Bathroom Fitting- 21 Jun 2022
We are not entirely satisfied with Ludovic's work. Some of the tiles were not cut to the correct messurement which left big gaps in between. Worse still, the grouting was very messy and did not have a smooth finish. We will now have to get another Tiler to redo some of the tiling work. Overall, it was not a professional job and we are not very happy with his workmanship.

Extensions- 20 Jan 2014
We are so happy we chose to go with Iver construction to do the extension of our home. We shortlisted a few construction companies but liked the way that Mr Sanghani came over to explain their quote and went through how they would go about the job and was able to answer all the small questions I had about how I wanted things to be done. Very professional. The team was also very professional and very hard working. Everyday there would be some sort of noticeable work. they are a tidy team and would tidy any mess made. Obviously with all the dust that an extension can cause there was still some dust left but they cleaned up as much as possible which we appreciated. The communication with Mr Sanghani was very good. He would always pick up the phone when I called or call me back if he was busy no matter what time or day. After the job was completed when I had a few minor problems like cracks they came back to fix these . Even whilst building if there was something I did not like they would do their best to make changes. All in all very good, friendly and hard working builders. I have already recommended them to loads of my friends and family. Can not fault their construction skills.

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

An extension builder in Southfields 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?

Your Southfields extension builder should ensure the project complies with Building Regulations and, where necessary, handle or assist with planning permissions. Ask how they manage building control inspections and what documentation you’ll receive once the project is complete.

What experience do you have with similar extensions in Southfields?

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