Window mastic in Laughton

When it isn’t the sealant

It helps to know what we can’t do too:

  • Worn gaskets, brush seals or a door that has dropped
  • Misting between the panes of a double-glazed unit (that needs a new unit)
  • Damp problems in the wall away from the window

Not sure which it is? You can ring 0345 464 0079 or email us and we’ll tell you honestly before booking.

Joints and surfaces we work on

  • Composite doors
  • Timber windows & doors
  • Aluminium frames
  • Window sills
  • Patio & French doors
  • uPVC windows

Window mastic in Laughton, done properly

Frames and walls do not 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. We’re often asked to deal with leaking joints at the ends of sills and cracked or shrunken mastic around the frame, on timber windows & doors, uPVC windows and patio & French doors.

Around Laughton, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.

We stand behind the work with a one-year guarantee.

DIY sealant or a professional job?

If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.

A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.

Keeping the joints in good condition

Once the sealant has cured, a few habits help it last:

  • Repaint timber before it’s bare
  • Check the mastic once a year
  • Wash the frames with mild soapy water
  • Do not paint over the silicone

A yearly look round the frames is enough. Small splits are simple to catch before they leak.

Signs to watch for: split or missing mastic, gaps, damp patches inside or black mould on the reveal. Any of these is worth a call.

Why act early in Laughton

Running fresh sealant over the old joint is tempting, but it won’t grip old, dirty sealant. It soon lifts and the leak carries on behind it. The old mastic has to come out. In a small place like Laughton, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Windows and doors in Laughton

The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Glyndebourne (about 3.4 miles south-west) are a reminder that the area around Laughton has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.

Letting a property close to Glynde station? Then renewing tired window mastic between tenants heads off draught and damp complaints. For an older house near a landmark such as The Parish Church of All Saints, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

What the job involves on each surface

uPVC windows

The frame is cleaned with a product that will not harm the plastic, then the sealant goes in between frame and wall.

Aluminium frames

Aluminium needs a sealant that bonds to coated metal and we avoid acetoxy silicones, which can react with some metals. Neutral-cure sealant is the safe choice.

The process

There’s no need to move everything out before we come, just the space around the work. We protect the rest, and the job takes anything from an hour or two to a full day, depending on how many frames there are for a typical job. For a village or hamlet like Laughton, 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 start by checking each window and door with you.
  2. We remove the old mastic and clean the frame and the wall.
  3. Where gaps are deep, backing rod goes in first.
  4. We apply a weatherproof sealant to match the frame and tool it neatly.
  5. Finally we tidy up and check each joint.

Before we arrive

  • Mention any leaks or damp you’ve noticed
  • Tell us if parking is tricky
  • Move anything stored near the joints

Signs you need window mastic in Laughton

Mastic ages in the weather. Sunlight dries the surface out, and over the years it loses its give, cracks and comes away.

Any of these means the joints need attention:

  • Cold air getting in at the frame edge
  • Black, perished sealant on frames
  • Cracked internal joints between frame and plaster
  • Mastic that has split away from the wall

Managing a site like Laughton Community Primary School? Then the mastic around its windows and doors needs looking after like any other building’s.
