Demolition- 5 Apr 2025
Work not of a great standard. I had to keep pointing out mistakes and they didn’t finish the job which means I now have to find someone else in order to do so. Also quoted me £1400 for plastering a room which I got done for £700!?

Fencing- 2 Sep 2020
I originally left positive feedback for Daniel as I was initially pleased with the fence job that he did. However Daniel by his own admission 'forgot' to re-attach the back fence to the new fence he had installed. Dan came back to fix this problem but unknown to me he had just put one very short screw through the posts achieving nothing. So when we had the recent winds down came my back fence and my neighbours new fence was also damaged. I called Daniel again to be told 'it was not his problem' nor part of his job to attach the joining fence. I have had a professional fencer come and assess the work who had advised it is of very poor standard and any professional would have secured the joining fence properly. Daniel has not used sufficient postcrete either around the concrete post. Unskilled or lazy, i'm not sure. Daniel eventually returned after letting me down to see if we could sort our differences. I advised Daniel that I was not expecting a new or free back fence from him as eventually I would have replaced it. However I did expect him to correct the bad work he had done. He agreed and left. However a few days later he has written to me telling me he is not going to do the work. Seems I am not the only person to have this experience with this trader. I strongly advise to avoid.

Spenhen Construction Works Ltd
No reviews yet
Extension Builder in Birmingham
SpenHen Construction is a professional family-based building company with over 30 years of experience. Both my dad and grandad were bricklayers and I, Spencer, started as work experience with my dad whilst at school and then started on my own after 10 years of working with him. Today it's been 16 years since I have worked in this field and the company has specialised in domestic extensions. The projects that excite me the most are when the client stretches my skills by wanting something different from the ordinary and breaking barriers of a standard box building. When a homeowner works with SpenHen Construction, our initial team of 4 will start the works for the first half, ground works elevations, brick work and renovating and then the second half consists of my project managing the trades, plaster, electrical, plumbing. A homeowner should choose SpenHen Construction because we truly care, not only for what the finished product will look like but also the process, we don’t cut corners or rush. I still want to better myself with every project and I enjoy both the physical side of my work and working with a client to help them achieve their dream home.
