Extensions- 19 Jul 2018
We hired C&C Construction managed by Billy Clarke to construct, in my parents house, a rear kitchen extension, new d/s toilet conversion, new kitchen build, new front porch, new external walls, gate and patio to the rear, all drainage, water supply & plumbing, electrics, gas fitting, tiling, finishes and decoration. Found Billy and the team extremely hard working, polite, diligent and committed to a high quality finish, but at an affordable price. During the build they were able to accommodate my parents remaining living in the house and built up a great relationship with my Mum and Dad. They encountered problems along the way as the house is from the 1930s and they had some dubious previous building standards to contend with, but dealt with them all as they went along. Very high quality on external render, and the new kitchen build and the new patio area is a delight. Mum and Dad, the clients, are delighted with the finished product and overall I would have no hesitation in recommending Billy and the team for any future works by C&C. Regards Terry

Extensions- 23 Dec 2021
We originally asked Aaron to come look at the property before we purchased to understand the possibilities of a large extension. Since that point over a year ago Aaron has worked with us in refurbishing the existing house as well as building a large wrap around extension. The core team we had on site of Aaron, Dan, Karl are hard working, they care about what they do, and they are good fun to be around. Aaron also has a broad network across all the other trades - all of which did a great job on the project. I would certainly recommend them for any work you are considering.

Extensions- 21 Jun 2017
COWBOYS! Absolute Nightmare! Marius left the job incomplete, after repeatedly demanding more money before completion! Not to be trusted! Workmanship wasn't as good as he would lead you to believe, I have pics & videos of: Cigarette butts in mortar. Bricklaying in the rain, not water-tight roof/felt work, drainage, unsafe electrical work which needs to be redone. Left my neighbour side of roof damaged + with a hole now for a month. Damaged door/table/gate. Of course, he denies any wrongdoing Please be very careful if you have to use this fraud. Get a FULLY detailed itemised quote! Draw up your own contract - do not use his. Do NOT ever pay CASH. Produce a schedule of works - pay him ONLY when the specific task is 100% complete - leaves lots of work unfinished but then lies claiming its complete at interim payments. Get a FIXED price for every aspect of work - do not have "TBC" or ambiguous costs - if he can charge more - he will. Do NOT use his electrician, cringeworthy attempt to "price up" a simple job and damaged roof. Buy ALL Materials yourself OR require receipts for anything he buys. Request ALL Invoices. Ensure he follows specs - offered me £250 off total job cost, if I used a inferior type of rooflight to the one required in spec. Ensure he doesn't keep rubbish on site, Hire a skip. Keep all communication on record, email, text, even voice record him as he is a pathological liar. Very dishonest, delusional and frankly embarrassing.

The team completed a large single storey extension approximately 12 months ago. The quality of the work carried out was of a very high standard and it still looks as good as it did when it was completed. The additional tradespeople that were brought in for specific tasks were all highly skilled and professional. The work quoted for was carried out on budget. As the work progressed, various additional tasks were needed but options for each of these were discussed and costed before they were undertaken. Communication was straight forward. We would not hesitate to use the company again if we need any further building work carrying out. before being undertaken,
