About our window mastic in Netherburn

From a single sill to a whole house of windows, you will get a clear quote before any work starts. Just send an email to info@mrmastic.co.uk and tell us how many frames there are and how they’re reached for window mastic in Netherburn. If you have gaps where the sill meets the wall and mastic that has split away from the wall, we can help, on window sills, aluminium frames and patio & French doors alike.

Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Wind-driven rain finds any gap around a frame or sill, so the mastic there works hard.

The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

Your questions about window mastic in Netherburn

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

Yes. We work for landlords and letting agents as well as homeowners, and several properties can be quoted together. Just email us at info@mrmastic.co.uk with the address and what needs doing, and we will give you a clear price.

Is Netherburn within the area you cover?

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

Can you do several jobs on one visit?

Yes. Tell us about everything you’d like done and you’ll get one quote.

Can you match the sealant to my frames?

Normally, yes. Tell us the frame colour when you get in touch and we’ll use the nearest match.

Will there be a smell?

Some sealants have a smell while they cure, but it fades. Ventilation helps.

Does the work come with a guarantee?

Yes. Every job comes with our 12-month guarantee, and we’re ARBOMaster approved applicators.

Will new mastic stop draughts?

Yes, if the air is getting in around the frame. If it’s coming through the window seals, we will tell you.

Is it worth trying it myself?

For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.

When something else is needed

We’d rather tell you now than do work that will not last, so here’s what sealant can’t put right:

  • Penetrating damp from a failed cavity tray or render
  • Rotten timber, which needs a joiner first
  • Condensation trapped between the panes

Not sure which it is? You can send an email to info@mrmastic.co.uk and we will tell you honestly before booking.

Windows and doors in Netherburn

Sash and case windows are common in older Scottish homes, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic. With historic houses such as Cambusnethan House (about 3.5 miles north-west) nearby, there’s older building stock in the area around Netherburn as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.

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

When to call us in Netherburn

  • Mastic that’s falling out in pieces
  • Rushed sealant from a window installation
  • White mastic on grey or black frames
  • Damp patches on the reveal after heavy rain

Cambusnethan House, about 3.5 miles north-west, is one of the historic houses in the wider area around Netherburn, and older homes nearby need a sealant that suits their walls.

What your quote should include

  • Whether all the old sealant comes out first
  • How long the guarantee is
  • How long to leave it before use
  • Whether the sealant suits the joint

10 questions to ask before you book

Landlord and commercial work in Netherburn

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

We regularly work with letting and managing agents. Tell us the address, the job and how access works and we’ll give you a quote.

What happens if it’s left?

If you are painting or rendering, reseal at the same time. A clean new bead makes new paint or render look finished, and it’s easier while the walls are being worked on anyway. Around Netherburn, water from a failed joint in an older stone home can soak into timber and plaster.

A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

What affects the quote in Netherburn

The price is agreed before any work begins. It takes into account:

  • The size of the job
  • The type of sealant required
  • Whether old sealant or filler has to be cut out
  • The number of rooms or windows

Combining jobs into one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.

What we need to know

Photos help, but a description is a good start. Try to tell us:

  • Whether it’s a home or a business
  • Any access issues, like height or stairs
  • Roughly how big the job is
  • A few photos by email, if you can

The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints.

Looking after it afterwards

Joint life depends on how it’s used and looked after. We suggest:

  • Check the mastic once a year
  • Clear any debris from frame drain holes
  • Air rooms to keep condensation down around windows
  • Keep jet washers away from the mastic

Have a look at the joints once a year, ideally after winter. Small splits are simple to catch before they leak, and if anything looks wrong, just send an email to info@mrmastic.co.uk.

On timber windows, water behind the joint can lead to rot. Rotten timber needs a joiner, not a sealant, so early resealing is worth it.

The process

A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, do the work and tidy away. It usually takes most of a day for a typical house, less for a few frames. Around Netherburn, distance and access matter more than parking. 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. 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.

How to prepare

  • Mention any leaks or damp you’ve noticed
  • Keep pets and children clear of the area while we work
  • Mention if the joints have been sealed before
