Bathroom Fitting- 16 Jun 2024
Harpreet not only finished this job, being kind, helpful and professional, ended up renovating some of the house hold things like changing gas hob, firting tiles etc, which I was thinking of doing later in year. He completed all the work in the time frame and amount charged was reasonable. He did great job in renovating the bathroom. He went out of way to help install loft stair case.

Extensions- 7 Mar 2026
Viktor is an excellent builder. He understands the needs of a complex job and mine was a huge renovation project. A side return and extension and full refurbishment of the house including the installation of 3 bathrooms, Kitchen, cupboards and much much more. It’s not quite finished yet but the house is transformed and the work was done incredibly fast, far faster than I had anticipated. I moved out for the duration but I was back in the house within 4 months. The language barrier made things a little harder than they might have been but we got by. If you have someone to project manage the job alongside Viktor I would suggest that but if you want someone who is really very good at his trade and runs a tight team I would recommend Mhilli Construction for your job.

Extensions- 11 Jan 2018
This was our first project, and we were exceptionally fortunate to find Bujar. We're actually getting tired of hearing our family and friends tell us how lucky we are and how amazing he sounds. One of the most honest, trustworthy, and genuine people I've ever met. If I had a problem, he'd be one of the first people I'd call! In fact I did last week and he came to the rescue :) His team were all friendly, polite, conscientious and very tidy. They worked around us as much as they could, always making sure we had access to what we needed which sometimes meant it took them longer to work. Bujar is a perfectionist and is so proud of what he does, he made sure everything was done to a high standard - the estate agent who came round after we were done was impressed! His prices are very fair (better value than other quotes we got and much less time). We couldn't believe it was done in the 3 months he said it would take, and we managed to fit in a few extra bits and pieces after that. He was so helpful throughout, took all project management on and didn't bother us unless an important decision needed to be made. He drove us around all over the place to sort kitchens, bathrooms, etc. and gave us really helpful advice throughout the process. Highly recommend him and his team. I can't imagine ever wanting to look for another builder unless I had to - something that is quite common amongst Bujar's clients. We are extremely pleased with everything about our new house.

Tiling- 25 Jul 2025
Shiv builders did the tiling for my bathroom. The quote was easy and done via a WhatsApp video. Price was reasonable. The job turned out to be more challenging than we first thought with uneven walls and floorboards were quite worn however they found solutions easily. The team arrived on time and did an excellent job. Always left the place tidy and very polite and professional. I then had a few additional jobs round the house such as changing door handles and fitting light pendants which they happily accommodated and again did a good job. Will definitely be using them for future work.

Carpentry- 27 Jul 2026
10/10 for this company; Guy was very easy to deal with,gave a reasonable quote for Garden Fencing(including preparing and raising concrete posts and gravel boards) and extending on patio slabs. He made sure that what was agreed on was what he'd deliver. I can honestly say, from start to finish it has been a pleasure doing this business with BCON, Guy takes pride in his work and definitely does not cut corners. Puts in a proper full days work, leaves property clean and tidy and completes the assigned job on time. Guy went the extra mile to source near to identical paving slabs when asked. I definitely will hold on to his details for future projects when they arise, with no hesitation to hire and recommend again.

Hard Flooring- 1 Sep 2026
I WANTED TO LEAVE A MINUS REVIEW BUT THERE IS NONE, THAT IS WHY I HAVE LEFT THE LEAST POSSIBLE SCORE. I PERSONALLY DO NOT THINK THIS GUY CALLED MARCO KNOWS ANYTHING ABOUT BUILDING AT ALL. HE IS A ROGUE BUILDER. HE SAID HE HAS 25 YEARS BUILDING EXPERIENCE, WHICH IS A LIE. I CALLED HIM TO DO MY FLOORING, KITCHEN CABINET, TOILET. PAINTING, FIXING LEAKS. HE RUINED THE WHOLE HOUSE. 8 MONTHS ON, WE ARE STILL REDOING ALL THE WORKS HE DID, HE JUST SPLASHED SILICONE ON THE UPVC TO FIX A LEAK. THE LEAK CAME THROUGH THE CEILING UNTO THE FLOOR CAUSING A BIG FLOOD IN THE HOUSE. HE IS THE MOST UNTIDY BUILDER. HE SAID HE WAS PAINTING, HE SPLASHED PAINT ALL OVER THE HOUSE, HE KEPT SAYING HE WILL TIDY IT UP AT THE END. UP TILL NOW, 8 MONTHS AFTER, I AM CLEARING THE MESS. ALL THE GROUT HE PUT ON THE TILES CAME OFF THE FIRST TIME I MOPPED THE KITCHEN FLOOR. ALL THE TILES HAVE MARKED PAIINT ON THEM AND IT IS EXTREMELY DIFFICULT TO REMOVE THEM BECAUSE THERE IS A LOT OF THEM.

Bathroom Fitting- 18 Sep 2021
During the quote nothing was too difficult and Iustin had some great ideas. 'You tell me what you want and we'll do it.' Great. Day one they caused a leak into the kitchen. Halfway through day two we ordered work to stop because it was still leaking. It took several calls to Iustin to resolve. The leak caused the extractor fan in the kitchen to drop. They fixed at the end but the lights on it don't work consistently. Attention to detail was zero. Floor not sealed behind cupboard, wobbly plaster, streaks of white paint on blue (and vice versa), chipped paint, and tiles not evenly placed, with roughly cut edges. New flooring laid before finishing the walls, dropping sealant, dust and paint on it. Many things had to be redone or changed - but they generally did redo when asked. A window they put in is lower than agreed and the pebbledash doesn't match. They installed the vanity unit on the wrong wall. No dust sheets were put down over kitchen surfaces when drilling through concrete, covering everything in a thick layer of dust. The project was contracted to finish by 4 September, but took until 15 September. Iustin did apologise for this on the last day. On the last day, Marin threatened us because we wanted to wait until the job was finished to send the final payment. At that point we'd paid £500 more in instalments than agreed. Receipts for materials contained items not used or not ours. They took away things that we'd paid for. Overall not a great experience.

What qualifications and experience do you have as an extension builder in Waltham Forest?

An extension builder in Waltham Forest should have a strong track record with similar projects and relevant building qualifications or trade memberships, such as the Federation of Master Builders (FMB) or TrustMark.

Will my home extension meet all building regulations and planning requirements?

What experience do you have with similar extensions in Waltham Forest?

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 Waltham Forest extension builder’s ability to deliver a result that meets your expectations.
