Window mastic for Row Green homes and businesses

Surface by surface

Patio & French doors

Water at the foot of a door frame isn’t always the mastic: blocked drain slots, worn brush seals and threshold details can let water in too. We look for the cause first.

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.

When to call us in Row Green

Sills take more water than any other part of a window, and the ends of the sill, where it meets the wall, are where it gets in. Failed sealant there lets rain into the wall or behind the frame.

Keep an eye out for any of the following:

  • White mastic on grey or black frames
  • Black, perished sealant on frames
  • Gaps where the sill meets the wall
  • Rain getting in at the frame or under the sill

For site and facilities teams at buildings such as White Court School, larger buildings have plenty of frames, and the mastic around each one ages.

How it works

At the end, we look at the finished work together. The visit itself generally takes a morning for a couple of windows and a door, depending on how much there is to do. For a village or hamlet like Row Green, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.

  1. We check how each frame can be reached safely.
  2. All the failed sealant is cut away.
  3. Frame and wall are cleaned and must be dry before sealing, 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.

Preparing for the visit

  • Move anything stored near the joints
  • Let us know about earlier repairs to the joints
  • Mention any parking rules near the property

Questions from Row Green

Can you do window mastic in Row Green?

Yes. We work across London and the South East, and Row Green is part of that. You can call 0345 464 0079 or email us and tell us what needs doing.

I let a flat near Braintree station. Can you help?

Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can call 0345 464 0079 or drop us an email with the details for a clear quote.

Do the sealants smell?

Some sealants have a smell while they cure, which fades as it sets. Ventilation helps.

Can you seal over the old sealant?

No, and we never do. It may look fine at first, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.

Will the old sealant be removed?

Yes, always, and completely. New sealant will not bond properly to old, so the joint is cleaned back first.

Can you do upstairs windows?

Yes, where they can be reached safely. Let us know about access when you ask for a quote so we can plan the job.

What do you need from me for a quote?

Tell us what needs doing and where, with photos by email if possible. If we need more, we’ll ask.

Is it worth trying it myself?

Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.

Why act early in Row Green

Resealing frames is a short job: the visit takes most of a day for a typical house, less for a few frames. Wait for damp to appear and there may be plaster and decorating to sort out too. Around Row Green, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

Combining jobs into one visit is normally more efficient than separate visits. You will get one clear quote for the whole job.

Aftercare tips

How long the joints last depends on use and care. We suggest:

  • Wash the frames with mild soapy water
  • Clear any debris from frame drain holes
  • Walk round the house once a year and look at the joints
  • Do not aim a pressure washer at the joints

Clean the frames with mild soapy water, and avoid solvent cleaners on the sealant.

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. If you notice one, it’s time to get the joint looked at.

Windows and doors in Row Green

The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

Rented homes near Braintree station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Honest limits

In fairness, there are a few things sealant won’t fix:

  • A frame that has rotted at the joint
  • Misting between the panes of a double-glazed unit (that needs a new unit)
  • A door that needs adjusting, rehanging or new seals
