About our window mastic in Saunderton

Most frames have an outside joint and an inside one. The external joint is the weather seal; the internal joint closes the gap to the plaster and stops draughts. We seal one or both, depending on what’s needed. If you have hard, cracked sealant around windows and damp patches on the reveal after heavy rain, we can help, whatever the surface.

Outdoor sealant needs dry, clean surfaces, so work on frames around Saunderton is planned for dry weather. Let us know about access to all the frames, upstairs ones included.

All of our work is guaranteed for twelve months.

What we can’t put right

Sealant is not the answer to every problem, and we’d rather say so up front. Sealant will not put right:

  • Worn gaskets, brush seals or a door that has dropped
  • A sash or casement that will not close properly
  • 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.

What we seal

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

Surface by surface

Timber windows & doors

On period timber windows, traditional sand mastic is sometimes the better choice. We can talk through the options.

Composite doors

If the door itself is draughty, the issue may be the door seals or hinges rather than the frame mastic. We seal the frame and let you know about anything else.

Keeping the joints in good condition

To keep the joints looking good and working properly:

  • Clear any debris from frame drain holes
  • Don’t use solvent cleaners on the joint
  • Ventilate rooms so frames do not stay wet inside
  • Do not aim a pressure washer at the joints

Have a look at the joints once a year, ideally after winter. Cracks and lifting edges are easy to spot early, and if anything looks wrong, just call 0345 464 0079 or email us.

Water trapped behind a failed joint can start rot in timber frames and sills. Rotten timber needs a joiner, not a sealant, so it pays to reseal before that happens.

Windows and doors in Saunderton

With historic houses such as West Wycombe Park House (about 2.6 miles south) nearby, there’s older building stock in the area around Saunderton as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

For an older house near a landmark such as Church of St Paul, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. For site and facilities teams at buildings such as Bledlow Ridge School, larger buildings have plenty of frames, and the mastic around each one ages.

How the visit works

When we arrive, we start by going over the job with you, so you know exactly what we’re doing. Surfaces next to the work are protected before any work begins. Most jobs take a morning for a couple of windows and a door. In a small place like Saunderton, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. First we look at every frame and agree the list.
  2. We remove the old mastic and clean the frame and the wall.
  3. We fit backing rod in deep gaps so the sealant is the right depth.
  4. A flexible, weatherproof sealant is applied in a colour to suit the frame.
  5. Every joint is checked before we leave.

Getting ready for the visit

  • Mention any leaks or damp you’ve noticed
  • Where the joints are inside, avoid wetting them before we arrive
  • Clear items away from the joints we are working on

Getting a quote

A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and email photos if that’s easy.

When to call us in Saunderton

Some failures date back to when the windows were fitted. Sealant run over dust, wet brick or loose mortar didn’t grip properly, so it comes away long before its time.

Any of these means the joints need attention:

  • Whistling draughts around closed windows
  • Hard, cracked sealant around windows
  • Black, perished sealant on frames
  • Untidy mastic left by window fitters

For landlords with property near Saunderton station, renewing tired window mastic between tenants heads off draught and damp complaints.

What affects the quote in Saunderton

We quote each job individually. These are the things that affect it:

  • When we can work, for business premises
  • Whether there’s mould to deal with
  • The number of rooms or windows
  • How much old sealant there is and how hard it is to remove

What it costs depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before any work starts, so you know where you stand.

Asking for a quote

Photos help, but a description is a good start. Please mention:

  • A few photos by email, if you can
  • Any access issues, like height or stairs
  • If someone has resealed it before
  • Whether it’s a home or a business

Every job is quoted individually, so the first step is telling us about yours. Just phone 0345 464 0079 or drop us an email with the details and send pictures if you have them.
