Craig got in touch quickly, gave me a rough estimate over the phone and answered all my questions. Surveyor arrived on time, gave instant quote. Price was good. Michael and (another) Craig turned up to do the job on the day, time given. Good, tidy job. Can't fault anything, from start to finish!! Would recommend!

George and his team are experienced builders, replaced my front door with a custom frame/sidelights and raising the floor level in the hallway quite quickly - in fact, they were the only who came next day, gave a quote straightaway and were ready to start in just couple of days. They also had all the necessary tools and materials, were ready to buy something additional quickly on the day - if further adjustments were required to fit everything as I asked. Thanks a lot for your help, guys!

Dmitry

Highly recommend. These guys did a fantastic job of constructing our pergola and decking. Very hardworking and reliable. The job was completed in the time frame agreed and to a very high standard. We would 100% use them again.

Andre and team did a great job with the shed /summerhouse construction, and were very accommodating with the request to build it at short notice ( (within 5 days) and alter the layout of the building to meet our requirements. Also were very friendly and professional. Reasonably priced too. Would recommend.

After initially posting for a small garden job at home, instead spontaneously requesting a quote to inspect the condition of a roof on a commercial property. Jesse recommended installing replacement rain goods. These works led to the discovery of a serious issue, that he and his team were immediately able to address, using incredibly high standards of workmanship, culminating in a substantial roof upgrade. Jesse and his team were professional, courteous and extremely tidy. I am delighted with the outcome.

I was very satisfied with the results of VFurb's external renovation and decoration work, which took 3 weeks in total, extended due to rain. Dragos worked six days a week to keep me informed of progress, answered all my questions, and identified practical solutions to unforeseen problems, supported by detailed costings . He was always present to supervise his team of 2-4 workers, and personally completed the most complex roofing, piping and guttering jobs himself to a high standard.

Placed advert Thursday. Contacted same day by Mike with a view to coming out and quoting next day. Came on time priced the job on Friday and arranged to start work on the Tuesday. Mike worked with his son Silas. What a really nice pair. Genuine, polite and got on with the job even though I asked for a few tweaks along the way. Both very old school and worked at their own pace - happy with work carried out and will use them again. Reasonable price too.
