How we handle sand mastic in Hainault

A silicone bead around a sash window can look out of place and does not suit the building. Sand mastic gives a finish that matches the age of the house, and we can replace one with the other. Typical jobs include mastic dropping out of the joint and open joints round the window box, on timber door frames, period & listed homes and brick reveals.

Many houses in smaller places like Hainault have conservatories, garden rooms or patio doors. Their glazing joints and frame seals are as much a part of the job as the windows, and any older timber or sash windows need a sealant that suits them.

There’s a 12-month guarantee on every job.

Quotes for sand mastic in Hainault

Jobs vary more than people expect. The main factors:

  • How much there is to do
  • Whether there’s mould to deal with
  • The type of sealant required
  • Any working-time requirements on site

A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

  • If it’s domestic, commercial or a hotel
  • Any previous sealing or DIY work
  • The address or postcode of the job

Sand mastic in Hainault: local notes

Historic houses like Valentines Mansion (about 2.4 miles south-west) are a reminder that the area around Hainault has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. 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.

For site and facilities teams at buildings such as Limes Farm Junior School, the mastic around its windows and doors needs looking after like any other building’s. Letting a property close to Seven Kings station? Then older sash windows in a rental need their mastic kept sound to keep the weather out.

Common problems we fix in Hainault

Water gets into small cracks in the mastic and loosens it further. Windows facing the weather tend to go first.

If you can see any of these, it’s time to have the joints looked at:

  • Gaps round a timber door in stone or brick
  • Mastic worn away on windows facing the weather
  • A silicone bead on a sash window that spoils the look
  • Draughts and rain around sash boxes

Homes close to St Francis of Assisi include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.

What your quote should include

  • When the joint can take water or movement
  • Which sealant they’ll use, and why
  • Whether VAT is included
  • How much experience the applicator has

Choosing a sealant specialist

Can I do it myself?

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.

A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Hainault: your questions answered

Can you help a landlord with a rental near Seven Kings station?

Yes, we work for landlords and agents. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before we start.

Can you do sand mastic in Hainault?

Yes, Hainault is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or send us an email and let us know what needs doing.

Can I choose the sealant colour?

In most cases you can choose. We’ll explain which colours are available.

Can I do it myself?

You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.

Do you work for hotels and businesses?

Yes. We have worked for hotels, offices and other businesses and we’re fully insured.

Should I check with the council before work on a listed or conservation-area home?

Checking first is sensible. Ask your local planning authority whether consent is needed for work on a listed home or in a conservation area.

Is it OK to seal over old sealant?

No, because it fails. We remove every bit of old sealant first.

Do you hold any approvals?

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

Honest limits

Honest advice matters more to us than a booking, so here’s what sealant cannot fix:

  • Damaged stone surrounds
  • Putty and glazing repairs
  • Decayed frames that need repair

Not sure which it is? You can call 0345 464 0079 or send us an email and we’ll tell you honestly.

What we seal

  • Brick reveals
  • Period & listed homes
  • Stone surrounds
  • Tenement windows
  • Timber door frames
  • Sash and case windows

What happens if it’s left?

An open joint round the frame lets weather in. Water can get to the frame and the masonry so renewing it early protects the window. Homes in smaller places like Hainault can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.

Doing several joints on one visit normally makes better use of the time than several visits, so tell us about everything that needs sealing. We’ll send you a clear quote for the lot.

The process

On the day, there’s very little for you to do. Show us the job and we will take it from there. The job generally takes a few hours per window, depending on the condition of the joints, including the tidy-up. For a job in Hainault, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.

  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. We finish the mastic to a tidy line.

How to prepare

  • Mention if the joints have been sealed before
  • Let us know about parking restrictions
  • For business premises, tell us about site rules or sign-in

Advice

Aftercare tips

Looking after new joints is easy:

  • Look over the window mastic once a year
  • Keep modern sealant off the mastic
  • Take care around the mastic when scraping paint
  • Renew mastic before redecorating the windows

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

Fine cracks show the mastic is starting to fail. Renewing it then is simpler than waiting until it falls out.
