Window mastic for homes and businesses in Surbiton Park

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 work on window sills, composite doors and aluminium frames, and common reasons people get in touch are a bead that doesn’t match the frame and black, perished sealant on frames.

Much of London’s older housing was built with timber sash windows, some still in place and some long since replaced. Whatever is in the opening now, the joint between frame and wall is what keeps the weather out, in Surbiton Park as anywhere.

All our work comes with our one-year guarantee.

Frames and glazing around Surbiton Park

With historic houses such as Hampton Court Palace (about 1.4 miles west) nearby, there’s older building stock in the area around Surbiton Park as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. In a converted house or block, who looks after the windows depends on the lease, so check that before booking.

For an older house near a landmark such as St John's Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. If you let a flat or house near Surbiton station, renewing tired window mastic between tenants heads off draught and damp complaints.

DIY versus a professional finish

Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.

How the job changes by surface

Patio & French doors

Not every patio door leak is a mastic problem: blocked drain slots, worn brush seals and threshold details can let water in too. We look for the cause first.

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.

Common problems we fix in Surbiton Park

Some failures date back to when the windows were fitted. Mastic laid onto dusty, damp or crumbling surfaces didn’t grip properly, and it lets go sooner than it should.

Look out for these signs:

  • Gaps left after new windows were fitted
  • White mastic on grey or black frames
  • Mastic that has split away from the wall
  • Cracked internal joints between frame and plaster

Surbiton Park is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

What your quote should include

  • What happens if the job turns out different
  • Whether the sealant suits the joint
  • How much experience the applicator has
  • How the surfaces are prepared before sealing

Choosing a sealant specialist

Leave it or put it right?

Getting a straight, even bead on an outside frame takes practice, especially upstairs. We cut out properly, back deep gaps and tool every joint neatly, in a sealant suited to the wall. In London conversions, one flat’s bathroom is often above another flat’s ceiling, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Putting it right early is much less trouble.

No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.

Why choose Mr Mastic in Surbiton Park

  • White, clear, grey or another colour, product permitting
  • Old sealant always removed completely
  • Neat joints and a tidy finish
  • Homes, businesses and hotels

Take a look at what affects the cost or customer reviews.

How to look after the new joints

A little care helps the new joints last. Our advice:

  • Keep jet washers away from the mastic
  • Avoid harsh chemicals near the mastic
  • Keep drainage slots and sill grooves clear
  • Walk round the house once a year and look at the joints

Silicone cannot normally be painted, so mention any painting plans before any work starts. We can use a paintable sealant where that matters.

Water gets in quietly when mastic fails. You might not see it until plaster blows or a damp patch appears inside. Early resealing stops it reaching that point.
