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.

Only two companies expressed an interest in my exterior decorating job, the first being situated +/- 50 miles away which, logistically seemed less than ideal and certainly not local. The second, Haus Company, was closer to my location and was awarded the job. The team of two, Robbie and Paddy, worked hard during a torrid heatwave and completed the work in 5 days as planned. The finished work more than lived up to my expectations in terms of quality and I'm happy to recommend Haus Company.

There was a watermark around the inside of my Velux window which suggested a slow leak. Danny responded and agreed to come and look at it, he kept me informed about the day and time. He wasn’t able to do the repair on the day but provided me with a reasonable quote. He arrived to complete the work and again kept me informed about a change in the time. The work was done more quickly than he had anticipated and the price was revised down. A nice polite individual who I will have no hesitation in using again.

Following some work done successfully in 2022 by this company, I reached out to have some similar work done in 2024. However, I paid a deposit for the work, the job was never started, communication stopped, despite me reaching out via phone and email, and I never received my deposit back. Highly disappointing after a great experience the first time round. I would not recommend.

5 Star Fencing was absolutely superb - came to site on the day agreed, replaced the three bowed fence panels with ones of very good quality and painted them to match the rest of the fence, and did a small repair on an existing panel - Callum of 5 Star Fencing was an absolute pleasure and left the site (my garden) all clean and tidy.

My main work is carpentry joinery, but also do the whole job, ie repair or redo the wood work, repair the plaster and redec. I have worked on national trust buildings, repairing to perfection and because I love gardening I do garden tidies and make overs as an extra side line.

Job didn't last long, started leaking again when it rained heavy. wasted money. Another company looked at the chimney and flat roof and politely described the job as done by cons, using this site to get quick cash from urgent jobs, which if not done professionally costs more in the long run. The banter is part of the deception.

Do not use this trader. I have used Wayne in the past and he completed the job as quoted. Re-booked again this Easter to supply and fit carpet. He took the cash (over £1000) and we have been unable to contact him since. Currently going through small claims to try and get our money back.
