Questions from Mill Meads

Can you help a landlord with a rental near West Ham station?

Yes, landlords and agents are among the people we work for. You can phone 0345 464 0079 or email us with the details for a clear quote.

Can parking be tricky for a visit in Mill Meads?

It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.

Can you seal over the old sealant?

No, because it fails. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.

Is the work guaranteed?

Yes. Every job comes with our one-year guarantee, and we’re fully insured.

Can resealing stop a draught around my window?

In many cases. Air often gets in between the frame and the wall, and resealing inside and out closes it.

Where is Mr Mastic based?

Our base is Crawley. We work across South East England, London and Scotland.

Do I have to be there?

We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.

Do you work for hotels and businesses?

Yes. Larger jobs can be planned room by room or area by area to suit the site.

Window mastic in Mill Meads

Frames and walls don’t move together. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. So the sealant has to stretch and recover, which is why we use a low-modulus product. Common call-outs are for draughts coming in around windows and doors and cracked or shrunken mastic around the frame, across uPVC windows, patio & French doors and window sills.

London homes have every kind of window, from timber sashes in period terraces to aluminium and uPVC in newer blocks. Over the years, the sealant around them shrinks, cracks and pulls away, which is when draughts and damp patches appear in homes in Mill Meads.

A 12-month guarantee comes with the work, just as it does everywhere we cover.

Looking after it afterwards

No joint lasts for ever, but care makes a real difference. A few tips:

  • Avoid harsh chemicals near the mastic
  • Walk round the house once a year and look at the joints
  • Keep paint and stain on wooden frames in good order
  • Avoid blasting the frames with a pressure washer

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

Water trapped behind a failed joint can start rot in timber frames and sills. Once wood has rotted, it needs repair before it can be sealed, so early resealing is worth it.

Work for landlords, hotels and businesses

From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.

We also work for property managers and facilities teams in Mill Meads and across Greater London. We can quote a run of properties together.

Why it’s worth doing now in Mill Meads

A quick bead over the top of old mastic looks like an easy fix, but it will not grip old, dirty sealant. It peels before long, and water still gets in behind. Proper resealing starts with removing the old joint. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and by the time it shows on a wall or ceiling in Mill Meads, the repair is bigger than the sealant job would have been.

The cost depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before work begins, so you know where you stand.

Why book with us

  • Trusted Arbo and Everbuild sealants
  • White, clear, grey or coloured to suit, where the product allows
  • Old sealant always removed completely
  • Fully insured

Should I try it myself first?

If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.

The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.

What we can’t put right

Honest advice matters more to us than a booking, so here’s what sealant can’t fix:

  • Condensation trapped between the panes
  • Broken hinges, locks or handles
  • Worn gaskets, brush seals or a door that has dropped

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

Surfaces we seal

  • Aluminium frames
  • Window sills
  • uPVC windows

Window mastic in Mill Meads: local notes

In London conversions and blocks, the lease decides who is responsible for the frames, so check that before you book. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

For site and facilities teams at buildings such as East London Science School, the mastic around its windows and doors needs looking after like any other building’s. In the older streets around St Mary's Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Mill Meads is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

The process

You don’t need to clear the whole room or building, just the space around the work. We protect the rest, and the work takes a few hours for a few frames, or a day or more for a whole house for a typical job. For a job in Mill Meads, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor we’re working on and whether there’s a lift.

  1. We check how each frame can be reached safely.
  2. Old, cracked mastic is removed completely, along with any loose debris.
  3. The surfaces are cleaned and left dry.
  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.

Before we arrive

  • Clear items away from the joints we are working on
  • Keep children and pets away from the work area
  • Tell us about any water getting in

Advice

Different surfaces, different methods

uPVC windows

We clean the frame edge carefully so the plastic isn’t marked, then the sealant goes in between frame and wall and tooled smooth.

Patio & French doors

Not every patio door leak is a mastic problem: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We check before we reseal.
