Windows and doors in Stoke Lyne

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.

If you let a flat or house near Bicester North station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. For an older house near a landmark such as Church of St Peter, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Surface by surface

Window sills

Where a sill meets brick or render, the ends often crack first. A tight seal at each end keeps rain out of the wall.

uPVC windows

The frame is cleaned with a product that won’t harm the plastic, then the new bead is laid against the frame and the wall and tooled smooth.

Why deal with it now?

Choosing the product is half the job. Decorators’ caulk and bathroom silicone are not designed for outside joints that move. A low-modulus exterior sealant keeps its stretch through hot and cold weather. Older cottages and farmhouses around Stoke Lyne can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please phone 0345 464 0079 or email us.

The process

Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes most of a day for a typical house, less for a few frames, and the area is left clean. Somewhere like Stoke Lyne needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.

  1. We check each frame and agree which ones need doing.
  2. Next the failed sealant is cut away and the joint cleaned.
  3. Where gaps are deep, backing rod goes in first.
  4. A flexible, weatherproof sealant is applied in a colour to suit the frame.
  5. Every joint is checked before we leave.

How to prepare

  • Mention any tricky access
  • Mention any parking rules near the property
  • Let us know about earlier repairs to the joints

Questions from Stoke Lyne

Is Stoke Lyne within the area you cover?

Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Can you do window mastic in Stoke Lyne?

Yes. We work across London and the South East, and Stoke Lyne is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job.

Do the sealants smell?

Some sealants have a smell while they cure, but it fades. Opening a window helps.

Do you take out the old sealant first?

Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.

How long before the joint can be used?

Cure times vary by product. We tell you how long to leave it before we go.

Where are you based?

Mr Mastic is based in Crawley. Our applicators cover Stoke Lyne.

What should I tell you?

The location, the problem and the rough size of the job. Photos by email help too.

Which products do you use?

It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.

Can I do it myself?

A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

What affects the cost of window mastic

Your quote is based on your job. We take into account:

  • The size of the job
  • The number of rooms or windows
  • Whether there’s mould to deal with
  • Working hours on commercial sites

Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.

Asking for a quote

To make quoting easier, let us know:

  • Whether it has been sealed before
  • A few pictures by email, if you can
  • Whether it’s a home or a business
  • What’s wrong with the joints now

Call for a quick quote, or email us if that is easier. Tell us about the joints that need doing and we will talk you through the work and give you a clear quote.

How to look after the new joints

Looking after new joints is easy:

  • Keep jet washers away from the mastic
  • Clean frames with a soft cloth and soapy water
  • Check the mastic once a year
  • Make sure the drainage slots are not blocked

Silicone can’t normally be painted, so if you’re planning to paint the frames or walls, tell us beforehand. There are paintable sealants for joints that need it.

Wet, windy weather is when failed mastic shows itself, but resealing works best in dry conditions. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.
