Your Local Team in St Mellons
MB Construction is a St Mellons business. Our address is Crumlin Drive, CF3 0EF, and a good share of our work happens within a couple of miles of it: Old St Mellons, the Began Road side, Pontprennau, Llanrumney, Trowbridge and Rumney.
Working on your own doorstep changes how you work. Reputation here is word of mouth between neighbours, so jobs get finished properly and we come back if anything needs a second look.
The area mixes eighties and nineties estate housing with older properties out towards Old St Mellons and the lanes beyond. Estate roofs are reaching the age where concrete tiles, felt and roofline timbers start needing attention, while the older properties bring slate, render and solid-wall work.
We cover roofing, rendering and EWI, block paving, resin driveways, patios, fencing, jet washing, kitchens, bathrooms, painting and decorating. All of it quoted free and fixed in writing, carried out by our own team of five, and backed by a 10-year workmanship guarantee.
- Where we work from
- Crumlin Drive, St Mellons, Cardiff. St Mellons is part of our regular working area, alongside Old St Mellons, Llanrumney, Rumney, Pontprennau, Castleton, Cardiff, Newport.
- Eighties and nineties estate housing
- Concrete tiled roofs, uPVC or timber rooflines and small front gardens. Most of these roofs are at the age where flashings, valleys and verges start to need attention.
- Older Old St Mellons property
- Out towards the village and the lanes there is slate, render and solid wall construction that needs traditional repair rather than modern shortcuts.
- Rear extensions and conservatories
- Very common across the area, and the flat roofs and junctions on them are the most frequent source of leaks we get called to locally.
- Driveways and front gardens
- Off-street parking is the standard ask here: block paving and resin-bound drives, often replacing worn tarmac or a lawn.
What We Get Called Out For Most in St Mellons
Roof repairs on maturing estate roofs
Slipped tiles, cracked mortar bedding and worn flashings on roofs of a similar age across whole streets.
Drive and patio upgrades
Resin and block paving to replace tired surfaces, usually with jet washing and a tidy of the surrounding paths at the same time.
Fencing after windy spells
Open estate layouts catch wind, and boundary fences are often the first casualty.
Inside work through winter
Kitchens, bathrooms, painting and decorating; the jobs people book locally once the outside is sorted.

The Problems St Mellons Properties Actually Have
Building age, ground conditions and how exposed a property is all change what fails first, and what the right fix is.
Whole streets ageing together
Estate housing was built at once, so it fails at once. When one neighbour needs valley or flashing work, the houses either side usually will soon after.
Flat-roof extension failures
Older felt on rear extensions hardens and splits at the upstand. Water then tracks back along the joists and shows up well away from the actual fault.
Exposed, open aspects
Parts of St Mellons sit open to wind coming across the levels, ridge tiles, verges and fence panels take a beating.
Heavy, slow-draining ground
Ground around here holds water. Driveways and patios need real sub-base depth and proper falls, or they move and pond within a couple of winters.
Moss and algae on paving
Shaded paths and north-facing drives go green fast. Jet washing keeps them safe rather than slippery.

Where exactly are you based?
Crumlin Drive, St Mellons, Cardiff CF3 0EF. If you are local, you are as close to us as it gets.
Do you actually cover St Mellons?
Yes. St Mellons is part of our regular working area. We are based at Crumlin Drive in St Mellons, Cardiff, and work across Cardiff, Newport, the Vale of Glamorgan, Caerphilly and Penarth, so St Mellons is a normal short trip rather than a long-distance job we reluctantly take on.

Yes. Quotes and site visits in St Mellons are free and carry no obligation. We look at the job in person and put a fixed price in writing; there is no charge for coming out and no pressure to book.
How much does the work cost in St Mellons?
Price depends on the property and the scope, so we do not publish figures we could not stand behind. What we can promise is how it is priced: a fixed quote for the job, never a day rate, so the number does not climb while the work is underway.
Can you get to St Mellons in an emergency?
We are available 24 hours a day, 7 days a week for emergency roof repairs, including active leaks and storm damage. Call and we will tell you honestly when we can be with you rather than making a promise we cannot keep.

Every job carries a 10-year workmanship guarantee: roofing, rendering and driveways alike. That guarantee is the same in St Mellons as it is anywhere else we work.
Are you insured?
Yes. We carry both public liability and employer's liability insurance, and we are happy to show you the documents before anyone sets foot on your property.

Will you tidy up afterwards in St Mellons?
Yes. Waste goes with us, the working area is cleared, and we walk the finished job with you before we leave.
Do you do small jobs locally?
Yes. A handful of slipped tiles, a fence panel or a patio clean are all worth doing properly, and being nearby makes small local jobs practical for us.
