Restoration & Refurbishment- 7 Oct 2025
I recently hired Aman for a full refurbishment of our home in Northwood, lasting 6 weeks. The project included a kitchen and bathroom makeover, new patio, skimming, electrical works, tiling, decorating and a new staircase.The standout feature throughout was the exceptionally high-end finish. Quality of work: The craftsmanship was outstanding across all trades. The kitchen and bathroom featured premium finishes, seamless tiling, flawlessly skimmed walls, and a patio with a refined, high-end look that tied the indoors and outdoors together. Professionalism: Aman was courteous, communicative, and easy to work with. I received regular updates, clear explanations of decisions, and transparent timelines. Reliability:The project started on schedule and milestones were met as planned. Cleanliness & safety: The site was kept pristine and safe throughout, and well protected. I would have no hesitation in recommending Aman for refurbishment works.

I had a complete bathroom refit, with a separate toilet done to match. The work was carried out to a high standard and Paul and the team worked long hours every day and never left a part of the job half finished. They were early every day and worked throughout without taking lunch breaks. Paul and the team were extremely knowledgable during the refit and if a problem occurred, as they always do, they were quick to offer alternatives but never to the detriment of the job. I was extremely pleased with the final look of my bathroom and would willingly recommend Paul for further jobs.

Extensions- 11 May 2018
After a rogue builder left me with 18 (eighteen) structural issues. Lez and his crew came in transformed my failed extension into a masterpiece. All aspects of the job was done to the highest quality and utmost care and attention to detail was shown to building control needs. They cleaned up after every day and made sure the house was habitable, as I had to live there. Every aspect of the build, from the carpentry, plastering and tiling was first class and their recommend electrician and plumbers were from the same stock. Total professionals. My only regret is that I did not use this builder the first time. The prices were reasonable and even building control had good word to say about their work. Thanks Lez
