Bricklaying- 25 Aug 2024
AVOID. Ernie incorrectly installed my drains under my house which has caused awful smells and sewage to leak under my house causing long term damage to my foundations Three professional drainage company’s have put a camera to see a Dropped pipe from new to old house. They have identified a connection that was never appropriate. Unfortunately, Ernie after being given many opportunities does not accept any responsibility. He is not an expert at all trades so be careful. I’ve asked him to help put right by exposing the floor which has Underfloor Heating. This has now cost me tens of £000s. My fault for not using a professional team at the beginning of my project.

Bricklaying- 28 Jan 2025
I recently hired A1&PM to carry out structural repairs on my house, including replacing window lintels and providing complex temporary works to support the structure during the repairs. They also patched plaster, skimmed a wall, rendered, and repointed an external wall. From start to finish, the team was professional and reliable, turning up on time with all the necessary tools and materials. Protecting carpets and covering furniture. Their knowledge and expertise were evident throughout, and they completed the work exactly as promised. The pricing was very competitive, and the quality of the work exceeded my expectations. I was initially sceptical due to some past review, but my experience couldn't have been better. I would definitely use their services again and wouldn't hesitate to recommend them to others. Fantastic work—thank you!

Extensions- 28 Sep 2018
Johnny was very nice to deal with. When there were problems they were quick to find ways to rectify them. They started at short notice& finished on time which I was very impressive. We got a no. of quotes,Johnny was middle of the range but with a better level of service than others. Johnny was very open about when things might cost more &gave us the option if we wanted to proceed. A few things to note: -this was our 1st experience of any building work &we should have remembered they are builders, not designers -we both work long hours &so most days didn't see the team to get an update or brief them. This meant a few things were missed or miscommunicated - while most of the team were lovely the electrician used was horrible to deal with. He got very cross about requested changes, didn't deliver everything requested &just did silly things like putting in a light switch with 2buttons where there was only one Light or hanging lights incredibly low when we had given measurements of where we wanted them - we got Johnny's team to build some extra storage for us which on the whole was fine but some things weren't centred or for example the wine rack they built was wonky Overall, it was a good experience and we would recommend them but would suggest be home to oversee the work more than once a week (must be true of any building work!) and get your own electrician. Very happy to talk to people and give references-the house looks great now.

Bathroom Fitting- 9 Feb 2019
Alexandros did an exceptional job with our bathroom. As it was our first major renovation we were very anxious about the whole process but Alexandros made everything very easy and smooth from the beginning until the end. Alexandros has a lot of experience and he is full of ideas and good suggestions. The new bathroom looks amazing and we could not have chosen better than Alexandros. Alexandros was very helpful throughout the whole process. I would highly recommend Alexandros to anyone and we will definitely use his services in the future.

Extensions- 19 Jul 2021
Jitender/Tinku and his team were excellent from the first time we met. They provided us with ideas to better our layouts, helped with sourcing a number items and put us in contact with suppliers which helped us achieve more competitive prices. I was kept updated with the progress regularly and most importantly the project was completed on time and within budget. Shah Builders take real pride in their work and it shows in the finished product. We are very pleased with the outcome of the project and have recommended Shah Builders to friends and family.
