Window mastic for Steephill homes and businesses

Why act early in Steephill

Redecorating is a good moment to renew the mastic. A clean new bead makes new paint or render look finished. Around Steephill, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

Window mastic in Steephill, done properly

Most frames have an outside joint and an inside one. The external joint is the weather seal; inside, the joint between frame and plaster stops draughts and tidies the reveal. We seal one or both, depending on what’s needed. We work on window sills, composite doors and uPVC windows, and the jobs we see most are cracked sealant at the sill ends and cracked internal joints between frame and plaster.

In a village or hamlet like Steephill, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.

Big or small, it’s backed by our one-year guarantee in Steephill and across the Isle of Wight.

Questions from Steephill

Do you work for landlords with property near Shanklin station?

Yes, we work for letting agents and landlords. You can phone 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before work begins.

Is Steephill within the area you cover?

Yes. Steephill is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.

What do you need from me for a quote?

A short description and the location, with photos by email if possible. We will ask anything else we need to know.

When is the sealant fully cured?

It depends on the product. We tell you how long to leave it before we go.

Is it worth trying it myself?

That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.

Do I have to be there?

That depends on where the joints are. For work indoors, someone needs to let us in.

How long will my window job take?

Allow most of a day for a typical house, less for a few frames. Access and how stubborn the old mastic is affect the time most.

Can you get sealant to suit coloured frames?

Yes. We can use white, brown, anthracite grey, black or clear, so the joint suits the frame.

What we are called out for in Steephill

Joint shape matters as much as the product. A thin smear across a wide gap has nothing to it, and a gap filled solid can’t flex. That is what backing rod is for.

Look out for these signs:

  • Whistling draughts around closed windows
  • Cracked or shrunken mastic around the frame
  • Draughty joints inside around the window
  • White mastic on grey or black frames

Letting a property close to Shanklin station? Then renewing tired window mastic between tenants heads off draught and damp complaints.

What your quote should include

  • What happens if they find a problem under the old sealant
  • Whether they’re fully insured
  • Whether they seal over old material or remove it
  • Whether VAT is included

Our hiring checklist

Frames and glazing around Steephill

Steephill is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. Historic houses like Rylstone Manor (about 3.2 miles north-east) are a reminder that the area around Steephill has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.

If you look after a building such as St Francis Catholic and Church of England Primary Academy, larger buildings have plenty of frames, and the mastic around each one ages. Homes close to Church of St. Alban-the-martyr include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Steephill is about 3 miles south-west of Shanklin, in the Isle of Wight.

How the visit works

Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for a handful of frames, longer for a whole house and we leave things clean and tidy. In a small place like Steephill, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We check how each frame can be reached safely.
  2. Old, cracked mastic is removed completely, along with any loose debris.
  3. Frame and wall are cleaned and must be dry before sealing.
  4. Deep voids are backed, then the sealant is gunned in.
  5. The joint is shaped to shed water and the area tidied.

Preparing for the visit

  • Tell us about any previous sealing or DIY attempts
  • Plan for the work area to be out of bounds to pets and children
  • Let us know about parking restrictions

Should I try it myself first?

Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.

Different surfaces, different methods

Window sills

Where a sill meets brick or render, the ends often crack first. A tight seal at each end keeps rain out of the wall.

Timber windows & doors

Timber moves with moisture as well as heat, so a flexible sealant is essential. The paint or stain needs to be sound where the sealant meets it.

What we cannot put right

We will always be straight with you, so here’s what sealant can’t fix:

  • Rotten timber, which needs a joiner first
  • Penetrating damp from a failed cavity tray or render
  • Worn gaskets, brush seals or a door that has dropped

If you’re not sure, just phone 0345 464 0079 or drop us an email and we’ll give you a straight answer before booking.
