General Contractor Cardiff

Finding a reliable general contractor in Cardiff feels harder than it should be. You've probably been let down before — tradespeople who don't show up, quotes that double by the end, or jobs left half-finished. J & Z Property Maintenance is different. We've been serving homeowners and businesses across Cardiff and South Wales for years, and our reputation is built on doing what we say we'll do — and doing it well. If your property needs work, you're in the right place. Call 02920 123456 now and we'll have someone with you fast.

Most people come to us when something has already gone wrong. A damp patch that's spreading. Cracks in the wall that weren't there six months ago. A bathroom that's been half-tiled for two years because the last contractor walked off the job. These things don't fix themselves.

Cardiff homes — especially the older terraced properties in Roath, Pontcanna, and Canton — often come with their own set of headaches: ageing stonework, outdated drainage, and internal layouts that haven't been touched since the 1970s. You might notice doors that won't close properly, floors that have started to slope, or external render that's cracking and letting moisture in. These are all warning signs that a professional needs to take a look.

DIY can handle the small stuff. But when it comes to structural work, major renovations, or anything involving water and electrics, a half-done job almost always costs more to fix than hiring a pro from the start. South Wales weather is unforgiving — damp is quick to exploit any weakness. Don't let a small issue become a big bill.

We cover the full range of property work. Whether you need a single job or a team to manage a whole project, we have the tradespeople to handle it.

Our Property Maintenance service keeps your home or commercial space in good shape all year round — from fixing minor wear-and-tear to managing scheduled upkeep programmes. If you've had storm damage or structural movement, our Building Repairs team will assess and fix the problem properly, not just patch it up. We also carry out full Home Renovations, transforming rooms or entire properties to match how you actually want to live.

When walls need to come down or a new layout is needed, our Structural Work team handles it safely and to specification. We manage all the proper checks so you don't have to worry. Our Extensions and Conversions service adds real value to your home — loft conversions, rear extensions, and garage conversions done to a high standard with full project management included.

For landlords and letting agents, our Landlord Maintenance packages keep your properties compliant and your tenants happy. We also offer professional Plastering and Rendering for interior and exterior finishes, Painting and Decorating to finish any space cleanly and professionally, and Groundworks and Drainage for anything at or below ground level including patios, paths, and drainage solutions.

Cardiff is a city of contrasts — Victorian terraces in Cathays and Roath sit alongside new-build developments in Pontprennau and the Bay. Each type of property comes with its own challenges, and we know them all. Older homes often need rising damp treatment and period-appropriate materials. New builds sometimes need remedial work that should have been done during construction.

We work across all of Cardiff's neighbourhoods — from Whitchurch and Rhiwbina in the north, to the Bay and Grangetown in the south, and out into the Vale of Glamorgan and wider South Wales. Whatever part of the city or region you're in, we can usually reach you the same day. Our team is local, which means we understand the planning rules, the building styles, and the specific issues that Cardiff weather throws at properties year after year.

South Wales winters are wet. That means drainage, rendering, and waterproofing aren't optional extras — they're essential. We treat every job with that in mind.
