Sand mastic in Wimbish

If your home is listed or in a conservation area, check with your local planning authority whether consent is needed for work to windows. Sand mastic is often favoured as a like-for-like material. If you’re dealing with failed mastic on an exposed elevation and draughts and rain around sash boxes, we can help.

In a village or hamlet like Wimbish, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.

All of our work is guaranteed for twelve months.

Your questions about sand mastic in Wimbish

Do you work for landlords with property near Newport (Essex) station?

Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we will give you a clear quote.

Is Wimbish within the area you cover?

Yes. Wimbish is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.

Are you an approved applicator?

Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.

Do I have to be there?

If the work is inside, we need someone to let us in. Once we have agreed the job, you do not need to watch us work.

Is it messy?

We keep the work tidy. We protect what’s around the joints, and we clear up when we’re done.

Do you remove the old sealant?

Yes, always, and completely. New sealant won’t bond properly to old, so the joint is cleaned back first.

Which is right for my windows, sand mastic or modern sealant?

Sand mastic normally suits period timber windows best. On modern frames, we’d normally use a flexible sealant, and we will explain why.

Is consent needed for window work on a listed home?

Checking first is sensible. Ask your local planning authority whether consent is needed for listed or conservation-area properties.

Can I do it myself?

If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

How to look after the new joints

So the new joints stay in good condition:

  • Ask us before painting near the mastic
  • Avoid heavy scraping on the mastic joint
  • Have rotten timber repaired before new mastic goes in
  • Clear gutters so water does not pour onto the windows

Keep paint scrapers and sanders off the mastic when redecorating. Hard scraping can loosen it.

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

Signs you need sand mastic in Wimbish

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

People normally contact us when they notice something like this:

  • Draughty sash windows at the surround
  • Mastic dropping out of the joint
  • Silicone on a period window that looks wrong
  • Gaps round a timber door in stone or brick

Managing a site like Wimbish Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages.

What your quote should include

  • What insurance they hold
  • Who turns up on the day
  • How the joint is cleaned and prepared
  • Whether they seal over old material or remove it

How to choose a mastic man

What happens if it’s left?

Before painting the windows, it pays to renew the mastic. Paint over cracked mastic won’t stop the gaps, and the new mastic is traditionally left unpainted. Where a wall is exposed, as many are in small places like Wimbish, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

The cost reflects the work involved, not guesswork. That’s why we ask a few questions first and send you a clear quote before we start.

Why choose Mr Mastic in Wimbish

  • Trusted Arbo and Everbuild sealants
  • Domestic, commercial and hotel work
  • Anti-fungal silicone where joints get wet
  • We leave the area clean and tidy

Windows and doors in Wimbish

The South East is one of 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 Horham Hall (about 4.1 miles south) nearby, there’s older building stock in the area around Wimbish as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.

Homes close to St Paul's Mission Room include some older properties, and 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 Newport (Essex) station, any sash windows need sound mastic to keep draughts and rain out.

How it works

Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes a few hours per window, depending on the condition of the joints and we leave things clean and tidy. Somewhere like Wimbish 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. First we agree which joints need doing.
  2. Old mastic and any loose material are raked out.
  3. We pack any deep voids first.
  4. The sand mastic is mixed and pressed into the joint by hand.
  5. The surface is finished to suit the stone or brick.

How to prepare

  • Plan for the work area to be out of bounds to pets and children
  • Tell us if parking is tricky
  • For indoor joints, keep the area dry beforehand if you can
