Your Local Team in Marshfield
Marshfield sits on the Wentloog levels between Cardiff and Newport, a straightforward run from our yard in St Mellons. Marshfield Road, Wellfield Road, Church Lane and the lanes out towards Peterstone and Castleton are all part of our normal working area.
It is a village with two kinds of housing side by side: older cottages and farm property with slate, stone and traditional render, and later estate and infill housing with concrete tiles and rendered or brick elevations. What they have in common is exposure. There is very little shelter out on the levels, and that shapes what fails and how often.
Wind and wind-driven rain are the deciding factor here. Ridge tiles, verges, flashings and chimney details take far more punishment than they would on a sheltered city street, and fencing needs posts set properly rather than knocked in and hoped for. Flat ground and heavy soil also mean driveway and patio drainage has to be planned rather than assumed.
We cover new roofs, roof repairs, rendering and external wall insulation, block paving, resin driveways, patios, fencing, jet washing, kitchens, bathrooms, painting and decorating. Free quotes, fixed prices in writing, full public and employer's liability insurance, a 10-year workmanship guarantee, and 24/7 cover for emergency roof repairs.
- Where we work from
- Crumlin Drive, St Mellons, Cardiff. Marshfield is part of our regular working area, alongside Castleton, St Mellons, Newport, Cardiff.
- Older cottages and farm property
- Slate, stone and lime render with working chimneys. Traditional materials and methods, especially on the weather-facing elevation.
- Village estate and infill housing
- Concrete tiled roofs with dry verges and uPVC rooflines, mostly needing detail repairs, driveways, fencing and rendered finishes.
- Large plots and outbuildings
- Garages, stores and workshops with tired flat or sheet roofs that are usually the first thing to leak on a property like this.
- Long boundaries and open frontages
- Fencing runs here are long and exposed, so post depth, concrete and gate hanging matter far more than panel choice.
What We Get Called Out For Most in Marshfield
Storm damage repairs
Lifted ridge tiles, displaced verges and stripped flashings after a blow. We are contactable 24/7 for live leaks and wind damage.
Fencing that survives the wind
New posts set to depth in concrete, panels fixed properly and gates hung square, so a long boundary lasts rather than flattening in a gale.
Driveway drainage on flat ground
Level ground and heavy soil mean water sits. Block paving and resin both work here, but only with falls and drainage designed into the job.
Render and exterior weatherproofing
Cracked or blown render on the exposed side made good, or the whole wall insulated and rendered for warmth as well as weather protection.

A short run along the A48
Marshfield is minutes from our base in St Mellons, so a site visit is a normal trip rather than a special journey with a charge attached.
We build for exposure
Fixings, post depths, flashing details and edge restraints are specified for where the property actually is, not for a sheltered street.
Old and new property both covered
Traditional slate and render work alongside modern tiled roofs, resin drives and fencing, from the same five-strong team.
Fixed prices, free site visits
A written fixed price after an in-person look at the job. Never a day rate, and no charge for the quote.
Insured with a 10-year guarantee
Public and employer's liability insurance, and a 10-year workmanship guarantee on everything we complete.
The Problems Marshfield Properties Actually Have
Building age, ground conditions and how exposed a property is all change what fails first, and what the right fix is.
Full exposure on the levels
There is nothing between these properties and the weather coming off the estuary. Anything loose on a roof does not stay loose for long, it goes.
Standing water on flat ground
Water has nowhere to run out here. Patio falls, driveway drainage and gutter discharge all have to be thought through or the ground stays wet.
Wind-driven rain into render cracks
Rain pushed horizontally into a hairline crack does far more damage than the same rain falling straight down onto it.
Ageing outbuilding roofs
Garage and outbuilding roofs are usually older than the house roof and are frequently the actual source of a damp problem.
Long fence runs failing at the posts
Fences almost never fail in the middle of a panel. They fail at the post, which is the part worth spending money on.

Marshfield, Your Questions Answered
Do you cover Marshfield and the surrounding lanes?
Yes. Marshfield Road, Wellfield Road, Church Lane and out towards Peterstone, Castleton and the levels are all inside our normal working area.
Do you actually cover Marshfield?
Yes. Marshfield 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 Marshfield is a normal short trip rather than a long-distance job we reluctantly take on.
Is the quote free in Marshfield?
Yes. Quotes and site visits in Marshfield 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 Marshfield?
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 Marshfield 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 Marshfield guaranteed?

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 Marshfield?
Yes. Waste goes with us, the working area is cleared, and we walk the finished job with you before we leave.
Can you deal with storm damage quickly out here?
We answer the phone 24 hours a day for emergency roof repairs, and we will tell you honestly when we can be with you rather than promising a time we cannot keep.
Will a new fence stand up to the wind in Marshfield?
It will if the posts are right. We set posts to a proper depth in concrete and fix panels and gates to suit an exposed boundary, because that is where fences fail.
