External & façade joints in Law, South Lanarkshire
Specialist external mastic for Law: careful preparation, the right product and tidy work. Call for a quick quote.
- Moss and dirt in joints with no sealant left
- Water getting into walls through failed joints
- Joints with sealant missing in places
Looking after it afterwards
After the cure time, these simple habits help:
- Get split or bare joints resealed while the damage is small
- Check the sealant is paintable before painting near it
- Keep soil, plants and ivy away from the joints
- Point out the joints to other trades
Keep pressure washers away from the sealant. High-pressure water can lift the edges and let water in behind.
A joint that has stopped moving pushes the movement elsewhere, often as cracks near the joint. Resealing it early helps prevent that.
How we handle external mastic in Law
Ground-floor and low-level joints are straightforward to reach. For joints higher up, give us some details of the building and we will confirm what access is needed. If you are dealing with moss and dirt in joints with no sealant left and old sealant gone brittle and cracked, we can put it right.
Across smaller places in Scotland, stone and harled cottages, farm buildings and newer houses often stand exposed to wind and rain. Gutter joints and wall joints take a battering.
There’s a 12-month guarantee on every job, large or small.

Why it’s worth doing now in Law
Done well, a resealed joint is a neat, straight line that suits the wall. A rushed bead with no backing looks untidy and doesn’t last, so it pays to do it properly once. In a place like Law, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
What it costs depends on the size of the job, how much old material has to come out and access to the work. You’ll have a clear quote before any work starts.

Do you need external mastic in Law?
Weeds, moss and debris in a joint are a sign the sealant has gone. Roots and dirt hold water against the wall.
Keep an eye out for any of the following:
- Sealant pulling away from one side of the joint
- Plants rooting in failed movement joints
- Failed sealant between panels on a façade
- Rigid filler in a joint that should flex
Schools such as Coltness High School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing.

What external mastic looks like in Law
Historic houses like Cambusnethan House (about 2.5 miles west) are a reminder that the area around Law has older buildings as well as new. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
For landlords with property near Carluke station, split movement joints are easy to miss on a rental until damp shows inside. Homes close to Overtown Parish Church include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain.
Law is about 2 miles north-west of Carluke, in South Lanarkshire. Law gets the same service as everywhere we cover: the old material taken out, joints prepared properly and a 12-month guarantee. 139 places in South Lanarkshire are on our list. For nearby work, see our Glasgow page.
We work across the ML8 postcode area for external mastic. Local streets include Station Road, Strath Dearn and Strath Carron, and we cover them all. Main roads around Law include the B7011, which makes travel easy. Close by, we work in Wildmanbridge (1 mile north-east), Bogside (1 mile north-east), Chapel (2 miles north-east), Morningside (2 miles north) and Cambusnethan (2 miles north). Within a short drive, we also cover East Kilbride (12 miles west), Hamilton (7 miles west), Cambuslang (11 miles north-west), Uddingston (9 miles north-west), Blantyre (9 miles west) and Larkhall (4 miles west).
Near you in Law
For rail, the closest station is Carluke station, roughly 1.9 miles south-east of the centre. A little further out are Law Hospital (1 mile north-east) and Mauldslie Castle (1.5 miles south-west). Not far away are Baron's Haugh RSPB Reserve and Allanton House lake.
Should I try it myself first?
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.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.

Questions from Law
Can you help a landlord with a rental near Carluke station?
Yes. We work for landlords and agents as well as householders, and several properties can be quoted together. You can email us at info@mrmastic.co.uk with the details for a clear quote.
Do you cover smaller places like Law?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
How often do external joints need resealing?
It depends on the exposure, the movement and the product. Sealant is a maintenance item, so check the joints once a year and renew it when it starts to fail.
Is it OK to fill a movement joint with cement?
No. Mortar locks the joint solid, so the wall cracks somewhere else instead. Use a flexible sealant with backing rod.
Are you fully insured?
Yes. We are fully insured for every job we do.
Will the new joint stand out?
We aim for a joint that suits the wall rather than one that jumps out. Colour is agreed with you before we begin from the range available.
Do you remove the old sealant?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Is the work guaranteed?
Yes: twelve months. If anything isn’t right with the work within the year, let us know and we will sort it.
How it works
We bring everything the job needs with us. Once we have agreed what’s being done, the area is protected and the work begins. Most jobs take a few hours to a few days, depending on the length of joint and the access. 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.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
How to prepare
- Let us know if you’ve seen damp or leaks
- Let us know about parking restrictions
- On commercial sites, let us know about site rules
