Window mastic in Dunkeld

The process

A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and clear up. It usually takes anything from an hour or two to a full day, depending on how many frames there are. In smaller Scottish places, parking is generally less of an issue than access and distance. Let us know how to find you and how to reach the joints, and the visit is planned around that.

  1. First, we go round the frames with you and agree the list.
  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.

Preparing for the visit

  • Mention any sign-in or site rules at work premises
  • Let us know about parking restrictions
  • Keep pets and children clear of the area while we work

Advice

Window mastic for homes and businesses in Dunkeld

From a single sill to a whole house of windows, the work is priced before anything is done. To get one, email us at info@mrmastic.co.uk with the number of frames and any access details for window mastic in Dunkeld. Typical jobs include cracked or shrunken mastic around the frame and untidy mastic left by window fitters, across composite doors, patio & French doors and aluminium frames.

Older stone-built homes in Scotland often have sash and case or timber windows set in stone. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.

All our work is covered by our one-year guarantee.

Windows and doors in Dunkeld

Many older homes in Scotland have sash and case windows, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.

In and around Dunkeld, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.

Do you need window mastic in Dunkeld?

Every frame moves through the day. Sun on a frame makes it expand, and it contracts again overnight, while the brick or render around it hardly moves. A sealant that can’t keep up eventually tears.

People generally contact us after spotting one of these:

  • Draughts coming in around windows and doors
  • Untidy mastic left by window fitters
  • Hard, cracked sealant around windows
  • Water coming in at the bottom corners of a door

For landlords with property near Dunkeld & Birnam station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

10 questions to ask before you book

Work for landlords, hotels and businesses

From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.

We work for letting agents and landlords as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.

Aftercare tips

So the new joints stay in good condition:

  • Wipe condensation off the frames
  • Check the mastic once a year
  • Keep paint off silicone joints
  • Use gentle cleaners on frames and sealant

Have a look at the joints once a year, ideally after winter. Cracks and lifting edges are easy to spot early.

Draughts get worse, not better. As old mastic keeps shrinking, the gap widens, and a cold room gets colder. A new joint closes it up.

What affects the cost of window mastic

Your quote is based on your job. We look at:

  • The number and length of the joints
  • How many rooms, windows or areas are involved
  • How easy the joints are to reach
  • The type of sealant required

Doing several joints on one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.

Helping us quote

When you contact us, these details help:

  • Photos by email, if that is easy
  • What the problem is, such as mould, gaps, leaks or cracking
  • Whether it’s a home or a business
  • Any previous sealing or DIY work

Need a quote? Please send an email to info@mrmastic.co.uk with a few details. We will explain what we’d do and give you a clear quote before work begins.

Why deal with it now?

If you are painting or rendering, reseal at the same time. Fresh joints finish the job neatly. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.

What you pay reflects the work, not a rough estimate. That’s why we ask about the job first and agree the price before starting.

Why book with us

  • Sanitary silicone with an anti-fungal additive in wet areas
  • White, clear, grey or another colour, product permitting
  • Quality sealants from Arbo and Everbuild
  • Tidy, careful work

Can you get sealant to suit coloured frames?

Yes. We can use white, brown, anthracite grey, black or clear, so the joint suits the frame.

Different surfaces, different methods

Window sills

Masonry sills can have joints where water gets in, including the one between the sill and the frame above. We seal those with a sealant suited to masonry.

Aluminium frames

Metal frames expand in the sun and are often slim, with little room for error. A tidy bead in anthracite grey, black or a matching colour keeps the clean look.
