Hey! Jordan & Jamie here, we’ve just created our first business together after almost 9 years of being in the construction industry, we have a lot of passion and love for the work we do. We’re both 25 years old and have been friends since 16! We both went into bricklaying in Bromley college at 16 years old and both qualified Level 2, Since qualifying I (Jordan) went into roofing and building loft conversions with my uncle Jamie kept at the bricklaying with one of his friends dads, until recently (since may 2024) he joined me in building loft conversions. we’re loft conversions specialists in the week and on the weekends were bricklayers haha. We both thought making a business together would be fun as we share the same passion for it and we love working hard. We’re young, work hard, very communicative with our customers and do a high quality job.

Conversions - General- 31 Aug 2018
Danny and the team (Scott, Darren, Dayne, Dennis) were fantastic, consistently working to find more effective, lower cost solutions. We enjoyed working with him so much we then took on a significant amount more work with him, that involved a full fit out of a fitness studio. Danny has a wide network of individuals with many areas of expertise he can call on when necessary. In a couple of the really difficult moments of the project Danny went over and above what you would expect. We were delighted with the work and will be recommending him going forwards - although I’m sure everyone wants his time!

Conversions - General- 25 Feb 2016
I used Matthew to knock my old kitchen through to the garage and convert the old garage into a new kitchen and bathroom. I have to say that from the first recce/quote he was extremely thorough and helpful. He and his wife Lisa were brilliant all the way through the job, always going the extra mile with customer service and managing the project efficiently. They were professional providing insurance, schedules of work and payment plans in advance and were great at coordinating other tradesmen like window fitters, electricians, roofers etc. As with all building projects we came across a few hiccups but Matthew dealt with these excellently and was always good at keeping me well informed on everything. I was more than happy leaving Matthew and his workers in my house when I was out and they always cleaned up after themselves. They were always flexible when I changed my mind on minor things and even arranged a tiler when I decided last minute that I wanted to get that done too. They even finished the job on time and I am extremely thrilled with it. Would happily recommend Matthew and his team of people and would definitely use them again.

Victor (Vica) laid some engineered oak wood flooring for us in a house that we bought at the end of 2013. The house needed lots of work doing and the new flooring was just one of the many jobs undertaken by Victor and carried out to a very high standard for us. He always paid attention to detail, ensured that the flooring was level and that the new skirting board fitted flush to the floorboards. He was also always able to provide a solution to any problems encountered during the renovation works. I would have no hesitation in recommending Victor as he takes the same pride in his work for others as if he was carrying out work in his own home.

Conversions - General- 22 Jan 2019
If you're looking for a building firm you can rely on through thick and thin, then look no further. We engaged MMP to knock through both a kitchen/dining room - removing two chimney breasts - and an outer wall to install bi-fold doors, in an old Victorian house we had recently moved into. Andrew came to quote and was courteous, knowledgeable and described the schedule of works clearly. Unfortunately, after works began, structural issues that were not pointed out in the survey arose, that required immediate remedial work for our original works continued. I feel that many small building firms would have washed their hands of the project a this point, but Andrew diligently suggested Structural engineers, liaised with the local Borough Council building control, and even helped pen letters to the surveyor asking for recompense for their faulty Homebuyers survey. Obviously, due to this, the project took longer than we had originally envisaged, but Andrew and his team were often at our house late into the evening, tidying up after a long day of work. The building works were completed last week, and we're thrilled with the result. The new doors look great and, even before the new plaster is painted, we're really happy with how our new room looks. Every day of works, I'd get an email from Andrew, listing the works carried out, any problems that had arisen, and many photos of the progress. If you want piece of mind that you're not getting cowboys, give MMP a call!
