Plumbing questions, answered straight

Caldwellside Plumbing is based at Block 5, Unit 1, Caldwellside Industrial Estate, Lanark, ML11 7SR. We work across Lanark, Clydesdale and the wider Lanarkshire area, generally within about 15 miles of the town — including Carluke, Lesmahagow, Larkhall, Biggar, Forth, Carnwath, Douglas, Wishaw and Motherwell.

We cover Lanark and roughly a 15 mile radius around it. That includes Carluke, Crossford, Lesmahagow, Blackwood, Kirkmuirhill, Larkhall, Stonehouse, Strathaven, Biggar, Forth, Carnwath, Carstairs, Douglas, Coalburn, Shotts, Wishaw and Motherwell, plus the villages and hamlets between them.

Yes. Burst pipes, uncontrolled leaks, no water and no heating are treated as urgent and prioritised ahead of planned work. Call 01555 668284 and tell us what has happened, where the water is coming from and whether you have found the stopcock, and we will advise immediately.

Call 01555 668284 or send the details through our contact form with a few photos. Small repairs can often be priced over the phone. Bathrooms, heating systems and drainage work need a visit so the quote reflects the real job rather than a guess.

Yes. We carry out reactive repairs, planned maintenance and installation work for landlords, letting agents and local businesses, including commercial kitchens and washrooms. Work can be scheduled around tenants or opening hours, with paperwork provided for your records.

Urgent work in Lanark and the immediate ML11 area is usually attended the same day. Surrounding towns such as Carluke, Lesmahagow and Larkhall are typically same or next day. Planned work such as bathrooms and boiler replacements is booked to a date that suits you.

Turn off the water at the internal stopcock, usually under the kitchen sink or in a downstairs cupboard, then open cold taps to drain the system. Switch off electrics near the water and turn the heating off. Then call 01555 668284 with your postcode and what you can see.

In most cases, yes. We trace leaks by isolating sections of pipework, checking pressure and using acoustic and thermal methods before opening anything up. That keeps disruption and repair costs down and means we only lift flooring where the leak actually is.

Small repairs are usually priced as a call-out plus labour and parts, while larger jobs are quoted as a fixed price. We confirm the figure before starting work, so you are never guessing. Call 01555 668284 for a price for your specific job.

Yes. Older Lanark and Clydesdale properties often still have lead supply pipework. We replace it with modern copper or MDPE, reinstate the connection and make good afterwards. It improves water quality, flow rate and reliability all at once.

A typical full bathroom replacement takes about five to ten working days, depending on tiling, whether walls or floors are being moved and how much making good is needed. We give you a day-by-day plan before starting so you know when the room is usable again.

Either works. We can supply the suite, shower, tiles and fittings through our trade suppliers, or install items you have bought yourself. If you supply the goods, we check the specification first so nothing arrives that will not fit or perform properly.

Yes. We install low-profile and level-access showers, wet rooms, grab rails and seats for customers who need step-free access. We check floor construction and drainage falls first, as these determine whether a fully level tray or wet floor is achievable.

We handle the plumbing, tiling, flooring and waterproofing in-house and coordinate qualified electrical work for showers, lighting and extractors. You deal with one team from strip-out to final silicone rather than chasing separate trades.

Repeat blockages usually mean an underlying fault rather than bad luck: fat and scale build-up, root ingress, a collapsed or displaced pipe, or a poor fall on the run. A CCTV survey identifies the cause so the repair fixes the problem permanently.

Yes. We push a camera through the run, record the condition and locate defects and their depth. You get a clear explanation of what was found and what it will take to fix it — useful for repairs, insurance claims and pre-purchase checks.

Usually, yes. Blocked drains that are backing up into a property are treated as urgent. We rod or jet the run to restore flow, then advise whether a survey or repair is needed to stop it recurring.

In Scotland, public sewers are generally Scottish Water's responsibility, while pipework within your boundary is normally the property owner's. Shared private runs are usually a joint responsibility between the properties served. We can identify which section your problem sits in.

Cost depends on the boiler type, output, whether the system layout changes and how much pipework and flue work is needed. We survey the property, confirm the right size boiler and give a fixed written price including installation, controls and commissioning.

Cold at the top usually means trapped air and needs bleeding. Cold at the bottom points to sludge and corrosion debris settling in the radiator, which needs flushing and a magnetic filter fitted. Cold across whole zones is more often a pump or valve fault.

As a rule, repair is sensible for a boiler under about ten years old with available parts and a good service history. Beyond that, repeated repair costs and poor efficiency usually make replacement better value. We will tell you honestly which applies to yours.

Power flushing forces cleaning fluid through the system at high flow to remove sludge and corrosion debris. It is worth doing when radiators are cold at the bottom, the water runs black, or before fitting a new boiler onto an older system.
