What a great experience we had with Louis. He is honest and gets the job done efficiently with great attention to detail. He did such a good job with our terrace. We had some problems that really needed a professional solution and Louis planned and executed it brilliantly. Instead of looking for excuses for things that could be a problem Louis had a great solution for everything we came across and was positive the whole time. Would highly recommend Louis, we already have him booked in for more jobs.

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.

We had the pleasure of working with Alfa Style Limited on our loft conversion and we can recommend them highly and without reservation. Their work is incredible, attention to detail outstanding – our build was done with care and precision. They turned up on time every day, worked incredibly hard and quickly. In addition, they were extremely clean and tidy in the workplace – they never left the worksite in disarray. This is the first time we have done such a big project – Ruslan, Slava and their team were amazing. They were brilliant at explaining what was going to happen, day by day, week by week and translated the more technical information! No question or query was too much. The service after the build had finished has also been great, calls to check everything is OK and any queries we have, they are only a phone call away. We have had so many compliments from family and friends who have seen the finished build … it has made a huge difference to our house, we could not be happier.

What experience do you have with similar extensions in East Finchley?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the East Finchley extension builder’s ability to deliver a result that meets your expectations.
