How to choose a mastic man

Sand mastic in Best Beech Hill

Our applicators renew the sand mastic around sash and case windows and doors set in stone or brick. Out comes the old, loose mastic, the joint is prepared and new mastic is shaped by hand. We work on stone surrounds, sash and case windows and brick reveals, and common reasons people get in touch are mastic dropping out of the joint and draughty sash windows at the surround.

Homes in small places like Best Beech Hill often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.

There’s a 12-month guarantee on every job, whatever its size.

Work for landlords, hotels and businesses

We work for landlords and letting agents as well as householders. Sealant work between tenants keeps a property looking cared for before the next move-in.

A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.

What sand mastic looks like in Best Beech Hill

With historic houses such as Wadhurst Castle (about 1.4 miles east) nearby, there’s older building stock in the area around Best Beech Hill as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. 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 Uplands Community College are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. For landlords with property near Wadhurst station, cracked sand mastic around sash windows lets in the draughts tenants complain about.

How it works

There’s no need to move everything out before we come, just the space around the work. Everything nearby is protected, and the work takes a few hours per window, depending on the condition of the joints in most cases. In a small place like Best Beech Hill, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. First, we look at the surrounds with you and agree what needs doing.
  2. We rake out the old mastic and clean the joint.
  3. Large voids are packed out first, so the mastic is not too thick.
  4. We mix the sand mastic and apply it by hand, shaping it to the joint.
  5. The finish is dressed so it sits neatly against the stone or brick.

Preparing for the visit

  • Try not to wet indoor joints just before the visit
  • Mention any sign-in or site rules at work premises
  • Mention any leaks or damp you’ve noticed

Best Beech Hill: your questions answered

Is Best Beech Hill in your area for sand mastic?

Yes. We work across London and the South East, and Best Beech Hill is part of that. You can phone 0345 464 0079 or email us and let us know what needs doing.

Do you cover smaller places like Best Beech Hill?

Yes. Best Beech Hill is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

How long does sand mastic take?

Typically it takes anything from a few hours to a full day, depending on how many windows. Larger jobs naturally take longer, and we will tell you how long to expect.

Will there be a smell?

That depends on the sealant. Some smell for a while, some hardly at all.

Does someone need to be in?

For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.

What guarantee comes with the work?

You get our 12-month guarantee on every job.

Is consent needed for window work on a listed home?

Check with your local planning authority. They’ll tell you if consent is needed.

Can landlords and businesses book you?

Yes, regularly. We can quote for several properties at once.

Why deal with it now?

Cement-based fillers and modern sealants do not always suit a period surround. Sand mastic is the like-for-like choice and that can be important for listed homes. In a small place like Best Beech Hill, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

Why book with us

  • Every job guaranteed for a year
  • We leave the area clean and tidy
  • Homes, businesses and hotels

Quotes for sand mastic in Best Beech Hill

Some jobs are bigger than they look, and some smaller. What affects the quote:

  • Any working-time requirements on site
  • The old material and how stubborn it is
  • Access and height
  • The number and length of the joints

Combining jobs into one visit generally makes better use of the time than several visits. We will give you a clear price for the lot.

What we need to know

A few details help us give you an accurate quote. When you ask for a quote, tell us:

  • Pictures of the joints, sent by email
  • The type of property
  • Any previous sealing or DIY work
  • The address or postcode of the job

Call for a quick quote, or send an email if you’d rather. Describe what needs sealing and we’ll explain what’s involved before giving you a price.

Keeping the joints in good condition

So the new joints stay in good condition:

  • Do not run silicone over sand mastic
  • Inspect the joints round the windows every year or so
  • Sort the mastic before the decorators arrive
  • Get any rot dealt with first

Leave the new mastic unpainted, as traditional guidance advises. If you’re redecorating, ask us first.

Once mastic starts to crumble, rain gets in. It can soak into the frame and the surrounding masonry so early renewal protects both.

What the job involves on each surface

Sash and case windows

A sash window’s box frame sits in the masonry opening. Sand mastic seals the joint round it.

Period and listed homes

Many older homes were built with sand mastic round the windows. On listed buildings, check with your planning authority first.
