  • From the very first meeting with AJM Contractors, we knew we were in safe hands. Our project involved a loft conversion and extension, the demolition of a chimney stack to create one large room, staircase remodel, installation of an en-suite, custom wardrobes and painting. With a toddler, a dog, two cats, and both of us working from home, it was essential we found a team that delivered quality while being respectful of our space. AJM made the whole process unbelievably stress-free. Armanjeet, owner and PM, was fantastic. He was on-site nearly every day, always available to speak with, and incredibly responsive via phone and WhatsApp. His communication style gave us complete peace of mind, and we always felt informed and involved. The whole team were polite, respectful, and hardworking from day one. They arrived at 8am and worked solidly until 5pm, even through a freezing winter. Their attention to detail was second to none, and their knowledge across all aspects of the build was invaluable—they provided thoughtful advice on both aesthetics and practical solutions throughout. They even helped collect deliveries (including from IKEA) and introduced us to trusted contractors for carpets and decorating—helping us get great deals. Nothing was ever too much to ask. By the end of the project, the team felt like part of the family—we’ll genuinely miss them. If you’re looking for a skilled, respectful, and reliable contractor, you won't be disappointed.

  • Based on a friend’s recommendation, we recently had our bathroom renovated by AJM Construction and couldn’t be happier with the results! From start to finish, AJ & his team were professional and skilled at their craft. Despite us changing our plans relatively last minute, they provided great design suggestions, showed very high quality of workmanship and were super reliable. From coming at agreed times, working while we were out of the house, over weekend work for timely completion; to helping us pick-up materials, what impressed us most was their trustworthiness.

  • We had some housekeeping issues initially, however AJ ensured his workers fully respected our property when we raised our concerns. The work was done to spec and drawings and there were no hidden extras and generally to program. Could not fault the standard of workmanship, anything that we weren’t happy with AJ was more then willing to change things to ensure we were happy with he final end product. AJ and his team were non-confrontational throughout the process and they kept within the boundaries of the site works and our home, that made a huge difference when you have children. I will use AJ construction again.

  • We recently hired AJM Construction for a major house renovation, including a porch extension, kitchen-diner opening with steel, a new kitchen, and bathroom renovation. AJ was fantastic to work with—open to discussions and always ready to support his team. His crew was punctual, hard-working, and went the extra mile. Mandeep, in particular, had a positive attitude and offered great suggestions. We're already planning additional work with AJ and would highly recommend his team for home renovations.New List Item

  • As Builders were recommended by my mum after they completed a conversion for her neighbour. Called her neighbour who I am friendly with, and he couldn’t recommend them enough. I was completing a huge renovation on a four bedroom home including a rear extension, new electrics and plumbing for thee whole house. So I was very nervous about choosing the right builder, especially after hearing horror stories from some of my friends and family. I can honestly say I have been truly pleased with the professionalism, workmanship, patience and reliability. I would definitely work with them in the future. My house is absolutely amazing!!

  • AJ, Mandeep and the boys are very friendly and trustworthy. I would definitely consider them again for construction work. The project started in May and finished in October, but we got the kitchen back at the end of August. This was a month or so behind target due to delays in Magnet and window delivery. It was a kitchen refurb with many structural changes, removing two chimney breasts, installing a steel the length of the kitchen, knocking through to the lounge, widening the door to the balcony and installing steels to support both new entrances. Relocating services to the opposite side, installing an additional radiator and underfloor heating, tiling, and kitchen . We had a new sliding door set which we arranged ourselves. Outside leading up to the kitchen, the decaying Victorian stone staircase and balcony was demolished and replaced with a metal painted black staircase and balcony. The outside of the building was re-rendered and painted and a redundant window was filled. The patio was extended to accommodate the slightly extended staircase and underneath where the brick foundations were previously. Just before the start of the refurb, the old dishwasher leaked and made a hole in the basement ceiling. AJ also quoted for and did the basement ceiling and converted the old Victorian outside toilet into an inside one to make it nicer and fit a small utility, and block an exposed drain rerouting waste pipe to outside, to box some exposed piping and repaint.

  • We would highly recommend AJ and his team. We did a 6 month project with them and are very happy with the standard of the work that was carried out. The team are extremely skilled and hard working. They were always on time, worked long days, were flexible, and friendly. They carried out a few extra jobs like fitting insulation in between the floors, which we weren't expecting them to. Would definitely work with them again in the future.

  • Armarjeet was above and beyond. He came through a recommendation and surpassed the expectation that was set. They worked around the clock, over weekends etc to get the job done and were flexible working with other suppliers. They did plastering, cementing, painting, fixing damp issues, electrics radiators - the lot. They also had all the contacts for carpets, floor sanding etc too which was very helpful. Armarjeet was like a project manager - he went out and bought all the paints, things from screwfix, toolstation - the lot.

  • I found AS Builders through Which? Trusted Traders when looking for a reliable builder to complete a rear kitchen extension. The work was carried out between July and November last year. Despite a number of unexpected but unavoidable issues arising during the work (related to the period nature of the property and the poor standard of workmanship carried out for previous owners by other builders - for example a smaller previous rear extension had to be demolished entirely and new foundations dug) , Amarjeet and his team took things in their stride. They were hard-working, polite and flexible and carried out the work to an excellent standard. I wouldn't hesitate to recommend them or to use their services again for further work to my property.

  • Hello, The usual experience with builders is over-promising, and then a steady-state of frustration and bills that come in above the quote. Building is a hard industry, really hard! There are so many moving parts, and Armajeet and his team take it in their stride. They're always smiling and incredible to work with. Nothing is too much, even if you do change your mind. My girlfriend is also an interior designer so she was very specific about the house, and they never complained. On a number of occasions, Armajeet helped out or went out of his way to make our lives easy beyond what is imaginable for what a friend might do, let alone a builder. He is a special person, and I feel like I could call him a friend after working with him for 6 months full house refurb. This review isn't fake or a hoax, and I guarantee the other 5 star reviews won't be either. Feel free to contact for a reference if you would like. Thanks.
