Restoration & Refurbishment- 21 Apr 2023
Marius accomplished a difficult work for my property. We had a heavy leak difficult to identify which required a couple of investigations. He finally gave me the price figure and estimated time to do the work and he managed to do it in a successful way all the way through. He changed all electric work under the stairs, completely replaced new joists, plywood and engineering floor on top. He changed the damaged staircase, solve the leak problem without causing big damage. Thank you for your business. Will definitely hire again for my loft conversion. Would highly recommend!!! Thank you for your business!

Sean was on time and very polite at all times. He completed the work very efficiently with no disruption whatsoever. He went out of his way to make sure the job was completed to our satisfaction. He cleared up afterwards and left the site very tidy. We would happily recommend Sean.

Bathroom Fitting- 7 Nov 2025
Amazing work done by Antonel and his colleagues! The job was done to a very high quality standard and they were very thoughtful towards my needs always keeping good communication from the start of the process. Antonel promised me a very tight deadline of 5 days and he made sure this was met, always ensuring the job was done to a very high standard, I couldn’t have asked for more. Definitely someone I would recommend to anyone.

Lack of professionalism! Called me at 2150 to say was interested in job, warning signal but said far enough so booked an appointment. He didn’t turn up nor respond to my texts asking if he was held up somewhere. I am not sure how trustworthy he is.

Bathroom Fitting- 10 May 2026
I hired Vasile to update my bath and fit a shower, as had none, and he did a fantastic job. Vasile works diligently and with honesty which is a rarity sometime in trade. He listened to my wishes, came up with ideas and never complained as I added more requests and made changes as we went on. Vasile’s work is precise and for someone who suffers from OCD, that was a great bonus. My bath/shower room looks fabulous and my friends are demanding Vasile’s number after seeing it. I have Vasile’s number saved for life, and will hire him from now on anytime I need something done in my house. Added bonus, Vasile is very reasonable with his pricing.

CTS Solutions Ltd
Rating: 5 out of 5
Extension Builder in Kings Langley
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.
