How we handle window mastic in Beacon Hill

If you can feel air around a shut window, the gap is often at the frame. Resealing that joint can make a room feel noticeably less draughty and quietens the whistle on windy days. If the draught is through the window seals instead, we will tell you. If you have gaps where the sill meets the wall and cold air getting in at the frame edge, we can put it right.

Homes in small places like Beacon Hill 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.

A one-year guarantee comes as standard.

When to call us in Beacon Hill

On timber frames, paint and putty build up around the joint. Old mastic gets painted over and cracks under the paint, and the wood moves with damp as well as heat.

If you can see any of these, it’s time to have the joints looked at:

  • Draughts coming in around windows and doors
  • Gaps left after new windows were fitted
  • Cracked or shrunken mastic around the frame
  • Rain getting in at the frame or under the sill

If you look after a building such as Great Totham Primary School, the mastic around its windows and doors needs looking after like any other building’s.

Housing providers, facilities teams and property managers book us too in Beacon Hill and across Essex. We can quote a run of properties together.

What happens on the day

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 the size of the job. For a village or hamlet like Beacon Hill, 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. First we look at every frame and agree the list.
  2. The old mastic is cut out and the surfaces cleaned back.
  3. Deep gaps are filled with backing rod to set the depth.
  4. A flexible, weatherproof sealant is applied in a colour to suit the frame.
  5. Every joint is checked before we leave.

Preparing for the visit

  • Let us know about stairs, lifts or work at height
  • Tell us about any previous sealing or DIY attempts
  • Plan for the work area to be out of bounds to pets and children

Frames and glazing around Beacon Hill

London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

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

Your questions about window mastic in Beacon Hill

Can you do window mastic in Beacon Hill?

Yes, Beacon Hill is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or drop us an email and tell us what needs doing, and we’ll give you a clear price.

Do you cover smaller places like Beacon Hill?

Yes, Beacon Hill is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

Will resealing my frames help with draughts?

Often, yes. Air often gets in between the frame and the wall, and sealing the inside and outside joints closes that path.

Will it make a mess?

No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.

I rent my home. Can I book you?

We can work for tenants, landlords or agents. Just make sure your landlord agrees.

Does the work come with a guarantee?

Yes, with our one-year guarantee. Keeping drainage clear and checking the joints yearly helps them last.

Is the new sealant paintable?

Not generally, if it’s silicone. Tell us your decorating plans and we’ll pick a sealant to suit.

Do you take out the old sealant first?

Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.

Looking after it afterwards

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

  • Wipe condensation off the frames
  • Repaint timber before it’s bare
  • Look round the frames every year or so
  • 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.

A small gap around a frame only grows. As the old mastic shrinks further, more air gets through, and a cold room gets colder. A new joint closes it up.

Why it’s worth doing now in Beacon Hill

Working on frames from a ladder with a sealant gun is not easy, especially upstairs. We cut out properly, back deep gaps and tool every joint neatly, using a product chosen for the frame and wall. Older cottages and farmhouses around Beacon Hill can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

Combining jobs into one visit normally makes better use of the time than several visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.

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.

Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.

Surface by surface

uPVC windows

We clean the frame edge carefully so the plastic is not marked, then the new bead is laid against the frame and the wall and tooled smooth.

Window sills

Stone and concrete sills have their own joints, including the one between the sill and the frame above. Those are sealed with a product suited to stone or concrete.
