Conversions - General- 10 Feb 2024
Absolutely brilliant job by Billy and Chris! What at first looked like a cracked chimney turned out to be a lot worse. They kept us informed every step of the way, and in very adverse weather conditions completed the job. I would very highly recommend Northfield Contracts Ltd. If you want a very professional, friendly company to do your job.

Ricky was unable to do the job as Arwen arrived which made him more in demand than he expected. I followed his intentions to remedy the leak and did the job myself

Groundwork & Foundations- 17 Jun 2026
Overall very unsatisfactory job and just left in the lurch with promise after promise to get it sorted. I requested 2x60mm electrical ducts and got 2x40mm drain pipes (too small and not electrically suitable). The concrete pad was left with the shuttering installed and despite requesting it be level with the surrounding ground it was 3" above putting me at risk with the planning for the construction to be erected onto it. The waste was not removed from the site leaving me to have to hire a skip and do it myself.
