Tiling- 21 Jun 2021
Great professional and reliable service from Easy Solution. Waqar called me ASAP and arranged to see my bathroom. He came within 1 hour to see the job and gave me an affordable and good quote. He was available to start work immediately. Waqar also suggested the colour of tiles that would suit the bathroom and made some very good recommendations on where i could purchase them at a decent price. My work was done to a high standards. Tiles are neatly put together with grout and they are looking amazing! I had some many relatives comment on them and i have recommended Waqar to them all as i was so satisfied with his service and professionalism in my property. I will be using him always in future. Thanks.

Electrical- 9 May 2026
He was good on price for the first inspection and attended as agreed. However, I was less happy with the remedial quote. Several items quoted did not appear to be needed, while some items that did need attention were not included. Overall, fine for the inspection, but I would have preferred a more accurate and practical quote for the follow-up work.

Bathroom Fitting- 5 Nov 2019
I met up with Peter, told him what needed doing and he provided a detailed quote within days. I handed over a set off keys and basically left him and his team to get on with it! This was a time restricted job, he purchased all the material and provided all the receipts. I returned a week later to find the job completed to the highest standard surpassing my expectations. I will definitely be working with Peter again in the future and I would highly recommend him.

Garden Maintenance- 17 Sep 2017
I hired DS Developments to completely landscape my small front garden. This involved clearing and levelling the area; moving and re-securing a bike shed; laying a patio and lawn; and a number of finishing touches. The area went from somewhat of an embarrassing eye-sore to an area of pride. One that several neighbours have already made compliments about. David provided a professional service from start to finish. His quote was more than I expected, but his knowledge and vision gave me the confidence to select his services. He provided a selection of options and stuck to budget; adapted well to new ideas/suggestions; and informed in advance where the cost would be impacted. He and his team also were as tidy and considerate as possible and I highly recommend their services.

My wife and I have been truly impressed by Victor and Tom's quick turnaround and willingness to get the job done to an extremely high standard.

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.

Very few tradesmen can engage in a detailed, professional and friendly manner. They took out an old kitchen and replaced it with a new one - which the helped source at below market cost saving us in excess of £5000. Right from conception to finish, there was full transparency of the costs and crucially at the end, no cost overruns. Definitely five stars and will reengage again for other building/renovation works I have planned.

Kitchen Fitting- 18 May 2017
Cannot fault the work Tony undertook. Completed on time, finished to a very high standard, kept informed (we were away on holiday whilst work was being done). So pleased with the result, my daughter's room is what was the kitchen and looks beautiful. New kitchen fitted with new floor tiles and looks fantastic, boiler was moved etc. Can't recommend Tony enough and I will definitely use Marsdens again.
