Frames and glazing around Tendring

Historic houses like Thorpe Hall (about 2.8 miles south-east) are a reminder that the area around Tendring has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

Schools such as Tendring Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s. If you live in an older home near Church of St Edmund, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

About our sand mastic in Tendring

We work across Tendring renewing sand mastic on sash windows and doors. Each joint is raked out, prepared and pointed by hand for a neat, traditional finish. Common call-outs are for failed mastic on an exposed elevation and old cement repairs round a window that have failed, across timber door frames, sash and case windows and brick reveals.

Homes in small places like Tendring often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.

The work is covered for a year after we finish. If anything isn’t right with it, call 0345 464 0079 or drop us an email.

Surface by surface

Period and listed homes

Many older homes were built with sand mastic round the windows. If your home is listed, ask your local planning authority about consent.

Stone surrounds

Old stone surrounds are often uneven, so the gap is not the same all the way round. Sand mastic is shaped by hand to suit.

What affects the cost of sand mastic

Jobs vary more than people expect. What affects the quote:

  • Which sealant suits the joint
  • Whether the work is at height
  • Any mould that needs treating
  • Working hours on commercial sites

Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you are not sure whether it needs doing, call 0345 464 0079 or send us an email and we will give you an honest view and a quote.

Asking for a quote

When you call or email, it’s useful to know:

  • The rough size of the job
  • Whether it’s a home or a business
  • Access, such as stairs, a lift or height
  • What the problem is, such as mould, gaps, leaks or cracking

For a quick quote, get us on the phone, or email us if that’s easier. Tell us about the joints that need doing and we’ll talk you through the work.

Work for landlords, hotels and businesses

Housing providers, facilities teams and property managers book us too in Tendring and across Essex. Several sites can be quoted together, and we’re fully insured.

We work for letting agents and landlords as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.

Keeping the joints in good condition

A little care helps the new joints last. We recommend:

  • Look over the window mastic once a year
  • Find out about consent before window work on a listed home
  • Do not run silicone over sand mastic
  • Have rotten timber repaired before new mastic goes in

Avoid painting over the new mastic, as traditional guidance advises. If you are redecorating, ask us first.

It’s best to renew mastic before painting the windows. Paint over cracked mastic only covers it up.

How the visit works

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 anything from a few hours to a full day, depending on how many windows.

  1. We check each window surround and the condition of the joint.
  2. We rake out the old mastic and clean the joint.
  3. Large voids are packed out.
  4. We point the joint with sand mastic by hand.
  5. We finish the mastic to a tidy line.

Getting ready for the visit

  • Plan for the work area to be out of bounds to pets and children
  • Let us know about parking restrictions
  • Mention any sign-in or site rules at work premises

10 questions to ask before you book

Can I do it myself?

If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.

A DIY attempt doesn’t rule out a professional job. We cut it out and start again.
