Your Local Team in Llanrumney
Llanrumney sits directly between our base on Crumlin Drive and the rest of east Cardiff, so it is one of the areas we are in most often. Ball Road, Countisbury Avenue, Braunton Crescent, Bideford Road and the roads around Llanrumney Hall are a five minute run for us rather than a trip that has to be planned around traffic.
The housing here is mostly post-war: sturdy semis and short terraces with concrete interlocking tiles, roughcast or pebbledashed walls, timber or uPVC rooflines and generous gardens. Those roofs have now reached the age where the tiles themselves are often sound but the flashings, valleys, ridge bedding and felt underneath are not, which is exactly the point where honest advice saves money.
We handle new roofs and roof repairs, rendering and external wall insulation, block paving, resin driveways, patios, fencing, jet washing, kitchen fitting, bathroom fitting and painting and decorating. Using one team for the roof, the walls and the drive means the work is sequenced properly instead of three trades working around each other.
Every Llanrumney job is quoted free and in writing as a fixed price, never a day rate. We are insured for public and employer's liability, back completed work with a 10-year workmanship guarantee, and answer the phone 24 hours a day for emergency roof repairs.
- Where we work from
- Crumlin Drive, St Mellons, Cardiff. Llanrumney is part of our regular working area, alongside St Mellons, Rumney, Cardiff, Pontprennau.
- Post-war semis and short terraces
- The backbone of the estate. Concrete tiled roofs, rendered or pebbledashed elevations and timber rooflines that are usually the first part of the property to give up.
- Rendered and pebbledashed frontages
- Roughcast finishes are everywhere in Llanrumney. Once it cracks or blows off the wall behind it stays wet, so render repair and EWI both come up regularly here.
- Rear extensions and flat roofs
- Kitchen and dining extensions added over the decades tend to sit under felt or mineral flat roofs that are well past their working life and leaking at the upstands.
- Large front gardens turned to parking
- Plots here are wide, which makes Llanrumney one of our busiest areas for block paved and resin-bound driveways, dropped-kerb widths and new boundary fencing.
What We Get Called Out For Most in Llanrumney
Roof repairs on ageing concrete tiles
Slipped tiles, cracked ridge bedding and tired valleys after a wet winter. Often repairable, and we will say so plainly when a full re-roof is not yet needed.
Roofline replacement
Rotten fascias, sagging soffits and split guttering soak the render beneath them. Replacing the roofline in one go is one of the best value jobs on a house like this.
Driveway replacement
Worn tarmac and broken concrete swapped for block paving or resin, dug to a proper depth with a compacted sub-base and edge restraints so it holds its shape.
Render repair and external wall insulation
Cracked roughcast made good and sealed, or the whole elevation insulated and rendered so the rooms behind it stop feeling cold.

The Problems Llanrumney Properties Actually Have
Building age, ground conditions and how exposed a property is all change what fails first, and what the right fix is.
Exposed estate roofs catching the wind
Open layouts and wide roads mean little shelter. Ridge tiles, verges and dry-verge trims take the brunt and a loose one in autumn is a missing one by spring.
Blown roughcast holding water
When pebbledash separates from the wall it becomes a reservoir rather than a coat. Tapping the elevation tells us far more than looking at it does.
Flat-roof extensions leaking away from the fault
Water tracks along joists before it appears, so the stain on the ceiling is rarely under the hole. Finding the real entry point is most of the job.
Moss on shaded north-facing slopes
Moss holds water against tiles and blocks gutters, which turns a cheap maintenance visit into a repair bill if it is left for a few seasons.
Sunken drives on soft ground
Skimp on the dig and the sub-base and a new driveway ruts within a year under a family car. Depth and compaction are where a drive is won or lost.

Llanrumney, Your Questions Answered
Which parts of Llanrumney do you cover?
All of it: Ball Road, Countisbury Avenue, Braunton Crescent, Bideford Road, the roads around Llanrumney Hall and out towards Rumney and Trowbridge.
Do you actually cover Llanrumney?
Yes. Llanrumney 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 Llanrumney is a normal short trip rather than a long-distance job we reluctantly take on.
Is the quote free in Llanrumney?
Yes. Quotes and site visits in Llanrumney 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 Llanrumney?
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 Llanrumney 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 Llanrumney guaranteed?
Every job carries a 10-year workmanship guarantee: roofing, rendering and driveways alike. That guarantee is the same in Llanrumney 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 Llanrumney?
Yes. Waste goes with us, the working area is cleared, and we walk the finished job with you before we leave.
Can you repair a pebbledashed wall rather than re-render the whole house?
Often yes, if the surrounding render is still sound and bonded. Where it has blown across the elevation, patching only hides the problem and we will tell you that before you spend money on it.
Do you lay driveways on the wider plots in Llanrumney?
Yes, and the wide frontages here suit block paving and resin-bound surfaces well. We dig out to the right depth, compact the sub-base and set edge restraints so the drive carries vehicles properly.
