Bricklaying- 13 Aug 2022
Complete waste of time. Hired this tradesman a few months ago, to work on a simple brick BBQ. We had a conversation in person about the job and i informed him i would be supplying the bricks as they are "reclaimed". On the day they were to start the job, he turned up and said "oh" where are the materials, which was concerning. I had to explain our conversation in detail to point out that i said i was supplying the brick as they were reclaimed, no mention of any other material. I had just completed a huge renovation project and this was one of the final contractors to be used. Unfortunately this person is very amateur, and he then made me pay £500 for materials to be delivered. I paid for the materials and the new start date he suggested wasnt suitable, he then said he longer wanted the job! Can you believe it, he made me pay for all the materials, even though that was not agreed in person. I have dealt with over 12 different teams working on this project, and this one is the worst. No care in the word, he even sent a text said he was "quaking in his pants" about a bad review. I just replied saying, that sums everything up - totally unprofessional. Move on.

Kitchen Fitting- 31 Jul 2019
To say Nick is just a kitchen fitter isn’t doing his work justice, he’s a fantastic project manager and craftsmen as well. When we first met Nick he took 2 hours of his time running through all the options which was when we realised we were actually quite clueless! Although we hadn’t hired him at this point his advice was invaluable. We assumed this would mean Nick’s professionalism would mean he would be very expensive, this was not the case and he was actually a little cheaper than the other parties who quoted. Once Nick started it became apparent that he and his assistant Chow to great pride in their work and worked hard to get the job finished as quickly as possible to the highest standard. They left the site spotless at the end of each day. The result is a fantastic kitchen and flooring which we are extremely happy with. We are already thinking about the next renovation piece in our home and would love to use Nick again. Thanks Nick! Niall & Hannah

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

An extension builder in Dagenham 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.

What experience do you have with similar extensions in Dagenham?

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