Latest review:
We recently bought flat to let and decided to do completely refurbish. We invited few quotations including Gurwinder. We shortlisted top 3 quotation and invited him for discussion. During the meeting he was very professional and full of ideas. So we decided to honour him. Work started as agree on time, during the Job we liked his ownership of the work and advising us on the very step of the decision. Although it would have been better if his communications were more punctual but it neither affect us nor delayed any work. Even after completion he has been very helpful if any issue arises ( nothing major).

Extensions- 3 Oct 2022
I gave him the opportunity as I was desperate to find someone fast,and didn’t have much success on here.Soon as he accepted,he was already asking for cash beforehand to get materials.I thought you know what,his company details are online,what can go wrong so I did.As his team started the job, they told me I needed to have 2 fences erected as they were badly damaged and deteriorating.I thought heck,why not,might aswell do it now so I gave him again, the opportunity to make some extra business with us.Again,was asked for some pre payment to get the materials,all in cash.All was finished within 2days of the weekend.Fence looked fine,but the roof just looked like a cowboy job.I didn’t complain,as it was done fast,with all the stress with opening a new business,it was one less headache out of the way.After 1 day of rain,the roof was already leaking,like absolutely everywhere.Called him, and he got someone to come by a few days after to fill in more silicone.(Very suspect job again).I thought fine, aslong he’s responding and trying to fix the situation.Fast forward few days later, bearing in mind the shop isn’t open and I’m not always there when it’s raining,it rained again and it was leaking in some areas again.Whatsapped him which is how we normally communicated,called him,read my messages but no reply. Now he has blocked me.Seriously, how he knows I’m opening a business soon this is how he wants to treat his customers. Simply give me back my money or fix the problem, simple!

Garden Maintenance- 10 Jul 2026
Ranj cleared my back garden, which was towering full of weeds/ nettles and our front drive. His is extremely good value for money. He removed all the garden waste too. I was so impressed with the work. Not one weed left behind. Everything was pristine. Excellent attention to detail. Super friendly service, super hard working and we were super pleased with how the back garden and front looked. Definitely recommend him.

What experience do you have with similar extensions in Acton?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the Acton extension builder’s ability to deliver a result that meets your expectations.
