  • Sashes that rattle, stick or won’t open
  • Timber that has rotted

What the job involves on each surface

Period and listed homes

Period homes look their best with traditional materials.

Tenement and terrace windows

Windows above ground floor need the right access. Let us know the floor and we’ll confirm access.

What we do, step by step

You don’t need to clear the whole room or building before we come, only the area right around the joints. Everything nearby is protected, and the work takes anything from a few hours to a full day, depending on how many windows for a typical job. Somewhere like Rivenhall End needs a little journey planning: 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.

Preparing for the visit

  • Tell us about any water getting in
  • For business premises, tell us about site rules or sign-in
  • Tell us about access, such as stairs, a lift or high-level joints

FAQs for Rivenhall End

Do you cover Rivenhall End for sand mastic?

Yes. We work across London and the South East, and Rivenhall End is part of that. Just phone 0345 464 0079 or email us with a few details of the job.

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

Yes. We work for letting agents and landlords as well as householders, and several properties can be quoted together. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear price.

What information do you need?

Only a few details: the address or postcode, what’s wrong and any access issues. Then call 0345 464 0079 or email us.

Will you leave a mess?

Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.

Are you an approved applicator?

Yes. We are approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.

What’s sand mastic made of?

Sand plus a binder based on linseed oil. It’s applied by hand and finished to sit neatly against the masonry.

Do you remove the old sealant?

Yes, always, and completely. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.

Do you guarantee sand mastic work?

You get our 12-month guarantee on every job.

Why it’s worth doing now in Rivenhall End

Not every filler suits an old window surround. Sand mastic is the like-for-like choice, which can matter on listed and conservation-area homes. Where a wall is exposed, as many are in small places like Rivenhall End, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

What it costs depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before work begins, so you know where you stand.

Why book with us

  • An ARBOMaster approved applicator
  • Homes, businesses and hotels
  • More than 20 years in sealant work
  • We never seal over old sealant

For landlords and businesses

Landlords and agents in Rivenhall End can book us as well as householders. Resealing between tenancies keeps a property looking cared for before the next move-in.

We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.

Can I do it myself?

If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly.

The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.

Rivenhall End homes and the weather

Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

Schools such as Rivenhall Church of England Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. If you let a flat or house near Witham station, cracked sand mastic around sash windows lets in the draughts tenants complain about. Homes close to Church of St Mary and All Saints include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Aftercare tips

To keep the joints looking good and working properly:

  • Ask a joiner to look at soft timber first
  • Make sure water runs off the sill
  • Sort the mastic before the decorators arrive
  • Inspect the joints round the windows every year or so

Look at the mastic when you look over the windows. Catching cracks early keeps repairs small.

Renewing mastic before redecorating saves doing it twice. Painting over failed mastic hides the problem for a while.
