Extensions- 14 Nov 2019
Bogdan himself is extremely knowledgable and his years of experience in industry is clear to see, which makes choosing him great value for money. Before and during the project he offered solutions that we hadn't considered and the would in fact save us money and be of benefit to us in the future. His team is punctual, reliable, diligent, speedy and clean! They take pride in their work which has led to a highly satisfactory work in the final build. Bogdan also has great connections to third parties (e.g. to flooring and curtains/blinds providers) which is very valuable, especially when trying to coordinate different aspects and timings of a full house redecoration. His quotes and payment structures are fair, clear and concise which is also very helpful. His communication is excellent too. All in all, Bogdan's great work took away a huge amount of stress during these projects. I would highly recommend Bogdan and his team for any prospective works someone is considering.

Hard Flooring- 30 Nov 2024
Very disappointed,they are not answering my calls anymore.At the first time I was happy-the builders seems polite and professional .After they left I realised that the work wasn't done properly i noticed bumps all over the floor,making look terrible.when.They had to comeback and finish the job that I already paid them for the silicone around the edges.when they returned they just completed the half the work and they told me they will finish the kitchen after.When I pointed out the bumps everywhere they claimed because they had walked on it.But after checking the bumps are everywhere on the floor and the issue was uneven subfloor.They had told me they were trying to flatten the surface before installing the floor and they just added more glue instead of properly levelling it,as professionals they should have fixed this before laying the LVT. Now I’am left with a poorly finished floor.Very disappointed,frustrated.Would not recommend unless they fix their work .

New extension, kitchen, shower room, flooring, fiber glass roof, roof light, new electrics, plumbing, boiler installation, removal of chimney, rear patio, soakaway, painting and decorating Satnam has exceeded our expectations in carrying out the complete job to our satisfaction within the agreed time to a very high standard.

He was honest, courteous, professional, flexible, open to changes and made suggestions to improve the overall look. He even passed on his builders' discounts to us. We highly recommend this ambitious young builder who has excelled in the trade. We wish Satnam and his team the very best.

Akash made sure the job was complete exactly how he said it would be, he provided reliability during the installation of our kitchen and answered all questions very professionally. The builders were well aware of the conversations my mother and I had with Akash and so put our mind at ease. The installation itself was very quick (the tear down was very much completed in a few hours) and installed over the weekend. They were very hygiene aware and set up a cover between the kitchen and the rest of our house and didn’t disrupt our home living. They cleaned up before they were gone to very high standards without us even asking them too, all I’m sure is due to Akash’s excellent organisation skills.

What experience do you have with similar extensions in Marlow?

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