Window mastic in Law, done properly
Whether it’s one leaking patio door or every frame on the house, you will get a clear quote before any work starts. Just email us at info@mrmastic.co.uk and tell us how many frames there are and how they’re reached. We work on timber windows & doors, patio & French doors and aluminium frames, and people most often call us about damp patches on the reveal after heavy rain and mastic that has split away from the wall.
In and around a place like Law, homes range from older stone-built cottages to newer houses. Wind-driven rain finds any gap around a frame or sill, so the mastic there works hard.
Your job is guaranteed for a year, as with all our work.

How the job changes by surface
Composite doors
Draughts round the door leaf generally come from worn seals or adjustment, not the mastic. We will tell you if that’s what we find.
Aluminium frames
Coated aluminium needs a compatible sealant, and acetoxy silicones are not used, as they can attack some metals. We use a neutral-cure product.

For landlords and businesses
Mouldy or split sealant often shows up at the end of a tenancy. We can quote for more than one property at once.
Landlords and agents in Law can book us as well as householders. Resealing between tenancies keeps a property looking cared for before the next move-in.
Leave it or put it right?
Not every sealant suits a window. Interior caulk and bathroom silicone aren’t made for exterior frame joints. An exterior, low-modulus sealant stays flexible in sun and frost. 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.
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we’ll go through it with you.

What we can’t put right
New sealant can’t fix everything, and we’d rather say so up front. It will not solve:
- A failed sealed unit that has misted up
- A sash or casement that won’t close properly
- A frame that has rotted at the joint
If in doubt, email us at info@mrmastic.co.uk and we’ll say what we think before you book.

How the visit works
You don’t need to clear the whole room or building before we come, only the area right around the joints. We protect the rest, and the work takes a few hours for a few frames, or a day or more for a whole house for a typical job. Somewhere like Law may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- We check how each frame can be reached safely.
- All the failed sealant is cut away.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- Clear the area around the work
- On commercial sites, let us know about site rules

Law homes and the weather
With historic houses such as Cambusnethan House (about 2.5 miles west) nearby, there’s older building stock in the area around Law as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
For landlords with property near Carluke station, renewing tired window mastic between tenants heads off draught and damp complaints. Schools such as Coltness High School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. In the older streets around Overtown Parish Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Law questions
Can you do window mastic in Law?
Yes, Law is within the area we cover. Our work covers the whole of Scotland. You can drop us a line at info@mrmastic.co.uk and let us know what needs doing.
Will you come out to Law?
Yes, Law is covered. Our work covers the whole of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
Do you have sealant for grey or black windows?
Yes. Grey and black frames get grey or black sealant, and wood-effect frames usually suit brown.
Do you work on first-floor windows?
Yes, where it’s safe. For high or awkward windows, we will tell you what access is needed.
Do you take out the old sealant first?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Will you leave a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Can I paint over the new sealant?
Not generally, if it’s silicone. Tell us your decorating plans and we will pick a sealant to suit.
Looking after it afterwards
So the new joints stay in good condition:
- Avoid harsh chemicals near the mastic
- Look round the frames every year or so
- Keep paint off silicone joints
- Keep jet washers away from the mastic
Keep sill grooves and drainage slots clear, so rain drains out rather than building up at the sealant.
A small gap around a frame only grows. As old mastic keeps shrinking, the gap widens, and a cold room gets colder. A new joint closes it up.
DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
