When something else is needed

Sealant isn’t the answer to every problem, and we’d rather say so up front. It will not solve:

  • Decayed frames that need repair
  • Masonry that needs repairing
  • Whether work needs listed building consent

If you are not sure, just ring 0345 464 0079 or drop us an email and we will give you a straight answer.

Joints and surfaces we work on

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

Sand mastic for homes and businesses in Milton Hill

Sand mastic does not last for ever and gaps open up round the frame. Renewing it closes the gap so the surround looks right again. We work on timber door frames, brick reveals and period & listed homes, and the jobs we see most are draughty sash windows at the surround and cracked mastic round a front door frame.

Mastic can only go onto a dry, clean joint, so window work in Milton Hill is booked around the forecast. Let us know about access to all the frames, upstairs ones included.

We stand behind the work with a 12-month guarantee.

What affects the cost of sand mastic

Your quote is based on your job. We take into account:

  • The old material and how stubborn it is
  • Which sealant suits the joint
  • Working hours on commercial sites
  • The number of rooms or windows

Homes and businesses are quoted the same way: the amount of work, the access and the products needed. Call for a quick quote and we’ll go through it with you.

Asking for a quote

Photos by email are helpful but not essential. Try to tell us:

  • The address or postcode of the job
  • The rough size of the job
  • Any access issues, like height or stairs
  • If it’s domestic, commercial or a hotel

For a quote, call 0345 464 0079 or drop us an email and tell us where the job is and what the problem looks like. We will give you a clear quote before any work starts.

Surface by surface

Brick reveals

Sand mastic is also used where timber frames meet brick. It suits older brickwork.

Tenement and terrace windows

In shared buildings, the windows may be part of a wider repair so it’s worth checking responsibilities.

Landlord and commercial work in Milton Hill

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 go on one quote.

A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.

What we’re called out for in Milton Hill

Sand mastic slowly weathers. It dries out, cracks and loses its grip from the frame or the masonry.

These are the problems we are asked about most:

  • Mastic dropping out of the joint
  • Modern sealant on a period surround
  • Tired mastic found when preparing windows for paint
  • Failed mastic on an exposed elevation

Homes close to Church of St Blaise 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

  • How the colour is chosen
  • What guarantee comes with the work
  • What the quote includes, VAT included or not
  • Whether the sealant suits the joint

How to choose a mastic man

Sand mastic in Milton Hill: local notes

Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

Letting a property close to Didcot Parkway station? Then any sash windows need sound mastic to keep draughts and rain out. If you look after a building such as St Blaise CofE Primary School, the mastic around its windows and doors needs looking after like any other building’s.

Can I do it myself?

If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.

Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

Milton Hill questions

Do you cover Milton Hill for sand mastic?

Yes. Our work covers London and the South East, and Milton Hill is part of that. You can ring 0345 464 0079 or email us and let us know what needs doing.

Can you help a landlord with a rental near Didcot Parkway station?

What guarantee comes with the work?

Our 12-month guarantee applies to all our work.

How long will you be here?

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

Can I add another job to the visit?

Yes, we can. More than one area can go on one quote.

What do you put in the joint?

We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we will tell you what we’re using.

Do you hold any approvals?

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

Do I need permission for sand mastic on a listed building?

Check with your local planning authority. They decide whether consent is needed for work to your windows.

What happens on the day

You do not need to clear the whole room or building, only the area right around the joints. We protect the rest, and the job takes a few hours per window, depending on the condition of the joints in most cases. For a village or hamlet like Milton Hill, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.

  1. We start by checking each surround and agreeing the joints to renew.
  2. Old, loose mastic is raked out and the joint cleaned.
  3. We pack any deep gaps so the mastic sits at the right depth.
  4. The mastic is mixed, pressed into the joint by hand and shaped.
  5. The finish is dressed so it sits neatly against the stone or brick.

Getting ready for the visit

  • Mention any tricky access
  • For business premises, tell us about site rules or sign-in
  • Mention if the joints have been sealed before
