About our sand mastic in East Stourmouth

Across East Stourmouth, we renew sand mastic around sash and case windows. Each joint is raked out, prepared and pointed by hand for a neat, traditional finish. We work on stone surrounds, period & listed homes and sash and case windows, and people most often call us about gaps round a timber door in stone or brick and silicone on a period window that looks wrong.

In a village or hamlet like East Stourmouth, 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.

We guarantee the work for a year. If something is not right with it in that time, tell us and we will put it right.

Surface by surface

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.

Period and listed homes

A traditional finish suits a period property, and sand mastic is one of them.

Why it’s worth doing now in East Stourmouth

Silicone might seem the quicker option, but on period stone or brick it often looks out of place. Sand mastic suits the building and blends with the stone or brick. Where a wall is exposed, as many are in small places like East Stourmouth, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.

What you get with us

  • 12-month guarantee on every job
  • Neat joints and a tidy finish
  • We never seal over old sealant
  • ARBOMaster approved applicator

How the visit works

A visit follows a simple pattern: we look at the joints together, protect the area around them, carry out the job and clear up. Most jobs take anything from a few hours to a full day, depending on how many windows. For a village or hamlet like East Stourmouth, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided 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 is not too thick.
  4. We point the joint with sand mastic by hand.
  5. The finish is dressed neatly.

Preparing for the visit

  • Tell us about access, such as stairs, a lift or high-level joints
  • Clear items away from the joints we are working on
  • On commercial sites, let us know about site rules

Ask for a quote

Asking for a quote is easy: tell us what needs doing and where and its rough size. Photos by email help us understand the job, and we’ll take it from there.

Advice

How to look after the new joints

Good habits help new joints last longer. Our tips:

  • Sort the mastic before the decorators arrive
  • Ask the planning authority about consent for listed or conservation-area homes
  • Get any rot dealt with first
  • Keep modern sealant off the mastic

Do not run silicone over the new mastic. If anything cracks, get it looked at rather than patching it.

Gaps round a sash box let in draughts and rain. Left, the gap tends to get bigger as more mastic falls out.

What affects the quote in East Stourmouth

We quote each job individually. This is what makes a difference:

  • When we can work, for business premises
  • The amount of work
  • Whether there’s mould to deal with
  • The product the joint needs

The cost reflects the work involved, not guesswork. That’s why we ask a few questions first.

What to tell us for a quote

When you call or email, these details help:

  • The problem you’ve noticed
  • A few pictures by email, if you can
  • Whether it has been sealed before
  • Access, such as stairs, a lift or height

If you’re in East Stourmouth and need sand mastic, ring 0345 464 0079 or send us an email. Tell us what the problem is and where, and you will get a clear quote before work begins.

What we are called out for in East Stourmouth

Paint, silicone or cement used over old mastic causes problems. They don’t suit the joint, and they generally need raking out.

Any of these means the joints need attention:

  • Gaps between timber frames and stone or brick
  • Draughty sash windows at the surround
  • Patchy fillers round a sash window
  • Mastic worn away on windows facing the weather

If you live in an older home near All Saints Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Questions to ask before you book

  • How long the guarantee is
  • How the colour is chosen
  • How the joint is cleaned and prepared
  • Which sealant they’ll use, and why

Where is Mr Mastic based?

We are a Crawley-based firm, with over 20 years’ experience. Our area covers South East England, London and Scotland.

Should I try it myself first?

Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.

A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.

What sand mastic looks like in East Stourmouth

London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Quex Park (about 4.7 miles north-east) nearby, there’s older building stock in the area around East Stourmouth as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.

Letting a property close to Minster station? Then older sash windows in a rental need their mastic kept sound to keep the weather out.
