About our window mastic in Tyler's Hill

The mastic around a window or door seals the gap between the frame and the wall. When it cracks, hardens or pulls away, draughts and rain get in. Our applicators cut it out and replace it with a flexible, weatherproof sealant. We work on uPVC windows, aluminium frames and composite doors, and common reasons people get in touch are water coming in at the bottom corners of a door and sealant in the wrong colour for the frame.

Somewhere as small as Tyler's Hill, older homes often have timber frames set in stone or brickwork. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.

Big or small, you get the same 12-month guarantee.

How the visit works

We bring everything the job needs with us. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a few hours for a few frames, or a day or more for a whole house. For a village or hamlet like Tyler's 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. Each frame is looked over and we agree which ones need resealing.
  2. The old mastic is cut out and scraped back to clean surfaces.
  3. Deep gaps get closed-cell backing rod to set the depth.
  4. The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
  5. Every joint is tooled smooth and checked before we leave.

How to prepare

  • Try not to wet indoor joints just before the visit
  • Clear the area around the work
  • Mention any sign-in or site rules at work premises

Why deal with it now?

The work is quick compared with the damage it prevents: it takes a few hours for a few frames, or a day or more for a whole house. Leave it until water is coming in and you may need plastering and decorating as well. Older cottages and farmhouses around Tyler's Hill can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

Doing several joints on one visit is generally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We will send you a clear quote for the lot.

Why us?

  • Any old sealant cut out fully, not covered over
  • Tidy, careful work
  • 180+ five-star Google reviews
  • Domestic, commercial and hotel work

What we can’t put right

We won’t take on work that won’t last, so these are the limits:

  • Damp coming through the wall itself rather than the frame joint
  • Faulty window hardware
  • Misting between the panes of a double-glazed unit (that needs a new unit)

If in doubt, ring 0345 464 0079 or drop us an email and we will say what we think.

What we seal

  • Window sills
  • Composite doors
  • uPVC windows

Do you remove the old sealant?

Yes, always, and completely. New sealant will not bond properly to old, so any old material comes out before anything new goes in.

How to look after the new joints

Looking after new joints is easy:

  • Keep timber frames painted
  • Clean frames with a soft cloth and soapy water
  • Walk round the house once a year and look at the joints
  • Keep drainage slots and sill grooves clear

Wipe the frames with soapy water when you clean the windows, and keep solvents and harsh chemicals off the joint.

A small gap around a frame only grows. As old mastic keeps shrinking, the gap widens, and a cold room gets colder. Resealing closes it.

Signs you need window mastic in Tyler's Hill

Water runs down the glass onto the sill, so the sill ends and the joint below the frame are common leak points. When that sealant fails, water gets into the wall or under the frame.

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

  • Cracked sealant at the sill ends
  • Draughts coming in around windows and doors
  • Damp patches on the reveal after heavy rain
  • White mastic on grey or black frames

Schools such as Ley Hill School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

What your quote should include

  • How much experience the applicator has
  • What the cure time is
  • What happens if the job turns out different
  • What insurance they hold

How to choose a mastic man

DIY versus a professional finish

If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.

What window mastic looks like in Tyler's Hill

Historic houses like Chenies Manor House (about 3 miles south-east) are a reminder that the area around Tyler's Hill has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

For an older house near a landmark such as St George's Church, the joint between an old wall and a newer frame is normally the first place rain gets in. For landlords with property near Amersham station, renewing tired window mastic between tenants heads off draught and damp complaints.
