Trusted sand mastic in Ebernoe

Looking after it afterwards

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

  • Plan mastic work ahead of painting
  • Ask the planning authority about consent for listed or conservation-area homes
  • Take care around the mastic when scraping paint
  • Check the mastic when you check the paintwork

Keep paint scrapers and sanders off the mastic when redecorating. It can be damaged by heavy scraping.

An open joint round the box lets weather through. Left, the gap tends to get bigger.

Sand mastic in Ebernoe, done properly

Old sand mastic cracks, crumbles and falls out over time and gaps open up round the frame. We rake it out and renew it and tidies the surround. If you are dealing with open joints round the window box and old cement repairs round a window that have failed, we can put it right, on tenement windows, brick reveals and sash and case windows alike.

Homes in small places like Ebernoe often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.

The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

Your questions about sand mastic in Ebernoe

Is Ebernoe within the area you cover?

Yes, Ebernoe is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

Can you do sand mastic in Ebernoe?

Yes. Our work covers London and the South East, and Ebernoe is part of that. Just ring 0345 464 0079 or send us an email with a few details of the job.

How do I get a quote for sand mastic in Ebernoe?

We do not publish prices, because the cost depends on the job: its size, the old material, access and the product needed. You will get a clear quote before any work starts.

Can you do several jobs on one visit?

Of course. Combining jobs makes good use of the visit.

Where are you based?

We work from Crawley. Our applicators cover Ebernoe, along with the rest of our area.

Are you insured?

Yes. Mr Mastic is fully insured, and we have been doing sealant work for more than 20 years.

What do you put in the joint?

Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we will explain our choice.

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

In most cases. We remove the silicone and clean the joint before the sand mastic goes in.

What we do, step by step

We work through the job in order: protect, prepare, seal, tidy. Typically it takes a few hours per window, depending on the condition of the joints. For a village or hamlet like Ebernoe, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.

  1. Each surround is checked first.
  2. The joint is raked out and cleaned.
  3. We fill deep gaps so the new mastic is not too thick.
  4. New sand mastic is applied and shaped by hand.
  5. We finish the mastic to a tidy line.

How to prepare

  • Keep pets and children clear of the area while we work
  • Mention any parking rules near the property
  • Mention if the joints have been sealed before

Should I try it myself first?

Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.

Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

What we are called out for in Ebernoe

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

It’s worth asking for a quote if you see:

  • Mastic worn away on windows facing the weather
  • Cement or filler used on old window joints that has cracked
  • Draughty sash windows at the surround
  • Mastic dropping out of the joint

For an older house near a landmark such as Holy Trinity Church, the joint between an old wall and a newer frame is normally the first place rain gets in.

What your quote should include

  • How the joint is cleaned and prepared
  • Is VAT in the price?
  • How hidden problems are handled
  • The length of the guarantee

Our hiring checklist

Frames and glazing around Ebernoe

London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Petworth House (about 3.7 miles south) nearby, there’s older building stock in the area around Ebernoe as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.

In and around Ebernoe, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.

Landlord and commercial work in Ebernoe

Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.

Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can be quoted together.

Leave it or put it right?

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 Ebernoe, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

The cost reflects the work involved, not guesswork. That is why we ask a few questions first and agree the price before starting.

When it isn’t the sealant

Some problems need a builder, plumber or other trade rather than us:

  • Broken panes
  • Crumbling stone or brickwork round the window
  • Whether work needs listed building consent
