Work for landlords, hotels and businesses

Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. Several properties can be quoted together.

In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.

Sand mastic for homes and businesses in New England

We renew sand mastic around sash windows and doors in stone and brick. Out comes the old, loose mastic, the joint is prepared and new mastic is shaped by hand. If you have failed mastic on an exposed elevation and silicone on a period window that looks wrong, we can put it right, whatever the surface.

Outdoor sealant needs dry, clean surfaces, so work on frames around New England is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.

Every job is covered by a one-year guarantee, wherever you are in Essex.

Windows and doors in New England

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.

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

New England is in Essex. Anywhere in CO9, our applicators can take on sand mastic. New England is one of 644 places in Essex we cover. For nearby work, see our Chelmsford page.

We work across CO9 for sand mastic and the streets around it. If you’re just outside New England, we cover Birdbrook (1 mile south). We also work in nearby towns such as Braintree (13 miles south), Saffron Walden (11 miles west), Halstead (10 miles south-east), Great Dunmow (14 miles south-west), Great Notley (14 miles south) and Bocking (12 miles south).

Around New England

New England questions

What guarantee comes with sand mastic in New England?

All our work, in New England and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.

Is New England in your area for sand mastic?

Yes. We work across London and the South East, and New England is part of that. You can call 0345 464 0079 or send us an email and let us know what needs doing.

Can you do several jobs on one visit?

Yes, and it often makes sense. Combining jobs makes good use of the visit.

Is there any odour?

Sometimes, a little. Any smell clears as the sealant cures.

Do you do commercial work?

Yes, regularly. We can plan bigger jobs in stages.

Do you take out the old sealant first?

Yes. All of the old material is cut out and the joint cleaned.

Where is Mr Mastic based?

Our base is Crawley. Our area covers South East England, London and Scotland.

Will you leave a mess?

Very little: the area around the joints is protected first, and we tidy up before we go.

What we are called out for in New England

Timber swells and shrinks with the weather. The movement cracks the mastic over time.

The problems people usually mention when they call are:

Mastic round period door frames that has failed
Modern sealant on a period surround
Crumbling sand mastic round a window
Mastic that needs renewing before redecorating

Around New England, as everywhere, sand mastic is only as good as the preparation behind it.

Our hiring checklist

What the job involves on each surface

Brick reveals

Loose mastic comes out and deep gaps are packed before pointing.

Tenement and terrace windows

Rows of sash windows on tenements and terraces often need renewing together. We work on single windows or whole elevations.

The process

The work is kept neat and contained to the area we’re working on, so you can carry on as normal. The job usually takes a few hours for a single window, longer for several, and we tell you how long to leave it before we go. Somewhere like New England needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.

Each surround is checked first.
We rake out the old mastic and clean the joint.
Large voids are packed out.
We point the joint with sand mastic by hand.
The finish is dressed neatly.

Before we arrive

Try not to wet indoor joints just before the visit
Clear the area around the work
Mention any parking rules near the property

Quotes for sand mastic in New England

We quote each job individually. These are the things that affect it:

Access and height
Whether there’s mould to deal with
Whether old sealant or filler has to be cut out
The type of sealant required

Doing several joints on one visit normally makes better use of the time than several visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.

Asking for a quote

There’s no need for technical detail. It helps if you can tell us:

How many joints, rooms or windows are involved
The address or postcode of the job
The type of property
If someone has resealed it before

We quote each job on its own, so start by telling us what you need. Simply phone 0345 464 0079 or email us and describe the job.

Leave it or put it right?

An open joint round the frame lets weather in. Left, water can reach the timber and the wall, so dealing with it now protects both. Older cottages and farmhouses around New England can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
