Extensions- 12 Aug 2018
Broad Construction did an excellent job from start to completion. They were very punctual, helpful and conscientious. They were also very responsive to any queries or issues that undoubtedly arose during the project. They built up my trust which meant I didn't need to be on site, they were more than capable to get the job done to a very high standard. I would highly recommend them to anyone. We are looking to use them again for our next project.

Bathroom Fitting- 30 Jun 2017
We were impressed with Dave - he knew we'd been badly let down by a plumber/builder - and he offered to do the jobs we needed doing for a fair price. That was about 3 months ago. Since then communication has been a major problem - the lack of it. Emails, calls and texts unanswered. Promised start dates came and went without further contact. In the end Dave responded to a message by saying he wanted to pass the job on to someone else who we knew nothing about. Since then there has been no reply to our last email and he's disappeared! We're back where we were 4 months ago! Thought that using My Builder would end this sort of thing.

Extensions- 17 Jun 2022
Hartwell Projects came in to complete our extension. Right from the quoting process Jonathan was polite, timely and very knowledgeable. As our first building experience we knew very little about what needed to happen - Jonathan was patient, calm and answered all our questions and spent a lot of time on site with us making sure we were happy with everything. Jonathan was also transparent at all times willingly offering different solutions which ranged in prices to try to accommodate and make sure we made the best choices for us. When the build started we were amazed at just how clean the site was left everyday, and the progress and speed at which the build happened. Jonathan has a great core team working for him and each and every person was polite and so hardworking, which sums up Hartwell projects really well in our eyes. Attention to detail was always on point and each team member was happy to stop and talk to us when we returned home from work. The site was left secure each night without fail if we had to work late. During the build there were times that certain things weren’t going as smoothly (as with all projects there’s the odd surprise) but the speed of Jonathan’s reaction was fantastic and was quickly sorted, at all hours of the day Jonathon was available to answer any questions or worries. We wouldn’t hesitate to recommend Hartwell Projects for any project, if we ever need any future work doing Jonathan will be our first contact. ⭐️ 5 Star Service ⭐️

I would not hesitate to recommend White & I construction LTD to anyone who is considering building an extension or making internal modifications. The job was completed as required and although we were abroad at the time, Ivan ensured excellent communication including photos and videos at each stage of the project. All issues were dealt with quickly and each stage of the project was completed to the required timeline. On completion of the project snags identified were rectified immediately to our satisfaction. I would like to use this opportunity to thank Ivan and his team for a job well done. Dave & Kathleen Frankland

Joe came to fix a leak in my bathroom flat. The leak turned out to be a lot worse than we had hoped. Joe re quoted and got the much bigger job done without hesitation. He kept in constant communication with me, got the job done with in the time frame he estimated. Very polite and professional. Would absolutely recommend him!

Reliable. Versatile. Gets the job done. I’m a hands-on builder with years of experience across all areas of domestic construction—foundations, brickwork, kitchen fitting, groundworks, bathrooms, structural alterations—you name it. I see the bigger picture and keep projects moving without the usual delays or excuses. Homeowners trust me to handle full renovations without cutting corners. Contractors use me because I can jump into any part of the job and make things happen. If you’re fed up with chasing different trades and just want someone who shows up, cracks on, and finishes to a high standard—get in touch. I don’t mess about.
