Looking after it afterwards

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

  • Check the mastic once a year
  • Wash the frames with mild soapy water
  • Keep drainage slots and sill grooves clear
  • Repaint timber before it’s bare

Check the drainage slots in the frames aren’t blocked, so rain drains out rather than building up at the sealant.

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.

How we quote for window mastic

For a quick quote, just ask. The main things that affect it are:

  • The number and length of the joints
  • How many rooms, windows or areas are involved
  • Working hours on commercial sites
  • Whether the work is at height

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

What to tell us for a quote

There’s no need for technical detail. Just tell us:

  • Where the job is, and your postcode
  • A few photos by email, if you can
  • The rough size of the job
  • Whether it has been sealed before

Every job is quoted individually. Simply email us at info@mrmastic.co.uk and describe the job and send photos if you have them.

Do you need window mastic in Auchenharvie?

Plenty of failed mastic was poorly applied in the first place. Mastic laid onto dusty, damp or crumbling surfaces didn’t grip properly, and it lets go sooner than it should.

These are the problems we are asked about most:

  • Draughty joints inside around the window
  • Cracked sealant at the sill ends
  • Gaps left after new windows were fitted
  • Draughts coming in around windows and doors

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

Questions to ask before you book

  • When the joint can take water or movement
  • How the colour is chosen
  • What preparation is included
  • Is the old sealant removed completely?

10 questions to ask before you book

DIY sealant or a professional job?

Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.

Questions from Auchenharvie

Does the coastal weather in Auchenharvie affect outside sealant?

Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.

Do you cover smaller places like Auchenharvie?

Yes, Auchenharvie is covered. We work across all of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.

Can you get sealant to suit coloured frames?

Yes, we choose a colour to suit the frame. Grey and black frames get grey or black sealant, and wood-effect frames usually suit brown.

Do you do commercial work?

Yes. Commercial and hotel work is a large part of what we do, as well as homes. Working times can be discussed when we quote.

Can you reach windows above the ground floor?

Yes, as long as they can be reached safely. Let us know about access when you ask for a quote so we can plan the job.

Are you an approved applicator?

Yes. We are an ARBOMaster approved applicator.

Do you take out the old sealant first?

Yes, always, and completely. New silicone does not stick to old silicone, so the joint is cleaned back first.

I’m a tenant. Can you help?

We can work for tenants, landlords or agents. Just make sure your landlord agrees.

How it works

All our tools and materials come with us in the van, so you do not need to buy or prepare anything. Once we’ve agreed what’s being done, the area is protected and the work begins. It normally takes a few hours for a handful of frames, longer for a whole house. Outdoor work around Auchenharvie depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Work indoors is not affected.

  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.

Before we arrive

  • Move anything stored near the joints
  • Mention any tricky access
  • Mention any leaks or damp you’ve noticed

What happens if it’s left?

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. Wait for damp to appear and there may be plaster and decorating to sort out too. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.

The cost 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 work begins.

  • We never seal over old sealant

What sealant work cannot fix

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

  • Draughts through the window seals rather than the frame
  • A failed sealed unit that has misted up
  • A sash or casement that won’t close properly

If you’re not sure, just email us at info@mrmastic.co.uk and we will give you a straight answer.

Joints and surfaces we work on

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

Windows and doors in Auchenharvie

Auchenharvie is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on the mastic around window and door frames, especially on the side facing the sea. 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.

Letting a property close to Saltcoats station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.
