Your Local Team in Old St Mellons
Old St Mellons is our immediate neighbourhood. Our yard is on Crumlin Drive, so the village, Began Road, Ty'n-y-Parc, Druidstone Road and the lanes running out towards Michaelston-y-Fedw are all on our doorstep.
The property here is a different proposition to the estates nearby. There are period cottages and older village houses with natural slate, stone and lime-based render, larger detached homes on generous plots, and converted or extended buildings where old and new construction meet. That meeting point is usually where the weather gets in.
Work on older buildings needs the right approach rather than the quickest one: matched slates instead of mismatched patches, proper lead flashings and valley work instead of sealant, and render that suits the wall underneath instead of trapping moisture in it. We would rather explain why a repair is done a certain way than cut a corner you find out about in three winters' time.
Alongside that we lay block paved and resin-bound driveways, build patios, install fencing, jet wash, and fit kitchens and bathrooms with painting and decorating to finish. All of it quoted free as a fixed price, carried out by our own team of five, fully insured, and backed by a 10-year workmanship guarantee.
- Where we work from
- Crumlin Drive, St Mellons, Cardiff. Old St Mellons is part of our regular working area, alongside St Mellons, Pontprennau, Castleton, Cardiff.
- Period cottages and village houses
- Natural slate, stone walls, lime render and chimney stacks that are still in use. These want traditional materials and methods, not a modern shortcut.
- Larger detached homes on big plots
- Bigger roof areas, more complex layouts with dormers and hips, and long driveways and boundaries that need laying out properly.
- Extended and converted property
- Where a newer extension meets an older building, the junction, the flashing and the change in wall construction are where leaks start.
- Lane-side and rural-edge homes
- Exposed on at least one side, surrounded by mature trees, and dealing with far more leaf fall and moss than a sheltered street ever sees.
What We Get Called Out For Most in Old St Mellons
Slate roof repair and re-roofing
Matched slates, re-laid valleys, new lead flashings and re-bedded ridges, with a straight answer on whether repair or replacement is the better spend.
Chimney and leadwork
Repointing, haunching and flashing on stacks that are often the highest and most weather-beaten part of the building.
Long driveways and turning areas
Block paving and resin-bound surfacing over a sub-base built for the length and the traffic, with drainage designed rather than assumed.
Render, patios and garden walls
Render made good and breathable where the wall needs it, plus patios, paths and boundary work that suit the age of the property.

This is our village
Our address is Crumlin Drive, St Mellons, CF3 0EF. Work here is done under the eyes of our neighbours, which is the strongest incentive there is.
Older buildings done properly
Matched slate, proper leadwork and render chosen for the wall it is going on. More than 15 years of trade experience behind the decisions.
Big jobs staffed properly
A team of five means a large roof or a long driveway gets started and finished rather than left open to the weather.
Fixed price, free quote
We inspect in person, set out the work and give you a written figure. No day rates and no charge for coming out.
Insured and guaranteed
Public and employer's liability insurance in place, and a 10-year workmanship guarantee on the completed work.
The Problems Old 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.
Leaf fall blocking gutters and valleys
Mature trees along the lanes fill gutters and valleys every autumn. Water then backs up under the slate laps instead of running away.
Mismatched past repairs
Older roofs here often carry decades of patch repairs in the wrong material. Cement where lead should be is the classic, and it cracks every time.
Trapped damp behind hard render
Modern impermeable render on an older solid wall holds moisture in rather than keeping it out. The wall then stays wet and the render eventually blows.
Exposed gables on the rural edge
Once you are past the last houses there is nothing to slow the wind. Verges, ridges and chimney flashings take a beating on the exposed side.
Soft ground and long driveway runs
A long drive over soft ground needs depth and compaction throughout, not just at the entrance. Cutting that short shows up as ruts within a season.

Old St Mellons, Your Questions Answered
How close are you to Old St Mellons?
We are in it. Our yard is on Crumlin Drive, so a site visit to the village, Began Road, Druidstone Road or the surrounding lanes takes minutes.
Do you actually cover Old St Mellons?
Yes. Old 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 Old St Mellons is a normal short trip rather than a long-distance job we reluctantly take on.
Is the quote free in Old St Mellons?
Yes. Quotes and site visits in Old 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 Old 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 Old 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.
Is your work in Old St Mellons guaranteed?
Every job carries a 10-year workmanship guarantee: roofing, rendering and driveways alike. That guarantee is the same in Old 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.
How experienced is the team?
MB Construction has been trading since 2019 and the trade experience behind it runs to more than 15 years. The team is five strong, so jobs are properly staffed from start to finish.
Will you tidy up afterwards in Old 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 work on older and period properties?
Yes. Slate roofing, lead flashings and valleys, chimney work and traditional render are all part of what we do, with materials matched to the building rather than to whatever is quickest.
Can you lay a long driveway on a rural plot?
Yes. Longer runs need the dig, the sub-base and the drainage carried the full length. We set that out and price it as a fixed job before any work starts.
