Your Local Team in Penarth
Penarth is a short trip from our base and a town where the housing deserves care. Victorian and Edwardian villas and terraces around the town centre and Windsor Road, larger period property on the hill, and newer housing towards Cosmeston and the marina all sit within a small area.
Two things define work here: age and exposure. Period roofs run natural slate with lead detailing, decorative ridges and bay roofs that reward proper repair and punish quick patching. At the same time the town faces the Channel, so weather works on render, timber and fixings continuously.
We carry out new roofs and roof repairs, rendering and external wall insulation, block paving, resin driveways, patios, fencing, jet washing, plus kitchen fitting, bathroom fitting, painting and decorating, so period property can be looked after inside and out by one team.
Every job is quoted free and fixed in writing, never priced as a day rate, and covered by a 10-year workmanship guarantee. We are fully insured, and available 24/7 for emergency roof repairs.
- Where we work from
- Crumlin Drive, St Mellons, Cardiff. Penarth is part of our regular working area, alongside Cardiff, Vale of Glamorgan, St Mellons.
- Victorian and Edwardian villas
- Slate roofs, lead valleys and flashings, bay roofs and decorative ridges. These need matched materials and correct detailing, not sealant.
- Period terraces near the centre
- Rendered and painted frontages that face the weather, plus shared roof details with neighbours either side.
- Sea-facing property
- Anything looking out towards the Channel takes salt air and wind, which shortens the life of render, paint, timber and fixings.
- Newer housing at the marina and Cosmeston
- Younger roofs, so the work is mostly driveways, patios, fencing, rendered finishes and interior improvements.
What We Get Called Out For Most in Penarth
Slate roof repairs done sympathetically
Matched slates, sound lead work and correct laps, so a period roof keeps looking right as well as staying watertight.
Render and exterior paintwork
Coastal weather strips finishes quickly. Preparation is what decides whether the next coat lasts two years or ten.
Driveways within tight frontages
Period frontages are often narrow and walled. Block paving and resin both work, but the levels and edges need planning.
Patios and garden hard landscaping
Level, well-drained patios that suit the property, plus jet washing to lift years of algae from existing paving.

No inflated claims, just what we can actually stand behind.
Careful with period property
More than 15 years of trade experience on slate, lead and render, with repairs specified to suit the age of the building.

Penarth is a short run from St Mellons, so visits and follow-ups are simple to arrange.
Coastal-aware specification
Exposure, salt and wind are factored into materials and detailing rather than ignored until the job fails early.
Fixed prices in writing
Free inspection, written fixed price, and no day rates, so restoration work has a known cost.
Guaranteed and insured
10-year workmanship guarantee, public and employer's liability insurance, and 24/7 emergency roofing cover.
The Problems Penarth Properties Actually Have
Building age, ground conditions and how exposed a property is all change what fails first, and what the right fix is.
Salt air and sea wind
Constant coastal exposure corrodes fixings and degrades render and paintwork far faster than inland streets a few miles away.
Ageing lead and valley details
Victorian roofs rely on lead. When it splits or fatigues, water enters at the hidden junctions and damage builds before anyone sees a stain.
Original slate reaching end of life
Slate can outlast its nails. Once slates are slipping regularly, isolated repairs stop being economic.
Trapped damp behind the wrong render
Applying a modern impermeable render to an old wall can hold moisture in. Getting the specification right protects the building.
Shaded, north-facing hard landscaping
Mature trees and enclosed gardens keep paving damp, so it greens and turns slippery through winter.

Penarth, Your Questions Answered
Do you work on period properties in Penarth?
Yes, regularly. Slate roofing, lead valleys and flashings, and traditional render work are all part of what we do, with materials matched to the property.
Do you actually cover Penarth?
Yes. Penarth 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 Penarth is a normal short trip rather than a long-distance job we reluctantly take on.
Is the quote free in Penarth?
Yes. Quotes and site visits in Penarth 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 Penarth?
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 Penarth 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 Penarth guaranteed?
Every job carries a 10-year workmanship guarantee: roofing, rendering and driveways alike. That guarantee is the same in Penarth 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 Penarth?
Yes. Waste goes with us, the working area is cleared, and we walk the finished job with you before we leave.
Can you repair rather than replace a Victorian slate roof?
Often, yes; it depends on the condition of the slate and the fixings. We will tell you honestly whether repairs will hold or whether you would be paying twice.
Do you lay driveways on narrow period frontages?
Yes. Tight frontages need careful planning of levels, edges and drainage, and we quote that in properly rather than discovering it halfway through.
