Common problems we fix in Old Craighall

A lot of older mastic was never designed to stay flexible. Once it’s rigid, every bit of frame movement pulls at it, leaving a hairline gap down one side.

Signs it’s time to call us include:

  • Water coming in at the bottom corners of a door
  • Gaps left after new windows were fitted
  • Gaps where the sill meets the wall
  • Mastic that is falling out in pieces

Letting a property close to Musselburgh station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Our hiring checklist

Window mastic in Old Craighall, done properly

Every window and door frame has a gap around it, and mastic is what closes it. When it cracks, hardens or pulls away, draughts and rain get in. Our applicators cut it out and replace it with a flexible, weatherproof sealant. We work on aluminium frames, timber windows & doors and patio & French doors, and common reasons people get in touch are cracked internal joints between frame and plaster and mastic that has split away from the wall.

Many older Scottish homes still have timber windows set into stone walls. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.

We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

Old Craighall: your questions answered

I let a flat near Musselburgh station. Can you help?

Yes, rental work is part of what we do. Just email us at info@mrmastic.co.uk and tell us about the property, and we will give you a clear quote.

Does living near the coast affect window mastic in Old Craighall?

Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.

Will the old sealant be removed?

Yes, every time. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.

Can you do upstairs windows?

Yes, in most cases. Access is planned before we start.

Does the work come with a guarantee?

Yes. Every job comes with our one-year guarantee, and we’re fully insured.

Where do you work from?

We are a Crawley-based firm, with over 20 years’ experience. We work across South East England, London and Scotland.

How long does it take to reseal the windows on a house?

A few frames take a few hours. You will get a timescale with the quote.

Do you do commercial work?

Yes, regularly. Larger jobs can be planned room by room or area by area to suit the site.

What happens on the day

On the day, we look over the joints with you first, so there are no surprises. We protect the surfaces around the joints before any work begins. Most jobs take a few hours for a handful of frames, longer for a whole house. In smaller Scottish places, parking is usually 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. Where the gap is deep, backing rod goes in first.
  4. A flexible exterior sealant is applied in a colour to suit the frame.
  5. Every joint is tooled smooth and checked before we leave.

Preparing for the visit

  • Move anything stored near the joints
  • Mention any leaks or damp you’ve noticed
  • For indoor joints, keep the area dry beforehand if you can

What affects the quote in Old Craighall

There’s no set price list, because no two jobs are the same. What we look at:

  • Access and height
  • Any mould that needs treating
  • The amount of work
  • How many areas need sealing

No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.

Helping us quote

The more you tell us, the more accurate the quote. When you ask for a quote, tell us:

  • Where the property is
  • Pictures of the joints, sent by email
  • The rough size of the job
  • How we’d reach the joints

We quote each job on its own, so start by telling us what you need. Simply drop us a line at info@mrmastic.co.uk and describe the job.

What the job involves on each surface

Window sills

Stone and concrete sills have their own joints, and the joint under the frame can let rain run behind. Those are sealed with a product suited to stone or concrete.

Patio & French doors

The joints around patio doors run a long way, top, sides and threshold. Most leaks start at the bottom corners, so we pay close attention there.

Landlord and commercial work in Old Craighall

For anyone letting property in or around Old Craighall, jobs at different addresses can go on one quote. Send us the addresses and the work at each.

Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.

Aftercare tips

A little care helps the new joints last. We recommend:

  • Look round the frames every year or so
  • Do not paint over the silicone
  • Ventilate rooms so frames do not stay wet inside
  • Avoid blasting the frames with a pressure washer

Clean the frames with mild soapy water, and keep solvents and harsh chemicals off the joint.

On timber windows, water behind the joint can lead to rot. Rotten timber needs a joiner, not a sealant, so it pays to reseal before that happens.

DIY sealant or a professional job?

If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.

Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

What window mastic looks like in Old Craighall

Old Craighall is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on the mastic around window and door frames, especially on the side facing the sea. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.

Historic houses such as Melville Castle, about 2.6 miles south-west, show how far back building around Old Craighall goes. For site and facilities teams at buildings such as Loretto School, its window and door frames need their mastic kept sound, just like a home’s.
