What happens on the day

There isn’t 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 for a single window, longer for several from start to finish. For a village or hamlet like Upper Farringdon, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.

  1. We check each window surround and the condition of the joint.
  2. The joint is raked out and cleaned.
  3. We fill deep gaps so the new mastic isn’t too thick.
  4. We point the joint with sand mastic by hand.
  5. We finish the mastic to a tidy line.

Before we arrive

  • Mention if the joints have been sealed before
  • Plan for the work area to be out of bounds to pets and children
  • Let us know about parking restrictions

About our sand mastic in Upper Farringdon

Sand mastic does not last for ever and gaps open up round the frame. Renewing it closes the gap so the surround looks right again. We work on brick reveals, period & listed homes and sash and case windows, and common reasons people get in touch are gaps between timber frames and stone or brick and draughty sash windows at the surround.

In a village or hamlet like Upper Farringdon, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.

You are covered for a year from the day we finish. If anything isn’t right with it, ring 0345 464 0079 or drop us an email.

What we can’t put right

To be straight with you, some problems need a different trade:

  • Sashes that need overhauling
  • Crumbling stone or brickwork round the window
  • Planning or listed building consent (your local planning authority decides)

If in doubt, call 0345 464 0079 or email us and we’ll say what we think before booking.

What the job involves on each surface

Brick reveals

Sand mastic is also used where timber frames meet brick. It gives a traditional finish.

Timber door frames

A neat sand mastic joint round a front door suits a period home.

DIY sealant or a professional job?

A careful DIYer can reseal a simple joint, 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.

Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.

Upper Farringdon homes and the weather

London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Bentworth Hall (about 3.9 miles north-west) nearby, there’s older building stock in the area around Upper Farringdon as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.

For an older house near a landmark such as Church of All Saints, frames set in older brick or stone need a sealant that suits the wall as well as the frame. If you let a flat or house near Alton station, any sash windows need sound mastic to keep draughts and rain out.

Why it’s worth doing now in Upper Farringdon

Replacing sash windows is a big decision for a period home, and in listed buildings it may need consent. Where the frames are in good order, new mastic seals the surround. In a small place like Upper Farringdon, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

What you pay reflects the work, not guesswork. That is why we ask a few questions first and give you a clear price before any work starts.

What you get with us

  • Neat joints and a tidy finish
  • ARBOMaster approved applicator

Can sand mastic be painted?

Traditional guidance is not to paint over sand mastic. If you’re redecorating the window, ask us first and we will advise.

Do I need to be at home?

That depends on where the joints are. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.

Can you match the sealant colour?

Most of the time, yes. We will tell you which colours the right product comes in and agree one before any work starts.

What do you need from me for a quote?

Where the job is, what the problem is and roughly how big it is. Photos by email help too.

Can you quote for more than one area?

Of course. Doing several areas at once is normally more efficient.

What sealant do you use?

The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.

What affects the cost of sand mastic

We quote each job individually. These are the things that affect it:

  • Any working-time requirements on site
  • Which sealant suits the joint
  • How many areas need sealing
  • The old material and how stubborn it is

Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.

What we need to know

What to tell us when you ask for a quote:

  • How many joints, rooms or windows are involved
  • Whether it’s a home or a business
  • Access, such as stairs, a lift or height
  • Where the job is, and your postcode

Quotes start with a quick conversation. Describe the problem, the location and the size of the job. When it suits you, ring 0345 464 0079 or send us an email.
