Lee converted our property from a 4-bedroom house into a 6-bedroom HMO, and he did an amazing job while keeping to the agreed 6-month timeline. Lee and his team delivered on every expectation at every stage of the project, which included a loft dormer conversion and a rear extension. They also completed six en-suite bathrooms, a new kitchen, a full rewire, plastering throughout, plumbing, joinery works, damp-proofing works, and installed new fire escape windows throughout the property. Lee managed the entire process professionally and ensured everything was signed off by Building Control. To date, Lee and his team have completed six properties for us, and we will continue to use them in the future because of their reliability, professionalism, and consistently high standard of workmanship. We would highly recommend Lee and his team to anyone looking for quality building work.

Replacement of a conservatory for a larger more eco friendly and useable space to comprise a kitchen, dining and family room. Shea and his excellent team completed the work to a very high standard and I am very happy with the result. In addition he was charming, friendly and efficient as were his colleagues in the trades who completed their various roles in a friendly manner and with an obvious level of expertise and pride in their work. I plan to have Shea and Mountfair Homes back again for my next round of home improvements and cannot speak highly enough of them.

Cramlington Builders demolished our existing conservatory and built us a beautiful sun room on the same base. I was delighted with Michael and his team, they were really professional and very switched on. Michael was a great communicator and was ever so reliable. When the glazing turned up to site it was Michael who immediately spotted that the wrong glass had been delivered and that it was not safety glass. We would never have know that and Michael had the glazer return to site to swap the glass. We found the team to be happy in their work and they delivered a really great project for us on-time. The price was the cheapest of the three quotes received and we will definitely use Cramlington Builders again.

Landscaping- 27 Feb 2021
Gary and his team cut corners from the beginning. A job that was quoted to take 4-6 weeks ended up taking around 14 weeks and even then was not completed by gary and his team due to him walking off the job. They used substandard materials which meant things needed replaced before the job had even finished. Overall the “finishing touches” for the job were absolutely horrendous. A child’s playhouse had nails sticking out of the wood. The nails in the fence had all rusted, the lawn wasn’t laid correct so couldn’t drain. The level on extension was completely wrong. Gary himself was quite rude and Him and his team were extremely unreliable. 100% would not recommend, save your time, money and sanity

Extensions- 28 Oct 2020
Dave Market (DMP Building Solutions) came originally to view a lounge extension I was intending on building but we agreed on a kitchen extension due to front elevation restrictions imposed by the council. He talked us through the process and gave us a very positive vibe. He put us in contact with a surveyor and we went through a lengthy planning process which stalled our build for approx 9 months. No fault of Dave. The build started in July and completed in October. Council Building Inspectors threw a few curve balls in and Dave also had a few personnel changes to his team during the build, however his dedication and professionalism never wavered from the goal. We now have a beautiful extension with a sloping roof incorporating a velux window. A nicely tiled floor and panelled ceiling along with new additional units, tiling, plumbing, woodwork, plastering all done to a very high standard. Where Dave finds issues or wants professional assistance he has a wide range of experts at hand including, roofers, electricians, gas specialist, window/door fitter, kitchen fitters. He doesn't make do with tasks he uses these professionals to ensure things are done right. The outside has been finished in matching brick and slate with white pvc pipework and guttering. All very easy on the eye. I'd recommend DMP solutions to anybody wishing to have an extension built and I'm sure other work would also be completed to just as high a standard.
