Sand mastic near Waterend

Work for landlords, hotels 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.

Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. We can quote for more than one property at once.

Sand mastic in Waterend

Old sand mastic cracks, crumbles and falls out over time, leaving gaps round the window. We rake it out and renew it so the surround looks right again. We work on timber door frames, period & listed homes and tenement windows, and people most often call us about wind and rain getting in round a sash window and old cement repairs round a window that have failed.

In a village or hamlet like Waterend, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these don’t always suit modern silicone, and sometimes a traditional sand mastic is the better choice.

Each job carries a 12-month guarantee, large or small.

Why it’s worth doing now in Waterend

Before painting the windows, it pays to renew the mastic. Paint over cracked mastic will not stop the gaps and traditional guidance is to leave the new mastic unpainted. In a small place like Waterend, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

We don’t show prices on the website, because each job is priced on what it involves. For a quick quote, please phone 0345 464 0079 or send us an email and we will talk you through it.

Frames and glazing around Waterend

Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like West Wycombe Park House (about 3.1 miles east) are a reminder that the area around Waterend has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.

For site and facilities teams at buildings such as Radnage Church of England Primary School, larger buildings have plenty of frames, and the mastic around each one ages. In the older streets around Church of St Mary, the joint between an old wall and a newer frame is generally the first place rain gets in.

How the job changes by surface

Timber door frames

Period doors in stone or brick openings are often pointed with sand mastic. The method is the same as for windows.

Sash and case windows

Most of our sand mastic work is on sash windows. Each joint round the box is raked out and renewed.

Honest limits

In fairness, some problems need a different trade:

  • Planning or listed building consent (your local planning authority decides)
  • Timber that has rotted
  • Sashes that rattle, stick or won’t open

If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think before booking.

Waterend questions

Can you do sand mastic in Waterend?

Yes. We work across London and the South East, and Waterend is part of that. You can call 0345 464 0079 or drop us an email and let us know what needs doing.

I let a flat near Saunderton station. Can you help?

Yes, we work for letting agents and landlords. Just ring 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear quote.

Is consent needed for window work on a listed home?

Your local planning authority is the one to ask. They’ll tell you if consent is needed for work to your windows.

Can you match the sealant colour?

We’ll suggest a colour to suit the surroundings. The product needed can limit the range.

Can old silicone round a sash window be swapped for sand mastic?

Generally, yes. Once the silicone is out and the joint prepared, sand mastic is applied by hand.

What information do you need?

The location, the problem and the rough size of the job. If you can, email a few photos.

Are you an approved applicator?

Yes. We hold ARBOMaster approved applicator status and we’re fully insured too.

Is it OK to seal over old sealant?

No. Fresh sealant doesn’t stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.

When to call us in Waterend

Rain on the window surround works into any crack and loosens it further. Windows facing the weather tend to go first.

People generally contact us when they notice one of these:

  • Silicone on a period window that looks wrong
  • Draughts and rain around sash boxes
  • Mastic round period door frames that has failed
  • Weathered mastic on the most exposed windows

If you let a flat or house near Saunderton station, any sash windows need sound mastic to keep draughts and rain out.

Before booking anyone

  • Whether they seal over old material or remove it
  • How much experience the applicator has
  • What guarantee comes with the work
  • Whether the sealant suits the joint

What we do, step by step

There is not much for you to do on the day. Show us the job and we’ll take it from there. The job generally takes a few hours per window, depending on the condition of the joints.

  1. We check each window surround and the condition of the joint.
  2. The joint is raked out and cleaned.
  3. Large voids are packed out.
  4. New sand mastic is applied and shaped by hand.
  5. The finish is dressed neatly.

Getting ready for the visit

How to look after the new joints

Joint life depends on how it’s used and looked after. Here’s what we suggest:

  • Keep sills and gutters clear so water drains away
  • Renew mastic before redecorating the windows
  • Take care around the mastic when scraping paint
  • Get any rot dealt with first

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

An open joint round the box lets weather through. The longer it’s left, the more the joint opens.
