1.1 miles north-west) nearby, there’s older building stock in the area around Rookley Green as well as newer homes.

DIY sealant or a professional job?

Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.

Work for landlords, hotels and businesses

Housing providers, facilities teams and property managers book us too. Several sites can be quoted together, and we’re fully insured for the work.

Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.

What happens on the day

The work is kept neat and contained to the area we are working on. The job normally takes anything from a few hours to a full day, depending on how many windows, and we tell you how long to leave it before we go. Somewhere as small as Rookley Green, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We check each window surround and the condition of the joint.
  2. We rake out the old mastic and clean the joint.
  3. We fill deep gaps so the new mastic isn’t too thick.
  4. We point the joint with sand mastic by hand.
  5. The finish is dressed neatly.

Getting ready for the visit

  • Mention any sign-in or site rules at work premises
  • Mention any tricky access
  • Plan for the work area to be out of bounds to pets and children

What happens if it’s left?

If you are redecorating, renew the mastic first. Paint over cracked mastic will not stop the gaps, and the new mastic is traditionally left unpainted. Where a wall is exposed, as many are in small places like Rookley Green, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
