Extensions- 7 Oct 2015
Neil was brought in to construct a single storey extension to our house After trawling through numerous companies we were delighted to have found Neil as he is a bricklayer to trade unlike most other companies who are joiners who employ bricklayers and grounds workers and we know building an extension requires 80-90 percent brick and ground work and all other externals. From the moment my wife and I met Neil and his team we knew we had found the right builder. Right from the word go we could see the professionalism and after every day's work the site remained tidy.Communication was never an issue as we were always kept in the loop what was happening, when and where. Over all we are delighted that our extension came in at a good price, on time and and looks the way we wanted it too! Neil and his co worker Barry are two very friendly and easy to get on with guys. My wife child minds from home and this can cause a lot of problems when workmen come as we need to make sure the premises are kept safe and secure for the children.Neil and Barry always made sure that there was never any danger around and always maintained a high level of awareness making sure simple things like gates were closed and secured or any work areas were danger free. I also might add that all the kids thought that they were hilarious when they saw them and that in itself of making everyone feel at ease is one of many reasons why we will use Neil again and recommend him to anyone!

Hard Flooring- 23 Dec 2024
The team was on time, very friendly and professional. Old carpet was pulled, engineered flooring installed and glued, skirting removed and replaced. The flooring looks great and they've done an amazing job. We're going to do a second room next, and probably a few more things around the house. I'd definitely recommend them.

Electrical- 23 May 2019
C Hanlon have just completed the full rewire of the property and I am more than delighted with the quality of workmanship. Mark came out and surveyed / priced the job last week and whilst it was not the cheapest quote that I had, I progressed based on the fact that they were a local company who were able to start immediately and complete it quickly to a high standard. The job took only 2 days to complete and John, the Electrical Manager kept me fully informed throughout. I would have no hesitation on using C Hanlon again or recommending them to friends or family.

Extensions- 27 Aug 2015
Andrew and his team are all hard working, where the work is all to a high standard. All his workers are polite and work in all weather, often doing 12 hours days. The finish is better than I have experienced from other tradesmen. I was also kept abreast if on the rare occasion that someone could not turn up. It was clear that he showed a passion for 'doing it right', which included improving on the original plans. I am happy to recommend him and his team. A. HOLMS
