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.

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.

Roofing (Flat)- 9 Nov 2020
Darren & Son (plus Team) responded promptly to our advert for a Roofer in My Builder, they accessed the repair and quoted quickly. The work required was worst than expected but they tackled it with professionalism and speed and kept us informed of the work being done (via photos). They also cleaned up and disposed of all redundant waste. Thank you once again guys for being able to sort out what could have been a potential bigger problem and I would recommend then to anyone.

Extensions- 6 Aug 2022
Majid has been great in producing drawings for our rear extension. He's also helped explain the whole build process to us from design, building inspection, and building. We received our drawings in under 10 days from the initial consultation and site visit. Majid was accomodating and was able to visit the site on weekends for the initial consultation. Always a pleasure to deal with and has been easy to reach over the phone or email. Would highly recommend Maji and MYD Studio London to anyone looking for an architect.

What qualifications and experience do you have as an extension builder in Sevenoaks?

An extension builder in Sevenoaks should have a strong track record with similar projects and relevant building qualifications or trade memberships, such as the Federation of Master Builders (FMB) or TrustMark.

Will my home extension meet all building regulations and planning requirements?

What experience do you have with similar extensions in Sevenoaks?
