Conversions - General- 4 May 2025
I Hired Em to do my ground floor reno, which included a garage conversion and remodel of my kitchen where 2 internal walls were removed. Very glad I found Em to do the job. Him and his team was efficient, friendly, tidy and hard working. We encountered obstacles along the process (which is normal for any renovation) but Em gave his opinion, listened and we came to the best solutions. Very happy with the result. Em is a reliable, punctual, knowledgeable, fair, down to earth guy and one of the best if not the best contractor I have hired. Highly recommend. Some before and after pictures.

Extensions- 30 Nov 2020
A really excellent set up of builders. Peter was great in evaluating the work and what we needed done. Sue was clear in her communication on costs, and then execution of the works by Taras and his team was superb. The extension was built in fantastic time-frame, and the end result is great. The work-ethic of the builders is what really makes them so good. They are on-time every day, and relentless with working hard each day.

Conversions - General- 29 Dec 2021
We struggled to get anyone interested in our refurbishment project originally, Mark answered an ad for a small part of the job and ended up being able to take on the whole thing thankfully. Our project was to completely strip out a 1960's maisonette flat, install internal insulation which involved extensive battening of all the external walls, new plasterboarding & plastering finishes to walls and ceilings, tiling and a completely new bathroom and kitchen install. To complicate things further, as enthusiastic DIY-ers we wanted to do lots of works ourselves as well and few builders would have worked alongside novices as well as Mark did. He was always happy to give advice or take over works when we realised they were beyond our skills or time ;-) Our project was constantly evolving and challenging - as we discovered hidden rotting floor joists and the joys of 60's engineering - door lintels - who needs those?! Mark was always there to help us problem solve and get the job done professionally and to high standards and this was all done throughout the challenging last year of lockdowns etc. Without hesitation we'd recommend Mark and his team. He was always reliable, flexible as the project developed and had excellent attention to detail and we couldn't have completed our project without him. Thank you Mark!

Conversions - General- 3 Sep 2025
Big refurb of 1650 sq ft flat, plus building 2 additional ensuites. Initial quote seemed reasonable but then once in, costs started to rise exponentially. Some work was done well, like the building component and flooring, but finishing was poor. Painting, particularly of internal doors, was done poorly, without removal of fittings first, so lots of overpainting and insufficient prep and coats. Regrouting and redecoration of front and rear patios was done poorly, with weeds already poking through. There was damage to existing bathtubs and WCs by not protecting surfaces and pouring waste materials down the pan. Everything was an argument with constant demands for more money e.g. front door only painted one side as the other side not included under "paint door". Lots of "snagging" - I only have manual on/off control of heating and hot water as "smart" thermostat won't connect, there are odd water pressures through some fixings...and now there's a leak under one of the WCs...

Les and his team did an excellent job. He took the time to talk me through all the requirements, made a reasonable offer, and then executed the job, together with a team of co-workers, exactly as we had agreed - swift as the name of the company.

Extensions- 8 Dec 2017
We couldn’t be happier with the professionalism and quality of workmanship from REA Construction. The project was delivered within budget and on time. We lived in the property during the work and we, our neighbours and the site were always treated with the utmost consideration. There were almost no hitches and, when they did occur, they were dealt with immediately and thoroughly. Our project team, led by Kristjan and Besi, were universally hardworking, organised and produced work to an excellent standard. Communication is great, the people are wonderful. Renato was someone I felt I could trust from the moment I met him and he never let us down. He and everyone at REA genuinely care about what they do and that their customers have a happy experience. We certainly did and would have no hesitation recommending them to others.

Restoration & Refurbishment- 28 Aug 2018
We had the very intricate loft reconfiguration done with extra big size window installation and full refurb on our recently bought Victorian end of terrace. It was a great experience all along, starting from the quantity surveyor detail level quote provision to the sign off and snagging. I was pleasantly surprised by the attention to detail with what Lux Construction delivered the works, and project manager Jonas professionalism was exceptionally high from my personal experience. Upon such a great experience I have been recommending you to all our neighbours when being asked who did such a perfect job for us. Thank you once again.

Conversions - General- 5 Mar 2025
As a new homeowner, I embarked on a renovation project for my four-bedroom, 1920s semi-detached house. The renovation involved transforming the ground floor into an open-plan layout by removing structural walls, installing reinforced steel joists (RSJs), and replacing the existing flooring with vinyl tile (LVT). Additionally, a new kitchen was installed, along with underfloor heating and air conditioning. Kaiser arrived at the site with a notebook, took precise measurements, and consulted with the structural engineer. He was transparent about the scope of work included and excluded, and his quote was the lowest when all quotes were normalized to include or exclude materials. Throughout the project, Kaiser maintained complete transparency, and no supervision was required. Communication was always prompt and effective. The renovation was completed on time, and I wholeheartedly recommend Kaiser. I am confident that you will not be disappointed by choosing Kaiser.
