Common questions in Mill Green

Will you come out to Mill Green?

Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Is Mill Green in your area for window mastic?

Yes. Our work covers London and the South East, and Mill Green is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job.

Will it make a mess?

Tidy work is part of the job. We protect what’s around the joints, and we clear up when we’re done.

Can you quote for more than one area?

Yes. Tell us about everything you’d like done and we’ll quote it together.

Can you seal the gap between the frame and the plaster indoors?

Yes, we do both. Inside, the joint between frame and plaster is sealed neatly, using a paintable sealant if you want to decorate.

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. If it does not work out, we can redo it.

Can you match the sealant to my frames?

Yes, we choose a colour to suit the frame. Anthracite grey, black, brown and white cover most frames, with clear as an option.

Are you fully insured?

Yes. Full insurance covers our work, and we can confirm the details when we quote.

Window mastic in Mill Green, done properly

Mr Mastic’s applicators have more than 20 years’ experience with window and door sealants. We are ARBOMaster approved and fully insured, and every job is covered by a 12-month guarantee. We work on timber windows & doors, aluminium frames and uPVC windows, and the jobs we see most are mastic that has split away from the wall and damp patches on the reveal after heavy rain.

Homes in small places like Mill Green 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.

All of our work is guaranteed for twelve months.

How the job changes by surface

Patio & French doors

Heavy door frames can move more than windows. The sealant must cope with it.

Composite doors

Front doors take the weather head on, and the top and bottom corners tend to fail first. Those corners get the most care.

Quotes for window mastic in Mill Green

Jobs vary more than people expect. What affects the quote:

  • Working hours on commercial sites
  • The old material and how stubborn it is
  • How many rooms, windows or areas are involved
  • The product the joint needs

Homes and businesses are quoted the same way: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we will go through it with you.

Asking for a quote

Photos help, but a description is a good start. Please mention:

  • The address or postcode of the job
  • What’s wrong with the joints now
  • Photos by email, if that is easy
  • How we’d reach the joints

Quotes start with a quick conversation. Describe the problem, the location and the size of the job, and we will talk you through what we’d do. Whenever you are ready, ring 0345 464 0079 or send us an email.

Signs you need window mastic in Mill Green

Frames are never completely still. Sun on a frame makes it expand, and it contracts again overnight, while the brick or render around it hardly moves. If the sealant can’t stretch, it splits.

The problems people generally mention when they call include:

  • Cold air getting in at the frame edge
  • Damp patches on the reveal after heavy rain
  • Hard, cracked sealant around windows
  • Draughty joints inside around the window

Letting a property close to Thatcham station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

What to look for in a quote

  • Is the old sealant removed completely?
  • How the surfaces are prepared before sealing
  • What happens if the job turns out different
  • Whether the sealant suits the joint

Choosing a sealant specialist

Landlord and commercial work in Mill Green

Landlords and agents in Mill Green can book us as well as homeowners. Resealing between tenancies keeps a property looking cared for before the next move-in.

If you manage several properties in or around Mill Green, jobs at different addresses can be quoted together. Just tell us the addresses and what each one needs, and pictures by email help.

When it isn’t the sealant

A few problems are outside what sealant work can do:

  • Worn gaskets, brush seals or a door that has dropped
  • Penetrating damp from a failed cavity tray or render
  • A frame that has rotted at the joint

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

Joints and surfaces we work on

  • Aluminium frames
  • Timber windows & doors
  • Patio & French doors
  • uPVC windows
  • Window sills
  • Composite doors

Aftercare tips

To keep the joints looking good and working properly:

  • Don’t paint over the silicone
  • Repaint timber before it’s bare
  • Walk round the house once a year and look at the joints
  • Clean frames with a soft cloth and soapy water

Keep the new mastic undisturbed while it cures, following the cure time we give you. Do not point a pressure washer at the joints.

Wet, windy weather is when failed mastic shows itself, but sealant goes on best when frames and walls are dry. Sorting cracked mastic early means the joint is sound before the bad weather.

How the visit works

Most of a good job is in the preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for a handful of frames, longer for a whole house. In a small place like Mill Green, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. First, we confirm safe access to each frame.
  2. Old, cracked mastic is removed completely.
  3. The surfaces are cleaned and left dry, and primed where the sealant calls for it.
  4. Backing rod fills deep voids and the sealant goes in on top.
  5. The joint is shaped to shed water and the area tidied.

How to prepare

  • For business premises, tell us about site rules or sign-in
  • Where the joints are inside, avoid wetting them before we arrive
  • Keep children and pets away from the work area

Advice

Mill Green homes and the weather

Historic houses like Shaw House (about 4.6 miles north-west) are a reminder that the area around Mill Green has older buildings as well as new. 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. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

Managing a site like Cheam School? Then the mastic around its windows and doors needs looking after like any other building’s. For an older house near a landmark such as Church of St Peter, the joint between an old wall and a newer frame is generally the first place rain gets in.
