Questions from Lauder
Is Lauder within the area you cover?
Yes. Lauder is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
Do you work for landlords with property near Stow station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just send an email to info@mrmastic.co.uk with the address and what needs doing, and we will send you a clear quote.
Does someone need to be in?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Can I add another job to the visit?
Yes. Tell us about everything you’d like done and we will quote it together.
Do you have sealant for grey or black windows?
Yes. Anthracite grey, black, brown and white cover most frames, with clear as an option.
Will resealing my frames help with draughts?
Yes, where the draught is at the frame edge. We find where the air is coming from before we reseal.
Do you work on first-floor windows?
Yes, as long as they can be reached safely. Tell us about access when you get in touch and we’ll plan for it.
Will there be a smell?
There can be a smell while the sealant cures, which fades as it sets. Opening a window helps.
About our window mastic in Lauder
The mastic around a window or door seals the gap between the frame and the wall. When it cracks, hardens or pulls away, draughts and rain get in. The old mastic is removed and the joint resealed with a flexible exterior sealant. Common call-outs are for rushed sealant from a window installation and a bead that doesn’t match the frame, across composite doors, aluminium frames and timber windows & doors.
Outdoor sealant needs a dry surface, so window work around Lauder is planned around the weather. Let us know about access to every frame, including any upstairs.
You’re covered for a year from the day we finish. If there’s a problem with it, please email us at info@mrmastic.co.uk.

Window mastic in Lauder: local notes
Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
If you live in an older home near St Mary's Parish Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Lauder is about 8 miles north of Galashiels, in the Scottish Borders. We provide window mastic to householders, landlords and businesses in Lauder and the surrounding area, as part of our work across the Scottish Borders. Our the Scottish Borders coverage runs to 89 places, Lauder among them. We also work in Edinburgh, about 24 miles from Lauder.
All of TD2 is covered for window mastic, from the main roads to the quietest streets. You will find streets such as Market Place, West High Street and East High Street. With the A68 and B6362 close by, Lauder is simple for us to get to for window mastic.

Near you in Lauder
The nearest railway station is Stow station, about 5 miles south-west. A little further out are Thirlestane Castle (under half a mile north-east). The countryside around Lauder includes Addinston Hill.
Why deal with it now?
Not every sealant suits a window. Decorators’ caulk and bathroom silicone aren’t designed for outside joints that move. A low-modulus exterior sealant keeps its stretch through hot and cold weather. Around Lauder, water from a failed joint in an older stone home can soak into timber and plaster.
There are no prices on our website, because each job is priced on what it involves. Call for a quick quote and we’ll talk you through it.

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Keep jet washers away from the mastic
- Keep paint off silicone joints
- Look round the frames every year or so
- Wipe condensation off the frames
Try not to touch the new joint while it cures, following the cure time we give you. Do not point a pressure washer at the joints.
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.

Signs you need window mastic in Lauder
Mastic ages in the weather. Sunlight dries the surface out, until it loses its stretch and starts to crack.
Signs it’s time to call us include:
- Rushed sealant from a window installation
- White mastic on grey or black frames
- Damp patches on the reveal after heavy rain
- Leaking joints at the ends of sills
Letting a property close to Stow station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Can I do it myself?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
How the job changes by surface
Timber windows & doors
Older timber windows in stone or brick can suit sand mastic rather than modern sealant. We will tell you which suits your home.
Patio & French doors
The joints around patio doors run a long way, top, sides and threshold. Most leaks start at the bottom corners, so they get particular care.
