Extensions- 19 Apr 2020
After spending months of planning and finding the perfect company to execute our Porch we decided to Hire Has Constructions LTD. We are very thrilled with everything that was done. Everything has been completed to the highest standard and exceeded all expectations. You can genuinely tell they take pride in their work as they always go above and beyond for every task to ensure perfection and satisfaction. Anyone considering Has Constructions LTD should not hesitate and should contact them for a quote. They may be new to MyBuilder but certainly not new to the trade. They have decades of experience and knowledge. My family found them very experienced and knowledgeable with all regulations and trade standards. In our Porch, some of the tasks they completed included, foundations, block and brick work, guttering, drainage, new roof, roof tiling, electrical planning and wiring, plasterboards, lighting, plastering, painting, tiling, interior door frame and door installation, installation of a composite door with side glass panes, celotex insulations, k render finish and laying driveway paving. They really did all the above which highlights the range of tasks and knowledge that they have in this field. Please see their photos for examples of their work and be assured you are in safe hands. They are reliable, honest and very fair. Would highly recommend to anyone.

Restoration & Refurbishment- 19 Nov 2019
Iljaz and his Team were brilliant! I was slightly concerned having no reviews. They found the leak, fixed it and patched up the wall in very tidy and professional manner. He did say he wouldn't be able to come today and updated me, however he made time to come in-between his day to sort out my issue. Not many true trades people like this and very honest and stuck to his word. I would definitely recommend him and would not hesitate to use his team again. Thank Iljaz!

Restoration & Refurbishment- 29 Mar 2018
A pleasure to deal with . Agim and his team worked hard to a very good standard.They often worked later than i would expect so that they were ready to move onto the next stage of the job the following day. Agim was very knowledgeable of all building regulations and was ready to offer me solutions when they were needed. All his team were courteous , polite and also knowledgeable. This was the first time I have used A&B but I would have no hesitation of using them again and recommending them to others.

Extensions- 19 Jun 2016
Neno is a very warm-hearted and genuine person. He gives his 100% to the job. He is also very prompt when it comes to communication and is always available by phone/text/email. He has a vast experience and good technical know-how and produced excellent plans and drawings. His quotes were very reasonable and offer excellent value for your hard earned money. Having been his client, I am genuinely inclined to believe he is a person who would never "rip off" his clients. He is a man of his word and does what he says. However, Neno's honesty and confidence can be a bit blunt at times. He can be quite “direct” with his opinions and this may rub off some people the wrong way, e.g. your local Council Planning officer may be an a**hole, but if you "confront" him, he will definitely not make things any easier for you- nevertheless, Neno dealt with all the Council red tape and followed up the Planning Permission Application to its conclusion. We finally got permission for extending the property much less than what we had expected initially- apparently our local Council (Hillingdon) has its own set of Draconian conservative rules that we were unaware of- but we have postponed the actual project work due to a recent change in personal circumstances. Summary: Based on my personal experience, I would DEFINITELY RECOMMEND Neno as a bona fide Tradesman on MyBuilder.com.

Please avoid this company for many reasons. There work is absolutely shocking and the owner is incompetent and should be ashamed of himself how he left my job. I’ve tried to contact Elijah and he’s blocked me, he’s an absolute disgrace. I will put up pictures of his work so you can see how bad his work is.

Bathroom Fitting- 9 Jan 2015
Aggi and Pedro were excellent. They helped me to decide what fixtures and fittings I needed (including also doing some research themselves) and when it came to fitting the new bathroom they did it to a high standard and were tidy/cleaned up after themselves. I would recommend them.
