Window mastic in Balscote

How it works

We work through the job in order: protect, prepare, seal, tidy. Typically it takes most of a day for a typical house, less for a few frames. Somewhere like Balscote needs a little journey planning: 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. First, we go round the frames with you and agree the list.
  2. The old mastic is cut out and scraped back to clean surfaces.
  3. Deep gaps get closed-cell backing rod to set the depth.
  4. The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
  5. Every joint is tooled smooth and checked before we leave.

Before we arrive

  • Let us know if you’ve seen damp or leaks
  • Clear items away from the joints we’re working on
  • Tell us about access, such as stairs, a lift or high-level joints

Window mastic for homes and businesses in Balscote

Whether it’s one leaking patio door or every frame on the house, the work is priced before anything is done. To get one, call 0345 464 0079 or email us with the number of frames and any access details for window mastic in Balscote. We work on aluminium frames, window sills and patio & French doors, and common reasons people get in touch are leaking joints at the ends of sills and old mastic that has gone black or come away.

Around Balscote, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.

You’re covered for a year from the day we finish. If anything is not right with it, call 0345 464 0079 or email us.

What the job involves on each surface

Window sills

The end joints of a sill tend to fail before the rest. A tight seal at each end keeps rain out of the wall.

Patio & French doors

Door frames take knocks and movement every time the doors are used. The sealant must cope with it.

What sealant work can’t fix

We’d rather tell you now than do work that will not last, so these are the limits:

  • Condensation trapped between the panes
  • Soft or decayed wood in the frame
  • A door that needs adjusting, rehanging or new seals

If you’re not sure, just ring 0345 464 0079 or send us an email and we will give you a straight answer before you book.

Joints and surfaces we work on

Balscote: your questions answered

Is Balscote in your area for window mastic?

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

Will you come out to Balscote?

Yes, Balscote is covered. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

Is the new sealant paintable?

Most silicone cannot be painted. If you plan to paint, tell us first and we can use a paintable sealant where it suits the joint.

Are you fully insured?

Yes. We are fully insured, and we can confirm the details when we quote.

Do you work for landlords and businesses?

Yes. We work for householders, landlords, letting agents, businesses and hotels in Balscote.

Can you reach windows above the ground floor?

Yes, if safe access is possible. Higher or awkward frames may need extra access, and we will confirm what’s needed.

Can new sealant go over the old?

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

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

Yes. Draughts often come through the inside gap too, so sealing both is often worthwhile.

Why act early in Balscote

Draughts and leaks do not always mean new windows. If the frames and glass are in good order, resealing the joints is often all that is needed. If we find failed glass units or worn seals, we will tell you. Where a wall is exposed, as many are in small places like Balscote, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.

Keeping the joints in good condition

A little care helps the new joints last. Our advice:

  • Wipe condensation off the frames
  • Clear any debris from frame drain holes
  • Walk round the house once a year and look at the joints
  • Keep jet washers away from the mastic

Check the drainage slots in the frames are not blocked, so rain drains out rather than building up at the sealant.

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.

Balscote homes and the weather

With historic houses such as Upton House (about 2.8 miles north-west) nearby, there’s older building stock in the area around Balscote as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. 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.

In the older streets around Church of St Mary Magdalene, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Common problems we fix in Balscote

Water runs down the glass onto the sill, and the ends of the sill, where it meets the wall, are where it gets in. When that sealant fails, water gets into the wall or under the frame.

The problems people generally mention when they call include:

  • Gaps between the frame and the inside reveal
  • White mastic on grey or black frames
  • Mastic that’s falling out in pieces
  • Gaps where the sill meets the wall

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

Our hiring checklist

Should I try it myself first?

The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.

If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
