Electrical- 25 Jan 2023
Gentjan was a thorough professional and a true gentleman. Quoted competitive price, came exactly on time and did job to very high precision. There were some unexpected issues (due to my bespoke kitchen setup, but he improvised amazingly - thinking out of the box. I cannot recommend him enough. Will definitely use him again.
CTS Solutions Ltd

Extension Builder in Hemel Hempstead
A specialist loft conversion company that has been in business for 20 years, however, we have since branched out to all types of projects (extensions, refurbs, garage conversions etc). We can prepare and submit drawings on your behalf, for Planning Permission and Building Regulation Approval. Also, we can carry out the structural design, meaning you don't need to employ an architect! However, if you have drawings done already, we are happy to price your project and build from these.

Asset Lofts came to our rescue when another company had let us down. They were professional and genuinely supportive right from the outset. The loft conversion (inc. full chimney removal) and patio works were completed in 5 weeks and this in our eyes was a building miracle. The workmanship and finish is of the highest standard. They hold accreditation with many of the industries leading bodies and that sets them apart from others. We highly recommend them.

Conversions - General- 25 Jul 2026
Would highly recommend - the process and communication was incredible from start to finish. Sukh was really helpful and thorough, helping us understand the whole process of our renovation and breakdown of the costs, talking through our floor plans and analysing the videos we sent. Really appreciated the flexibility and transparency to work within our budget, time scale and adhering to property regulations. Work was done excellently and promptly, within agreed upon timeline and all furniture was covered. The crew was very considerate with cleaning up after and very kindly handled all the disposal of material for us.

Plastering- 25 Feb 2020
Rob provided a very reasonable quote and started work on time as agreed. He scraped the artex, boarded sections, prepped and plastered both ceilings over two evenings to a very high standard. Both ceilings were ready to paint after a few days drying and were smooth with no trowel marks or hairline cracks at all. Rob also assisted with measuring up my kitchen for a new kitchen to be installed, he provided a better quote than Wren to fit the new kitchen, I will be proceeding with Rob to fit my new kitchen units based on the advice he has given me and the high standard of work he has carried out for me over the past couple of weeks. I would highly recommend Rob to anybody and I will be contacting him again for any future work I need assistance with whilst refurbishing my new property.

Restoration & Refurbishment- 28 Apr 2024
I highly recommend these people if you want to be fleeced, taken advantage of, treated appallingly and work left unfinished. The standard of work is below average. If you want high quality finishing do not come here. I’ve had to spend a lot to redo a lot of their mistakes and mess. If Jerzy could charge you for every single nail he would, so beware. And when you challenge, they get aggressive and nasty. Very unprofessional. Do yourself a favour and keep away. So thanks Jerzy and co for a load of stress and rubbish. I am happy to talk to anyone and advise against these people.
