Looking after it afterwards

Aftercare is simple, and it makes a real difference:

  • Keep jet washers away from the mastic
  • Air rooms to keep condensation down around windows
  • Use gentle cleaners on frames and sealant
  • Don’t paint over the silicone

Keep the new mastic undisturbed while it cures, following the cure time we give you. Keep jet washers away from the frames.

Signs to watch for: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. Any of these is worth a call.

Window mastic in Thorley Street

Over two decades of sealing frames has taught us which products suit which walls. We are ARBOMaster approved and fully insured, and every job is covered by a 12-month guarantee. We are often asked to deal with cracked internal joints between frame and plaster and leaking joints at the ends of sills, across aluminium frames, window sills and uPVC windows.

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

The work is covered for a year after we finish. If anything isn’t right with it, phone 0345 464 0079 or send us an email.

Why it’s worth doing now in Thorley Street

A cracked joint around a frame lets rain into the wall. Left long enough, it can stain inside walls, spoil plaster and rot wooden frames. A reseal is a much smaller job. In a small place like Thorley Street, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

The cost reflects the work involved, not guesswork. That is why we ask a few questions first and give you a clear quote before we start.

Why Thorley Street clients choose us

  • A sealant colour to suit the surroundings
  • An ARBOMaster approved applicator
  • We never seal over old sealant
  • Arbo and Everbuild products

What happens on the day

On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The job generally takes a morning for a couple of windows and a door from start to finish. In a small place like Thorley Street, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. Each frame is looked over and we agree which ones need resealing.
  2. The old mastic is cut out and scraped back to clean surfaces.
  3. Where the gap is deep, backing rod goes in first.
  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 about stairs, lifts or work at height
  • Mention any sign-in or site rules at work premises
  • Move anything stored near the joints

DIY sealant or a professional job?

What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.

Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Landlord and commercial work in Thorley Street

Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. We can quote for more than one property at once.

Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we’ll give you a quote.

How the job changes by surface

uPVC windows

Some uPVC windows were sealed at fitting with a quick bead that never bonded. We cut it out, back any deep gaps and reseal properly.

Aluminium frames

Aluminium needs a sealant that bonds to coated metal, and acetoxy silicones aren’t used, as they can attack some metals. Neutral-cure sealant is the safe choice.

Window mastic in Thorley Street: local notes

Thorley Street is within about 2 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on the mastic around window and door frames, especially on the side facing the sea. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

Around Thorley Street, as everywhere, window mastic is only as good as the preparation behind it. For an older house near a landmark such as St. Swithin's Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
