Highlights
"We had Cso construction come to our home to build an extension on our property. From start to finish they did an amazing job. The guys were so friendly, professional and were brilliant with our children when they were asking them what they were doing ! Couldn’t recommend enough and will use them again for any future projects we have"
"Connor and his team are very friendly and we are really happy with the quality of their work. We are already getting a quote for our next project!"
"Connor is very friendly and accommodating. He used high quality subcontractors for the entire construction. We are very happy with the result and have used Connor for smaller jobs in the house."

Before you hire a builder
Never pay a large deposit up front — agree a staged payment schedule tied to completed milestones, and hold a small retention until snagging is done.
Get it in writing: an itemised quote with scope, materials, start and finish dates, and how any changes (variations) will be priced.
Be wary of a cash-only price or pressure to start tomorrow — both are red flags for an unaccountable job.
Ask to see a portfolio of completed work like yours, plus recent references you can contact.
Check the credentials and registrations that matter for this work — and that they are current.
Want an extra legitimacy check?
Run the Cowboy Checker on CSO Construction Ltd before you contact them.
