Extensions- 30 Aug 2018
my experience of working with these guys was very positive. i eventually got a new kitchen fitted by them rather than an extension as the extension was above my budget. Their pricing was competitive, although not the cheapest. i made a conscious decision to offer the project to sall construction because they were experienced, and they were detail orientated with my plan as well as the fact that their timeline matched my project timing. the kitchen fitting was done, in fact, slightly ahead of the two weeks that sunny had said it would take-which was very useful. we also went on a holiday and left the whole place to them, and everything worked out for us, so clearly very trustworthy. sunny and his brother were excellent tradesmen and came back twice later on once we notified them of some small issues. its now been 1 year since the installation of the kitchen, and fingers crossed, everything looks and works great. everyone is impressed with our kitchen which is also indicative of their very good work. I will happily hire them again if i have to do some work on extension or refurbishing.

Restoration & Refurbishment- 19 Apr 2025
Positively, certain aspects of the finishing, particularly tiling, were carried out to a good standard. However, the overall experience was mixed due to significant issues. There were notable challenges during the project involving basic logistics and site management, leading to considerable inconvenience that seemed avoidable. Furthermore, the quality of workmanship was inconsistent; while some parts were good, other areas involving fittings and fixtures showed a lack of attention to detail in the finish, requiring later adjustments. Communication during the process could also be difficult, particularly regarding problem-solving and planning for materials. While we appreciated the parts done well, the project was let down by these inconsistencies and process issues, leading to some ongoing snagging and disappointment.
