Window mastic in Braidwood

Leave it or put it right?

Once mastic fails, rain can get between the frame and the wall. Over time that can mean damp patches, damaged plaster and rotting timber. Resealing now is a small job by comparison. In a place like Braidwood, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.

There are no prices on our website, because each job is priced on what it involves. For a quick quote, please drop us a line at info@mrmastic.co.uk and we will talk you through it.

How we handle window mastic in Braidwood

Mr Mastic’s applicators have more than 20 years’ experience with window and door sealants. We’re fully insured ARBOMaster approved applicators, and every job is covered by a 12-month guarantee. If you are dealing with cracked internal joints between frame and plaster and gaps where the sill meets the wall, we can put it right.

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 comes with our 12-month guarantee, wherever you are in South Lanarkshire.

Common questions in Braidwood

Is Braidwood within the area you cover?

Yes. Braidwood is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland. Let us know about access, parking and anything unusual about getting there when you book.

Do you cover Braidwood for window mastic?

Yes. Our work covers the whole of Scotland, and Braidwood is part of that. Just send an email to info@mrmastic.co.uk with a few details of the job.

Do you work for hotels and businesses?

Yes, regularly. We can plan bigger jobs in stages.

What do you need from me for a quote?

The location, the problem and the rough size of the job. If you can, email a few photos.

Do I have to be there?

If the work is inside, we need someone to let us in. After that, you can carry on with your day.

Can you seal the gap between the frame and the plaster indoors?

Yes. Draughts often come through the inside gap too, so it can be worth sealing both.

When is the sealant fully cured?

Many sealants skin over quickly but take longer to cure fully. We will give you the cure time for the product we used.

Can you quote for more than one area?

Yes, we can. Several rooms, windows or areas can go on one quote.

Common problems we fix in Braidwood

Older frames were often sealed with products that set hard. Once it’s rigid, every bit of frame movement pulls at it, leaving a hairline gap down one side.

Look out for any of the following:

  • Cracked sealant at the sill ends
  • Damp patches on the reveal after heavy rain
  • Cold air getting in at the frame edge
  • Cracked or shrunken mastic around the frame

If you look after a building such as Carluke High School, the mastic around its windows and doors needs looking after like any other building’s.

How to choose a mastic man

Aftercare tips

Once the sealant has cured, a few habits help it last:

  • Avoid blasting the frames with a pressure washer
  • Ventilate rooms so frames do not stay wet inside
  • Check the mastic once a year
  • Keep timber frames painted

Keep sill grooves and drainage slots clear, so water can run away instead of sitting against the joint.

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.

When something else is needed

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

  • Draughts through the window seals rather than the frame
  • A frame that has rotted at the joint
  • Faulty window hardware

If you’re not sure, just send an email to info@mrmastic.co.uk and we will give you a straight answer before booking.

What we seal

  • Composite doors

Windows and doors in Braidwood

Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that. 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 Carluke station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

DIY sealant or a professional job?

If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.

A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

The process

On the day, there’s very little for you to do. Show us the job and we will take it from there. The job generally takes a morning for a couple of windows and a door. Around Braidwood, distance and access matter more than parking. Tell us how to find the property and how to reach the work.

  1. First, we confirm safe access to each frame.
  2. All the failed sealant is cut away, along with any loose debris.
  3. Frame and wall are cleaned and must be dry before sealing.
  4. Deep voids are backed, then the sealant is gunned in.
  5. The joint is shaped to shed water and the area tidied.

Preparing for the visit

  • Plan for the work area to be out of bounds to pets and children
  • Tell us about any previous sealing or DIY attempts
  • Try not to wet indoor joints just before the visit
