Bricklaying- 17 Dec 2024
They initially gave a fair price and a date and timeline that fitted with our needs. Subsequently they over ordered on the bricks so we had over 100+ expensive London bricks left over and they under ordered on sand and cement.(Luckily the shop took them back but we had to deliver them there) The job took far longer than they had said although the poor weather did not help much which could not be helped. The worst was that the wall was finished so that the latch of the gate could not be fitted as the wall was a bit too long! The wall looks good but their customer service and time given for job as well as ordering materials needs some improvements. They are pleasant workers, not rude in speaking

Rating: 5 out of 5
Extension Builder in West Acton
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.

Bathroom Fitting- 2 May 2024
I have employed DL Construction to install a new kitchen and bathroom. They are still working in my house but so far their attitude towards their task and helpfulness have been exceptional. I can not comment about the final product yet but I am sure everything would be finished to a high standard. Nothing seems to be a problem for Javi. He always says 'yes please' and I think that is his middle name. I couldn't have asked for better. Well done (so far) Javi and everyone in DL Construction.

I have been using HS Construction London for many years ranging from a full house refurbishment to smaller unexpected issues. I have always found them to be reliable and genuine. There are never any hidden surprises in the end. Sunny listens to his customers and also gives decent advice where needed. Their work is of quality and has a long life. I particularly impressed with how they complete the job in a timely manner. All the materials that have been used are of great quality; and it shows. In addition, HSC has many contacts such as architects, suppliers etc which has made my life so much easier. Reasonably priced and with great knowledge, i would certainly use them again.

What experience do you have with similar extensions in West Acton?
