What happens if it’s left?

A quick bead over the top of old mastic looks like an easy fix, but new sealant can’t bond to old, crumbling mastic. It peels before long, and water still gets in behind. Proper resealing starts with removing the old joint. 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.

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, and we will explain the quote if you ask.

Why book with us

  • Quality sealants from Arbo and Everbuild
  • Any old sealant cut out fully, not covered over
  • Fully insured
  • We agree the colour with you first

Window mastic in Wallaceton

Whether it’s one leaking patio door or every frame on the house, you will get a clear quote before any work starts. Just drop us a line at info@mrmastic.co.uk and tell us how many frames there are and how they’re reached. We work on timber windows & doors, patio & French doors and composite doors, and common reasons people get in touch are cracked sealant at the sill ends and draughts coming in around windows and doors.

In and around a place like Wallaceton, homes range from older stone-built cottages to newer houses. Wind-driven rain finds any gap around a frame or sill.

A one-year guarantee comes as standard.

When to call us in Wallaceton

Plenty of failed mastic was poorly applied in the first place. 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:

  • White mastic on grey or black frames
  • Leaking joints at the ends of sills
  • Black, perished sealant on frames
  • Draughty joints inside around the window

For jobs in and around Wallaceton, choosing the right material for each joint is as important as a tidy finish.

Before booking anyone

  • How much experience the applicator has
  • How long to leave it before use
  • Are they insured?
  • How the surfaces are prepared before sealing

How to choose a mastic man

DIY versus a professional finish

Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.

If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.

What we do, step by step

Good joint work is mostly preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work 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.

  1. We check how each frame can be reached safely.
  2. Old, cracked mastic is removed completely, along with any loose debris.
  3. The surfaces are cleaned and left dry, and primed where the sealant calls for it.
  4. Deep voids are backed, then the sealant is gunned in.
  5. We tool the joint so water runs off, then clear up.

Getting ready for the visit

  • Let us know about earlier repairs to the joints
  • Let us know if you’ve seen damp or leaks
  • Where the joints are inside, avoid wetting them before we arrive

Surface by surface

Timber windows & doors

Older timber windows in stone or brick can suit sand mastic rather than modern sealant. We’ll tell you which suits your home.

Aluminium frames

Metal frames expand in the sun and are often slim, with little room for error. A neat, narrow bead in a colour to match suits the frame.

Frames and glazing around Wallaceton

Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that. Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic.

Around Wallaceton, as everywhere, window mastic is only as good as the preparation behind it.

Honest limits

Some problems need a builder, plumber or other trade rather than us:

If in doubt, email us at info@mrmastic.co.uk and we’ll say what we think.

  • Composite doors

Keeping the joints in good condition

No joint lasts for ever, but care makes a real difference. Our tips:

  • Check the mastic once a year
  • Clean frames with a soft cloth and soapy water
  • Avoid blasting the frames with a pressure washer
  • Make sure the drainage slots aren’t blocked

A yearly look round the frames is enough. Cracks and lifting edges are easy to spot early.

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.
